In addition, a damper 1400 is installed at a predetermined position in communication with a pipe 1410 for supplying the gas heated and burned in the combustion chamber 1311 to the heating pipe 1140, and the gas heated in the combustion chamber 1311. In the cooling process that does not supply carbon to the carbonization chamber 1110, the damper 1400 is opened by the controller 1900 and controlled to supply external cooling air to the heating pipe.

Accordingly, when the waste heat is recovered and used, as shown in FIG. 10, the auxiliary burner 1330 and the burner 1320 in which the carbonized gas generated in the carbonization chamber 1110 is simultaneously supplied with fuel and air while the damper 1400 is closed. ) Is combusted in the combustion chamber 1311 and supplied to the heating pipe 1140, supplied to the carbonization chamber from the heating pipe, and the remaining residual heat is discharged to the outside through the outlet of the heating pipe.

It is essential to control the amount of fuel supplied to the nozzle burner 1320 in order to prevent the damage, and the temperature of the combustion chamber 1311 is sharply increased in the combustion chamber 1311 when the fuel is blocked in the process of supplying and blocking the fuel for fuel amount control. It is difficult to always maintain the ambient temperature above the temperature at which complete pyrolysis is possible. At this time, the auxiliary burner (1330) is necessary to maintain the atmosphere temperature in the combustion chamber at a temperature higher than that at which complete pyrolysis is possible, and to burn a trace amount of carbon gas that cannot be spontaneously ignited.

In the cooling process, as shown in FIG. 11, cooling air flows into the heating pipe 1140 rapidly while the damper 1400 is opened while only the air is supplied to the auxiliary burner 1330 and the burner 1320. Cooling is achieved.

In this cooling process, the cooling air is directly supplied to the inside of the heating pipe 1140 provided in the carbonization chamber to shorten the cooling time of the carbonization chamber, thereby shortening the treatment time and maximizing the treatment efficiency.

On the other hand, the waste carbonization apparatus of the present invention is connected to the connection passage of the exhaust gas discharged from the carbonization chamber 1110, by catalytic reaction of a very small amount of untreated raw materials during the pyrolysis process of the combustion device 1300 A catalyst box 1500 and a gas cooling device 1600 connected to the catalyst box 1500 to cool the temperature of the gas in accordance with an operation condition of a blower to describe a gas heated during a catalytic reaction.

Meanwhile, in the waste carbonization apparatus according to the embodiment of the present invention, as shown in FIGS. 1 and 12, a packing 1210 is installed to maintain airtightness between the carbonization chamber 1110 and the door 1200. In order to prevent the packing 1210 from being damaged by being exposed to high heat, a packing cooling device 1220 is installed to cool by forming a cooling flow path on an outer surface of the packing contact surface.

Here, the packing cooling device 1220 may include a water tank 1221 in which water is supplied through the water supply pipe 1227 and stored therein, and the water tank is connected to a pipe 1222 to supply water to the water tank.

That is, the carbonization treatment apparatus is essential to maintain airtightness by thermally decomposing the carbonization chamber 1110 in an oxygen-free (O ₂ ) state. The packing used to achieve this treatment condition must be flexible and durable to withstand high temperatures, but flexible materials (silicon and viton) lack durability at high temperatures and high-temperature materials (grawhite) lack flexibility and practically Not enough to meet the conditions. In order to meet these conditions, a cooling device is required around the packing to block the high heat transmitted so that the packing of the flexible material is exposed to high temperatures and is not damaged.

Hereinafter, an operation of a carbonization apparatus according to an embodiment of the present invention will be described with reference to FIG. 13.

The waste carbonization apparatus of the present invention is controlled by the control unit 1900 to proceed for each process, such as preparation → temperature raising and carbonization → cooling → termination → discharge.

In addition, each device is configured such that the output signal is operated only when the door 1200 provided in the front portion of the carbonization chamber 1110 is fully coupled in consideration of driving safety.

When the carbonization apparatus of the present invention is described in the preparation process, the pump 1223 of the packing cooling apparatus 1220 is operated when the power of the carbonization apparatus 1000 is turned on. Thereafter, when the start button is pressed on (ON) in the control unit 1900 of the carbonization processing apparatus 1000, the blower 1700 is operated, and the burner (nozzle burner; 1320) after a predetermined time has elapsed. The fuel pump 1321 and the ignition device mounted on the operation of the combustion proceeds inside the combustion chamber 1311. Then, the operation of the fuel pump 1321 and the ignition device mounted on the burner 1320 is repeatedly fired and ignited by the set temperature values in the carbonization chamber 1110 and the combustion chamber 1311.

In addition, when the temperature in the carbonization chamber 1110 or the combustion chamber 1311 is equal to or higher than a set value, the operation of the fuel pump 1321 mounted on the burner 1320 is stopped to stop the fuel supply, and the carbonization chamber 1110 and When the temperature in the combustion chamber 1311 falls below the set value, the fuel pump 1321 operates again to supply fuel. The supply and shut off of the fuel is repeated until the carbonization process is completed.

The temperature value is measured by the carbonization chamber thermocouple 1170 and the combustion chamber thermocouple 1340 installed in the carbonization chamber 1110 and the combustion chamber 1311.

Next, referring to the temperature raising process, after the burner 1320 is ignited, the fuel pump 1330a mounted to the auxiliary burner 1330 operates at a predetermined time interval, and the control unit 1900 of the carbonization apparatus 1000 operates. After pressing a start button in the ON (on) a predetermined time elapses, the stirrer 1120 operates, and when a predetermined time elapses after the stirrer operates, the operation of the stirrer is completely stopped. Thereafter, when the temperature in the carbonization chamber reaches the set value for the first time, the carbonization process is started, and the carbonization time setting timer of the controller (not shown) is operated, and when the time elapses, the carbonization process is terminated and the cooling process is switched.

The operation of the stirrer 1120 operates for a predetermined time every regular time.

In the cooling process, when the carbonization process is completed and the cooling process is completed, the operation of the fuel pumps 1321 and 1330a mounted to the burner 1320 and the auxiliary burner 1330 is completely stopped, and then the When the damper 1400 is opened and cooling air flows into the heating pipe 1140, the cooling process is completed when the temperature of the carbonization chamber 1110 drops to a predetermined temperature after the switching of the cooling process.

After the completion of the cooling process is completed, the process of the equipment is completed, the end indicator (not shown) controlled by the control unit 1900 is turned on, and when the process is completed, the pump 1223 of the packing cooling device 1220 Is stopped, and the operation of the blower 1700 is also stopped, while all the signals return to the initialization state.

After the cooling process is completed, pressing the discharge button (not shown in the control unit 1900) after the cooling process is completed, the stirrer 1120 mounted in the carbonization chamber 1110 is operated to discharge the carbide from the carbonization chamber 1110 ( 1131).

Here, the use and operation of the carbonization unit will be explained in more detail.

As shown in FIG. 13, first, the door 1200 is opened and waste (carbide) is introduced into the carbonization chamber 1110, the door 1200 is closed, and the door is completely coupled, and then the packing cooling device ( The pump 1223 of the 1220 is operated to depress “Power S / W,” not shown, of the control unit 1900 so that the coolant is supplied around the packing 1210 of the door 1200. After confirming the operation, press the “Start S / W” (not shown) of the control unit 1900 to operate the blower 1700, and after a predetermined time, fuel is supplied to the nozzle burner 1320 to allow the inside of the combustion chamber 1311. Combustion proceeds. At this time, the fuel supply and blocking of the burner 1320 is adjusted according to the set temperature value in the carbonization chamber 1110. Thereafter, the hot gas combusted in the combustion chamber 1311 is supplied to the heating pipe 1140 along the induction pipe 1410 (pipe), and the hot gas supplied to the heating pipe transfers heat into the carbonization chamber. After that, the temperature in the carbonization chamber 1110 is increased due to continuous heat transfer, and carbonization proceeds by supplying heat to the carbide. Next, carbonized gas (water vapor and VOC harmful gas) is generated in the process of carbonizing the carbonized material, and the generated carbonized gas flows into the combustion chamber 1311 of the combustion device 1300 along the pipe 1410 and burns the combustion device 1300. The high temperature thermal decomposition by the auxiliary burner (1330) provided on one side of the) is extinguished. The heat generated by the combustion of the carbonized gas is supplied to the heating pipe 1140 along the pipe 1410 and reused as a heat source for carbonizing the waste in the carbonization chamber 1110. Next, heat is supplied to the carbonization chamber 1110 through the heating pipe 1140, and the remaining heat of the combustion gas is introduced into the catalyst box 1500 along another pipe 1410. Next, a trace amount of harmful gas that is not processed in the high temperature pyrolysis process in the combustion chamber 1311 passes through a catalyst embedded in the catalyst tank 1500, and is destroyed. In addition, the combustion gas passing through the catalyst tank 1500 is discharged to the outside of the equipment through the exhaust fan 1700. When the high temperature combustion gas increased by the catalytic reaction passes through the exhaust fan 1700, the durability of the exhaust fan 1700 is increased. And since there is a possibility that the efficiency may be reduced by providing a gas cooling device 1600 in front of the blower 1700 to cool the combustion gas to a predetermined temperature or less to maintain the optimum conditions for the blower operation. On the other hand, a small amount of fine dust may be contained in the combustion gas discharged through the exhaust fan 1700, and is provided with a filtration filter 1800 capable of collecting fine dust at the rear end of the exhaust fan. In addition, the carbonized carbide through the above process is discharged to the outside of the carbonization chamber through the discharge port 1131 provided in the lower portion of the carbonization chamber 1110. At this time, the discharge of carbide is automatically discharged by driving the agitated carbide stirring agitator 1120 provided in the carbonization chamber 1110 without opening the door 1200.

Meanwhile, when the waste heat recovery system is described in more detail in the carbonization treatment apparatus of the present invention, when the operation of the equipment is started, a burner 1320 provided at one side of the combustion chamber 1311 is operated, and thermal energy of fuel burned in the combustion chamber. The carbon is supplied to the waste charged into the carbonization chamber 1110 through the heating pipe 1140 to perform carbonization. Carbonization gas generated during the carbonization process of the waste charged into the carbonization chamber 1110 is introduced into the auxiliary burner 1330 through the pipe 1410. The carbonized gas introduced into the auxiliary burner 1330 is mixed with and combusted with fuel and air for combustion in the combustion chamber 1311 and pyrolyzed at high temperature, and thermal energy generated in the combustion process is carbonized through the heating pipe 1140. Will be resupplied). The residual heat remaining after being supplied to the carbonization chamber 1110 is discharged to the catalyst box of the subsequent process through the heating pipe 1140 exhaust outlet. In other words, it is not a combustion process for extinguishing harmful substances contained in the carbonized gas by simply pyrolyzing the carbonized gas as described above, and recovering the thermal energy generated during combustion without disposing, and carbonizing the waste charged in the carbonized chamber. It is configured to be reused.

In the cooling process system, the heating pipe 1140 plays a role of supplying thermal energy and waste heat generated in the combustion chamber 1311 into the carbonization chamber 1110, and supplying external cooling air into the carbonization chamber during the cooling process. In parallel. When supplying heat energy and waste heat, the damper 1400 provided at the front of the heating pipe 1140 is closed so that no external cooling air flows to supply only the heat energy and waste heat generated in the combustion chamber 1311 to the carbonization chamber 1110. During the cooling process, the damper 1400 provided at the front of the heating pipe 1140 is opened so that the external cooling air is directly supplied to the carbonization chamber 1110 without passing through the combustion chamber 1311, thereby shortening the cooling time of the carbonization chamber and cooling efficiency. Can be maximized. On the other hand, it is possible to maintain the sensible heat of the combustion chamber, thereby saving energy for raising the combustion chamber during the next operation.
