When the inside of the first vacuum control tank 241 is empty by forcibly transferring the cooling gas filled in the inside of the first vacuum control tank 241 to the combustion furnace 260 to prepare a suction process again Thus, the first vacuum control tank must form a vacuum again.

As shown in FIG. 10, the first vacuum control tank 241, the vacuum filter 251, and the vacuum pump 250 are connected through pipes, and among the valves provided in the apparatus of the present invention ( When V ₂ ) and the valve V ₃ are opened to open the associated pipe, the inside of the first vacuum control tank 241 again vacuums when the vacuum pump 250 is driven through the opened pipe. To form.

At this time, the air sucked from the first vacuum control tank 241 and sucked into the vacuum inlet 252 of the vacuum pump 250 is again discharged through the vacuum exhaust port 253 and the combustion furnace of the combustion furnace 260 After being introduced into the inlet pipe 263 and burned through the combustion furnace 260, it is discharged to the outside through the cooling tank 280 through the heating pipe 273 of the oil and water storage device 270. Air containing harmful substances (infectious bacteria, etc.), which are finely remaining in the first vacuum control tank 241 and are sucked into the vacuum pump 250, may be exposed to harmful substances (infection) by combustion in the combustion furnace 260. After the bacteria are removed).

The vacuum forming process of the first vacuum control tank 241 is the same process as that of the second vacuum control tank 242 which is sequentially driven with the first vacuum control tank 241.

Therefore, the intake, delivery, and vacuum forming process for the first vacuum control tank 241 described so far is the same as that of the first vacuum control tank 241 for the second vacuum control tank 242. In order to perform sequentially, when the first vacuum control tank 241 sucks the cooling gas, the second vacuum control tank 242 maintains a vacuum and waits for suction, the first vacuum control tank ( When the cooling gas is filled in 241, the first vacuum control tank 241 blocks the suction, and the second vacuum control tank 242 starts the suction of the cooling gas continuously and then the first vacuum control tank ( The full cooling gas of the 241 is discharged through the external air injection of the blower 290 and the first vacuum control tank 241 again forms a vacuum. This process is performed by the first vacuum control tank 241 and the second vacuum control tank 242 alternately to generate cooling from the incinerator 210 to be cooled and stored in the gas cooling storage device 220.

12 is a flow chart of a vacuum incineration method according to a preferred embodiment of the present invention.

The vacuum holding method of the waste incineration vacuum incinerator according to the preferred embodiment of the present invention by sequential driving of the first and second vacuum control tanks will be described with reference to FIGS. 2 to 12.

First, waste is put into the incinerator 210 for waste treatment (S301).

In step S301, the waste incinerator 214 into which the waste is injected is introduced into the heat generating unit 213 of the incinerator 210, and then the opening / closing door 211 is closed to open the heat generating unit 213 in the incinerator 210. It is a step of completely sealing.

Next, the combustion furnace 260 is heated (S302).

In the step S302, the vacuum pump 250 sucks air containing harmful substances (infectious bacteria, etc.) inside the incinerator 210 to form a vacuum with respect to the incinerator 210 into which the waste is injected and discharges it to the outside. In order to remove the harmful substances (infectious bacteria, etc.) from the air, the combustion furnace 260 may advance the combustion furnace 260 in advance to burn the air containing the harmful substances (infectious bacteria, etc.) at a high temperature. It is a step of heating.

Therefore, in the combustion furnace 260, the incinerator 210, the gas cooling storage device 220, and the first and second vacuum control tanks 241 and 242 are pumped by the vacuum pump 250 in a step to be described later. The air containing the harmful substances (infectious bacteria, etc.), which are heated before being sucked into the inside air and released to the outside, may be discharged after complete combustion in the heated combustion furnace 260. . The internal temperature of the heated combustion furnace is appropriately at least 300 ℃ or 400 ℃ to remove the harmful substances (infectious bacteria, etc.) by completely burning the air containing the harmful substances (infectious bacteria, etc.) It is desirable to keep it stable.

The combustion furnace 260 heated to such a temperature is preferably heated again to 850 ℃ or more in order to completely burn the gas generated by the thermal decomposition of the incinerator 210 later.

Next, an initial vacuum is formed in the incinerator 210, the gas cooling storage device 220, and the first and second vacuum control tanks 241 and 242 (S303).

The step S303 is an initial vacuum forming process, as shown in FIG. 6, wherein the incinerator 210, the gas cooling storage device 220, and the first and second vacuum control tanks 241 and 242 are provided. The valve (V ₁ ), valve (V ₂ ), valve (V ₃ ), connected to the vacuum pump 250 through the pipe through the vacuum filter 251 and the valves provided in the apparatus of the present invention are all closed. And after the valve V ₄ is opened and opened, when the vacuum pump 250 is driven, the incinerator 210, the gas cooling storage device 220, and the first and second vacuum control tanks 241 and 242. Is a vacuum.

When the initial vacuum is completed by such an action, the valve V ₁ , the valve V ₂ , the valve V ₃ , and the valve V ₄ are closed to maintain the vacuum state.

At this time, the vacuum completion state of the incinerator 210 can be confirmed by a conventional vacuum measuring instrument, which corresponds to a general configuration and its detailed description will be omitted.

Next, the incinerator 210 is heated (S304).

The step S304 is a step of performing a vacuum pyrolysis treatment on the waste introduced in the step S301, preferably adjusted to a temperature of 200 ° C. or more at which the waste is pyrolyzed.

Next, the first vacuum control tank sucks the cooling gas and the second vacuum control tank maintains the vacuum (S305).

In the step S305, after the initial vacuum is formed in the step S303, the valve V ₁ , the valve V ₂ , the valve V ₃ , and the valve V ₄ are closed to control the vacuum and the valve V ₅ . Open to connect the gas cooling storage device 220 and the first vacuum control tank 241. Therefore, the vacuum of the first vacuum control tank 241 in which the initial vacuum is made and the cooling gas stored in the gas cooling storage device 220 are exchanged with each other by the pressure difference from the gas cooling storage device 220. Cooling gas is automatically transferred to the first vacuum control tank (241).

Next, the first vacuum control tank is full and at the same time the second vacuum control tank sucks the cooling gas (S306).

In the step S306, the first and second vacuum control tanks are continuously formed so that the hot gas generated by the pyrolysis of the incinerator 210 is continuously sucked into the vacuum control tank through the gas cooling storage device 220. Is a sequential suction process, the valve (V ₅ ) is closed, the valve (V ₆ ) is opened and the first vacuum control tank 241 when the first vacuum control tank is full and can not achieve any more suction ) Is no longer sucked, and the second vacuum control tank 242 is continuously sucked.

Next, the cooling gas filled with the first vacuum control tank is sent out, and the second vacuum control tank continuously sucks the cooling gas (S307).

The step S307 is to transfer the filled cooling gas to the combustion furnace 260 to purify the cooling gas filled in the first vacuum control tank to the outside to achieve complete combustion, the first vacuum control In order to forcibly transfer the cooling gas from the tank 241 to the combustion furnace 260, the valve V ₇ and the valve V ₁₂ are opened, and the blower 290 is driven to operate the external air in the first vacuum control tank. 241 is injected into. At this time, the valve V ₆ is kept open so that the second vacuum regulating tank 242 achieves continuous cooling gas suction.

Therefore, the cooling gas filled in the first vacuum control tank 241 in accordance with the injection of the external air is forcibly pushed out through the first discharge pipe (241b).

In addition, when the high temperature gas (gas and moisture) generated by the pyrolysis of the incinerator 210 enters into the vacuum pump 250 by the pumping of the vacuum pump 250 in a later step, the vacuum pump may be damaged. Although the hot gas is cooled and sucked in the gas cooling storage device 220, the gas is not completely cooled, so that external air is injected into the first vacuum control tank 241 through the blower 290. The cooling and cleaning of the inside of the first vacuum control tank 241 is performed to completely prevent the failure of the vacuum pump 250, which may occur as the hot gas is introduced.

Next, the first vacuum control tank again forms a vacuum and the second vacuum control tank is continuously sucked (S308).

In step S308, when the cooling gas filled in the first vacuum control tank 241 is completely sent to the combustion furnace 260, the first vacuum control tank again forms a vacuum as a preparation step for the suction process. The valve V ₇ and the valve V ₁₂ are closed, and the valve V ₂ and the valve V ₃ are opened to connect the vacuum pump 250 and the first vacuum control tank 241. Let's do it. At this time, the valve V ₆ is kept open so that the second vacuum regulating tank 242 achieves continuous cooling gas suction.

When the vacuum pump 250 is driven while the vacuum pump 250 and the first vacuum control tank 241 are connected, a vacuum is formed in the first vacuum control tank 241 again so that the second vacuum to be described later. When the control tank 242 is full, it is possible to achieve the suction process sequentially again.

At this time, the water and impurities filtered by the vacuum filter 251 in the process of suctioning the air filled in the first vacuum control tank into the vacuum pump 250 when pumped to the vacuum pump 250 is the vacuum filter It is transferred to the oil and water storage device 270 through the second oil and water outlet 251a of 251 to be processed and discharged to the outside.

Next, while the second vacuum control tank is full, the first vacuum control tank continuously sucks the cooling gas (S309).

In the step S309, the second and first vacuum control tanks are continuously made so that hot gas generated by pyrolysis of the incinerator 210 is continuously sucked into the vacuum control tank through the gas cooling storage device 220. The sequential suction process is performed. When the second vacuum control tank is fully filled and no further suction is achieved, the valve V ₆ is closed and the valve V ₅ is opened to open the second vacuum control tank 241. ) Is no longer sucked, and the first vacuum control tank 242 continuously performs suction.

Next, the cooling gas filled in the second vacuum control tank is sent out, and the first vacuum control tank continuously sucks the cooling gas (S310).

The step S310 is to transfer the full cooling gas to the combustion furnace 260 to purify the cooling gas filled in the second vacuum control tank to the outside to achieve complete combustion, the second vacuum control In order to forcibly transfer the cooling gas from the tank 242 to the combustion furnace 260, the valve V ₈ and the valve V ₁₃ are opened, and the blower 290 is driven so that external air is supplied to the second vacuum regulating tank. 241 is injected into. At this time, the valve V ₅ is kept open so that the first vacuum control tank 242 achieves continuous cooling gas suction.

Therefore, as the external air is injected, the cooling gas filled in the second vacuum control tank 241 is forced out through the second discharge pipe 242b.

In addition, when the high temperature gas (gas and moisture) generated by the thermal decomposition of the incinerator 210 as described above in step S307 enters into the vacuum pump 250 by the pumping of the vacuum pump 250, the vacuum pump is damaged. Therefore, even if the hot gas is cooled and sucked in the gas cooling storage device 220, the gas is not completely cooled, and thus, external air may be supplied to the second vacuum control tank 242 through the blower 290. The injection is performed by cooling and cleaning the inside of the second vacuum control tank 242 to completely prevent the failure of the vacuum pump 250 which may occur as the hot gas is introduced.

Next, if the pyrolysis of the waste in the incinerator 210 is continuously made, the process is repeated in step S305, otherwise, if pyrolysis is completed, the process proceeds to the next step (S311).

When it is determined that the pyrolysis of the waste continues in step S311 and iterates to step S305, the processing in step S309, step S310, and subsequent step S305 is performed in steps S306 to S308. The process shows that the first vacuum control tank 241 and the second vacuum control tank 242 alternately operate and circulate sequentially.

However, when it is determined in step S311 that the pyrolysis of the incinerator 210 is completed, the filtered water discharged from the gas cooling storage device 220 and the vacuum filter 251 is discharged (S312).

In the step S312, the water and impurities filtered from the gas and the air passing through the gas cooling storage device 220 and the vacuum filter 251 are transferred to the inside of the water flow storage device 270 for purification, and then discharged to the outside. For the purpose, by opening the valve (V ₉ ) and the valve (V ₁₀ ) to filter the flow of water collected in the lower portion of the gas cooling storage device 220 and the vacuum filter 251 and the flow of the flow of water storage device (270) The heating pipe 273 is heated by the high temperature of the combustion gas discharged from the combustion furnace 260 through the inflow pipe 271 to the oil and water storage device 270. Evaporated and sterilized the flowing water introduced into the oil and water storage device 270 is sent to the cooling tank 280 in the cooling tank 280 is treated with the cooled gas and flowing water is discharged to the outside.

Next, the incinerator 210 is cooled (S313).

In the step S313, the user injects external air into the high temperature incinerator 210 after the first cycle of the waste incineration vacuum incinerator of the present invention using the blower 290, and cools the incinerator 210 to low temperature. The valve (V ₁ ), valve (V ₁₂ ), and valve (V ₁₃ ) to protect the user handling the incinerator (210) from the high temperature incinerator (210) for loading new waste. ) To open the external air injection by the blower 290 to the incinerator 210 to cool the incinerator 210.

In addition to such a series of processes, after the gas generated by the pyrolysis of waste in the incinerator 210 is cooled and stored in the gas cooling storage device 220, the first and second vacuum control tanks 241, In case of an emergency situation in which the pressure of the gas cooling storage device 220 and the vacuum control tanks 241 and 242 connected to the gas cooling storage device 220 exceeds a reference value, the pressure automatic adjustment is performed. The device 230 is operated so that the connection between the gas cooling storage device 220 and the combustion furnace 260 is ON, so that the pressure is automatically adjusted to prevent an accident from occurring.

When the first cycle proceeds through all of these processes, the complete vacuum pyrolysis treatment for the once loaded waste is completed.
