It is often necessary to add a combustion improver to help the garbage burn, and the investment is large and the operating cost is high. High, and later there was a pyrolysis and gasification incineration method. The waste gas was pyrolyzed and gasified by a combustion chamber of a rotary kiln, a fluidized bed or a gas-controlled incinerator, and then the combustible gas was burned in the second combustion chamber. Pyrolysis and gasification incineration can produce high calorific value combustible gas. The combustion temperature in the second combustion chamber is high, and the garbage can be fully burned out.

See Figure 1A and Figure 1B. The high-temperature dry distillation waste incinerator of the present invention comprises two front and rear incineration tunnels of identical construction except that their inlets and outlets are opposite, and a refractory layer 6 is provided at the top of the incineration tunnel. Each incineration tunnel is divided into three zones. • Drying zone 3. Dry distillation burning zone 7 and burning zone 11. The drying zone 3 is further divided into a pre-drying zone and a post-drying zone. The entrance is a pre-drying zone, the top of the furnace is straight, the garbage incineration vehicle is filled with garbage and the smoke is blocked, and the top of the furnace is away from the garbage incineration vehicle. 0.5 m at the top, equipped with dry distillation garbage. According to different requirements, the distance is feasible within the range of 0.2-0.8 m. After the two garbage incineration vehicles are the drying area, the top wall of the tunnel in the post-drying area is arched. The shape of the dome is increased by 0.5 m relative to the top wall of the tunnel in the pre-drying zone, and the distance is in the range of 0.2-0.8 m. The zone is provided with an exhaust pipe 4, a dry distillation zone 7 and an upper arch of the tunnel. The top is increased by 0.2-0.8 m relative to the tunnel arch in the post-drying zone to form a combustion furnace for the full combustion of the combustible gas. The height of the top of the burning zone 11 is the same as that of the pre-drying zone.

The garbage incineration vehicle 18 enters from the inlet 1 and is slowly pushed into the incineration tunnel by the hydraulic cylinder 20. The garbage inlet 2 is provided above the tunnel, and the garbage is filled with the garbage incineration vehicle 18 from the top inlet. The drying zone 3 of the former incineration tunnel is just adjacent to the burning zone 11 of the post-incineration tunnel, and the drying zone 3 of the post-incineration tunnel is just adjacent to the burning zone 11 of the former incineration tunnel, and the auxiliary induced draft fan is used to burn the tunnel burning zone 11 The hot air is heated through the waste heat outlet 14 of the burning zone and the waste heat inlet 40 of the drying zone of the former incineration tunnel to heat the garbage that has just entered the incineration tunnel, so that even if the garbage having a large moisture content is dried, it can be stably incinerated. At the same time, under the suction of the auxiliary induced draft fan, the garbage incineration vehicle 18 near the dry distillation combustion zone 7 starts to burn, further drying and heating the waste in the upper part of the garbage incineration vehicle 18, and the waste gas and garbage discharged from the front incineration tunnel auxiliary draft fan. The water vapor in the exhaust gas is sent to the dry distillation combustion zone 7 of the post-incineration tunnel through the exhaust gas exhaust pipe 10 for secondary combustion, and the post-incineration tunnel assists the exhaust gas discharged from the induced draft fan and the water vapor in the garbage to be sent to the front incineration through the exhaust gas exhaust pipe 10. The retorting combustion zone 7 of the tunnel is subjected to secondary combustion to completely burn off strong carcinogens such as dioxins, and to solve the current drying and gasification at low temperatures. A world problem that produces excessive levels of dioxin emissions. In the dry distillation combustion zone, the air extracted by the exhaust fan causes the garbage in the incinerator to burn rapidly, and the high temperature generated by the flammable gas generated by the retorting in the furnace, causing the garbage in the upper part of the garbage incinerator 18 and the garbage inside the incinerator to be sharp. Drying, rapid decomposition, a large amount of flammable gas is released from the inside of the garbage, and the combustible gas is continuously supplied to the furnace to burn violently until the garbage is completely burned out. In the burning zone 11, the garbage on the garbage incineration vehicle 18 has been retorted or burned, leaving the residue of carbides to continue to burn, so that the air here maintains a relatively high temperature, through the waste heat outlet 14 of the burning zone, the drying zone The waste heat inlet 40 is sucked by the auxiliary induced draft fan of the post-incineration tunnel to dry and heat, and then incinerate the garbage newly entered into the tunnel. The temperature of the incombustible material remaining on the incinerator is gradually lowered, and finally the outlet 12 is pushed out of the furnace for unloading. .

The garbage incinerator is placed close to the side wall of the incineration tunnel, and the top of the garbage incineration is densely packed with 0.5 m thick garbage, causing anoxic state for dry distillation. There are three upper, middle and lower grate, the upper grate is welded with four grate 22, the middle grate is welded with 9 intermediate grate 23, and the lower grate is welded with 18 lower grate 24, which are three-layer grate The garbage is racked up, so that the volume of the dry distillation waste in the upper part of the incineration vehicle is reduced and the volume is reduced, and the upper layer of the grate is burned and burned; the upper grate is burned and dried, and the volume is reduced, and the inner grate is continuously burned; the middle layer garbage After combustion and retorting, the volume is reduced and falls to the lower grate to continue burning. The garbage is dropped to expose the internal garbage, and it can continue to burn and dry distillation. Even if the original garbage is densely loaded, it can be burnt through, and the function of "automatic ignition" can be completely burned out. The base 27 of the incinerator is welded by channel steel, and the upper bottom plate 25 is provided thereon, and four wheels 26 are mounted on the lower side to slide on the traveling rails 21. A groove of channel steel is welded on top of the base 27, the bottom layer of the furnace bar 24 is supported, four columns 28 are welded on the channel steels on both sides, and the intermediate grate 23 is supported by two channels of steel, and 8 pieces are used thereon. The column supports the top layer of the furnace strip 22, and the inner wall 29 of the steel plate is welded on the upper and lower sides of the channel steel. The two sides of the incinerator are corresponding to the interval between each two bars, which are venting holes 30, and the air can enter from the venting holes 30 on both sides. , the internal garbage of the incineration vehicle is fully burned, and the purpose of completely burning the garbage is achieved. Depending on the size of the incinerator, the entire incineration tunnel can be loaded with many incinerators. As a practical example, each incineration tunnel is 60 meters long and can accommodate 30 incinerators at the same time. After the incinerator is ignited, it can work continuously for a long time without adding a combustion-supporting agent. The incinerator should be replaced with a burning vehicle without stopping the operation of the incinerator.

See Figure 3. In the present invention, the exhaust gas induced draft fan 32 draws the exhaust gas of the combustion waste from the collecting flue gas pipe 9 of the dry distillation combustion zone 7 through the connecting pipe 31, and sends it to the exhaust gas washing tank 35. Since the cross-sectional area of the exhaust gas scrubbing tank 35 is much larger than the cross-sectional area of the exhaust gas intake pipe, the velocity of the exhaust gas entering the exhaust gas scrubbing tank is greatly reduced, and the suspended soot is dropped into the exhaust gas scrubbing tank. The washing tank is filled with lime water with alum and freshener, and a plurality of water spray pipes 23 are arranged above, and the water spray pipe 23 has enough water spray ports, and the water pump extracts the washing liquid from the washing pool through the spray pipe from top to bottom. The multi-layer water curtain is formed, and the exhaust gas is washed by a plurality of water curtains to remove the smoke and odor from the exhaust gas and neutralize harmful substances such as HC1, NOx, SOx and COx in the exhaust gas, and the exhaust gas meets or exceeds the exhaust emission standard, and passes through the chimney row. Go into the sky.

In the present invention, the two rails 21 in the front and rear incineration tunnels can be connected by circular arc tracks at the ends of the two incineration tunnels to form a closed rail, and can also be connected by a lateral moving mechanism.

When the garbage incinerator 18 is removed from the outlet 12 of one of the incineration tunnels by the driving means of the incineration tunnel, it is moved to the traverse rail 42. The traverse bracket has 4 wheels that can slide on the traverse track. The ends of the chain are fixed and are simply wound by two guide sprockets 47 onto the drive sprocket 49 of the drive motor 48. When the motor is started, the drive sprocket 49 rotates, and the traverse bracket 41 is driven to slide along the traverse track 42 to another The entrance to the incineration tunnel is stopped. At this time, the track under the incinerator 18 has been engaged with the carriage track 21 in the other incineration tunnel, as shown by the dashed line in FIG. The hydraulic cylinder 20 pushes the garbage incinerator 18 that has been sent to the incineration tunnel, and starts to enter another incineration tunnel to load the garbage. After the garbage is filled, the traverse bracket 41 returns to the original incinerator outlet under the reversal action of the driving motor 48. position. The entire course of action can be automatically controlled by the computer.

Referring to Fig. 5, the dust discharging device of the present invention is a rotatable hydraulic cylinder 50 and an incinerator stopper 51.

The piston rod of the hydraulic cylinder is supported by the shaft of the rear wheel of the garbage incinerator, and the front wheel is stopped by the stopper 51 of the bracket, and the whole garbage incinerator is tilted to 50. - At 70 °, the non-combustible ash in the incineration vehicle is discharged to the ash discharge tank 46, then the hydraulic cylinder is dropped, and the garbage incineration vehicle is returned to the horizontal position for traverse. The ash poured into the ash discharge tank 46 is sieved and sent to the ash storage.

The incineration process of the present invention only requires that the incinerator be loaded with wood on the three layers of the first and second incinerators at the beginning of operation, and the third and fourth incinerators are loaded with two layers of wood, and the upper layer is filled with garbage. After that, each incinerator only put wood on the bottom layer of the furnace, and all of it was filled with garbage. The incinerator was filled from the entrance to the extinguishing area of the incinerator, and a little diesel was poured into the first incinerator to ignite the wood for combustion. The incineration tunnel is baked, and the incinerators filled with garbage are continuously entered. No need to add any combustion improver, the incineration process can be carried out continuously for a long time, which greatly reduces the cost of garbage disposal, and is convenient, labor-saving and energy-saving.
