Description

Compound air purification assembly

Technical field

This utility model belongs to air cleaning facility field, is specifically related to a kind of compound air purification assembly.

Background technology

Air pollutants include particulate pollutant and chemical pollutant.Wherein particulate pollutant can be divided into radius The fume that bigger macroscopic particulate pollutant (such as dust, flying dust) and naked eyes difficulty are distinguished, micro- Grain (particle matter) includes the various small-sized or miniature solid matter (list existed with graininess Body, compound, mixture etc.), liquid substance, and antibacterial, virus, the live body of small-sized biological or The entirety of corpse or local etc..Chemical molecular that chemical pollutant refers to exist in a gaseous form, atom, Monomer or mixture, common are sulfur dioxide, hydrogen sulfide, nitrogen oxides, benzene, toluene, petrol and diesel oil Escaping gas, formaldehyde gas, xylol (px) gas etc..

Air cleaning facility, refers to filter or kill air pollutants, be effectively improved air cleanliness Product, generally comprise particulate pollutant filter assemblies and chemical pollutant purification assembly.Particulate pollutant Filter assemblies removes the material of granule/particle matter in air-flow, group generally by physical methods of filtration The filter of part or finished product, such as commercialization.Chemical pollutant purification assembly typically contains adsorbing medium, Adsorbing medium can pass through molecule/interatomic Van der Waals force and attract, or the effect of the chemical bond between material Chemical pollutant capture is collected in inside adsorbing medium by power etc..

The air cleaning facility of existing market main flow is as shown in Figure 1: in equipment box 1 successively at the beginning of configuration Effect filter 2 (removal bulky grain), preposition medium effeciency filter 3 (removal microgranule), blower fan 4, The adsorbent bed 5 (removal chemical pollutant) of grain activated carbon/aluminium oxide, rearmounted medium effeciency filter 6 (is removed The microgranule of residual in microgranule that the former distributes and air-flow a) etc. assembly.Air-flow a is overall after equipment Purifying, system downstream is sent in air-out.Wherein the concrete structure of adsorbent bed 5 is, uses about 300mm The hollow hollow out web plate of spacing, inside fills up column, graininess or the modification of the shape such as spherical or non-modified Activated carbon, aluminium oxide or other granule, or the mixing material of above material.This device structure is loose, Have bulky, energy consumption is high, high in cost of production defect, change inconvenient, safeguard loaded down with trivial details, additionally equipment Always there is space in casing 1, and adsorbent bed 5 can distribute the toxic dust being adsorbed with pollutant, poisonous powder Dirt easily distributes leakage from the space of equipment box 1, there is certain potential safety hazard.

Fig. 2 show the air cleaning facility containing honeycomb adsorbing material of a kind of improvement, uses honeycomb to inhale Replace for attached section 7 adsorbent bed 5 to remove chemical pollutant, eliminate preposition medium effeciency filter 3 simultaneously.Wherein Honeycomb adsorption section 7 concrete structure is: use the metal of about 300mm or plastic casing, embedded necessarily The honeycomb adsorbing material (such as cellular activated carbon) of thickness, and be filled with buffering, admittedly by flexible material Determine and seal, assembling deflector before and after honeycomb adsorbing material, pass the gas through honeycomb adsorbing material with this Except chemical pollutant.The volume of this equipment is to a certain degree obtaining optimization reduction, can reduce part energy consumption, But System Back-end need nonetheless remain for being separately provided the particulate filtration unit such as rearmounted medium effeciency filter, whole equipment Volume is the biggest, and space availability ratio is the highest；Additionally the honeycomb adsorption section 7 of this equipment can reduce But cannot be avoided the generation of toxic dust and distribute, a small amount of toxic dust distributed still may pass through Rearmounted medium effeciency filter is gone out from the air gap leakage of equipment box 1 before filtering.

Utility model content

Therefore, this utility model is relatively big for air cleaning facility volume of the prior art, and energy consumption is higher, Change maintenance cost higher, easily reveal the technical problem of toxic dust, it is therefore intended that provide one to have That effect reduces the volume of air cleaning facility and energy consumption and can avoid revealing the composite air of toxic dust Purification assembly.

Compound air purification assembly of the present utility model includes:

At least one of which is for the cellular chemical catalysis module of adsorbing chemical contaminants；

At least one of which is located at the rearmounted particle filter layer of described chemical catalysis module rear end；And

One by described chemical catalysis module and the housing of the sealed envelope of particle filter layer, described housing two ends Have airflow inlet and air stream outlet.

Described combined filtration assembly can be adsorbed or catalytic chemistry pollutant by described chemical catalysis module, with Time may filter that interception fume by described particle filter layer.Described chemical catalysis module is micro-with described Grain filter course close-packed arrays is also wrapped up by described housing seal, compact conformation, is provided with described combined filtration The air cleaning facility of assembly not only can omit preposition medium effeciency filter, and without additionally mounted rearmounted Medium effeciency filter, equipment volume can be greatly reduced, thus can effectively reduce energy consumption；It addition, described chemistry Catalytic module is difficult to distribute toxic dust, adds that described chemical catalysis module rear end is close to described rearmounted microgranule Filter is also wrapped up by described housing seal, and described housing can block toxic dust and distribute from side, even if Described chemical catalysis module gives out a small amount of toxic dust, and toxic dust also can flow to rear end by after described Put particle filter layer to filter, thus avoid toxic dust to be leaked to outside described combined filtration assembly, and then Toxic dust is avoided to be leaked to outside air cleaning facility.

In a preferred embodiment of the present utility model, it also includes being located at described chemical catalysis module front end also Deflector.Described deflector can make air-flow uniformly flow through from each position of described chemical catalysis module, Improve the clean-up effect of described chemical catalysis module.

In a preferred embodiment of the present utility model, it also includes that at least one of which is located at described deflector front end Preposition particle filter layer.

Described rearmounted particle filter layer can be set to flat, discounting formula, convolution or other are any feasible Shape.Described preposition particle filter layer also can be set to flat, discounting formula or convolution.

The profile of described combined filtration assembly can adjust according to the architectural feature of actual air cleaning equipment, i.e. The cross section of described chemical catalysis module, described particle filter layer, described deflector and described housing can set For square, circular or other row shapes.
