1 is a view showing an integrated combustion system configuration including the rapid high temperature sterilization drying apparatus of the present invention.

Referring to FIG. 1, a system capable of drying fuel, burning fuel, and purifying combustion gas is configured, and a drying apparatus 20 which processes drying and sterilization of a fuel containing water by using heated heating medium oil. And a combustion device 10 which burns the fuel dried by the drying device 20 using the falling combustion gas while rotating along the inner wall of the combustion chamber and provides the combustion gas used for combustion to the drying device 20. And a purifier 30 for removing and purifying foreign substances contained in the combustion gas used for heating the heat medium oil in the drying apparatus 20.

In detail, as the outside air is introduced into the combustion chamber to burn fuel, which is a combustion target inside the combustion chamber, combustion gas used for combustion is discharged through the combustion gas discharge duct 11.

Then, the hot combustion gas (hereinafter referred to as "hot combustion gas") exiting through the combustion gas discharge duct 11 is supplied into the drying apparatus 20 through the combustion gas moving duct 12. At this time, in the drying apparatus 20, the heat medium oil is accommodated for drying and sterilizing the fuel, and the combustion gas provided through the combustion gas moving duct 12 is used to heat the heat medium oil to a high temperature.

On the other hand, after the combustion gas is used to heat the heat medium oil in the drying device 20 and dry the fuel, the combustion gas is purified through the purification device connecting duct 13 connected to the drying device 20. Are transferred to 30. In the purification device 30, a cleaning process is performed to remove foreign substances contained in the combustion gas used for combustion in the combustion device and used for heating the solution in the drying device and then discharge them to the outside.

Before explaining the drying apparatus 20 which is this invention, the said combustion apparatus 10 is demonstrated briefly.

2 is a view showing the configuration of a combustion device constituting an integrated combustion system.

The drying apparatus of the present invention serves to dry a fuel containing moisture by using a liquid heated to a high temperature such as cooking oil, wherein the heating gas used in the combustion apparatus 10 utilizes the combustion gas.

The combustion of the fuel using the combustion gas and its discharge will be briefly described with reference to FIG. 2, except that the combustion device illustrated in FIG. 2 is just one example of supplying combustion gas used as a drying device. However, it is not necessarily limited to the structure of FIG.

Referring to FIG. 2, the combustion apparatus is formed in the flame flame column inner cylinder 91 in which the combustion gas is rotated by centrifugal force and complete combustion is performed using this combustion gas. Then, ashes generated by the combustion are moved to the lower side of the inner cylinder 20, and the rotary gear chamber 40 is rotated under the inner cylinder 91 to help the ash collection.

In detail, the combustion apparatus includes an inner cylinder 91 and an outer cylinder 90 arranged to be spaced apart at predetermined intervals, and the outer cylinder 90 has a shape surrounding the inner cylinder 91. Both the outer cylinder 91 and the inner cylinder 90 are configured to allow multiple combustion gases to flow in, so that the width thereof gradually increases from the top to the bottom.

In the combustion apparatus of one embodiment, the combustion gas gradually descends while rotating along the inner wall of the inner cylinder 91, and a combustion object continuously supplied below the inner cylinder 91 is burned by the hot heated air during the lowering.

Then, the ash generated according to the combustion is moved to the ash collecting cylinder 70, the lower portion of the inner cylinder is not rotated, but instead of rotating the respective components of the rotary gear chamber 40 so that the processing and movement of the collected ash is made.

In addition, in the illustrated combustion apparatus, combustion gas is supplied through the first to fourth combustion gas supply pipes, and a lower portion of the inner cylinder 91 is used even if a lower pressure is used as compared to the case of supplying a large amount of combustion gas to one supply pipe. The combustion gas can travel until.

Since the combustion gas introduced through the first to third combustion gas supply pipes 1, 2 and 3 rises along the main flow path until it descends by the blocking film 15, the first to third combustion gas supply pipes ( 1,2,3) can be referred to as an upward feed pipe.

On the other hand, since the combustion gas which flowed in through the 4th combustion gas supply pipe 4 descend | falls, rotating the main flow path (space between an inner cylinder and an outer cylinder), it can be called a descending supply tube.

Since the size of the outer cylinder 90 to which the second combustion gas supply pipe 2 is connected is larger than the size of the outer cylinder 90 to which the first combustion gas supply pipe 1 is connected, the first combustion gas supply pipe 1 is formed. It is comprised so that the 1st combustion gas which flows in and falls along the inner wall surface of the inner cylinder 91 may fall smoothly.

The size of the inner and outer cylinders at the position where the first combustion gas supply pipe 1 configured at the highest position is connected is smaller than the size of the inner and outer cylinders at the connected position which is the second combustion gas supply pipe 2 configured at the lower position. . Because, as shown, there should be no obstruction in the falling of the air introduced into the combustion chamber through the first combustion gas supply pipe (1), and below it into the combustion chamber through the second combustion gas supply pipe (2) In order to be able to smoothly merge with the incoming air, it must be in such a stepped shape.

The combustion gas supplied through the first to third combustion gas supply pipes 1, 2, and 3 rises while rotating along the space formed between the outer cylinder 90 and the inner cylinder 91 (i.e., the 'main passage'). The direction of movement is changed and lowered by the blocking film 15 between the inner cylinder 91 and the outer cylinder 90. That is, the flow path is changed so that the combustion gas rising while rotating along the main flow path descends while rotating along the inner wall of the inner cylinder 91 by the blocking film 15.

On the other hand, the induction nozzle 80 for smoothly moving up or down while the combustion gas flowing through the first to fourth combustion gas supply pipes (1, 2, 3, 4) is rotated and the outer cylinder 90 It can be configured between the inner cylinder (91).

In the present embodiment, the combustion gas supplied to the main flow passage 21 between the outer cylinder 90 and the inner cylinder 91 may use external air as it is without needing to be heated or cooled separately, and the combustion gas rotates and is a fuel to be burned. It rises sharply while descending to (F). It is necessary to block the high temperature of the inner cylinder 91 which forms a combustion chamber from being transmitted to the outer cylinder 90, and it is necessary to cool the outer cylinder 90 which forms the exterior.

Since the combustion gas uses the outside air, the combustion gas flowing through the supply pipe has a relatively low temperature compared with the heated air inside the combustion chamber, so that the external cylinder 90 is naturally cooled.

In addition, in this embodiment, the heat insulating material 92, 93, 94 is comprised between the outer cylinder 90 and the inner cylinder 91 in order to suppress that the high temperature of the inner cylinder 91 is transmitted to the outer cylinder 90. FIG.

The rotary gear chamber cooling air supply pipe 5 and the refrigerating chamber cooling air supply pipe 6 also serve to adjust the pressure between the combustion chamber inside (inner cylinder) and the pressure of the rotary gear chamber 40. The ash contained in the rotating combustion gas is caused to move toward the rotary gear chamber 40 by its own weight. That is, the ash which rotates together with the combustion gas in the combustion chamber is rotated by the pressure of the air supplied to the rotary gear chamber cooling air supply pipe 5 and the chamber cooling air supply pipe 6 not higher than the pressure inside the combustion chamber. Adjust the pressure to move to the (40) side.

That is, the air supplied through the rotary gear chamber cooling air supply pipe 5 and the re-chamber cooling air supply tube 6 serves to adjust the pressure inside the rotary gear chamber 40, and the rotary gear chamber ( 40) If air is supplied such that the internal pressure is equal to the internal pressure of the combustion chamber, the ash contained in the combustion gas rotating inside the combustion chamber can be naturally moved toward the rotary gear chamber 40 by its own weight.

The rotary gear chamber cooling air supply pipe 5 is configured to descend the air flowing therein, and is disposed above the gear part 41. In order not to transmit the high temperature inside the combustion chamber to the gear part 41 side, the heat insulation wall 14 is arrange | positioned between the gear part 41 and a combustion chamber.

And it rotates about the fuel (F). The rotating plate 47 rotates around the fuel, that is, the outer cylinder 90, inside the rotary combustion chamber 40, and the connecting member 48 and the cleaning blade 44 connected thereto with the rotation of the rotating plate 47. And the sweeper 45 is also rotated.

The grate 90 has a plurality of grate holes 91 are spaced apart from each other, the ash is moved to the bottom surface of the sweeper 45 and the lower frame 30 through the grate holes 91.

In addition, a steam supply pipe 7 for supplying steam to the fuel injection cone 31 in which fuel is stored is disposed below the rotary gear chamber 40. That is, a steam supply pipe 7 is provided below the lower frame 30 to supply steam for adjusting the equivalence ratio to enable complete combustion during combustion of the fuel F.

The steam supplied through the steam supply pipe 7 forms an OH group so that it does not generate CO to meet the fuel, thereby eliminating incomplete combustion. By making the equivalence ratio representing the mixing ratio of air and fuel to be suitable, SOx and NOx are not included in the combustion gas discharged to the upper side of the combustion chamber by assisting the complete combustion of the fuel F.

A fixed quantity supply pipe 51 and a fixed quantity supply hopper 52 for quantitatively supplying the fuel F to be burned to the fuel injection cone 31 inside the combustion chamber are configured under the lower frame 30.

The fuel transported through the metered feed hopper 52 is continuously supplied below the fuel injection cone 31, whereby the fuel F supported by the fuel injection cone 31 is stacked in a shape as shown. Is maintained.
