Description

The fresh wind tube road purifies, sterilization machine

Technical field

The utility model relates to a kind of air cleaning unit, especially relates to the purification of a kind of fresh wind tube road, sterilization machine.

Background technology

In the modern life, can produce a large amount of pollutants, comprise: the pollutant that the burning of tobacco, all kinds of solvents, paint, computer and printer, wallpaper, carpet etc. produce indoor; Coal combustion produces pollutants such as sulfur dioxide, carbon monoxide, nitrogen oxide.Also have pellets such as dust, bacterium, scurf, hair in the room air.

Modern architecture is used iron and steel and various high performance plastic products in a large number; Mostly contain organic compounds such as formaldehyde, benzene class, chloroform in these materials; The high speed development of building materials industry and the rise of fitting-up craze, the pollution that is caused by ornament materials has become the main source of indoor pollution.Under the support of the requirement of building energy conservation and modern science and technology, the especially generally use of air-conditioning, the seal of interior architecture is become better and better, and the exchange of room air and outdoor air is fewer and feweri, has caused the further deterioration of IAQ.

Indoor air cleaner be realize air cleaning the most directly, instrument easily, along with the continuous variation of room air pollution character and the increasing of pollution level, the indoor air cleaner technology has also obtained developing apace.The air purifier product has at present: mechanical filter formula clarifier, mechanical filter adsorption cleaning device, electrostatic purifier, anion purifier, ultraviolet light air purifier etc.

Mechanical filter formula clarifier is a kind of small air filter, and air pressurizes through blower fan, through filtering material, thereby purify particulate pollutant, but this form can only be removed a certain size particulate pollutant, and overall clean-up effect is not good.

Mechanical filter adsorption cleaning device; Adopt different purification mechanisms to take out particulate pollutant and gaseous contaminant respectively; This clarifier combines normal air filtering technique and charcoal absorption technology, has improved purifying property generally, but there is the absorption saturation state in active carbon; Cumbersome, thereby be not used widely.

Electrostatic purifier is a kind of electrostatic air filter, and is better to bigger particulate pollutant effect, still can produce secondary pollutions such as ozone, just progressively eliminated.

Anion purifier, anion purifier are a kind of clarifiers that is widely used at present, produce anion through highfield and combine to form " heavy ion " with particulate pollutant; Sedimentation or be adsorbed on body surface; And the ability kill bacteria, clean-up effect is good, still; This air purifier can produce ozone equally, causes secondary pollution.

The ultraviolet light air purifier is to penetrate the cells of microorganisms film through ultraviolet irradiation; Destroy the dna structure of germ, bacterium, parasite and other pathogens; Damage its nucleic acid molecules key, make the dead at once or irreproducible offspring of bacterium, thereby reach the effect of sterilization; Its disinfection way environmental protection, sterilizing function is reliable.But because the flowability of room air is poor, it is unsatisfactory directly disinfection by ultraviolet light to be applied to the purification effects of room air.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, the purification of a kind of fresh wind tube road, sterilization machine are provided, so that ultraviolet disinfection way can be advantageously applied to the purification of room air, guaranteeing the clean-up effect of room air.

The utility model technical solution problem adopts following technical scheme:

The utility model fresh wind tube road purifies, the design feature of sterilization machine is: in the ventilation shaft of central air-conditioning, air purifier is set, said air purifier is provided with: be in the filter element on the cross section of ventilation shaft; The ultraviolet sterilization unit that is positioned at the central authorities of ventilation shaft, constitutes by ultraviolet lamp tube; And be arranged on the ultraviolet lamp tube control module in the air purifier casing.

The utility model fresh wind tube road purifies, the design feature of sterilization machine also is:

Said filter element is to form interlayer with two metal filter screens, is absorption type dust removal by filtration plate in the interlayer; The surface of said absorption type dust removal by filtration plate is provided with the photochemical catalyst antimicrobial coating.

Said ultraviolet lamp tube control module is set to:

One ultraviolet lamp tube duty detecting unit, the testing result of indicating said ultraviolet lamp tube duty with the indicator lamp and the buzzer of supporting setting;

One ultraviolet lamp tube operation irregularity reset unit is realized the zero initialization of said ultraviolet lamp tube working time with the reset key of supporting setting.

Compared with present technology, the utility model beneficial effect is embodied in:

1, the utility model is to carry out circulating of room air by central air-conditioning fan air inducing; Air is flowed through in ventilation shaft and is sent into indoorly after filter element and ultraviolet sterilization unit in the air purifier is purified, and reaches the effect of good indoor air purification;

2, the utility model combines with ultraviolet sterilization and photochemical catalyst, and sterilization effect is good;
