Description

A kind of air-conditioning filter net for removing formaldehyde

Technical field

This utility model relates to air-conditioning filter net, specifically, relates to a kind of air-conditioning filter net for removing formaldehyde.

Background technology

In recent years, the pollution of indoor environment such as building and automobile becomes increasingly conspicuous, and arouses extensive attention at home and abroad. Formaldehyde is one main in indoor pollutant, is regarded as carcinogen by WHO, has very high carcinogenecity. Formaldehyde in newly-decorated indoor floor, furniture can sustained release 3��5 years even longer time. Can not windowing for a long time when or air conditioning for automobiles internal recycle relatively low particularly in winter makes outdoor temperature ventilation, cause that the formaldehyde evaporated in confined space gathers, concentration improves rapidly, is in this kind of environment for a long time and will have a strong impact on the health of people. In prior art, mainly through using air purifier, the means such as ventilation of windowing to solve the air in closed space pollution problem owing to finishing or other reasons cause. Disclose a kind of except formaldehyde air purifier in Chinese patent CN104437007A, utilize formaldehyde absorbent to be removed formaldehyde. Chinese patent CN204285647U discloses a kind of air purifier utilizing activated carbon adsorption to remove formaldehyde. Although the depurator that above-mentioned patent provides can purifying formaldehyde to a certain extent, but all can need equipment and take the interior space by volume, and needing to be additionally provided energy support.

Purifying formaldehyde module is supported the use with indoor ventilator units such as air-conditionings, is a kind of method of new type purification room air, had both added the function of air-conditioning, save space and the energy than being used alone air purifier again. Patent CN202212087U disclose a kind of be arranged on air-conditioning except formaldehyde, ceramic mould formaldehyde absorbing block is positioned over fixed frame and is connected with air conditioner filter screen, to reach the purpose of the harmful gass such as in ventilation process removal formaldehyde. But the ventilation of air-conditioning can be produced impact by the way of this extra placement Attraction block, and adopts absorption method except formaldehyde, and after absorption is saturated, easily desorption causes secondary pollution. Catalytic oxidation is a kind of method of high-efficient purification formaldehyde, and formaldehyde can be converted into continuously harmless CO under relatively mild condition₂And H₂O, be solve Formaldehyde Pollution of Indoor Air another effective means (Ind.Eng.Chem.Res.,2015,54:8900-8907;CatalysisToday,2015,258:56-63)��

Utility model content

The purpose of this utility model is in that to overcome the deficiencies in the prior art, a kind of air-conditioning filter net removing formaldehyde for being arranged on air-conditioning is provided, this filter screen structure is simple, be prone to support the use with air-conditioning, can pass through while operation of air conditioner the effect of the harmful gass such as catalyzed conversion process removal formaldehyde in air, and does not result in secondary pollution.

To achieve these goals, this utility model adopts the following technical scheme that

A kind of air-conditioning filter net for removing formaldehyde, purification wire netting two parts that described air-conditioning filter net is coated with porous metal oxide layer and metal active constituent Pt, Ru, Rh, Pd, Au or Ag or its oxide by fixed frame and surface form, described fixed frame is two-layer grid frame structure, forming interlayer between two-layer grid frame, described purification wire netting is arranged in mezzanine space.

Compared with prior art, this utility model has the advantages that air-conditioning filter net of the present utility model, mechanical performance is strong, good heat conductivity, have the macro-size suitable with common air-conditioning drainage screen and pattern, normal operation and the air-conditioning etc. that do not affect air-conditioning with air-conditioning etc. when supporting the use support the use, utilize the ventilation circulation system of air-conditioning, both added the air-cleaning function of air-conditioning, provided cost savings and the energy than being used alone air purifier again.

The fixed frame of air-conditioning filter net of the present utility model and purifying net are assembled integrally the integrally-built air-conditioning filter net of formula, it is simple to dismounting, cleaning and replacing.

Air-conditioning filter net of the present utility model, wire netting surface in situ generates and is loaded with metal active constituent Pt, Ru, Rh, Pd, Au or Ag or its oxide on porous metal oxide layer and porous metal oxide layer, can be water and carbon dioxide by formaldehyde pollutants catalytic oxidation when operation of air conditioner.

Detailed description of the invention

As Figure 1-3, one is used for removing formaldehyde air-conditioning filter net, described air-conditioning filter net is made up of the fixed frame 1 being connected with air-conditioning and purification wire netting 2 two parts, described fixed frame is two-layer grid frame structure, forming interlayer between two-layer grid frame, described purifying net 2 is arranged in mezzanine space; Described purification wire netting 2 includes wire netting, and wire netting surface in situ generates porous metal oxide layer, and porous metal oxide layer is loaded with metal active constituent Pt, Ru, Rh, Pd, Au or Ag or its oxide.

Above-mentioned fixed frame 1, it is possible to be made up of a kind of metal in aluminum, titanium or rustless steel,

Its size is identical with the air conditioner filter screen of required coupling. Two-layer grid frame can be docking together, and docking mode can adopt known various connected modes, such as chimeric, means of spot welds, threaded etc.

The preparation method of above-mentioned purification wire netting is: wire netting is carried out oxidation processes, as high temperature oxygen-containing atmosphere is calcined and electrochemical anodic oxidation process etc., at wire surface in-situ preparation porous metal oxide layer; Then utilize the saline solution of one or more in infusion process carried metal active component Pt, Ru, Rh, Pd, Au or Ag, then pass through dry, calcining and reduction is purified net.

Above-mentioned air-conditioning filter net uses step as follows: similar with installing air-conditioning filter net, and product of the present invention is replaced the drainage screen that air-conditioning carries. If air-purifying net need to be changed, then by two-layer grid frame separately, separating method determines according to its connected mode, then can freely change the purifying net of same specification or install the purifying net of different detergent power additional after separately.

Claims

1. the air-conditioning filter net being used for removing formaldehyde, it is characterized in that: purification wire netting two parts that described air-conditioning filter net is coated with porous metal oxide layer and metal active constituent Pt, Ru, Rh, Pd, Au or Ag or its oxide by fixed frame and surface form, described fixed frame is two-layer grid frame structure, forming interlayer between two-layer grid frame, described purification wire netting is arranged in mezzanine space.
