Abstract
A rotary low-pressure pulse dust-removing apparatus for the bag filters is composed of a pulse valve with an inlet connected to low-pressure air tank and an outlet connected to a rotary blowing trunk driven by motor, and at least one horizontal blowing tube connected to the lower end of said blowing trunk and with several nozzle for blowing air downward to the several bag filters.
Description
Technical field
The present invention relates to a kind of deashing device of removing the bag-type duster filtering bag dust stratification, particularly low pressure rotary pulse ash remover.
Background technology
Bag dust collector is widely used in flue gas, the gas cleaning that coal-burning boiler, metallurgy, building materials etc. produce the dust occasion.Dusty gas filters by filter bag, dust is blocked in outside the bag, purified gas passes through and outwards discharging in filter bag, and be provided with one the cover corresponding soot cleaning system, after deduster work a period of time, under the control of pulse valve, by nozzle blowback in filter bag, filter bag outside adhered dust is blown off, to recover the through-current capacity of deduster.In the filter bag type deduster, a plurality of concentrically ringed circumferential arrangement in a row arranged or press by filter bag on orifice plate, traditional deashing device is provided with numerous small-sized pulse valves and mesohigh (0.2～0.7Mpa), adopt the fixed pulse nozzle to blow filter bag during deashing, this kind structural device is huge, the energy consumption height, and also numerous pulse valves brings heavy operation and maintenance load, ash-removal effect is undesirable, and the easy excessive expansion of filter bag and damaging.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, occupation of land is little, cost is low and the sack cleaner low pressure rotary pulse ash remover of maintenance and convenient operation and management, to address the above problem effectively.
Purpose of the present invention adopts following technical proposals to realize:
This low pressure rotary pulse ash remover is provided with pulse valve, the import termination low pressure gasholder of pulse valve, the air intake duct of air accumulator is provided with Pressure gauge and control valve, the port of export of pulse valve is connected to the header pipe by the motor-driven rotation, this rotation header pipe lower end is provided with at least one the horizontal airduct that communicates with it, and each horizontal airduct is equipped with several jet nozzles downwards; Said pulse valve specification is 8～10 inches, and thickness is 3mm, pulse 0.1～0.085Mpa.
This deashing device is installed in the top of sack cleaner, horizontal airduct stretches into the top of the filter bag round plate of sack cleaner air-purifying chamber, as header pipe when the horizontal airduct of drive together rotates under motor-driven, pulse valve is gone into the header pipe with the action of low-voltage pulse pneumatic transmission, and jet downwards by each nozzle of horizontal airduct, to blow off attached to the dust stratification on the bag-type duster filtering bag in the ash bucket, reach the deashing purpose.
The nozzle that this deashing device drives by rotating air-duct is to numerous filter-bag blowing pulse gas, a large-scale pulse valve only need be set just can replace numerous pet-valves to finish deashing process to filter bag, not only ash-removal effect is good, the operating efficiency raising, energy consumption reduces, simple in structure, take up an area of and lack, cost is low, be convenient to promote the use of, and large-scale pulse valve intensity height, service life is long, has significantly reduced the workload of maintenance.The present invention adopts low pressure, atm number deashing pattern, has overcome the violent problem that expands of the filter bag high, that middle pressure deashing causes, and has increased the life-span of filter bag.
Description of drawings
Fig. 1 represents the structure of low pressure rotary pulse ash remover and the position relation of sack cleaner.
Fig. 2 is the A-A generalized section of Fig. 1.
Among the figure, 1-air intake duct, 2-control valve, 3-Pressure gauge, 4-low pressure gasholder, 5-pulse valve, 6-header pipe, the horizontal airduct of 7-, 8-nozzle, 9-motor, 10-header pipe's back shaft, the 11-sack cleaner, 12-air-purifying chamber, the outlet of 13-pure qi (oxygen), 14-1～14-n-filter bag, 15 filter bag round plates.
The specific embodiment
Below in conjunction with the description of drawings embodiments of the invention.
As shown in the figure, this rotary pulse ash remover is provided with the pulse valve 5 that links to each other with motor 9, the import termination low pressure gasholder 4 of pulse valve 5,3 millimeters of throttle slice thicknesses; The air intake duct 1 of air accumulator 4 is provided with Pressure gauge 3 and control valve 2, the port of export of pulse valve 5 is connected under motor 9 drives, header pipe 6 with 1 circle/minute rotation, this rotation header pipe lower end is provided with two horizontal airducts 7 that communicate with it, and each horizontal airduct 7 is equipped with several jet nozzles 8 downwards.When starter motor 9 makes 6 rotations of the horizontal airduct of header pipe's 7 drives, the air of being sent into by air inlet pipe 1 is through air accumulator 4 step-downs, produced 0.085Mpa low-tension pulse qi of chong channel ascending adversely and jetted downwards from each nozzle 8 of the horizontal airduct 7 that rotating by pulse valve.This deashing device of expression is installed on the bag-type duster filtering bag round plate 15 by header pipe's back shaft 10 among the figure.
Fig. 2 represents, is provided with filter bag round plate 15 in this example in the cabinet of sack cleaner 11, and this round plate is provided with filter bag 14-1, the 14-2 that arranges by concentric circles ... 14-n.Each filter bag is suitable for reading freely to be opened on each the corresponding aperture 15-n that is fixed on filter bag round plate 15.When ash-laden gas feeds from deduster 11 bottoms, dust is by filter bag 14-n filtering, and pure qi (oxygen) penetrates in the bag and from sack and upwards enters air-purifying chamber 12, discharges from exporting 13 subsequently.When treating that the dust stratification amount in the filter bag outside is big, start deashing device of the present invention, be pressed into air to low pressure storage tank 4, by the pulse gas of pulse valve 5 output 0.085Mpa by the header pipe that rotating 6, two horizontal airducts 7, jet in the filter bag downwards from each nozzle 8, the dust stratification in the filter bag outside is blown off in the ash bucket, thereby can recover the flux of filter bag.
It is 200 milliseconds that this example adopts the burst length, and be 5-60 second interpulse period, and pulse primary air amount is 2 meters
3/ time.
