Problems solved by technology
However, the emission of harmful gases will not remain constant. In order to ensure that it can be completely processed, the combustion volume of the equipment must be made very large, which not only takes up a large equipment space, but also wastes part of the processing capacity of the combustion equipment. , which increases the processing cost of harmful gases; in addition, it is difficult to achieve complete purification of harmful gases after catalytic combustion, and if discharged into the air, it will still cause slight pollution to the environment

The invention discloses an adsorption catalysis device for harmful gas. The adsorption catalysis device comprises a storage apparatus and a reactor, wherein the storage apparatus is used for storing the harmful gas, and the reactor is used for performing adsorption catalysis operation on the harmful gas; a gas purification unit is fixedly arranged in the reactor; and the gas purification unit comprises an adsorption part, a low temperature combustion part and a photocatalysis part, wherein the adsorption part is used for performing selective treatment on the harmful gas, the low temperature combustion part is used for making the harmful gas to burn, and the photocatalysis part is used for performing photocatalysis treatment on the harmful gas. According to the adsorption catalysis device disclosed by the invention, selective adsorption and desorption can be performed on the harmful gas according to the concentration of the harmful gas, so that the harmful gas can be purified by a relatively stable emission load; thus, not only is the size of purification equipment reduced but also the gas purification unit can be fully utilized, and therefore, the treatment cost of the harmful gasis reduced; and the photocatalysis part arranged at the downstream position of the low temperature combustion part is capable of further performing photocatalytic degradation on gas led out from the low temperature combustion part to guarantee the out-emission purity of the harmful gas in an intensified manner.
Description
technical field [0001] The invention relates to the technical field of industrial waste gas treatment, in particular to an adsorption and catalytic device for harmful gases. Background technique [0002] Organic waste gas is a common pollutant discharged from petrochemical, light industry, plastic, printing, coating and other industries. Organic waste gas often contains hydrocarbon compounds (aromatics, alkanes, olefins), oxygen-containing organic compounds (alcohols, ketones, organic acids, etc.) , Nitrogen, sulfur, halogen and phosphorus-containing organic compounds, etc. If these harmful gases are directly discharged into the air, atmospheric environmental problems such as greenhouse effect, ozone layer depletion and acid rain will become more serious, causing continuous harm to humans, animals and plants. In the prior art, there are many ways to treat the above-mentioned harmful gases. The catalytic combustion method has the characteristics of truly eliminating exhaust ...
