Beneficial effects of the present invention are：The present invention's concentrates the device for removing superfine particulate matter in air new based on electric microfield
Wind is inhaled into air inlet, and anion generator connection carbon brush carries out electronics electrophoresis release centered on carbon brush.Charged particle
Fine grained it's too late the bacterium surface in inlet air is adsorbed, makes fine particle and the powered journey negative electrode polarity of bacterium.Carbon brush contacting pipe
The aluminium foil figure layer of road inwall, makes tube wall is negatively charged to form negative electrical charge hollow tube.Charged particle thing is passed through in negative electrical charge with air
Blank pipe forms the vortex with 90 degree of turning homonymy water around the corner, enters dust receiver as matrix flows backwards angle.Band negative electrode electricity
Superfine particulate matter can be with magnetic induction line displacement to anode electric field side in made positive pole electromagnetic field in the air of field.This
When remove negative electrical charge, neutral superfine particulate matter is rested on the effect for reaching concentrated dust-removing in dust receiver.In having electronic mistake
Cheng Zhong, bacterium is killed by negative electrical charge, is also attached to receiver bottom.Reach the dual purpose of dust and bacteria removing.At receiver bottom
The copper disk line connecting wire in portion exports the negative electrical charge of particle.Fine particle and bacterium lose electrical wall hanging in receiver inwall and
Bottom completes the effect of concentrated dust-removing sterilization.Clean air flows backwards angle by matrix and exported, into exhaustion section.Negative electrical charge is in metal
Air is exported at anion catcher leads to many ground wires and lead and remove.Each electronic component is carried out Reasonable Regulation And Control by the present invention, makes profit
Reach that dust-collection sterilization is optimized in the process of running with electric microfield concentrated dust-removing, there is no filtering dust net, for indoor ultra-fine
Grain thing, flue gas, dust, the nanoscale fine particle of bacterium are adsorbed, and effectively reduce the kinetic energy parameters of blower fan, electrical loss
It is few, improve the effect of sterilization, environmental protection.Avoid inside is unclean for a long time from easily causing filter to block and parasitic largely thin
Bacterium, the problem of triggering personnel's breathing problem.Mechanical loss is small, and service life is long.There is windage to surpass compared to market air cleaner
The low economic characteristics of small, power consumption.
