Simulated poison cloud generation system

Abstract

The invention discloses a system for simulating toxic agent cloud generation, which comprises a gaseous or liquid volatile gas standard gas generating device, a gas distribution device, a heating gas absorption pool and a high and low temperature black body radiation source; a gaseous or liquid volatile gas standard gas generating device The generated standard gas enters the gas distribution device through the gas pipe, and the gas distribution device prepares a certain concentration of gas and introduces it into the heating gas absorption cell through the gas pipe; the high and low temperature blackbody radiation source, the light entrance and exit holes of the gas absorption cell and the FTIR spectrometer are located on the same optical path; When the simulated poison cloud is analyzed, the infrared radiation light is emitted by the high and low temperature blackbody radiation source, enters the sample pool through the light entrance hole of the gas absorption cell, passes through the simulated poison cloud in the gas absorption cell, and then exits through the light exit hole of the gas absorption cell , into the FTIR spectrometer, and finally the computer controls the FTIR spectrometer to collect, analyze and store infrared spectral radiation data. The invention can precisely control the temperature and concentration, and can generate simulated poison clouds with different temperatures and concentrations, which can meet the needs of research and reduce the potential harm to workers.

Description

technical field [0001] The invention relates to the field of environmental detection technology and analysis and optics, in particular to a system for simulating poison cloud generation. Background technique [0002] In today's society, the binary or multi-component compound pollution of gaseous or liquid inorganic substances and organic substances is on the rise. Diverse pollution under concentration conditions. To study these diversified and diverse pollution situations, it is particularly important to prepare simulated poison vapors at different temperatures and concentrations. [0003] At present, simulated poisons are mainly prepared simply in the laboratory, which cannot accurately control the temperature and concentration, and the laboratory gas volume is small, which cannot meet the needs of research, and simulated poisons have certain potential hazards to laboratory workers. The invention introduces a simulated poison cloud generation system, which can generate si...
