Description

Rural area, cities and towns domestic air purification device

One, technical field

The utility model relates to air cleaning facility, particularly for the indoor use of town-dweller-rural-family and public office space, especially solves the manufacturing field of the air cleaning unit of finishing back house and office occupancy use.

Two, background technology

In the last few years, along with industrialized process, no matter be that developed country or poverty-stricken area, dust pollution, industrial pollution, tail gas pollution of motor-driven vehicle, indoor decoration pollution, automobile internal contamination, refrigerator internal contamination and pet shelter pollution problems are increasingly serious, human life in modern society's air pollution serious threat.

The pollution day by day of modern Interior air, particularly serious to new residential houses personnel's influence.Behind the house decoraton finishing, the harmful and noxious substance (as: radioactive substances such as formaldehyde, organic matter, stink, peculiar smell, argon, benzene, carbon dioxide, radon) such as pungent dazzling that is come out on ornament materials and the furniture, its present situation is, new residential houses room air pollution, severe overweight, do not reach national IAQ standard-required (gb50325 and gb/t18883), and above-mentioned air-polluting present situation has constituted the very big threat to new residential houses personnel health.

Now everybody known air cleaning bag and clarifier product mainly are based on purification to automobile, refrigerator, pet shelter and small size house room air on the market, the purpose that reaches national air quality standard designs, and can not solve the indoor air that exceeds standard in large tracts of land house and office space becomes the IAQ standard through purification purpose.As: " anion activated carbon clean room " and " air purifier ", the two is a source of the gas with indoor dirty air all, and the former adopts cocoanut active charcoal to purify, and the latter adopts the electrostatic precipitator purified treatment to become fresh air.

Three, utility model content

The purpose of this utility model provides rural area, a kind of cities and towns domestic air purification device, to solve the problem that rural area, cities and towns large tracts of land house and the indoor air that exceeds standard in office space reach national air quality standard.This novel purpose is realized by following technical scheme: rural area, a kind of cities and towns domestic air purification device, comprise the cotton filter course of gel, just imitate the synthetic fibers screen pack, the catalytic activated carbon adsorption layer, the medium air filtration net, hepa high efficiency filter layer, nickel alloy photocatalyst purifying net, it is characterized in that, also has the ultraviolet sterilization purifier: be provided with a toroidal membrane in its sealing casing, respectively be provided with nut and the direct bolt of double end with filter-core shell bottom centre's point in the heart in the dividing plate, the higher authorities of bolt are fixed with an air purifying filter core of being made up of filter-core shell and a plurality of filtering layer, the arc top of filter-core shell has give vent to anger grid and venthole, the bottom of filter-core shell has built-in air admission hole, described catalytic activated carbon adsorption layer is arranged on the filter-core shell bottom, also be provided with the medium air filtration net on it successively, hepa high efficiency filter layer, nickel alloy photocatalyst purifying net, the left side on filter-core shell top and right side are provided with the ultraviolet sterilization layer, around reaching, the bottom of filter-core shell is provided with the cotton filter course of gel, just imitate the synthetic fibers screen pack, the bottom of toroidal membrane also is provided with gentle breeze fan, the bottom of gentle breeze fan is provided with base, the top of sealing casing is provided with the gas outlet, and the bottom base is provided with air-inlet grille.

In the above-mentioned design, seven layers of purifier of this novel employing one-level are with at the needs of eliminating pernicious gas such as in for waste gas that produces under the public environment and FASHIONHOME airborne formaldehyde, benzene series thing, ammonia and removing decoration odor.As pernicious gas such as airborne formaldehyde, benzene series thing, ammonia in the waste gas that produces down for public environment and FASHIONHOME and remove the decorations peculiar smell, basis is novel carries out the cotton filter course of gel to it, just imitate the synthetic fibers screen pack, the catalytic activated carbon adsorption layer, the medium air filtration net, after hepa high efficiency filter layer etc. purify, carry out the nickel alloy photocatalyst again and purify and ultraviolet sterilization layer purified treatment.

With prior art (existing air cleaning bag and clarifier handle the basis on) compare, the peculiar smell that this novel pin produces pernicious gas molecule such as airborne formaldehyde, benzene series thing, ammonia in the waste gas that produces down for public environment and the FASHIONHOME and decorations, increase the cotton filter course of one section gel, just imitated treatment steps such as synthetic fibers screen pack, catalytic activated carbon adsorption layer, medium air filtration net, hepa high efficiency filter layer, the purification of nickel alloy photocatalyst purifying net and the purification of ultraviolet sterilization layer.During this is novel, but all contaminations matter of the cotton filter course filtering of gel more than 20 microns, as hair, scurf, fiber, pollen, mould etc.; Just imitate the synthetic fibers screen pack and can effectively filter suspension, dust granules; The catalytic activated carbon adsorption layer can effectively be removed a large amount of fine particles, peculiar smell and pernicious gas, and decompose on limit absorption, limit, can not produce secondary pollution; The medium air filtration net can further filter airborne remaining dust granules and keep the institutional framework of active carbon; Hepa high efficiency filter layer to particle diameter be 0.3 micron with interior particle removal rate up to 99.97%; The photocatalyst purifying net have very strong redox, can decomposing formaldehyde, pernicious gas molecule, bacteriums such as benzene, ammonia, and kill measure such as airborne bacterium through the ultraviolet sterilization layer and purify air, make air cleaning pure and fresh.

This is novel to have following characteristics: 1, the effective all contaminations matter of filtering more than 20 microns, as hair, scurf, fiber, pollen, mould etc.; Can filter suspension, dust granules.2, can effectively filter suspension, dust granules, can remove a large amount of fine particles, peculiar smell and pernicious gas, decompose on limit absorption, limit, can not produce secondary pollution.3, can further filter airborne remaining dust granules, to particle diameter be 0.3 micron with interior particle removal rate up to 99.97%.4, have pernicious gas molecule, bacteriums such as very strong redox, decomposing formaldehyde, benzene, ammonia, kill airborne bacterium, thereby make air cleaning pure and fresh.5, the cleaned air passes quality is better than national IAQ standard-required (gb50325 and gb/t18883).

This novel economizer is suitable for, and be particularly suitable for office space, town and country and new home family and use, but each household is installed one.
