Atmospheric pressure low temperature plasma air purifying device

Abstract

The invention discloses an atmospheric pressure low temperature plasma air purifying device. The atmospheric pressure low temperature plasma air purifying device comprises a plasma generation zone, agas distribution zone, an external gas source, and an external power source; the plasma generation zone is composed of a high voltage electrode, a grounding electrode, a quartz dielectric-slab, and asealed cuboid chamber; the high voltage electrode and the grounding electrode are arranged in the sealed cuboid chamber in parallel, and are designed to stretch out of the cuboid chamber through a cuboid chamber structure sealing plate, and are connected with the two electrodes of the external power source; the quartz dielectric-slab is embedded into the sealed cuboid chamber; the gas distributionzone is composed of a bottom plate provided with a sieve pore shaped vents and an insulation covering plate, so that gas can be introduced into the plasma generation zone uniformly. According to theatmospheric pressure low temperature plasma air purifying device, air is introduced into the chamber of the plasma generation zone, plasma is generated under the action of a strong electric field; theobtained plasma is abundant in active free particles, air purifying can be realized through contact of the plasma with excellent oxidizability with the external gas.

Description

technical field [0001] The invention relates to an air purification device, in particular to a device for air purification by utilizing plasma technology discharge to generate active particles. Background technique [0002] In recent years, with the development of science and technology, the advancement of industrialization, and the continuous changes in residents' lifestyles, people's material and cultural needs have been greatly enriched. However, serious environmental problems are accompanied by material enjoyment. The discharge of a large amount of gaseous pollutants causes environmental pollution, which brings serious harm to the ecological environment and human health, and has become the focus of attention from all walks of life. For example, the acid rain that has occurred frequently in recent years, and the severe smog that occurs in the north every winter, especially in the Beijing-Tianjin-Hebei region, are all related to these reasons. [0003] Judging from the po...
