Abstract

The present application discloses an electrolytic dehydrogenation device and an integrated cabinet-type large-scale chlorine brine type sodium hypochlorite generator, wherein the electrolytic dehydrogenation device includes a separation tank, and the separation tank is respectively connected with a liquid inlet pipe located on the peripheral wall of the separation tank, and a liquid inlet pipe located in the separation tank. The liquid outlet pipe in the middle of the bottom wall and the air outlet pipe located in the upper part of the separation tank; the bottom wall of the separation tank is fixedly connected with a separation plate arranged along its axial direction, the projection of the separation plate on the bottom wall of the separation tank is vortex shape, and the separation plate The end of the outer ring is fixedly connected with the inner wall of the separation tank, and the end of the inner ring surrounds the peripheral side of the connecting part between the liquid outlet pipe and the separation tank; an arc-shaped channel is formed between the outer ring of the separation plate and the inner wall of the separation tank, and the liquid inlet direction of the liquid inlet pipe is related to the arc. The shaped channel is tangent to and oriented to the helical direction of the separation plate. The present application has the effects of high hydrogen removal efficiency, simple overall structure, almost no loss in operation and low maintenance cost.

Description

technical field [0001] The present application relates to the field of electrolytic hydrogen production, in particular to an electrolytic hydrogen removal device and an integrated cabinet type sodium hypochlorite generator for large production of chlorine brine. Background technique [0002] Sodium hypochlorite is a strong oxidant with strong bactericidal and bleaching effects. It is the most widely used disinfectant at present. It is mainly used for disinfection in food processing enterprises, water treatment in circulating water systems of nuclear power plants or thermal power plants, and sewage in petrochemical or printing and dyeing enterprises. And circulating water treatment, domestic water supply disinfection, hospital or urban sewage treatment and disinfection projects. Sodium hypochlorite is mainly prepared by sodium chloride solution in the electrolysis reaction. During the electrolysis process, hydrogen is also produced. Hydrogen is a flammable and explosive gas. ...
