Description
Technical field
The utility model relates to a kind of deduster, especially a kind of powerful ash-cleaning type high-temperature low-pressure off-line pulse packet deduster.
Background technology
In the stove high-temperature flue gas of AOD stove, electric furnace, converter, rotary kiln etc., generally use the bulky grain spark catcher to be connected, contain crude particle dust, because pipe flow speed reaches about 18m/s with sack cleaner; Be can not be in short tens seconds with its (surface cool) that cools down; These high temperature crude particle dust just are adsorbed onto on the cloth bag surface, and temperature also has several Baidu, burns out cloth bag; Causes system can not normally be moved; Discharging can not be up to standard, and often change cloth bag and cause unnecessary economic loss again, and is time-consuming.
The bulky grain spark catcher comprises casing, ash bucket and baffle plate; Wherein, casing can pass through gas smoothly, and flow velocity slows down; Ash bucket is as the container that stores dust; Baffle plate gets off the bulky grain dust arrestment.The course of work of bulky grain spark catcher is: in a coffin, flue dust is introduced into casing, is running into sloping baffle, and crude particle dust is fallen by gravity, and drops in the ash bucket and go, and gets into deduster again and filters.
This bulky grain spark catcher is simple in structure, with sack cleaner be not an integral body (generally being placed on the sack cleaner front end), waste material, uneconomical; Floor space is big, and the situation of leaking out is arranged, and can seriously disturb dusty gas to flow; Flue gas flow rate is high, is prone to form the interior secondary of casing and kicks up, and the dust of baffle plate is difficult to remove (using the labor cleaning); Sometimes make gas inhomogeneous, can produce phenomenons such as turbulent flow and eddy current, capture weak effect; It is little to reduce temperature, the cloth bag life-span of influence back sack cleaner, easy burn-out cloth bag.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, provide that a kind of efficiency of dust collection is high, the cloth bag life-span prolongs greatly, can operation steady in a long-term, flow velocity is little and even, capture effect high, reduce the big and effective powerful ash-cleaning type high-temperature low-pressure off-line pulse packet deduster of temperature.
The technical scheme that provides according to the utility model; Said powerful ash-cleaning type high-temperature low-pressure off-line pulse packet deduster; It is included in hard-wired two ash buckets on the frame; On the frame of top position between two ash buckets, be fixed with the intake stack that is vertical setting; Be provided with two cover flue gas water conservancy diversion deceleration plywoods in the intake stack bottom, to each self-corresponding ash bucket, every cover flue gas water conservancy diversion deceleration plywood cascades by the flue gas water conservancy diversion flap gap of some bendings two cover flue gas water conservancy diversion deceleration plywoods with the pending flue gas shunting that feeds in the intake stack; On the frame of intake stack both sides, all be fixed with sack cleaner; Each sack cleaner is arranged on the top of corresponding ash bucket, and sack cleaner has dust-removal cloth-bag, and the opening of dust-removal cloth-bag up; On the frame above the opening of dust-removal cloth-bag, be provided with impulse jet nozzle; The sack cleaner dedusting finishes, and described impulse jet nozzle optionally sprays into gas in the opening of dust-removal cloth-bag, makes the dust that is accumulated in the dust-removal cloth-bag outer surface fall in the corresponding ash bucket.
The Z-shaped plate body that described flue gas water conservancy diversion flap is connected to form by inclined board, connecting plate and declined board one, the bottom of inclined board and the top ends of connecting plate are joined in obtuse angle, and the bottom of connecting plate and the top ends of declined board are joined in obtuse angle.
Described impulse jet nozzle is included in the nozzle that the top middle portion of jet pipe is installed, and the intracavity space of jet pipe is coniform for what just putting, is provided with helical intake at the inwall of jet pipe; The hypomere of said nozzle is the straight-run of pipe body, and the epimere of nozzle is outer cast aside, curved surface pipe that axial section is shaped as circular arc from bottom to top.
The utlity model has that the coarse granule arresting efficiency is high, deashing property is strong, structural strength is high, the cloth bag life-span is long, efficiency of dust collection is high, deduster operation steady in a long-term, energy consumption is low, temperature tolerance good, antioxygen property and good corrosion resistance, floor space is little, cost is low with reduce advantages such as temperature effect is good.

The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: this brute force ash-cleaning type high-temperature low-pressure off-line pulse packet deduster; It is included in hard-wired two ash buckets 2 on the frame 1; On the frame 1 of top position between two ash buckets 2, be fixed with the intake stack 3 that is vertical setting; Be provided with two cover flue gas water conservancy diversion deceleration plywoods 4 in intake stack 3 bottoms; To each self-corresponding ash bucket 2, every cover flue gas water conservancy diversion deceleration plywood 4 cascades by flue gas water conservancy diversion flap 5 gaps of some bendings two cover flue gas water conservancy diversion deceleration plywoods 4 with the pending flue gas shunting that feeds in the intake stack 3; On the frame 1 of intake stack 3 both sides, all be fixed with sack cleaner 6; Each sack cleaner 6 is arranged on the top of corresponding ash bucket 2, and sack cleaner 6 has dust-removal cloth-bag 7, and the opening of dust-removal cloth-bag 7 up; On the frame above the opening of dust-removal cloth-bag 71, be provided with impulse jet nozzle 8; Sack cleaner 6 dedustings finish, and described impulse jet nozzle 8 optionally sprays into gas in the opening of dust-removal cloth-bag 7, make the dust that is accumulated in dust-removal cloth-bag 7 outer surfaces fall in the corresponding ash bucket 2.
The Z-shaped plate body that described flue gas water conservancy diversion flap 5 is connected to form by inclined board 5.1, connecting plate 5.2 and declined board 5.3 one; The top ends of the bottom of inclined board 5.1 and connecting plate 5.2 is joined in obtuse angle, and the top ends of the bottom of connecting plate 5.2 and declined board 5.3 is joined in obtuse angle.
Described impulse jet nozzle 8 is included in the nozzle 8.3 that the top middle portion of jet pipe 8.1 is installed, and the intracavity space of jet pipe 8.1 is coniform for what just putting, is provided with helical intake 8.2 at the inwall of jet pipe 8.1; The hypomere of said nozzle 8.3 is the straight-run of pipe body, and the epimere of nozzle 8.3 is outer cast aside, curved surface pipe that axial section is shaped as circular arc from bottom to top.
The nozzle 8.3 of rounding arc can make jet amount more, and ash-removal effect is better; Helical intake 8.2 can make the gas of nozzle 8.3 ejections in jet pipe 8.1, form eddy current, has more strengthened ash-removal effect.
In each sack cleaner 6, have some reinforcement templates 11 of horizontally set.
In the utility model when work, feed the pending flue gas of the high heat of high temperature by intake stack 3, and pending flue gas is during through every cover flue gas water conservancy diversion deceleration plywood 4; Bulky grain thing in pending flue gas bump connecting plate 5.2 and slow down and fall in the ash bucket 2, pending flue gas are during through the bent passage between two flue gas water conservancy diversion flaps 5, and speed reduces greatly; The pending flue gas that speed reduces slowly rises, and in the process that slowly rises, pending flue-gas temperature reduces greatly; When passing through the dust-removal cloth-bag 7 of sack cleaner 6 then, dust is collected in the outer surface of dust-removal cloth-bag 7, after handling a period of time; Start winding-up gas bag 9, impulse jet nozzle 8 swirl gas of jetting in the opening of dust-removal cloth-bag 7 is blown down the dust that dust-removal cloth-bag 7 outer surfaces accumulate; Fall in the ash bucket 2, the dust in the ash bucket 2 is seen off by conveying worm defeated 10.
