Abstract

The invention discloses a method for treating an organic waste gas through low-temperature plasma concerted catalysis. The treating steps are as follows: (1) pre-treating the organic waste gas to be treated, using manners of water cooling and filtering to perform cooling, dust removal and dehumidification on the organic waste gas; (2) sending the pre-treated organic waste gas into a low-temperature plasma concerted catalysis area, decomposing the organic waste gas by using low-temperature plasma concerted catalysis, and generating harmless micro-molecules; (3) sending the gas treated in the low-temperature plasma concerted catalysis area into an adsorption reaction area, and adsorbing organic molecules and high energy molecules which are not completely reacted by using an adsorbent, so as to further oxidize and decompose the organic molecules; (4) discharging the pollution-free gas after decomposing and oxidization through a discharge tower. The method has high purification efficiency on the organic waste gas, is good in effect, is less affected by various environments and external conditions, and especially has high purification efficiency on the organic waste gas with high flow, low concentration, and complex composition.

Description

technical field [0001] The invention relates to the fields of environmental engineering and plasma science and technology, and more specifically relates to a method for low-temperature plasma synergistic catalytic treatment of organic waste gas. Background technique [0002] With the continuous development of social economy and the continuous acceleration of industrialization, environmental and energy issues have been paid more and more attention by people. Large-scale industrial production and the discharge of people's daily life will produce a large amount of organic waste gas of varying degrees, which poses a serious threat to the living environment of human beings. At present, most industrial organic waste gases have the characteristics of low concentration, large air volume, and multiple components, and the traditional treatment process can no longer meet the treatment requirements. [0003] Traditional treatment methods include absorption, adsorption, condensation and...
