Novel chlorine pipeline dewatering device

Technical Field

The utility model relates to a chemical industry equipment technical field, concretely relates to chlorine pipeline water trap.

Background

Chlorine is a highly toxic gas which is yellow green at normal temperature and normal pressure, has strong pungent smell, has suffocating property, has density larger than that of air, is soluble in water and alkali solution, is one of main products in the chlor-alkali industry, and can be used as a strong oxidant. Chlorine gas is toxic, invades into the human body mainly through respiratory tract and dissolves in water contained in mucous membrane, and can cause damage to the mucous membrane of the upper respiratory tract, cause dyspnea and severe cough, and when the symptoms are serious, pulmonary edema can occur, so that the circulation is difficult to cause death. Chlorine gas entering the body from the esophagus can cause nausea, vomiting, chest pain and diarrhea.

The chlorine can be in illumination reaction with toluene to obtain the commonly used chemical and medical intermediate benzyl chloride. However, since chlorine gas produced in the chlor-alkali industry contains moisture, hydrochloric acid and hypochlorous acid obtained by the reaction of chlorine gas with water corrode pipelines, and the aqueous chlorine gas enters into chlorination reaction, side reactions are also caused. Therefore, in the process of producing benzyl chloride, in order to ensure normal production and prevent corrosion of equipment pipelines, the moisture in the chlorine pipeline must be controlled and eliminated.
