The utility model has also disclosed a kind of dust catcher, and described dust catcher is provided with above-mentioned electrostatic precipitator.
Below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is described in detail.
As shown in Figure 1, the utility model has disclosed a kind of electrostatic precipitator, comprise air inlet 1, exhaust outlet 3, accumulation area 2, air inlet 1, exhaust outlet 3 are oppositely arranged, accumulation area 2 is arranged between air inlet 1 and exhaust outlet 3, air with dust enters from air inlet 1, and it is for clearance that dust falls into accumulation area 2 etc. after by dust removal process, and the pure air of removing after dust is also discharged from exhaust outlet 3.
Existing dust catcher by vacuum namely negative pressure small particle is sucked to dust-collecting box, and in the exhaust ports of dust-collecting box, filter screen is housed, thereby dust is stayed in dust-collecting box.This its vacuum of existing dust catcher produces by the driven by motor vortex flow fan, the rotating speed of fan need to be up to 20000 rev/mins, and common motor does not reach this rotating speed, therefore, the motor of dust catcher of the prior art adopts series machine because its rotating speed is high, so the noise produced is just large, the noise of general dust catcher, at 85 decibels, doubles than refrigerator.Due to its generation be high-frequency noise, the people sounds also and relatively feeling bad.
In order to solve the above-mentioned technical problem existed in prior art, in the utility model preferred embodiment, between air inlet 1 and exhaust outlet 3, also be provided with at least one group of anodal electroplax 5 be oppositely arranged and negative pole electroplax 6, the gap of arranging of anodal electroplax 5 and negative pole electroplax 6 is consistent with the wind direction of air inlet 1, as shown in Figure 2.During work, enter from air inlet 1 with the air of dust, pass the gap of arranging between anodal electroplax 5 and negative pole electroplax 6, finally from exhaust outlet 3, discharge.
