Movable smog chamber

Abstract

The invention provides a movable smoke box, at least including: a foldable circular chassis, an umbrella-shaped support, and a protective film laid on the chassis and the umbrella-shaped support, and a collection hole is opened on the protective film , the umbrella-shaped bracket is fixed to the chassis through a plurality of fixing clips. The movable smog box of the present invention is easy to assemble when in use, and easy to disassemble when put away, and is suitable for deploying mechanism observations on waste gas from pollution sources, photochemical reactions of semi-volatile organic compounds, secondary generation of organic aerosols, etc. in smaller occasions. Compared with the current large and super-large smoke boxes, the movable smoke box of the present invention occupies a small area, is easy to move, is convenient to replace, and greatly reduces the cost of production, use, cleaning and maintenance. It can be built in the laboratory, automatically Stations, super stations, mobile vehicles, platforms near pollution sources, etc. any flat place. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial application value.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a movable smoke box. Background technique [0002] Primary pollutants such as hydrocarbons and nitrogen oxides discharged into the atmosphere by pollution sources such as automobiles and factories undergo chemical reactions under the action of sunlight to generate secondary pollutants such as ozone, aldehydes, ketones, acids, and peroxyacetyl nitrate The smog pollution phenomenon formed by the mixture of primary pollutants and secondary pollutants participating in the photochemical reaction process is called photochemical smog. [0003] In order to understand the mechanism of photochemical reactions, scientific research institutions at home and abroad have generally carried out experimental studies using photochemical smog chambers to simulate atmospheric photochemical reactions. The use of smoke chambers to carry out atmospheric environmental chemical simulation research...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a movable smoke box, which is used to solve the problems in the prior art that the smoke box is large in size, unsuitable for small sites, difficult to move, and high in maintenance costs.
