Volume-adjustable smog chamber

Abstract

The invention provides a volume-adjustable smog chamber, capable of being used for atmospheric environment simulation tests. The volume-adjustable smog chamber comprises a first support, a second support and a third support arranged between the first support and the second support, wherein the third support is fixedly connected with the second support by multiple supporting rods, and the third support is fixedly connected with the first support by multiple slide rails; a sliding support capable of moving along the slide rails is supported among the slide rails, and a Teflon gas bag is arranged between the sliding support and the second support. According to the volume-adjustable smog chamber, by arranging the sliding support, the sliding support can be moved along the slide rails, so as to obtain any required test volume between minimum design volume and maximum design volume of the Teflon gas bag, and any test volume requirement can be met; the design of the volume-adjustable smog chamber can meet the volume requirements of different tests.

Description

technical field [0001] The invention relates to the field of atmospheric environment test equipment, in particular to a volume-adjustable smoke box which can be used for simulating atmospheric environment experiments. Background technique [0002] The smoke chamber is one of the tools for atmospheric environment simulation experiments. It can simulate the chemical process in the atmosphere, so that the essence of the chemical reaction in the atmospheric environment can be extracted from complex experimental phenomena, and the experimental conditions can be controlled and changed artificially, and repeated experimental research can be carried out. Rational research has great advantages in solving environmental pollution problems under complex conditions. Combining the smog chamber that simulates the atmospheric environment with the study of chemical reaction models, and comparing it with field measurements, we can gain an in-depth understanding of the mechanism of photochemi...

AI Technical Summary

Problems solved by technology

However, the existing smog boxes all have the defects of inaccurate simulated atmospheric environment in the smog box, long ventilation and cleaning time and low efficiency. Clean air for cleaning, the process of air exchange and cleaning is very long and the efficiency is very low

On the other hand, when the photochemical simulation reaction test is carried out in the smog box, part of the gas will inevitably be consumed or released, resulting in changes in the gas pressure and concentration in the smog box, and the constant pressure reaction cannot be achieved in the smog box. If the pressure of the gas is kept constant, the gas concentration in the smoke box will change, resulting in inaccurate results of the simulation test.
