Laboratory waste gas treatment system and treatment method thereof

Abstract

The invention discloses a laboratory waste gas treatment system and a treatment method thereof. The key point of the technical scheme is as follows: the laboratory waste gas treatment system comprisesa gas inlet unit, a mixing unit, an adsorption unit, an inorganic treatment unit, an organic treatment unit and a power unit which are arranged sequentially; the units are communicated through pipelines; the inorganic treatment unit comprises a plurality of first solution boxes which are connected in parallel; liquid for adsorbing inorganic matters in the waste gas is accommodated in the first solution boxes; a second control valve for controlling a gas path to open and close is arranged at the gas inlet end of each first solution box; the organic treatment unit comprises a plurality of second solution boxes which are connected in parallel; liquid for adsorbing organic matters in the waste gas is accommodated in the second solution boxes; and a third control valve for controlling a gas path to open and close is arranged at the gas inlet end of each second solution box, so that the effect of effectively treating the inorganic matters and the volatile organic compounds (VOC) in the laboratory waste gas is achieved.

Description

technical field [0001] The invention relates to the field of air purification, more specifically, it relates to a laboratory waste gas treatment system and a treatment method thereof. Background technique [0002] Laboratory waste gas is extremely harmful to the human body and must be treated and made harmless before it can be discharged. The Chinese patent with the existing publication number CN107890774A discloses a laboratory exhaust gas treatment method, comprising the following steps: a) controlling the content of solid particles in the exhaust gas: measuring the instant content of solid particles in the exhaust gas, if the instant content of solid particles is higher than If the preset threshold value is used, the instant content of solid particles in the laboratory exhaust gas will be reduced until the instant content of solid particles is lower than the preset threshold value; b) the exhaust gas that meets the solid particle content will be combined with the waste ga...

Problems solved by technology

However, the above-mentioned scheme only provides a solution for the laboratory exhaust gas with relatively high particulate matter content, but the actual laboratory exhaust gas not only includes particulate matter, but also contains a large amount of inorganic and organic substances in more cases. The scheme in the above-mentioned patent Unable to cope with this laboratory exhaust, the problem needs to be solved
