Integral type organic waste gas treatment device

Abstract

The invention discloses an integral type organic waste gas treatment device which comprises a shell, wherein an air inlet is formed in a side surface of the shell; an air outlet is formed in the upperend surface or the lower end surface of the shell; a rotating main shaft extending outside from inside is arranged inside the shell; a speed reduction motor is arranged at an end part, outside the shell, of the rotating main shaft; a first filtering cylinder, a second filtering cylinder and a third filtering cylinder are sequentially arranged inside the shell in a layer to layer manner; a plurality plasma bodies and ultraviolet lamp tubes which are distributed at annular intervals are arranged between the first filtering cylinder and the second filtering cylinder; an activated carbon layer isarranged between the second filtering cylinder and the third filtering cylinder; the upper end and the lower end of the first filtering cylinder are respectively connected with the interior of the shell; an upper sealing end cover and a lower sealing end cover are respectively arranged at two ends of the second filtering cylinder and the third filtering cylinder; the rotating main shaft penetrates through the shell, the upper end cover and the lower end cover. The integral type organic waste gas treatment device has the effects of being high in waste gas treatment efficiency, thorough in waste gas treatment, low in energy consumption and long in service life.

Description

technical field [0001] The invention belongs to the field of air purification equipment, in particular to an integrated organic waste gas treatment device. Background technique [0002] In the past 20 years, with the rapid development of modern industry, the annual discharge of toxic and harmful waste gas into the environment has increased significantly. The resulting amount of volatile organic compounds (VOCs) has also risen sharply, and VOCs have become one of the main gaseous pollutants plaguing countries around the world. A large amount of VOCs emissions have caused extremely serious harm to human health and the living environment. If VOCs remain in the air for a short or long period of time, exposure to VOCs can cause cancer, eye inflammation, and breathing difficulties. In addition, VOCs are mainly active in the atmospheric reaction of stratospheric ozone and environmental problems. Under the conditions of low pollutant concentration and large total amount in the env...

Problems solved by technology

Problems existing in the current conventional patented technology: ① In the plasma electric field part, due to the large amount of gas processing, in order to ensure the necessary residence time, it is often necessary to have a long processing channel. Generally, multiple groups are designed in series and the electrode length is increased. In the future, the power consumption and cost of the equipment will rise sharply, and the discharge will be unstable.

②In order to control operating costs, reduce equipment investment, reduce power input, and reduce the length of effective treatment channels, the residence time of gas inside the equipment cannot be guaranteed, and the treatment effect cannot meet expectations

③In the ultraviolet photolysis part, due to the large gas volume, in order to reduce the loss of airflow resistance, the filter screen area is set larger, the number of corresponding lamp tubes is larger, the distance between the lamp tubes and the distance between the lamp tubes and the catalyst is relatively large, and the light intensity of the catalyst is low , the processing effect is poor

④ The catalyst carrier generally adopts a thin filter screen made of honeycomb matrix structure or activated carbon fiber, which has limited interception capacity for organic waste gas

⑤The filter screen adopts a plug-in flat plate structure, and there is a phenomenon of airflow short circuit around it, which affects the treatment effect

⑥ When there are many gas impurities, the filter screen at the front end is seriously blocked

⑦ Low-temperature plasma has the problem of ozone pollution
