Abstract
The utility model discloses an air tank pulse bag type dust collector, which comprises a tank body, a machine frame, a dust collecting cone, a dust discharge valve and a counter blowing dust cleaningdevice. The lower end of the tank body is arranged on the machine frame; the dust collecting cone is arranged below the tank body; the dust discharge valve is mounted at the lower end of the dust collecting cone; the counter blowing dust cleaning device is arranged at the top part of the tank body; the air tank pulse bag type dust collector also contains an air cannon; the air cannon comprises a high pressure air bag, a quick air exhaust valve, an exhaust pipe and a guide pipe; the guide pipe consists of a bent pipe at the upper part and a straight pipe at the lower part; the high pressure airbag is arranged at the external side of the dust collecting cone; the inlet end of the exhaust pipe is arranged in the high pressure air bag; the quick air exhaust valve is arranged on the high pressure air bag and is connected with the inlet end of the exhaust pipe; the guide pipe is arranged on the internal wall of the dust collecting cone through a bracket; and the bend pipe at the upper partof the guide pipe is connected with the outlet of the exhaust pipe. The air tank pulse bag type dust collector can timely clean the dust and collect the dust on the internal surface of the dust collecting cone, so as to prevent the accident of dust explosion from happening.
Description
Technical field
The utility model relates to a kind of fume dust remover, especially a kind of air box impulse bag-type dust remover.
Background technology
Air box impulse bag-type dust remover is widely used in the dedusting of flue gases such as the cement in vertical kiln, dryer of cement industry, and it contains casing, dust collection awl, blast pipe, exhaust duct, filter bag, ash-valve, anti-blow cleaning dust device and frame.The lower end of casing is fixed on the frame, and the dust collection awl is arranged on the below of casing, and ash-valve is installed in the lower end of dust collection awl, and filter bag is arranged in the casing, and blast pipe and exhaust duct are arranged on the casing, and the anti-blow cleaning dust device is arranged on the top of casing.After dusty gas was in blast pipe enters casing, gas passed filter bag, and dust is delayed at the outer surface of filter bag, and dusty gas is purified, and purified gas enters the exhaust duct discharge through the inside of filter bag.Detention falls into because of self gravitation in the dust collection awl in the part of the dust of filter bag outer surface, and the dust that falls in this awl is discharged by ash-valve.After the running resistance of deduster is increased to certain value, the work of anti-blow cleaning dust device, blowback wind enters in the filter bag, originally the filter bag that shriveled expands distortion, remove the dust that the filter bag outer surface adheres to, the dust under falls in the dust collection awl clearly, discharges by ash-valve.Because the dust collection awl is the planform of chamfered edge platform, so after deduster work a period of time, on the inner surface of dust collection awl the thicker dust of one deck is always arranged.Because the existence of this layer dust, when colliding with it in the dust on the filter bag outer surface falls into this awl, the dust concentration of dust collection awl heightens, and this will cause the generation of dust explosion accident easily.In order to remove the dust of dust collection awl inner surface, adopt the method for beaing or vibrate collection cone usually, but this is easy to make the dust collection awl impaired.
The utility model content
The technical problems to be solved in the utility model provides a kind of air box impulse bag-type dust remover, and this deduster can in time be removed the dust on the dust collection awl inner surface, in order to avoid the generation of dust explosion accident.
For solving the problems of the technologies described above, the utility model contains casing, frame, the dust collection awl, ash-valve and anti-blow cleaning dust device, the lower end of casing is arranged on the frame, the dust collection awl is arranged on the below of casing, ash-valve is installed in the lower end of dust collection awl, the anti-blow cleaning dust device is arranged on the top of casing, also contain air bubble, this big gun comprises the high pressure gas bag, rapid escape valve, blast pipe and guiding tube, guiding tube is made of the bend pipe on top and the straight tube of bottom, the high pressure gas bag is arranged on the outside of described dust collection awl, the entrance point of blast pipe is positioned at the high pressure gas bag, rapid escape valve is arranged on that high pressure gas is wrapped and links with the entrance point of blast pipe, guiding tube is arranged on the inwall of dust collection awl by support, and the bend pipe on guiding tube top is connected with the outlet of blast pipe.
Owing on the dust collection awl, set up air bubble, the dust of boring inner surface through guiding tube, with dust collection from the high velocity air of air bubble blast pipe ejection is discharged through ash-valve at the bottom of blowing and being flushed to this awl like this, the timely like this dust of having removed on the dust collection awl inner surface has effectively prevented the generation of the dust explosion accident that prior art causes easily because of this awl inner surface thicker dust.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
1. frames in the accompanying drawing, 2. casing, 3. dust collection awl, 4. anti-blow cleaning dust device, 5. bend pipe, 6. blast pipe, 7. high pressure gas bag, 8. rapid escape valve, 9. ash-valve, 10. straight tube.
The specific embodiment
In the accompanying drawing, air box impulse bag-type dust remover contains casing 2, dust collection awl 3, blast pipe, exhaust duct, filter bag, ash-valve 9, anti-blow cleaning dust device 4 and frame 1.The lower end of casing 2 is fixed on the frame 1, and dust collection awl 3 is arranged on the below of casing 2, and ash-valve 9 is installed in the lower end of dust collection awl 3.Filter bag is arranged in the casing 2, and blast pipe and exhaust duct are arranged on the casing 2, and be not shown in the figures.Anti-blow cleaning dust device 4 is arranged on the top of casing 2.Air box impulse bag-type dust remover also contains air bubble, and this big gun comprises high pressure gas bag 7, rapid escape valve 8, blast pipe 6 and guiding tube.Guiding tube is made of the bend pipe 5 on top and the straight tube 10 of bottom.High pressure gas bag 7 is arranged on the outside of dust collection awl 3, the entrance point of blast pipe 6 is positioned at that high pressure gas bag 7, rapid escape valve 8 are arranged on the high pressure gas bag 7 and links with the entrance point of blast pipe 6, guiding tube is arranged on the inwall of dust collection awl 3 by support, and the bend pipe 5 on guiding tube top is connected with the outlet of blast pipe 6.During work, dusty gas in blast pipe enters casing 2 after, gas passes filter bag, dust is delayed at the outer surface of filter bag, dusty gas is purified, purified gas enters exhaust duct through the inside of filter bag and discharges.Detention falls into because of self gravitation in the dust collection awl 3 in the part of the dust of filter bag outer surface.After the running resistance of deduster is increased to certain value, 4 work of anti-blow cleaning dust device, blowback wind enters in the filter bag, originally the filter bag that shriveled expands distortion, remove the dust that the filter bag outer surface adheres to, the dust under falls in the dust collection awl 3 clearly, discharges by ash-valve 9.Owing on dust collection awl 3, set up air bubble, like this from the high velocity air of air bubble blast pipe 6 ejection through guiding tube, dust collection is bored dust on 3 inner surfaces thoroughly to be blown and discharges through ash-valve 9 at the bottom of being flushed to this awl, can in time remove dust collection like this and bore dust on 3 inner surfaces, effectively prevent the generation of the dust explosion accident that prior art causes easily because of the thicker dust of this awl inner surface.
