Using the beneficial effect of the device for mitigating exchanging pipe of boiler by waste abrasion of above-mentioned technical proposal：Blast pipe is by dust-laden
Gas is introduced to enclosure interior, and the helical wind-guiding groove set by conical shell outer wall has wind effect, and dusty gas tangentially enters
Enter after housing, gas carries out cyclonic separation, and dusty gas is during high speed centrifugation rotates, and particulate matter is got rid of to the side of housing
Edge simultaneously gradually sinks down into dust collecting opening；Because the wind speed of recuperated gas has unstability, therefore when wind energy is reduced, gas enters
Centrifugal effect after housing is not good, therefore using the design of conical shell, cutting under upper between conical shell and housing
Identity distance ensures still there is higher centrifugal speed after wind energy reduction by space transfiguration, solved because of wind energy from being gradually reduced
Loss and cause centrifugal speed to reduce, influence gas in particulate matter separating effect the problem of, it is ensured that particulate matter in gas
Efficiently separate；Clean gas during cyclonic separation after preliminary filtering is located at the middle part of housing, due in dust collecting opening
Provided with the lid for closing the end, gas is just moved up along the air inlet spiral of tubular filter bag, the mistake that gas spiral is moved up
Cheng Zhong, filtering of the portion gas through tubular filter bag enters to the space that conical shell inwall filters bag formation with tubular, so that
The cleanliness factor of gas is further lifted, and the gas after tubular filtering bag filtration rises through the air-out located at conical shell upper end
Pipe is spread out of, available in production to the demand of high temperature clean gas；Remaining most of gas is directly discharged along tubular filter bag
Enter waste heat boiler afterwards, these gases effectively prevent heat exchanger tube because of the hard in recuperated gas due to have passed through centrifugation
Particle and cause the abrasion to tube wall, it is ensured that the normal operation of equipment, reduce equipment operation maintenance cost.
Preferably, it is contemplated that the stability of structure, the conical shell is metal material.
Preferably, the intensity of housing and the consumption of material are considered, the thickness of shell is not less than 5mm.
Preferably, it is contemplated that the convenient replacing to tubular filter bag, the conical shell is filtered with the tubular
Detachable connection between bag.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：Housing 1；Dust collecting opening 2；Lid 3；Blast pipe 4；Conical shell 5；Helical wind-guiding groove 51；Tubular filter bag 6；
Air inlet 61；Discharge pipe 7.
Embodiment
Technical solutions of the utility model are further illustrated with reference to the accompanying drawings and examples：
As shown in figure 1, a kind of device for mitigating exchanging pipe of boiler by waste abrasion, includes the housing 1 of cylindrical shape, housing 1 is adopted
It is welded with steel plate bending, thickness selection is 6mm, the lower end of housing is provided with the diminishing dust collecting opening 2 of bore, dust collecting opening 2
Dismountable lid 3 is provided with, herein from flange method, is mainly used in ash discharge, the tangential direction of the top of housing 1 along side wall
The blast pipe 4 inside air inducing to housing 1 is welded with, the upper end of housing 1 is closed by end cap, is welded with what is run through on end cap
Double-layer barrel structure, the axis of double-layer barrel structure is consistent with the axis of housing 1, and double-layer barrel structure includes the cone of metal material
Shape cylinder 5 and tubular filter bag 6, the small-caliber end of conical shell 5 is upward and housing 1 is stretched out at the end, and tubular filter bag 6 is sheathed on
In conical shell 5, the upper and lower side of conical shell 5 closes the fixation for being connected and realizing the two position, cone between tubular filter bag 6
Cavity is formed between shape cylinder 5 and tubular filter bag 6, the outer wall of conical shell 5 is provided with helical wind-guiding groove 51, conical shell 5
Upper end is provided with discharge pipe 7, and the gas that discharge pipe 7 is obtained have passed through 2 filterings, very totally, thus available in producing for
The demand of high temperature clean gas, the lower end of tubular filter bag 6 is air inlet 61, and the upper end of tubular filter bag 6 is connected to waste heat pot
Stove, the gas into waste heat boiler have passed through and once be centrifuged at a high speed, therefore can mitigate the abrasion of exchanging pipe of boiler by waste, separately
The outer replacing for convenience of to tubular filter bag 6, detachable connection between conical shell 5 and tubular filter bag 6.
The technical solution of the utility model so works：Dusty gas is introduced to inside housing 1 by blast pipe 4, cone
Helical wind-guiding groove 51 set by the outer wall of shape cylinder 5 has wind effect, and dusty gas enters after housing 1, and gas carries out whirlwind
Separation, dusty gas is during high speed centrifugation rotates, and particulate matter gets rid of to the edge of housing 1 and gradually sinks down into dust collecting opening 2；
Because recuperated gas wind speed can gradually be reduced because of friction, to compensate this wind speed loss, therefore using the design of conical shell 5,
Cross-sectional distance between conical shell 5 and housing 1 under upper is gradually reduced, and is ensured by space transfiguration after wind energy reduction still
With centrifugal speed, solve because wind loss of energy and caused by centrifugal speed reduce, influence gas in particulate matter separating effect
The problem of, it is ensured that particulate matter efficiently separates in gas；Clean gas position during cyclonic separation after preliminary filtering
In the middle part of housing 1, because dust collecting opening 2 is provided with the lid 3 for being used for closing the end, gas just entering along tubular filter bag 6
Air port spiral is moved up, during gas spiral is moved up, the filtering through tubular filter bag 6, is discharged into the inwall of conical shell 5 and cylinder
The cleanliness factor of gas between the outer wall of shape filter bag 6 is further lifted, and the gas after being filtered through tubular filter bag 6 rises through setting
Discharge pipe 7 in the upper end of conical shell 5 is drawn, other gases for not passing through tubular filter bag 6, into waste heat boiler, due to this
Portion gas, which have passed through, to be centrifuged at a high speed, and most of particle is particularly bigger particle and is all disposed of, therefore effectively keeps away
Exempted from heat exchanger tube because the hard particles in recuperated gas and caused by abrasion to tube wall, it is ensured that the normal operation of equipment, reduction
Equipment operation maintenance cost.
