Abstract

The utility model relates to a purifying device. The utility model uses a resonant light source, photocatalytic surrounding net on the periphery of the resonant light source, an inner cavity wall of the device, and a spiral flow guide piece as a core; the resonant light source is arranged in the center of the purifying device; the spiral flow guide piece forms a spiral flow guide passage with the inner cavity wall of the device; a blast port of an axial-flow fan is correspondingly arranged on both sides of the lower part of the spiral flow guide passage; the other end of the purifying device has an air flow outlet; the photocatalytic surrounding net and the surface of the spiral flow guide passage have photocatalytic coatings; the purifying device and the lower part of the spiral flow guide passage have a water storage tank. When the utility model works, the air which needs to be purified enters the spiral flow guide passage in the purifying device under the pumping of the fan and can be sufficiently and thoroughly in contact with photocatalyst under an excited state for a long time and processed. The problem of air pollution is thoroughly solved. The utility model is an ideal substitute for environmental governance.

Description

A kind of air cleaner

Technical field

This utility model relates to environmental protection installation, specifically is a kind of photo-catalytic sterilization, the poison that goes out, taste removal, purifier.

Background technology

The living environment of mankind nowadays worsens day by day.The air pollution of room, office, working space is more and more heavier.Particularly after the house decoration, harmful gass such as the benzene that finishing material discharged, formaldehyde are very serious to people's murder by poisoning.And closed stable breeding breed places such as chicken farm, pig farm often stink to high heaven, and air pollution is even more serious.In addition, the outbreak of epidemic of bird flu, SARS in a word, purifies air, protects environment to become to be badly in need of the key subjects of solution.Though have multiple purifier invention to come out so far, result of use is all undesirable.The photocatalyst technology is a kind of high-tech green technology that development in recent years is got up, it relies on the irradiation of ultraviolet harmonic light to excite catalyst and water reaction to produce strong oxidizer HO free radical, effectively resolving harmful gas destroys the DNA tissue of virus, pathogenic bacteria in the air, makes it to lose replication capacity.And can destroy the cell wall of antibacterial, and Cytoplasm is run off to dead, reach efficient sterilizing, the effect of the poison that goes out, taste removal, can be widely used in the mankind and fowl dirty swine ever-changing environment.But because that the used ultraviolet light source of prior art etc. is selected for use is improper, particularly the cleaning equipment structural design is unreasonable, causes photocatalyst too short time of contact with the air that needs purified treatment, measure also very little, thereby inefficiency, treating capacity is little, effect is still undesirable.

Summary of the invention

This utility model is exactly a kind of novel photocatalyst purification plant that designs at the defective of the evolution device existence of existing employing photocatalyst technology.This purifier is to place the resonance light source at purifier center, the photocatalyst purse seine of resonance light source periphery and device internal chamber wall reach and the spiral flow deflector of its composition spiral stream guidance passage is a core, purifier one end housing body two sides are provided with axial flow blower, axial flow blower blast orifice correspondence is arranged at both sides, helical wind-guiding passage bottom, the purifier other end has air stream outlet, and photocatalyst purse seine and spiral stream guidance channel surface have the photocatalyst coating.The resonance light source be coated with in comprising rare earth luminous powder soda-lime-silica glass pipe ultraviolet fluorescent lamp 1 to several fluorescent tubes.The photocatalyst coating comprises employing 10-30nm grade titanium dioxide sodium rice material.There is aqua storage tank purifier and helical wind-guiding passage below.

This photo-catalytic sterilization, the poison that goes out, taste removal purifier have adopted ultraviolet resonance light source of emission band 180-380nm wavelength and 10-30nm grade titanium dioxide catalyst, produce electron hole pair, HO free radical with being adsorbed on the lip-deep water reaction of catalyst generation high oxidative capacity can reach sterilized taste removal effect.The air that need purify when purifying operation enters the spiral stream guidance passage in the purifier under the pumping of blower fan, but the long period (greater than more than 20 seconds) fully contacts with photocatalyst under the excited state, processed up hill and dale.Water in the tank of purifier bottom both can filter and need to handle airborne dust thing, the aerosolizable again reaction that is adsorbed on catalyst surface promotion HO free radical.

But this utility model device design and manufacture becomes series of products, be widely used in family room and various life, commerce, working space, fit up back and regular air cleaning operation, more can be used for closure stable breeding place fixed points such as hen house, pig farm, for a long time, thoroughly solve the air ambient pollution problem, the large tracts of land of the generation of minimizing disease and pathogenic bacteria, virus infects.Because it is with high content of technology, scientific and reasonable for structure, is the renewal product of ideal improvement environment.

Description of drawings

Fig. 1 is this utility model purifier structural representation.

Among the figure, 1 aqua storage tank, 2 spiral flow deflectors, 3 spiral stream guidance passages, 4 photocatalyst purse seines, 5 axial flow blowers, 6 resonance light sources, 7 purifier housings, 8 exhaust outlets, 9 purifier loam cakes, 10 photocatalyst coatings, 11 internal chamber walls.

The specific embodiment

Shown in Figure 1, be a kind of embodiment of this utility model.This photo-catalytic sterilization, the poison that goes out, taste removal purifier are by the resonance light source 6 that places the purifier center, the photocatalyst purse seine 4 of resonance light source 6 peripheries and device internal chamber wall 11 reach and the spiral flow deflector 2 of its composition spiral stream guidance passage 3 is the device core, purifier one end housing body 7 two sides are provided with axial flow blower 5, the blast orifice correspondence of axial flow blower 5 is arranged at both sides, helical wind-guiding passage bottom, the purifier other end exhaust outlet 8 that purifies air.There is photocatalyst coating 10 on photocatalyst purse seine 4 and spiral stream guidance passage 3 surfaces.In comprising, resonance light source 6 is coated with the soda-lime-silica glass pipe B band ultraviolet fluorescent lamp of rare earth luminous powder.Catalyst coating can be a 10-30nm sodium titanium rice material.There is aqua storage tank 10 housing 7 bottoms, helical wind-guiding passage below.This device can be used as movably on-the-spot air-treatment purifier, makes purified treatment for the sealing places such as room behind the finishing, also can be fixedly installed in sealing places such as chicken house, pigsty and regularly carry out regular surrounding air improvement.
