Abstract
The invention discloses a reverse-operated waste incinerator hearth, which comprises a left side wall, a right side wall, a front wall, a back wall and a grate at the bottom; wherein a waste inlet is provided with the lower part of the front wall and a slag outlet is provided with the lower part of the back wall; the front wall and the horizontal plane form an included angle Theta 1 of 10 degree - 15 degree; the back wall comprises two integrated parts, with the lower part forming an included angle Theta2 of 38 degree - 48 degree with the horizontal plane. With optimization of the included angles formed between the front wall of the hearth and the horizontal plane as well as between the back wall of the hearth and the horizontal plane, the internal surface of the furnace mantle enables better radiation upon the drying zone and the combust zone during waste incineration. The reverse-operated waste incinerator hearth has the advantages of faster waste drying speed, combust promotion, shortened combust time for waste inside the furnace, partially increased processing capacity of the furnace and more stable combust inside the furnace. Temperature of flue gas is increased by 20-50 DEG C based on the original; the highest temperature of the outlet of a gas chamber can reach 1200 DEG C, thus the reverse-operated waste incinerator hearth has further advantage of lower incomplete combust rate for slag at the bottom of the furnace.
Description
Technical field
The present invention relates to a kind of incinerator burner hearth, particularly a kind of fire box of inverse push type destructor.
Background technology
The urban garbage disposal mode adopts mainly contains three kinds of processing modes such as sanitary landfills, During High-Temperature Composting and burning.Sanitary landfills, During High-Temperature Composting are because floor space is big, secondary environmental pollution, and its usage ratio is fewer and feweri.But the burning disposal that turns to final processing target with innoxious, resource, decrement obtains high speed development all the more, makes the incineration technology of domestic waste obtain to use widely.The technical characterstic of burning disposal is: subtract and hold remarkable, the innoxious degree height of effect; Burning disposal facility floor space is little, and surrounding environment is not had secondary pollution; Higher at refuse thermal value, handle when reaching certain scale, can also utilize its cogeneration or heat supply.The burning disposal mode can realize full out, to greatest extent that solid waste is innoxious, stabilisation, minimizing, large-scale treatment system also has energy recovery and use device, make that it is turned waste into wealth, waste and old utilization reclaims the energy, become the environmental protection main flow of garbage disposal.Therefore, the city economically developed, that refuse thermal value is higher, therefore the processing of adopting advanced incineration technology to carry out municipal refuse is optimal selection and investment.Incineration treatment of garbage technology and equipment reach its maturity.The main flow garbage disposal is burned the type of furnace and comprised: dynamic formula incinerator, Martin furnace reciprocating machine grate furnace, LXRF series vertical rotating kiln incinerator, fluidized bed incinerator etc. are thrown in the Basicl pulse.And the production technology of other supporting generating or heat supply and equipment all is similar as: waste heat boiler, steam turbine, flue gas desulfurization, water treatment system, electric, automatic control etc. basically, and very ripe.
Martin furnace reciprocating machine stove burning process is: after rubbish is shipped by garbage truck, be discharged in the garbage pool, garbage crane turns the rubbish that unloads, mix, and carry out the subregion storehouse, ferment, turn mixing and can make the component of rubbish even by the operation procedure of refuse pit, avoid the refuse thermal value of stove into fluctuated, thereby cause the excessive fluctuation of furnace temperature; The burning disposal that is suitable for Chinese rubbish.Rubbish enters fire grate (fire grate is divided into dry section, combustion zone, burning-out zone) under being tilted to by feed hopper, because the crisscross motion between the fire grate, rubbish is promoted downwards, (rubbish enters into another when district by a district by each zone on the fire grate successively to make rubbish, play an effect of standing up greatly), discharge burner hearth until after-flame.Combustion air enters from the fire grate bottom and mixes with rubbish; High-temperature flue gas produces vapours by the heating surface of boiler, and flue gas also obtains cooling simultaneously, and last flue gas is discharged after flue gas processing device is handled.
In the prior art, rubbish all is to burn in order at dry section, combustion zone, burning-out zone by fire grate in the Martin furnace burner hearth, because Chinese rubbish ins and outs, moisture is more, can cause at corresponding regional drying or incomplete combustion, make rubbish after-flame fully, lime-ash includes unburned rubbish, influences the garbage utilization rate.If reach the after-flame purpose, then need increase rubbish time of staying in burner hearth, cause efficiency of combustion to reduce, reduce the disposal ability of incinerator, influence the working stability of incinerator.
Therefore, need a kind of fire box of inverse push type destructor be transformed, can make the fully dry and burning of the rubbish that enters burner hearth, shorten the clean-burning time of rubbish, improve the garbage utilization rate, improve incinerator temperature and power efficiency, improve the disposal ability of incinerator, increase the incinerator job stability.
Summary of the invention
The object of the present invention is to provide a kind of fire box of inverse push type destructor, can make the fully dry and burning of the rubbish that enters burner hearth, shorten the clean-burning time of rubbish, improve exit gas temperature, improve the garbage utilization rate, improve incinerator temperature and power efficiency, improve the disposal ability of incinerator, increase the incinerator job stability.
Fire box of inverse push type destructor of the present invention, the fire grate that comprises left and right side wall, front wall, back wall and bottom, described rubbish import is arranged on the front wall bottom, the lime-ash outlet is arranged on the Hou Qiang bottom, the angle theta 1 of described front wall and horizontal plane is 10 °-15 °, described back wall is divided into the two parts up and down that are connected as a single entity, and the angle theta 2 of lower part and horizontal plane is 38 °-48 °.
Further, the angle theta 3 of described Hou Qiang top and horizontal plane is 102 °-110 °;
Further, the angle theta 3 of described Hou Qiang top and horizontal plane is 104 °;
Further, the angle theta 1 of described front wall and horizontal plane is 13.5 °;
Further, the lower part of described back wall and the angle theta 2 of horizontal plane are 42 °;
Further, two parts area ratio is 2: 1.2 about the described back wall.
Fire box of inverse push type destructor of the present invention, by optimization to burner hearth front wall and back wall and horizontal plane angle, make the furnace shell inner surface carry out heat radiation to going into stove rubbish better, accelerate to go into stove rubbish and carried out drying rate, promote the burning of rubbish, shortened the burning time of rubbish in stove, part has improved the disposal ability of incinerator, the burning of incinerator is more stable, and flue-gas temperature has improved 20-50 ℃ on the original basis, and a smoke-box outlet temperature is up to 1200 ℃, effectively improve the garbage utilization rate, improve incinerator temperature and power efficiency, increase the incinerator job stability, reduce furnace bottom lime-ash uncombusted rate; The top of back wall and lower part are respectively horizontal by different angles, heat radiation can be carried out to the rubbish of burner hearth porch in top, carries out preliminarily dried, for next step drying and burning creates conditions, further make incineration firing abundant, improve incineration firing speed; Back wall two parts area ratio up and down is 2: 1.2, thermal radiation effect the best.
