Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a plasma waste gas treatment system. Background Art

[0002] A considerable amount of waste gas will be generated in the preparation and molding of quartz, so a corresponding waste gas treatment system is required. At present, the main way to treat waste gas is to add natural gas to the waste gas for combustion treatment. This treatment method requires supporting equipment, pipelines and corresponding monitoring systems, and the investment is large; it also consumes a lot of natural gas and electricity (exhaust to a high place); it cannot remove SiO2, and requires a bag filter, which also requires corresponding supporting equipment, which increases the investment and operating costs; it cannot remove HF and F2, and requires an HF cleaning tower;

[0003] After searching, the application with patent number CN202021337383.9 discloses a low-temperature plasma organic waste gas treatment system, which can reduce the risk of explosion and improve the safety of the waste gas treatment process, including a low-temperature plasma reactor, a temperature sensor, a total hydrocarbon sensor and a controller; the temperature sensor is used to collect the gas temperature T in the low-temperature plasma reactor; the total hydrocarbon sensor is used to collect the total hydrocarbon concentration C of the gas in the low-temperature plasma reactor; the controller is used to control the low-temperature plasma reactor to shut down when the gas temperature T or the total hydrocarbon concentration C exceeds the corresponding safe operating range;

[0004] The above application documents treat the waste gas through a plasma waste gas reactor, which can effectively avoid the occurrence of the above problems. However, there are tar, by-products, particulate matter and other substances that adhere to the electrodes for a long time in the plasma reactor. If they are not cleaned in time, the dielectric constant of the electrode or the electrode blocking medium may change, which may easily cause fire due to local overheating. In addition, the concentration of flammable and explosive substances continues to increase, which can easily cause combustion and explosion.

[0005] Therefore, we propose a plasma exhaust gas treatment system. Utility Model Content
