Method for eliminating V-series chemical agents in closed environment

Abstract

The invention provides a method for eliminating V-series chemical agents in a closed environment, and relates to the field of sterilization. The problem that V-series chemical agents in closed environments such as the surface of instrument equipment, complex cavities and / or gaps are difficult to remove is solved. The method comprises the following steps: an atomization module is placed into or communicates with a closed disinfection space containing an instrument to be disinfected, wherein a first heating assembly is arranged in the atomization module, and a second heating assembly is arrangedat an outlet of the atomization module; a peroxide placed in a first reagent container is introduced into the atomization module, the first heating assembly atomizes and / or gasifies the peroxide, andthe peroxide stays in the disinfection space; a nitrogen-containing compound placed in a second reagent container is introduced into the disinfection space, and stays in the disinfection space; the two compounds are introduced repeatedly and stays in the disinfection space for a period of time, and disinfection is completed; and a residual reagent treatment module is started for purifying residual reagent. According to the method, V-series chemical agents in closed environments such as the surface of instrument equipment, complex cavities and / or gaps can be effectively eliminated, and high efficiency and environment friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of disinfection, in particular to a method for eliminating class V chemical agents in a closed environment. Background technique [0002] A Category V chemical agent is a neurotoxin that includes a substituted amine group and includes ethyl methylphosphonothioate with an internal amino group, such as o-ethyl-S-(2-diisopropylamine ethyl base) ethyl methylthiophosphonate (war agent VX), o-isobutyl-S-(2-diethyl)ethyl methylthiophosphonate, and o-S-diethylmethylthiophosphine ethyl acetate. Ethylthiophosphonate forms toxic hydrolysis products containing phosphonothiol acids. Typical such as VX is a transparent, amber, odorless, oily liquid, which can be mixed with water and dissolved in all solvents, and its volatility is very weak. [0003] Traditional technology usually uses water-based reagents to flush when eliminating V-type chemical agents. Although it can remove V-type chemical agents on the surface of ...
