Abstract

The invention provides a heat treatment workshop waste gas plasma purification device and purification method, and belongs to the technical field of waste gas treatment. The problems that existing heat treatment workshop waste gas treatment is not high in effect and poor in waste gas selectivity, and technological conditions do not conform to industrial characteristics are solved. The device comprises a mechanical dust removal module, a waste gas washing module, a plasma primary purification module and a plasma secondary purification module which are transversely and sequentially arranged in series; the mechanical dust removal module is used for carrying out mechanical dust removal and separation on granular smoke dust and dust in the waste gas; the waste gas washing module is used for purifying and separating water-soluble pollutants in waste gas, the plasma primary purification module comprises a first gas distribution plate, a dielectric barrier discharge assembly and a photolysis catalytic plate, and the plasma secondary purification module comprises a second gas distribution plate, a needle net discharge assembly and an activated carbon fiber filter net. The device is mainly used for purifying waste gas in heat treatment workshops.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a waste gas plasma purification device and a purification method in a heat treatment workshop. Background technique [0002] Basic materials and their properties have always restricted China's economic and social development. The heat treatment of metal materials is an important part of it. The waste gas generated during the heat treatment process has become increasingly prominent in environmental pollution. Due to the different equipment and processes of heat treatment, the exhaust gas pollutants are also different, including various types of smoke, dust, oil fume, hydrocarbons and other harmful gases. As the fourth state of matter, plasma technology has been widely used in material surface treatment, gas purification and other fields. At present, the country advocates green manufacturing, and calls for the transformation and upgrading of the heat treatm...
