The specific embodiment
As shown in Figure 1, cyclone dust collectors housing 1 and dividing plate 14,16 are divided into three parts with cyclone: front (left side) is the thick dirt pocket 2 of air inlet, and the centre is several whirlwind 4 in parallel, and back (right side) is that Purge gas is discharged chamber 17.The thick dirt pocket 2 of air inlet is settled a thick dedusting filter screen 3, and the big grit that filter screen 3 is dammed is collected by dust collecting box 10.Purge gas is discharged and also to be settled the thinner exhaust screen 18 of the thick dedusting filter screen of ratio 3 in the chamber 17, and the big grit that exhaust screen 18 dams is by 13 collections of dust collecting box.
Shown in Fig. 2,3.Whirlwind sub-component 4 is cylinders 23 of front end sealing, evenly opens four tangential slits 5 near on front end cylinder 23 walls, makes that air communication is out-of-date rotates along cylinder 23 tangential directions.For strengthening rotation, on tangential 5 right sides, slit guiding spiral 6 is installed, the direction of rotation of spiral 6 is with 5 air-flow direction of rotation are identical through the slit.The helical angle of spiral 6 is between 4 ° to 8 °.The sub-inwall of whirlwind on guiding spiral 6 the right shrinks gradually, and shrinking angle is 20 °-25 °, and low order end is a diffuser 8, is designed to be similar to the throat and the diffuser pipe of Venturi tube.The angle of flare of diffuser pipe is 6 °-7 °.Between cylinder 23 inwalls of throat's outer rim and whirlwind sub-component 4 space is arranged, the grit of Gong separating is current.Throat length is close with diffuser air inlet diameter.The grit of throwing whirlwind sub-component 4 outsides under centrifugal action under the gravity effect, is deposited in the dust collecting box 12 again.
If contain steam or other condensable vapors in the dusty gas, diffuser 8 throat's air velocities remain on the 50-80 meter per second, diffuser 8 exit flow speed 15-20 meter per seconds, lower the temperature greatly owing to air velocity becomes in throat, might make steam in air-flow, condense into the liquid pearl around the small micronic dust, can bonding one-tenth bulky grain between the small particle, gas flows to after Purge gas discharges chamber 17, stopped by exhaust screen in the chamber 18, in dust collecting box 13, collect.
As Fig. 4, shown in 5, cyclone dust collectors housing 1 and dividing plate 14,16 are divided into three parts with cyclone dust collectors: front (left side) is the thick dirt pocket 2 of air inlet, and the centre is several whirlwind sub-components 4 in parallel, and back (right side) is that Purge gas is discharged chamber 17.
The profile of whirlwind sub-component 4 is cylinders 23, the left end sealing, a central small hole 9 is opened in the centre, a little ash mouth 19 is opened at the edge, turning right is guiding spiral 6, evenly opens four tangential slits 5 on cylinder 23 walls, and another guiding spiral 20 is installed again on the right side in tangential slit 5,6 and 20 can couple together, and guiding spiral 6,20 and tangential slit 5 all make air-flow rotate in the same way.Right-hand member at guiding spiral 20 is installed diffuser 8, and dust is dished out from diffuser 8 outsides, and in diffuser purer air-flow with recovered part pressure.Wherein lead spiral 20 for to decide diameter spiral, and helical angle is 4-8 °.
Because action of centrifugal force, all can have rotation ash ring to form at about 5 two the roundlet tubes in tangential slit, for the right, the ash ring advances to diffuser 8 fronts, throw the outside of whirlwind sub-component 4 from diffuser 8 outer rims, under the gravity effect, be collected in the dust collecting box 13.Ash ring for the left side moves to the cylinder left bottom, will dish out from ash mouth 19.Part dust enters dust collecting box 10, also has a small amount of gas to follow dust to flow to whirlwind outside simultaneously.Because gas rotation will form low pressure near the central axis, whirlwind sub-component outside dusty gas flows to whirlwind sub-component 4 from bottom centre's aperture 9, and gas circulates the separation that helps minuteness particle inside and outside it.
As Fig. 6, shown in 7, this cyclone dust collectors are divided into three parts equally: two ends are respectively the thick dirt pocket 2 of air inlet and Purge gas is discharged chamber 17.The middle part is several whirlwind sub-components 4 in parallel, the series connection of two parts centrifugal force field before and after comprising, the front is the centrifugal force field of being set up by 5 tangential admissions and guiding spiral 6 from the slit, the back is the centrifugal force field that guide vane wheel 7 and another guiding spiral 20 are strengthened, these two centrifugal force fields all will be thrown the grit in the gas outward, collects respectively by two dust collecting boxs 11,12 by little ash mouthfuls 21,22, need separate with the dust of dividing plate 14 with sinking.Wherein the inclination angle of guide vane wheel 7 is 25-30 °, and the direction of rotation of blade is identical with the direction of rotation of guiding spiral 6.
The course of work of the present utility model is as follows: during work; dusty gas at first enters the thick dirt pocket 2 of air inlet; thick dedusting filter screen 3 is removed the coarse granule in the air-flow; coarse granule is collected in the dust collecting box 10 under the gravity effect; this has not only reduced dust content in 4 air inlets of whirlwind sub-component, and prevents the obstruction of coarse granule dust to tangential slit 5 and path thereof.Dusty gas becomes and rotatablely moves after tangential slit 5 enters whirlwind sub-component 4, and guiding spiral 6 has been strengthened this rotation.This centrifugal force field is thrown the outside of whirlwind sub-component 4 with most of dust, is collected under the gravity effect in the dust collecting box 11.Greatly reduce dust particle concentration in the gas like this.Guide vane wheel 7 is inserted among the centrifugal force field of tangential admission, after the gas that is purified by the centrifugal force field of tangential admission enters guide vane wheel 7, rotation is strengthened, there is guiding spiral 20 to strengthen centrifugal force again, in the gas by remaining less grit after the dedusting of tangential admission centrifugal force field, can be directed to the impeller centrifugal force field and throw the outside of whirlwind sub-component 4, under the gravity effect, be collected in the dust collecting box 12 through diffuser 8 outer rims.The gas that is purified by two centrifugal force fields flows through diffuser 8 in whirlwind sub-component 4, gas kinetic energy can be changed into the pressure energy.Because diffuser 8 is basically by venturi design, in its throat because the speed height, the gas cooling, if contain more rich steam or other easy condensing vapour in the gas, steam will occur in diffuser 8 throats condenses, promptly in the gas that purifies through the two-stage centrifugal field of force, with fine grained more is core, droplet congeals into, if collision is arranged between droplet, also can form larger particle, flow to Purge gas and discharge chamber 17, after being subjected to exhaust screen 18 obstructions, fall under gravity in the dust collecting box 13.
