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 the requirement of health, and room air pollution is that people are extremely concerned about and problem demanding prompt solution.The kind of indoor pollutant can reach thousands of kinds, such as kitchen oil flue dust, and various ciliums floating in air, the formaldehyde that ornament materials discharges, ammonia etc., these all allow the healthy of people make the matter worse.In numerous pollutant, the adverse effect of formaldehyde to people's health is mathematical.It is except having stronger bond properties, also has and strengthens the hardness of sheet material and insect protected, corrosion-resistant function, generally all contains formaldehyde in the plastics, heat-barrier material and the Wood-based Panel Furniture that therefore use at ceiling at home, floor, wall veneer.Long Term Contact low dosage formaldehyde can cause the disorder of chronic respiratory disease, feminine menstrual, pregnancy syndrome, causes the reduction of neonate's physique, chromosome abnormality, even causes nasopharyngeal carcinoma.In addition, dry air, especially winter room heater, air-conditioning effect, air oxygen detrition, also has 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 removing formaldehyde also has a variety of.Wherein, active carbon absorption process is simple, but easily reaches capacity, and the active carbon after process absorption can cause secondary pollution; Micro-ionized air purification techniques can produce plasma by micro-ionization generator, with the harmful pollution such as formaldehyde, benzene gas after a series of chain reaction, final removal formaldehyde and benzene, thus 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 is cured 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, propose a kind of low energy consumption, even zero energy consumption, in conjunction with air plankton filter, normal temperature and pressure without photocatalysis Decomposition formaldehyde, indoor humidification in one air cleaning unit.
Summary of the invention
The present invention proposes a kind of air cleaning unit of catalytic decomposition formaldehyde, chimney effect is utilized to make air from air inlet to air outlet automatic flowing, through air filtration structure, remove the flue dust, large granular impurity, fiber cilium etc. in air, again through tunica fibrosa treatment facilities, harmful substance formaldehyde in effective removal air, and in air dried situation, humidification is carried out to air, through air circular treatment after a while, reach the object 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, comprises 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, and device can be made freely to move to diverse location easily in indoor, 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, all install the axle collar place being clamped on two joint cylindrical shells, are unloaded by two joint cylindrical shells when changing and clear up, convenient and swift.Connect by connecting transition piece between upper lower shell, thus be circular by the square transition of lower shell, reduce cylindrical shell area, also enhance aesthetic property.Upper shell can increase joint number arbitrarily according to indoor situations, and to strengthen chimney effect, obtain best clean-up effect, upper shell can be taper in addition, thus conveniently deposits after dismounting.Be stained with colored silk ribbon at the top inner surface of upper shell, when there being the bottom-up flowing of air in device, colored silk ribbon hikes up and dances in the air, and shows device busy, and according to the vertical degree display air velocity that silk ribbon hikes up; When flowing without air, colored silk ribbon, because Action of Gravity Field pendency is in cylinder, can effectively show with or without chimney effect.
The air cleaning unit of a kind of catalytic decomposition formaldehyde of the present invention, this device is vertically placed in indoor, because surface temperature and temperature of top exist certain temperature difference, air enters air filter through underpan air inlet, dust in air (as carbon granule, soil dust), large granular impurity (metal superfine such as iron, aluminium grit), fiber cilium are filtered out, realizes the first order purification of air.Then air is through tunica fibrosa treatment facilities, on tunica fibrosa catalyst effect under, nuisance formaldehyde in catalytic decomposition air, and taken away catabolite carbon dioxide and water along with air flowing, facilitates catalyst and continues catalytic decomposition formaldehyde.Be up quiet fan again, this fan is determined whether using, when indoor upper and lower temperature difference is larger by room air situation, when air flowing in device presents obvious chimney effect, do not need to open fan, device works naturally, achieves the Zero-energy consumption of purification of air; But when the little chimney effect of upper and lower temperature difference is not obvious, air flowing is more weak, just need to open fan, air is flowed from lower to upper, and make the formaldehyde in air 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, the formaldehyde catalytic purification fibre (patent publication No.: CN102127823A) that this film adopts this seminar to be developed by melt electrostatic spinning method obtains, and this fiber is by by MnO 2composite catalyst particle directly mixes spinning after refinement and surface treatment with polymer, its preparation technology is simple, and formaldehyde catalytic decomposition rate 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, and allow upper end water tank open, the air after purification flows through the water surface, realizes humidification; When room air is moist, when not needing humidification, knob is turned to another side, make to revolve box and close with water tank, air flows through from space, can not can be realized observing water level simultaneously, add water or water tank is cleared up by humidification by pumping case.
When building overlay temperature is high, when surface temperature is low, can produce reverse chimney effect in apparatus of the present invention, now air will enter from upper end, flow out from bottom.Formaldehyde in air still can touch tunica fibrosa treatment facilities and obtain catalytic decomposition, still has Air purification.
