Background technology
The structure of well-known ， dioxin is that one or two oxygen combine two by the substituted phenyl ring of chlorine, so its generation must possess two conditions: the one, the existence of chlorine is arranged; Another is that oxidizing reaction takes place.Composting can have chlorine to exist, and burning is an oxidizing reaction, so waste incineration just in time meets two conditions that produce dioxin, in view of the above it can be asserted that: waste incineration unavoidably can produce Dioxins; Waste incineration produces a large amount of waste gas simultaneously, is discharged in the air the Greenhouse effect of contaminate environment, the aggravation earth; Atmosphere and surrounding environment are produced serious influence, receive coming down hard upon of the masses.Simultaneously, waste incineration investment is big, and running cost is high, and maintenance cost is high, makes the government in general city hold and can't stand, promotes difficulty, causes many cities to form garbage-surrounded cities, leads to the rubbish crisis.
We adopt the domestic refuse retorting technique to handle domestic refuse, the generation that can stop dioxin fully in the past.Because destructive distillation is the decomposition reaction of solid organic matters under the secluding air state, even there is chlorine to exist, does not have oxygen, oxidizing reaction does not take place can not produce dioxin yet; And then burning carbide (or inflammable gas), then, can not produce dioxin because there is not the existence of chlorine yet.This technology is just in time basic identical with the production technique of two stage type gas generating furnace, but the small scale of producer gas generator can only be used for the processing of day processing 100 tons of following domestic refuses; This just can not adapt to the actual needs of garbage treatment; The actual needs of big city domestic rubbish disposal particularly, for example Shanghai daily output rubbish is 20000 tons, 18400 tons in Beijing daily output rubbish; So require refuse treatment plant to maximize, the waste incineration field of 3000 tons of day processing is being set about building in Beijing.
The object of the present invention is to provide a kind of theory that can fundamentally stop to produce dioxin according to us about the rubbish destructive distillation; Utilize the substruction of producer gas generator to transform, innovate; A kind of novel, high-level efficiency is provided and can adopts the unit combination mode; The difference of processing power as requested, the synthetic daily handling ability of respective sets is at the large-scale domestic refuse destructive distillation-vapourizing furnace of 100-1000 ton (more than reaching); Both realize the discharging of the no dioxin of refuse treatment, non-exhaust emission, and satisfied the domestic refuse destructive distillation-vapourizing furnace of demand of the maximization of refuse treatment plant.
Summary of the invention
The present invention transforms, innovates on the basis of two stage type gas generating furnace, provides a kind of and is divided into a plurality of standard destructive distillation processing units to domestic refuse destructive distillation-vapourizing furnace, according to the needs of different treatment ability, is combined into large-scale domestic refuse destructive distillation-vapourizing furnace; Standard destructive distillation processing unit makes the producer gas generator cylindrical furnace into cube, sealing body of heater, is convenient to a plurality of processing units of assembly unit, realizes maximizing; Standard destructive distillation processing unit top is provided with the retort section and the dryer section of rubbish; Utilize rubbish to be under the anaerobic state earlier the rubbish destructive distillation; Decomposite inflammable gas (being referred to as " dry distillation gas ") and carbide residue; Carbide below burning produce high temperature, make vaporized chemical with water vapor and air, the carbide under the condition of high temperature is the CO of burning generation
2And water vapour (H
2O) reduction generates semi-water gas (CO, H
2And N
2Deng, can be referred to as " gasification gas "), the pyritous gasification gas the heating of the rubbish of retort section, makes rubbish destructive distillation (decomposition reaction) in the process of rising, and gasification gas continues to rise, heats the rubbish of dryer section, dry; Collect dry distillation gas and utilize, thereby both realized that domestic rubbish disposal do not have dioxin discharging, non-exhaust emission with gasification gas, realize again maximization built-up type domestic refuse destructive distillation-vapourizing furnace.
The technical scheme that the present invention solves its technical problem is:
The technical scheme of technical solution problem of the present invention is: be divided into a plurality of standard destructive distillation processing units to domestic refuse destructive distillation-vapourizing furnace, and the difference of processing power as required, respective sets is synthesized large-scale domestic refuse destructive distillation-vapourizing furnace; Each standard treated unit adopts cube and sealed structure, is convenient to a plurality of standard treated stove of assembly unit simultaneously unit, forms large-scale domestic refuse destructive distillation-vapourizing furnace, as the pit kiln of steel mill, realizes that refuse treatment plant maximizes; Each standard treated unit is inner, the pipe core of original cylindrical producer gas generator, changes the middle comb of the row of putting in order, and becomes symmetric left and right sides two portions to the standard treated unit separation; In order to let rubbish effectively heat, the width of every part rubbish generally is advisable at 1-2 rice; The top is provided with the retort section and the dryer section of rubbish; Utilize rubbish to be under the anaerobic state earlier the rubbish destructive distillation; Decomposite dry distillation gas and carbide residue; Carbide below zone of combustion burning produce high temperature, make vaporized chemical with water vapor and air, the carbide under the reducing zone condition of high temperature is the CO of burning generation
2And water vapour (H
2O) reduction generates gasification gas (CO, H
2And N
2Deng), for the rubbish of rubbish retort section provides the heating heat, decompose by the rubbish destructive distillation in the process that rises for the pyritous gasification gas, rises to the drying garbage section again and make rubbish heating, oven dry; In addition; Because the ventilation property of rubbish and carbide is bad; The resistance that scorching hot gasification gas sees through carbide and waste layer rising is bigger; Cause directly to obtain to heat heat from gasification gas and can't make the abundant destructive distillation of rubbish, drying, and because gasification gas rise obstructed, wherein reducing gas CO, N
2Be detained, the carbide burning is just not vigorous, the combustionvelocity of slowing down carbide; Thereby reduce the efficient of refuse treatment, for this reason, handle the unitary retort section of stove in the standard destructive distillation; Specially around with middle the high-temperature fuel gas chamber is set, the inwall of high-temperature fuel gas chamber has ventilation hole, dry distillation gas is through these ventilation holes entering high-temperature fuel gas chamber; Mix, pool together with gasification gas; The high temperature (more than 600 ℃) that relies on combustion gas makes the tarry vapours in the dry distillation gas produce cracking, generates micromolecular combustion gas; Heat the rubbish that is clipped in the middle through radiation fully destructive distillation simultaneously; In dryer section the combustion gas ventpipe is set, guiding gas (comprising gasification gas and dry distillation gas) rises; The breathing area of high-temperature fuel gas chamber is bigger than combustion gas ventpipe, so combustion gas is long in the high-temperature fuel gas chamber residence time, and rubbish is by fully heating, destructive distillation; And flow velocity is low, and the flue dust that is mixed in the gasification gas also drops, and plays dust separating effect; High-temperature fuel gas rises to dryer section from the combustion gas ventpipe, makes rubbish heating, drying; The water vapor that drying garbage produces must leave as early as possible, otherwise rubbish just can not get into the destructive distillation state, influences the processing efficiency of rubbish, for this reason; The escape pipe of water vapor is set between two combustion gas ventpipes, also has logical steam vent, the water vapor that drying garbage produces gets into water vapor hole escape pipe through ventilating pit, and fast rise arrives furnace roof; Because water vapor is not detained, and can leave rubbish flash baking as early as possible; Get into retort section, carry out decomposition reaction, so processing efficiency improves; At last, collect dry distillation gas and gasification gas, can carry out various utilizations; Drying garbage has consumed a large amount of vaporization heat, and the water vapor of generation also is a useful resource, can be in order to being used as vaporized chemical.
The invention has the beneficial effects as follows:
1, do not produce Dioxins
Waste incineration unavoidably can produce Dioxins.Rubbish is first in following rubbish destructive distillation of secluding air state in destructive distillation-vapourizing furnace, because there is not oxygen just can not produce dioxin; And then the combustion carbide, do not have chlorine to exist and can not produce dioxin yet.This is that the rationale that does not produce dioxin is handled in the rubbish destructive distillation.In fact, because the organism in the rubbish all changes clean gas into, all collect and utilize, discharging does not have dioxin naturally.
2, do not have exhaust gas emission, do not have smokestack, do not pollute
Waste incineration per ton will produce the waste gas of 4000-7000 cubic meter, constitutes the severe contamination of air and having a strong impact on of weather.Particularly the high temperature of waste incineration generation generates NOx and SOx, and is more serious to the influence of environment.Utilize domestic refuse destructive distillation-vapourizing furnace treating refuse, waste gas CO
2Be taken as the utilization of resources, do not have exhaust gas emission, do not constitute pollution environment.
3, rubbish need not classification
Domestic refuse destructive distillation-vapourizing furnace treating refuse, rubbish need not classification.Waste incineration needs refuse classification in order to suppress the generation of dioxin.This needs broad masses' cooperation, and the whole people take action and carry out refuse classification from the source.But China does not carry out the custom of refuse classification; Also need carry out separate waste collection, classification transportation, classification processing, increase many inputs.
4, realize real waste reductionization
The past people have unilateral understanding for minimizing: think that waste incineration is fallen, " eyes cannot see " is exactly minimizing.In fact conservation of matter, we can not " burn rubbish not had ", but become waste gas; Volume is big, and damaging range is wide, refers to that the physical form of rubbish changes: eliminated depleted rubbish; Convert useful clean gas to, the waste reductionization that this is just real.
5, also use, realize unique resource utilization to waste gas
The refuse treatment combustion of organic matter produces a large amount of waste gas, in the present invention the CO in the waste gas
2Also be used as resource, be reduced into CO to it and recycle, this is unique garbage as resource utilization.
6, unit combination realizes that refuse treatment plant maximizes
The past waste incineration unavoidably can produce Dioxins, and many treatment of urban garbage reconnaissances are difficulty very, thus require to maximize, to satisfy the needs of refuse treatment.And grate furnace in the past can't be realized maximizing, and investment is big, and popularization is restricted.The present invention can get up the fixed grate unit combination according to actual needs, constitutes large-scale grate furnace, can satisfy metropolitan demand, helps to crack the rubbish crisis.
7, overcome the difficult problem that the refuse treatment investment is big, running cost is high, maintenance cost is high
Garbage incinerating system is complicated; Need spend substantial contribution to carry out waste gas pollution control and treatment, flying dust disposal during processing; Cause the investment of refuse treatment big, running cost is high, maintenance cost is high, the government burden in general city and small towns does not rise, and becomes the hang-up that perplexs governments at all levels.The utilization of domestic refuse biological fuel gas overcomes this difficult problem fully.
8, energy-saving and emission-reduction are remarkable especially, can carry out the carbon transaction
The past garbage loading embeading produces a large amount of greenhouse gases, mainly is methane, and its Greenhouse effect are also stronger 21 times than CO2.The whole world is in order to tackle climate warming, and United Nations repeatedly holds the energy-saving and emission-reduction meeting.The discharging of methane is avoided in domestic refuse destructive distillation-vapourizing furnace treating refuse fully; Simultaneously, clean gas can replace fire coal, saves CO again
2Discharging, can carry out carbon transaction (CDM), betray the carbon index, obtain abundant additional income.
9, clean gas can have multiple application
The recycling of waste incineration can only do cogeneration, and waste incineration and generating electricity at first needs a large amount of investments, and it is more much more than the power station investment of building a same power generation capacity to build a garbage incinerating power plant; Secondly, the inefficiency of waste incineration and generating electricity has great amount of heat to run away with waste gas; The efficient of waste heat boiler and steam turbine is low; The 3rd, day treatment scale is at the small-scale garbage incinerating power plant below 200 tons, and economic benefit is low, is difficult to recoup the investment, and is not suitable for building garbage incinerating power plant and has become common recognition; The 4th, garbage incinerating power plant is produced unstable, the online difficulty.The present invention converts rubbish into clean gas, can directly supply domestic gas, or provides Industrial Boiler to use; It is higher also to can be used for fuel gas generation efficient, higher than the efficient of waste incineration and generating electricity; More can be used for baking bricks, consume the inorganics in the rubbish simultaneously; Can also carry out synthetic.All these can obtain other income, and refuse treatment becomes profitable new forms of energy.
