Injection type low-temperature plasma device for treatment of organic waste gas

Abstract

The invention provides an injection type low-temperature plasma device for treatment of organic waste gas. The device comprises a filter cylinder, a low-temperature plasma generator and a mixing cylinder, wherein a gas inlet cylinder is arranged in the filter cylinder, a plurality of gas outlets are formed in the cylinder wall of the air inlet cylinder, and the outer wall of the air inlet cylinderis wrapped with a first filter element covering the multiple gas outlets; a gas inlet of the low-temperature plasma generator is communicated with the interior of the filter cylinder through a firstgas guide pipe, and a gas outlet of the low-temperature plasma generator is communicated with the interior of the mixing cylinder through a second gas guide pipe; an inner barrel and an outer barrel which are coaxially arranged with the mixing cylinder are sequentially arranged outside the mixing cylinder, a second filter element is arranged between the inner barrel and the outer barrel, a secondgas inlet pipe communicated with a filter cavity is connected to the outer barrel, and a plurality of third gas guide pipes are arranged on the inner wall of the inner barrel; and a plurality of fourth gas guide pipes penetrating through the mixing cylinder are arranged on the mixing cylinder. After low-temperature plasma treatment is carried out on waste gas, biological treatment is continuouslycarried out on the waste gas; and since multiple treatment is carried out, safety and environment friendliness of exhausted gas are effectively guaranteed.

Description

Technical field[0001]The invention relates to the technical field of organic waste gas treatment, in particular to an injection type low-temperature plasma treatment device for organic waste gas.Background technique[0002]At present, the commonly used treatment devices for odor and odor waste gas have problems such as high operating costs, high equipment and operation management requirements, large floor space, low purification efficiency, easy secondary pollution, and susceptibility to pollutant concentration and temperature. Low-temperature plasma degradation of pollutants uses the action of high-energy electrons, free radicals and other active particles and pollutants in the exhaust gas to decompose pollutant molecules in a very short time to achieve the purpose of degrading pollutants. However, the existing exhaust gas treatment equipment is limited by its structure, and there are still shortcomings in the treatment effect, and it is urgent to improve.Summary of the invention[000...
