Abstract
The utility model discloses a centrifugal guide vane of an efficient double delamination cyclone separator. The centrifugal guide vane comprises a body and an outer casing, wherein a plurality of spiral blades are arranged at intervals between the body and the outer casing; an air current channel is formed between every two adjacent spiral blades; the body and the outer casing are conical barrel with small upper parts and big lower parts; the taper angle of the body is larger than the taper angle of the outer casing; after adoption of a cyclone separator equipped with the centrifugal guide vane, a multibarrel cyclone dust extractor can treat high concentration flue gas with dust concentration of 30 g/m<3>, and the retention efficiency can reach 98%.
Description
Technical field
The utility model relates to a kind of centrifugal guide vane, particularly relates to a kind of centrifugal guide vane of efficient duplex layering cyclone separator, belongs to dedusting field of mechanical technique.
Background technology
The principle that is used for the cyclone separator in dedusting field is to utilize the High Rotation Speed of air-flow, make the grit that density is large be thrown toward wall under centrifugal action, and whereabouts reaches gas solid separation under Action of Gravity Field, get rid of the solid impurity in gas, purification, Purge gas, this is well known to those skilled in the art.Installing in the centrifugal guide vane of cyclone separator air inlet is its critical piece that produces cyclone effect.
The Chinese patent CN202460861U disclosed " compound layering cyclone and compound layering multi-tube dust cleaner thereof " of applicant's application has made the effort of the dust removing effects that improves the gas that high concentrate dust particle diameter difference is large, dust case hardness is high and temperature is high, but find through actual use, this technical scheme can meet general dedusting requirement, but its efficiency of dust collection is still not high, is difficult to be competent at some and requires harsh applicable situation.
Applicant is studied for the problems referred to above, find centrifugal guide vane structure unreasonable be one of reason that while causing high-temperature high concentration dedusting, efficiency is not high.And the centrifugal guide vane structure that aforementioned compound layering cyclone adopts is the multinomial patent of applying for as the applicant, the disclosed content such as CN202263655U, CN102513227A, comprise body, the appearance of body arranges multiple spiral blades, between the spiral blade evenly arranging, has formed the consistent gas channel of upper and lower flow area.The body of centrifugal guide vane can be single straight tube in addition, or is made up of the horn-like pipeline section of top straight length and bottom.This class centrifugal guide vane cannot meet the demands.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of centrifugal guide vane of efficient duplex layering cyclone separator, and after solving centrifugal guide vane and when for compound layering cyclone, first-stage centrifugal being separated, gas lacks constraint and the gas that makes to enter secondary centrifugation is easy to diffusion and then affect the problem of efficiency of dust collection.
The technical solution of the utility model is such: a kind of centrifugal guide vane of efficient duplex layering cyclone separator, comprise body and shell body, between described body and shell body, evenly interval arranges some spiral helicine blades, between described adjacent spiral blade, form gas channel, described body and shell body are all up-small and down-big frustum of a cone cylinders, and the cone angle of described body is greater than the cone angle of shell body.
Further, the lower end of described body is provided with forces refluence skirt, and described pressure refluence skirt is the straight tube being extended downward vertically by body lower end.
Further, the outside horizontal-extending in the upper end of described shell body forms annular cover plate.
Preferably, described blade quantity is 5～12.
In a specific embodiment of the present utility model, described blade is tile.
Preferably, described blade quantity is 8～10.
Technical scheme provided by the utility model has been complied with the centrifugal motion track of air-flow, can provide more efficiently the effect of centrifugal force to carry out dust separation.Can effectively air-flow be directed to secondary centrifugal guide vane, to carry out secondary cyclone separation.The cyclone separator that is equipped with this structure centrifugal guide vane is brought into play desirable can effectively improving the centrifugation of soot dust granule on multicyclone, makes multicyclone can process dust-laden 30g/m
3high-concentration fume, and efficiency of dust collection is up to 98%.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Refer to Fig. 1, Fig. 2 and Fig. 3, the centrifugal guide vane of the efficient duplex layering cyclone separator of present embodiment has comprised a up-small and down-big frustum of a cone cylinder body 1, this body 1 is in centrifugal guide vane inner side, the outside of centrifugal guide vane is the up-small and down-big frustum of a cone cylinder of another one, is referred to as shell body 2.The corresponding circular cone cone angle of frustum of a cone cylinder of body 1 is greater than the corresponding circular cone cone angle of frustum of a cone cylinder of shell body 2, and the width that forms thus the ring section of passage between body 1 and shell body 2 is axially from top to bottom reducing gradually.The even interval of spiral blade 3 of 5～12 is arranged between body 1 and shell body 2 and forms in passage, and this passage is divided into multiple gas channels.Flue gas enters the lower space of multicyclone, enters vertically this centrifugal guide vane, and up-small and down-big frustum of a cone cylinder body 1 has been complied with the centrifugal motion track of air-flow, and dust separation is carried out in the effect of science and engineering centrifugal force more efficiently.And the passage of the special shape of formation increases the low-pressure area space after flue gas eddy flow between body 1 and shell body 2.The straight tube being extended downward vertically by body 1 lower end becomes forces refluence skirt 4.The cyclonic air flow of forcing arranging of refluence skirt 4 can effectively suppress after one-level separates spreads to cyclone separator center in the time entering secondary centrifugal guide vane.It can effectively be directed at air-flow secondary centrifugal guide vane, to carry out secondary cyclone separation.The outside horizontal-extending in the upper end of shell body 2 forms annular cover plate 5 so that with existing cyclone separator shell combination.
Another is the change to blade 3 shapes as further improved embodiment, be that in previous embodiment, spiral blade 3 is used a watt shape blade 3 instead, watt shape blade 3 deciles of 8～10 are arranged between body 1 and shell body 2, the cross section curve of watt shape blade 3 is generally parabola, the plurality of blade 3 is still arranged in the outer surface of body 1 with spiral form, the tangent line at the parabolical upper extreme point of multiple blades 3 place has just in time formed the helix of body 1 outer surface.
