Problems solved by technology

However, the single photocatalytic technology also faces the limitation of the reactor by the ultraviolet light source, low processing efficiency, low energy utilization rate, low photocatalytic performance, water vapor poisoning the catalytic performance of the catalyst, deactivation of the photocatalyst, and toxic by-products. It is difficult to deal with the disadvantages of high-concentration and large-volume gas

Abstract

The invention discloses a reactor for purifying organic waste gas under cooperation of plasmas and ultraviolet ray catalysis. The reactor comprises a shell and an insulation layer, wherein the insulation layer is fixed outside the shell; a plurality of plasma discharge units, a gas inlet, a gas outlet and a filter dust removal unit are arranged in the shell; each plasma discharge unit comprises two stainless steel plates which are located at two ends of the plasma discharge unit; each filter dust removal unit is located between each gas inlet and the corresponding plasma discharge unit; each gas inlet is connected with one end of each filter dust removal unit; and the other end of each filter dust removal unit is connected with the gas outlet through the multiple plasma discharge units. According to the reactor for catalytically purifying the organic waste gas under cooperation of the plasmas and the ultraviolet ray catalysis, the plasmas, photocatalysis and adsorption action are organically combined, so that thorough decomposition and harmlessness of the organic waste gas are realized; the plasmas and the photocatalysis promote each other and work synergistically, so that the effect is outstanding.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment devices, in particular to a reactor for catalytically purifying organic waste gas with plasma and ultraviolet light. Background technique [0002] Organic waste gas, especially volatile organic compounds (VOCs), is one of the important sources of air pollution and a substance that is extremely harmful to human health. Most VOCs are toxic, carcinogenic and have a special odor, which will affect the skin and mucous membranes and cause acute damage to the human body. Even many VOCs have been identified as carcinogens, such as formaldehyde, polycyclic aromatic hydrocarbons, and aromatic amines. Most VOCs can also react with hydrocarbons and NOx in the atmosphere to form photochemical smog, causing secondary pollution. Part of the VOCs of halogenated hydrocarbons, entering the upper air layer will also cause the destruction of the ozone layer. Research and development of highly efficient ...
