Description

one

The invention relates to the design of electrocoagulators for the separation of dispersed systems, as well as for the purification and disinfection of natural and waste waters.

A electro-coagulant is known, consisting of a body and parallel plates placed inside it, which are electrodes 1.

The disadvantage of this electrocoagulant is the low degree of purification of disperse systems from suspension.

Also known is an electrocoagulant for processing disperse systems, consisting of a body and a set of electrodes parallel to each other and two pairs of perforated plates arranged on both sides of the set and perpendicular to the electrodes, these plates serve as flow distributors for the treated liquid 2.

However, such an electrocoagulant has a significant processing time and a low degree of purification.

The purpose of the invention is to reduce the processing time and increase the degree of purification.

This is achieved in an electrocoagulator consisting of a body with a set of electrodes parallel to each other and two pairs of perforated plates placed perpendicularly placed in it.

electrodes on both sides, and each of the two perforated plates closest to the electrode set is connected to electrodes of one polarity, and each of the two perforated nlastin distant from the electrode set serves as an electrode of opposite polarity to the plates adjacent to the set.

In the drawing, "the proposed electrocoagulant is rendered.

The electrocoagulator consists of a housing 1 with inlet and outlet nozzles 2 and 3 with dielectric pads 4, a set of electrodes 5 parallel to each other, made, for example, of aluminum, perforated plates 6 made of iron and connected to the same floor electrodes electrode set, two remote from the set and parallel closest to the set of perforated plates 7, serving as electrodes and made of iron.

Electrocoagulant works as follows.

The initial water is supplied to the housing 1 through the inlet latruck 2, through the perforated plates 7, which are electrodes, and the perforated plates 6, the water is distributed evenly throughout the electrocoagulant volume. Through the terminals, the main electrodes 5 and the additional electrodes are energized. When dissolving the anodes of the set of electrodes 5 and perforated lastin, which are anodes, coagulant is formed from iron and aluminum hydroxides. The treated liquid is then discharged from the electrocoagulant through pipe 3 and fed to the settling beds.

When using perforated plates separating the stream of treated water, a complex electric field of the non-uniform field-uniform field-non-uniform field is created as electrodes. This field, created by electrodes made of different materials, makes it possible to obtain particles with an increased specific gravity and coagulation abilities (ohm. Table) when these electrodes dissolve.

Thus, in the proposed electrocoagulator, the processing time is reduced and the degree of purification increases.
