Description
Technical field
The utility model relates to high-temperature material cooling technology field, is specifically related to a kind of lime-ash cooling system of cement kiln associated treatment municipal refuse.
Background technology
The processing of municipal refuse has become the problem that the whole world is paid close attention to, becomes a great research topic of world today's environmental protection.At present trash processing way is that these two kinds for the treatment of technologies exist great drawback taking landfill and burning electricity generation as main.Landfill method takies the land resource of a large amount of preciousnesses, and it is long that the time is left in harm; Domestic a lot of destructor plant overload operation, new refuse landfill addressing is more and more difficult, adds the not in place of rubbish later regulation measure, and garbage disposal crisis is probably in more Urban Sprawl.Burning electricity generation can produce flying dust with the toxic and harmfuls such as bioxin cause secondary pollution.Especially waste incineration brings dioxin emission, is its main PE challenge facing.
Unique production technology (alkaline atmosphere, 1000 DEG C of above high temperature) of manufacture of cement provides good condition for processing domestic waste.L-type incinerator is that the supporting cement producing line that utilizes of a kind of and cement producing line is processed the system of municipal refuse.It is as follows that L-type incinerator is processed the technical process of municipal refuse system: municipal refuse is transported after factory by the cram packer sealing of municipal environmental sanitation department, delivers to after metering refuse-unloading platform, in hermatic door is discharged into garbage storing hole.Carry out homogenizing with grab bucket crane, then feed disintegrating machine processing, the rubbish after fragmentation is got back in storage hole; Feeding machine, belt feeder etc. through plate again sends in incinerator; Drawing quality coal in cement kiln systems tertiary air enters stove and carries out high-temp combustion; The flue gas that burning produces returns cement kiln dore furnace; The lime-ash producing after waste incineration is sent into cement raw meal mill after cooling, makes cement raw material batching and uses.
The lime-ash producing after utilize in the process system of cement kiln associated treatment municipal refuse, rubbish burns in L-type incinerator need to pass through cooling processing.The existing lime-ash type of cooling is air-cooled, and this type of cooling exists following drawback:
1, the impact on refuse burning system burning capacity: a large amount of cold airs are blasted cooler, and cooler is directly connected with L-type incinerator, and the cold air in cooler enters incinerator and causes whole CIU temperature drop obvious, and burning capacity declines.
2, the impact on burning situation in L-type incinerator: to go out the quantity of slag discontinuous due to L-type incinerator lime-ash, and the flue-gas temperature fluctuating range in air-cooled cooler enters incinerator is larger, causes in incinerator burning circumstance complication changeable, is difficult to control.
3, the impact on manufacture of cement firing system: the flue gas of the air-cooled generation of lime-ash enters cement producing line tertiary air through incinerator, can cause wind-warm syndrome to decline, and hear rate increases.Increase because air quantity increase can make the load of kiln tail high-temperature blower, power consumption increases simultaneously.In addition the fluctuation of temperature also can make the operating mode disorder of cement production system, and impact is normally produced.
Therefore, can either to meet lime-ash cooling for exploitation one, and the cooling technology that can not have a negative impact to refuse burning system and cement production system again just seems extremely important.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and a kind of lime-ash cooling system of cement kiln associated treatment municipal refuse is provided, the advantage such as having can continuous discharge, safe, the burning capacity that can ensure incinerator.
The utility model is for solving the problems of the technologies described above, the technical scheme providing is: the lime-ash cooling system of cement kiln associated treatment municipal refuse, the high-temperature ash of discharging in order to cooling L shaped incinerator, described cooling system comprises dreg-accepting hopper, air valve and spiral cooler, dreg-accepting hopper is arranged on the slag-drip opening place of L shaped incinerator, the lower end of dreg-accepting hopper is connected to spiral cooler by air valve, described spiral cooling apparatus has a conveying worm, the shell of conveying worm has interlayer, and the rotating shaft of conveying worm is hollow shaft, in the shell interlayer of conveying worm and in hollow shaft, be all connected with recirculated cooling water, the discharging opening below of conveying worm is provided with belt conveyor, the discharging end of belt conveyor arranges cinder tank.
Described dreg-accepting hopper is connected with triple valve by air valve, and two outputs of triple valve connect respectively two spiral coolers.
beneficial effect
1, the high-temperature ash to L-type incinerator that lime-ash cooling system of the present utility model is adopts cooling water indirectly cooling, the advantage of this process for cooling is can not have a negative impact to the burning situation of whole CIU and burning capacity, and can not cause the situations such as the reduction of manufacture of cement firing system temperature, air quantity increase and operating mode disorder.
2, lime-ash cooling system of the present utility model arranges air valve and triple valve between dreg-accepting hopper and spiral cooler, can in ensureing smooth blanking, reduce refuse burning system and leak out.
