Abstract

Diaphragm electrolyzer, including a housing with an anode chamber with an anode electrode and a cathode chamber with a cathode electrode placed in it, the chambers being separated from each other by a diaphragm made permeable to ions, but hindering mechanical mixing, characterized in that the diaphragm is made of tarpaulin.

Description

. Diaphragm electrolyzer

The invention relates to devices for producing compounds or non-metals and metals by electrolytic methods, and in particular, for producing alkaline or acidic water from tap water.

Depending on the purpose of the process, in which diaphragm electrolyzers are used, the diaphragms can be made of various materials.

A well-known electrolyzer for electrochemical treatment of water, including a stainless steel tank, stainless steel electrodes, diaphragms made of filter cloth (see the book: V. M. Rogova, V. L. Filinchuk Electro-chemical technology for changing the properties of water, Lviv, publishing house Higher School, 1989, p. 77-78, Fig. 4. 4). The closest in combination of features (prototype) is a diaphragm electrolyzer, comprising a housing with an anode chamber with an anode electrode and a cathode chamber with a cathode electrode placed in it, the chambers being separated from each other by a diaphragm made permeable to ions, but complicating mechanical mixing (see Description of the invention to the patent of the Russian Federation N 2140881 IPC6 C02F1 / 461.9 / 00; C25C7 / 00; C25B9 / 00). This design of the electrolyzer, especially for the production of alkaline or acid water from tap water, has a limited number of types of material that can be used to make a diaphragm. The proposed utility model solves the problem of expanding the types of material used to manufacture the diaphragms of electrolyzers. To achieve this technical result in a known diaphragm electrolyzer, comprising a housing with an anode chamber with an anode electrode and a cathode chamber with a cathode electrode placed therein, where the chambers are separated from each other by a di: af, rgma made permeable to ions, but making mechanical mixing difficult , new is that the diaphragm is made of tarpaulin.

The proposed utility model allows you to expand the types of materials used for the manufacture of diaphragms of electrolytic cells, as well as reduce the cost of diaphragm electrolytic cells.

The proposed utility model is illustrated in the drawing, which schematically shows a diaphragm electrolyzer.

The cell contains a box-shaped body 1, which is divided by two diaphragm 2: into the anode chamber 3, in which the anode electrode 4 is placed, and the cathode chamber 5, in which the cathode electrode 6 is placed. The anode chamber 3 has a supply pipe 7 for supply; into the chamber of tap water (valves are not shown in the drawing) and a discharge pipe 8 for draining the anode (acidic) water. The cathode chamber 5 has a supply pipe 9 for supplying tap water to the chamber and a discharge pipe 10 for discharging the cathode (alkaline) water. The diaphragm 2 is made of tarpaulin.

The electrolyzer operates as follows. An electric current is supplied to electrodes 4 and 6 and electrolysis begins in the electrolyzer filled with tap water. Canvas diaphragm 2 does not interfere with the passage of positive and negative ions formed in the water, but prevents the mechanical mixing of alkaline and acidic water. After reaching the required water parameters, it is discharged through pipelines 8 and 10. After the supply of electric current to the electrodes 4 and 6 is stopped, the tarpaulin diaphragm prevents the mechanical mixing of alkaline and acidic water.

The proposed utility model expands the types of materials used for the manufacture of diaphragms of electrolyzers, and also allows to reduce the cost of diaphragm electrolyzers.
