Abstract
A household garbage continuous incinerator is characterized in that an air distribution chamber with an air supply hole opening rate of 20-30% is arranged at the lower portion of a furnace body, a ribbed heat-resistant cast iron circulating grate with an air hole opening rate of 15-20% is arranged at the upper portion of the air distribution chamber, two parallel roller dragging chains are connected to two sides of the grate, and a driving chain wheel of each dragging chain is arranged outside the furnace body. The furnace body feed hopper is provided with a closed hopper door, a slag outlet is provided with a movable baffle, and the lining is a heat-resistant cast iron plate. The method has the advantages that the flow direction and the flow velocity of the airflow are improved, the purposes of strengthening combustion, ensuring the furnace temperature and stably operating are achieved, and the incineration rate of the unit grate area can reach 0.25-0.35 cubic meter per square meter per hour. Is suitable for the incineration of household garbage.
Description
The utility model belongs to the device that destroys by fire of refuse, particularly a kind of urban domestic garbage incinerator.
Domestic waste quantity is various, and a large amount of house refuse outward transports and processing are all arranged every day, and the work of treatment amount of rubbish is very big.Usually adopt simple landfill method to destroy rubbish, but can't reach needs.Burning method is the principle that adopts pyrolysis, coking, can make organic matter rich in the house refuse at high temperature by destructive distillation, coking and thermal decomposition, produce solid carbon and fuel gas and carry out spontaneous combustion, lime-ash in the rubbish can be become the slag building materials by high temperature sintering, than the landfill method disposal of refuse more advantages are arranged, therefore be applied.Existing incinerator has vertical heater, multi-cavity stove, fluid bed furnace or kiln, because the difference of combustion system, the burning oxygen supply deficiency that has can not guarantee thoroughly burning fast of rubbish; Perhaps continuous feeding and discharging not, and make disposal ability limited; Also or the combustion chamber imprecision, the flue gas retention time is short, handles not thorough to flue gas.
The purpose of this utility model is, designs a kind of horizontal chained transmission incinerator, adopts heat-resisting cast iron fire grate with ribbing and distribution plenum, improve combustion chamber feed inlet and outlet seal, stable to guarantee furnace temperature, overheavy firing, burn continuously and deslagging, reach the purpose of efficient processing domestic waste.
Domestic garbage continuous incinerator of the present utility model, form by body of heater, combustion chamber, chimney, it is characterized in that, the distribution plenum of the wide open porosity 20～30% of air vent is established in the body of heater bottom, distribution plenum top is provided with the heat-resisting cast iron circulation fire grate with ribbing of ventilation holes percent opening 15～20%, the fire grate both sides are connected with two parallel roller entrainment chains, and the drive sprocket of entrainment chain is arranged on the body of heater outside;
The feed hopper of body of heater front upper part is provided with airtight sluice gate, and the slag notch at body of heater rear portion is provided with sideboard, and building the wall of body of heater and the liner of bell top board by laying bricks or stones is the heat-resisting cast iron plate.
Using method of the present utility model is, at the fire grate front end ignition substance is set, after can adopting various thermals source that ignition substance is lighted, start material loading machinery, add a certain amount of house refuse by feed hopper, after treating that rubbish point is burning, restart chain circulation fire grate, move continuously with 4～6 meters speed per hour; The rubbish addition should adapt with fire grate speed, and thickness of feed layer is remained on 1.5～2.0 meters, thereby realizes once igniting, continuous charging, the burning process of continuous pyrolysis.Distribution plenum air feed pressure increases to 4～5KPa by the 2KPa of general incinerator under the circulation fire grate, with overheavy firing, improves quantity combusted.Rubbish is behind the ignition belt of distribution plenum, main combustion band and burnt-out zone top primary reformer row's range ability, finish destructive distillation, pyrolysis, plain after-flame stage of charcoal, at the afterbody of air feed not, the slag that generates is after suitably lowering the temperature on the fire grate, pass the sideboard of slag notch, discharge out of the furnace, be transported to the concentrated area by mucking machine.
The utility model has the advantages that: adopt the distribution plenum of certain percent opening, can improve air flow direction and flow velocity, reach the purpose of overheavy firing; Employing has the heat-resisting cast iron circulation fire grate with ribbing of certain percent opening, can further improve air-flow and flow velocity, and is indeformable under heat run, guarantees incinerator operation steady in a long-term, reduces cost and reduces maintenance load; Adopt roller entrainment chain in geosyncline, to move, can guarantee that running steadily; Airtight sluice gate and sideboard are set, have improved the seal of combustion chamber, can guarantee furnace temperature; Simple in structure, cheap, reliable.On the per unit grate area, the house refuse of 0.25～0.35 cubic meter that per hour can burn.Be applicable to the continuous burning disposal of domestic waste.
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the domestic garbage continuous incinerator organigram;
Fig. 2 is the B-B profile of Fig. 1;
Fig. 3 is the plane of distribution plenum;
Fig. 4 is the profile of distribution plenum;
Fig. 5 is a heat-resisting cast iron circulation fire grate plane with ribbing;
Fig. 6 is a heat-resisting cast iron circulation fire grate profile with ribbing.
As seen from the figure, domestic garbage continuous incinerator of the present utility model, form by body of heater 1, combustion chamber 2, chimney 3, it is characterized in that, the body of heater bottom is provided with the distribution plenum 4 of the wide open porosity 20～30% of air vent, distribution plenum top is provided with the heat-resisting cast iron circulation fire grate 5 with ribbing of ventilation holes percent opening 15～20%, and the fire grate both sides are connected with two parallel roller entrainment chains 6, and the drive sprocket 7 of entrainment chain is arranged on the body of heater outside;
The feed hopper of body of heater front upper part is provided with airtight sluice gate 8, and the slag notch at body of heater rear portion is provided with sideboard 9, and building the wall of body of heater and the liner of bell top board by laying bricks or stones is heat-resisting cast iron plate 10.
