Fresh air filtering device combining negative-ion generator with static electret

Abstract

The invention discloses a fresh air filtering device combining a negative-ion generator with a static electret. The fresh air filtering device comprises the negative-ion generator, a charging and agglomerating air pipe, an air filtering box body, a plate type static electret filter, a bag type static electret filter, a controller and a particle concentration sensor, wherein the negative-ion generator is located in the charging and agglomerating air pipe which is connected to the air filtering box body; the plate type static electret filter and the bag type static electret filter are located inthe air filtering box body; and the controller is separately connected to the negative-ion generator and the particle concentration sensor. According to the fresh air filtering device disclosed by the invention, the particles are charged and agglomerated in the charging and agglomerating air pipe and double static filtration is carried out through the plate type static electret filter and the bagtype static electret filter, so that the particle filtration efficiency is improved effectively, and meanwhile, the filtration resistance is reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of ventilation, and relates to a high-efficiency and low-resistance fresh air filter device combined with an anion generator and an electrostatic electret. Background technique [0002] The concentration of outdoor particulate pollutants in domestic smog weather is getting more and more serious. At present, traditional air filtration and purification devices such as mainstream air purifiers and air filters in my country can effectively remove particles with larger particle sizes in the air, but cannot effectively intercept particles with smaller particle sizes. As the concentration of outdoor air pollutants seriously exceeds the standard and many users require air filtration devices to operate with large air volume and high filtration speed, traditional air filtration devices are far from meeting the requirements of high concentration and high filtration speed particulate pollutants. There are problems such...
