Description
Technical field
The utility model belongs to air conditioner technical field, relates to a kind of Fresh air handling units using wool media filtration outdoor air.
Background technology
In half traditional central air-conditioning system, each room must be sent into the new wind in a certain amount of outdoor and maintain indoor minimum sanitary standard while fan coil cooling indoor return air.Fresh air handling units is the airhandling equipment of the outer new wind of process chamber, and the main temperature reducing outdoor new wind filters the air clean hygiene ensureing to send into room simultaneously to the new wind in outdoor.
City haze weather takes place frequently in recent years, and its reason is that outdoor particle concentration is large.If air high for outdoor particle PM2.5 (desirable particle size is less than 2.5 μm) concentration is directly sent into indoor by Fresh air handling units, indoor occupant can be endangered healthy, so Fresh air handling units is all equipped with air cleaner usually.
Cheap first efficiency filters is installed in existing Fresh air handling units usually, as the filter that filtrate material is polypropylene fibre Nomex, when wind speed is 0.2 ~ 0.8 meter per second, this filter can filter the particle of 5 μm and cheap, but this filter can not remove the particle of PM2.5 in outdoor air, importantly can not to degrade pernicious gas and VOC (Volatile Organic Compounds is called for short VOCs).If install medium effeciency filter in Fresh air handling units, the particle of in air 1 ~ 5 μm can be removed, but price is more expensive, the VOCs in outdoor air can not be removed equally.
Utility model content
The purpose of this utility model is to provide a kind of Fresh air handling units using wool media filtration outdoor air, and solving filter in the Fresh air handling units existed in prior art can not the effectively particle of PM2.5 and can not degrade pernicious gas and VOC problem in filter chamber's outer air.
The technical scheme that the utility model adopts is, a kind of Fresh air handling units using wool media filtration outdoor air, comprise housing and be arranged on new air-valve, filter, surface cooler, humidifier and the pressure fan in housing, one end of housing is air inlet, the other end is pressure fan, is disposed with new air-valve, filter, surface cooler and humidifier along wind path trend in housing; Filter comprises filter housing and is arranged on the wool needled felt filter pad on frame, and wool needled felt filter pad is arranged on filter housing in the mode of multilayer folding.
The beneficial effects of the utility model are, the utility model adopts wool needled felt as the filter of filtrate, this filter is to the filter efficiency 10% ~ 40% of pellet, be 34% ~ 69% to the filter efficiency scope of new wind, filtration resistance is at below 120Pa, like this, outdoor air through purification laggard enter indoor, indoor PM2.5 concentration reduces greatly, and can degrade pernicious gas and VOC (VOCs), make people can breathe clean air, thus ensure health.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The Fresh air handling units that can purify air of the present utility model, its structure as shown in Figure 1, the new air-valve 1, filter 2, surface cooler 3, humidifier 4 and the pressure fan 5 that comprise housing 6 and be arranged in housing 6, one end of housing 6 is air inlet 7, the other end is pressure fan 5, is disposed with new air-valve, filter 2, surface cooler 3 and humidifier 4 along wind path trend in housing.
As shown in Figure 2, the wool needled felt filter pad 8 that filter 2 comprises filter housing 9 and is arranged on frame, wool needled felt filter pad 8 is arranged on filter housing 9 in the mode of multilayer folding.
Wool fiber is a kind of natural protein fibre, a kind of multi-cellular structure body that it is is main chain by more than 20 kinds of a-amino acids with many contractings amino acid chain that peptide key joint is formed.Wherein with sulfur-containing amino acid-cystine, dihydroxylated acid-east gate, sky propylhomoserin, glutamic acid, diamino acid-Song propylhomoserin, arginine etc. are main, simultaneously, arginine belongs to basic group amino acid, and east gate, sky propylhomoserin and glutamic acid belong to acidic groups propylhomoserin, and two kinds of group contents are roughly the same, so wool protein is not only containing alkalescence but also containing acid, belong to amphiphatic molecule.Wool has some and is conducive to very much as filtering the performance of felt pan, first, it has anti-flammability, wool fiber is the fiber that in all textile fabrics, flame-retarding characteristic is best, this characteristic gives the credit to its some natural performances, and the above feature of wool fiber is allowed to condition at the fire prevention of air-conditioning system and smoke evacuation aspect has actual using value.Secondly, wool also has antibiotic property, the anti-microbial property of wool fiber is just formed in its growth course, and a focus of air cleaner material is exactly that exploitation has the material of natural antibacterial performance to replace common filtering material in recent years, and wool fiber can meet the demands well.And wool is fine to the absorption property of indoor pollutant, because wool protein is not only containing alkalescence but also containing acid, belong to amphiphatic molecule.So amino (-NH can be there is in wool surface
2) be easily combined with formaldehyde and generate (-NHCH
2oH), disulfide bond (-S-S-) and SO can be there is again
2reaction generates (-S-SO
3h), these two kinds absorption all belong to chemisorbed, are Irreversible Adsorption.Formaldehyde adsorption can adsorb SO again
2.
So, based on the above characteristic of wool fiber, make wool needled felt filter pad have unique filterability.At fine particle adsorption and carry a lot of harmful substance, comprise the inorganic matters such as each heavy metal species, polycyclic aromatic hydrocarbon type organic, formaldehyde, SO
2, NO
2deng pernicious gas, wool surface has unique physicochemical properties, to the pernicious gas in air as formaldehyde, SO
2have and adsorb and the effect purified, therefore contribute to a certain extent improving the clean-up effect to pellet; And fibre fineness is less, the fiber number in unit volume is more, better to the filter effect of particle.
Fig. 3 is the filter efficiency curve of wool needled felt filter pad and polypropylene fibre Nomex, and wool needled felt filter pad is higher to PM2.5 particle filter efficiency than polypropylene fibre Nomex, and has the effect of removing formaldehyde and sulfur dioxide.In actual applications, to wool needled felt filter pad through nano-TiO
2its filter efficiency can be significantly improved after arrangement.And the filter efficiency of polypropylene fibre acupuncture class filtering material is lower, resistance is also very little, and this is relevant with the internal structure that it comparatively loosens, when the grammes per square metre of polypropylene fibre acupuncture class filtrate doubles, and filter efficiency not obvious increase, but resistance increases considerably.
The course of work of the present utility model is, outdoor air is under the swabbing action of Fresh air handling units pressure fan 5, enter from the air inlet of Fresh air handling units shell one end and first enter through new air-valve 1, then wool filter device 2 is flow through through the outdoor air containing pellet, under the effect of filter 2, after outdoor pellet and VOCs are effectively filtered by wool needled felt filter pad, air flows through surface cooler 3 and humidifier 4 again, is finally sent into indoor by pressure fan 5.
