Problems solved by technology
However, this method cannot effectively remove harmful gases such as VOCS in indoor air
Negative ions can reverse the two levels of electrical properties on the surface of bacterial proteins, promote the death of bacteria, and achieve the purpose of disinfection and sterilization. However, this method cannot completely remove dust from the room, and cannot effectively degrade organic pollutants.
Photocatalysis can effectively remove organic pollutants in indoor air and kill microorganisms, but it cannot solve the problem of suspended solids in indoor air and fine particles that are very harmful. At the same time, the micropores of the catalyst are easily blocked by dust and particles. catalyst deactivation
Low-temperature plasma technology can effectively remove suspended particles and organic pollutants in the room, but it has the disadvantage of low purification efficiency

The present invention discloses indoor air purifying method with introduced magnetic field, and is especially low temperature plasma method with introduced magnetic field for purifying indoor air. The corona discharge plasma with introduced magnetic field is used to eliminate harmful suspended particles from air. There are pre-charging dust collecting electrode with earthing-dust colleting plate and pre-charging pin, negative ion discharge pin, and high voltage dust collecting plate separated from the earthing-dust colleting plate by 1.5-2.0 cm. Across the pre-charging dust collecting electrode, voltage of 6-6.5 KV is applied and permanent magnets are set. The present invention eliminates harmful gas from air with pulse discharge plasma with introduced magnetic field. The present invention has several times raised dedusting efficiency, and produces negative ion with the dust collecting power supply.
Description
technical field [0001] The invention belongs to the intersection field of the electrical field and the field of environmental protection, and relates to an air purification method, in particular to a low-temperature plasma indoor air purification method by introducing a magnetic field. technical background [0002] At present, indoor air purification methods mainly include adsorption, static electricity, negative ions, photocatalysis, and low-temperature plasma. The adsorption method is to use certain substances with adsorption capacity such as activated carbon, Al 2 o 3 Adsorbents such as silica gel and molecular sieve absorb suspended solids and a small amount of harmful substances in the air, so as to achieve the purpose of eliminating harmful pollutants. However, this method cannot eliminate the odor, pathogenic bacteria, viruses, microorganisms and air pollution caused by decoration in the indoor air. At the same time, it has the disadvantages of causing secondary pol...
