DEVICE FOR CLEANING AN OX

The utility model relates to the electrochemical purification of water from salts of potassium salts, iron and other harmful impurities.

Scope - purification and disinfect1: natural water projection for drinking water supply, food and pharmaceutical industries, as well as in the power system for softening and deferrization of 4Hoii water supplied for boilers and other heat power plants.

Known electrolyzer (1), comprising a housing, anode and cathode chambers with an anode and cathode, where a diode is installed on the anode line to rectify the alternating current, creating a pulsating direct current.

The resulting alkaline and acidic water merges into separate containers. Covers from waterproof are put on the anode and cathode; Tissues with the purpose of preventing the detachment of salts at the cathode and the output of the decomposition products of the anode into water.

The disadvantage of this electrolyzer are:

-periodic change of covers from the anode and cathode for cleaning;

- all hardness salts in an enlarged form are removed from the cathode. chambers with water, i.e. water is practically not purified;

- acid water from hardness salts is not purified according to the conditions of ele: chtrolysis and is ballast;

- as drinking water, sour and alkaline to drink, the permits of the Ministry of Health do not have PQ.

Therefore, for drinking water supply, food industry and pharmaceutical industry, water obtained using the described technology without further purification is unsuitable.

The proposed utility model eliminates these disadvantages and allows you to get neutral purified water with no waste in the form of :: islo: 1 water.

This is achieved by the fact that after the electrolyzer, the anolyte and catholyte are sent to the mixer, where alkaline G deactivation occurs. and 1 acid: 1 water C). After the mixer, water with suspended solo particles:, of hardness, passes through a mechanical bulk filter and, freed from suspensions, is sent to the consumer.

The cathode is the electrolyzer body, and the anode is a graphite rod, which 11 is an inert anode, i.e. in the process of electrolysis; NC dissolves (3).

and 1 / GG r anti-scale device APU-OOI. To obtain the maximum amount of purified water, the ratio of water passing through the anode and cathode chambers is 1:10, which is the optimal mode of the water electrodialysis process when cleaning it from hardness salts and muds, inen, and iron (4). Ka $ ig. 1 is shown in general; view of the device, Fig. and - electrolyzer, vertical section. The device (FIG. 1) consists of an electrolyzer 1, a mixer-deactivator 2, a mechanical bulk filter 3, control valves 4. The electrolyzer (figure 2) consists of a housing 1, which is a tube and is a cathode, graphite rod 2 is an anode, dividing screen 3 from the ion exchange membrane i / lAK-l, acoustic anti-scale device 4, insulators 5, flange b, stuffing box with thrust ring 7, sealing cone 8, sealing sleeve 9, thrust bearing 10 and conical sealing sleeve I. The electrolyzer has an entrance waters anodic; channel a and cathode channel k. The device operates as follows. Water is supplied to the electrolyzer 1 through channels a and k in a ratio of 1:10. Passing through the electrolyzer, water is exposed to direct electric current and decomposes with the formation of OH ions in the cathode chamber and coagulation of CaO hardness salts, and others, and in the anode chamber with the formation of NO, where coagulation of hardness salts does not occur. Water taken from the cathode space is saturated with OH ions and has a strongly alkaline reaction. Water taken from the anode space is a solution of hydrogen ions, i.e. oxonium H-O and has an acid reaction (2). After electrolyzer 1, the anolyte and catholyte enter the mixer 2, where acid and alkaline water are deactivated. Further, neutral water СРН) passes through a mechanical bulk filter 3 and, having freed itself from suspensions of salts and hardness contained in it, is sent to the consumer.
