The screw 131 penetrates from one end to the other end, and an air supply nozzle 150 for supplying the purified air supplied by the purified air conveying unit 400 to one end is connected to idling. Since the air supply nozzle 150 is connected to the screw through a bearing (not shown), even when the screw 131 is rotated, the air supply nozzle 150 can supply air in a non-rotated state. In addition, the other end of the screw 131 is connected to a connecting pipe 160 positioned at the waste discharge unit 140 while air flows therethrough. And, the connection pipe 160 is connected to the complete combustion unit (200).

The power transmission unit 133 includes a driven pulley formed on the outside from one end of the screw 131 , a driving pulley formed on the motor shaft of the motor 132 , and a driven pulley and a belt wound around the driving pulley.

The waste discharge pipe body 143 is built in the discharge pipe body 142 and is composed of a pipe whose inner space is opened at both ends, and the inner diameter D1 of one end is formed to be the same as the inner diameter of the main combustion tank 110, and the other end of The inner diameter (D2) is formed larger than the inner diameter of the main combustion vessel (110). Therefore, as the waste discharge pipe body 143 rotates together with the discharge pipe body 142, the burning waste can be discharged while moving from one end to the other.

Such, the waste discharge pipe body 143 may be manufactured as a castable (Lightweight Castable). Castable is a mixture of alumina cement with porous aggregate and has a maximum safe operating temperature of 1,800~2,000 degrees Celsius.

In addition, the waste discharged in a state of being combusted in the waste discharge pipe body 143 may be provided to the complete combustion unit 200 .

In this way, when the ignited waste is input through the input hopper 120 , the continuously input wastes are transferred by the waste transport unit 130 in a burning state. In addition, the transferred wastes may be provided to the complete combustion unit 200 as they are gradually moved in the rotating waste discharge pipe body 143 while continuous combustion is made.

As shown in FIGS. 4 to 6 , the complete combustion unit 200 has an inlet 211 through which waste supplied in a state of being combusted by the combustion unit 100 is introduced at one end, and is generated as the waste is burned. The internal combustion tank 210 having a through-hole 212 through which the waste gas and ash are penetrated is formed at the other end, and the internal combustion tank 210 is rotatably built into the internal space, and the through-hole 212 of the internal combustion tank 210 is formed. ), an external support cylinder 220 in which a waste gas outlet 221 through which the waste gas is discharged and a redistribution port 222 through which the ash is discharged, and a tank rotating member 230 for rotating the internal combustion tank 210; It includes a tank rotation guide 240 for guiding the rotation of the internal combustion tank 210 , and an air injection unit 250 for spraying air into the internal combustion tank 210 .

The internal combustion tank 210 is formed with a lightweight castable on the inner circumferential surface, and the inner diameter of the other end is larger than the inner diameter of one end through which the waste is introduced. That is, the internal combustion tank 210 may be configured the same as the waste discharge pipe 143 . Therefore, when the internal combustion tank 210 is rotated, the burned waste is gradually moved from one end to the other, so that the complete combustion of the waste can be easily achieved.

A plurality of inlets 211 are formed to be radially dispersed, and as the internal combustion tank 210 is rotated, the waste discharged through the waste discharge pipe 143 of the combustion unit 100 is discharged to the inlets 211 at once. It may not flow in and may flow in sequentially.

The external support cylinder 220 is fixed to the ground by a bracket. The waste gas outlet 221 is formed in the center at the other end of the external support barrel 220 , and the redistribution hole 222 is formed in the lower part at the other end of the external support barrel 220 . A re-discharge unit 223 using a screw or a conveyor belt is connected to the re-discharge port 222 to transfer the ash. Accordingly, the ash is discharged to a separate facility by the re-discharging unit 223 and processed.

And, the outer support cylinder 220 has an outer hole 224 that penetrates to the outside, and a hole that penetrates downwardly is formed so that the tank rotation guide 240 passes therethrough.

The tank rotation guide 240 includes a plurality of support rollers 241 for supporting both sides and front and rear in the lower portion of the internal combustion tank 210, and a support bracket 242 to which the support rollers 241 are rotatably fixed, respectively. do.

Since the support roller 241 is composed of four and supports the lower portion of the internal combustion tank 210 in a dispersed state, the internal combustion tank 210 can be rotated in a stable state.

The support bracket 242 is composed of four and is supported on the ground while being respectively connected to the support rollers 241 through holes formed in four places in the lower portion of the external support tube 220 .

Accordingly, when air is supplied from the connection pipe 160 to the main pipe body 252 , the air is radially sprayed by the dispersion nozzles 253 . That is, since air is injected from the center of the internal combustion tank 210 to the outside, the waste can be easily combusted.

The inner air injection unit 255 is formed in an air supply unit 256 through which air flows therein while being formed in a ring shape at one end of the external support cylinder 220, and is formed in the air supply unit 256 to provide a purified air transmission unit 400. It includes an air injection unit 257 into which the purified air supplied by the inlet is injected, and a plurality of air injection nozzles 258 that are formed to be dispersed in the air supply unit 256 and inject air.

Since the air supply unit 256 is formed in a ring shape, air can be evenly distributed in the inner space. Thereby, air may be uniformly sprayed from the air injection nozzles 258 that are formed to be radially dispersed.

Accordingly, the air injected from the air injection nozzles 258 can be directly provided to the burned waste, so that the complete combustion of the waste can be maximized.

The waste gas inlet pipe 320 is connected to the waste gas outlet 221 of the external support tank 220 .

Here, the waste gas inlet pipe 320 may be connected to the heating device and the outer case 310 so that the high-temperature waste gas is supplied to the outer case 310 after it is used for heating. In addition, the waste gas inlet pipe 320 may be designed so that the high temperature waste gas is provided to the outer case 310 after being used for power generation.

As the diameter of the inner case 330 is formed smaller than the diameter of the outer case 310 , the inner case 330 is positioned at the center of the outer case 310 .

The lower purifying unit 340 includes a reservoir 341 in which purified water is stored, an on/off valve 342 for opening and closing a drain hole formed through the lower portion of the reservoir 341, and an upper portion of the reservoir 341 . and a water level sensor 343 for measuring the water level and a control unit 344 for controlling the on/off valve 342 based on the measurement of the water level sensor 343 .
