Description
The tubular type air cleaner that separates housing is to be used as final stage in air conditioning and the air cleaning system to filter means, remove fine dust and bacterium in air intake or the air draft, (" air cleaning technical measures " according to the China that builds the publication in 1978 of worker publishing house advise first to have the inferior efficiently air cleaner of above filter efficiency, to particle diameter is the particulate of 0.3 μ m, the filter of counting efficiency between 90%～99.9% is inferior high efficiency filter, resistance is below the 15mm water column, to be different from efficient at the high efficiency particulate air filter of 99.91% above resistance below the 25mm water column).
Since the fifties, commercial high efficiency particle air filter (HEPA) appearred in the U.S., the inferior efficient above efficient filter of domestic and international filter paper type (except the electrostatic), mainly until whole employing glass fiber filter paper, pleated shape structure is seen Fig. 1.
Among the figure 1: the filter frame, wooden (thick 15mm) commonly used also has iron or aluminum; 2,2 ': sealing, wherein 2 is sealings of each folding filter paper openend, gluing, encapsulating is arranged, insert way such as glue, the easiliest from then on sew, 2 ' be that the initiating terminal of filter paper and clearing end usefulness sticker are on the frame inner surface; 3: demarcation strip; 4, filter paper; 5, end socket paper prevents that demarcation strip from scratching filter paper.
Fig. 2 is this filter perspective view.
The numeral explanation that indicates among the figure is the same.
More than referring to the book and the publication of external relevant air cleaning, for example Japan's ability in 1981 one system society version " air cleaning Ha Application De Block
Network ".
Domestic since " air cleaning technical measures " propose inferior high efficiency filter, the inferior high efficiency filter of two kinds of pleated shape structures of imitation high efficiency particulate air filter once appearred, promptly
ZKL(cotton linter fiber filter paper), 484 * 484 * 220(mm) 1000m per hour
3Air quantity, sodium flame method efficient (GB) (suitable)＞90%, resistance 98Pa(10mm water column with above-mentioned counting method efficient);
The GZH(glass fiber filter paper), 484 * 484 * 220(mm), 1000m per hour
3Air quantity, sodium flame method efficient 〉=95%, resistance 118Pa(12mm water column).More than draw self-built worker's publishing house's nineteen eighty-three publication " air conditioning design manual ".
But above inferior high efficiency filter unstable properties, so " clean technology " equipment patent by editorial office of clean technology association " clean technology " volume according to up-to-date publication, also remaining all-glass paper a kind of only who recorded on the № 1 in 1985, performance also becomes: sodium flame method efficient 90%, resistance 176.4Pa(18mm water column).About 200 yuan every of above high efficiency particulate air filters, inferior efficient 160 yuan every.
The tubular type air cleaner that separates housing be exactly structurally with filtrate on different with the pleated shape structure of the glass fibre that does not become above-mentioned decades, be that more economical practicality is beneficial to universal new air filter.
Calculate (see and build worker publishing house nineteen eighty-three version " air cleaning know-why ") according to theory, picture (contains in every litres of air 〉=grit of 0.5 μ m for 100,000 grades, be not more than 3500) rudimentary clean environment (be applicable to chemical fibre, part health pharmacy precision optical machinery department, zooming machine room etc.) just much of that with the filter of 95% counting efficiency, resistance low especially (the little blower fan of good adapted low noise) importantly, price is cheap, preferably just uses up unlike pleated shape and throws away.The purpose of this utility model will reduce filter resistance exactly significantly, reduces cost and operating cost morely.
Content of the present utility model is:
1. use low-resistance polypropylene fiber filter paper
2. filter paper is made tubular filter core
3. with the plastics cap stopper chimney filter is pressed on the base plate of punching
Below promptly constitute filter body.
4. outside body, add separate type housing (also can add fixedly housing),
5. efficient or efficient filtrate and middle effect or slightly imitate filtrate and combine the Asia; Do not increase volume, and play two kinds of filters.
Below 1.～4. adopted, 5. also adopted by the II type by the I type.
Fig. 3 is above-mentioned I type filter, and left part is a filter body, by base plate (plastic plate be plate with the band groove of mould compacting with weight reduction, also available five-ply board.A hundreds of hole is arranged on the plate) and a hundreds of chimney filter formation, on base plate, chimney filter only draws among the figure a part of chimney filter by plastics cap stopper jam-pack.Right part is the thin portion of chimney filter plug on base plate.Chimney filter scald the limit should with cap stopper on to play support vertical with fin.
Among the figure 6: base plate; 7: cap stopper; 8: chimney filter; 9: fin; 13: chimney filter scalds the limit.
Fig. 4 is above-mentioned plastics cap stopper and tab construction, and right part is burnt the signal of seam for the chimney filter both sides with scalding weldering.
The numeral explanation that indicates among the figure is the same.
Fig. 5 is the framed situation of filter body, and the housing on top is as bearer bar, and the housing of bottom is made the diffused air port of common usefulness, need not refill the air port like this below filter, changes the cartridge period of the day from 11 p.m. to 1 a.m and does not also change this air port.
Among the figure 10: housing, wooden or iron sheet system; 11: air port shape housing, the hole that band diffusion air-flow is used; Other numeral explanations are the same.
Fig. 6 is the thin portion of II type filter chimney filter plug on base plate, and right part is middle effect or slightly imitates filtrate and roll up naturally.
Among the figure 12: middle effect or slightly imitate filtrate; Other numeral explanations are the same.
As follows for the above the utility model content division:
1. filtrate: replace glass fiber filter paper with low-resistance polypropylene fiber filter paper.99.99% glass fiber filter paper is at standard ratio speed (0.06l/min.cm
2) the following about 49Pa(5mm water column of resistance), and equally the polypropylene fiber filter paper of efficient equally than the about 0.8～0.9mm water column of resistance under the speed; Glass fiber filter paper about 99.9%, the about 4mm water column of above-mentioned resistance, and the same about 0.5～0.6mm water column of polypropylene fiber filter paper resistance.This paper tape static is strong, more helps catching small-particle.This paper can scald weldering with hot pressing, and glass fiber filter paper is then impossible.This paper is cheap than all-glass paper.
2. filter core form: the method for scalding weldering with hot pressing is made the about 20～30mm of diameter to filter paper, and length is generally at the tubular filter core of 220mm with interior (thickness of high efficiency particulate air filter).Technology is much simpler than folding Zhe, glue envelope.The characteristics of chimney filter are much thinner than sack, and quantity is much more, and this just makes filter area more much bigger than bag configuration.Though for little but the soft and bad folding Zhe sealing of resistance and be the polypropylene fiber paper of individual moulding, have only the employing tubular-shaped structures, could all realize the purpose of talking about previously.
3. chimney filter fixing means: chimney filter is pressed in the hundreds of eyelet on the base plate one by one with the plastics cap stopper.The compression molding of plastics cap stopper, base plate also can be molded into plane or concave-convex type.Band monolithic fin works to support chimney filter on the cap stopper.Therefore whole filter is exactly that a base plate adds the some chimney filters that can change.
4. outer box form: housing can be made fixing, also can make to separate with base plate; The separate type housing can be made the framework that only plays the housing effect, and the same with the glass fiber filter paper high efficiency particulate air filter (seeing Fig. 5 top) also can make the divergent contour air port, then has protection housing and the two kinds of effects in air port (seeing Fig. 5 bottom) concurrently.
Below promptly constitute I type structure.
5. II type way: preposition prefilter all should be established in high efficiency particulate air filter and inferior high efficiency filter front, is generally medium effeciency filter.The utility model is if being rolled into nature with the thick continuous yarn non-woven fabrics of 3mm rolls up, and fills in the chimney filter that polypropylene fiber filter paper does, and top terminates in the cap stopper lower end, and some distances are arranged at the bottom of chimney filter at the bottom, otherwise will burst chimney filter.This nonwoven fabric roll promptly plays the effect of medium effeciency filter, can replace the single-blade sheet on the cap stopper to play a supportive role again, so also just simplified cap stopper.II type structure that Here it is.
I type inferior high efficiency filter result of the test is shown, is 484mm * 484mm at sectional area, and thickness is that 220mm and air quantity are 1000m
3Under these standard conditions of/h:
1. efficient: sodium flame method 95% to 99% is equivalent to count heavy efficient 100%;
2. resistance: 5～6mm water column
3. be more than 99.9% to the Escherichia coli filter efficiency, several to atmosphere bacterium filter efficiency is 100%.
The utility model is compared the characteristics that have with prior art:
1. resistance is little.Though the chimney filter gross area is about more than 30% of the folding Zhe shape filter paper gross area, used filter paper resistance has only 1/7～1/8 of glass fiber filter paper, so whole filtering material resistance is more much smaller than folding Zhe shape.Also the folding Zhe shape than the band demarcation strip is little for structural drag of the present utility model simultaneously.For 1000m
3The standard type filter of/h air quantity, the utility model structural drag experimental results show that and be no more than the 1.5mm water column, and folding Zhe shape reach 7～15mm water column.Therefore the utility model can reduce by 1/2～3/4 than the folding Zhe form drag of corresponding efficient, can adapt to the not high pressure head of little blower fan.Because general little fan pressure head has only 25～35mm water column, should consider that routinely 1 times of resistance of thick, middle and high (inferior high) tertiary filter is selected blower fan for use, wherein the about 4～7mm water column of low efficient filter initial resistance obviously is not all right.For the local cleaning equipment that is widely applied, all be furnished with little blower fan, often perplexed by pressure head is not enough.In addition, along with the requirement to cleaning of people and production generally improves, on air-conditioner, to install additional inferior efficient or high efficiency particulate air filter (even computer room peace air-conditioner in the past for example, but there is not control techniques, so air-conditioning result, aspect dust than air-conditioning is also not dirty), and the outlet overbottom pressure of air-conditioner is very little, makes to select for use the filter difficulty very big.Filter of the present utility model has been arranged, just can satisfy this and require.
2. without the glue envelope, both helped reducing cost, be beneficial to leakproof again.Owing to be difficult to obturage in filter paper folding Zhe end large tracts of land glue envelope, so filter seepage person herein itself is a lot.Leak detection and leak stopping are all very difficult after good and sound; Broken if particularly roll over the surface of Zhe inside on the filter paper surface, except broken very little also can repair, have to abandon whole filter.Test shows, the utility model chimney filter scalds behind the limit very solid, can not tear open.Every filter can be economized the fluid sealant about 2 kilograms.Because cap stopper and eyelet all are the mould punch formings, can accomplish good cooperation, generally compress promptly salablely so test shows cap stopper, coat paint again twice at shade, perhaps dial loose cap stopper measurement result is not all had influence.Illustrate that sealing meets the demands.
3. structure, technology are simple, and cost is low.Whole filter is exactly that a base plate adds some chimney filters.Housing, can connect frame when then removing initial purchase and buy as protection, installation framework as only, only needs the base plate of tape swapping chimney filter later on; For the strong unit of installation and maintenance strength even can change chimney filter certainly, base plate does not repurchase.Housing also can be applying unit and saves the money of purchasing the air port in addition as making the air port.Base plate is except that the first time, mould took, and because of a hundreds of hole is arranged, so material consumption is very low, cost has also just reduced.A cap stopper is at present if each about 6 minutes of small lot batch manufacture also can reduce more than 20% when in enormous quantities surplus in the of 300; Filter paper needs 4m
2More, about 14 yuan.Add that without glue no demarcation strip is so whole I type inferior high efficiency filter only need be sold 90 yuan (housings sell 20 in addition surplus yuan) when small lot batch manufacture at present.Expensive 10 yuan at most of I type high efficiency particulate air filters than this.And the II type that inferior efficient and middle effect combines spend more ten than I type surplus yuan cost, and saved the expense of a medium effeciency filter.
Even only change base plate at every turn, this base plate also can reclaim, because take down chimney filter base plate there is not any damage, and the filter of folding Zhe shape can only all be abandoned behind the full dirt of collection, framework, demarcation strip etc. all can not be taken usefulness again apart, in case take apart by force, filter promptly disintegrates, so the utility model only needs renew cartridge, each about 70 yuan.
4. because every chimney filter is very little, institute is so that utilize filtrate even broken filtrate in addition, and folding Zhe shape then must be with whole volume filter paper, and because the filter size difference will be downcut the very wide a section of rolling filter paper sometimes, give it up.
5. every chimney filter all is convenient to observe check before installation, finds that later on that pipe break, can change at any time, and the surface leak detection and the leak stopping of folding Zhe shape all bothers, and often is difficult to repairing if any the place of making a mess of (particularly in the depths) in installation.
6. the efficient and middle effect of II type (Asia) is integrated in one, and does not increase the volume of former I type.Imitate filtrate during 3mm is thick and make folding Zhe shape filter, at 1000m
3Under/h air quantity and the filter area condition more than 3 square metres, resistance 2.5mm water column, sodium flame method efficient is more than 50%, and dust containing capacity 310 restrains; The middle effect filter volume that adds in the II type now, filter area 4 square meters are many.In addition, install and two filters of peace are become only to pacify a filter also simple.If also will use preposition prefilter, then the II type has also increased dust containing capacity than I type, has prolonged than life-span of former I type, and concerning whole cleaning system, this is also more favourable.
Realize that the utility model approach has following several respects.
1. manufacture the low-resistance inferior high efficiency filter.
Popularization along with the air cleaning technology, growing field adopts this technology with raising work and product quality, for example hospital operating room just is sought after building up the cleaning sterile operating room, vast food industry, pharmaceuticals industry, superior cosmetics industry, chemical fibre industry or the like all need clean technology, but clean level can be than electronics industry low slightly, if then dislike waste,, the inferior high efficiency filter of a kind of efficient between height, middle effect need object so becoming with high efficiency particulate air filter.In addition, in the air-conditioning system and air-conditioner that the past is general, only be provided with thick effect even worse filter.These several years external investigation proofs, operation air-conditioning system and air-conditioner for many years, it is a lot of to carry disease germs in air-supply, and this original bacterium, mainly comes the bacterium of self-reproduction in system and equipment inwall in air, the people has been constituted to cause a disease threaten.So point out in general air-conditioning system, to adopt the demand of high middle effect even more high efficiency filter more and more obvious abroad with the Chinese who gives lectures that comes back home from external information.Because it is big more than 1 times that the bacterium particle is mainly 0.5 μ m particle than removing object common in the air, so inferior high efficiency filter obviously is suitable.And aforementioned domestic existing be called the Asia efficiently filter and high efficiency particulate air filter do not have what difference, just used same a kind of filter paper of poor performance.
2. manufacture common high efficiency particulate air filter
With the high efficiency particulate air filter that 49 polypropylene fiber filter paper are done, also little and cheap than the high efficiency particulate air filter resistance that all-glass paper is done, but the antistatic property of 49 polypropylene fibre paper requires further improvement, it is stable to make it the long period.
3. manufacture 0.1 μ m super high efficient filter
If further reduce the polypropylene fiber diameter, and can expect with the high efficiency particulate air filter that special thickening polypropylene fiber paper is done and to become 0.1 μ m high efficiency particulate air filter that promptly the filter efficiency to 0.3 μ m particle can reach 79, may be above 59 to the efficient of 0.1 μ m particle.Present glass fiber filter paper 0.1 μ m super high efficient filter appearance in the world is the thing of the eighties also, is representing the most advanced level of high efficiency particulate air filter, by super large-scale integration production is badly in need of.
Resistance at these 2 layers of paper under the standard filtering velocity is about the 1.6mm water column, and 0.1 μ m all-glass paper resistance is 11.7mm water column (the used filter paper of 0.1 μ m super high efficient filter that cleaning equipment factory in Chongqing is tested and appraised recently), make the filter of 610mm * 610mm * 150mm with it, the about 26mm water column of resistance, so as the 0.1 μ m extra-high-speed of making the chimney filter shape of above-mentioned size with polypropylene fiber filter paper is imitated filter, because its structural drag is original just than rolling over the little of Zhe shape, and (this is for standard size in 610 * 610 * 150 to 484 * 484 * 220 the cross section of passing through, size when also being the test of above-mentioned the utility model) strengthens, reduce by the degree of depth, so structural drag also should reduce, even the filtrate gross area is about 40% of folding Zhe shape, but drag overall also will have the reduction of certain degree.According to the Chongqing cleaning equipment factory report of opening evaluation meeting in January, 1986, all-glass paper 0.1 μ m super high efficient filter is 600 yuan one, japanese product is 60,000 yen and is roughly equal to 940 yuan one, and by the 0.1 μ m super high efficient filter that the utility model is manufactured can be the former half in addition lower.
