Description
Technical Field

Background
Among all environmental pollution factors, air pollution has the characteristics of fast diffusion, wide influence range and great treatment difficulty, and especially odor emitted around garbage transfer, kitchen waste treatment plants and the like has technical limitations of low detection threshold, great odor and the like in the analysis, detection and treatment processes. Some of the malodorous components in very low levels can result in severe malodorous odors, posing significant technical challenges to the analytical detection and targeted processing of the malodorous components.
For the treatment of malodorous gas, the key point is the accurate determination of components, and the determination of trace components in the malodorous gas needs to improve the concentration of the components to be detected by a corresponding enrichment technology. Most of the enrichment methods in the prior art are adsorption enrichment, but most of the odoriferous trace components are discharged in an unorganized manner, so that the problems of long enrichment time, difficulty in determining concentration times and the like exist in the enrichment process, the enrichment efficiency is low, the time is long, and the enrichment and analysis treatment of the trace components are not facilitated.
In addition, in malodorous gases in which trace components are present, a large amount of water vapor is often contained together. After the water vapor enters the adsorbing material, the water vapor occupies the adsorption sites of the trace components in the odor, so that the adsorption capacity of the adsorbing material on the trace components is reduced, and the enrichment of the trace components is also influenced. Since the concentration of the trace component is too low, it is necessary to keep the adsorption unit in a temperature environment as low as possible in order to improve its adsorption efficiency. However, the low temperature environment also causes liquefaction or desublimation of water vapor in the odor to be treated, and easily causes structural damage of the adsorbent. Therefore, how to solve the interference of water vapor in odor to the enriched gas is a problem which needs to be rescued urgently.
