Electrogiaoagulator for wastewater treatment

The invention relates to equipment for wastewater treatment by the electrochemical method. I can use the co-alignment of electrocoagulators for the purification of industrial wastewater from galvanic, chemical and other industries from ions, metal drains, oil products, surfactants and other pollutants

A known apparatus for cleaning greed I. containing a cylindrical sump with an electro-agitator chamber placed in it with an electrode block “the upper part of which is made in the form of a truncated cone facing up with the smaller base, and the lower part is made in the form of a cone facing up with the large base up it is axial, and the input nozzle is located tangentially with respect to the cone, and a shower head is installed above the electrodes, connected to the input nozzle of the initial liquid.

The design disadvantage is the insufficient length of the electrode gap of the electrode unit and the complexity of its switching.

The device does not provide efficient use of the coagulant and the electrolyte mixture in the scattering stream of the liquid being cleaned, which leads to incomplete binding of contaminants in the coagulant process and increased energy consumption,

Closer in technical essence to the proposed device is a continuous olactrocoagulant for cleaning charged liquid 2, which includes a vertically located chamber with cylindrical electrodes concentrically mounted in it with variable gaps increasing to the periphery, pipes of contaminated and purified liquids.

- 2 periodic replacements. the short contact time of the liquid to be cleaned with the electrodes, as well as the rapid introduction of the foam product from the interelectrode gaps and, as a consequence, the need to use electrolitp for cleaning, “the efficiency of using the electrode unit is insufficient, the depth of liquid cleaning is insufficient, practice shows that the known devices L and 2 provide liquid cleaning PGI concentrations of pollutants not higher than 1ShG / L,

The claimed technical solution is aimed at increasing the efficiency of wastewater treatment, ensuring the cleaning of an increased concentration of pollutants, reducing operational g outcomes. This is achieved by the fact that in the electrocoagulator, see and an irradiation chamber with electrodes located in it: the same as the input lead f f / electrodes, the helix with the electrical wires on one of the ends are stopped between the disks resting on the ends of the spirals through an elastic insulating layer, forming my electrode gaps - a gap cavities converging from the periphery to the center. where the outlet pipe for purified liquid and gases is installed. The long-term presence of the liquid being cleaned in the electric field is interelectro -. cavity enhances electrolysis.

on phage, 2 - arrangement of spirals.

The electric coagulator consists of a casing with an inlet pipe 2 i “outlet casing 3, on the threaded part of which a perforated sleeve 4 is screwed on placed on not: -: lower bright nb, spiral electrodes C and 7 with gaskets 3, upper cover 9f with glass 10, which secured with nuts N

the periphery enters the interealatrode cavities formed by helical electrodes, where the 6-anode is the 7-cathode, the code moves the wastewater to the center of the Odesoda, where through the hole in the “sleeve 4, the liquid enters the inner channel and exits through the outlet pipe further processing.

In the process of passing through the electrode cavities in the liquid to be cleaned, alentro-chemical processes occur: dissolution of the asweal of the anode, ionic solution of the solution, evolution of the dissolving and usurper:; hydroxides in coagulants, the weight of these processes take place completely in the electric power supply floor and sting "no.ecffu owing to which the most common shelf phase-dispersed conversion Water purification I zgenzhene Tsih impurities During the cleaning process, part of the “nn” rises in the next-electrode space, where the delay in the amount of liquid coming to the treatment and subsequent removal of the pole and foam are reduced. Hydrogen released through the processed electrochemical hydrogen stream through 2 and step I) enters the atmosphere

On a small 2-stage installation with productivity

wastewater treatment was carried out with copper and steel soda) g / l. Nchhl ocyastyaa: current 1Sh yaapsivens 5th. The residual water content of the specified metals a exceeded A elg / l

It is therefore possible to ensure such a large supply of large expenses for the provision of deep wastewater treatment, including with a large number of newly introduced substances. more than permissible for electro-agglomeration on existing appatati in 5-1Eraz "
