Description

 The invention relates to devices for treating liquids, in particular to devices for obtaining alkaline and acidic properties in water when treating drinking water, sewage, as well as, for example, in agriculture to increase productivity, to destroy larvae of agricultural pests and helminth eggs, for disinfection (to reduce the use of detergents).

A device for water purification is known, comprising an elastic casing with water supply and removal pipes, a system of electrodes connected to a direct current source, a filtering charge and a container for its regeneration. The housing is made in the form of a truncated cone, and the electrodes in the form of a cone-shaped screw with oppositely charged surfaces of the blades and a step decreasing towards the smaller base of the cone. The filter load is placed between the auger blades, the housing is equipped with nozzles for supplying and removing the filter load, which are connected to a container for regenerating the load [1]
The known device has the following disadvantages. Due to the compaction of the filter load at the smaller base of the cone, the speed of water movement is more significant and the effectiveness of the effect of the electric field on water purification from pollution is reduced. As the step between the blades of the electrodes further increases, the effect of the electric field decreases, which leads to a decrease in the efficiency of water purification. In addition, the presence of rotating parts (auger) reduces the reliability of the device. The known device has a complex structure, since it requires a drive and regeneration of the filter load.

The closest technical solution to the invention is an electroactivator containing a housing with nozzles for supplying and removing liquid, a system of electrodes connected to a constant current source, separated by a diaphragm. The electrodes are made in the form of drums or endless tapes placed vertically on roller bearings, the latter being installed with the possibility of moving in a horizontal plane [2]
However, the known device has a complex structure and provides for the frequency of electrical treatment of solutions. This reduces processing efficiency and productivity.

 The invention is aimed at solving the technical problem of producing alkaline and acidic water in a continuous liquid stream, improving the pH of wastewater in the alkaline side (to restore the flora and fauna of water basins).

 To solve this technical problem in a known electroactivator containing a housing with nozzles for supplying and removing liquid, a system of electrodes connected to a constant current source, separated by a diaphragm, according to the invention, the electrodes are made in the form of multi-pole screws, while the surfaces of the blades of each screw have the same charge. In addition, the screws have a uniform pitch along the length, while the blades of one screw are offset relative to the other by half a step. According to the invention, the screws are cylindrical and fixedly mounted parallel to each other in a horizontal plane relative to the base of the housing, and the latter is made of dielectric material in the form of two paired half-cylinders, between which a diaphragm is placed. The diaphragm is made in the form of a porous membrane consisting of detachable sections.

The set of essential features of the claimed invention allows to achieve the following technical results:
continuity of action, due to which the productivity of electroactivation of the liquid increases.

simplicity of the design of the device;
the possibility of using it at different capacities due to the use of a different number of modules or changing the diameter of the casing in the form of two twin half-cylinders;
creating adverse conditions for the bacterial flora;
the possibility of removing salts of heavy metals and nitrates from the water into the precipitate with a change in pH (pH 6.5-9.0).

 In FIG. 1 shows a plan view of an electroactivator module; figure 2 section aa in figure 1; figure 3 section BB in figure 1.

 The electroactivator contains several modules, depending on the time spent in it of water and productivity by its quantity. The electroactivator module comprises a housing 1 made of a dielectric material in the form of two paired half cylinders, with supply pipes 2 and removal 3 of liquid, which are placed on opposite sides of the housing 1. Inside the housing 1 there is a system of electrodes connected to a direct current source (not shown). The electrodes are made in the form of fixed screws 4 and 5 of a cylindrical shape with a uniform pitch along the length, of different polarity with the same surfaces of the blades of each screw. The screws 4 and 5 are placed parallel to each other in a horizontal plane relative to the base of the housing. For uniform ordered movement of ion exchange through the diaphragm, the blades of one screw-electrode are shifted relative to the other by half a step. The housing 1 is divided into two parts using a diaphragm made in the form of a porous membrane 6, consisting of detachable sections, which allows its replacement and repair. At the same time, a negative electrode 4 is placed in one part of the housing 1, and a positive one in the other 5. The ends of the housing 1 are made in the form of flanges with a seal protrusion-cavity 7. The membrane 6 is placed in a detachable membrane frame 8, which has waterproof seals 9. The housing 1 is installed on supports 10 to the foundation plate using support legs 11 with anchor bolts.

 The shape of the electrodes in the form of screws leads to a decrease in the linear velocity of water and to an increase in turbulence in the flow. This allows for a short time to obtain uniform polarization of water and ensures the continuity of the process.

 Electroactivator works as follows.

 With the passage of water from the pipeline through the pipe 2 to the module of the electroactivator is a separation into two streams. The flow rate is slowed down by increasing the cross-sectional area of the housing 1 and changing the nature of the movement due to the influence of electrodes made in the form of screws. During the passage of fluid flows through the electroactivator at the outlet of the nozzles 3, polarized water is obtained: alkaline (pH 8.0) and acidic (pH 3.0). The number of electroactivator modules is selected depending on the water flow rate and the degree of its saturation with dissolved chemical elements. The degree of polarization of water, depending on the conditions for its further use, will depend on the regulation of voltage and current in the time factor and the constancy of water flow.
