Description
Technical field
The utility model relates to air cleaner field, is related specifically to a kind of electro static filtering apparatus for PM2.5 particle.
Background technology
Room air pollution source can come from many-side, the such as direct air pollution from outdoor, indoor mould growth, indoor and outdoor pollen and indoor oil smoke etc.These air pollutions have gaseous state and aerosol state (particle suspension), and Environmental Protection Agency (EPA) has clear and definite standard for the quality of air.Particle suspension can be detrimental to health, especially PM2.5 particle directly can enter lung, this type of air pollution can cause asthma, chronic lung disease and cardiovascular disease etc., improve air quality, reduce the particle suspension in air, especially reduce PM2.5 granule density and can effectively improve crowd's body health especially.
Traditional indoor air cleaner adopts high efficiency filter film (HEPA filter membrane) for the filtration of PM2.5 particle more, but the air permeance resistance of HEPA filter membrane is excessive, needs powerful blower fan, and not only noise is large, and is unfavorable for energy-conservation.And prolongation in time, clearance of particles efficiency can decline thereupon, and air permeance resistance is also increasing, and need periodic replacement, cost is higher.If the ozone of high concentration can be produced again by high-voltage corona technology and impair one's health.
Utility model content
For deficiency of the prior art, the utility model provides a kind of energy-conserving and environment-protective and can not produce the electro static filtering apparatus for PM2.5 particle of high-concentrated ozone.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of electro static filtering apparatus for PM2.5 particle, it is characterized in that: comprise two-layer conductive fiber layer, one deck high-dielectric coefficient nonwoven fabric and the DC high-voltage source module with fine air permeability, described high-dielectric coefficient nonwoven fabric is located between two-layer conductive fiber layer; Also be respectively equipped with two pieces of insulation grids for supporting two-layer conductive fiber layer at the two ends, outside of described two-layer conductive fiber layer, these two pieces insulation grids are fixedly connected with two-layer conductive fiber layer respectively; The output of described DC high-voltage source module is connected with two-layer conductive fiber layer respectively.
Further, described conductive fiber layer is conductive fibre fabric or conductive fiber paper.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model arranges one deck high-dielectric coefficient nonwoven fabric in two-layer conductive fiber layer, structurally constitute a capacity plate antenna, when high pressure being added to conductive fiber layer by DC high-voltage source module, ultra tiny nonwoven fabric is polarized, the effect of similar foil electret can be provided, and this device solves the electric charge exhaustion problem of electret well, the very big like this service time extending ultra tiny nonwoven fabric, ultra tiny nonwoven fabric simultaneously in this device is designed to detachably, can wash and further save cost of use, PM2.5 clearance of particles efficiency is high.
2, the utility model adopts the ultra tiny nonwoven fabric of similar electret filter film, and not only air permeance resistance is little, does not need high-power blower, uses noise low, good energy-conserving effect, and the good purification to air.
3, ultra tiny nonwoven fabric of the present utility model is polarized, the effect of similar foil electret can be provided, and this device solves the electric charge exhaustion problem of electret well, substituted for the disposable filter membrane (HEPA filter membrane) of cost intensive in routine techniques, reduce cost, and avoid the decline of the air particles clearance rate caused because changing filter membrane not in time.
4, the utility model adopts insulation lattice support conductive fiber layer, makes filter both firm, plays again the effect of insulation, improve the security of use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the electro static filtering apparatus for PM2.5 particle described in the utility model.
