Abstract

The invention provides a multi-channel online continuous VOC removal rate evaluation workstation; the workstation needs to be externally connected with a set of desktop computer or a mobile computer for controlling a volatile organic matter gas generating device, a gas-solid reaction unit module, a gas path control unit module and a double FID gas chromatograph; meanwhile, the computer needs to beinstalled with data collection, processing and real-time display software. The workstation is stable in temperature control, high in precision, stable in VOC gas concentration and flow, compact in structure and reliable in performance, and is an ideal device for high-efficiency, online and continuous detection of the VOC removal rate of the catalytic or adsorption materials by the research personnel of scientific research institutes, colleges and enterprises.

Description

technical field [0001] The invention relates to a multi-channel online continuous VOC removal rate evaluation workstation, which is used for efficient, online and continuous detection of the VOC removal rate of catalytic or adsorption materials by researchers in scientific research institutes, universities and enterprises. Background technique [0002] Outdoors, VOCs mainly come from industrial waste gas, vehicle exhaust, photochemical pollution, etc. from fuel combustion; indoors, they mainly come from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, construction and decoration materials, furniture, etc. , household appliances, automotive interior parts production, cleaning agents and human body emissions, etc. The impact of VOC on human health is mainly to stimulate eyes and respiratory tract, make skin allergies, cause headache, sore throat and fatigue, and it also contains many carcinogens. [0003] Due to the strong harmfulness...
