Description
Technical field
The utility model belongs to field of air filtration, specially a kind of air filter unit.
Background technology
Air filter arrangement includes air duct, installation the first air cleaner in the air passageway, wherein first
Air cleaner includes filter frame and filter body, and the filter frame is provided with least one for air circulation
Passage, the filter body include can electrostatic charging fiber, can electrostatic charging fiber be attached to filter frame so that filter sheet
Body is realized being located at the downstream one away from filter frame to the intended flow direction for flowing through air duct relative to air from filter frame
Extension at set a distance position.When air flows through a first air filter of the above-mentioned kind, between the fiber in filter body
Generation is mutually shifted, so that rubbing against one another.Produced friction when air flows pass the fibres makes fiber keep electrostatic charging.This species
The air cleaner of type is separated particulate with air by electrostatic interaction and mechanism.The spy of such air cleaner
Levy is that pressure drop on air cleaner during the service life of filter is basically unchanged.So as in the service life of filter
Period is by the air-flow of air cleaner by substantially constant.However, capture and keep the quantity of particulate on the fiber surface with
The passage of time and be continuously increased, this causes to reduce for the fiber surface for capturing follow-up particulate by electrostatic interaction.Therefore
The separating degree of air cleaner increasingly reduces.The quality of the clean air for thus being obtained by air cleaner is increasingly reduced.When
It is necessary to change a new air cleaner during acceptable level that separating degree is minimized.
In order to solve the above-mentioned technical problem, Chinese patent CN101505876B discloses " air filter arrangement and its system
Make method " include：Air duct；The first air cleaner in the air passageway is installed, first air cleaner includes
Being provided with least one is used for the filter frame of passage of air through-flow, and first air cleaner is also included can be electrostatic charging
The filter body of fiber, it is described can electrostatic charging fiber be attached to filter frame so that filter body is realized from filter
Framework is located at the extension at the certain distance position of filter frame downstream to the intended flow direction that air duct is flowed through relative to air,
The air filter arrangement includes the second air cleaner, and second air cleaner includes filter cloth, in the mounted state
The filter cloth is suitable for extending across air duct, so that along the air for longitudinally substantially flowing through filter cloth in air duct, and
And the intended flow direction of the second air cleaner installation air with respect to air duct in the air passageway is located at
At the position in the first air cleaner downstream.And for example Chinese patent CN100346836C discloses a kind of " air filtering that was used for
Microbiocidal air filter ", it has a）One housing unit for forming an air duct, b）One air filtering assembly, c）
One air inlet, d）One gas outlet, wherein the air filtering assembly includes a microbiocidal air filter element, the air mistake
Filter component is configured to so that the air duct of ventilating air crosses through micro- life between air inlet and gas outlet
Thing type air filter element, it is theed improvement is that, the air filtering assembly includes a upstream filter element and a downstream
Filter element, the microbiocidal air filter element is arranged between the upstream and downstream filter element, so that
Air duct for the ventilating air between the air inlet and gas outlet crosses through each air filter element, it is described on
Trip and air downstream filter element are microbiocidal air filter element and include a kind of demand type disinfectant resin, should
Demand type disinfectant resin is a kind of iodate strong basic anion-exchange resin.
But above-mentioned technical proposal can neither extend the high efficiency filter that the service life of element can not be realized to air again.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of air filter unit, it can be realized to Efficient air
Filtering, can also realize the effective protection to component.
To realize above-mentioned technical purpose, the specific technical scheme that the utility model is taken is, a kind of air filter unit,
It carries air inflow end, air outflow end, filter medium and the supporting part for supporting filter medium, the supporting part
It is arranged between air inflow end and air outflow end；Spraying is installed towards the side of air inflow end in filter medium to occur
Device, and mist generating device send spraying be located at air from the path that air inflow end flows to filter medium.
Used as the improved technical scheme of the utility model, the filter medium includes the ground floor filter cloth being sequentially overlapped
Layer, filter fiber layer and second layer filtering layer of cloth.
Used as the improved technical scheme of the utility model, the consistency of ground floor filtering layer of cloth is less than in the filter medium
The second layer filters the consistency of layer of cloth.
Used as the improved technical scheme of the utility model, the filter medium is in rugosity.
Used as the improved technical scheme of the utility model, the bore of air inlet one end of the air inflow end is less than air
End is flowed near one end of filter medium.
Used as the improved technical scheme of the utility model, the inwall of the air inflow end is covered with dismountable fiber cloth.
As the improved technical scheme of the utility model, third layer filter cloth is additionally provided with air outflow end.
Beneficial effect
Mist generating device is provided with by the one end in air inlet, the gravity for aggravating particulate in air using spraying makes to have leisure
Solid particulate matter lands automatically in gas, realizes the preliminary filtering to air, also causes air air when filter medium is touched
In particulate can be adsorbed in filter media surface, its not only fully realize to filter medium protection again realization to the abundant of air
Filter, and air cleaner is also easily cleaned, and effectively extends the service life of air cleaner.
