Problems solved by technology

[0005] At present, most of the indoor gas purification devices on the market adopt the principle of physical adsorption, and its treatment effect is limited by the properties of the adsorbent and is not very obvious. At the same time, the adsorbent needs to be replaced regularly after the adsorption is saturated, which makes its application have certain limitations. sex

Abstract

The invention discloses an indoor gas purification device based on discharge plasma, comprising a shell provided with a gas inlet and a gas outlet, wherein a fan, a dielectric barrier corona discharge processing region and a dust collecting region are arranged in the shell between the gas inlet and the gas outlet. According to the indoor gas purification device, more uniform low-temperature plasma is generated by two discharge units which are arranged oppositely, oxidation processing is carried out on harmful gas in the dielectric barrier corona discharge processing region, heteropolarity charge electrocoagulation and processing are carried out on inhalable particles, the inhalable particles are collected in the dust collecting region, and the device has the advantages that no chemical agent and no physical additive are used, no special gas atmosphere exists, the energy consumption is low, indoor gas purification is realized under barometric pressure, and the effect is good.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification devices, and relates to an indoor gas purification device based on discharge plasma. Background technique [0002] At present, with the rapid development of the economy, the problem of air pollution has attracted extensive attention from the industrial and scientific circles. However, compared with the outdoor air pollution, the indoor air pollution has generally not received much attention. But in fact, people spend more than 80% of their time indoors every day, and the air they breathe mainly comes from indoors. Indoor air pollution will directly threaten human health. With the development of industry and the improvement of people's living standards, various building decoration materials, furniture, and daily chemicals are pouring into the room, and the sources and types of indoor air pollutants are increasing day by day, causing the indoor air pollution level to be higher than t...
