    DESCRIPTION

    Filter for the purification of large water flows.

    Object of the invention 5

    The object of the present invention is a filter for the purification of large water flows, which has characteristics aimed at achieving a low life cycle cost (manufacturing, operation and recycling), the possibility of having a variety of models and sizes, the filtering of large quantities of water 10 using a single filter unit and a periodic regeneration of the filtering capacity automatically and with a reduced expense of the amount of water used in the regeneration.

    Field of application of the invention

    This invention is applicable in the field of purification of all types of water with low and medium pollutant loads and mainly large water flows, such as swimming pools, lagoons, ponds or the like.
     twenty
    State of the art

    Different types of water filters are currently known for these types of applications:
     25
    a) Water filters with polyester container:

    These filters have a free, vertical or horizontal shape, of any size and a filtration surface corresponding to their area or section.
     30
    These filters with a polyester container are cheaper than the filters with a steel container, and house inside them a filter medium that can be flint sand or recycled glass-glass. Water enters through the top of the container and passes through the filter medium to finally reach some final elements, which
    installed inside the filter media (called crepins, collecting tubes, among other names) with openings or openings smaller than the granulometry of the filter media, allowing the passage of filtered water, but not the particles of said filter media finally leaving filtered water collected from the bottom of the container. 5

    The speed of water passing through the inside of the filter to achieve good filtration quality varies depending on the use of the water and the regulations that affect each case, being a speed suitable for most uses of 30 m3 / hour per Each square meter of filtration area. 10
    In the case of using flint sand, particles larger than 20 microns are retained in the filter medium. In the case of using glass the retained particles are those with sizes greater than between 1 and 5 microns.
     fifteen
    These filters require approximately one cleaning per week, reversing the water flow cycle and for approximately 7 minutes the water enters below and leaves the dirt above to a drain, with the consequent loss of this water.
     twenty
    Flint sand must be replaced every 3-5 years and the filter glass does not need to be changed.

    In a practical case, using a filter of this type, with a diameter of 2000 mm, a filtration area of 3.14m2 and a filtration rate of 30m3 / h / m2, 25 94.2 m3 / hour of water are obtained filtered.

    Therefore, with this flow, a weekly cleaning of 7 minutes means 11 m3 of water lost to the drain, every week.
     30
    The polyester filter of flint or glass filter media has certain advantages such as: a low cost and diversity of models and sizes, and some inconveniences such as: a lot of water loss in its cleaning; it is necessary to use numerous units for use in large water flows, for example to filter 450
    m3 / h five filters of 2000 mm are needed. and there is a loss of water by drain in the cleaning of 220 m3 of water per month.

    b) Steel filters with perlite regenerative filter medium:
      5
    These filters are much more expensive than a polyester filter and have a vertical circular shape with limited sizes due to their main characteristic of having the mobile top and housing a mobile roof inside which hundreds of flexible pipes, or hoses, are formed. by a stainless steel base and covered with polyester mesh that support the regenerative filter medium, called perlite, and give the filter a large filtration surface, allowing it to work at low water flow rates with large flow rates.

    Water enters through the lower part of the filter and exits through the upper part after passing through the perlite filter medium and through the flexible tubes, retaining in its interior all dirt greater than 1 to 5 microns.

    The useful filtering surface goes from being the area of the sand filter section perpendicular to the water flow, to be the area formed by the perlite that adheres to the hundreds of filter tubes. twenty

    The movable roof of its interior has a pneumatic system, called Bump or Bumping due to its action of being able to move, raise and lower inside the filter.

    This up and down movement is used to regenerate the perlite that needs to be removed approximately every 4 hours and renewed approximately once a month.

    When moving the inner ceiling with the hundreds of flexible tubes hanging, the perlite is detached from these flexible tubes. This movement of raising and lowering the movable roof 30 makes a cleaning, regeneration of the perlite, which allows it to be used for approximately one month; after this time it is necessary to empty the filter through its drain to remove the used perlite and clean the flexible tubes.

    The monthly cleaning of the filter, even if chemical products are used to automatically enter inside the filter, additionally requires manual cleaning to leave the flexible tubes perfectly clean. This cleaning is done by disassembling a front window of the filter and projecting pressurized water against the flexible tubes; using the rotating movable ceiling of the filter to face 5 successively all the tubes with the window and that they are clean.

    The cleaning of the hoses with pressurized water and the subsequent rinsing of the inside of the filter supposes the discharge by the drain, and consequently the loss, of about 20 m3 of water per month. 10

    A steel filter with flexible tubes and regenerative medium of perlite can have up to 150 m2 filtration surfaces and work at low water flow rates, about 3 m3 / hour per square meter of filter surface, which makes With a single filter, a flow rate of about 450 m3 / hour of filtered water can be obtained.

    150 m2 x 3m3 / hour / m2 = 450 m3 / hour filtered by a single filter with a housing diameter of less than 1,600 mm.
     twenty
    These steel filters with regenerative filter medium of perlite have the following advantages: a single unit of for example 1,600 mm. can filter large water flows, up to 450m3 / h .; The monthly cleaning spends very little water, only about 20 m3. And at the same time present the following disadvantages: it needs to be made of steel because of its movable roof and this makes it have a high cost; sizes limited by 25 mechanical characteristics (movable roof) and need to have records and removable elements; and the necessary monthly manual cleaning is difficult and laborious and must be carried out by trained personnel.

    Description of the invention 30

    The filter for the purification of large water flows object of the invention has characteristics aimed at solving the problems of
    cited background and to obtain the advantages provided by them; specifically:

    - Low cost
    - Possibility of having diversity of models and sizes 5
    - That a single unit can filter large water flows
    - Monthly cleaning using little water and that this is done automatically, not manually and without the need for personnel to be specially trained.
     10
    With these objectives the filter of the invention has a polyester structure, in order to allow a variety of shapes and sizes at low cost.

    For this, a fixed structure will be available without moving parts and without a mobile roof, with a large filtration area and a regenerative filter medium that is perlite. fifteen

    This filter comprises at least:

    - a polyester tank with a lower part and an upper part separated by a fixed separating roof; twenty
    - a water inlet and distribution manifold arranged at the bottom of the tank, with the water outlets facing down, and connected to a water inlet;
    - a lower drain with a valve to remove dirt during filter cleaning; 25
    - a cleaning device comprising a cleaning manifold, arranged above the water inlet and distribution manifold, consisting of a ring of tubes with small jets oriented towards the upper area of the filter, said cleaning manifold being connected to means of injecting fluid under pressure during the cleaning phases thereof;
    - a plurality of flexible tubes attached to the fixed separator ceiling and suspended therefrom, said tubes forming a support for the perlite filter medium;
    - a manhole for the assembly and maintenance of interior components;
    - an upper outlet and air vent provided on one side of some air detecting sensors connected to a control panel and on the other of an opening and closing valve for air evacuation, automatically commanded 5 by the control panel depending on the signals provided by the probes and;
    - a superior outlet of filtered water.

    In one embodiment of the invention, the fixed partition ceiling is made of reinforced polyester.

    The water inlet and distribution manifold is oriented downwards, that is to say towards the lower end of the filter, so that the incoming water does not go strongly towards the flexible tubes, or hoses, of the support of the pearlite 15

    The pressurized fluid delivery means to the cleaning manifold comprise an air source for the introduction of air during the regeneration of the pearlite, which is carried out with a certain frequency, approximately 4 hours, and during an initial phase of cleaning. monthly filter, and a high pressure pump 20 to introduce pressurized water during a final phase of the monthly cleaning, to finish the cleaning of the hoses.

    The flexible tubes comprise an inner stiffening element covered by a mesh of braided fibers of polyester, carbon fiber or other equivalent material 25 that serves as support and retention of the filter medium, perlite.

    The number of flexible tubes will depend on the amount of water that you want to filter, and it is unlimited and can be around 1000 flexible tubes.
     30
     As mentioned, the opening and closing valve for the evacuation of air is automatically commanded by the control panel based on the signals provided by the probes to said control panel, which allows said valve to open automatically when the probes detect the presence of
    air and that they close when they detect the presence of water, thus ensuring that the filter is kept full of water.

    With the characteristics described, the filter works as explained below:
     5
    Unfiltered or prefiltered water by another device enters through the bottom of the filter, passes through the perlite and the flexible tubes and exits through the upper outlet of already filtered water.

    To regenerate the perlite, approximately every 4 hours, the control panel automatically activates the air production source for a few minutes, causing the perlite to detach from the flexible support tubes.

    The upper valve removes the filter air during the regeneration cycle and / or later. fifteen

    The monthly cleaning of the filter is done effortlessly with the automatic use of the air source and the pressure water pump with fixed and mobile nozzles, which allows reducing the amount of water used in cleaning, compared to the manual systems currently used. twenty
