Description

A kind of duster for cyclone-type boiler
Technical field
This utility model belongs to a kind of cleaner unit, is specifically related to a kind of duster for cyclone-type boiler.
Background technology
At present, in boiler industry, most of boiler dust removal equipment separation efficiency are low, and boiler expellant gas contains in a large number Dirt particle, Air Pollutant Emission is the most up to standard, causes the severe contamination of air and surrounding enviroment.Boiler dust removal equipment is general Expensive, strict law enforcement and the great dynamics of environmental administration is imposed a fine in addition, has had a strong impact on the normal production of enterprise, has made to enterprise Huge economic pressures and property loss are become.For solving an above-mentioned difficult problem, in the urgent need to a kind of efficient, reliable, economic boiler Cleaner.
The current common method of gas solid separation has: filter separation, gravity inertial separates, centrifugal sedimentation separates.Wherein, filtration point From method separation efficiency the highest, poor reliability;Gravity inertial separates needs bigger floor space, and separation efficiency is the most not High.In actual applications, using universal separating for centrifugal sedimentation, capital equipment is Cyclonic separating apparatus, and separation efficiency is only About 60%, treating capacity is the least, still can not meet the needs of actual production.
Utility model content
This utility model is contemplated to solve the problem that existing boiler dust remover efficiency of dust collection is the highest, the one proposed Duster for cyclone-type boiler.
This utility model realizes according to techniques below scheme.
A kind of duster for cyclone-type boiler, including housing, the upper end of housing connects upper cover, and lower end connects lower envelope Head, the lower end of low head connects dust collecting opening;It is provided with air inlet on the top of housing, is axially arranged with collecting pipe in enclosure interior, receive Collector forms air vent outside upwards reducing extends to housing;The isocon corresponding with air inlet it is provided with in described housing, point Flow tube is fixed on collecting pipe by the support set being arranged on collecting pipe, is additionally provided with kuppe in the bottom of collecting pipe;? Described lower housing portion is provided with baffle plate, and baffle plate connects downwards dust leg.
Connect on the outer surface of the 2/3 of described isocon and have a support set, air inlet and the isocon being not connected with support set The outer surface of 1/3 is relative.
Described collecting pipe upper end is diameter tube, and lower end is expansion tube.
Described upper cover is that ramp shaped is the most circular, and low head is taper;The bottom of collecting pipe is bell-mouth structure of air, and baffle plate is V-shaped structure.
The height of described housing is 5.8:1~6.2:1 with the ratio of internal diameter.
The internal diameter of described air inlet is 0.28:1~0.58:1 with the ratio of the internal diameter of housing.
The internal diameter of described dust collecting opening is 0.22:1~0.42:1 with the ratio of the internal diameter of housing.
This utility model obtains following beneficial effect.
This utility model effectively solves the problem that existing boiler dust remover efficiency of dust collection is the highest.So basis of design Utility model can effectively remove substantial amounts of dirt particle in boiler emission gas, reduces air and the dirt of surrounding enviroment Dye, also mitigates the production pressure of enterprise simultaneously, decreases economic loss.This utility model simple in construction, reliable, dedusting Efficiency, up to more than 90%, has broad application prospects.

Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in detail by embodiment.
As shown in Figure 1, 2, a kind of duster for cyclone-type boiler, including housing 1, the upper end of housing 1 connects upper cover, under End connection has low head, and the lower end of low head connects dust collecting opening 6;Circular air inlet 2 it is provided with, in housing 1 on the top of housing 1 Portion is axially arranged with collecting pipe 7, and collecting pipe 7 upwards reducing extends to housing 1 outer formation air vent 10;Arrange in described housing 1 Having the isocon 3 corresponding with air inlet 2, isocon 3 is fixed on collecting pipe 7 by the support set 9 being arranged on collecting pipe 7, It is additionally provided with kuppe 8 in the bottom of collecting pipe 7;Baffle plate 4, baffle plate 4 outer rim and housing 1 inwall it is provided with in described housing 1 bottom Between leave certain space, baffle plate 4 center has circular hole, and baffle plate 4 connects downwards dust leg 5.
Connect on the outer surface of the 2/3 of described isocon 3 and have support set 9, air inlet 2 and the shunting being not connected with support set 9 The outer surface of the 1/3 of pipe 3 is relative.Tangent with the cylindrical outer wall of the 1/3 of isocon 3 by the gas of air inlet 2, isocon 3 is Ceramic material.
Described collecting pipe 7 upper end is diameter tube, and lower end is expansion tube.The lower end of support set 9 is the variable-diameter joint of collecting pipe 7 Point.
Described upper cover is that ramp shaped is the most circular, and low head is taper;The bottom of collecting pipe 7 is bell-mouth structure of air, baffle plate 4 For v-shaped structure.
The height of described housing 1 is 5.8:1~6.2:1 with the ratio of internal diameter.
The internal diameter of described air inlet 2 is 0.28:1~0.58:1 with the ratio of the internal diameter of housing 1.
The internal diameter of described dust collecting opening 6 is 0.22:1~0.42:1 with the ratio of the internal diameter of housing 1.
Work process of the present utility model is: after boiler emission gas enters air inlet 2, and conventional tangential admission is changed into Half tangential entrance housing 1, portion gas collides with 1/3 column part of isocon 3, the gas of collision rift and another part gas Body mutually collides formation turbulent flow, and owing to gas temperature is higher, the chance making molecule in air-flow mutually clash into increases, and is formed relatively Bulky grain, downwards, under the influence of centrifugal force, bigger granule is got rid of to housing 1 inwall, drops to housing 1 end in tangential rotation The probability in portion increases, thus improves separation efficiency, owing to the effect of gravity drops to bottom housing 1, has separated so for the first time Become.The gas being rotated down, after kuppe 8, defines quick local mixing flow field, makes small contained in gas Grain collides to condense and merges, and forms sedimentation, completes second time gas solid separation.Rotate downward air-flow to turn to through baffle plate 4, due to The effect of centrifugal force, completes third time gas solid separation in collecting pipe 7.Gas after three gas solid separation passes through collecting pipe The air vent 10 on the top of 7 is discharged, and the granule collected collects bottom housing 1, is discharged outside housing 1 by dust collecting opening 6.
