    [0001] PROCESS OF TREATMENT OF PURINES AND PLANT TO CARRY OUT SAID
    [0002]
    [0003]
    [0004]
    [0005] OBJECT OF THE INVENTION
    [0006]
    [0007] The invention, as expressed in the statement of the present specification, refers to a slurry treatment process and a plant to carry out said process, providing advantages and characteristics, which are described in detail below, which represent a Novelty for the current state of the art.
    [0008]
    [0009] More specifically, the object of the invention is focused on a process and a slurry treatment plant consisting, essentially, in separating the solid part of the liquid from the liquid and carrying out an individualized treatment of both parts, including, the treatment of the part lfquida a pre-treatment with centrifugation that reduces all the organic matter and almost all the inorganica and a subsequent treatment of the liquid obtained with ozone injection that makes it deodorized, disinfected and having eliminated, almost in its entirety, ammonia, potassium and the phosphates present in the liquid fraction. For its part, the treatment of the solid part leaving the separator is mixed with the organic matter of the centrifuge and sent to a digester, which, after a period of reaction, will produce sulfur-free biogas and a deodorized, disinfected and stabilized fertilizer. , suitable as a subscription.
    [0010]
    [0011] FIELD OF APPLICATION OF THE INVENTION
    [0012]
    [0013] The field of application of the present invention is part of the sector of the industry dedicated to the treatment of waste, focusing particularly on the field of organic waste from livestock farms, and more specifically to the animal slurry.
    [0014]
    [0015] BACKGROUND OF THE INVENTION
    [0016]
    [0017] As it is known, although according to the dictionary purfn is the liquid formed by the urine of animals and what oozes from manure, the expression purines refers to any of waste of organic origin, such as waste water and vegetable remains, crops, seeds, concentrations of dead animals, fishing, food, solid or liquid excrement, or a mixture of them, with the ability to ferment or ferment that have an environmental impact.
    [0018]
    [0019] The present invention, however, is mainly focused on animal-type slurries which, generally, are residues resulting from a mixture of urine, the liquid part of that oozing from all types of animal manures.
    [0020]
    [0021] The slurry of pigs is the best known because they are very polluting, mainly due to the swine concentration in diverse points, for which its control is obligatory. They have an approximate content (in proportions of Kg per ton) of 2 Kg of nitrogen, 0.5 of phosphorus and 3 of potassium.
    [0022]
    [0023] At present, the recycling of pig slurry for various uses is being studied, the objective of the present invention therefore being the development of a process and a treatment plant for that purpose.
    [0024]
    [0025] On the other hand, and as a reference to the current state of the art, it should be noted that, although other processes with the same objective are known, at least on the part of the applicant, the existence of any slurry treatment process or plant is unknown. similar invention with characteristics equal or similar to those presented by what is claimed herein.
    [0026]
    [0027] In this regard, it should be noted that one of the main advantages of the process and the plant described here is found in the biodigester, since, unlike the known processes, four phases of operation are required to react the product with four different types of ph, working normally in proportions of 40% solid matter and 60% water, in the present invention the biodigester works continuously and semi-dry process, since the proportion is 98% of matter solid and only 2% of water, using for the fermentation a specific type of bacteria that does not affect any antibiotics that may contain the material to be treated, with the exception of contraceptives.
    [0028]
    [0029] EXPLANATION OF THE INVENTION
    [0030] The slurry treatment process and the plant to carry out said process that the invention proposes are configured, therefore, as a remarkable novelty within its field of application, since according to its implementation and in a exhaustive manner, the objectives outlined above, the details that make it possible and distinguish them conveniently collected in the final claims that accompany the present description.
    [0031]
    [0032] Specifically, what the invention proposes, as pointed out above, is a slurry treatment process consisting, essentially, of the following steps:
    [0033]
    [0034] - separate the solid part of the purfn from the liquid part and carry out an individualized treatment of both parts, where:
    [0035]
    [0036] - the treatment of the liquid part comprises, basically:
    [0037] - a pre-treatment with centrifugation that reduces the organic and inorganic matter - and a proper treatment of the liquid obtained by means of ozone injection with which it is deodorized, disinfected and without ammonia, potassium or phosphates,
    [0038] - and the treatment of the solid part comprises, basically:
    [0039] - its mixture with the organic matter obtained from the liquid part in the centrifuge - and its passage through a continuous working digester with only two chambers in which, after a period of bacterial reaction, it produces sulphurous-free biogas and a deodorized fertilizer, disinfected and stabilized, suitable as fertilizer.
    [0040]
    [0041] More specifically, the separation stage comprises the following:
    [0042]
    [0043] From a slurry collection chamber, where an agitator, a level switch and an underwater pump are installed, the purfn is pumped to a separator, compactor type of four hundred microns, where 63% of the solid matter is separated (organic matter). ) of the liquid.
    [0044]
    [0045] The treatment step of the liquid part comprises:
    [0046] - A pre-treatment step: which contemplates the mixing of the liquid part with coagulant, binder as liquid pro-lamida, and antifoam.
    [0047] - And a treatment stage: in which the liquid obtained in the pre-treatment stage is injected with ozone.
    [0048]
    [0049] To do this, the liquid part that leaves the compactor type separator to a first deposit. This deposit is fiber, two cubic meters, and has a butterfly valve incorporated, a water sprayer for cleaning it, for which water is used by the system itself, and a level switch.
    [0050]
    [0051] At the exit of the first fiber deposit there is a coagulant dosing agent composed of 70% inorganic coagulant and 30% organic coagulant, a liquid pro-lamida dosing machine and a screw pump that drives the mixture to a centrifuge from the which, in turn, is conducted to a second tank where antifoam is added and from there the product goes to a turbine pump that sends the liquid to a third tank or treatment tank.
    [0052]
    [0053] The centrifuge reduces 100% of the organic matter that reaches it and 90% of the inorganic matter, separating these solid elements from the remaining liquid.
    [0054]
    [0055] In the liquid treatment tank, ozone is injected, recirculating it with an ozone pump, adding coagulant and ph regulator. To do this, the third tank or tank of treatment that is larger, between 10 and 60 m3, with a built-in level detector. When the determined level is reached, the liquid is recirculated, through another pump with which the ozone is injected, until the end of the treatment.
    [0056]
    [0057] By recirculating the liquid part and injecting ozone we get the oxidation of the ammonia formed by a nitrogen atom (N) and three hydrogen atoms (H) according to the NH3 formula. The ammonia has a great solubility in water due to its polar character since the molecule is not flat, but has a tetrahedral shape, in which each atom of hydrogen occupies a vertex and the fourth is occupied by the electronic pair of the hybrid orbital sp3, occupied in its entirety.
    [0058]
    [0059] This polarity inherent in its molecular structure gives it a good solubility in water where it behaves as a base when forming the ammonium ion NH4 + (each proton is located at the vertex of the tetrahedron formed by sp3 hybridization).
    [0060] The solubility in water at 20 ° C reaches 34% by weight, ie approximately 34 g / 100 mL.
    [0061]
    [0062] This amount is much higher than that in the water from the centrifuge treatment, so it will remain in solution and will not "evaporate" or "release" to the atmosphere until its chemical composition is altered, that is to say until that a different chemical compound forms that reacts differently.
    [0063]
    [0064] The nitride anion will be transformed into molecular nitrogen by means of the oxidants present in the water and therefore the only chemical species that will be released will be molecular nitrogen, N2.
    [0065]
    [0066] This process also reduces, practically in its entirety, the phosphate and potassium compounds that precipitate in the matter and that are separated by a flotation process with the use of a brush.
    [0067]
    [0068] The ozone reduces until its elimination all the biological flora, including coliform bacteria.
    [0069]
    [0070] The properties of ozone cause the liquid fraction to be deodorized, disinfected and the ammonia, potassium and phosphates present are almost completely eliminated.
    [0071]
    [0072] At the beginning of the recirculation and, next to the ozone pump, two dosing pumps are started: one that injects coagulant with a percentage of 70% organic and 30% inorganic and another with a product that regulates the pH.
    [0073]
    [0074] When the level detector reaches the maximum, the dispensers will stop, sweeping with a brush over the level of the liquid; this system agglutinates the organic and inorganic matter by flotation and removes it from the process.
    [0075]
    [0076] Following the treatment tank, a bypass has been provided which passes the liquid through a sand filter. For this, an open turbine pump of 50 m3 empties the treatment tank and recirculates the liquid dividing the flow into two circuits activated by two butterfly valves. One of them circulates its flow through a sand filter to later join the other before entering a three-way valve from the that can be taken directly to irrigation or a fourth tank of treated water.
    [0077]
    [0078] For emptying the treatment tank, the 50 m3 open turbine pump preferably has two motorized valves that act by sending the water to said fourth tank of treated water, which may consist of a raft for irrigation.
    [0079]
    [0080] In case you want to obtain a greater reduction of the dissolved parameters, you can send the treated water back to the first tank, after the compactor-type separator, to start the process again.
    [0081]
    [0082] In addition, optionally, a part of the treated water will serve to feed the needs of the process in the plant: cleaning of filters, deposits ..., so that the system needs a minimum contributions of water from the network.
    [0083]
    [0084] In case the obtained water does not reach the desired parameters for its use as irrigation water, it will optionally be circulated by a nanofiltration and then by an osmosis system, so that the conditions required for the process are achieved.
    [0085]
    [0086] It should be noted that the water or liquid fraction treated that is going to be used for irrigation may be stored for a while before being used. For this, optionally, in the fourth tank or treated water tank where it is stored, an RMI or Instant Mixing Reactor is installed with the intention of keeping it in the best conditions.
    [0087]
    [0088] For its part, the treatment stage of the solid part of the purfn comprises the following:
    [0089]
    [0090] - The shipment of the solid part that leaves the separator (compactor), preferably together with the solid part obtained in the centrifuge of the liquid part, to a bio-digester that works continuously with only two compartments, where it remains about 21 days fermenting with a specific bacteria.
    [0091]
    [0092] For this, the solid part falls into a cone that has a symphon that introduces it into the bio digester.
    [0093]
    [0094] The digester, as has been said, has two compartments, and a bell that collects the sulfurous gases along the entire length of the deposit and passes them through a filter, thereby obtains sulfur-free biogas.
    [0095]
    [0096] The first compartment receives the solid material and incorporates temperature and level sensors. The material introduced, by decanting, when passing the septum of separation that does not reach the roof of the deposit, passes to the second compartment. This second compartment has the same number of sensors and a second screw to extract the product once the process is finished.
    [0097]
    [0098] This second compartment is heated by an indoor serpentine fed by solar panels and, if necessary, by an electric accumulator. The temperature will remain stable between 50 and 60 ° C. Polyester digesters can have a volume from 10 to 60 m3.
    [0099]
    [0100] Start-up and operation of the digester is as follows:
    [0101]
    [0102] We proceed to introduce about 300 liters of water, bacterial cultures are added and, from that moment, the introduction of organic matter from the system begins. The production is continuous and adapts to fluctuations in temperature and Ph as well as to the remains of antibiotics that can remain in the organic matter introduced.
    [0103]
    [0104] After this initial filling, when the level sensors detect that both compartments are full, the process of operation of the plant stops for 21 days for the fermentation to take place, and the plant stops introducing matter into the first compartment. The system remains for at least 21 days in reaction, knowing that the average time of continuous processing can vary, according to the temperatures and specific characteristics of the slurry to be treated, between 17 and 27 days.
    [0105]
    [0106] After 21 days of reaction, the amounts of water, bacterial cultures and organic matter determined through the first compartment are again introduced to convert the process into a continuous process.
    [0107]
    [0108] During this reaction process a biogas is produced, which is free of sulfur elements, which are removed with the filtered gas hood. The product obtained is a deodorized, disinfected and stabilized fertilizer, suitable for use as fertilizer ecological in the case of being approved.
    [0109]
    [0110] The described process of treatment of slurry and plant to carry out this process represent, therefore, innovations of characteristics unknown until now, reasons that together with their practical utility, provide them with sufficient grounds to obtain the privilege of exclusivity that is requested.

    [0164] Thus, as seen in Figure 1, said plant (1) essentially comprises a pit (2) or septic tank to collect slurry, where are installed an agitator (3), a level sensor (4) and an underwater pump (5) that communicates, through a conduction, with a separator (6), a compactor type in which the product is poured to separate the liquid part from the solid part.
    [0165]
    [0166] Following the separator (6), a first tank (7) is provided in which the pre-treatment of the liquid part which is fiber, of two cubic meters, with butterfly valve (8) or electrovalve, a sprayer (9) for cleaning with water, preferably from the system itself through a conduit that communicates with the treated water tank (24) described below, counting, also with a level sensor (4). ), element that all deposits have.
    [0167]
    [0168] In the outlet pipe this first tank (7) there are two dosing units (10), through which is added to the liquid product coagulant and binder, and a screw pump (11) that drives the flow to a centrifuge (12) in which solid and inorganic matter is reduced and separated solid from the remaining liquid.
    [0169]
    [0170] After the centrifuge (12), another conduit communicates with a second tank (13), also of two cubic meters, also provided with level sensor (4) and sprinkler (9) with butterfly valve (8), for cleaning with water coming from the system itself through a conduit that communicates with the treated water tank (24), where the liquid product arrives and where, through another dosing device (10), antifoam is added.
    [0171]
    [0172] After this second tank (13) there is provided a turbine pump (14) which sends the liquid to a third tank (15) which is the ozone treatment tank.
    [0173]
    [0174] As seen in the diagram of figure 2, said third tank (15) or tank of treatment, is larger, between 10 and 60 m3, and has a built-in level sensor (4) that, when it is reached the determined level, activates an ozone machine (16) which injects ozone into said tank (15) while recirculating the liquid assisted by an underwater pump (5).
    [0175]
    [0176] The ozone machine (16), as shown in figure 3, is assembled with a hood (17) provided with an extractor (18).
    [0177]
    [0178] In addition, the third tank (15) or tank of treatment also communicates, by means of the corresponding pipes, with two dosing units (10) that inject a coagulant and the other a product that regulates the pH.
    [0179]
    [0180] In Figures 1 and 2, it is observed as following the third tank (15) of treatment, the outlet conduction thereof, which incorporates a second open turbine pump (19) of greater capacity, 50 m3, for emptying , is divided into two circuits (20, 21) that form a bypass with respective butterfly valves (8), causing the product to pass through a sand filter (22), after which, by means of a three-way valve (23). ) the liquid is distributed, which is already converted into treated water, and preferably serves for irrigation, preferably being sent to a fourth tank (24) of treated water from which it can be used directly and / or recirculated for cleaning the plant in the sprinklers (9) of the different deposits.
    [0181]
    [0182] Preferably, the open turbine pump (19) of 50 m3 for emptying the third tank (15) has two motorized valves that act by sending the water to said fourth tank (24) of treated water that can be a raft for irrigation or to connect with it or with an irrigation pump (25).
    [0183]
    [0184] Optionally, this fourth tank (24), communicates, through another pump conduit (14), with the first tank (7) subsequent to the separator (6), to repeat the process again.
    [0185]
    [0186] Optionally, after the fourth tank (24) of treated water, a nanofiltration system and / or an osmosis system (26) is incorporated.
    [0187]
    [0188] Also, optionally, the fourth tank (24) incorporates an Instant Mixing Reactor (27) for the conservation of treated water in the best conditions.
    [0189] In the scheme of figure 2 the elements associated with the third tank (17) which is the treatment tank of the liquid part are appreciated in greater detail.
    [0190]
    [0191] Optionally, the plant contemplates an additional mixer tank (38) where the mixture of the coagulating and / or binding components that are added to the liquid product in its treatment stages after passing through the first tank (7) and in the centrifuge is made. (12)
    [0192]
    [0193] Finally, the plant comprises a digester (28), which can be seen schematically in figure 4, to which the solid part coming out of the separator (6) and, optionally, also the solid part obtained in the centrifuge (12), is sent. which communicates with said elements, for example by conveyor belt (not shown).
    [0194]
    [0195] For the introduction of said solids, the digester (28) has an inlet cone (29) provided inside it with a sintered screw (30).
    [0196]
    [0197] The digester (28), preferably, is a container with a volume of about 60 m3 of double chamber with insulating layer of 100 millimeters and manholes (31).
    [0198]
    [0199] In any case, the digester (28) works continuously and is where the solid material is mixed with a bacterium that causes its fermentation to convert the product into manure.
    [0200]
    [0201] For this, said digester (28) has two compartments, a first compartment (32) of entrance and a second compartment (33) of fermentation and exit, separated by a septum of decantation (34) open superiorly, so that, the second compartment (33) is filled by overflowing the material above said partition (34) after filling of the first compartment (32).
    [0202]
    [0203] In addition, the digester (28) has an extractor hood with filter (35), which extends throughout its length, which collects sulfurous gases from the fermentation and filters them allowing to obtain biogas without sulphides.
    [0204]
    [0205] Both compartments (32, 33) of the digester (28) incorporate temperature sensors and level sensors (4), so that, when it detects that they are full, the product filling stops for about 21 days for the fermentation to take place. . And once after that time, the product that has already been turned into manure is extracted through another sync (30) provided for that purpose.
    [0206]
    [0207] Preferably, the second compartment (33) is heated by an indoor serpentine (not shown) powered by solar panels (36) and, optionally, by an electric accumulator (37).
    [0208]
    [0209] Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field understands its scope and the advantages derived from it, stating that, within its essentiality, it may be carried out in other forms of realization that differ in detail from the one indicated by way of example, and to which it will also reach the protection that is sought provided it is not altered, changes or modifies its fundamental principle .
