Abstract

The present invention discloses one kind of chlorine collecting agent and its preparation process. The chlorine collecting agent is prepared with calcium hydroxide, surfactant, filming drier, diluent and sodium silicate. It has high chlorine eliminating efficiency, waterproof and moistureproof property, no caking, high air permeability and other advantages. It is used in absorbing and eliminating chlorine in various kinds of production fields, such as chloralkali plant, papermaking mill, textile mill, sewage treating yard, etc.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a chlorine gas scavenger and its preparation method and application. Background technique [0002] Chlorine gas is widely used in various production fields, such as chlor-alkali plants, paper mills, textile mills, sewage treatment plants, water plants, and pharmaceutical plants. Usually, chlorine gas is stored and used in steel cylinders, and some manufacturers transport or use chlorine gas through pipelines. Since chlorine gas is a liquid after high-pressure treatment in the storage state and a gas in the normal state, it is difficult to seal and easy to leak during storage and use. Because of insufficient sealing means and improper operation methods, chlorine gas will leak. Chlorine gas is highly toxic and harmful to the human body and the environment. Therefore, when chlorine gas leaks, the leaked chlorine gas must be treated so that it cannot spread to the surroundin...
