Embodiment Construction

[0021] figure 1 is a schematic structural diagram of an exhaust gas purification device according to an embodiment of the present invention. Such as figure 1 As shown, the exhaust gas purification device of the present invention includes a particle charging unit 1 , an electrocoagulation unit 2 and an electrostatic precipitator unit 3 . The particle charging unit 1 is used to charge the particles when they flow through the high-voltage corona electric field between the electrodes; Particles are charged particles through the inertial collision between particles, particle diffusion, space charge force, heteropolar attraction between particles, image force between particles or between particles and the wall to make the fine particles condense; the electrostatic precipitator unit 3 is set in the electric Downstream of the coalescing unit 2, large particles are adsorbed to the electrodes by ionizing the gas using an electrostatic field. The indoor exhaust gas purification device...

Abstract

The invention provides a waste gas purifying device and relates to the field of waste gas purification. The waste gas purifying device comprises a particle electric charge unit, an electric coagulation unit and an electrostatic precipitation unit. The particle electric charge unit is used for making particles be charged when the particles flow through a high-voltage corona field; the electric coagulation unit is arranged at the downstream side of the particle electric charge unit and is used for coagulating small particulate matters into large particulate matters; the large particulate mattersmake fine particles be coagulated by virtue of the charged particles due to inertia collision between particles, particle diffusion, space charge force, heteropolar attraction between the particles and image force between the particles or between the particles and a wall surface; and the electrostatic precipitation unit is arranged at the downstream side of the electric coagulation unit and is used for realizing gas ionization by using an static electric field so as to adsorb the large particles to an electrode. The indoor waste gas purifying device provided by the invention improves the treatment effect on indoor waste gas by adopting the electric coagulation unit.

Description

technical field [0001] The invention relates to the field of exhaust gas purification, in particular to an exhaust gas purification device. Background technique [0002] Common indoor exhaust gas pollutants can be classified as follows: inhalable particulate matter, represented by fine particulate matter PM2.5 (ParticulateMatter2.5); biological pollutants, represented by other microbial aerosols such as bacteria, viruses and fungi; VOCs ( Volatile Organic Compounds), whose representatives are formaldehyde, benzene series and other gaseous pollutants released from home decoration and household chemicals [1]. In addition, indoor cooking and smoking can emit various compound pollutants. Indoor volatile organic compounds (VOCs) are mainly produced in wood-based panels, various paints, coatings, adhesives, furniture, and combustion products. There are more than 500 types of volatile organic compounds in indoor exhaust gas, and more than 20 types have carcinogenic effects; indoor...
