The heat recovery in coal-fired flue-gas can be recycled again.
The content of the invention
For existing problem more than solving, returned the utility model discloses a kind of grain drier hot-blast stove fume dedusting waste heat
Receiving apparatus.
A kind of grain drier hot-blast stove fume dedusting waste-heat recovery device, including fume collection device, the fume collection
Device one end is connected with discharge duct, other end connection smoke conveying duct import, the smoke conveying duct outlet connection pulse
Blowback bag-type dust collector import, the pulse backblowing sack cleaner outlet connection pure air conveyance conduit import is described clean
Net air conveyance conduit is provided with air-introduced machine, the pure air delivery pipe outlet connection pure air distributor.
Further, the fume collection device is funnel-shaped structure, and big opening end and the discharge duct of funnel-shaped structure connect
Connect.
Further, the pure air distributor is also funnel-shaped structure, and osculum end and the cleaning of funnel-shaped structure
Airflow pipe is connected, and big opening end is connected with heat exchanger.
Further, the pulse backblowing sack cleaner includes deep bead, and the deep bead is V-shaped, the flue gas
Conveyance conduit is exported just to deep bead V-shaped bottom intersection point.
Further, the pulse backblowing sack cleaner also includes cloth bag, blowing device and ash bucket, the blowing device
Connected by injection tube with cloth bag.
Beneficial effect：By it is of the present utility model improve, hot-blast stove chimney structure can be cancelled, directly by discharge duct with
Fume collection device is connected, then by pulse backblowing sack cleaner, is removed the volume of smoke in flue gas and obtained pure air, clean
Net air finally enters back into heat exchanger, while the waste heat that pure air also retains in amount of heat, flue gas is recycled, subtracts
Lack energy resource consumption, improved grain drying efficiency, substantially increase economic benefit, also reach energy-saving and emission-reduction, the purpose of environmental protection.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Wherein, 1 is fume collection device, and 2 be smoke conveying duct, and 3 be pulse backblowing sack cleaner, and 301 be deep bead,
302 be cloth bag, and 303 be injection tube, and 304 be blowing device, and 305 be ash bucket, and 4 be pure air conveyance conduit, and 5 be air-introduced machine, 6
It is heat exchanger for pure air distributor, 7,8 be discharge duct.
Embodiment
With reference to accompanying drawing, the utility model is described in further details.
As shown in figure 1, a kind of grain drier hot-blast stove fume dedusting waste-heat recovery device, including fume collection device 1, institute
State the one end of fume collection device 1 to connect with discharge duct 8, the other end connection import of smoke conveying duct 2, the smoke conveying duct
The import of 2 outlet connection pulse backblowing sack cleaner 3, the outlet of the pulse backblowing sack cleaner 3 connection pure air conveying
The import of pipeline 4, the pure air conveyance conduit 4 is provided with air-introduced machine 5, and the outlet of pure air delivery pipe 4 connection is clean
Air sparger 6；The fume collection device 1 is funnel-shaped structure, and the big opening end of funnel-shaped structure is connected with discharge duct 8；
The pure air distributor 6 is also funnel-shaped structure, and the osculum end of funnel-shaped structure connects with the road of pure air delivery pipe 4
Connect, big opening end is connected with heat exchanger 7；The pulse backblowing sack cleaner 3 includes deep bead 301, and the deep bead 301 is V
Font, the smoke conveying duct 2 exports the V-shaped bottom intersection point just to deep bead 301；The pulse backblowing sack cleaner
3 also include cloth bag 302, blowing device 304 and ash bucket 305, and the blowing device 3 is connected by injection tube 303 with cloth bag 302.
The high-temperature flue gas that hot-blast stove is discharged is introduced into grain drier hot-blast stove fume dedusting waste-heat recovery device, flue gas
Pulse backblowing sack cleaner 3 is arrived through smoke conveying duct 2 by fume collection device 1, from the air intake of pulse backblowing sack cleaner 3
Mouth enters, and initially strikes the deep bead 301 in the middle of inlet and outlet, air-flow just turns to inflow ash bucket 305 obliquely, upward and oblique
Upper entrance cloth bag 302, while air velocity slows down, due to effect of inertia, makes coarse granule flue dust in gas flow directly into ash bucket
305, play a part of receiving bulky grain flue dust in advance, the air-flow into ash bucket 305 then can also be rolled over and be equipped with upwardly through inside
