Abstract

The invention relates to a waste gas treatment device, and belongs to the technical field of environmental protection. A photochemistry coupling low-temperature plasma waste gas treatment device comprises a shell, wherein the bottom of the shell is provided with a water exhaust opening; the left side wall and the right side wall of the shell are respectively provided with a gas inlet and a gas outlet; a communicated air duct is formed between the gas inlet and the gas outlet; the air duct is internally provided with a rough filtering module, an ultramicro purifying module, a baffle plate demister and a photochemistry coupling low-temperature plasma module sequentially at the direction from the gas inlet to the gas outlet; the device is also provided with a PLC (programmable logic controller) system and a circulation water filtering system. The photochemistry coupling low-temperature plasma module provided by the invention combines ultraviolet rays and a low-temperature plasma electromagnetic field organically and integrally; ultraviolet irradiation can promote the reaction effect and velocity of low-temperature plasma, and improve the treatment efficiency; the device is provided with the PLC system which is simple to operate; the circulation water filtering system of the device can save water resource effectively.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a photochemically coupled low-temperature plasma waste gas treatment device. Background technique [0002] In modern industrial production, some toxic and harmful waste gas will inevitably be produced along with the production process. This waste gas is directly discharged into the atmosphere, polluting the air quality and causing serious harm to human health. Relevant national laws and regulations and industry standards have strict restrictions on gas emission standards, and the control of polluted gases is the key to improving environmental quality. [0003] Traditional waste gas pollution control technologies include adsorption, condensation, biological and combustion methods. The adsorption method mainly uses activated carbon for adsorption, and the purification effect is ideal, but the activated carbon needs to be regenerated after the adsorption is saturated, and the regener...
