Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail and is illustrated.
Fig. 1 is the schematic front view of the utility model active spiral cyclone dust collector.As shown in Figure 1, this active spiral cyclone dust collector comprises package 1, be provided with from top to bottom in package 1 be connected successively chimney fan 2, on air duct 3 and conically shaped 4, wherein goes up air duct 3 and be provided with air inlet 5, and conically shaped 4 is coaxial with upper air duct 3.Outside package 1, be provided with the fluid reservoir 8 of the belt pulley 6 for driving conically shaped 4 to rotate and motor, the flue-dust retainer 7 be communicated with the lower end of conically shaped 4 and this flue-dust retainer 7 accommodating, wherein the lower end of flue-dust retainer 7 is communicated with fluid reservoir 8 and is immersed in the liquid in fluid reservoir 8.As shown in Figure 1, between package 1 and conically shaped 4, define the annular passage for wind-guiding.
Active spiral cyclone dust collector of the present utility model also comprises and is located at blower fan 9 outside package 1 and spray system 10, and wherein, the air outlet of blower fan 9 is communicated with the air inlet 5 of upper air duct 3, as shown in Figure 2.It is inner that the spray head of spray system 10 is arranged on air duct 3, and the liquid in fluid reservoir 8 can be delivered to the top of conically shaped 4 by spray system 10 via pipeline by pump, ejecting liquid thus form liquid film at the inner surface of conically shaped 4.Fig. 1 shows the concrete structure that wherein package air intake connects.Blower fan 9 can be cross flow fan or common blower fan.
As shown in Figure 3, the inwall of conically shaped 4 is also provided with the helicla flute of Length discrepancy, varying pitch.
After dust-contained airflow enters upper air duct 3 by blower fan 9 by air inlet 5; form the air-flow under screw; air-flow is at the inner surface through conically shaped 4; due to the wall effect of the conically shaped 4 of rotation, near its inner surface, flow field changes, and grit is run out of steam fast and stays wall; conically shaped 4 inner surface with liquid film then more easily absorbs the grit in air-flow; under the active rotation effect of conically shaped 4, grit imports in the helicla flute in conically shaped 4 cone, flows in flue-dust retainer 7 further.
The utility model is according to the fastest decline curve experiment under gravity, and the helix on the conically shaped inwall adopted is variable-pitch propeller line.
The utility model is equipped with sealing device between conically shaped 4 and upper air duct 3, flue-dust retainer 7, and thus dust-contained airflow can not flow out from these connecting portions.Flue-dust retainer 7 is connected with fluid reservoir 8, and due to the iris action of liquid in fluid reservoir 8, thus air-flow also can not be overflowed from flue-dust retainer 7 or flow out.Therefore, the air-flow being predominantly absorbed grit can only flow out from centre to the upper end of chimney fan 2, thus reaches the object of pure air.
Spray system 10 in the utility model is to ensure that conically shaped inwall is arranged with liquid film, can spray mist film or solution as required.And, when the inwall of conically shaped has more attachments, then strengthen spouting liquid, form the interior surface of fluid column flush clean deduster.Therefore, the liquid that the nozzle of spray system 10 sprays can spray or be washed into the major part position of conically shaped 4.
Conically shaped 4 can independently rotate, and the rotating speed of conically shaped 4 can change rotating speed or rotation direction according to dedusting Particle size requirements.By analysis and experiment, if independent conically shaped 4 speed of rotating is too high, will upset interior flow field, therefore setting velocity of rotation is less than 240 revs/min; The cone length of conically shaped 4 is 1.5 ~ 2.5 times of outer barrel diameter, the inwall of conically shaped 4 is provided with the variable-pitch auger groove of Length discrepancy, its Changing Pattern is: conically shaped major part spiral fluted helical angle is 5 ~ 20 degree, conically shaped microcephaly spiral fluted helical angle at least 2 times, to major part spiral fluted helical angle, changes in proportion.And, the head number of helix is even number (such as, the spiral the end of a thread number in Fig. 3 is 6), wherein has the length of the helix of a half a head number to be 1/2 ~ 2/3 of conically shaped cone height, spiral starting point is the stub end from conically shaped, the better dust removal effect under this geometrical condition.
Upper air duct 3 of the present utility model adopts symmetric double entrance structure, namely cylinder 3 of being in the wind is provided with symmetrical two air inlets 5, be conducive to the stable of inner wind field like this, air inlet 5 can adopt airduct or package to connect, the blower fan of thin-and-long air outlet easy to use, can certainly adopt separately independently air intake method.
According to the grit characteristic in dust-contained airflow, the rotating speed of conically shaped 4 can change rotating speed or rotation direction according to dedusting Particle size requirements, helicla flute on conically shaped 4 and liquid wash away location matches, helical angle and and air inlet angle automatching, to make the whole inwall of conically shaped 4 can with liquid film.
As an instantiation, be the cyclone dust collectors of 148mm for upper air duct diameter, the cross flow fan that employing diameter is 60mm, long 300mm, rotating speed are 1500 revs/min, the cyclone dust collectors relevant parameter determined, conically shaped section sets is non rotating or with 60 revs/min of rotations, carries out CFD emulation to dust-contained airflow, adopts Reynolds pressure model (RSM), arranging DPM particle is the grains of sand, diameter normal distribution centered by 0.25 micron.Result of calculation shows, the air outlet velocity average out to 5.32m/s of cross flow fan, and when conically shaped non rotating, dust removing effects is identical with existing cyclone dust collectors, to the granule capturing rate being less than 0.5 micron only about 5%; And when conically shaped rotates, to more than 0.15 micron grit, arresting efficiency is more than 50%, when arranging wall for the trapping of band liquid film, it can more than 90% to more than 0.15 micron grit capture rate.
Fig. 4 is the schematic front view of the further modified node method of the utility model active spiral cyclone dust collector, wherein adopts and is separated airduct air intake.As shown in Figure 4, air channel is here spiral duct.Dust-contained airflow enters spiral duct by air inlet, is more conducive to forming spiral air flow in conically shaped.
It should be noted that, active spiral cyclone dust collector entirety of the present utility model can be erect or slant setting, is not limited to the erectility shown in Fig. 1 and Fig. 4.Also different spray solution can be adopted, to remove the predetermined substance in air.
Visible, active spiral cyclone dust collector of the present utility model, change the dust-contained airflow that original cyclone dust collectors need higher tangential velocity, spiral rotating motion is become with rectilinear motion from air inlet, by grit run out of steam decline operation principle, local flow field is changed by the cone rotated, active collection, " connect " the grit in air-flow, reduce the rate request of dust-contained airflow, the grit of stop motion is made to enter flue-dust retainer by helicla flute, avoid secondary gray back, effectively can remove the grit that air is greater than 0.15 micron, especially the PM2.5 particulate be detrimental to health, improve the effect of purification of air, and efficiency of dust collection is high, air-flow dust-laden particle diameter, dust content adaptive surface is wider.
Although be described in detail preferred embodiment of the present utility model and illustrate, the utility model is not limited thereto.It should be known that those skilled in the art can carry out numerous modifications and variations under the condition not deviating from spirit of the present utility model and principle, and do not depart from its protection domain of the present utility model limited by claims.
