The specific embodiment

Provide as accompanying drawing, this incinerator by the burning body of heater that places the bottom and place in the middle of the oven dry body of heater and place the thermal-arrest body of heater three parts on top to constitute.This three part can be Integratively formed in when construction, also can adopt the each several part construction technology of assembly unit again after the moulding respectively.Incinerator body portion in its three part includes the burning fire grate 1 of horizontal in the body of heater bottom, the front portion of this burning fire grate dispose the exit be provided with adjust flashboard 17 on coal bunker 16, and be configured to the coaling machine 18 of coal bunker coal, the rear end fit beneath of burning fire grate is useful on the slag remover 3 that the lime-ash after the burning is transported out, place the combustion chamber 2 of burning the fire grate top to surround by furnace wall and covering arch, it covers to encircle is arranged to the low askew arch in preceding high back, and the opening that the front end of arch and furnace wall constitute is the passage of combustion product gases rising and rubbish whereabouts.The drying oven body portion comprises the oven dry fire grate 4 of horizontal on the combustion chamber covers arch, be provided with rubbish material bin 5 in the front upper of drying fire grate relatively, be provided with material bin removable cover 6 above this rubbish material bin, the discharging opening place of drying fire grate at material bin relatively disposes pan feeding adjustable plate 7, above the rear portion of drying fire grate relatively, surround drying chamber 8 by furnace wall and covering arch, the top of its drying chamber is provided with steam floss hole 9, this steam floss hole is communicated with steam trap 21 and air blast 20 through pipeline, and be connected in the combustion-supporting air port 22 of burning the body of heater bottom through the air outlet of air blast 20, on covering arch, drying chamber surrounds secondary combustion chamber 14 by furnace wall and covering arch, the mouth that advances of its secondary combustion chamber is opened in the rear end that drying chamber covers arch, and configuration second-time burning wind-supplying mouth 15, the outlet flue of secondary combustion chamber is opened in the opposite side that advances mouth relatively.The thermal-arrest oven body part comprises the heat collecting chamber 10 that is surrounded by furnace wall and furnace roof that places secondary combustion chamber top, the smoke inlet of its heat collecting chamber is the outlet flue of secondary combustion chamber, the fume emission mouth of heat collecting chamber is opened in the opposite side of relative smoke inlet, and can install fume temperature regulator 13 additional at its fume emission mouth place, be used for adjusting the flue-gas temperature that enters cleaner and air-introduced machine, in the heat collecting chamber of thermal-arrest body of heater, be provided with air preheater 12, the air inlet 25 of its air preheater connects air blast 19, gas outlet 24 connects oven dry air port 23 that places oven dry body of heater bottom and the second-time burning wind-supplying mouth 15 that places the secondary combustion chamber place, heat supply pot body 11 also can be set in heat collecting chamber, be used to provide hot water and steam.Its air preheater adopts horizontal thermal-collecting tube structure in the specific implementation, and heat supply pot body adopts vertical thermal-collecting tube structure, is beneficial to filter the suspension in the flue gas, plays better dust removing effects.

During the work of this incinerator, open the removable cover above the rubbish material bin, and adjust the pan feeding adjustable plate and place the appropriate location, after the rubbish that needs are handled drops into hopper, start the oven dry fire grate, the rubbish thing is deposited on the oven dry row according to certain thickness requirement.Ignite in the coal seam that will burn on the fire grate then, start air-introduced machine and air blast and adjust air quantity, make and be negative pressure state in the Burning Room, be barotropic state in the drying chamber, close the overfiren air port air door afterwards, wait to burn coal combustion on the fire grate stable after, start the oven dry fire grate once more, pending rubbish is sent into the burning fire grate to be burned, the hot blast that its rubbish has been produced by air preheater before burning is dried, and the water vapour that produces in the drying course is sent in the steam trap by pipeline, and condensed water is discharged into the fixed location and handles, gas (foul smell) burns with sending in the Burning Room once more after air mixes, and is purified.Combustion product gases of this incinerator and rubbish pan feeding adopt same passage, can make more inflammable rubbish thing fall into burn fire grate before just with flue gas together enter second-time burning indoor with mend by the second-time burning air port into hot blast be fully burned, the efficient of incinerator disposal of refuse is improved, the flue gas that is risen by Burning Room is further purified, and improve the collecting efficiency of heat collecting chamber.The relative rotation speed of burning fire grate of this incinerator and oven dry fire grate can be by the frequency-changing control system adjustment, and input amount coal-fired by the adjustable plate control of the adjustment flashboard of last coal bunker and rubbish material bin and rubbish, and the proportional quantity that guarantees coal-fired and rubbish is at suitable state.The air intake vent of its air blast and each air compartment disposes the air inlet adjustment plate, can control the size of required air quantity, guarantees that incinerator is operated in stable abundant fired state.
