Another electrolyzer is known for producing chlorine and alkalis of the diaphragm mix in a method comprising an aluminum kit, a cathode block and a lid. / Copyright certificate of the USSR 1 554314 /. An anode kit consists of one or several well-known anodes, for example, OFTA type, electrically fastened to a current-carrying base through contact film and screw ties. On the other hand, the anodes are placed with a gap of a few meters, designed for anoatt. The cathode Shy block is made up of several rows of karstratobrachschlok mesh cathode elements, electrically and mechanically bonded from the inside to the walls of the casing and dividing by a common passage. Dome-shaped rishka made of any material resistant to npoia ca environments. All parts of the electrolysis are tightly tightened with each other along the perimeter of the fit through the gaskets and B1 | No. foK is fed to the cathodic | 1 block of the common corse bus, and to a {mdn | in the set through a common base. The electrolyzer is equipped with lime devices for input and output of working media.

A disadvantage of the design of the known electrolysis cell is that all the cathode is electrically and mechanically tightened by welding with walls. Therefore, the failure of the cathode grid requires the entire unit to be tuned together with the casing, the service life of which greatly exceeds the usability time of the mesh cathode elements. Reuse of Kerzus is not possible. Encouraging the inner surface of the walls of the casing and gaining first ish during operation, the caustic toughness and resistance are welded to them from the inside of the 1st cathode plate 1, and, consequently, the implementation of a reliable cathode current supply. 3 result

With this connection oguayeekie pepe sashryazheniya in the famous eleggrolyzer. The disadvantage of the lime electrolyser is the presence of gaps in metal; in small numbers, which reduces the anode working top and reduces the useful removal of products from a busy production area.

The task is 8p; a good climb up of the model is to increase the output of the electrolyzer and the resulting consumption of electroreshish. This task requires that the cathode kit of the electrolyzer is supplied to the periphery with a frami of frammy, electrically connected to the cathode bus, and the B11utren Sh1 of the current supply of the cathode elements is electrically wired with the indicated current-carrying circuit, and the anode must be inserted into the gap.

The reference number in the proposed design of the electrolyzer is that the cathode set includes the 11th spherical section of the 11th current-dissipating frame, electrically connected to the center of the external yoke, and the current leads of the cathode electrodes are electrically and {wired tightly only from the peripheral current-sharing unit , and the anodes in the rows are placed only with a mounting gap.

The advantages of such a construction were that the cathode of the ®neiKi№su assembly was freed from the tradable internal electrical and mechanical crash, which were inevitable in the known electrical system and could not be installed due to eiQ Yari peMOi ax or AOL replacement. 6 result, in case of failure

The size of the additional anode in the gap with the anodes in pjn increases the electrode surface and, accordingly, the efficiency of the electrolysis. As applied to the prototype atom, the increase in power is 20 ".

In order to improve the internal circulation of the electrolyte in the electrolytic cell, the anodes of one or more displacements are superior to the anodes of other rows and placed with a large wagon (Fig. 10).

For the same purpose, one or more cathode elec- trons are completely violated with a gap of 19, dividing @ lenshty into the sealed part of the sealed part (Fig. 9/).
