Problems solved by technology

It turned out that all of them were discharged into the ditch as one of the three wastes, which not only caused the pollution of the factory area and the surrounding environment by chlorine water, but also caused a waste of chlorine and caused undue losses
At the same time, the sodium hypochlorite needed in chemical production is generally produced by raw chlorine, which has high production costs and low resource recycling rate.

Abstract

The invention discloses a device for producing sodium hypochlorite by using waste chlorine water and a production method thereof. The device comprises a chlor-alkali producing device, a waste chlorine collecting device and a reaction device, and a waste chlorine collecting pipeline is arranged between the chlor-alkali producing device and the waste chlorine collecting device. The production method comprises that: firstly, all chlorine water generated by the chlor-alkali producing device in the normal producing process enters the waste chlorine collecting device through the waste chlorine collecting pipeline; and then the chlorine water is added with alkali liquor through the reaction device for reaction to generate the sodium hypochlorite. The production method solves the problem of pollution by draining the chlorine water, realizes zero emission of the waste chlorine water, and improves the environmental protection and social benefits.

Description

technical field [0001] The invention relates to a device for producing sodium hypochlorite by using waste chlorine water and a production method thereof, belonging to the technical field of chemical industry. Background technique [0002] Chlorine water is the waste water inevitably produced in the production of chlor-alkali chemical industry. It is mainly composed of accumulated water in the chlorine gas transmission pipeline, condensed water of the chlorine gas two-stage titanium cooler, and condensed water of the chlorine gas scrubber. The available chlorine content is about 7.5%, and the temperature is about 60 ° C. . It turned out that all of them were discharged into the sewer as one of the three wastes, which not only caused the pollution of the factory area and the surrounding environment by chlorine water, but also caused the waste of chlorine and caused unnecessary losses. At the same time, the sodium hypochlorite needed in chemical production is generally produce...
