Wherein, described tempering tube and primary air intake pipe all are communicated with a main steam line outside stove.
Air compartment on the described fire grate lower surface can be provided with a plurality of, and can single-row setting or biserial setting.
Described body of heater top also can be provided with waste heat boiler; Be provided with adiabatic crown between described waste heat boiler and the incinerator.
Described waste heat boiler is provided with flue, air-returen flue and waste heat boiler smoke outlet flue, and water-intake pipe.
Also be provided with the bypass adjustment doors between the flue of described waste heat boiler and the smoke outlet flue.
The main feature of the internal combustion type domestic waste incineration of the utility model design is: adopt the internal combustion mode rubbish that ignites, improve the adaptability to ash content height, moisture content height, rubbish that calorific value is low; To the abundant air feed of the rubbish that has ignited, make its fierce burning, reach the flue gas of refuse burning temperature requirement; The stove vent has guide effect, is convenient to the rubbish that ignites bottom the rubbish bed of material; The grate surface upper forepart has tempering tube, is convenient to from the rubbish material layer lower part rubbish that ignites; High bed of material windrow does not stir in the burning process; Waste heat boiler and incinerator form integral body; Owing to be provided with the bypass adjustment doors, make part or all of flue gas flow directly into air and give hot device without waste heat boiler, the flue-gas temperature that makes the inflow air give hot device reaches 450 ℃, guarantee that preheated air temperature reaches 250 ℃, it is low excessively to avoid flowing into air League flag flue-gas temperature when opening stove, and the condensate water corrosion takes place.
The advantage of the internal combustion type domestic waste incineration of the utility model design is reliably to burn domestic ash content height, moisture content height, rubbish that calorific value is low; When burning away the refuse, need not add auxiliary fuel, operating cost is low, less than 30 yuan/ton; System is simple, and cost is low, is roughly equal to 100,000 yuan of/ton days; Simple in structure, easy to operate.
Further describe the utility model below in conjunction with drawings and Examples
The overall structure schematic diagram of the internal combustion type domestic waste incineration that accompanying drawing 1 designs for the utility model;
Accompanying drawing 2 is the local enlarged diagram of accompanying drawing 1;
The plan structure schematic diagram of the internal combustion type domestic waste incineration that accompanying drawing 3 designs for the utility model;
Wherein, label 1 is a feed hopper, and 2 is adiabatic crown, and 3 is burner hearth, 5 is outlet flue, and 4 is body of heater, and 6 are the waste residue outlet, 7 is the waste heat boiler flue, and 8 is the waste heat boiler air-returen flue, and 9 is the gas bypass adjustment doors, 10 is tempering tube, 11 fire grates for band wind gathering sill, and 12 is air compartment, 13 is primary air intake pipe, and 14 is regulating gate, and 15 is waste heat boiler, 16 is the secondary air mouth, and 17 is the waste heat boiler smoke outlet flue, and 18 is the waste heat boiler water-intake pipe.
A kind of internal combustion type domestic waste incineration of the utility model design, comprise body of heater 4, the feed hopper 1 of body of heater one side upper end, the waste residue outlet 6 of opposite side, body of heater central authorities are burner hearths 3, the burner hearth below is provided with two row fire grates 11 of band wind gathering sill, one side of described fire grate is near feed hopper, and opposite side is near the waste residue outlet, is provided with tempering tube 10 at fire grate near end central authorities of feed hopper, be provided with 12 air compartments 12 on the fire grate lower surface, described air compartment is provided with the primary air intake pipe 13 of band regulating gate; The central authorities of corresponding burner hearth are provided with secondary air mouth 16 on the described body of heater, are provided with outlet flue 5 above the burner hearth near the waste residue outlet.

Described waste heat boiler is provided with flue 7, air-returen flue 8 and waste heat boiler smoke outlet flue 17, and water-intake pipe 18 in the pot.
The concrete course of work is:
Traveling-grate stoker makes from the rubbish of feed hopper and go through oven dry igniting, main combustion and after-flame process in burner hearth as the carrier of rubbish, becomes clinker and falls into the waste residue outlet; Flue gas is flowed through and is sent into air behind flue, air-returen flue and the smoke outlet flue of waste heat boiler and give hot device, and the bypass adjustment doors makes to be sent into the flue-gas temperature that air gives hot device and reach 450 ℃; To ignite the flame of rubbish of wind gathering sill on the fire grate is blown over to follow-up rubbish, lights follow-up rubbish; The rubbish that tempering tube makes its both sides is by built on stilts and more loose, and the wind that blows out makes the flame of front or high-temperature gas to its two side flow, lights the rubbish of its both sides, like this, rubbish is ignited from bottom and bottom, and oven dry and the rubbish above the burning fire grate realize being similar to process burnt in a heap.
After the rubbish that ignites entered the primary zone, fully air feed made its fierce burning and the generation high-temperature flue gas.At this moment, bed of material internal temperature can reach 900-1000 ℃, and clay matter lime-ash is dissolved.
At the suitable air feed of burnt zone, the fixed carbon in the burning out lime-ash cools off lime-ash simultaneously and makes it form clinker.
The flue gas of oven dry seed region contains toxic combustible gas, when flowing through the top, primary zone, meets high-temperature flue gas and the burned decomposition of secondary wind, flows through when burning the top, meets the further combustion decomposition of wind that is heated by slag.If oxygen concentration is low in the tail gas, carbonomonoxide concentration is higher, can increase secondary air flow, until up to standard.
About two rows totally two ten four air compartments, 24 primary air intake pipes are regulated and control respectively, realize carrying out air feed according to rubbish bed of material required airflow distribution curve above the fire grate.
The flue gas second-time burning is carried out in primary zone top to waste heat boiler flue this zone that enters the mouth, and temperature can reach
850-950 ℃, go through time＞2 second.
