Abstract

The utility model relates to a rotary pulse spraying dust removing device which organically combines a mechanical rotary mechanism and a pulse spraying mechanism. The utility model has the advantages of compact structure, and good dust removing effect and solves the disadvantages of poor effects on reverse blowing and dust removing of a mechanical rotary dust removing device, much investment in a pulse dust removing device and many frauds for maintenance care. The utility model is a dust removing device which is economical and practical with less investment.

Description

Rotary pulse winding-up deduster

The utility model relates to a kind of controlling device of industrial production flue dust, and especially thoroughly the rotary pulse of deashing winding-up deduster belongs to the dedusting technology field.

The deduster that present domestic smoke and dust treatment adopts has rotary counter-blowing sack cleaner and pulse bag type dust collector.The rotary counter-blowing sack cleaner is because its compact conformation, floor space is little, reduced investment, economical and practical, thereby obtained using widely, but because its reverse gas cleaning is a kind of weak power purge mode, behind the operation certain hour,, will produce the vicious circle of " the deashing ability becomes more weak in resistance rising---air quantity decline---" in case deashing does not reach expected effect, finally make deduster handle air quantity and drop to minimum level, influence the effect of deduster deashing greatly.Pulse bag type dust collector is owing to have powerful ash-removal effect, thereby adopted by people gradually, but owing to this deduster need be installed a pulse valve above every group of cloth bag, its quantity is big, investment is high, and difficult quality guarantee is given to administer and maintain and brought many inconvenience.

In order to reach good ash-removal effect, can save investment again, economical and practical, be convenient to safeguard, designed " rotary pulse winding-up deduster ".

The purpose of this utility model provides a kind of rotary pulse winding-up deduster, and it not only can purify flue gas, and can overcome and solve an ash-clearing technology difficult problem, reach to each position of filter bag carry out thoroughly, deashing equably.

The purpose of this utility model is achieved in that the slew gear spiral arm air outlet place in existing rotary counter-blowing deduster, set up one or several pulse valves, set up a cover compressed air source simultaneously, remove the back blowing machine deashing mechanism, slew gear and pulse jet mechanism are organically combined, to enter deduster under suction function simplified when dusty gas, filter by filter bag, purified gas is discharged through clean room, the dust on cloth bag surface is constantly piled up simultaneously, when its resistance reaches certain value, the rotary pulse spraying and blowing organ begins deashing, and it is under the stepper drive mode drives, and spiral arm is done periodically stepping rotation slowly above cloth bag, gases at high pressure that superincumbent pulse valve provides by compressed air gas source are installed to the below cloth bag, carry out transient pulse winding-up one by one, the dust that adheres on the filter bag shaken off down, and to each position of filter bag can both be thoroughly deashing equably, even the dewfall situation appearred in cloth bag, also can finish deashing preferably.

Use above purge mode, the ash-removal effect that can solve general rotary counter-blowing mechanism is poor, influences the difficult problem of efficiency of dust collection, and has simplified the labyrinth of general pulse dust collector greatly.Rotary pulse winding-up deduster is the novel deduster that integrates two strong big advantages of the compact conformation of revolution winding-up deduster and pulse dust collector deashing, therefore it is good to have ash-removal effect, compact conformation, cost of investment is low, advantages such as Maintenance and Repair are convenient, economical and practical, be easy to promote, be applicable to the purification of various industrial and mining enterprises industrial dust.

Below in conjunction with accompanying drawing and enforcement the utility model is further specified.

Fig. 1 is an example structure schematic diagram of the present utility model.

1. clean rooms, 2. rotary pulse spraying and blowing organs, 3. filter bags, 4. deduster cylindrical shells, 5. ash buckets, 6. unloading valves, 7. nozzles among the figure

Dusty gas is under the effect of air-introduced machine, enter deduster cylindrical shell 4 along tangent line, gas after the cyclonic separation continues to rise and filters through filter bag 3, purified gas is discharged by clean room 1, meanwhile, rotary pulse spraying and blowing organ 2 is done the rotation of stepping slowly, and the pulse valve nozzle 7 that is installed on the spiral arm regularly carries out instantaneous jetting deashing to filter bag 3 one by one by pulse valve control, dust on the filter bag is shaken off in the ash bucket 5, thereby finished deashing work.

Claims (3)

1, a kind of rotary pulse winding-up deduster mainly is made up of rotary pulse spraying and blowing organ and deduster cylindrical shell, it is characterized in that slew gear and utilizes the pulse valve of compressed air source to integrally combine.

2, rotary pulse winding-up deduster according to claim 1, it is characterized in that: the deduster cylindrical shell adopts round.

3, rotary pulse winding-up deduster according to claim 1 is characterized in that: adopt the stepper drive mode to drive slew gear, make spiral arm and pulse valve one by one to the filter-bag blowing deashing.
