Description

Refuse gasification heat storage burner and application method
Technical field
The present invention relates to a kind of rubbish heating field, particularly a kind of refuse gasification heat storage burner and application method.
Background technology
As the improvement of people's living standards, the yield of rubbish is also increasing, and burn for the routine of processing rubbish Mode.Conventional refuse burner is all single combustion chamber to traditional similar using the combustion furnace structure of conventional fuel, combustion Rubbish is directly poured into combustion furnace during burning to be burnt, and is directly discharged to waste gas greatly by simple purified treatment after burning In gas.Because single combustion chamber heat is inadequate, rubbish can not fully burn, and including in the mixture after burning can not largely fire The inorganic matter of burning, while also include the relatively low solid granulates of caused toxic gas and combustion rate after a large amount of burnings, and these Mixture carries very high heat energy, and waste gas so is directly discharged to not only cause in air to the waste of energy, will also result in ring The waste pollution in border and thermal pollution, and because the hot air temperature after burning is not high, supply boiler is in use, heating slowly, utilizes Rate is not high.
The content of the invention
It is an object of the present invention to provide a kind of refuse gasification heat storage burner and application method.The present invention not only may be used So that rubbish more fully burns, water wall body of heater can quickly be heated after burning, so as to which heat supply uses to boiler, and And the efficiency of heating surface is high, energy consumption is low, and environmental pollution and energy dissipation can be greatly decreased.
Technical scheme：Rubbish gasification heat storage burner, including water wall body of heater, water wall body of heater are provided with pot Stove, water wall body of heater is interior to pass through one layer of water pipe insulating course formation upper strata regenerator and lower floor combustion chamber, lower floor's regenerator bag Include combustion chamber and regenerator in parallel, be provided with fire grate below the combustion chamber, combustion chamber sidepiece is provided with rubbish feed mechanism, it is described simultaneously Joining regenerator includes interconnected regenerator A and regenerator B, regenerator A and combustion chamber, regenerator B and upper strata accumulation of heat Room connects.
In foregoing refuse gasification heat storage burner, the upper strata regenerator is one layer of U-shaped regenerator, U-shaped regenerator Import connected with regenerator B.
In foregoing refuse gasification heat storage burner, the upper strata regenerator is by the end to end U-shaped accumulation of heat of multilayer Room is formed, and the import of undermost U-shaped regenerator connects with regenerator B.
In foregoing refuse gasification heat storage burner, watertight sealing mechanism, watertight sealing mechanism bag are provided with below fire grate both ends Water tank is included, catch is provided with water tank.
In foregoing refuse gasification heat storage burner, in the upper strata regenerator provided with it is multiple shift to install up and down every Hot wall.
In foregoing refuse gasification heat storage burner, the fire grate sidepiece is provided with air blower.
In foregoing refuse gasification heat storage burner, the rubbish feed mechanism includes the long auger being obliquely installed, long Auger is connected with horizontally disposed short auger, and short auger is arranged on combustion chamber sidepiece, and the short auger side is provided with cloth air blast Machine.
According to the application method of foregoing refuse gasification heat storage burner, rubbish is burnt on fire grate, hot gas passes through Combustion zone carries out the heating removal of impurity into regenerator in parallel, and temperature rises to 1100-1300 DEG C, removes bioxin, while to water pipe Fireplace body and water pipe insulating course are heated, and are entered back into upper strata regenerator and are carried out heat storing and heat preserving, while to water wall body of heater and water Pipe insulating course is heated, and caused waste heat uses for other equipment.
In the application method of foregoing refuse gasification heat storage burner, method that the regenerator in parallel is heated up It is that hot gas enters regenerator A and carries out one or many accumulation of heat heatings, then enters regenerator B by through hole, is stored by extending The hot time improves hot air temperature, finally enters upper strata regenerator from the passage outlet at the top of regenerator B.
In the application method of foregoing refuse gasification heat storage burner, the upper strata regenerator carries out the side of heat storing and heat preserving Method is that hot gas is entered the import of U-shaped regenerator by regenerator B, by U-shaped regenerator it is multiple up and down shift to install every Hot wall carries out cut-off thermal-arrest, keeps stable hot air temperature.
Compared with prior art, the present invention is avoided by the way that rubbish is burnt on fire grate after burning by watertight sealing mechanism Being discharged to outside fire grate so that hot gas carries out the heating removal of impurity completely into regenerator in parallel, and temperature can rise to 1300 DEG C, due to The rise of temperature, most harmful substance can be removed, discharge gas is more clean, while water wall body of heater and water pipe are separated Layer is heated, and can be used after water wall body of heater and the heating of water pipe insulating course to boiler.The present invention can not only be such that rubbish more fills The burning divided, can quickly be heated after burning to water wall, and so as to which heat supply gives boiler to use, and the efficiency of heating surface is high, energy Consume low, environmental pollution and energy dissipation can be greatly decreased.The present invention is by increasing the heat exchanger time between hot gas and water pipe, energy Maximumlly utilize heat so that waste heat is generally 100-150 DEG C, and trans-utilization rate is high, and is carried out using watertight sealing mechanism Sealing, not only good sealing effect, hot gas can not escape, and simple in construction, easy to use.Supplied by using the present invention Heat, operating cost more than 50% can be reduced than the mode of routine, while the gas discharged is smokeless harmless odorless, can reach environmental protection Purpose.The present invention can significantly improve the temperature of burning gases by simple mode, reach as high as 1300 DEG C -1500 DEG C, so as to The efficiency of heating surface can substantially be accelerated.
The present invention is heated up more than 1200 DEG C by regenerator in parallel, can not only thoroughly be burnt, moreover it is possible to which bioxin is thoroughly removed Go.
