Abstract
The dry cinder-removing machine includdes machine body, on the machine body the driving rollers and driven rollers are mounted, as endless steel band is mounted around the driving and driven rollers, the upper portion of the endless steel band is working portion, and the undersurface of working portion of supported by water-changed pad bed mounted on the machine body. Said invention is reasonable in structure, in the course of removing cinder said cinder does not contact with water. In the cinder-cooling machine its cooling medium is air and make-up water of boiler or circulating water, the air absorbing cinder heat can be fed into furnace cavity to help combustion, and the water absorbing cinder heat can raise water temp. of boiler so as to raise heat efficiency of boiler, and the dried cinder can be used as cement clinke.
Description
(1) technical field
The present invention relates to a kind of ash handling that belongs to the boiler accessory machinery technical field, is a kind of dry slag-removing machine specifically.
(2) background technology
The coal-fired powder boiler of large-sized boiler, particularly 100MW-700MW scope, the red-hot lime-ash that it has burnt has about 15% process furnace bottom slag well arrays to go out.At present, handle this part furnace bottom lime-ash and need the flame-out and cooling of water, i.e. wet type slagging-off.Shortcoming is to need with a large amount of water, and the heat that red-hot slag contained does not reclaim yet, and causes the waste of the water resource and the energy.At present, also emerging a kind of net belt type pnenmatic slag handling equipment, shortcoming is a complex structure, the cost height, maintenance workload is big, and the operating cost height is to the burner hearth burnt bad adaptability of impacting of collapsing.
(3) summary of the invention
The object of the invention is to propose a kind of dry slag-removing machine at the shortcoming in the existing wet type slagging-off technology, makes it when handling the red-hot lime-ash of furnace bottom of coal-fired powder boiler, can using water wisely, can reclaim heat again.
The object of the invention is realized by following technical scheme: this dry slag-removing machine, include body, it is characterized in that being equipped with on the body initiatively roller and passive roller, initiatively roller and passive roller is peripherally equipped with belt steel band, the go in ring top of steel band is the impulse stroke section, impulse stroke section following by the water-filling equalizing bed rest that is contained on the body.
One end of belt steel band connects slag and stays, and the outlet that slag stays connects cold slag machine, can select cylinder type cold slag machine for use, and there is slag chute the steel band top of going in ring.
The go in ring bottom of steel band is the backhaul section, backhaul section following by the carrying roller rest that is contained on the body.
The operation principle of dry slag-removing machine is: the red-hot lime-ash that is gone out by boiler slag well array drops on the belt steel band of the slag chute bottom land that is positioned at dry slag-removing machine, slowly the belt steel band of operation transports slag chute with red-hot lime-ash, stay the cold slag machine that enters through slag, cold slag machine is cooled to below 150 degrees centigrade lime-ash, so that the lime-ash storing.The steel band that goes in ring is dragged passive roller tensioning by the active roller.Its impulse stroke section by the water-filling equalizing bed holder below it, and the water of water-filling equalizing bed also has cooling effect, makes the temperature of the steel band that goes in ring can be too not high; The backhaul section is moved on carrying roller, and carrying roller makes the steel band backhaul Duan Buhui that goes in ring sagging.The carrying roller number is according to the steel band length decision of going in ring, and idlers pitch is generally 1-1.5 rice.
Cold slag machine, slag stays and the position of slag chute is fixed, and remainder is contained on the body, can move together along with the body that four wheels are housed, so that the maintenance of boiler and dry slag-removing machine.
Advantage of the present invention is that structure is more reasonable, and is simple, and cooling principle is different with the wet type slagging-off, do not contact water at slagging-off overall process lime-ash, so consume water not in energy using water wisely today of water scarcity, is highly profitable; In cold slag machine, the cooling medium of red-hot lime-ash is air and boiler feedwater or recirculated water, and the air that absorbs slag heat is inhaled into burner hearth water combustion-supporting and absorption slag heat and has improved boiler feed temperature, thereby the lime-ash heat is reclaimed, improve boiler thermal output, better saved the energy.Dried slag can also be subscribed as clinker by the cement plant, makes full use of.Cost is low, and maintenance workload is little, and operating cost is low, is not afraid of burner hearth and collapses and burnt impact long service life.
(4) description of drawings
Fig. 1 is a kind of dry slag-removing machine vertical profile schematic diagram,
Fig. 2 is the cross-sectional schematic diagram of this dry slag-removing machine,
(5) specific embodiment, accompanying drawings
This dry slag-removing machine, include body 9, wheel is housed below the body, initiatively roller 5 and passive roller 1 are housed on the body, initiatively roller 5 and passive roller 1 is peripherally equipped with the steel band 3 that goes in ring, the end of steel band of going in ring connects slag and stays 6, and slag stays 6 outlet to connect cold slag machine 7, and there is slag chute 2 the steel band top of going in ring.
The go in ring top of steel band is the impulse stroke section, impulse stroke section following by water-filling equalizing bed 4 rests that are contained on the body.The go in ring bottom of steel band is the backhaul section, backhaul section following by carrying roller 8 rests that are contained on the body.
Claims (3)
1, a kind of dry slag-removing machine, include body, it is characterized in that being equipped with on the body initiatively roller and passive roller, initiatively roller and passive roller is peripherally equipped with belt steel band, the go in ring top of steel band is the impulse stroke section, impulse stroke section following by the water-filling equalizing bed rest that is contained on the body.
2, according to the described dry slag-removing machine of claim 1, it is characterized in that the end connection slag of belt steel band stays, the outlet that slag stays connects cold slag machine, and there is slag chute the steel band top of going in ring.
3, according to the described dry slag-removing machine of claim 1, the bottom of the steel band that it is characterized in that going in ring is the backhaul section, backhaul section following by the carrying roller rest that is contained on the body.
