Abstract

The invention relates to a smog chamber with vertical temperature gradient change. The smog chamber comprises a chamber body and a temperature grading control device, wherein the temperature grading control device comprises a compressor, a condenser, a drying filter and a multi-stage temperature control part which are sequentially connected by a pipeline to form a circulating system. The invention also provides a working method of the smog chamber. The smog chamber has the advantages that the different vertical atmosphere temperature changes can be simulated by the temperature grading control device, the simulation is closer to the real atmosphere condition, and the atmosphere vertical structure and the influence on atmosphere pollution is deeply understood; especially, the structure of a thermal inversion layer is simulated, and the influence on the atmosphere pollution by the thermal inversion layer is studied.

Description

technical field [0001] The invention belongs to the field of atmospheric environment test equipment, and relates to a smoke box with adjustable vertical temperature gradient and a working method thereof. Background technique [0002] The smog chamber is one of the experimental simulation tools for the laboratory to study the process of air pollution. The important chemical reaction process in the air pollution process can be extracted and simulated by using the smoke chamber, and the reaction conditions such as temperature, humidity, pollutant concentration, etc. can be artificially controlled to study the key influencing factors in the air pollution process, and the experiment is repeatable. In addition, the experimental results can be combined with the actual field monitoring to discover the law of air pollution and understand the nature of its pollution. [0003] The use of smoke chambers to simulate the process of air pollution began in Europe in the 1950s. In recent ye...
