Abstract

The utility model relates to an air purifying filter screen, which is mainly composed of an electret fiber screen, a supporting framework, a plate-shaped activated carbon and an adhesive agent which are adhered together. The electret fiber screen is attached on the supporting framework; the plate-shaped activated carbon is adhered on the lower side of the electret fiber screen and the supporting framework. The structure has the functions of purifying dust, removing bacteria, adsorbing organic gas and catalyzing and converting inorganic harmful gas and has the advantage of combining adsorption, decomposition and filtering as a whole. The utility model better solves the single purifying performance of purification materials at present. The utility model has the advantages of high efficiency, convenient operation, easy change and repeated use. The utility model is suitable for large purifying devices, such as an air conditioner, an air purifier, etc.

Description

The air cleaning filter screen

The utility model relates to a kind of filter screen, and especially a kind of air cleaning filter screen belongs to air purification field.

At present, employed air cleaning filter screen belongs to single purifying property more on the market, disposable use, and its detergent power is poor, uses also inconvenience, and the material of these filter screens easily causes secondary pollution on the device in dynamic source, and windage can not be stablized control.A kind of air purifying plate is arranged, and its structure comprises filter course and adsorption layer, and this purification plate can purify air effectively, but it can only dedusting, and can not catalysis, decompose airborne pernicious gas, effect is not very good.

The purpose of this utility model is to provide a kind of can reach the high-performance new type purification filter screen that integrates absorption, catalytic decomposition, filters, this filter screen purification efficiency height, easy to use, be easy to change, reusable.

For achieving the above object, the air cleaning filter screen is mainly by electret fiber net, support frame, tabular activated carbon, cementing agent be combined into; The electret fiber net be attached to support frame above; tabular activated carbon by cementing agent be bonded in electret fiber net and support frame below; tabular activated carbon is made up of catalyst and grain active carbon; it can make tabular; also can design the eyelet of different shape onboard; cementing agent can vertically be painted some strips along tabular activated carbon, and electret fiber net and support frame and tabular activated carbon are sticked together.

Can produce following good effect after adopting said structure, dust in can absorbed air, airborne pernicious gas can be decomposed simultaneously, change into the gas that human body is safe from harm, reach the effect that thoroughly purifies air, can be used for various devices such as Household Air Purifier and air-conditioner, warm-air drier.

Be described in further details below in conjunction with drawings and the specific embodiments.

Fig. 1 is a longitudinal sectional view of the present utility model;

Fig. 2 is a transverse sectional view of the present utility model;

In Fig. 1 and Fig. 2, electret fiber net 1 is the efficient sorbing material of a kind of lipophile, itself has the dust suction effect, be to make network structure through processing by pp material, and then be processed into corrugated, and so both increase filter area and reduced windage, increased dust containing capacity again, and stability is preferably arranged, be easy to control windage; Support frame 2 is made corrugated by the polypropylene knotless net; its purpose is electret fiber net 1 firm supporting; be easy to and tabular activated carbon 3 combinations; tabular activated carbon 3 is to be made of catalyst and grain active carbon; have organic gas is adsorbed; inorganic pernicious gas is transformed the performance that resolves into innocuous gas; can make tabular generally speaking; also can require the eyelet of design different shape on the plate face according to windage; cementing agent 4 is a kind of harmless tasteless, translucent colloids, and its main effect is to be integral above-mentioned different materials is bonding.

Earlier electret fiber net 1 is attached on the support frame 2, then the cementing agent 4 of translucent colloid is vertically painted some strips along tabular activated carbon 3, then electret fiber net 1 and support frame 2 and tabular activated carbon 3 are in the same place, through pressing they are bonded together, because whole filtering net is to work in an electric field, filter screen respectively has one deck static web plate up and down, when advancing people's filter screen, gas is crossed filtration once by the static web plate on upper strata, therefore, when gas passes from electret fiber net 1, dust is further adsorbed, on electret fiber net 1, when passing through tabular activated carbon 3 again, dust is further adsorbed, pernicious gas is decomposed by tabular activated carbon 3 simultaneously, change into harmless gas, the gas that comes out from tabular activated carbon 3 also will just can be released through the static web plate of lower floor, and whole like this gas is thoroughly purified clean.
