Description
Technical field
The present invention relates to a kind of dry ash dust arrester installation, especially a kind of cyclone separator group of efficiently gathering dust.
Background technology
At present, in the dry ash field of gathering dust, generally use cyclone separator, because the advantage such as that cyclone separator has is simple in structure, easy to maintenance, use cost is low, but the cyclone separator dust-collecting efficiency is lower.Cyclone separator is as elementary dust collection device, and in order to improve dust-collecting efficiency, its rear end need to connect electrostatic precipitator or sack cleaner usually, and electrostatic precipitator and sack cleaner complex structure, troublesome maintenance, use cost are high.When carrying out large flow dedusting, generally adopt many multiple cyclone in parallel forms, so not only have higher dust-collecting efficiency than single large diameter cyclone separator, and can also reduce the overall installation height of equipment.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the cyclone separator group of efficiently gathering dust that a kind of dust-collecting efficiency is high, the common thin grey secondary entrainment phenomena that occurs of the ash discharging hole of cyclone separator is eliminated is provided.
according to technical scheme provided by the invention, the described cyclone separator group of efficiently gathering dust, comprise prime cyclone separator and rear class cyclone separator, some prime cyclone separators are and are connected in parallel, the blast pipe of the blast pipe of prime cyclone separator and rear class cyclone separator is connected in parallel into pump-line, ash hole at every prime cyclone separator all is connected with the prime flue-dust retainer, the ash hole of rear class cyclone separator is connected with the rear class flue-dust retainer, be fixed with the prime installing rack in the prime flue-dust retainer, be installed with the conical blast cap of prime on the prime installing rack, the vertex of a cone of the conical blast cap of prime up, has the gap between the cone feather edge of the conical blast cap of prime and prime flue-dust retainer inwall, be connected in parallel to the air inlet pipe that coordinates with the number of units of prime cyclone separator on the air inlet of described rear class cyclone separator, the inlet end of described air inlet pipe is arranged in the hypomere divergent-cone wall bottom of corresponding prime cyclone separator, be fixed with the rear class installing rack in the rear class flue-dust retainer, be installed with the conical blast cap of rear class on the rear class installing rack, the vertex of a cone of the conical blast cap of rear class has the gap between the cone feather edge of the conical blast cap of rear class and rear class flue-dust retainer inwall up.
Described conical blast cap is coaxial setting with the hypomere divergent-cone wall of prime cyclone separator.The size of described prime cyclone separator is greater than the size of rear class cyclone separator.
The phenomenon that the common thin grey secondary that occurs of the ash discharging hole of the prime cyclone separator in the present invention entrainments is eliminated, and greatly reduces by the powder containing quantity in the weary gas of rear class cyclone separator middle part central tube discharge; Cyclone separator group efficient of the present invention can exceed 3 ~ 5 percentage points than conventional cyclone separator, and its dust-collecting efficiency is guaranteed more than 95%, can finely satisfy the safe operation requirement of high-efficiency abrasion-proof blower fan.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
as shown in the figure: this cyclone separator group of efficiently gathering dust, comprise prime cyclone separator 1 and rear class cyclone separator 2, some prime cyclone separators 1 are and are connected in parallel, the blast pipe of the blast pipe of prime cyclone separator 1 and rear class cyclone separator 2 is connected in parallel into pump-line 3, ash hole at every prime cyclone separator 1 all is connected with prime flue-dust retainer 4, the ash hole of rear class cyclone separator 2 is connected with rear class flue-dust retainer 9, be fixed with prime installing rack 5 in prime flue-dust retainer 4, be installed with the conical blast cap 6 of prime on prime installing rack 5, the vertex of a cone of the conical blast cap 6 of prime up, has the gap between the cone feather edge of the conical blast cap 6 of prime and prime flue-dust retainer 4 inwalls, be connected in parallel to the air inlet pipe 7 that coordinates with the number of units of prime cyclone separator 1 on the air inlet of described rear class cyclone separator 2, the inlet end of described air inlet pipe 7 is arranged in the hypomere divergent-cone wall bottom of corresponding prime cyclone separator 1, be fixed with rear class installing rack 10 in rear class flue-dust retainer 9, be installed with the conical blast cap 8 of rear class on rear class installing rack 10, the vertex of a cone of the conical blast cap 8 of rear class has the gap between the cone feather edge of the conical blast cap 8 of rear class and rear class flue-dust retainer 9 inwalls up.
Described conical blast cap 6 is coaxial setting with the hypomere divergent-cone wall of prime cyclone separator 1.The size of described prime cyclone separator 1 is greater than the size of rear class cyclone separator 2.
The thin grey air-flow that contains from grader outlet tangentially enters prime cyclone separator 1, produces strongly to rotatablely move, and thin ash particle is got rid of to the wall of prime cyclone separator 1 under the effect of centrifugal force, slides to ash discharging hole under then under action of gravitation to discharge downwards.In the process that flow rotation moves down, a part of air-flow joins in updraft on the line of separator axle center gradually, and another part air-flow is accompanied by the separated thin ash that gets off to be continued to rotate downwards to enter into prime flue-dust retainer 4.Subsequently, most of thin ash enters thin grey storehouse through lock gas discharge valve device by prime flue-dust retainer 4 is rear downwards by action of gravitation.The air-flow of following thin ash to leave prime cyclone separator 1 from prime cyclone separator 1 bottom accounts for the certain proportion of general gas flow, if this part air-flow does not guide, they can turn back in prime cyclone separator 1 under the effect of negative pressure at last again, and carry a large amount of thin ashes, thereby greatly reduce actual efficiency.
In the present invention, by the conical blast cap 6 of the prime in prime cyclone separator 1 with its Base top contact from prime flue-dust retainer 4, again add in the air-flow of rear class cyclone separator 2, utilize the blast pipe of the blast pipe of prime cyclone separator 1 and rear class cyclone separator 2 be connected in parallel into pump-line 3 negative pressure extract out and process laggard inlet/outlet flues through rear class cyclone separator 2.
For reducing overall height, utilize two prime cyclone separator 1 structures of backrest type, thin grey air-flow enters two prime cyclone separators 1 at cyclone inlet punishment two-way, prime cyclone separator 1 diameter relative decrease, have the larger single separator of diameter group and have higher separative efficiency under identical entrance velocity, be to reduce, all be connected with prime flue-dust retainer 4 at the ash hole of every prime cyclone separator 1, the ash hole of rear class cyclone separator 2 is connected with rear class flue-dust retainer 9.
By such cyclone separator group, the phenomenon that the common thin grey secondary that occurs of the ash discharging hole of prime cyclone separator 1 entrainments is eliminated, greatly reduce by the powder containing quantity in the weary gas of rear class cyclone separator 2 middle part central tubes discharges, cyclone separator group efficient of the present invention can exceed 3 ~ 5 percentage points than conventional cyclone separator, its dust-collecting efficiency is guaranteed more than 95%, can finely satisfy the safe operation requirement of high-efficiency abrasion-proof blower fan.
