Liquid-chlorine production system

Abstract

The invention discloses a liquid-chlorine production system. A chlorine-gas generating device is connected with a chlorine compressor I which is connected with a cooling device I; the cooling device I is connected with a liquefier and a finished-chlorine-gas collecting device; the liquefier is connected with a freezing device I and a gas-liquid separator; a liquid-chlorine groove I and a liquid-chlorine groove II are arranged between the liquid-chlorine collecting device and the gas-liquid separator; an extraction pump I is arranged between the liquid-chlorine groove I and the liquid-chlorine groove II and connected with the liquid-chlorine groove I and the liquid-chlorine groove II; the liquid-chlorine groove II is connected with an extraction pump II; the gas-liquid separator is connected with the liquid-chlorine collecting device and a buffer which is connected with a separator; the separator is connected with an absorbing tower; an absorbing tower II is connected with the chlorine compressor I and the separator. The liquid-chlorine production system disclosed by the invention has the advantages that improvement is carried out by production-equipment connection relation, and collection and storage are carried out according to the state of chlorine gas, so that the production efficiency of the liquid chlorine is improved, multiple utilization of the chlorine gas is realized, and the air pollution caused by incomplete collection is avoided.

Description

technical field [0001] The invention relates to a system, in particular to a liquid chlorine production system. Background technique [0002] Chlorine, the chemical formula is Cl?. It is yellow-green under normal temperature and pressure, and has a strong pungent odor. oxidizing agent. When chlorine gas is mixed with hydrogen gas with a volume fraction above 5%, there may be a danger of explosion when exposed to strong light. Chlorine can undergo substitution and addition reactions with organic and inorganic substances to generate various chlorides. Chlorine was used as a bleaching agent in the paper and textile industries in the early days. Chlorine in a free state in nature exists in the atmosphere and is one of the main elements that destroy the ozone layer. Chlorine gas is decomposed by ultraviolet rays into two chlorine atoms (free radicals). Most usually exist in the form of chloride, the most common being sodium chloride. The melting and boiling point of chlori...
