Description

Interior environmental air pollution purifier

Technical field

This utility model relates to a kind of interior environmental air pollution purifier, belongs to the air cleaning technical field.

Background technology

The interior environmental air pollution purifier of domestic production at present and use mainly comprises two types, and a kind of is air purifier, and another kind is the detoxifcation clearing machine of filtered air of both having sterilized.Wherein the Yadu air purifier is mainly handled room air by the absorption of coarse filtration net, HEPA high efficiency filter and catalytic activated carbon absorption decomposition, its major advantage is that the catalytic activated carbon that it adopts can decompose while adsorbing, can not produce secondary pollution, increase the service life greatly, and adopted negative oxygen ion generating device; Shortcoming is to fail the disinfection technology and the purification techniques of air are combined as a whole, and has paid attention to purification, and sterilization and antibacterial effect are not obvious, and the replacing of filtrate bothers.In house ornamentation difficult to understand detoxifcation clearing machine adopt preposition anti-equal Air Filter, efficient catalyst sodium rice to filter quadruples such as antibiotic net, active carbon filter net, grain active carbon drainage screen to filter and reach the purpose that purifies and improve ambient air quality; its advantage is that filter area is big, resistance is little, filter screen is in light weight, and volume is little.Can effectively remove formaldehyde and stupid, also possess the function of sterilization, filtered air; Shortcoming is that it has paid attention to sterilization and antibiotic, and clean-up effect is not obvious, and parameter such as actual air volume has gap with designing.Because it adopts ozone to carry out disinfection, and ozone concentration reaches more than the 0.1PM, will play the effect that sterilization removes in addition.But concentration will be sent strong stench after reaching 0.15PM, and its environment for use can not surpass 30 degrees centigrade, otherwise carcinogenic easily.How finding a kind ofly effectively the disinfection technology of air with purification techniques is that combine and air cleaner that can realize comprehensive purification, is the problem of being concerned about in the industry.

The utility model content

The purpose of this utility model is in order to overcome the deficiency in prior art and the design, provide a kind of and effectively the disinfection technology of air and purification techniques are combined, and have the air cleaner that primary efficient filter screen, high efficiency filter, active carbon filter net are used photocatalysis technology simultaneously and can be realized comprehensive purification.Make it have pollutant and disinfection function in perfect filtration, absorption, the decomposition air.

Interior environmental air pollution purifier, it comprises that cylindrical housings, primary efficient filter screen, HEPA high efficiency particulate air, active carbon filter net, light that lid is arranged up and down touch and adheres to filter screen, UV uviol lamp, centrifugal blower, it is characterized in that:

A) its loam cake of cylindrical housings and sidewall have slip diffuser, and the upper and lower cover inboard of cylindrical housings has the grooved circuit;

B) ecto-entad is aligned in sequence with primary efficient filter screen, HEPA high efficiency particulate air, active carbon filter net and light and touches and adhere to filter screen in the cylindrical housings, and every kind of net is inserted in respectively in separately the grooved circuit, is connected with the UV uviol lamp in the lower cover center;

C) center of its loam cake is connected with centrifugal blower by flange in the cylindrical housings.

Described cylindrical housings is connected by internal and external threads with lower cover.

This device adopts the circular air draught of 360 degree, and middle upwards air-out reaches comprehensive air cleaning, does not stay dead angle and good looking appearance, can be placed on indoor any position, and the slip diffuser of around the housing and top distribution is used for air draught and air-out; The purpose of dress uviol lamp is on the one hand because of ultraviolet bactericidal action, and the luminous photocatalyst that makes of uviol lamp is had an effect on the other hand, and the light that sends impels photocatalyst to remove antibacterial and virus by strong oxidation, thus the propagation of control disease; Installing uviol lamp additional in the middle of device is to help photocatalysis on the one hand, be because uviol lamp is installed in air outlet or is installed in air inlet on the other hand, two kinds of possibilities that leakage is all arranged, simultaneously need the regular hour to finish during the disinfection of uviol lamp, the fast sterilization effect of wind speed is poor, so this device is installed in the centre to uviol lamp; Lower cover adopts with housing and is threaded, and the lower cover of can outwarding winding easily carries out the replacing of filtrate and uviol lamp and cleans.

This utility model not only have dedusting, sterilization, taste removal, etc. multiple function, but also have the advantages that volume is little, low in energy consumption, noise is low.Can be widely used in working environment, eliminate foreign flavor indoors, flue dust, kill the respiratory infectious disease bacterium; Be applied to domestic environment, can remove rotten musty in the bed body smell, peculiar smell in toilet, kitchen in bedroom in the family etc.; Be applied to fit up environment, can efficiently remove since make paint, the toxic and volatile thing of a large amount of formaldehyde that composite plate, water-repellent paint etc. produce, benzene and so on; Be applied to hospital environment, can remove the anaphylactogen of anaphylactic disease in the air etc.; Be applied to traffic environment, can remove cigarette, mist, bed body smell, ornament materials volatile matter etc. in car, ship, the aircraft; In addition, this device also can be applicable to the place of business.
