Description

A kind of air cleaning unit of catalytic decomposition formaldehyde
Technical field
The present invention relates to a kind of air cleaning unit of catalytic decomposition formaldehyde, belong to air purification field.
Background technology
Along with growth in the living standard, people are more and more higher for healthy requirement, and room air pollution is that people extremely are concerned about and problem demanding prompt solution.The kind of indoor pollutant can reach thousands of kinds, such as the kitchen oil flue dust, and floating various ciliums in air, the formaldehyde that ornament materials discharges, ammonia etc., these all allow the healthy of people make the matter worse.In numerous pollutants, formaldehyde is mathematical to the adverse effect of people's health.It also has the hardness of strengthening sheet material and insect protected, corrosion-resistant function except having stronger bond properties, in plastics, heat-barrier material and the Wood-based Panel Furniture therefore used at ceiling at home, floor, wall veneer, generally all contains formaldehyde.Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, women's paramenia, pregnancy syndrome, causes that neonate's physique reduces, chromosome abnormality, even causes nasopharyngeal carcinoma.In addition, dry air, especially winter room heater, air-conditioning effect, the air drying, also have a strong impact on our health, keeps certain air humidity, to healthy be also necessary.
Current, air purifying process has had quickish development, and the method for removing formaldehyde also has a variety of.Wherein, the active carbon absorption process is simple, but easily reaches capacity, and the active carbon of processing after absorption can cause secondary pollution; Micro-ionized air purification techniques can produce plasma by micro-ionization generator, with harmful dusty gas such as formaldehyde, benzene after a series of chain reactions, final formaldehyde and the benzene removed, thereby purify air, but its consumed energy is more, the plasma of generation may have a negative impact to health; Utilize formaldehyde eliminating agent, can remove formaldehyde by chemical reaction, but can cause secondary pollution, and such mode cures the symptoms, not the disease, formaldehyde easily discharges again.The present invention is directed to the various shortcomings of above method, consider energy-saving and environmental protection, the aspect such as attractive in appearance, a kind of low energy consumption has been proposed, zero energy consumption even, in conjunction with air plankton filter, normal temperature and pressure without photocatalysis Decomposition formaldehyde, indoor humidification in the air cleaning unit of one.
Summary of the invention
The present invention proposes a kind of air cleaning unit of catalytic decomposition formaldehyde, utilize chimney effect to make air from air inlet to the air outlet automatic flowing, through air filtration structure, remove airborne flue dust, large granular impurity, fiber cilium etc., pass through again the tunica fibrosa treatment facilities, effectively remove airborne harmful substance formaldehyde, and in air dried situation, air is carried out to humidification, through air circulation after a while, process, reach the purpose purified the air of a room, for people provide a kind of environment of healthiness.
The air cleaning unit of a kind of catalytic decomposition formaldehyde of the present invention, comprise shifting roller, chassis, air filtration structure, upper lower shell, tunica fibrosa treatment facilities, quiet fan, damping device, connection transition piece, cylindrical shell and colored silk ribbon.Wherein, shifting roller is arranged on chassis, can make device move to easily diverse location in indoor freedom, and chassis has air inlet.Air filtration structure, tunica fibrosa treatment facilities, quiet fan, damping device form purification assembly, are arranged on successively from the bottom up on cylindrical shell, and the axle collar place that is clamped on two joint cylindrical shells all is installed, and when changing and clearing up, two joint cylindrical shells are unloaded and get final product, convenient and swift.Connect by connecting transition piece between upper lower shell, thereby be circular by the square transition of lower shell, reduced the cylindrical shell area, also strengthened aesthetic property.Upper shell can increase arbitrarily joint number according to indoor situation, to strengthen chimney effect, obtains best clean-up effect, and upper shell can be taper in addition, thereby conveniently deposits after dismounting.On the top of upper shell, inner surface is stained with colored silk ribbon, in device, has air bottom-up when mobile, and colored silk ribbon hikes up and dances in the air, and shows device busy, and the vertical degree hiked up according to silk ribbon shows air velocity; When without Air Flow, colored silk ribbon, because Action of Gravity Field dangles in cylinder, can effectively show to have or not chimney effect.
The air cleaning unit of a kind of catalytic decomposition formaldehyde of the present invention, this device vertically is placed in indoor, because there are certain temperature difference in surface temperature and top layer temperature, air enters air filter through underpan air inlet, dust in air (as carbon granule, soil dust), large granular impurity (the metal superfine grits such as iron, aluminium), fiber cilium are filtered out, realize that the first order of air purifies.Then air is through the tunica fibrosa treatment facilities, on tunica fibrosa under the effect of catalyst, catalytic decomposition nuisance formaldehyde in the air, and, along with Air Flow has been taken away catabolite carbon dioxide and water, promoted catalyst to continue catalytic decomposition formaldehyde.Be up quiet fan again, this fan is determined whether using by the room air situation, when indoor upper and lower temperature difference larger, when the Air Flow in device presents obvious chimney effect, do not need to open fan, the work of device nature, realized the Zero-energy consumption of air cleaning; But when the little chimney effect of upper and lower temperature difference is not obvious, Air Flow a little less than, just need to open fan, air is flowed from lower to upper, make airborne formaldehyde touch catalyst and decompose, quiet fan power is lower, whole device low energy consumption work.
The air cleaning unit of a kind of catalytic decomposition formaldehyde of the present invention, its tunica fibrosa treatment facilities comprises tunica fibrosa grip block and formaldehyde catalytic purification fibre film, this film adopts the formaldehyde catalytic purification fibre of this seminar by melt electrostatic spinning method development, and (patent publication No.: CN102127823A) make, this fiber is by by MnO 2the composite catalyst particle directly mixes spinning with polymer after refinement and surface treatment, and its preparation technology is simple, and formaldehyde catalytic decomposition speed is fast, and clearance is high, and catalysis fibre is easy to knitting forming, and degree of soaping is high, and life cycle is long.
The present invention also has air humidifying function, when room air is drier, can open knob, allows the upper end water tank open, and the air stream after purification, through the water surface, is realized humidification; When the room air humidity, while not needing humidification, knob is turned to another side, make to revolve box and water tank closure, air flows through from space, can, by humidification, can not realize observing water level by pumping case simultaneously, add water or water tank cleaning.
When indoor top layer temperature is high, when surface temperature is hanged down, in apparatus of the present invention, can produce reverse chimney effect, now air will enter from upper end, from bottom, flow out.Airborne formaldehyde still can touch the tunica fibrosa treatment facilities and obtain catalytic decomposition, still has Air purification.
