Description

The filter of healthy wind purifying box

Technical field

The utility model relates to a kind of filter of healthy wind purifying box, belongs to healthy Wind Engineering system regions.

Background technology

Modern, after the harm that experienced by " smoke pollution " and " photochemical pollution ", suffer from and is polluting based on the third time of " room air pollution ".Show according to US Experts research, more serious than outdoor 2-5 times of the degree of room air pollution, even can reach 100 times under special circumstances.Environmental sanitation fabric study of Canada finds, the disease of the mankind 68% causes due to interior air pollution.Statistics display China has 110,000 people to die from room air pollution every year.The IAQ of nearly all Newly decorated rooms has problem, and some pollutants (as formaldehyde, benzene etc.) index exceedes national standard several times even tens times.As far back as 20 century 70 later stages, just there is the saying of " IAQ (IAQ) " in some western countries.1958, Europe took the lead in proposing the healthy wind concept of modern Interior, and releases the low noise pitch static pressure pressure fan being applicable to all kinds of place simultaneously.At that time for the consideration of economize energy, the air-tightness of building improved greatly, brought room ventilation rate not enough thus, caused room air pollution event again and again to occur.There is headache in some, dry cough, dry skin are itched, dizziness and nausea, notice are difficult to concentrate and to symptoms such as odor-sensitive, the situation that this is called as " sick building syndrome " has generation in a lot of country, and there is bitter lesson in each developed country in this respect.This makes people start further investigation and inquires into IAQ to the impact of human health, pollutant and source thereof and feasible solution route etc.

At present, people have started to adopt healthy Wind Engineering system to continue to provide pure and fresh, pure air for indoor.In healthy Wind Engineering system, healthy wind purifying box is equipped with in total-heat exchanger air intake side, while suck outdoor fresh air, foul atmosphere on one side in discharge chamber, impurity filters by the filter in healthy wind purifying box, thus the intrusion of pollen, dust etc. in prevention air, enable the fresh air kept fit in indoor.But there is following defect in the filter in existing healthy wind purifying box: usually adopt the plane filter material such as screen pack, cellucotton in filter, on the one hand, filter area is little, and filter efficiency is low, affects IAQ; On the other hand, because the dust containing capacity of plane filter material is little, and healthy Wind Engineering system cannot can reverse gas cleaning in real time as industrial dedusting system, and therefore cleaning cycle is short, and frequency of maintenance is high, maintenance and maintenance cost high, be not suitable for everyday home use.

Utility model content

According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of good filtration effect, can ensure IAQ and the filter of the healthy wind purifying box that frequency of maintenance is low, applicable everyday home uses.

The filter of healthy wind purifying box described in the utility model, comprises filter matrix, and filter matrix adopts honeycomb ceramic filter material, and filter matrix surface is coated with photo-catalyst film.

In the utility model, filter matrix adopts honeycomb ceramic filter material to have 3 D stereo filtration, on the one hand, its filter area opposite planar filtering material can become the growth of geometry multiple, such filtration velocity can significantly reduce, filter efficiency can significantly increase, thus effectively ensure IAQ, on the other hand, in honeycomb ceramic filter material, each semiclosed passage can receive certain dust, therefore its dust containing capacity increases substantially than traditional plane filter material, so just, the cleaning cycle of healthy wind purifying box significantly can be extended, reduce frequency of maintenance, more be convenient to healthy wind system and come into everyday home.When needing to obtain larger filter area, directly can increasing order number and the length of honeycomb ceramic filter material, without the need to increasing the fuselage height of healthy wind purifying box, namely under the prerequisite not increasing installation difficulty, significantly improving filter efficiency.

Filter matrix surface is coated with photo-catalyst film, like this under light irradiates, photo-catalyst film can produce the extremely strong free hydroxy of oxidability and active oxygen, there is very strong photoredox function, the various organic compound of oxidable decomposition and part inorganic matter, the cell membrane of bacterium and the protein of solidification virus can be destroyed, make antibiotic rate up to more than 90%, and the toxin that bacterium or fungi can be discharged is done to decompose and harmless treatment, simultaneously can decomposing organic pollutant, organic pollution is resolved into free of contamination water and carbon dioxide, thus there is extremely strong sterilization, deodorizing, mildew-resistant, anti-fouling and self-cleaning, air purification function.Wherein, photo-catalyst film adopts nano level metal oxide materials, preferred nano level titanium dioxide.

The beneficial effect that the utility model is compared with prior art had is:

The utility model reasonable in design, can improve filter efficiency by honeycomb ceramic filter material, effectively ensure IAQ, and can increase appearance dirt rate, prolongation cleaning cycle, minimizing frequency of maintenance, is applicable to everyday home and uses; By at filter matrix surface coating photo-catalyst film, the air entering indoor can be treated and carry out sterilization, purification.

In figure: 1, filter matrix; 2, photo-catalyst film.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

As shown in Figures 1 to 3, the filter of healthy wind purifying box described in the utility model comprises filter matrix 1, and filter matrix 1 adopts honeycomb ceramic filter material, and filter matrix 1 surface is coated with photo-catalyst film 2.In the present embodiment, photo-catalyst film 2 adopts nano level titanium dioxide.

In the utility model, filter matrix 1 adopts honeycomb ceramic filter material to have 3 D stereo filtration, on the one hand, its filter area opposite planar filtering material can become the growth of geometry multiple, such filtration velocity can significantly reduce, filter efficiency can significantly increase, thus effectively ensure IAQ, on the other hand, in honeycomb ceramic filter material, each semiclosed passage can receive certain dust, therefore its dust containing capacity increases substantially than traditional plane filter material, so just, the cleaning cycle of healthy wind purifying box significantly can be extended, reduce frequency of maintenance, more be convenient to healthy wind system and come into everyday home.When needing to obtain larger filter area, directly can increasing order number and the length of honeycomb ceramic filter material, without the need to increasing the fuselage height of healthy wind purifying box, namely under the prerequisite not increasing installation difficulty, significantly improving filter efficiency.

Filter matrix 1 surface is coated with photo-catalyst film 2, like this under light irradiates, photo-catalyst film 2 can produce the extremely strong free hydroxy of oxidability and active oxygen, there is very strong photoredox function, the various organic compound of oxidable decomposition and part inorganic matter, the cell membrane of bacterium and the protein of solidification virus can be destroyed, make antibiotic rate up to more than 90%, and the toxin that bacterium or fungi can be discharged is done to decompose and harmless treatment, simultaneously can decomposing organic pollutant, organic pollution is resolved into free of contamination water and carbon dioxide, thus there is extremely strong sterilization, deodorizing, mildew-resistant, anti-fouling and self-cleaning, air purification function.
