Description

 The invention relates to electrochemical unipolar processing of liquid media, allowing to give these media widely adjustable stable and metastable properties of solutions, which can be used in various fields of human activity, while reducing the environmental burden on nature.

 In particular, this technical solution relates to batch installations for improving the quality of drinking water and for obtaining various solutions for sanitary and domestic needs, for presowing seed treatment, processing vegetables and fruits before laying them for storage and for treating animals.

 A known installation for the electrochemical treatment of water (1), containing a rectangular casing of dielectric material, divided by a vertical porous diaphragm into two chambers, each of which contains vertical graphite electrodes connected to a direct current source. The housing is mounted on the hinged wall of the case, in the upper part of which a DC source is mounted.

 The disadvantages of this device are the uneven processing of the entire volume of liquid and the inconvenience of draining the solution from the device.

 This device is adopted as a prototype.

 The aim of the invention is to remedy these disadvantages.

 This goal is achieved by the fact that in the device for the electrochemical treatment of aqueous solutions, including a rectangular case with a container of dielectric material, divided by a central partition into two chambers in which a cathode and an insoluble cylindrical anode are connected, connected to a constant current source, the electrodes are installed in a horizontal position in the lower part of the housing, and above each electrode there are additional inclined partitions of non-conductive material that separate the sunrise treated liquid effluent from untreated. The central partition has an insert in the form of a porous diaphragm at the level of the location of the electrodes.

 In addition, a hole is made in the central partition at the level of filling the container with liquid, in which an additional mesh electrode is mounted connected to the negative terminal of the power source.

In FIG. 1 shows the design of the proposed device, side view;
in FIG. 2 - the same, top view;
in FIG. 3 shows a sectional view of the device.

 The device consists of a rectangular case 1 with a cover 2 and a handle 3, on which a limit switch 4 and a timer 5 are located. The case is mounted on the base 6, in which a direct current source 7 and a contact pair 8 are located, which interacts with a response contact pair on the case 1. In the base 6 there is a socket for attaching a power cord 9.

 In the upper part of the housing 1 there are two drain channels 10.

 Inside the housing 1 there is a central partition 11 of non-conductive material, at the bottom of which there is an insert in the form of a porous diaphragm 12.

 Above the horizontally mounted electrodes 13 and 14, two additional guide inclined partitions 15 of non-conductive material are installed, separating the flow of treated liquid from the untreated ascending due to gas lift.

 An opening 16 is made in the central partition 11 at the level of filling the container with liquid, in which an additional mesh electrode 17 is installed, connected to the negative contact of the power source.

 The operation of the device is as follows.

 The container 1 is filled with water, for example, tap water with the cover open 2. The container is installed on the base 6, and through the contact pair 8 the power is turned on if the cover 2 is closed. At the same time, the limit switch 4 turns on the timer 5 with a predetermined exposure and power to the electrodes 13 and 14.

 During operation, the liquid rises under the action of the released bubbles on the electrodes 13 and 14, freeing up space for the untreated liquid.

 Due to the electroosmotic flow through the porous diaphragm 12, the liquid level in the cathode chamber rises and part of the liquid flows into the anode chamber through the hole 16. Due to the charge on the mesh electrode 17, positive ions are discharged and thus do not reduce the number of negative ions in the anode chamber.

Industrial applicability
The manufacturing technology of fairly simple parts of the device is well known and does not present any difficulties.
