DEVICE FOR GAS-FLAME PROCESSING OF MATERIALS Russian patent published in 2009 - IPC B23K5/22 B23K7/10 C25B1/06 

FIELD: mechanics; tools.

SUBSTANCE: tank with electrolyte is installed above bipolar electrolytic cell. It consists of electrodes in the form of metal plates separated by elastic gaskets with creation of electrolytic cells (EC). In the first plate window is provided for electrolyte, in the last one - opening for gas mixture. In plates of other EC openings are provided for electrolyte and openings for gas mixture. Electrolytic cell has inbuilt facility of electrolyte supply (ESF) in cells with elastic elements with round through opening and communicated by blind channel. Electrolytic cell with inbuilt elastic elements is fixed with tension in clamping frame between end inserts, with preliminary pressing of elastic gaskets, and with provision of pressing of every elastic element of ESF between two plates of appropriate cell. Windows that are accordingly arranged in the first and last plates of the first and last cells have rectilinear upper facets, which are located at the same level for setting of electrolyte level. Ratio of elastic element through hole cross section to area of cross section of blind channel is within the limits of 10-20. Tank with electrolyte is located above electrolytic cell and simultaneously serves as moisture separator, for this purpose window for exhaust of gas mixture in the last cell of electrolytic cell communicated to upper gas section of mentioned tank via gas-removing hole of insert and via exhaust opening of hole. Hydraulic lock is installed downstream electrolyte tank, and its input communicates to output of this tank gas section, and output of hydraulic lock communicates with inlet of facility for supply of gas to burner.

EFFECT: improved reliability, stability and efficiency of electrolysis, possibility to control composition of gas mixture and increased fire and explosion safety.
