Dielectric Barrier Low Temperature Plasma Air Purifier

Abstract

The invention discloses a dielectric barrier low-temperature plasma air purifier which comprises an insulation tube. Metal conductive paint is sprayed to the inner wall of the insulation tube, a quartz tube is arranged at one end in the insulation tube, and a honeycomb aluminum cold accelerant filter screen, a honeycomb aluminum photocatalyst filter screen and a metal needle are sequentially arranged in the quartz tube; and a PTC heater, an activated carbon filter screen and honeycomb aluminum are sequentially arranged at the other end in the insulation tube, the honeycomb aluminum is externally connected with the negative electrode of a high-voltage pulse power source, the honeycomb aluminum photocatalyst filter screen is externally connected with the positive electrode of the high-voltage pulse power source, and netty insulation covers are embedded to the two ends of the insulation tube. Under the action of the high-voltage pulse power source, the quartz tube can carry out dielectric barrier silent discharge to generate plasma, bacteria in the air are killed, and impurities and harmful gas in the air are decomposed; and ozone generated in the discharge process can be reduced into oxygen through the PTC heater, the purifier works under normal temperature and normal pressure, is free of noise, and generates no secondary pollution, and the good purifying effect is achieved.

Description

technical field [0001] The invention relates to an air purifier, in particular to a medium barrier low-temperature plasma air purifier. Background technique [0002] According to the survey data of the China Indoor Environment Testing Center, the indoor air pollution of civil and commercial buildings in my country is 5 to 10 times higher than the outdoor ambient air pollution, and in some special places it is even more than 100 times. The number of deaths due to indoor air pollution is more than 100,000 in my country every year. Indoor air pollution not only seriously affects people's health and normal life, but also causes huge economic losses to our country. [0003] With the continuous improvement of the consumption concept of Chinese urban consumers, products that can produce clean air for consumers will gradually sell well. [0004] According to the working principle of air purifiers, air purifiers can be divided into two categories. The first category is passive purif...

AI Technical Summary

Problems solved by technology

In this invention, "under the action of the fan, the external air enters the area where the plasma components are located from the air inlet at the lower part of the purifier" uses a fan, so the overall noise is relatively large

Because the plasma discharge produces ozone, the invention does not treat the ozone, so it will produce ozone pollution

[0008] The invention patent with the patent number 200810201579.2 discloses a low-temperature plasma purifier. The invention adopts dielectric barrier plasma technology and works under normal temperature and pressure without noise. However, the electrode arrangement used cannot generate ion wind
