The structure is capable of efficiently removing the harmful gases such as formaldehyde; the nano composite catalyst is mixed with the active carbon according to a best ratio, so that the double effects of physical adsorption and chemical reaction are implemented.
Description
Technical field
The invention belongs to environmental friendly material field, for the filter course of air purifier, the filter course package assembly that the catalyst being specifically related to a kind of efficient removing pernicious gas mixes with adsorbent.
Background technology
Air purifier had become one of main hot product of household electrical appliances market in recent years.The appearance of the series of problems of environmental pollution, new type influenza, indoor pollution, air quality drives the development of global air cleaning facility.Air purifier has become global household electrical appliances market and has received much concern and the hot product pursued.
Domestic market has multiple air purifier sell, their appearance and modeling is different, and watt level differs, for family or public place.The critical component affecting air filtration effect is the filter course in machine, on market, the filtering layer of most air clarifier is made up of HEPA screen pack and active carbon layer, adopt this screen pack, big dust particle can be filtered, pernicious gas in air such as formaldehyde etc. also can be adsorbed by active carbon on a small quantity, but the pernicious gas of charcoal absorption can be passed in time and be parsed by secondary, comes back in air, causes secondary pollution.Therefore in essence, pernicious gas is not removed at all.
Summary of the invention
The object of this invention is to provide the filter course package assembly that a kind of catalyst removing pernicious gas mixes with adsorbent, adopt this structure efficiently can remove the pernicious gases such as formaldehyde, and mixed with the optimal proportion of active carbon by nano-composite catalyst, play the double effects of physical absorption and chemical reaction.
Object of the present invention is achieved through the following technical solutions:
The filter course package assembly that the catalyst removing pernicious gas mixes with adsorbent, is characterized in that: this structure comprises nano-composite catalyst and active carbon, and described nano-composite catalyst and active carbon carry out Hybrid assembling in the ratio of 9:1 ~ 1:9; ; This nano-composite catalyst is graininess, and the surface of particle has adsorption hole; Described nano-composite catalyst is the solid particle that nano platinum particle maybe can absorb the aminated compounds of formaldehyde, urea derivative reproducibility sulfur-containing compound, oxide; Graininess is that nanoscale solids particle is formed by grain size specification.
In the present invention, nano-composite catalyst can be circle beans graininess.Catalytic nanoparticles forms by reducing the transition metal of organic matter and oxygen oxidizer reaction activity or noble metal and salt thereof; Solid particle and the reagentia of formaldehyde organic matter.The compatibility of platinum nano catalyst and other reactive compounds serves concerted catalysis effect again further, accelerates the decomposition of the volatile organics such as formaldehyde in air.
Active carbon is a kind of porous material, and it has highly developed hole structure, and specific area is large, fully can contact, thus impart absorption property specific to active carbon, by noxious substance in hole with gas or impurity.But can resolve by secondary after charcoal absorption is saturated, final absorption reaches dynamic equilibrium with parsing, makes active carbon lose its effect.This balance has been broken in adding of composite catalyst.After powering, active carbon is to be adsorbed as master, and resolve to auxiliary, composite catalyst then constantly cartalytic decomposition effect occurs, and the harmful substances such as the formaldehyde of absorption are resolved into CO
2and H
2o.The harmful substance flowed through in the air of composite filter is constantly decomposed on the one hand, and undecomposed nuisance is then tightly held by activated carbon, and like this, after air circulates repeatedly, harmful substance is finally thoroughly removed, and maintains the with fresh air of indoor.After shutdown, active carbon, then to resolve to master, remains in the pernicious gas in active carbon, parses rear continuation by composite catalyst catalytic decomposition.By catalyst and active carbon with the use of, make air purifier after shutdown, also can play the effect of resolving harmful gas.
Nano-composite catalyst mixes with active carbon by the present invention by a certain percentage, when starting shooting, physical absorption and chemical catalysis decomposition reaction occurs, air is purified, after shutdown, also has the ability that certain subsequent catalyst decomposes, fundamentally carry out decomposing harmful substances, remove pernicious gas.

Detailed description of the invention
The filter course package assembly that the catalyst removing pernicious gas mixes with adsorbent, this structure comprises nano-composite catalyst and active carbon, and nano-composite catalyst and active carbon carry out Hybrid assembling in the ratio of 9:1 ~ 1:9.Fig. 1 is the appearance schematic diagram of nano-composite catalyst in the present invention, and in figure, 1 be nano-composite catalyst, 2 is adsorption holes.This nano-composite catalyst 1 is circle beans shape particle, and the surface of circle beans shape particle has adsorption hole 2.Nano-composite catalyst is the solid particle that nano platinum particle maybe can absorb the aminated compounds of formaldehyde, urea derivative reproducibility sulfur-containing compound, oxide; Circle beans shape particle is that nanoscale solids particle is formed by grain size specification.
In the present invention, catalytic nanoparticles forms by reducing the transition metal of organic matter and oxygen oxidizer reaction activity or noble metal and salt thereof; The reagentia of the organic matter such as solid particle and formaldehyde.The compatibility of platinum nano catalyst and other reactive compounds serves concerted catalysis effect again further, accelerates the decomposition of the volatile organics such as formaldehyde in air.The catalysis material genus polyporus material of circle bean or pea shape, can ensure that active catalyst component disperses fully in hole.And spherical particle gap is beneficial to air circulation, reduce air flow resistance, reduce set noise.
The catalyst size of preparation is nanoscale, and specific area is large, and catalytic activity is high, effectively the pernicious gases such as formaldehyde, volatile organic matter (VOC) can be resolved into carbon dioxide (CO
2) and water (H
2o).
When starting shooting, physical absorption and chemical catalysis decomposition reaction occurring, purifies air, after shutdown, the ability also having certain subsequent catalyst to decompose, carrys out decomposing harmful substances.
