The primary side (suction side) of circulating pump 8 is connected with circulating tank 7 via pipe arrangement 13, and the primary side (ejection side) of circulating pump 8 is connected with spreader nozzle 6 via pipe arrangement 14, thereby, it is possible to make rinse water circulate.In the present embodiment, the outside of housing 2 is located at by circulating pump, but circulating pump also can be located at the inside of housing 2, as long as it can make rinse water circulate.In addition, pump during circulating pump 8 also can be provided in circulating tank 7 water.
As long as being contained in circulating tank 7, for purifying air the water of rinse water cleaning, being not particularly limited, running water, well water, distilled water, pure water and brine electrolysis etc. can be used.
Further, air cleaning unit 1 has water fender (splash guard) 15, and the top of spreader nozzle 6 is located at by this water fender 15, for preventing the dispersing of spray water from spreader nozzle 6.In addition, in order to be removed by a large amount of moistures contained in the air after being purified by gas-liquid contact mode, also the humidity regulation parts such as desiccant wheel (desiccant rotor) can be set above water fender 15.
In addition, the nearside by exhaust outlet 4 above water fender 15 is provided with air blast 16, and this air blast 16 is for applying driving force upward to the air after air inlet 3 importing and discharge by the air behind gas-liquid contact portion 5 from exhaust outlet 4.In addition the air after importing from air inlet 3, also can substitute air blast 16 and will air be used for be located at from the exhaust component that exhaust outlet 4 is discharged the outside of housing 2, as long as can be discharged from exhaust outlet 4 by this exhaust component.
Next, the purification of air action of the air cleaning unit 1 using present embodiment is described simply.
When air blast 16 works, housing 2 inside becomes decompression state, and the air that purify is directed in housing 2 by from air inlet 3.Air after importing applied driving force upward by air blast 16 and from bottom to up housing 2 internal flow and arrive gas-liquid contact portion 5.
On the other hand, the rinse water be stored in circulating tank 7 is supplied to spreader nozzle 6 by circulating pump 8.The rinse water being supplied to spreader nozzle 6 utilizes spreader nozzle 6 spray to gas-liquid contact portion 5 and kept by the fiber assembly in gas-liquid contact portion 5.
There is gas-liquid contact at the fiber assembly place in gas-liquid contact portion 5 in the air come that rises from the below in gas-liquid contact portion 5, the particulate matter in air, gas shape chemical substance are removed by rinse water.Air after purification is discharged from exhaust outlet 4 by air blast 16.
Next, the structure of the fiber assembly being used as gas-liquid contact portion 5 is described with reference to Fig. 2 A and Fig. 2 B.Fig. 2 A is the general profile chart of the fiber assembly forming gas-liquid contact portion 5, and Fig. 2 B is the general profile chart of the structure in the gas-liquid contact portion 5 representing present embodiment.
Forming the fiber assembly 50 in gas-liquid contact portion 5 is by by curved for synthetic resin working into coil (Japanese: カ ー Le shape) and by a part for fiber bonding, the component that is formed as three-dimensional nonwoven cloth-like mutually.The fiber being processed to curling shape of fiber assembly 50 configures unevenly, and the major part of the tip portion (cut-off parts) of this fiber is positioned at side, a face.Thus, as shown in Figure 2 A, a face 50a of fiber assembly 50 is low-density and has (crude and rough) shape that band rises and falls, another face 50b of fiber assembly 50 is high density and has the shape of smooth (flat), and fibre density is different on the thickness direction of another face 50b from a face 50a.In the present embodiment, the smooth face 50b to fiber assembly 50 sprays rinse water, and air is flowed into from crude and rough 50a.That is, fiber assembly 50 is with crude and rough 50a is formed " lower surface " and the mode that smooth face 50b is formed " upper surface " is located in air cleaning unit 1.
When spraying rinse water to such fiber assembly 50, utilizing smooth upper surface 50b to promote the decentralized of rinse water, thus rinse water is kept in the mode of the upper surface 50b throughout fiber assembly 50.The rinse water that remain under the effect of gravity and capillarity along fiber under lower surface 50a effluent.Its result, can realize uniform water conservation state at the upper surface 50b of fiber assembly 50, and can promote to dewater (Japanese: water cuts れ) at lower surface 50a.
As the raw material of the fiber of formation fiber assembly 50, as long as it can be processed to the material of fiber, the polyamide such as such as fully aromatic polyamide, nylon 6, nylon66 fiber can be listed; The polyester such as PETG, polybutylene terephthalate (PBT); Polyvinyl chloride, Vingon, Kynoar, polytetrafluoroethylene (PTFE) etc. gather (halogenated alkenes); The nitrile such as polyacrylonitrile, polymethacrylonitrile system monomer; Polyvinylesters and its hydrolysates such as polyvinyl acetate, polyvinyl proprionate, polyvinyl alcohol; The cellulose families such as cellulose, acetylcellulose, artificial silk; The polyolefin such as polyethylene, polypropylene, vinyl-vinyl acetate copolymer.
In addition, because fiber assembly 50 is used as gas-liquid contact portion 5, therefore expect that fiber assembly 50 is by having chemical resistance and there is no that absorptive fiber is formed.From this point, preferably use the Vingon etc. in the raw material of the above-mentioned fiber enumerated.
In addition, as the associated methods (preparation method of aggregate) of fiber assembly 50, can list utilize heat to make fibers melt and combine heat bonding (thermal bond) method, use bonding agent to the chemical adhesion that fiber is combined (chemical bond) method and by being needled into of barb of band any one method such as the needle point method that utilizes mechanical means that fiber is combined.
Such as, as above-mentioned fiber assembly 50, the Saran-Lock (Japanese: サ ラ Application ロ ッ Network, registration mark) of Asahi Chemical Industry ホ ー system プ ロ ダ クツ Co., Ltd. (Asahi Kasei Home Products Corporation) can be listed.Saran-Lock is that fiber by raw material itself being had very high anti-flammability and Saran (Japanese: サ ラ Application, registration mark) fiber are spring-like stample fiber and are processed into nonwoven cloth-like and utilize Saran Latex (Japanese: サ ラ Application ラ テ ッ Network ス) to cover Saran and the three-D non-woven cloth combined with Saran.Saran-Lock has larger space and surface area simultaneously, has the structure that flowing resistance is less, filter efficiency is excellent and control of dust capacity is larger, therefore preferably uses.
As shown in Figure 2 B, the gas-liquid contact portion 5 of present embodiment has duplexer 51, and this duplexer 51 is by having the structure same from the fiber assembly 50 shown in Fig. 2 A respectively and different stacked three layers of the two kinds of fiber assemblies of average fiber density form.Specifically, gas-liquid contact portion 5 has the duplexer 51 be made up of upper strata 52, intermediate layer 53 and lower floor 54, this upper strata 52 is made up of the fiber assembly (low-density fibre aggregate) that average fiber density is relatively low, this intermediate layer 53 is made up of the fiber assembly (high-density fiber aggregate) that average fiber density is relatively high, and this lower floor 54 is made up of the low-density fibre aggregate same with upper strata 52.Herein, " average fiber density " represents that fiber, with the intensive configuration of much degree, can represent with the surface area of the fiber of such as per unit volume (specific area) in whole fiber assembly.
The low-density fibre aggregate on upper strata 52 can make the rinse water sprayed from spreader nozzle 6 disperse equably and keep this rinse water at smooth upper surface.This rinse water be maintained uniformly is under the flows by action of gravity and capillarity and by the higher whole intermediate layer (high-density fiber aggregate) of the removal capacity that is supplied to fine grained, gas shape material etc. equably.Its result, can make intermediate layer (high-density fiber aggregate) effectively play higher removal capacity for fine grained, gas shape material etc.In addition, the average fiber density due to upper strata 52 is low-density, and therefore, the water conservation state at upper surface place can not become and causes the pressure loss to rise such excessive water conservation state (water seal state).
The high-density fiber aggregate in intermediate layer 53 moderately can keep the rinse water flowed down from upper strata 52 on the whole, thus has higher removal capacity for fine grained, gas shape material etc.In addition, by making water droplet miniaturization, also can increase gas liquid interfacial area, thus the removal capacity for fine grained, gas shape material etc. can be improved.
The smooth upper surface of the low-density fibre aggregate of lower floor 54 is adjacent with intermediate layer 53, therefore, it is possible to make the rinse water that remain by the high-density fiber aggregate in intermediate layer 53 flow down.Its result, has played the effect moderately maintaining the water conservation state in intermediate layer 53.In addition, the low-density fibre aggregate of lower floor 54 also has the rectified action processed air flowed into from lower surface being carried out to rectification.
In addition, rolling of water droplet is also produced at the fiber assembly upper surface of each layer 52 ~ 54.Thereby, it is possible to increase processed touch opportunity between air and rinse water further, thus the removal capacity for fine grained, gas shape material etc. can be improved further.
As mentioned above, the gas-liquid contact portion 5 of present embodiment has and can suppress the rising of the pressure loss caused by water seal as much as possible and the structure increasing the specific area of packing material (fiber assembly).Thereby, it is possible to increase processed touch opportunity between air and rinse water, thus the higher removal capacity for fine grained, gas shape material etc. can be guaranteed.In addition, structure as described above is being easy to the fine grained captured by fiber assembly, gas shape material etc. to rinse out on this aspect also have superiority.
In addition, in the present embodiment, gas-liquid contact portion 5 is made up of the duplexer of different stacked three layers of the two kinds of fiber assemblies of average fiber density, but is not limited thereto.The average fiber density of the fiber assembly used also more than two kinds, such as, can be able to be 3 kinds.In addition, also can by stacked for fiber assembly more than 4 layers.But, in this case, preferably make the undermost fiber assembly of formation be the fiber assembly that average fiber density is minimum.Its reason is, at orlop, the lower surface of fiber assembly can be prevented by water seal, thus suppresses the rising of the pressure loss.Further, the fiber assembly forming the superiors is also preferably the minimum fiber assembly of average fiber density.Its reason is, the superiors closest to air blast the most easily become negative pressure, if make the superiors be the fiber assembly that average fiber density is higher, then easily makes the water conservation state at fiber assembly upper surface place produce uneven.
Herein, the preferable range of the sprinkling flow of the rinse water of spraying to gas-liquid contact portion 5 is described with reference to Fig. 3.
Fig. 3 be based on the gas-liquid contact portion 5 shown in Fig. 2 B, by the fine grain clearance of particle diameter 1 μm and sulfur dioxide (SO
2) both clearances carry out composition relative to the sprinkling flow L from spreader nozzle 6 with the ratio L/G of air quantity (process air quantity) G of the air through gas-liquid contact portion 5 and the chart that obtains.In addition, the data of the clearance shown in Fig. 3 be change with the condition of embodiment 5 described later the ratio L/G spraying flow L and process air quantity G after carry out measuring and the result that obtains.
As shown in Figure 3, if make process air quantity G be certain, then along with sprinkling flow L becomes large, SO
2clearance, fine grained clearance increase, but pressure reduction (pressure loss) also can similarly increase.In addition, tail off if spray flow L, then have such worry: not only can not play removal capacity fully, and the fine grained captured, gas shape material etc. lodge in gas-liquid contact portion 5.Thus, preferably spray flow L and process the ratio L/G of air quantity G in the scope of 0.5 ~ 3.0.If than L/G more than 0.5, then can remove SO fully
2, fine grained, if than L/G below 3.0, then can suppress the rising of pressure reduction (pressure loss) play removal capacity fully.
On the other hand, the air velocity (linear flow rate) at the upper surface place in preferred gas-liquid contact portion 5 is have more than the free-falling speed of the water droplet of minimum drop diameter in the water droplet sprayed the upper surface in gas-liquid contact portion 5.Thereby, it is possible to make a part for the water droplet that the upper surface in gas-liquid contact portion 5 sprays floating.Floating water droplet on one side STOCHASTIC DIFFUSION collides with other water droplets on one side and becomes greatly and fall to the upper surface in gas-liquid contact portion 5.Therefore, it is possible to evenly spray rinse water impartially further to the upper surface in gas-liquid contact portion 5, thus can promote that rinse water intersperses among the upper surface in gas-liquid contact portion 5 equably.Further, floating water droplet contacts with air and sweeps along the fine grained, the gas shape material that contain in air, while fall to the upper surface in gas-liquid contact portion 5, therefore can also improve fine grained clearance, gas shape material clearance.
In addition, as mentioned above, the part of the spray water from spreader nozzle (spray nozzle) 6 under the effect of the lower surface leaked-in air air-flow from gas-liquid contact portion 5 floating and rolled-up when, preferably the water fender 15 being located at the top of spreader nozzle 6 is located at the position that rolled-up small water droplet arrives.Thus, by utilizing water fender 15 to catch the small water droplet rolled by air draught, the water droplet in processed air can be removed.Further, form moisture film at the lower surface of water fender 15 because of small water droplet, this moisture film also can remove fine grained, gas shape material.But, if the lower surface of water fender 15 becomes excessive water conservation state, then can become fan resistance and make the pressure loss increase.Thus, conduct oneself with dignity when the thickness of moisture film is thickening to make the moisture film of the lower surface being formed at water fender 15 and exceed surface tension and fall with the form of drop, preferred water fender 15 uses the fiber assembly same with the fiber assembly forming gas-liquid contact portion 5 and arranges in the mode making crude and rough face become lower surface.According to same reason, preferably water fender 15 is located at the position directly do not contacted with the spray water from spreader nozzle 6 when there is not air draught.
In addition, when the fiber assembly shown in Fig. 2 A being used as described above water fender 15, the fiber assembly that preferred use average fiber density is higher than the average fiber density of the low-density fibre aggregate on the upper strata 52 in formation gas-liquid contact portion 5, such as, preferably use the high-density fiber aggregate forming intermediate layer 53.Water fender 15 only keeps rolled-up small water droplet, thus, can not become water seal state, and the pressure loss also can not be made to increase.Therefore, in order to utilize the moisture film of the lower surface being formed at water fender 15 to remove fine grained, gas shape material expeditiously, preferably high-density fiber aggregate is used as water fender 15.
Next, specific embodiment is enumerated to further describe the present invention.
