Abstract
A flow guiding plate of a bag type dust remover solves the problems of uneven airflow distribution in a lower box body of the dust remover and larger impact of the airflow to the rear end body, and is characterized by the inclusion of a dust hopper body 4 of the dust remover and a flue gas inlet 2 of the dust remover, wherein a slot 1 is formed on the top edge of the dust hopper in the box body of the dust hopper body 4 of the dust remover; an inclined flow guiding plate 3 of the dust remover, with an inclined angle, is fixedly arranged in the box body of the dust hopper body 4 of the dust remover via the slot 1; and the inclined flow guiding plate 3 of the dust remover comprises a plurality of stepped partition boards. The utility model has the advantages of good dust removal effect, simple and convenient operation and practicality, and is applicable to the technical field of atmospheric pollution control engineering. Moreover, as the inclined flow guiding plate is arranged at the flue gas inlet of the dust remover, airflow can enter each cloth bag uniformly.
Description
Technical field
The utility model is specifically related to a kind of sack cleaner deflector, belongs to the technical field of plant equipment control air pollution engineering.
Background technology
Continuous development along with dedusting technology, especially the appearance of novel filter material, sack cleaner is with its efficiency of dust collection height, strong, the stable and reliable operation of adaptability, can handle the high concentration ash-laden gas, can satisfy strict day by day advantages such as environmental requirement, obtain using widely in industries such as cement, electric power, building materials.The bag chamber is the operating part of sack cleaner, and bag indoor air flow skewness can cause problems such as a bag chamber dust stratification, local filter bag damage.After air-flow is come in from air inlet, first motion is to deduster and grey bucket rear, and moves upward along rear wall, therefore at the wind speed at deduster rear portion than higher, and in deduster inside, air velocity is less relatively. the wind speed of rear portion and front portion than in addition reached more than 4 times.Simultaneously. the air velocity in two angle zones that deduster rear wall and sidewall form is also compared higher.On the whole, when not taking the airflow uniform distribution measure, the deduster interior flow field distributes very inhomogeneous, and the front and back wind speed differs huge, is unfavorable for the operation and the maintenance of deduster.Therefore, a bag indoor air flow is evenly distributed, stable, efficient operation has crucial meaning to sack cleaner.After the design of sack cleaner body and outlet conduit system was determined, airflow uniform distribution depended primarily on the airflow-distribution board type.Air-flow causes local ascending air too fast when inlet duct enters deduster at a high speed, and other parts then are the phenomenons of air dead band or countercurrent zone, thereby has reduced efficiency of dust collection, and the outlet flue gas concentration is increased, and makes the too early damage of cloth bag simultaneously.
Summary of the invention
The purpose of this utility model is exactly for remedying above deficiency, and what provide a kind ofly improves the uniformity that air-flow distributes in the deduster, reduces the sack cleaner deflector of the wearing and tearing of filter bag.
The utility model is to realize like this, the deflector of described a kind of sack cleaner, form by dust collector ash hopper 4 bodies and deduster flue gas air inlet 2, it is characterized in that one slot 1 being set in dust collector ash hopper body 4 box house ash bucket upper edges, in dust collector ash hopper body 4 casings, fixedly install an oblique deflector 3 of deduster that the angle of inclination arranged by slot 1, the oblique deflector 3 of deduster is made up of polylith staged dividing plate: plate is long, wide, after be respectively certain length, self inclination certain angle, SR is a certain particular value, plate is several determines that according to flue gas flow material is the particular iron alloy.By the fixing position of deflector of slot, at near the damaged easily shortcoming of the filter bag the existing sack cleaner air inlet, structure to sack cleaner has been carried out optimal design, several deflectors that descend gradually have been installed in the porch of deduster, to change gas flow direction, obtain almost ascending air uniformly.Deflector spread pattern difference, the interior air-flow of deduster distributes also different, and flue gas enters a bag chamber through air inlet, because wind speed is bigger, gas forms tangible jet action after entering deduster.After this strand jet enters ash bucket, continue up to ash bucket rear side body of wall.At this moment, the part air-flow rises at a high speed along back wall, causes this part sky to ask that filter bag asks that the speed of having a rest is excessive, and the bottom of filter bag is brought seriously wash away, and this just causes the filter bag of rear end damaged easily; Another part air-flow flows downward along back wall, and form to reflux in ash bucket, rises along the ash bucket front face, and meets with the jet of inlet, makes the upwards skew of direction of jet, and the part air-flow is along the front face of the filter chamber flow at high speed that makes progress.Simultaneously, because the particle that is filtered in deduster moves downward, when particle drops to the gas flow jet place, can be brought back to upper box again by high-speed jet again, so not only increased the weight of the load of filter bag, and wash away filter bag with higher speed, cause bag filter bag of chamber front end also damaged easily.After adding deflector near the deduster inlet, high velocity air enters sack cleaner, and air-flow is subjected to the influence of deflector, and the main flow direction of air-flow moves down, and divides some strands of air-flows to enter upper box equably under the effect of deflector.Shunting back air velocity is less relatively, and air-flow can not wash away filter bag band Mi Yanchong after entering deduster, and air-flow distributes also relatively evenly in the deduster.Because air-flow is shunted, air-flow diminishes to the impact of rear end element, and air-flow is pasting the back wall motion of deduster lower box always, and the drainage speed also speed than prototype is little, makes the interior air-flow of deduster lower box is evenly distributed.
The utlity model has the feasible interior air-flow of deduster lower box that can make and be evenly distributed, air-flow diminishes to the impact of rear end element, and good dedusting effect is simple to operation, practical advantage.
Description of drawings
Accompanying drawing is a kind of sack cleaner deflector structure figure
In the accompanying drawing
1 slot, 2 deduster flue gas air inlets, the oblique deflector of 3 dedusters, 4. dust collector ash hopper body.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified, a kind of as shown in drawings sack cleaner deflector, be to arrange slot in box house ash bucket upper edge, can be by the fixing position of deflector of slot, by adjust deflector the position of slot, adjust position and the arrangement form thereof of deflector in deduster.After oblique deflector was installed, air-flow had been divided into mass part under the effect of deflector, and each several part moves obliquely along the deflector of diverse location respectively.Because the effect of deflector, wind speed anterior and mid portion obtains increasing, and the rear portion wind speed is inhibited, thereby reaches the purpose of even distributing wind.
Claims (2)
1. the deflector of a sack cleaner, form by dust collector ash hopper (4) and deduster flue gas air inlet (2), it is characterized in that one slot (1) being set, between slot (1) and deduster flue gas air inlet (2), be provided with the oblique deflector of angle of inclination deduster (3) in dust collector ash hopper (4) box house ash bucket upper edge.
