Description

Novel photocatalysis air purifier

Affiliated technical field:

The utility model relates to a kind of air purifier, and particularly relating to a kind of is the indoor air cleaner of main purification means with photocatalysis.

Background technology:

Photocatalysis has at present obtained increasing attention as the air cleaning means.The performance of light catalytic purifying effect requires ultraviolet light, catalyst and meets the pollutant that needs to remove the time.Thereby the high efficiency of catalyst, effective cloth photo structure, sufficiently long reaction bed and pollutant are four big key factors of decision purification efficiency in the sufficiently long time of staying of reaction interval.But at present light catalytic purifying device, the catalyst in market and the patent mostly is simple modifying titanium dioxide, to the pollutant adsorption capacity a little less than; Used catalyst mostly is network structure, and light-receiving area is less; Used reaction bed mostly is straight-through structure, and reaction path is shorter, thereby has limited the efficient of light catalytic purifying reaction greatly.The small amount of ozone that produces when simultaneously, uviol lamp is worked or the leakage of ultraviolet light also can cause secondary pollution.Thereby the efficient and the security of existing photocatalysis air purifying device all have much room for improvement.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes existing light catalytic purifying device, provides a kind of purifying property and security higher room light catalytic cleaner.

The utility model clarifier is mainly by blower fan, uviol lamp, constitutes the gas channel that increases and forms as the combined parallel dividing plate and the ozone decomposition catalyst bed of catalyst carrier.It has increased the distance of air communication time that crosses clarifier institute warp by diaphragm structure; Tabular assembly center by tubular uviol lamp being set in the supported catalyst that is parallel to each other also adds at the clarifier inwall and to be coated with reflection layer to have obtained best light efficiency; Increased the time of staying of pollutant on catalyst by the titanium deoxide catalyst of using the sorbing material modification; By using ozone decomposition catalyst to eliminate issuable ozone secondary pollution, realized the design of efficient, a safe room light catalytic cleaner.

In order to strengthen the purification efficiency of clarifier, the utility model has also installed ozone additional respectively in airflow inlet and exit living device and anion generator utilizes cooperative effect between each function to increase substantially the function of clarifier.

During operation, the gas channel that makes airflow passes have the dividing plate of catalyst to constitute by air blast or exhausting by appendix, the ventilation breach on the dividing plate or the arranged in dislocation in duct force air-flow to flow through with flexuose approach, increased the chance that contacts with catalyst greatly, the tubular uviol lamp that is installed on parallel-plate assembly center can make ultraviolet lighting be mapped to each part of the catalyst layer of coated on the parallel-plate.Be added with for example contour sorptive material of activated carbon in the used catalyst coat, make all contaminations molecule to be removed on catalyst, adsorb, concentrate, thereby improved reaction efficiency.The ozone of supervening during uviol lamp work, purification function there is certain strengthening effect, but it enters the interior space, then can cause secondary pollution, the utility model adds in the rear end uses ozone decomposition catalyst, can effectively the ozone that exists in the tail gas be decomposed, efficiently solve this long-standing problem of light catalytic purifying device.And, also can add the drop ozone generator in clarifier air inlet section, so can effectively improve the purification function of light catalytic purifying device.

In order to prevent to forget that shutdown with energy savings and prolong the clarifier life-span, is provided with time switch in the clarifier, make clarifier through (1-10 hour) after setting working time shutdown automatically.

Compare with existing photocatalysis air purifying device, the utility model has been created higher light catalytic purifying reaction probability by the particular design of reactor and catalyst.And because of adding with the ozone purification function and taking to be provided with the ozone decomposition catalyst section and import and export the method that the grid place adds photomask, the efficient and the security that have improved clarifier at air-flow.

Description of drawings:

Accompanying drawing is the structural representation of one of the utility model embodiment, wherein:

1. casing; 2. air inlet; 3. ozone generator;

4. coated has the dividing plate of catalyst; 5. uviol lamp; 6. quartz socket tube;

7. ozone decomposition catalyst; 8. blower fan; 9. anion generator;

10. gas permeability shadow shield.

The specific embodiment:

Now the utility model is described in further detail in conjunction with legend.

Room air enters the zigzag air channel that is made of multi-disc parallel baffle (4) under the drive of air-introduced machine (8), the dividing plate center is equipped with uviol lamp (5), and the baffle surface coated has the modified titanium dioxide photocatalyst with the activated carbon coexistence.The catalyst coat of high surface area is subjected to the abundant irradiation of ultraviolet light.The pollutant that exists in the air-flow be subjected to recombination catalyst layer absorption, concentrate and and then light reaction takes place and eliminated.The small amount of ozone and the cooperative effect between photo-catalysis function that produce when ozone that ozone generator produced that adds before the clarifier and uviol lamp work cause higher purification consequence.Residual ozone takes place to decompose fully at the ozone decomposition catalyst bed that is arranged at the clarifier back segment, imports and exports on the grid at air-flow and is provided with the foam porous black light-blocking film of the gas permeability that is made into by carbon fiber, prevents that ultraviolet light from spilling outside the clarifier.Owing on the clarifier exit flow passage anion generator is housed again, thereby the utility model clarifier can also produce the fresh air of band high-concentration anion except the characteristics that higher one way purifying rate and non-secondary pollution can be arranged.By continuous circulation, just can reach the purpose that efficiently purifies the air of a room.

Present embodiment is as a purifier unit, can use separately, but also serial or parallel connection constitutes bigger purification device, under one situation of back, can unify only to use a bigger blower fan, and the clarifier import or export end place that is installed in after the combination gets final product.
