Sodium hypochlorite generator

Abstract

The invention relates to the technical field of electrolysis equipment, in particular to a sodium hypochlorite generator. The sodium hypochlorite generator comprises an electrolytic bath assembly, a saline water tank and a clear water tank, wherein the electrolytic bath assembly comprises electrolytic bath bodies, heat exchange elements and an electrode assembly; a saline water inlet pipe of the saline water tank, a plurality of electrode assemblies and a sodium hypochlorite outlet pipe form a series connection structure; and the clear water tank is connected in series with the heat exchange elements in a plurality of the electrolytic bath bodies through a cooling water inlet pipe, and cooling water in the heat exchange elements flows into the saline water tank through a cooling water outlet pipe. According to the invention, electrolyte inlet temperature is monitored, and when the inlet temperature is low, cooling water quantitatively extracts saline water from the saline water tank, and heat exchange is carried out through the heat exchange elements and an electrolyte, so the inner water temperature of the saline water tank is increased, and then the inlet temperature is increased. The temperature of an electrolyte outlet can be effectively reduced through baffling devices on the heat exchange elements, and the temperature of the electrolyte can be effectively controlled by monitoring the temperature of the electrolyte and performing feedback regulation on the flow of cooling water.

Description

technical field [0001] The invention relates to the technical field of electrolysis equipment, in particular to a sodium hypochlorite generator. Background technique [0002] Sodium hypochlorite solution is a truly efficient, broad-spectrum and safe strong sterilizing and anti-virus agent. It has good affinity with water and can be miscible with water in any proportion. There is no safety hazard of liquid chlorine, chlorine dioxide and other agents. , and its disinfection effect is recognized as equivalent to chlorine. Because sodium hypochlorite is easy to decompose and difficult to store and transport, the on-site disinfection (disinfection and microbicide) is often prepared on-site by sodium hypochlorite generators. The salt water type sodium hypochlorite generator uses salt water with a concentration of 3wt% to 5wt% and electricity as raw materials to prepare a certain concentration of sodium hypochlorite solution on site. Existing brine type sodium hypochlorite genera...
