    Irrigation system and procedure for hydroponic crops. Irrigation system for hydroponic crops, of which are carried out in culture tanks (1) containing a nutrient solution, formed by a framework (2) partially submerged in the nutrient solution of the culture tank (1), being formed said network (2) by straight channels (3) spaced apart by adjacent cells (4) where the plants to be cultivated are arranged, said cells being connected with said channels (3) and/or with each other; and where the channels (3) have an inverted u-shaped cross section. The system comprises at least one irrigation emitter (5) arranged in a channel (3) of the framework, said emitter (5) being configured to emit a flow of nutritive solution in the nutrient solution contained in the tank (1) or on the surface (10) thereof. The invention also relates to the irrigation process. (Machine-translation by Google Translate, not legally binding)

    drainage pipes (7) (figure 1A) or to a nutrient solution storage tank (9) (Figure 1B) and, on the other hand, to the irrigation emitters (5).
    As can be seen in figure 1, the system includes overflows (8) by
    5 where the excess nutrient solution comes out or overflows from the culture tank that is led to the irrigation head or to the storage tank (9) through the drainage pipes (7), thus maintaining the same volume of nutrient solution in the culture tank (1). The storage tank (9) allows the drained nutrient solution to be stored before being recirculated back to the culture tank (1).
    10 Figure 2 shows in detail the fabric (2) formed by a series of straight channels (3), said channels (3) being spaced apart by a set of cells (4), said cells (4) being able to be communicated with the straight channels (3) and / or intercommunicated with each other.
    Said framework (2) may be attached to the culture tank (1) fixedly at the bottom of the culture tank (1) or to the sides thereof. Also, the fabric (2) can be glued to the bottom of the culture tank (1) or simply supported on it. On the contrary, the fabric (2) can be made in a mobile way, by arranging it floating,
    20 always keeping a part of the submerged framework and another emerging part on the surface (10) of the nutrient solution contained in the culture tank (1). In this case, the system would include floating bodies (11) that have the function of regulating the buoyancy of the fabric (2). These bodies (11) would be located in the spaces formed between cells (4) and between cells (4) and longitudinal channels (3)
    25 (see figure 2).
    Preferably the floating bodies (11) are made of polystyrene; They can also be made of plastics such as polyethylene, polypropylene, PVC and can be filled with polystyrene, air or polyurethane foam among others. Bliss
    The buoyancy is calculated based on the weight of the fabric (2) as well as the weight of pipes and crops that the fabric (2) had to support. The framework itself (2) can also be part of the structures designed to control buoyancy and can be made of the same materials as the floating bodies (11).

    As shown in Figure 3, each longitudinal channel (3) has an inverted U-shaped cross section, being composed of an upper plane (12) parallel to the surface (10) of the nutrient solution contained in the tank culture (1) and on two sides or side walls (13) perpendicular to the surface (10) of the
    5 nutritive solution or containing at least one longitudinal plane (P) perpendicular to said surface (10), thus forming a channel structure (3) with an inverted U-shaped cross section. Preferably, the distance between the lateral walls (13) of the channels is between 10mm and 200mm, thus optimizing the space for plant cultivation.
    10 The cross section of the side walls (13) can be rectangular or trapezoidal (as is the case shown in Figure 3), but they will always include at least one longitudinal plane (P) perpendicular to the surface (10) of the nutrient solution contained in the tank (1).
    The side walls (13) of the channels (3) comprise openings (14) that communicate said channel with the adjacent cells (4), as observed, for example, in Figures 2, 3 and 5.
    20 For its part, as shown in Figure 4, the adjacent cells (4) are formed by side walls (15) that form their perimeter and structure. Said side walls (15) have openings (16) through which the cells (4) communicate with the channels (3) and / or each other.
    25 Like the side walls (13) of the channels (3), the cross section of the side walls (15) of the cells (4) can be rectangular or trapezoidal but will include a longitudinal plane perpendicular to the surface (10) of the nutrient solution contained in the tank (1).
    The channels (3) and cells (4) can be made of any rigid or semi-flexible plastic, for example, polypropylene, PVC or polyethylene or as described above, with floating materials. They can also be manufactured by means of molds or through the union of different pieces by gluing or articulation.
    35 Each channel (3) can receive one or more irrigation emitters (5) along its route. There may also be channels that do not include any irrigation emitter. The

    The irrigation emitters (5) can be installed in all or several longitudinal channels (5) of the system. For the preferred ranges of flow rate and dynamic pressure in the above-mentioned irrigation emitter (5), preferably the irrigation emitters will be spaced within the same channel between 25 cm and 450 cm (in case
    5, more than one are installed in the same channel) and preferably they are spaced laterally (distance between transmitters located in adjacent channels) between 10 cm and 600 cm.
    The transmitters can be arranged in different channels forming triangles with each other
    10 "tresbolillo", forming squares, facing each other to regular spaces in width and length, or in rectangular arrangement.
    In order to carry out the hydroponic irrigation process by means of the described system, first of all the irrigation emitters (5) are fed by pipes or
    15 pipes (18) located on the sides and / or fronts of the culture tank (1).
    A given flow rate is delivered at a given pressure to be projected by the irrigation emitters (5) in the nutrient solution or against the surface (10) of the liquid (nutritive solution) contained in the culture tank (1) with an inclination between 0º and 80º
    20 the degree 0 being parallel to the line formed by the surface of the liquid (10) contained in the culture tank. This impact generates a high level of oxygenation, significantly improving plant health and the quality of the liquid contained in the culture tank.
    25 As mentioned previously, the irrigation emitters (5) preferably emit a flow rate between 15 liters / hour and 600 liters / hour at a working pressure between 0.15 kg / cm2 and 6 kg / cm2 during the irrigation procedure
    As shown in Figure 8, the flow rate emitted at the given pressure, once
    30 impacts on the nutrient solution contained in the culture tank (1), generates a main stream (19) that runs in the direction of the channels (3). Said main current (19) generates, in turn, secondary currents (20 and 21) being in the exposed case a secondary absorption current (20) that circulates through the openings (14) that are arranged between the straight channel ( 3) and
    35 adjacent cells (4). This secondary absorption current (23) also generates additional dispersion currents through the openings (16) that
