Problems solved by technology

[0003]The absorption method is adopted, the absorption efficiency of the absorption liquid is low due to the low concentration of pollutants, the subsequent processing of the absorption liquid is more troublesome, and it is easy to cause secondary pollution problems
[0004]The direct combustion method needs to heat the gas with a low concentration of pollutants to above the ignition point, which consumes a lot of energy and has high processing costs

Embodiment Construction

[0021] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] see figure 1 As shown, the above-mentioned method for treating waste gas in polluted soil is characterized in that: the method comprises the following steps:

[0023] (1) Tumbling: send the polluted soil into the operation workshop for tumbling. Generally, the workshop occupies a large area, and the workshop needs to be ventilated once an hour to bring out the dusty exhaust gas generated during the tumbling, and Transport the qualified soil out of the operation workshop;

[0024] (2) Dust removal: pass the dusty exhaust gas generated during the tumbling into the dust removal mechanism 1 for dust removal. In the method of this embodiment, the dust removal mechanism is a bag filter, and the dust is separated and collected through the filter material therein. It can purify dust-containing gas with a particle size greater than 0....

Abstract

The invention discloses a method used for processing waste gas in polluted soil. The method includes the steps that the polluted soil is sent into an operation workshop to be turned and aired; ventilation is conducted on the workshop so that the waste gas which is generated during turning and airing and carries dust can be brought out; dust removal is conducted on the waste gas; the gas where dust removal is conducted is discharged after being adsorbed and purified by activated carbon; the activated carbon is heated so that pollutants adsorbed and concentrated by the activated carbon can be steamed out; and the pollutants are introduced into a heating chamber to be heated and are then introduced into a catalysis combustion chamber to be combusted. The energy consumption is greatly lowered, and meanwhile secondary pollution can not be caused. Honeycomb ceramic is arranged in the catalysis combustion chamber for heat storage combustion, combusted gas exchanges heat with the pollutants which are steamed out, and therefore the waste gas processing cost is further reduced.

Description

technical field [0001] The invention relates to a method for treating waste gas in polluted soil. Background technique [0002] The existing methods for treating waste gas in polluted soil are generally absorption method and direct combustion method. [0003] With the absorption method, the absorption efficiency of the absorption liquid is low due to the low concentration of pollutants, the subsequent processing of the absorption liquid is more troublesome, and at the same time, it is easy to cause secondary pollution problems. [0004] The direct combustion method needs to heat the gas with a low concentration of pollutants to above the ignition point, which consumes a lot of energy and has high processing costs. Contents of the invention [0005] The purpose of the present invention is to provide a method for treating waste gas in polluted soil with low energy consumption and no secondary pollution. [0006] In order to achieve the above object, the technical scheme ad...
