Embodiment: a kind ofly change solid refuse into fuel or energy approach
The invention solves the problem in the low and garbage loading embeading soil of firing efficiency.Such effect is by with the rubbish charging apparatus, separates combustiblematerials and incombustible substance, removes the device of incombustible substance, and by under high-temperature and high-pressure conditions, combustiblematerials is converted into the relatively hard and frangible steps such as patch fuel realize.
This invention properly applies to principle of work described above in the reality.
According to this invention, such device comprises the device of a rubbish access, be used for a device that separates combustiblematerials and incombustible substance, a device of removing incombustible substance, a conversion system that under high-temperature and high-pressure conditions, combustiblematerials is converted into relatively hard and frangible patch fuel.
At last, this invention also relates to and adopts device of the present invention, the description of the prepared patch fuel of the method according to this invention.
The method that solid refuse is changed into fuel totally is divided into two stages, and these two stages recur, and wherein, the efficient of second stage depends on the quality that first stage reaches.
The fs of method of the present invention is that following three kinds of rubbish are reprocessed, that is:
I) domestic refuse (municipal garbage);
Ii) with respect to office's rubbish of domestic refuse;
Iii) material except domestic refuse of collecting;
These rubbish after regeneration as the basic material of the second step of method of the present invention.
The material except domestic refuse of collecting is comprised of rubbish and the plastic garbage of paper and similar paper mostly, all is considered to the rubbish of high calorie.
The subordinate phase of method of the present invention is that resulting material of fs is reprocessed, and makes it to be transformed into compression, stable and frangible patch fuel.
The Hard grove grindability index of these patch fuels is 51～53, and preferably 52, be taken as fuel and be used for modern high-level efficiency power house of burning coal.There is 40%～45% rate of combustion in these power house, and therefore, its efficient is 2 times of incinerator, and can reduce carbonic acid gas, nitride and other gas purgings that is harmful to health.In addition, incinerator is not to make for high calorie rubbish, and is too high because temperature of combustion can rise, may cause incinerator badly damaged.
The fs of method of the present invention comprises a series of step, as shown in Figure 1.
At first collect and store solids rubbish, then solid refuse be handled as follows:
The first step: solid refuse is ground into the fragment that particle diameter is 5～10cm.Can adopt hammer mill or shredder to pulverize, the kind (when for example pulverizing the again processing mixture of paper and plastics, can use shredder) that adopts which kind of equipment to pulverize to depend primarily on rubbish.
Second step: incombustible part (metal, glass, stone, sand etc.) is separated from waste flow, and it is feasible technically, also is economy and environmental protection.Can adopt strainer or sieve based on gravity to carry out lock out operation.Incombustible part is further separated at the following step, at first be the separation (utilize the density difference between metal and the remaining material and adopt flotation process) between metal and the remaining material, secondly be iron content and nonferrous metal between separation (metal trap or static separator).Therefore, for example can use dispersing apparatus: the magnet of setting and stream of plastic top, eddy-currents instrument etc.
The 3rd step: the humidity that controls environment is dewatered to solid plastic under 4～5% conditions.
Here available conveyor dryer carries out drying.Compare with rotary dryer, the advantage that conveyor dryer has is: the temperature during owing to drying is low, therefore can not produce volatile organic matter, and be difficult for catching fire when drying.Water is the form disappearance with water vapour.In this step, when dry, the salts solution of carrying secretly in the solid refuse changes crystal salt into, thereby is removed.Specifically can adopt porose stainless steel belt drying machine, porose Stainless Steel Band as sieve with salt crystallization filtering.When drying, the working medium of use is warm air, hereinafter, will specify the processing of the dry tail gas that produces.
The 4th step: with rough the sorting out of plastic flakes (for example the mode of hand-sorted or utilize density difference screening perhaps adopts the mode of pneumatic separation), remaining mainly is the pieces of biomass such as paper, wood, fiber.
The 5th step: when must produce biomass fuel, the pieces of biomass such as remaining paper, wood, fiber are carried out purifying in the 5th step behind the sorting plastic flakes, obtain 100% biomass.This that is to say, biomass part Economical Purification, at least also needing to be purified to 97%, inorganics is extracted.Such purifying has been arranged, and the incombustible substance of final residual has just thoroughly been separated, in the 5th step, the material that the 4th step obtained is toppled in the entry, inorganics can sink to the bottom, and the pieces of biomass such as paper, wood, fiber parts floats over the water surface on then, thereby makes the pieces of biomass purifying.
Also can be used as conventional oil after these plastics are separated and use, although this fuel is not to be present in biomass fully.
The biomass that obtain in the 5th step purification step will be used in subordinate phase after carrying out further homogeneous operation.
When must produce conventional oil, the pieces of biomass after the fs the 5th goes on foot the purifying that obtains mixes (the 6th step) with the plastic flakes that separates from solid refuse.This mixture has also added isolated plastic components when pieces of biomass purifies.The plastic flakes composition can not surpass 30% in the mixture uniformly, otherwise can not prepare frangible fuel.Plastic flakes behind mixing and the homogeneous and the mixture of pieces of biomass will obtain using at method second stage of the present invention.
Isolated plastic substance can be used as the starting material of producing petroleum products in the 4th step institute, goes on foot the plastics that obtain in the purification step the 5th and also can be used for producing petroleum products.
Subordinate phase in method of the present invention is that the material use mechanical means that the fs obtains is made its moulding, can use the single-lead-screw extruding briquetting machine of Denmark Tempress company, also can use the plastic extrusion forming machine of other kind.The Tempress single-lead-screw extruding briquetting machine is in particular municipal garbage and designs, and combustiblematerials becomes constant molecule and frangible fuel pellet.
The second stage of the subordinate phase of method of the present invention at first is the pure biomass of extrusion molding to the mixture behind the 6th homogeneous that obtain of step, the perhaps mixture behind pieces of biomass and the plastic flakes homogeneous); Then also to cool off the patch fuel of extrusion molding.(further be in the process of making pure components of biomass, can produce biological particles; Make at the mixture of making organism and plastics, will produce the conventional oil particle).After these steps of experience, the patch fuel material of extrusion molding can be by the extruding of carrying out again and cooling.
In the extrusion molding process, material is pushed and is tormented by the synkinesis of axle or main shaft on the Tempress single-lead-screw extruding briquetting machine.The temperature and pressure of material can rise to a very high level, because the material that the humidity of the material that is extruded (mixture of pure pieces of biomass or pieces of biomass and plastic flakes) will be pushed than usual is much higher.In the baking step of fs of method of the present invention, it is about 4%～5% that material humidity reduces to, and general situation is, humidity is 0.5%～1% during the plastic material extruding of extrusion molding.
The humidity of heating material can cause the significantly rising of pressure.In this process, the temperature that material reaches surpasses 200 ℃, is more preferably at 240～290 ℃; In fact, the temperature about 270 ℃ is proved to be the effect that can reach best.The symphyogenetic result of high temperature and high pressure is: the composition in the material is changed, and this can cause the decomposition of carbon molecule and the minimizing of carbonic acid gas.
Can know the material found out before the not extruding and the internal structure of the patch fuel after the extrusion molding by contrast electron-microscope scanning figure accompanying drawing 7 and accompanying drawing 8, accompanying drawing 7 is scanning electron microscope (SEM) photographs of the fuel before the not extrusion molding, and accompanying drawing 8 is scanning electron microscope (SEM) photographs of the patch fuel that makes of the present invention.Can learn after the contrast that in extrusion process the material that extruding obtains is the hard frangible and fully uniform particle of composition.
Do not add additive in the method for the present invention, the patch fuel that makes is stable, and the such additive of employed refinery coke of past is unallowed in many countries.
Compare with common single-lead-screw extruding briquetting machine, the Tempress single-lead-screw extruding briquetting machine is adapted at working in the situation of High Temperature High Pressure, and treatment capacity is large.
First step in the extrusion molding process, material are at first carried out degassed processing, may comprise volatile component in the gas of release, for example hydrocarbon polymer and muriate.The gas that discharges will be collected, and if necessary, waste gas will clean by water in cleaning device.Water soluble substance is sent to effluent treatment plant, the remaining volatile organic component that also contains, and it will be sent back in the burner of the 3rd step of fs belt drying equipment.
Because under the environment of high temperature, material has the danger of spontaneous combustion, and that is to say to become fuel, and extruding is (or fully ventilate, making so, property gas is diluted fast) that carries out under the environment of hypoxemia.Push simultaneously the material of output in process of cooling, still there is danger on fire in patch fuel owing to also be in the state of high temperature, therefore, still requires the environment (or the environment that fully ventilates) of hypoxemia.Tempress single-lead-screw extruding briquetting machine and cooling apparatus can also be arranged in the airtight environment, then in airtight environment, fill inertia, incombustible gas (those of ordinary skills are in order to prevent the burning of volatile organic matter, and that can think goes out these methods).In addition, at the cooling air that cooling segment uses, heating, also can be used as the drying medium in the drying step.
The heating energy of the patch fuel that method of the present invention makes and the heating energy of coal are basic identical, can be applied to the fuel-burning power plant, the heating energy of coal is approximately 20MJ/kg～28MJ/kg, and the heating energy of about 20MJ/kg～22MJ/kg is arranged according to the patch fuel of described method manufacturing.After claying into power in the ball mill, patch fuel can burn together with coal.Patch fuel can mix with wood substance grain simultaneously, can be used as the biofuel that burns the coal power generation station.
Derive from the rubbish calcareous in relatively many paper and the cardboard because the fuel agglomerate has comprised, thereby reduce the generation of sulphur in the coal combustion process.What therefore, patch fuel produced is clean burning.
