The output of vivid rubbish of our country city already amounted to 260 million T, still increase by degrees with 7% right-and-left speed, the city life rubbish that grow day and day has become a worry the social problem that dweller of environment of city of urban progress, pollution, influence lives. Fill traditionally bury, the demand that the rubbish such as compost handles craft to cannot have satisfied daily rubbish to handle, effective implementation rubbish is decreased quantify, harmless change and the rubbish that resource changes burns processing technology is the first selection plan that solves problem of rubbish encircle a city at present. My company is mixed to the current situation of rubbish incinerator furnace had a technology analysis and advantage are analytic.
Rubbish of type of mechanical furnace platoon burns generate electricity the technology has treating capacity big, moving reliability cycle of taller, processing is short, decrease quantify remarkable, harmless change complete and can reclaim rubbish burns the advantage such as more than heat, appropriate large-scale processing is worth city life rubbish without classified high fever. The rubbish of many 2300 life that already built in the whole world burns in power plant, mechanical incinerator utilization rate is in 80% above, it is at present rubbish of domestic and international city life burns generate electricity the optimal processing means of processing.
Mechanical furnace platoon burns technical traceable Europe and United States, burn in rubbish the domain gets be usinged extensively, the main oven that already made rubbish burn, through be being accumulated for years, the largest treating capacity has reached odd desk 1200 T/d. 3 water chestnut companies of German horse man and Japan, day establishs shipbuilding and rice of German Si Tan to strap company, Belgian Xigesi to burn generate electricity the technical level of equipment all locates alive bound front row, its product has rate of combustion stability, automation the characteristic with tall, sufficient combustion.
Domestic production makes mechanical furnace platoon burn generate electricity the proprietor of an enterprise of equipment should have Chongqing 3 peaks, smooth big international and green motivation, but dimensions of processing of only station incinerator is relatively lesser, and combustion effect is very not ideal. Rubbish of class of above of domestic large kiloton burns power plant is given priority to with introducing foreign technology and device, need costs a large number of foreign currency to introduce the core device such as technology and rubbish incinerator, but facility cost reachs moving cost all taller, and its mix collection life rubbish to our country city the characteristic adaptability such as low calorific value, high-moisture is low.
Incinerator of instrument of large scale computer has sheet big, land occupies capability of product line processing garbage power of little, unit measures dosage tall, safeguard the good point with low cost, burn as rubbish generate electricity engineering technology progress and land natural resources are more and more precious, incinerator of rubbish of type of mechanical furnace platoon will forward large change, intelligence is changed and efficient the way that change develops.
Mechanical furnace discharges type incinerator to use a layer to light a technology, with the furnace of mechanical platoon piece forms hearth, undertake rubbish direct combustion, the gravity of the opposite motion between furnace platoon and rubbish itself makes rubbish flips through ceaselessly, agitate is pushed go ahead, whole combustion process undertakes in a the chamber of a stove or furnace. Rubbish is entered above all dry paragraph, to assure rubbish can fast drying, dehydrate, use the air after heating to discharge bottom to undertake stoving to rubbish from furnace, at the same time rubbish of the combustion inside furnace also can is opposite dry paragraph rubbish undertakes roast; enters combustion when rubbish paragraph hind, rubbish undertakes in 900 ℃ left and right sides high temperature burns, can make among them can light composition and harmful composition to be decomposed thoroughly, at the same time hearth enters air to undertake cooling to furnace platoon, prevent what high temperature discharges to furnace to damage; to be entered when rubbish thereby light ashes paragraph hind, rubbish is in drop in temperature the process is lighted thoroughly, become grey broken bits completely, rubbish combustion is whole flow is finished.
The treating capacity that is only station furnace is large, the largest treating capacity has reached odd desk 1200t/d, apply to large-scale concentration to handle; of city life rubbish
2 it is rubbish adaptability tall, do not need warm-up, sorting and broken processing into makings rubbish, suit our country to did not classify; of collection life rubbish current situation
3 it is combustion condition stability, the mechanical movement that relies on furnace platoon comes true to churn and mix of rubbish, adjust the rubbish inside furnace to burn state and furnace platoon rotate speed, make rubbish distributings inside furnace even, makings layer is stable, control rubbish is in the retention period inside furnace, ensure rubbish burns adequately, flying ash amount is small, hot bright decreases rate low;
4 it is automation degree taller, the operation is simple, raised incinerator to run level of management and overhaul efficiency, equipment year run time≥8000 H;
5 it is moving cost low, rubbish burns on furnace platoon, and not mix into burns coal, content of the dust in flue gas is so low, reduced the burden of dust catcher, reduced moving cost.
It is investment cost is high, as a result of the activity furnace is discharged and the crucial part such as fixed furnace platoon is made by heat-resisting alloy steel, facility cost is so higher;
2 it is hot loss big, because combustion rate is slow, the negative charge of hearth is small, the volume of furnace is so larger, workshop area increases, the hot loss of body of heater increases; 3 it is rubbish calorific value the demand is high, below the circumstance of on the low side of rubbish calorific value, to maintain combustion, make sure parameter of vapour of more than heat boiler is reached accord with environmental protection requirement, need enters fuel to the gush inside furnace or burn gas, make moving cost elevatory.
Fundamental of flaming of incinerator of type of mechanical furnace platoon is roughly identical, it is to pass the motion that furnace discharges to drive life rubbish to retroflexion ceaselessly, forward or agitate is converse mobile. Discharge configuration to go up from furnace, the furnace that its can divide into the furnace platoon that by furnace platoon piece forms and hollow cylinder composition discharges the athletic formally that two kinds of; discharge from furnace, on the way that its can part into reciprocate and the furnace that scroll moves to discharge two kinds of; to move from rubbish, its can divide the direction that to go against the furnace that turn pattern the platoon, suitable furnace that turn pattern is discharged and; of platoon of multistage type furnace discharges motion from furnace to go up, its can divide platoon of furnace of the inclined that it is bend and; of platoon of horizontal type furnace to discharge an athletic form from furnace, its can be divided for action type furnace platoon and row move type furnace platoon. What apply at present is main have go against push model furnace platoon, suitable push model furnace platoon, platen furnace platoon, its are main the function is the mechanical movement that furnace platoon makes move back and forth, the movement that drives life rubbish thereby and retroflexion.
Incinerator of current and commonly used type of mechanical furnace platoon basically has tilt go against turn reciprocating type heat platoon, tilt suitable push move back and forth to list the furnace that use formula platoon, tilt suitable push move back and forth smooth-going of platoon of action type furnace, water turns reciprocating type heat platoon, tilt platoon of multistage type furnace.
Tilt the athletic way that goes against the rubbish in pushing platoon of reciprocating type furnace to point to rubbish combustion process and way of furnace platoon movement are opposite, before furnace discharges whole tall hind low, tilt decorate, working principle is shown 1 times like the graph.
Fixed furnace is discharged and mobile furnace platoon tilts with behavior unit crisscross is decorated, mobile furnace seniority to reciprocate, the rubbish on furnace platoon is down shift below gravitational action, and makings layer bottom suffers rubbish to tilt instead with gravitational direction thrust, make furnace of edge of one part rubbish discharges the surface to move toward opposite way at the same time, arose to move up, what finish rubbish layer from this is sufficient retroflexion, agitate, make rubbish and air are contacted adequately, realize the combustion with sufficient rubbish. Its advantage is rubbish retroflexions agitate capability is strong, cover an area of an area small, investment is little, defect is rubbish may agglomerate boil fall, combustion effect is differred slightly relatively.
Tilt the athletic way that arranges the rubbish in pushing move back and forth to list platoon of the furnace that use formula to point to rubbish combustion process and way of furnace platoon movement are same, before furnace discharges whole tall hind low, tilt decorate, working principle is shown 2 times like the graph. Furnace arranges fixed furnace platoon and activity to be decorated to crisscross, mobile furnace is arranged in around reciprocate while generation moves up and down, the fore-and-aft thrust that the reciprocate that the gravity of rubbish support oneself on furnace platoon and mobile furnace arrange produces to rubbish layer and cut force to keep to tilt direction flips through, each furnace discharges Duan Li to make with tall fall rubbish produces mixture mix, decide furnace to arrange a setting in combustion Duan Gu cut a knife, it is having the effect of sufficient agitate rubbish not only, and help combustion air and rubbish are contacted adequately, make rubbish combustion complete. Its advantage is furnace platoon area is large, bear adjustment capability is strong, rate of leakage broken bits is low, defect is to retroflexion agitate ability is poor, cover an area of an area big, investment is high.
Tilt the athletic way that arranges the rubbish in pushing platoon of reciprocating type furnace to point to rubbish combustion process and way of furnace platoon movement are same, furnace seniority is decorated to the level, whole tilts downward, working principle is shown 3 times like the graph. Fixed furnace is discharged and mobile furnace platoon is decorated with behavior unit crisscross, mobile furnace seniority to horizontal reciprocate, the horizontal thrust that the rubbish on furnace platoon forms pair of rubbish layers to arise in gravity and mobile furnace keeps below joint action to tilt direction flips through, through falling appoint rubbish produces mixture mix, what finish rubbish layer from this is sufficient retroflexion, agitate, make rubbish and air are contacted adequately, realize the combustion with sufficient rubbish. Its advantage is furnace platoon area is large, furnace discharges a load small, life is long, amount of leakage broken bits is small, defect is combustion efficiency difference, cover an area of an area big, investment is high.
The athletic way that water smooth-going pushs reciprocating type furnace to discharge the rubbish in pointing to rubbish combustion process and way of furnace platoon movement are same, furnace discharges integral level to decorate, working principle is shown 4 times like the graph. Fixed furnace is discharged and mobile furnace platoon is decorated with uptilt of behavior unit crisscross, mobile furnace seniority to tilt up reciprocate, the rubbish on furnace platoon drives next keeping that go up backward in what mobile furnace discharges direction flips through, agitate and carry, make rubbish and air are contacted adequately, realize the combustion with sufficient rubbish. Its advantage is to retroflexion agitate capability is strong, ventilated effect is good, combustion is even, defect is to carry ability difference, cover an area of an area big, investment is high.
Tilt furnace platoon points to multistage reciprocating type way of the athletic way of the rubbish in rubbish combustion process and furnace platoon movement is same, furnace seniority is decorated to the level, whole tilts downward, working principle is shown 5 times like the graph. The group of standard furnace platoon that it tilts by multistage is formed, group of platoon of every standard furnace is discharged by fixed furnace platoon, slip furnace and flip through to furnace discharges mutual union and be become. Slip furnace platoon drives rubbish layer to discharge extreme motion to furnace, and flip through furnace platoon makes rubbish becomes Peng loosens and fill air, keep below the joint action that the rubbish on furnace platoon discharges in slip furnace syncline lower part flips through, agitate and carry, make rubbish and air are contacted adequately, realize the combustion with sufficient rubbish. Its advantage is to retroflexion agitate capability is strong, control is quick, combustion effect is good, defect is to carry ability difference, cover an area of an area big, investment is high.
Go against rubbish of the incinerator that turn pattern to retroflexion agitate capability is strong, cover an area of an area small, apply to the processing of rubbish of high calorific value, low moisture content, good in Europe and result of Japanese rubbish classification nation market has rate tall; to arrange the incinerator that turn pattern bear adjustment capability is strong, cover an area of an area big, more apply to the rubbish current situation with poorer result of our country low calorific value, high-moisture, classification, if main technique contrast expresses 1 to show.
About incinerator of type of mechanical furnace platoon current situation of domestic and international technology is mixed development trend, analysed commonly used and mechanical furnace to discharge type incinerator main technique characteristic. Show level, mechanical furnace discharges type incinerator to present diversity to develop a tendency, each furnace discharges an enterprise to reach the need of the user according to the characteristic of rubbish itself, research and development gives the mechanical furnace of different type to discharge incinerator. In addition, the article still introduced commonly used and mechanical furnace to discharge the classification of incinerator, expatiatory tilt go against turn reciprocating type heat platoon, tilt suitable push move back and forth platoon of action type furnace, tilt arrange push move back and forth to list smooth-going of platoon of the furnace that use formula, water to turn reciprocating type heat platoon, tilt the working principle that the commonly used and mechanical furnace such as platoon of multistage type furnace discharges incinerator and technology, undertake technical analysis and contrast to its function, the design that this conduces to our country mechanical furnace discharging incinerator of type life rubbish, application, research and development and function are optimized etc.
Rubbish burns the place with the mainest processing is furnace liner, lining should be bumped not only by machinery, rubbish fluctuation, around moves erode, and be eroded even by the chemistry of material of rubbish of sex of different soda acid, it is good to because fireproof liner should choose this liner material,have sex of fireproof, wear-resisting, heatproof shake and fight erode the gender is strong, be able to bear or endure the fireproof stuff that eats material to pledge.
