Plasma air purification device and method

Abstract

The invention discloses a plasma air purification device. The plasma air purification device comprises a plasma generator, an airflow drive device and an outer power source. The plasma generator is composed of high-voltage electrodes, grounding electrodes, quartz tubes and a cuboid cavity structure. The high-voltage electrodes and the grounding electrodes are inserted in the quartz tubes, and thequartz tubes are reversely embedded in the cuboid cavity structure in parallel. When the device works, air enters the plasma generator through an insulating plate with sieve-hole-shaped ventilation holes under the action of an air suction fan, air is ionized under the action of a strong electric field, and plasma is formed. A large number of active free particles are contained in the plasma and make contact with the outside gas through strong oxidability of the active particles, and the purpose of air purification is achieved. The capability of air purification through the device can be adjusted through adjustment on power parameters or fan rotation speed, and different work parameters can be provided according to different pollution situations.

Description

technical field [0001] The invention relates to an air purification device and method, in particular to a device and method for air purification using plasma technology discharge to generate active particles. Background technique [0002] With the improvement of living standards and the acceleration of industrialization, people are paying more and more attention to their own health, especially the rise of the decoration industry, which makes people pay more attention to their living environment. In the room, people will increase the incidence of leukemia, aplastic anemia and other diseases due to the inhalation of harmful substances such as formaldehyde, benzene, TVOC, ammonia and radon in the decoration materials. [0003] The main means currently used in indoor air pollution control include ventilation, filtration, chemical disinfection, ozone disinfection, ultraviolet disinfection, etc. However, these technologies have their own shortcomings and deficiencies. The effect...

However, these technologies have their own shortcomings and deficiencies

The effect of filtering and purifying air is better, but to achieve the same level of cleanliness, the input cost is higher than other disinfection methods; ultraviolet disinfection has a better effect on bacteria inactivation, but the inactivation effect on mold is average, and has harmful effects on the human body. Certain hazards, "dynamic disinfection" cannot be achieved; fumigation disinfection has a relatively good sterilization effect, but the chemical reagents used are toxic, which is very harmful to the human body, and requires a long unmanned ventilation time after disinfection , so it can only be used as a regular disinfection method
