Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] As shown in the accompanying drawings, the electrolytic cell of the present invention includes an alkali solution chamber, an anode chamber and an oxygen chamber. An electrolytic cell for electrolysis, comprising electrolytic cell casings 1 and 11, the two casings are sealed and fixed through external iron plates with holes, and the material of the electrolytic cell casing is preferably graphite, which has good conductivity. An air outlet pipe 14 and a lye outlet pipe 15 are arranged on the top of the electrolyzer shell 1, 11, and an air inlet pipe 12 and an lye inlet pipe 13 are arranged on the bottom of the outer wall of the electrolyzer shell 1,11. The oxygen chamber is mainly surrounded by the shell 1 and the oxygen cathode carrier 3. The material of the oxygen cathode carrier 2 is preferably nickel foam, which has a very good pore structure and is...

Abstract

The invention relates to a universal electrolytic bath for electrolysis. The universal electrolytic bath comprises a shell, an oxygen chamber, an anode chamber and an alkali liquor chamber, wherein the shell is a bracket of the electrolytic bath and consists of two parts. The anode chamber includes a shell and an anode. A graphite strip and a gas-liquid separation chamber are also arranged in the chamber; and a NaCl inlet pipe and a chlorine outlet pipe are also arranged on the side edge of the shell of the electrolytic bath. The oxygen chamber comprises a shell and an oxygen cathode carrier, and a current collector is further arranged in the oxygen chamber. An air inlet pipe is arranged at the upper part of the oxygen chamber, and an air outlet pipe is arranged at the lower part of the oxygen chamber. The alkali liquor chamber comprises an oxygen cathode carrier, an ionic membrane and a shell. An alkali liquor inlet pipe is arranged at the upper part of the alkali liquor chamber, and an alkali liquor outlet pipe is arranged at the lower part of the alkali liquor chamber. The electrolytic bath is simple in structure, small in occupied area and low in operation cost.

Description

technical field [0001] The invention relates to the field of electrolysis, in particular to the design of a universal electrolyzer. Background technique [0002] Electrolysis is widely used in industrial production, such as sewage treatment, metallurgical industry and chlor-alkali industry. At present, ionic membrane electrolysis has the most mature and economical production technology at this stage. Moreover, the electrolytic cell has the advantages of small equipment footprint, continuous production, large production capacity, high product quality and purity, low energy consumption, and low pollution, so continuous optimization of the electrolytic cell has become a necessity. Taking the electrolysis of sodium chloride as an example, the use of this new type of electrolytic cell is introduced. The chlor-alkali industry is one of the most basic chemical industries, and its product caustic soda is widely used in the chemical industry. The general electrolysis of salt water...
