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,, generally use cyclone separator in the dry ash field of gathering dust, because 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 connect electrostatic precipitator or sack cleaner usually, electrostatic precipitator and sack cleaner complex structure, troublesome maintenance, use cost height.When carrying out big flow dedusting, generally adopt many multiple cyclone in parallel forms, so not only have higher dust-collecting efficiency, and can also reduce the overall installation height of equipment than single large diameter cyclone separator.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists 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 takes place of ash discharging hole of cyclone separator is eliminated is provided.
According to technical scheme provided by the invention; The said cyclone separator group of efficiently gathering dust; Comprise prime cyclone separator and back level cyclone separator, some prime cyclone separators are and are connected in parallel, and the blast pipe of prime cyclone separator is connected in parallel into pump-line with the blast pipe of back level cyclone separator; Ash hole at every prime cyclone separator all is connected with the prime flue-dust retainer; The ash hole of back level cyclone separator is connected with back level flue-dust retainer, in the prime flue-dust retainer, is fixed with the prime installing rack, on the prime installing rack, is installed with the conical blast cap of prime; The vertex of a cone of the conical blast cap of prime has the gap between the awl feather edge of the conical blast cap of prime and the prime flue-dust retainer inwall up; Be connected in parallel to the air inlet pipe that cooperates with the platform number of prime cyclone separator on the air inlet of said back level cyclone separator, the inlet end of said air inlet pipe is arranged in the hypomere divergent-cone wall bottom of corresponding prime cyclone separator; In the level flue-dust retainer of back, be fixed with back level installing rack, on the level installing rack of back, be installed with the conical blast cap of back level, the vertex of a cone of the conical blast cap of back level has the gap between the awl feather edge of the conical blast cap of back level and the back level flue-dust retainer inwall up.
Said conical blast cap is coaxial setting with the hypomere divergent-cone wall of prime cyclone separator.The size of said prime cyclone separator is greater than the size of back level cyclone separator.
The phenomenon that the common thin grey secondary that takes place of the ash discharging hole of the prime cyclone separator among the present invention entrainments is eliminated, and significantly reduces through the powder containing quantity in the weary gas of level cyclone separator middle part, back 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 an overall structure sketch map of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: this cyclone separator group of efficiently gathering dust; Comprise prime cyclone separator 1 and back level cyclone separator 2; Some prime cyclone separators 1 are and are connected in parallel; The blast pipe of prime cyclone separator 1 is connected in parallel into pump-line 3 with the blast pipe of back level cyclone separator 2, all is connected with prime flue-dust retainer 4 at the ash hole of every prime cyclone separator 1, and the ash hole of back level cyclone separator 2 is connected with back level flue-dust retainer 9; In prime flue-dust retainer 4, be fixed with prime installing rack 5; On prime installing rack 5, be installed with the conical blast cap 6 of prime, the vertex of a cone of the conical blast cap 6 of prime has the gap between the awl feather edge of the conical blast cap 6 of prime and prime flue-dust retainer 4 inwalls up; Be connected in parallel to the air inlet pipe 7 that cooperates with the platform number of prime cyclone separator 1 on the air inlet of said back level cyclone separator 2, the inlet end of said air inlet pipe 7 is arranged in the hypomere divergent-cone wall bottom of corresponding prime cyclone separator 1; In the level flue-dust retainer 9 of back, be fixed with back level installing rack 10, on the level installing rack 10 of back, be installed with the conical blast cap 8 of back level, the vertex of a cone of the conical blast cap 8 of back level has the gap between the awl feather edge of the conical blast cap 8 of back level and back level flue-dust retainer 9 inwalls up.
Said conical blast cap 6 is coaxial setting with the hypomere divergent-cone wall of prime cyclone separator 1.The size of said prime cyclone separator 1 is greater than the size of back level cyclone separator 2.
The thin grey air-flow tangential that contains from grader outlet gets into prime cyclone separator 1, produces to rotatablely move strongly, and thin ash particle is got rid of to the wall of prime cyclone separator 1 under action of centrifugal force, slides to ash discharging hole and discharges downwards in that the effect of gravity is following then.In the process that the air-flow rotation moves down, a part of air-flow joins in the updraft on the line of separator axle center gradually, and the separated thin ash that gets off of another part air flow A and air continues to rotate downwards to enter into prime flue-dust retainer 4.Subsequently, most of thin ash leans on the effect of gravity to get into thin grey storehouse through lock gas discharge valve device downwards through prime flue-dust retainer 4 backs.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 the prime cyclone separator 1 under action of negative pressure at last once more; And carry a large amount of thin ashes, thereby reduce actual efficiency greatly.
In the present invention; Through the conical blast cap 6 of the prime in the prime cyclone separator 1 its top from prime flue-dust retainer 4 is drawn; Again add in the air-flow of back level cyclone separator 2, the blast pipe that utilizes prime cyclone separator 1 and the blast pipe of back level cyclone separator 2 be connected in parallel into pump-line 3 negative pressure extract out and the laggard inlet/outlet flue of grade cyclone separator 2 processing through the back.
For reducing overall height; Utilize two prime cyclone separator 1 structures of backrest type, thin grey air-flow gets into two prime cyclone separators 1 at cyclone inlet punishment two-way, and prime cyclone separator 1 diameter dwindles relatively; Under identical entrance velocity, have the bigger single separator of diameter group and have higher separative efficiency; 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 back level cyclone separator 2 is connected with back level flue-dust retainer 9.
Through such cyclone separator group; The phenomenon that the common thin grey secondary that takes place of the ash discharging hole of prime cyclone separator 1 entrainments is eliminated; Powder containing quantity through in the weary gas of back level cyclone separator 2 middle part central tubes discharges significantly reduces; 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.
