Abstract
The utility model discloses a spiral axially air-taking multi-tube duster comprising an upper and a lower smoke boxes, a conduit tube box body and as ash bucket. The utility model is characterized in that a spiral type guide tube is composed of a guide tube and a guide plate arranged outside the spiral type guide tube and the bottom of the ash bucket is provided with a locking device. The guide plate is a spiral line type guide plate, and a log spiral line type guide plate is the best. The guide plate wraps three quarters of the outer circumference of the guide tube. The utility model has the advantages of reasonable and compact structure, corrosion resistance, long service life and high integration. The dust removing efficiency is more than 94%, and the pressure loss is less than 0.9 kpa. The material of the duster is cast-iron. Consequently, the duster has strong abrasive resistance and strong adaptability to the variation of coal types and boiler load.
Description
The utility model belongs to environmental protection equipment, is specially adapted to the boiler smoke dedusting.
Cleaner commonly used at present has electric cleaner, granite water dust scrubber and cyclone dust collectors.Though the efficiency of dust collection of electric cleaner is high, the equipment complexity, the specification requirement height, maintenance, safeguard, the operation workload is big, expense height, and relatively poor to bulky grain dust dust removing effects; The granite water dust scrubber, water consumption is big, needs the waste water recycling equipment, otherwise can cause secondary pollution, also causes the back-end ductwork chemical attack easily.Cyclone dust collectors then specification requirement are low, are a kind of general cleaners, but the cyclone dust removal apparatus efficiency of dust collection that uses at present is low, because mechanical wear, easy worn out causing of cylindrical shell scraps, and service life is shorter.
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of efficiency of dust collection height, simple in structure, cost is low, reduce the pressure loss, reduce the deduster of equipment volume, long service life.
The technical solution of the utility model is achieved in that helical axis is to the air admission type multi-tube dust cleaner, comprise upper smoke box, lower smoke box, conduit casing and ash bucket, the smoke inlet pipe is located on the lower smoke box, smoke outlet tube is located on the upper smoke box, spiral mozzle is arranged in the lower smoke box, be provided with the cone pipe in the conduit casing, insert in the cone pipe spiral mozzle lower end, it is characterized in that spiral mozzle is made up of mozzle and the deflector that is contained in its outside, the lock opening device is housed bottom the ash bucket.Ash-laden gas enters the lower smoke box of deduster through inlet, annular space along spiral mozzle and cone pipe flows from top to bottom, under the leading effect of the helical duct of deflector, make high speed rotary motion along the mozzle outer wall, because the effect of rotation produces centrifugal sedimentation power at a high speed, dust granules is thrown toward the cone inside pipe wall, and falls into ash bucket along the cone pipe, and the flue gas after being cleaned enters chimney from top to bottom along spiral mozzle and discharges.Fall into the dust of ash bucket, be pooled to certain amount, back down the lock opening device by the effect of its deadweight and discharge automatically, the lock opening device is loaded with counterweight, and when in the ash bucket low amounts of dust being arranged, the lock opening device pins the cleaning door of ash bucket bottom by the effect of counterweight, realizes automatic ash removing.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structure chart of the present utility model.
Accompanying drawing 2 is a spiral stream guidance duct ligation composition.
Accompanying drawing 3 is deflector structure figure.
Accompanying drawing 4 is lock opening device structure chart.
With reference to accompanying drawing, the utility model comprises upper smoke box 1, lower smoke box 4, conduit casing 6 and ash bucket 8, smoke inlet pipe 11 is located on the lower smoke box 4, smoke outlet tube 2 is located on the upper smoke box 1, spiral mozzle is arranged in the lower smoke box 4, is provided with cone pipe 7 in the conduit casing 6, and insert in the cone pipe 7 spiral mozzle lower end, it is characterized in that spiral mozzle is made up of mozzle 3 and the deflector 5 that is contained in its outside, ash bucket 8 bottoms are equipped with and are locked opening device 10.For making the air-flow rotation meet the movement locus of grit, deflector 5 is the helix deflector, is preferably the log spiral deflector, and it is around mozzle 3/4 week of 3 outsides, and deflector 5 is perpendicular to mozzle 3 axis.The utility model is the multitube type, and spiral mozzle is at least more than three, and uniform being arranged in the lower smoke box 4 is fixed by bolts on the dividing plate of smoke box.Cone pipe 7 is corresponding one by one with spiral mozzle, is fixed by bolts on the dividing plate of casing 6 and lower smoke box 4 and ash bucket 8.Mozzle 3 and cone pipe 7 are cast iron, and deduster is installed on the support 9.Lock opening device 10 is made up of supporting mass 12, counterweight 13, cross bar 14, depression bar 15 and hyoplastron 16, hyoplastron 16 is suspended on the supporting mass 12 by chain sling, depression bar 15 is pushed down hyoplastron 16 and hinged with cross bar 14, one end of cross bar 14 is hinged on the supporting mass 12, one counterweight 13 is arranged on the cross bar 14, counterweight 13 can move on cross bar 14, to adjust the pressure to hyoplastron 16.Hyoplastron 16 is one deck elastomeric material by cleaning door one side, to guarantee the sealing of deduster inside.The utility model is a split-type structural, upper smoke box 1, lower smoke box 4, conduit casing 6 are cylindrical shape, ash bucket 8 is a taper barrel, and upper smoke box 1 is connected with ash bucket 8 usefulness flanges with conduit casing 6, conduit casing 6 with lower smoke box 4, lower smoke box 4, smoke inlet 11 and outlet 2 relative arrangements.
The utlity model has following advantage:
1, the utility model adopts the multitube parallel pattern, has adopted the spiral plate guiding but rotatablely move, and has greatly simplified device structure, when having overcome general multitube parallel, affects the factor of dust removing effects because of gas distribution inequality or import obstruction etc. The indexs such as efficiency of dust collection of the present utility model and the pressure loss are and are better than general series and parallel structure, and the actual measurement dust removal efficiency is more than 94%, and the pressure loss is less than 0.9KPa.
2, these practical 9 compact conformations are reasonable, and floor space is little, no auxiliary device, and ensemble degree height is suitable for supporting installation and the transformation of power plant and various industry, boiler for domestic and kiln. The utility model steel consumption lacks 30-50% than like product, owing to adopt split-type structural, dust removing tube is with bolts, is convenient to maintenance and changes easily worn part.
3, spiral mozzle and cone piping cast iron quality are corrosion-resistant, wearability, and operation 8-10 can not influence the equipment operation because of wearing and tearing.
4, the utility model is strong to coal variation and boiler load variation adaptability, and when boiler reduced to 50% by design load (100%) load, efficiency of dust collection descended＜1%.
5, the utility model collection technique for smoke, gravity, bump and isolation technics are one, cut particle diameter dc50＜5 μ m, and import flue gas utilization velocity variations makes the bigger grit natural subsidence of part.Even because of gas distribution, avoid dust concentration too high and reduce the efficiency of dust collection of each separator.
