Description

Micropore bubbling formula air purifier

Technical field

The present invention relates to a kind of gas cleaning plant, belong to the technical field of green technology and household electrical appliance, family expenses or commercial air purifier can be applied to.

Background technology

Air purifier is the purifier of various solid-state, the gaseous contaminant removed in air, and conventional air purifying process has filtering technique, adsorption technology, absorption techniques, plasma technology, anion technology, chemical catalysis, photocatalysis, electrostatic precipitation, ozone technology etc.High efficiency filter technology in these technology and adsorption technology stable performance, but the filter material life-span is short, and need periodic replacement, use cost is very high; Catalysis technique, plasma technology, electrostatic technique are better for the clean-up effect of specific source, use limitation very large, are usually applied to composite type purifying device, are seldom used alone.

Wet purification is not only important industrial waste gas treatment technology, is also used widely in recent years in family expenses and business air purified product.Wet purification passes through the contact of water or other absorbing liquid and gas, utilize the effect trapping grits such as the inertial collision between drop and particle, diffusion, interception, effectively can removing liquid state or the solid contaminant of 0.1 ~ 20 micron, also removing gaseous contaminant by absorbing.It is with water droplet by water that wet scrubbing purifies the most frequently used technology path, the state of water smoke directly sprays the passage of gas flow warp, or the filter screen be sprayed in gas channel, filter core, humidification disk forms liquid film, caught by gas-liquid contact and absorb the pollutant in air, its typical apply is as Chinese patent " humidifier and air purifier (CN101532712) ", " there is the air purifier (CN101301555) of humidification function ", " air purifier and condenser (CN101639250) ", " a kind of taper-shaped internal spiral water-absorption type rinsing air purifying device (CN201218573Y) ".But the usual gas liquid interfacial area of spraying method is little, and time of contact is short, thus once not high by purification efficiency, normal and other technical combinations uses.The another kind of technology path of wet scrubbing purification is Bubbling method, air is pressed into bubbling in water, as Chinese patent " swirl air purifier (CN101737210A) "; Or bubble, as Chinese patent " a kind of Swashing type indoor air purifier (CN101498483) " with air impulse liquid level.Bubbling method gas-liquid contact is comparatively abundant, but gas phase drag will reach 500 ~ more than 1000Pa, need high-static pressure fan even air pump carry out gas conveying, be difficult to drop into practical application.The clean cluster ion technology of Sharp Corp's exploitation is different from traditional wet purification method, hydrone in air is ionized into H free radical and OH free radical, wrap up hydrone again, to bacterium, virus, there is very strong inactivation capacity, such as Chinese patent " method for disinfection, ion generating device, ion generating device and conditioner (CN101396567) ".

In industrial waste gas process, fountain process for purifying is sprayed downwards by spray head, atomising head after relying on the power of water pump water extraction to be risen, or is sprayed at and baffle plate forms cascade flows down, and air flows from bottom to top, with liquid phase counter current contacting under blower fan suction.Operating condition is gas flow rate 0.5 ~ 2m/s, water consumption 0.5 ~ 1.5L/m3, the pressure loss 100 ~ 500Pa, and its structure is simple, and resistance is little, but equipment is huge, and water consumption is large, and efficiency of dust collection is lower.A kind of auto-excitation type process for purifying, after rocket motor impacts the water surface downwards, evokes a large amount of sprays by the throttling of S shape passage, due to the collision between grit and drop, interception and cohesion, dusty gas is purified.Operating condition is gas flow rate 10 ~ 20m/s, water consumption 0.05 ~ 0.1L/m3, the pressure loss 1000 ~ 1500Pa, and efficiency of dust collection can reach 95%, its compact conformation, and floor space is little, and load adaptability is good, and water consumption is few, but the pressure loss is very large.A kind of plate column washing, purifying technique, a large amount of pore air feed that column plate distributes passes through mutually, the bubble level of gas-liquid contact on column plate carries out, liquid phase is sprayed downwards from tower top by water pump pumps, air-flow is through forming a large amount of bubble during liquid layer and constantly breaking and upgrade, in bubbling area by under dust catching, the normal multilayer column plate that adopts is to improve purification efficiency.Operating condition is gas flow rate 1 ~ 3m/s, water consumption 0.1 ~ 0.3L/m3, the pressure loss 300 ~ 1000Pa.Plate column is divided into aperture sieve plate (3 ~ 8mm) and macroporous plate (10 ~ 25mm) by aperture.Aperture sieve plate easily blocks, and is not suitable for processing feed liquid that is dirty, tough and band solids; Macroporous plate is easy-to-leak liquid then, and the operating pressure of requirement is high, and mass-transfer efficiency is also lower.Sieve-plate tower has taken into account processing flux, purifying property and operation energy consumption preferably, but its structure compared with complicated, operating flexibility is little, installation requirement is high.

Different from industrial waste gas process, the air purifier of family expenses and similar applications is comparatively harsh for the requirement of gas phase drag.Because the factor such as noise, structure is to the restriction of blower fan, the gas phase drag of Household Air Purifier requires to be generally 100 ~ 200Pa, and pressure drop reaches 300 ~ 500Pa and is just difficult to enter practical application, and higher pressure drop cannot be implemented substantially.In bubble type purification techniques, gas needs through bubble level the pressure overcoming liquid level, and gas phase drag is very high, application of thus not yet succeeding in Household Air Purifier.

The sieve-board type bubble tower of prior art is generally gas-liquid counter current operation, and liquid distributor is located at top, and liquid sprays the column plate of the top downwards, the overflow of block-by-block column plate and under.The bubble level of gas-liquid contact only on column plate carries out, and substantially gas-liquid contact and mass transfer do not occur in the sieve aperture of column plate, aperture is generally 3 ~ 25mm.The technical scheme that the present embodiment provides, sieve plate forms by having certain thickness micro channel, and drop is carried secretly by gas from bottom to top, and following current through after the micro channel of sieve plate, then forms bubble level above sieve plate.Biphase gas and liquid flow mainly passes through with micro air bubble form through during micro channel, and the bubble level above column plate forms a large amount of bubble constantly break and upgrade further, thus has very large contact area and very high mass transfer efficiency.Although the aperture of each micro channel is very little, because pitch of holes is very little, on the contrary higher than the column plate of prior art, the pressure drop of whole column plate is not high for percent opening (on sieve plate the gross area of sieve aperture and the ratio of aperture area area).In addition, with prior art gas with continuous phase by compared with the sieve aperture of column plate, in the present invention, a large amount of bubble is by sieve aperture, and what continue sieve aperture with high flow velocities washes away, and it is dirty stifled to be not easy to produce fouling.

The present invention fully utilizes drop, liquid film and bubble and realizes gas-liquid contact, adopts process intensification technology, significantly improves purification efficiency.Compared with existing bubbling bed purification techniques, present invention uses the pore sieve plate with microchannel, gas-liquid mixture, by cut during the micro channel of sieve plate, extruding, mainly passes through with micro air bubble form, has very large contact area and very high mass transfer efficiency.And then the bubble diameter formed when gas-liquid mixture enters bubble level is also very little, has higher contact area and mass-transfer efficiency compared with common bubble tower.Meanwhile, a large amount of bubble carries out continuous erosion to sieve aperture at a high speed, and it is dirty stifled to be not easy to produce fouling.The present invention by the water storage of the elementary filter screen in gas channel, drip tray and absorbent ventilate layer, release water, form multiple high efficiency liquid phase circulation to increase liquid-gas ratio, not only enhance transmission and mass-transfer efficiency, and effectively reduce and control gas phase drag, make bubble type purification method be able to apply in Household Air Purifier.

Fig. 1 is the schematic cross sectional view of the micropore bubbling formula air purifier of the present embodiment.Micropore bubbling formula air purifier comprises housing 1, air inlet 2, absorbent ventilate layer 3, sieve plate 4, demist layer 5, air outlet 6, lift 13, liquid reducing device, blower fan 12 and water tank 15.Water tank 15 is positioned at housing bottom; Air inlet 2 is positioned at the position of more than lower housing portion, water tank level, from one or both sides or the surrounding air intake of housing; Demist layer 5 is positioned at the top of bubble level 9; Air outlet 6 is positioned at the top of housing.Housing 1 and air inlet 2, air outlet 6 form gas channel.Gas enters housing 1 from air inlet 2 under the effect of blower fan 12, and entrained liquids passes sieve plate 4 after forming gas-liquid mixture, forms bubble level 9 above sieve plate 4; Gas flows out from air outlet 6, and liquid flows down from liquid reducing device.

Sieve plate 4 is arranged in the position of more than the gas channel of housing, water tank level.Especially, as shown in Figure 2, sieve plate 4 is microchannel pore sieve plates, also claims honeycomb screen cloth, has certain altitude, spreads all over micro channel.Pore sieve plate is usually by sheet metal or fibre sheet material molding or sheet metal punch forming or ceramic post sintering is shaping or injection mo(u)lding.The structural parameters of sieve plate 4 are height 3 ~ 30mm, average pore size 0.8 ~ 8mm, percent opening 0.3 ~ 0.9.During air purifier for family expenses or similar applications, the preferred structure parameter of microchannel pore sieve plate is height 5 ~ 20mm, average pore size 1.5 ~ 3mm, and percent opening is 0.5 ~ 0.8.

Absorbent ventilate layer 3 is positioned at the below of sieve plate 4, is 0 ~ 50mm with the distance of sieve plate 4.Absorbent ventilate layer 3 is made up of foam metal material or hygroscopic fibre material, or accompanies the bilayer of absorbent material by centre or multi-layer silk screen is made.Absorbent ventilate layer is axially having a large amount of through hole, and thus gas phase drag is little; Water imbibition is strong, can storing liquid.When air-flow is through absorbent ventilate layer 3, the liquid it stored is produced by boasting, and carries formation gas-liquid mixture secretly and flows to sieve plate 4.This mode evokes water droplet with gas impact liquid level and forms water curtain or gas compared with the mode of bubbling liquid level, not only in gas-liquid mixture liquid carry over large, be evenly distributed, liquid-drop diameter is little, and gas-phase pressure drop is very little.

For making liquid be transported to absorbent ventilate layer quickly and evenly, the upper surface of absorbent ventilate layer 3 is provided with and leads to middle groove from surrounding.Or absorbent ventilate layer is pyramidal structure: when liquid flows into from periphery, low between the surrounding senior middle school of pyramidal structure, liquid flows to center from periphery; When liquid flows into from center, the low centre of surrounding of pyramidal structure is high, and liquid flows to periphery from center.In several ways can by Liquid transfer to described absorbent ventilate layer, such as: (1) by the lifting liquid in water tank 15, is transported to absorbent ventilate layer by lift 13; (2) liquid of bubble level 9 flows down from the liquid-droping groove 11 of liquid reducing device, is transported to absorbent ventilate layer; (3) from the downward leakage of the sieve aperture of sieve plate 4, absorbent ventilate layer is flow to.

Liquid reducing device is the passage of bubble level liquid backflow, the downflow weir being such as located at sieve plate periphery or center or the downspout be located on sieve plate.Liquid reducing device in the present embodiment comprises downflow weir 10, the liquid-droping groove 11 outside downflow weir 10 of being located at sieve plate 4 periphery.The upper end of downflow weir 10 has many V-notch, higher than sieve plate 10 ~ 80mm.Air inlet 2 is provided with deflector 7, and the inner side of deflector 7 upwards bends up, and makes the bottom of deflector form drip tray.Liquid-droping groove 11 is positioned at the top of deflector 7, and bottom and/or the bottom of liquid-droping groove 11 are provided with apopore.Liquid in liquid-droping groove 11 flows out from apopore, under air inlet 2 forms cascade pouring, then flows on the drip tray of deflector 7.

Between deflector 7 and liquid-droping groove 11, be provided with elementary filter screen 8, be hydrophily filter screen or water imbibition filter screen.Elementary filter screen 8 can carry out primary filter to air inlet, and the liquid in liquid-droping groove 11 pours on elementary filter screen 8, then flows on the drip tray of deflector 7 after flowing out.Liquid pours the surface of elementary filter screen 8, can be taken away by the air-flow of air inlet 2 quickly and efficiently; Accumulate in the liquid in drip tray, also splash by the gas shock of air inlet 2, form gas-liquid mixture.During the edge of the liquid level in drip tray higher than deflector 7, flow into after overflowing in the water tank 2 of bottom.

A kind of mechanism in lift water pump, screw lifting pipe, differential pressure riser or multiple combination.Water pump is conventional lifting liquid equipment; Screw lifting pipe is rotated by the screw rod in pipe to promote liquid, also can regard the one of water pump as; Differential pressure riser can not, by other power, by the pressure differential that sieve plate is upper and lower, by tubule, liquid higher-pressure region is from below risen to the low-pressure area of top, but the flow of Liquid transfer and pressure head be all less.Lift 13 in the present embodiment is screw lifting pipes, and screw rod directly or indirectly drives (also can by independent driven by motor) by the motor of blower fan.Lift is by the lifting liquid in water tank, and spray arrives the top of sieve plate 4, or from being upwards ejected into the bottom of sieve plate 4 between absorbent ventilate layer 3 and sieve plate 4, or be transported in liquid-droping groove 11.Described lift, by the lifting liquid in water tank, is transported to following one or more positions: (1) spray is to the top of described sieve plate 4; (2) bottom of sieve plate 4 is ejected into from the below of described sieve plate; (3) be transported in the liquid-droping groove 11 of described liquid reducing device.

Below the running status of micropore bubbling formula air purifier is described.

Air is under blower fan 12 acts on, and enter housing from air inlet 2, the elementary filter screen 8 successively above deflector 7, the absorbent ventilate layer 3 in gas channel, sieve plate 4, bubble level 9, demist layer 5, discharge from air outlet 6.Liquid in water tank 15 is promoted by screw lifting pipe 13, and spray to the top of sieve plate 4, and is ejected into bottom sieve plate from the below of sieve plate 4.

When liquid being sprayed the top of sieve plate 4, with the drop counter current contacting of spray after air leaves and bubbling area rises, enhance clean-up effect; When injecting liquid into the bottom of sieve plate 4, fine droplets is less easily entrained by passes through microchannel, spray feed liquid way under this plate can enlarge markedly by the liquid content in the gas-liquid mixture of microchannel, and reduce gas phase drag, the drop be not pulled away is fallen in absorbent ventilate layer 3.

More specifically, air enters housing from air inlet 2 under blower fan 12 acts on, during elementary filter screen 8 above deflector 7, the Hquid that the surface of elementary filter screen 8 is flowed down by liquid-droping groove 11, the solid contaminant in air is tackled by elementary filter screen 8, gaseous contaminant is absorbed by the liquid film on elementary filter screen 8 surface; Liquid in the liquid film on gas flow purging elementary filter screen 8 surface and drip tray, forms gas-liquid mixture and flows to absorbent ventilate layer 3.Solid-state and gaseous contaminant in air is tackled by absorbent ventilate layer 3 further and is absorbed, and is also blown afloat by the liquid that absorbent ventilate layer 3 stores, and is entrained with large quantity of fluid and is upward through sieve plate 4; Gas-liquid mixture is cut when passing through the micro channel of pore sieve plate 4, extruding, mainly passes through with micro air bubble form, and solid contaminant is absorbed by liquid film by liquid film parcel, gaseous contaminant.And then, gas-liquid mixture enters bubble level 9 in the form of bubbles through after sieve plate 4, bubble level 9 above sieve plate 4 produces a large amount of bubble and constantly breaks and upgrade, and greatly enhances mass transport process, all has very high purification efficiency to gaseous state, liquid state and solid contaminant.After bubble level 9, air continues upwards to flow, by discharging from air outlet 6 after demister 5.

Liquid phase circulation process is very complicated, not only different because of the specific embodiments of micropore bubbling formula air purifier, also relevant with the operating condition of air purifier, the pressure versus flow of air quantity and static pressure, lift, absorbent ventilate layer and the capacity of liquid-droping groove, the height of downflow weir all can affect the circulation of liquid phase.For ease of understanding, Fig. 3 gives the liquid phase circulation block diagram of micropore bubbling formula air purifier, explains various possible liquid phase circulation process below based on this figure, but also not all process is all present in the present embodiment shown in Fig. 1.First, the liquid in water tank is promoted by lift, the bubble level above sieve plate can be sprayed or be ejected into rise with air-flow bottom sieve plate or spray to absorbent ventilate layer or be transported to liquid-droping groove, or be transported to above-mentioned two or more positions.In addition, as previously mentioned, when the elementary filter screen of airflow passes, drip tray, absorbent ventilate layer, all partially liq wherein can be blown and spill, and carry secretly up, until arrive bubble level through sieve plate.The liquid flooding exceeding downflow weir in bubble level enters liquid-droping groove, and a part flows to absorbent ventilate layer from the apopore of liquid-droping groove bottom, and another part drenches from the apopore bottom liquid-droping groove and flow into drip tray behind the surface of elementary filter screen.When the liquid storage in drip tray is too much, after overflow, flow into water tank; When the liquid storage amount of absorbent ventilate layer is excessive, liquid also will instill water tank downwards.Especially, sieve plate generation leakage under certain operating, the liquid of bubble level spills from the hole of sieve plate, flows to absorbent ventilate layer downwards.It should be noted that, not for all embodiments and all operations condition, the liquid phase circulation path in figure all exists.Usually, rise to sieve plate or liquid-droping groove from water tank through lift, from bubble level overflow until the circulating path of water tank is the most basic liquid phase circulation, from absorbent ventilate layer with air-flow rise to sieve plate, from the circulating path of liquid-droping groove following current resorption water air-permeable layer be the most efficient liquid phase circulation.

The present invention generally adopts water as absorbing liquid.Distinguishingly, for specific vapor phase contaminants, if very little to the solubility of water, the absorbing liquid that suitable solubility is larger can be selected, the absorption removal capacity of air purifier to vapor phase contaminants can be strengthened.

The micropore bubbling formula air purifier compact conformation that the present embodiment provides, easy to use, gas phase drag is little, does not need to change consumptive material, has very high purification efficiency.
