Chlorine water treatment in vacuum dechlorination process

Chlorine water is recovered and treated, chlorine and condensed water are separated and added to different processes, respectively, so that the active components of chlorine water are returned to the chlor-alkali production system. This not only solves the problem of polluting the environment due to the discharge of chlorine water, but also saves The use of caustic soda reduces the production cost and achieves the purpose of reducing consumption and increasing efficiency. In the entire process production, there is no emission of waste gas and waste water, and it belongs to the clean production process. Currently, the Chinghua Group adopts this chlorine water treatment method. It uses a vacuum dechlorination device to recycle chlorine water. The separated wet chlorine gas is sent to the chlorine treatment process for drying, and the dechlorination condensate water is sent to the brine salt. Gang. Since the pump is used to add the chlorine water to the vacuum dechlorination process in an intermittent manner, the chlorine water in the storage tank is periodically pumped after reaching a certain liquid level.

Our company's chlorine water treatment is located in the vacuum dechlorination process. Chlorine water from the chlorine scrubber tower first enters the chlorine water storage tank. When the chlorine water level reaches a certain height, the pump decomposes into a vacuum dechlorination process. Dechlorination vacuum pump liquid ring sealant, the rest of the chlorine water pump into the salt water pipeline and light salt water together into the dechlorination tower, so as to achieve the purpose of chlorine dechlorination. The separated wet chlorine gas enters the chlorine treatment process together with the wet chlorine gas from the electrolytic cell to be dried. The condensed water in the chlorine gas together with the dilute salt water removes the free chlorine and then removes the salt. The use of vacuum dechlorination equipment to recover chlorine water, to avoid the environmental pollution caused by the discharge of chlorine water, recover the active ingredients in chlorine water, and create considerable economic and social benefits. The vacuum dechlorination production process is an environmentally friendly production process and is recommended for use in chlor-alkali enterprises.
