Technical Field

[0001] The utility model relates to the technical field of industrial waste gas treatment, in particular to an injection type low-temperature plasma reaction device. Background Art

[0002] Low-temperature plasma reaction refers to the use of external voltage to ionize gas molecules to form low-temperature plasma. Low-temperature plasma degradation of pollutants utilizes these high-energy electrons, free radicals and other active particles to interact with pollutants in the exhaust gas, causing the pollutant molecules to decompose in a very short time, thereby achieving the purpose of degrading pollutants in industrial exhaust gas.

[0003] The Chinese patent discloses an injection-type low-temperature plasma integrated system, with the announcement number CN210752007U, which includes a low-temperature plasma high-pressure reaction box, a fan is arranged inside the low-temperature plasma high-pressure reaction box and at the air inlet, and an ionization generation module is arranged between the air outlet of the low-temperature plasma high-pressure reaction box and the air outlet side of the fan; an ion air mixer extending into the waste gas collection pipe is fixed on the outer wall outside the low-temperature plasma high-pressure reaction box, and the ion air mixer is provided with a plurality of vents, and at least one ion air outlet is arranged on the outer wall of the vent, and the air inlet of the vent is connected to the air outlet of the low-temperature plasma high-pressure reaction box. The injection-type low-temperature plasma waste gas treatment system can treat the waste gas generated in the production process of various industries such as the tobacco industry and the rubber processing industry, and the gas treated by the device can meet the emission standards.

The long-term operation of the device increases the probability of equipment failure. Therefore, we propose an injection-type low-temperature plasma reaction device to solve this problem.
