A high-efficiency air cleaner electrostatic dust removal device, as shown in Figure 1, said dust removal device includes a case cover 4, a casing 1, a HEPA high-efficiency filter screen 19, anion generator 2, dust collector 3, activated carbon 20 and resistance detection Instrument 21, the box cover is detachably sealed and arranged on the box body, the box body is hollow with two ends open, one end open end of the box body is set as air inlet 6, and the other end open end of the box body Set as the air outlet 5, the HEPA high-efficiency filter screen, the negative ion generator, the dust collector and the activated carbon are arranged vertically and coaxially at intervals successively in the box, and the HEPA high-efficiency filter screen is set in the box near the air inlet side, and the HEPA high-efficiency filter screen is arranged on the side near the air outlet. Activated carbon is set in the box, and the dust collector can absorb dust and other particles with negative ions. The negative ion generator is connected to the dust collector. The negative ion generator is the negative high voltage end, and the dust collector is the positive high voltage end. Both ends of the dust collector close to the inner wall of the box are connected with a resistance detector, which can detect the change of the resistance value of the dust collector. In this embodiment, the negative ion generator and the dust collector The distance between them satisfies the condition ≥1.5cm/kv.

Since the air to be purified may be mixed with impurities at the molecular level with smaller particle sizes, such as organic matter and other impurities with peculiar smells, these impurities at the molecular level with smaller particle sizes cannot be cleaned by negative ion generators and dust collectors. What is adsorbed and removed will seriously affect the dust removal and odor removal effect of the dust removal device. The setting of activated carbon can almost completely remove these molecular-level impurities and further improve the odor removal effect of the dust removal device.

The resistance detector can detect the change of the resistance value of the dust collector. Due to the long-term use of the dust collector, a large amount of dust, particles and other impurities will be adsorbed on the dust collector, which will not only form wind resistance, reduce the efficiency of dust removal, but also affect The effect of dust removal reduces the effect of dust removal. Due to the setting of the resistance detector, the change of the resistance of the dust collector can be detected at any time, so that the user can know the replacement or cleaning of the dust collector in time.
