High-voltage pulse plasma sterilizer for BMB graphite brush

Abstract

The invention relates to a plasma sterilizer, in particular to a high-voltage pulse plasma sterilizer which generates an ultra-high voltage at the tail end of a graphite brush by using a transient high voltage and ejects high-energy electrons for damaging bacteria structures. The high-voltage pulse plasma sterilizer for the BMB graphite brush comprises a columnar shell and a plasma generator arranged in the columnar shell, wherein when the plasma generator is placed in a groove, an ionic group output opening of the graphite brush on the plasma generator just faces a stainless steel mesh enclosure of an upper shell of the columnar shell. When in use, the plasma generator generates the ultra-high voltage at the tail end of the graphite brush by using a pulse mode to enable the tail end to emit electrons with high energy, which can eliminate bacteria in air so as to greatly lower the cost. Meanwhile, the plasma sterilizer can not produce any residues and not cause secondary pollution, and save energy sources.

Description

technical field [0001] The invention relates to a plasma sterilizing device, in particular to a BMB graphite brush high-voltage pulse plasma sterilizing device which generates ultra-high voltage at the end of a graphite brush with an instantaneous high voltage and shoots high-energy electrons to destroy bacterial structures. Background technique [0002] In modern life, people's living and working environments have been greatly improved. People often work, live and travel in buildings and vehicles equipped with central air-conditioning systems. In order to save energy and maintain a comfortable temperature, this type of Buildings and vehicles usually have high airtightness, so in a nearly closed environment, the flow of air is mainly realized by the operation of the central air conditioner, so that the air circulates continuously in the closed environment, due to the circulation In the air, the new air is only about 20%. Therefore, as time goes by, affected by people's activ...

Problems solved by technology

[0003] In order to improve the air in the above-mentioned environment, people have adopted many ways to kill bacteria in the air and eliminate harmful substances to reduce air pollution. At present, the main methods used are: 1) air filtration method, which is installed in the pipeline of central air conditioning Porous filter material can filter the dust in the air to purify the air, but the porous filter material will increase the resistance of air flow, and with the prolongation of use time, its filtering effect will decrease, if it is not replaced in time, it will It will aggravate air pollution and even produce secondary pollution; 2) Electrostatic dust removal method, by discharging the circulating air, the dust in the air is charged, and then the dust collection device is used to collect the charged dust to achieve the purpose of purifying the air , but this method cannot kill bacteria in the air, and it is inconvenient to set up and use; 3) Ultraviolet sterilization method uses ultraviolet rays (UVC) to kill germs in the air, but it can do nothing to the dust in the air and cannot purify 4) Plasma sterilization method, through the high-energy electrons generated by the plasma generator, ionizes the air and then acts on the germs and pollution sources in the air to achieve sterilization and dust removal purification Effect

[0004] Because the structure of the existing plasma generator is mainly a multi-polar plate structure (such as: plate-to-plate type, wire-plate type, for plate type, wire barrel type), this type of generator is due to the complex structure, and the plasma The density is small, the air purification speed is slow, and the sterilization and purification effect is not ideal
