Description
Affiliated technical field:
The utility model relates to a kind of life refuse high temperature burning device.
Background technology:
Along with improving constantly of the increasing and people's living standard of progress, the population of expanding economy, society, the house refuse amount that produce every day will increase.It is reported that the annual production of house refuse per capita of China at present reaches 400kg/ (man-year), and annual average rate of increase is 7～10%, existing more than 200 city, the whole nation surrounded by rubbish.
China's technology of garbage disposal is also quite backward compared with developed countries at present, and most of heap that adopts buries processing, and part is used for combustion power generation etc., heap buries processing and not only takies a large amount of soils, and soil, underground water, atmosphere etc. are worked the mischief, serious environment pollution jeopardizes the human living space.The burning city domestic garbage treatment technology can reach and subtract appearanceization, innoxious and resource, thereby extremely the parent of developed country looks at.Existing domestic incineration treatment of garbage mode mostly is the fire grate combustion-type greatly, adopts fluidized combustion on a small quantity, the overall technology level is lower, on the other hand along with the increase of macromolecular compound content such as plastics in the rubbish, this traditional mode itself can produce new toxic pollutant again in processing procedure, lime-ash after handling simultaneously fails again to make full use of, so existing treatment technology can not adapt to the human kind sustainable development needs.
In order to alleviate human survival environment is brought the pressure of destruction, developed country has begun to advocate and striving for the zero-emission (zero emission) of garbage disposal.According to the characteristics of the existing technology of garbage disposal of developed country and China's domestic waste, we have proposed domestic waste new type high temperature burning generation technology, and have successfully developed life refuse high temperature burning device on this basis.
Summary of the invention:
The purpose of this utility model is a kind of novel life refuse high temperature burning device of design, and house refuse reaches after this combustion furnace is handled and subtracts appearanceization, innoxious and resource, can not produce too much harmful substance in the processing procedure.
The purpose of this utility model is to realize like this, described life refuse high temperature burning device, comprise electronic transporter grab crane, the rubbish storage warehouse, the garbage feeding bucket, material-pulling device, feeding cylinder, combustion furnace, discharge slag-discharge apparatus, filtration equipment for clarifying and gas holder, the rubbish storage warehouse is provided with electronic transporter grab crane, the rubbish storage warehouse is by the garbage feeding bucket, feeding cylinder is linked combustion furnace, the feeding cylinder rear portion is provided with material-pulling device, its design feature can be by the fire grate of driven by motor rotation to spaced apart for be provided with at least three horizontal rows at place, combustion furnace middle and lower part, every fire grate sways, and axle is connected with motor by reductor; Be provided with seed region in the fire grate bottom, the seed region bottom is to dial slag spare, and it connects group slag transmission device down to dial slag spare; Be provided with discharge slag-discharge apparatus on the furnace bottom that is positioned under group slag spare, the import of discharge slag-discharge apparatus is positioned at dials below the slag spare, and outlet is positioned at outside the stove; Be provided with the outlet of burning gas on combustion furnace top, the outlet of burning gas is connected with filtration equipment for clarifying, and filtration equipment for clarifying connects gas holder.
The purpose of this utility model also can be achieved through the following technical solutions, described life refuse high temperature burning device, and its characteristics are that the fire grate in the combustion furnace is three horizontal rows to the fire grate of uniformly-spaced arranging, the seed region in the fire grate bottom is provided with auxiliary fuel burners.
The utlity model has following characteristics, 1) high temperature burning process is that rubbish is sent the garbage feeding bucket from the rubbish storage warehouse to by the special use grab bucket of electronic transporter grab crane, borrow the rubbish deadweight to fall into feeding cylinder, pushed in the combustion furnace by the hydraulic pressure material-pulling device then, feeding mouth is provided with sealing device.The fuel gas that is produced in the burning process flows directly into filtration equipment for clarifying, the branch flow container of process filtration equipment for clarifying is handled to deliver in the gas holder and is stored, then can enter gas turbine after the compressed machine compression, fuel gas turns to flue gas after the high-pressure combustion igniting of combustion gas combustion machine, flue gas enters underground piping.So advancing combustion furnace by rubbish, the burning overall process all is in the whole sealing status current downflow, so do not need to establish in addition smoke stack emission to driving the gas turbine running; 2) normally in service, the high temperature section of the burning zone of high temperature combustion furnace remains on about 850-1200 ℃; 3) the high temperature burning can be converted into the organic matter in the rubbish storage characteristics energy based on fuel gas; 4) the high temperature burning is to finish in the negative oxygen condition in stove, makes harmful components such as sulphur in the rubbish, heavy metal be fixed on waste residue---in the carbon black, and waste residue can be used for doing the construction material filler, removes the secondary pollution that the waste residue landfill is caused from; 5) because the burning section keeps higher temperature, harmful components content is low than the incinerator burning in its gas, can reduce the pressure of filtration equipment for clarifying significantly for this reason; 6) in the high temperature burning operate as normal, because the burning section keeps higher temperature, the heat energy that rubbish is produced in burning enough satisfies heat energy required in the rubbish burning, thus do not need outside any combustion-supporting material to replenish heat energy, as long as initially light; 7) the high temperature burning is to adopt the fuel gas that burning produced to remove to drive gas turbine, is not to burn the generation high-temperature steam to remove to drive steam turbine, so water consumption can reduce significantly in the whole system process; 8) in entering combustion furnace, rubbish just carries out preheating, drying, burning, burning four processes in the high temperature burning process.Whole high temperature burning temperature is high than burning, so combustion gas purity height, the exhaust heat-energy that is produced is also high than burning; 9) the high temperature burning is to carry out under negative oxygen condition, and the hydroxide that it produced reduces than burning significantly; What 10) the high temperature burning was adopted is closed recyclegas, and fuel gas is delivered to gas holder and propelling gas turbine engine, and combustion gas turns to flue gas with pernicious gas after gas turbine igniting reaction, therefore can accomplish need not smoke stack emission.Have characteristics such as equipment is simple, environment friendly and pollution-free.
