The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figures 1 and 2, the utility model preferred embodiment proposes a kind of deduster, comprising: helical duct 1, water fog generator 4, fan 5, water purification dish 3 and sewage dish 2, wherein:
Described helical duct 1 integral body is scroll casing shape, and it has entrance 11, discharge outlet 12 and exhaust outlet 13, and discharge outlet 12 is arranged on the center of helical duct 1 bottom, and exhaust outlet 13 is arranged on the center at the top of described helical duct 1.
Described water fog generator 4 is arranged on entrance 11 ends of helical duct 1, with described helical duct 1, is communicated with, in described helical duct 1, spraying into water smoke.
Described water purification dish 3 is arranged on the below of described helical duct 1, with described water fog generator 4, is connected, and is used to described water fog generator 4 that water purification is provided;
Described fan 5 is arranged on outside the entrance 11 of described helical duct 1, for making helical duct 1 outer air enter described helical duct 1, with described water smoke, mixes, at the interior formation swirling eddy of helical duct 1; Swirling eddy, in helical duct 1 is interior, is isolated the drop that is bonded with dirt in air under the effect of centrifugal force, from discharge outlet 12, discharges; Removing the swirling eddy of dust drop discharges from the exhaust outlet 13 at described helical duct 1 top.
Particularly, the present embodiment deduster is specifically humidifying dust collector, and it has applied water mist dust-removing principle and cyclone dust removal principle, except can removing general dust, can also remove the PM2.5 particulate that the prior art commonsense method can't be removed.
Wherein, the water mist dust-removing principle is: when water fog particle is close with the dust granules diameter, and the adsorption filtration of formation, the probability maximum of condensing.Therefore as long as generation adsorbs with it it with the sizable micron order water fog particle of dust granules, bonding, assemble increase sedimentation under the effect of self gravitation mutually, thereby reach the purpose of depositing dust.Produce anion when water smoke forms, cation anions in water smoke a large amount of in dust are combined, thus depositing dust rapidly.In addition, water smoke contacts with dry dust, has increased the humidity of air, absorbs a large amount of air latent heat simultaneously, plays good cooling effect.The water fog particle size that the water mist dust fall technology produces mainly concentrates on 1-50 micron (μ m) left and right, and dust below 50 microns is had to extremely strong dust removing effects, thereby in the harm of pollution source control respirable dust particle below 5 microns to human body.
The cyclone dust removal principle is: cyclone dust removal is the centrifugal force that utilizes the dust-contained airflow of rotation to produce, the process that particulate pollutant is separated from gas.When dust-contained airflow enters cyclone dust collectors by air inlet pipe, air-flow becomes circular motion by rectilinear motion.Dusty gas produces centrifugal force in rotary course, and the particle that density is greater than to gas gets rid of to wall, once particle contacts with wall, just loses inertia force and falls along wall by the momentum of entrance 11 speed and downward gravity, and then discharge.Under normal operational conditions, the centrifugal force of particle is 5-2500 times of gravity, and great majority, with removing the particle more than 0.3 micron, have the efficiency of dust collection of 80-85% to the particle more than 3 microns.
Above-mentioned water mist dust-removing principle applied by the present embodiment deduster and the cyclone dust removal principle realizes the dust removal of (comprising the PM2.5 particulate).
More specifically, as shown in Figure 1, produce water smoke by water fog generator 4 and enter helical duct 1.
After impure air enters helical duct 1 by deduster entrance 11, water smoke mixes with the air that contains dust (comprising the PM2.5 particulate), and dust mutually bonds under the effect of water smoke drop, forms larger particle.
With the mixed airflow of particle during by helical duct 1, be subject to the guide functions of helical duct 1 and produce strong rotation, air-flow enters twist along passage, drop/mixture that density is large is thrown toward vias inner walls under centrifugal action, and under Action of Gravity Field, sewage dish 2 the insides that fall to collecting deduster by discharge outlet 12 along inwall, dust is thrown toward vias inner walls, will be adsorbed by the sewage of inwall, along with sewage together along inwall whereabouts flow pass discharge outlet 12 to deduster the bottom sewage dish 2.The air-flow of the humidity of rotation, is discharged by the exhaust outlet 13 of helical duct 1 top center to center flow in the interior contraction of helical duct 1.
Therefore, all dust that mix with water all can be clung by water, focus in sewage dish 2, and can not produce secondary dissipation, reach thus the purpose purified air.
In addition, can also connect dehumidifier at the exhaust outlet 13 of deduster helical duct 1, the malaria of discharge can be removed moisture by dehumidifier, obtains the air of dried and clean.Can play the effect of humidifier when closing dehumidification function.
In dust removal process, above-mentioned water fog generator 4 is for generation of 1-50 micron left and right water smoke.Water smoke is blended in the air of helical duct 1, water smoke is to be formed by countless drops, surface area while with the contact area rate of air, being contained in water pond is large without several times, when drop moves in air, can well adsorb dust, form the mixture of water smoke dust, density volume and the water smoke of mixture are more approaching, radius than dust is larger, most of 10 μ m that surpass.If water smoke is fully mixed with air, can make most dust be adsorbed by water smoke.Wherein, particle is larger, and the centrifugal separating effect in helical duct 1 is better, and removal effect is more obvious.
Said fans 5 makes the air of deduster outside enter helical duct 1, and drives the water smoke in helical duct 1, makes mixture rotating separation in helical duct 1.
The characteristics of above-mentioned helical duct 1 are that entrance 11 is large, go out youngly, and entrance 11 sectional areas of helical duct 1 are greater than the sectional area of helical duct 1 exhaust outlet 13, and from entrance 11 to exhaust outlet, 13 passages present the helical structure of continuous contraction to helical duct 1.Air can form swirling eddy helical duct 1 is interior, and, the closer to exhaust outlet 13, radius of turn is less; The closer to exhaust outlet 13, sectional area is less, and the speed that causes air-flow to pass through is faster.
The present embodiment is used the dedusting of cyclone dust removal principle, is to have adopted the centrifugation principle in essence.While rotating, suffered power is all to be produced by air push to particulate in helical duct 1 (mixture that comprises water smoke/dust/water smoke dust, abbreviation particulate), and the stressed decomposition of particulate as shown in Figure 3.Wherein, the tangential stressed f1 of direction of rotation increases the speed V of particulate; F2 provides centripetal force for particulate.In the radial direction, particulate is subject to the resistance of centrifugal force and air.Owing to can not being relative static relation between particulate and air, so there are sliding friction in particulate and air, air be force of sliding friction F to the resistance of particulate
friction.F
frictionwith F
centrifugalopposite direction, both action effects are cancelled out each other.
At centrifugal force F
centrifugaleffect under, the acceleration of particulate is a
centrifugal=V^2/R; I.e. particle size no matter, the centrifugal force acceleration of particulate is all identical.
That affect the separation of particles effect is force of sliding friction F
friction.By formula 1:a
friction=3k/(r * ρ) can know: the particulate that volume is larger, a
frictionjust less.
Along with the particulate volume increases, a
centrifugalconstant, and a
frictionreduce, particulate is at a
centrifugalwith a
frictioneffect more easily separated from the gas.
As the above analysis, in the cyclone dust removal process, particulate is larger, and separating effect is more obvious.Therefore, in order to strengthen the separating effect of cyclone dust removal, by water fog generator 4, produce water smoke, utilize water mist dust fall, can increase the dust volume, make the effect of cyclone dust removal more obvious.
It should be noted that, in the such scheme of the present embodiment, the shape of helical duct 1 can be not limited to above-mentioned a kind of, but can design as required different shapes, the mounting structure of helical duct 1 also relatively Fig. 1 change to some extent, but based on dust-cleaning principle constant, still: drop is mixed with dust, in helical duct 1, because centrifugation principle and passage collide, stick on conduit wall; Dust because centrifugation principle and passage collide, sticks on conduit wall in helical duct 1.
The present embodiment, by such scheme, is effectively removed dirt in air (comprising the PM2.5 particulate), has improved air purity, and can regulate to a certain extent the humidity in room, and its structure is also simple.
In actual applications, above-mentioned deduster can be applied in the indoor dedusting of air-conditioner, specifically this deduster can be arranged on air-conditioner outdoor unit or air conditioner room unit, for to entering indoor outdoor air, carrying out dedusting; Perhaps, described deduster is arranged on indoor, for the air to indoor, carries out dedusting.
In addition, the utility model also proposes a kind of air-conditioner, comprises the described deduster of above-described embodiment, does not repeat them here.
The utility model embodiment deduster and air-conditioner, spray into water smoke by water fog generator 4 in helical duct 1, and by fan 5, make the outer air of helical duct 1 enter described helical duct 1 to mix with described water smoke, airborne dust is combined with drop, mist is at the interior formation swirling eddy of helical duct 1, under the effect of centrifugal force, the drop that is bonded with dust is thrown toward vias inner walls, and under Action of Gravity Field, the sewage dish 2 of bottom along inwall whereabouts flow pass discharge outlet 12 to deduster, the air-flow of rotation shrinks to center flow in passage, through the center of passage top vent 13, discharge again, thus, effectively remove dirt in air (comprising the PM2.5 particulate), improved air purity, and the humidity that can regulate to a certain extent room, its structure is also simple.
Above are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present utility model.
