Plasma treatment method for effectively purifying high-temperature waste gas

Abstract

The invention discloses a plasma treatment method for effectively purifying high-temperature waste gas. The method comprises the following steps carried out in sequence: ejecting refrigerated air through a connecting pipeline, an air passage of a mounting ring and an air outlet nozzle into an air inlet through an air cooler; enabling the high-temperature waste gas to enter and be combined with cold air to realize a quick cooling effect; enabling the cooled waste gas to pass through a low-temperature plasma electric field tube; enabling the waste gas to pass through an ultraviolet lamp and exhausting from an air outlet; enabling the waste gas exhausted from the air outlet to pass through an ultrasonic atomization device to fuse atomization liquid with the waste gas, so as to purify the waste gas. The plasma treatment method is used for solving the problems that, when a high-temperature gas is subjected to conventional purification treatment, the favorable purification effect cannot be realized and moreover the damage can be caused to an internal component in the prior art; the invention provides the plasma treatment method for effectively purifying the high-temperature waste gas, and when being applied, the plasma treatment method can be used for effectively treating the high-temperature waste gas, is used for carrying out destructive purification on the molecule of the waste gas, is good in effect, is used for removing smell and deodorizing, and is wide in scope of application.

Description

technical field [0001] The invention relates to waste gas treatment, in particular to a plasma treatment method for effectively purifying high-temperature waste gas. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially chemical plants, steel plants, pharmaceutical plants, coking plants, oil refineries, etc., and the production of domestic waste gas from human life, the exhaust gas has a strong smell, which seriously pollutes the environment and affects human health. Therefore, when exhaust gas is discharged, purification treatment is required. Nowadays, the functions of exhaust gas purification devices are relatively single, and the treatment effect is poor. Generally, it is only simple filter adsorption, which cannot achieve a good purification effect, and it is difficult to replace the internal filter element, resulting in inconvenience. , especially some high-temperatur...
