Vacuum Incineration Apparatus For Waste Disposal and Vacuum Preservation Method Thereof

1 . A vacuum incineration apparatus for waste disposal, comprising:

an incinerator for thermally decomposing waste;

a combustor for burning gas generated from the waste thermally decomposed in the incinerator; and

a vacuum forming unit for making the incinerator vacuous,

wherein the vacuum forming unit keeps the incinerator vacuous by forcedly and continuously sucking in the generated gas.

2 . The vacuum incineration apparatus for waste disposal according to claim 1 , wherein the vacuum forming unit comprises a plurality of vacuum regulating tanks for sucking in the gas discharged from the incinerator, and a vacuum pump for making the plurality of vacuum regulating tanks vacuous, and

wherein the plurality of vacuum regulating tanks operate sequentially according to a predetermined order and forcedly suck in the generated gas by exchanging the generated gas with the vacuum of the vacuum regulating tanks.

3 . The vacuum incineration apparatus for waste disposal according to claim 2 , wherein the plurality of vacuum regulating tanks comprises a first vacuum regulating tank and a second vacuum regulating tank, wherein the first vacuum regulating tank is disconnected from the incinerator when the first vacuum regulating tank reaches a predetermined pressure as the first vacuum regulating tank sucks in the gas discharged from the incinerator, and at the same time, the second vacuum regulating tank is connected to the incinerator so that the second vacuum regulating tank continuously sucks in the gas generated from the waste thermally decomposed in the incinerator.

4 . The vacuum incineration apparatus for waste disposal according to claim 3 , further comprising a ventilator for introducing external air into the plurality of vacuum regulating tanks,

wherein, when one of the plurality of vacuum regulating tanks reaches a predetermined pressure as the one vacuum regulating tank sucks in the gas discharged from the incinerator, the introduction of the gas into the incinerator is interrupted, and then the ventilator is actuated to discharge the sucked gas to the combustor.

5 . The vacuum incineration apparatus for waste disposal according to claim 3 , further comprising a vacuum filter provided at a front stage of the vacuum pump.

6 . The vacuum incineration apparatus for waste disposal according to claim 1 , further comprising a gas cooling and storing unit having one end connected to the incinerator and the other end connected to the vacuum forming unit for cooling and storing the gas discharged from the incinerator before the gas is fed into the vacuum forming unit.

7 . The vacuum incineration apparatus for waste disposal according to claim 6 , further comprising an automatic pressure regulating unit for directly discharging the gas from the gas cooling and storing unit to the combustor when a pressure of the gas cooling and storing unit exceeds a predetermined value.

8 . The vacuum incineration apparatus for waste disposal according to claim 6 , further comprising a flowing water storing unit provided at a rear stage of the combustor, the flowing water storing unit including a heating pipe through which high-temperature burned gas discharged from the combustor passes,

wherein the flowing water storing unit sterilizes and vaporizes flowing water discharged from the gas cooling and storing unit and the vacuum filter.

9 . A vacuum preservation method of a vacuum incineration apparatus for waste disposal, the method comprising:

a first step of initially making an incinerator into which waste is injected and a plurality of vacuum regulating tanks vacuous;

a second step of heating the incinerator; and

a third step of keeping the incinerator vacuous as the plurality of vacuum regulating tanks forcedly and continuously suck in gas generated from waste thermally decomposed in the incinerator.

10 . The vacuum preservation method according to claim 9 , wherein, in the third step of keeping the incinerator vacuous, the plurality of vacuum regulating tanks operate sequentially according to a predetermined order and forcedly suck in the gas generated from the waste thermally decomposed in the incinerator by exchanging the generated gas with the vacuum of the vacuum regulating tanks.

11 . The vacuum preservation method according to claim 10 , wherein the plurality of vacuum regulating tanks comprises a first vacuum regulating tank and a second vacuum regulating tank, and

wherein the third step of keeping the incinerator vacuous comprises:

a fourth step in which the first vacuum regulating tank sucks in the gas discharged from the incinerator;

a fifth step in which the first vacuum regulating tank is disconnected from the incinerator when the first vacuum regulating tank reaches a predetermined pressure, and the second vacuum regulating tank is connected to the incinerator so that the second vacuum regulating tank continuously sucks in the gas discharged from the incinerator;

a sixth step in which the gas is discharged from the first vacuum regulating tank disconnected from the incinerator, and then a vacuum pump make the first vacuum regulating tank vacuous again;

a seventh step in which the second vacuum regulating tank is disconnected from the incinerator when the second vacuum regulating tank reaches a predetermined pressure, and the first vacuum regulating tank is connected to the incinerator so that the first vacuum regulating tank continuously sucks in the gas discharged from the incinerator; and

an eighth step in which the gas is discharged from the second vacuum regulating tank disconnected from the incinerator, and then the vacuum pump make the second vacuum regulating tank vacuous again.

12 . The vacuum preservation method according to claim 11 , further comprising a ninth step in which the fifth to eighth steps are repeated until incineration of the waste in the incinerator is completed.
