Description

TECHNICAL FIELD

[0001] The utility model relates to industrial waste gas treatment field especially, and it is a kind of industrial waste gas treatment device based on plasma technology. BACKGROUND

[0002] The method for industrial waste gas treatment includes activated carbon adsorption, catalytic combustion, catalytic oxidation, acid-base neutralization and plasma method, among which, low-temperature plasma is the fourth state of matter after solid, liquid and gas. When the applied voltage reaches the discharge voltage of gas, the gas is broken down, producing a mixture including electrons, various ions, atoms and free radicals. Although the electron temperature is very high during discharge, the temperature of heavy particles is very low, and the whole system presents a low-temperature state, so it is called low-temperature plasma. Low-temperature plasma degrades pollutants by using these active particles such as high-energy electrons and free radicals to act on pollutants in waste gas, so that the pollutant molecules are decomposed in a very short time and undergo subsequent reactions to achieve the purpose of degrading pollutants.

[0003] At present, the existing waste gas treatment device on the market has a complex structure. For example, a double dielectric barrier low-temperature plasma industrial waste gas treatment device with publication number CN209952556U. First, start the exhaust motor, and the output shaft of the exhaust motor drives the exhaust fan blades. At this time, the waste gas enters from the air inlet pipe. When passing through the drying box and water absorption net plate, the moisture in the waste gas is absorbed. At this time, the waste gas enters the pretreatment chamber. When passing through the waste gas filtering device, the filter screen filters out the dust in the waste gas. The air passes through the HEPA filter plate, and the particles in the waste gas are adsorbed. The activated carbon plate adsorbs the toxic substances in the waste gas. At this time, the anode is immediately powered. When the gas enters the double dielectric barrier discharge chamber, under the action of high-energy electrons, the odor molecules are excited, and the chemical bonds between charged particles or molecules are broken. At the same time, oxygen in the air will also produce strong oxidizing substances under the bombardment of high-energy electrons. These strong oxidizing substances will also react with odor molecules to decompose them, thereby promoting the elimination of odor. The purified gas is discharged through the exhaust pipe. However, when the double dielectric barrier low-temperature plasma industrial waste gas treatment device filters out the dust in the waste gas through the filter screen, the movement of the air flow may cause the dust to accumulate on the bottom surface of the filter screen. With the extension of the use time, the filtering effect of the filter screen will be reduced, affecting the efficiency of waste gas treatment.

[0004] Therefore, it is necessary to provide an industrial waste gas treatment device based on plasma technology to solve the above technical problems. UTILITY MODEL CONTENTS
