The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described
In figure: depression bar 1, clamping device 2, taper bell 3, charging aperture 4, gas-liquid mixture collection channel 5, pipeline 6, holding pad 7, furnace shell 8, supporting member 9, thermostable heat-isolating coating layer 10, heat-insulation layer 11, fluorescence refractory lining layer 12, automatic ignition device 13, oxygen supply 14, venthole 15, distributor 16, air supervisor 17, stove pin 18, residue outlet 19, transversely strengthening hoop 20, converter body support bar 21.
As accompanying drawing 1, shown in accompanying drawing 2, garbage pyrolysis furnace of the present invention is by depression bar 1, clamping device 2, taper bell 3, charging aperture 4, gas-liquid mixture collection channel 5, pipeline 6, holding pad 7, furnace shell 8, automatic ignition device 13, oxygen supply 14, venthole 15, distributor 16, air supervisor 17, stove pin 18, residue outlet 19 compositions, taper bell 3 is arranged on body of heater top, taper bell 3 is provided with charging aperture 4, depression bar 1, clamping device 2, holding pad 7 forms strut device, strut device is arranged on taper bell 3 tops, clamping device 2 is arranged on depression bar 1, depression bar 1 is through taper bell 3, depression bar 1 bottom is connected with holding pad 7, upper of furnace body is provided with gas-liquid mixture collection channel 5 and pipeline 6, lower portion of furnace body is provided with residue outlet 19, oxygen supply 14 and automatic ignition device 13 are evenly distributed on bottom of furnace body, oxygen supply 14 is pipelines of upper end closed, on duct wall, have evenly downward-sloping venthole 15, automatic ignition device 13 is a heating wire, heating wire is spirally wrapped around on oxygen supply 14, the peak of heating wire is lower than descending most discharge pore on oxygen supply 14 duct walls, heating wire two ends are connected with power line, furnace shell 8 outer wall welding body of heater support bars 21 and transversely strengthening hoop 20, converter body support bar 21 and transversely strengthening hoop 20 are close to furnace shell 8 outer walls and are and intersect cross welding.The thermostable heat-isolating coating layer 10 scribbling on the inwall of furnace shell 8, heat-insulation layer 11 applies on thermostable heat-isolating coating layer, supporting member 9 is caused by reinforcing bar, for L-type designs, supporting member is close to furnace shell inwall and is welded on furnace shell on one side, supporting member 9 another side supporting fluorescence refractory lining layers 12.
The house refuse that recovery is marched into the arena enters in pyrolysis oven from the charging aperture 4 of taper bell 3 after fragmentation, drying and processing, fills after pyrolysis oven, at rubbish material top layer lid one asbestos layer, then seals charging aperture.The automatic ignition device 13 of bottom of furnace body starts, stove inner bottom part material generation pyrolytic reaction, and when automatic ignition device 13 temperature reach after 800 ℃ ~ 900 ℃, automatic ignition device 13 quits work.Material completes whole pyrolytic reaction by the heat of material generation that pyrolytic reaction occurs in stove.In pyrolytic process, in stove, send into air, air enters from air supervisor 17, evenly gives oxygen supply 14, then discharged by venthole 15 through distributor 16.After stove inner bottom part material pyrolysis a period of time, by rubbish material, become coke, coke space is large compared with rubbish material space, for reducing coke space, utilize the effect of clamping device 2, the power that provides depression bar 1 to move down, depression bar 1 drives holding pad 7, defeat top layer material in stove, material entirety is moved down, thereby the space of bottom coke is reduced, assemble the heat of coke, increase coke and the not contact area between pyrolysis rubbish, be conducive to the transmission of heat, promotes the carrying out of pyrolytic reaction.
Fluorescence refractory lining layer 12 is to be cast by high temperature resistant cement, white fused alumina, the rare earth oxide mixing piecemeal with fluorescent effect, is " product " font levels and is stacked up after moulding.Between material with every cast of layer, the gap between levels material adopts the mixture filling of high temperature resistant cement and asbestos putty.Every block of fluorescence refractory lining layer 12 material have two supporting members 9 supporting.Supporting member 9 is caused by reinforcing bar, for L-type designs, is 90 ° of angles.Supporting member 9 is close to the furnace wall of furnace shell 8 on one side, welds with furnace shell 8, and another side is used for supporting fluorescence refractory lining layer 12 material block, unaffected between every fluorescence refractory lining layer 12 material block.
Material generation pyrolytic reaction in stove in refuse pyrolysis process, the liberated heat when rare earth oxide in fluorescence refractory lining layer 12 with fluorescent effect has absorbed material pyrolysis, after rubbish material becomes coke, these rare earth oxides with fluorescent effect can send the light with some strength, effect of light is on coke, increase the heat of coke, heat up transmits, and provides more heat to the material of pyrolysis not, promotes material pyrolytic reaction evenly, stably carry out.
When bottom amount of coke reaches a timing, to spray in stove, add steam, steam enters from air supervisor 17, evenly gives oxygen supply 14, then discharged by venthole 15 through distributor 16.Steam enters in stove and contacts with coke, and series reaction occurs, and extracts the active ingredient in coke, makes to produce more high heating value combustion gas in pyrolytic reaction process, finally makes coke become linen inorganic matter ashes.Steam and air can be simultaneously, through air, be responsible for 17 entrances constantly sends in stove.
The gas-liquid mixture producing in stove in refuse pyrolysis process is pooled to gas-liquid mixture collection channel 5 through taper bell 3, then through pipeline 6, discharges out of the furnace.After in stove, rubbish material pyrolytic reaction finishes, the ashes in stove are discharged from the residue outlet 19 of lower portion of furnace body.
In pyrolytic process, in stove, temperature is higher, fluorescence refractory lining layer 12 expanded by heating, because heat-insulation layer 11 is to be filled and formed by the mixture of high temperature resistant cement and asbestos putty, there is certain shrinkage, make fluorescence refractory lining layer 12 there is certain expansion space, extend the service life of fluorescence refractory lining layer 12.The thermostable heat-isolating coating layer 10 that furnace shell 8 internal layers scribble can prevent that the heat in stove scatters and disappears toward stove effectively outward, makes to keep higher temperature in stove, improves the efficiency of pyrolysis.
In whole pyrolytic reaction process in stove rubbish material can be evenly, stably carry out, fuel gases calorific value that pyrolysis produces is high, output is large, has stronger economic benefit.
