Problems solved by technology

However, when the voltage of corona discharge is high, it is easy to form spark discharge. In addition, the intensity of corona discharge is relatively weak, and the efficiency of treating exhaust gas is relatively low.
The dielectric barrier discharge is a

Embodiment Construction

[0024] Such as figure 1 As shown, the high-volume low-concentration plasma waste gas treatment device of the present invention includes a plasma shell 1 . The plasma shell 1 is a cuboid box structure. Its left plate is processed with gradually expanding air inlet 2, its upper plate right portion is processed with tapering air outlet 3, and its front plate is processed with inspection hole 17.

[0025] combine Figure 2 to Figure 4 As shown, 3×4 plasma generators 4 are installed in the same cross section of the inner chamber of the plasma housing 1 between the gas inlet 2 and the gas outlet 3 . That is, three plasma generators 4 are arranged horizontally, and four plasma generators 4 are arranged vertically. The plasma generators 4 are connected to each other along the outer edge and fill up the cross section. The plasma generator 4 is perpendicular to the gas inlet 2 of the plasma housing 1 . combine Figure 5 to Figure 7 As shown, a single plasma generator 4 includes a ...

Abstract

The invention discloses a large-air-volume low-concentration plasma exhaust gas treatment device comprising a plasma shell, wherein an air inlet and an air outlet are arranged on the plasma shell; a plurality of plasma generators are arranged in at least one cross section of the cavity of the plasma shell; the plasma generators in the same cross section are connected with each other; the plasma generators are vertical to the air inlet and comprise insulating bases; air flow uniform grids are connected at the front and rear parts of the bases; a plurality layers of wire electrodes and a plurality of plate electrodes are vertically connected between the left and right plates in the cavities of the bases from top to bottom; the plate electrodes as well as the plate electrodes and the layers of wire electrodes are parallel to each other; each plate electrode is in interleave arrangement with each layer of wire electrodes and has equal space with adjacent wire electrodes; each layer of wire electrodes are uniformly arranged at intervals; each plate electrode and wire electrode are respectively connected with an outgoing wire; and the outgoing wires are respectively connected with the ground terminal and the high voltage terminal of a high voltage alternating current power supply. The large-air-volume low-concentration plasma exhaust gas treatment device disclosed by the invention is capable of obtaining relatively high gas treatment flow, maintaining high-density large-area plasma, discharging in a stable state and improving the treatment efficiency.

Description

technical field [0001] The invention relates to a waste gas purification device, in particular to a high-volume low-concentration plasma waste gas treatment device. Background technique [0002] With the development of the economy, the problem of toxic and harmful gaseous pollution in industrial production and other fields has become increasingly serious. Gaseous pollution mainly comes from petroleum, chemical, painting, sewage treatment, tobacco and other industries. The gaseous pollutants produced by these industries have the characteristics of large flow and complex composition. If they are directly discharged, they will cause serious harm to human health and the atmospheric environment. These pollutants must be processed online with a large flow to meet the national emission standards. [0003] Low-temperature plasma technology is a hot technology in the field of gaseous pollutant control in recent years. Compared with traditional air purification technologies, such a...
