Description
Technical field
The present invention relates to a kind of dangerous waste incinerator, be specially down " U " shape two-section grate dangerous waste incinerator.
Background technology
At present, the burning type of furnace of burning hazardous waste mainly contains two kinds: rotary kiln type dangerous waste incinerator and pyrolysis oven formula dangerous waste incinerator.
The rotary kiln type dangerous waste incinerator, it is the burning mode that material is seethed in stove and move to the inclination angle end by the body of heater unitary rotation.The adaptability of this stove burning disposal hazardous waste is stronger, but this stove regulation and control difficulty is large, consume energy high, operating cost is high, maintenance cost is high.
Pyrolysis oven formula dangerous waste incinerator adopts the mode of burning again after the anoxycausis pyrolytic gasification.The advantage of this burning mode be the dustiness of tail gas and pernicious gas content all seldom, administer easily, operating cost is lower.But this stove can not be realized continuous operation, and the easy coking of slag is burned not exclusively, and operating environment is relatively poor during blowing out cleaning lime-ash.
For the incinerator mainly for the treatment of house refuse, also has the reciprocating fire grate stove, its structure mainly comprises reciprocating fire grate, air supply device, ignition combustion-supporting machine, spiral lime-ash gathering machine, screw type slag removing machine and feed arrangement, material enters into reciprocating fire grate from feed arrangement and burns, and the lime-ash after burning is discharged to the appointed place through lime-ash gathering-device and screw type slag removing machine.In combustion process, but Automatic continuous carry out, have the advantages such as automaticity is high, disposal ability is large, but this type of furnace can not directly be burned the hazardous waste of high heating value, high complexity.
Summary of the invention
The present invention seeks to the weak point that exists separately for above-mentioned incinerator, a kind of " U " shape two-section grate dangerous waste incinerator is provided, a kind of simple and reasonable, continuously-running, power consumption is low, operating cost is low, treatment effect can reach the hazardous waste incinerator special of international strict standard.Its technical characterstic is as follows: the self-movement separately of front and back two-part reciprocal grate, can effectively adjust the time of staying of different material in stove, and realize material completing combustion; A wind multi-wind-chamber segmentation cloth wind mode makes air distribution more reasonable, is conducive to the separating out and fully burning of pyrolysis, fugitive constituent of material; " U " shape design of falling of the second combustion chamber has extended the time of staying of flue gas in the furnace high-temperature section; The spray ammoniacal liquor air-washer of the second combustor tail can make the high-temperature flue gas more than 1100 ℃ be cooled to rapidly below 800 ℃, makes particle, salt, nitrogen oxide and acidic materials in flue gas be cut down in advance before entering exhaust gas processing device and control.
" U " shape two-section grate dangerous waste incinerator that falls is to take following skill technical scheme to realize:
The two sections grate-type dangerous waste incinerators of " U " shape that fall comprise down " U " shape the second combustion chamber, the first combustion chamber, overfiren air port, feed hopper, material pushing body feeder, front chimney arch, leading portion reciprocal grate, rear chimney arch, back segment reciprocal grate, wind separating chamber, a double ram type mucking machine, spray ammonia air-washer and ash dropping hopper.Described the first combustion chamber, leading portion reciprocal grate, back segment reciprocal grate, front chimney arch, rear chimney arch, a wind separating chamber are arranged on lower portion of furnace body; The double ram type mucking machine is arranged on bottom of furnace body; Falling " U " shape dual firing chamber, overfiren air port is arranged on upper of furnace body; The material pushing body feeder is arranged on the body of heater front portion; Spray ammoniacal liquor air-washer and ash dropping hopper are arranged on the body of heater rear portion.
" U " shape two-section grate dangerous waste incinerator is reasonable in design in the present invention, compact conformation, and due to two-part reciprocal grate before and after adopting, the fire grate air feed adopts the multi-wind-chamber even distributing wind, makes discarded object in stove inner drying, gasification and fully burns.Because the design of " U " shape is adopted in the second combustion chamber, the bags is large, and gas residence time extends, sufficient combustion; The mode that the double ram type mucking machine adopts upper and lower flashboard to open is alternately discharged slag, and system sealing is good, cannot not slag tap stifledly, without corrosion; The second combustor tail is provided with spray ammoniacal liquor air-washer, can make particle, salt, nitrogen oxide and acidic materials in flue gas be cut down in advance before entering exhaust gas processing device and control.
Description of drawings
The invention will be further described below with reference to accompanying drawing:
Fig. 1 is incinerator structural representation of the present invention.
The specific embodiment
With reference to accompanying drawing 1, the two sections grate-type dangerous waste incinerators of " U " shape that fall comprise down " U " shape the second combustion chamber (1), the first combustion chamber (2), overfiren air port (3), feed hopper (4), material pushing body feeder (5), front chimney arch (6), leading portion reciprocal grate (7), rear chimney arch (8), back segment reciprocal grate (9), a wind separating chamber (10), double ram type mucking machine (11), spray ammonia air-washer (12) and ash dropping hopper (13).Described the first combustion chamber (2), leading portion reciprocal grate (7), back segment reciprocal grate (9), front chimney arch (6), rear chimney arch (8), a wind separating chamber (10) are located at body of heater (14) bottom; Double ram type mucking machine (11) is arranged on bottom body of heater (14); Falling " U " shape dual firing chamber, overfiren air port (3) is arranged on body of heater (14) top; The material pushing body feeder is arranged on body of heater (14) front portion; Spray ammoniacal liquor air-washer and ash dropping hopper are arranged on body of heater (14) rear portion.
