Abstract

The invention provides a trapping and eliminating agent, a preparation method of the trapping and eliminating agent and a trapping and eliminating device. Through reasonable optimization of sodium thiosulfate, aluminum oxide and polyorganosiloxane, toxic gases such as hydrogen sulfide and chlorine gas are trapped and eliminated at the same time, and the prepared trapping and eliminating powder isbetter in stability and low in corrosivity; the fluidity during spraying is better, and the spraying rate reaches 98% or above; after spraying, the coverage area on leaked gas is large, and the mixingperformance is better; after trapping and eliminating operation, the trapping and eliminating agent is easy to clean and small in influence on the environment, and no aqueous solution needs to be added for auxiliary mixing in the preparation process, no high-temperature procedure or high-pressure procedure or heating or pressurizing is needed in the whole preparation process, no chemical reactionor combustion explosion possibility exists among the raw materials, the safety and the yield are high, and the cost is low; the technical problems that a powder product is severe in moisture absorption, insufficient in caking fluidity, low in powder spraying rate, low in diffusivity, severe in corrosion to equipment and the like are solved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a disinfectant and a preparation method thereof. Background technique [0002] my country is a big country in the production and use of hazardous acidic chemicals. The special properties of hazardous acidic chemicals determine that there are unsafe factors in the process of production, operation, storage, transportation, and use, and accidents are prone to occur, especially in acidic hazardous chemicals. In the process of monitoring and handling product leakage accidents, there is a lack of effective technical means and equipment. Hazardous acid chemicals mainly involve liquid chlorine, hydrogen sulfide, phosgene, hydrogen fluoride, sulfuric acid, nitric acid, hydrochloric acid and other acid hazardous chemicals. Leakage accidents often seriously endanger the production safety of the device and the life safety of personnel, and will seriously pollute the nearby air and damage the...
