Embodiment Construction

[0024] like figure 1 , figure 2 As shown, a combined plasma device includes a casing 3, an air inlet 4 and an air outlet 8, and also includes: a corona discharge system, a double dielectric barrier discharge low-temperature plasma system, a power supply system, a high-voltage conversion system, and an air distribution and diversion system 9. Spray flushing system.

[0025] Among them, the corona discharge system includes a plurality of corona discharge discs 2, which are provided with positive and negative electrodes, and are externally connected with a high-voltage direct current power supply. The plate-type precipitation electrode is grounded, and the negative pole of the power supply is output to the discharge electrode placed in the center of the plate-shaped electrode. The corona section uses the principle of electrostatic capture to firstly remove particulate matter and mist water droplets in the exhaust gas.

[0026] The dual-dielectric barrier discharge low-tempera...

Abstract

The invention relates to the technical field of waste gas purification, and particularly relates to combined plasma equipment. The combined plasma equipment comprises a housing, an air inlet and an air outlet, and further comprises a corona discharge system, a double-dielectric barrier discharge low-temperature plasma system, a power supply system, a high-voltage conversion system, an air distributing and guiding system and a spraying and washing system. The corona discharge system is close to the air inlet, and comprises a plurality of corona discharge trays, wherein the corona discharge trays are arranged and placed in the housing in multiple rows; the double-dielectric barrier discharge low-temperature plasma system is close to the air outlet and comprises a plurality of low-temperature plasma discharge trays, wherein the low-temperature plasma discharge trays are arranged and placed in the housing in multiple rows. According to the combined plasma equipment, by adopting a structure of combining the corona discharge system and the double-dielectric barrier discharge low-temperature plasma system, waste gas pollutants are effectively treated, and purified gas can meet an environment protection requirement.

Description

technical field [0001] The invention relates to the technical field of waste gas purification, in particular to a combined plasma device. Background technique [0002] Industrial waste gas discharged by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without treatment and reaches the standard, the quality of the atmospheric environment will inevitably decline, causing serious harm to human health and causing huge economic losses to the national economy. loss. [0003] At present, the emission standards of exhaust gas pollutants are strict, and they must be purified to a certain standard before they can be discharged. The existing waste gas treatment methods include photochemical oxidation, combustion, absorption method, adsorption method, biological method, etc. to treat gaseous pollutants. Although these methods have relatively high efficiency in removing waste gas, due to...
