Dust collection device of electrostatic-type air purifier

Abstract

The invention relates to a dust collection device of an electrostatic-type air purifier. The dust collection device comprises an upper cover, a lower cover and clamping plates which are arranged between the upper cover and the lower cover and are provided with a plurality of slots, polarized electrodes are arranged in the dust collection device, a high-voltage generator is arranged on the inner side of the upper cover, an electric field module is correspondently arranged in each slot, each electric field module comprises a plurality of electric field positive pole pieces and electric field negative pole pieces, which are alternately arranged in parallel, each electric field positive pole piece is connected to a positive conductive plate, each electric field negative pole piece is connected to a negative conductive plate, and the distance between each electric field positive pole piece and the adjacent electric field negative pole piece is 3.0mm to 4.0mm; a high-voltage output end of the high-voltage generator is connected to the positive conductive plate of each electric field module through a high-voltage plate connection terminal, a ground output end of the high-voltage generator is connected to the negative conductive plate of each electric field module through a grounding plate connection terminal which is grounded; each polarized electrode is an ion generator. When the dust collection device is applied to the electrostatic-type air purifier, a purification effect of no ozone, no discharging noise during dust collection, extremely low requirement on voltage and low requirement on insulation property can be achieved.

Description

technical field [0001] The invention belongs to the magnetic or electrostatic separation of solid materials from solid materials or fluids; the technical field of high-voltage electric field separation, and particularly relates to a method that can achieve ozone-free, discharge-noise-free dust collection and extremely low voltage requirements by rationally setting the structure. Dust collection device for electrostatic air cleaners with greatly reduced insulation requirements. Background technique [0002] With the development of economy, the progress of society, and the continuous improvement of human civilization, people's work, study, entertainment and other activities are more and more transferred from outdoor to indoor. Scientific research shows that indoor pollution is 5 to 10 times that of outdoors. On average, urban and rural residents in my country spend 70% of their time indoors, and in cities, this value is even as high as 80% to 90%. The Environmental Health Org...

Problems solved by technology

[0006] The technical problem solved by the present invention is that in the prior art, because the traditional electrostatic air cleaner needs to apply a high voltage of 6KV to 8KV to the electrostatic dust collection device, the insulation requirements for other components in the dust collection device are very high, and Traditional electrostatic air purifiers use tungsten wire and other materials as polarized electrodes, which will generate a large amount of ozone, resulting in more complicated process control, which makes the failure rate of traditional electrostatic air purifiers higher, and the electrostatic dust collection device works Strong discharge noise may be generated in the air, and if this type of air purifier does not have a deozone device, the ozone released will far exceed the national standard GB / 18202-2000 that "the concentration of indoor air ozone in one hour should be 0.16 mg / m 3 The following "requirements, and then provide a dust collection device for an electrostatic air cleaner with an optimized structure
