In general, a combustion device is used in an industrial facility that requires industrial water, steam, or high temperature gas to generate thermal energy by igniting and burning fuel in a combustion cylinder to obtain thermal energy.

As the fuel used in such a combustion apparatus, solid fuels such as RDF fueled with household waste or RPF fueled with waste plastic are widely used in terms of economic efficiency and resource recycling.

Such a conventional combustion device is not only low combustion efficiency when the combustion is made only by the combustion air supplied from the blower, but also a large amount of dioxin, including dioxin, which is not completely burned due to incomplete combustion of various high calorie or low calorie and high humidity materials. Toxic substances are released into the atmosphere, causing air pollution and pollution around the world, causing serious social and environmental problems.

In order to solve this problem of the prior art, the region-specific centrifugal combustion apparatus using the flow of combustion air has been disclosed.

(Patent Document 1) KR10-1307795 B

In the case of Patent Document 1, the combustion air is injected into the combustion chamber at a constant pressure, and the combustion air must be injected at a high pressure for a long path moving downward while rotating inside the combustion chamber.

In particular, in the case of Patent Literature 1, a large amount of combustion air must be supplied through one air supply pipe, and the combustion air must be introduced into the air supply pipe at a very high pressure because it is divided into an upper supply pipe and a lower supply pipe and then introduced into the combustion chamber. There is a problem.

Furthermore, since a large amount of combustion air is supplied at one time, the moving speed of the combustion air is lowered in the combustion chamber, and the combustion air that descends while rotating along the combustion chamber inner wall does not reach the fuel at the bottom of the combustion chamber.

The present invention allows a plurality of combustion air to be introduced into the combustion chamber in a separate path, respectively, so that the combustion air each injected at a suitable pressure rotates a sufficiently long distance, so that the complete combustion of the combustion object can be effectively performed An apparatus is proposed.

Hereinafter, with reference to the accompanying drawings for the present embodiment will be described in detail. However, the scope of the inventive idea of the present embodiment may be determined from the matters disclosed by the present embodiment, and the inventive idea of the present embodiment may be implemented by adding, deleting, or modifying components to the proposed embodiment. It will be said to include variations.

1 is a view showing the configuration of a multi-centrifugal space divided combustion apparatus according to the present embodiment, Figures 2 and 3 are views showing the movement of combustion air in the multi-centrifugal space divided combustion apparatus of the embodiment.

First, referring to FIG. 1, in the combustion apparatus of the embodiment, combustion air is rotated by centrifugal force, and the flame fire pillar is formed in the inner cylinder 20 in which complete combustion is performed using this combustion air. Then, ashes generated by the combustion are moved to the lower side of the inner cylinder 20, the rotary gear chamber 40 is configured to rotate under the inner cylinder 20 to help the ash collection. In addition, the combustion air used for the combustion of fuel in the combustion chamber is discharged to the outside through the combustion air discharge unit 8 in the upper portion of the combustion chamber, and in some embodiments, the combustion air discharged through the combustion air discharge unit 8. Can be used to further heat other materials.

In detail, the combustion apparatus of the present invention includes an inner cylinder 20 and an outer cylinder 10 disposed to be spaced at a predetermined interval, and the outer cylinder 10 is formed in a shape surrounding the inner cylinder 20. In addition, since both the outer cylinder 10 and the inner cylinder 20 are configured to allow multiple combustion air flows, the width of the outer cylinder 10 and the inner cylinder 20 gradually increases from the top to the bottom, and has a stepped shape.

In the combustion apparatus of the present invention, combustion air gradually descends while rotating along the inner wall of the inner cylinder 20, and a combustion object continuously supplied below the inner cylinder 20 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 the present embodiment, the first to fourth combustion air inlet tubes are configured in the outer cylinder 10 so that the injection pressure of the combustion air supplied into the inner cylinder 20 is sufficient. That is, in order for the combustion air to rotate along the inner wall of the inner cylinder 20 and descend to the lower side thereof, the combustion air must be supplied to the inner cylinder 20 at a sufficient pressure, and when a large amount of the combustion air is supplied through one supply pipe. It will have to be supplied at a much higher pressure than if it were fed into a plurality of feed pipes.

On the contrary, in the present invention, since combustion air is supplied through the first to fourth combustion air supply pipes, the lower portion of the inner cylinder 20 is sufficiently lowered even if less pressure is used than when a large amount of combustion air is supplied to one supply pipe. Until the combustion air can move.

According to the present embodiment, the first combustion air supply pipe 1 is connected to the first position of the outer cylinder 10, and the second combustion air supply pipe 2 is connected to the second position, which is lower than the first position. Below the third combustion air supply pipe 3 and the fourth combustion air supply pipe 4 are connected, respectively.

Since the combustion air introduced through the first to third combustion air 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 air supply pipes ( 1,2,3) can be referred to as an upward feed pipe. Depending on the embodiment, a larger number of combustion air supply pipes may be constructed to further subdivide the required amount of combustion air.

On the other hand, since the combustion air which flowed in through the 4th combustion air supply pipe 4 descend | falls rotating the main flow path (refer FIG. 2), it can be called a falling supply pipe.

Since the size of the outer cylinder 10 to which the second combustion air supply pipe 2 is connected is larger than the size of the outer cylinder 10 to which the first combustion air supply pipe 1 is connected, the first combustion air supply pipe 1 is connected to the first combustion air supply pipe 1. The first combustion air flowing in and descending along the inner wall of the inner cylinder 20 is configured to smoothly descend.

In detail, referring to FIG. 4 together with FIG. 2, according to the present invention, a plurality of paths for supplying combustion air from the outside by forming a plurality of paths through which combustion air flows into the main flow path and then into the combustion chamber (inside the inner cylinder) are provided. The overpressure can be adjusted, and the combustion air introduced into the other path can be gradually joined while descending inside the combustion chamber, so that it can sufficiently descend while rotating to the fuel at the bottom of the combustion chamber.

The size of the inner cylinder 20a and the outer cylinder 10a of the position where the 1st combustion air supply pipe 1 comprised in the highest position was connected is the inner cylinder 20b of the connected position which is the 2nd combustion air supply pipe 2 comprised in the lower position. ) Is formed smaller than the size of the outer cylinder (10b). Because, as shown in Figure 4, there should be no obstruction in the falling of the air introduced into the combustion chamber through the first combustion air supply pipe (1), beneath the second combustion air supply pipe (2) In order to be able to smoothly merge with the air flowing into the combustion chamber, it is necessary to have such a stepped shape.

Similarly, when the combustion air supply pipe further configured to ascend in the main flow passage (see FIG. 2) is further configured, that is, when the third combustion air supply pipe 3 is further configured below the second combustion air supply pipe 2, 3 The size of the outer cylinder 10c and the inner cylinder 20c at the position where the combustion air supply pipe 3 is connected is larger than the size of the outer cylinder 10b and the inner cylinder 20b at the position where the second combustion air supply pipe 2 is connected thereon. Is formed larger.

Combustion air supplied through the first to third combustion air supply pipes 1, 2 and 3 rotates along a space (that is, a 'main flow path') 21 formed between the outer cylinder 10 and the inner cylinder 20. While rising, the direction of movement is changed by the blocking film 15 between the inner cylinder 20 and the outer cylinder 10 to be lowered. That is, the flow path is changed so that the combustion air rising while rotating along the main flow passage 21 is lowered while rotating along the inner wall of the inner cylinder 20 by the blocking film 15.

That is, when the combustion air flows into the main flow path, since the inflow direction of the combustion air coincides with the tangential direction of the outer wall of the inner cylinder 20 as shown in FIG. 2, the combustion air moves with a centrifugal force inside the main flow path 21. And the centrifugal force is moved to the inside of the inner cylinder 20 is preserved.

On the other hand, the induction nozzle 80 for smoothly moving the up or down while the combustion air flowing through the first to fourth combustion air supply pipe (1, 2, 3, 4) is rotated and the outer cylinder 10 and It may be configured between the inner cylinder (20). That is, referring to FIG. 3, in the case of the first to third combustion air supply pipes 1, 2, and 3, they are raised while rotating along the main flow path 21. The induction nozzle 80 may be configured in which a portion of the nozzle 81a formed in a strip shape is curved upward.

On the contrary, the combustion air flowing through the fourth combustion air supply pipe 4 is lowered while rotating along the main flow passage 21. In contrast to the shape of the induction nozzle shown in FIG. Induction nozzle can be configured that is bent downward.

On the other hand, in this embodiment, the combustion air supplied to the main flow passage 21 between the outer cylinder 10 and the inner cylinder 20 can be used as the outside air without being heated or cooled separately, the combustion air is rotated and the combustion object The temperature rises rapidly while descending to the phosphorus fuel (F). It is necessary to block the high temperature of the inner cylinder 20 which forms a combustion chamber from being transmitted to the outer cylinder 10, and it is necessary to cool the outer cylinder 10 which forms an exterior.

Since the combustion air uses the outside air, the combustion air flowing through the supply pipe has a relatively low temperature compared with the heated air inside the combustion chamber, so that the cooling of the outer cylinder 10 occurs naturally.

In addition, in this embodiment, the heat insulating material 11 and 12 are comprised between the outer cylinder 10 and the inner cylinder 20 in order to suppress that the high temperature of the inner cylinder 20 is transmitted to the outer cylinder 10.

In addition, a confirmation window 80 is configured in the outer cylinder 10 and the inner cylinder 20, and the user may directly check the situation inside the combustion chamber through the confirmation window 80.

On the other hand, under the inner cylinder 20, a cleaning blade 44 and a sweeper 45 for moving the ash generated after the combustion of the fuel F to the ash collecting cylinder 70 are configured, which is illustrated in FIG. A detailed configuration diagram of the rotating gear chamber of the present embodiment will be described.

 The clearance blade 44 and the sweeper 45 rotate around the fuel F and the combustion chamber with the rotation of the rotary gear chamber 40. This will be described later together with the accompanying drawings.

In addition to the first to fourth combustion air supply pipes 1, 2, 3, and 4, the rotary gear chamber cooling air supply pipe 5 and the chamber cooling air supply pipe 6 are further configured.

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 air is caused to move toward the rotary gear chamber 40 by its own weight. That is, the ash rotating together with the combustion air 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 in 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 air rotating inside the combustion chamber can naturally move 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.

The operation of the motor 42 causes the gear part 41 corresponding to the male gear to rotate, and the connecting member 48 connected to the rotating plate 47 together with the rotating plate 47 engaged with the gear part 41 also rotates in the combustion chamber. And it rotates about the fuel (F). The rotating plate 47 rotates around the fuel, that is, the outer cylinder 10 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 cleaning blade 44 serves to move the fuel attached to the combustion chamber bottom or the wall back to the center, and the sweeper 45 remains after combustion when the sweeper 45 rotates in a state close to the bottom of the rotary gear chamber 40. The ash falls to the removable duct 61 through the hole formed in the bottom surface.

In this way, the fuel (F) is burned by the combustion air heated to a high temperature inside the combustion chamber, the ash generated during the combustion grate 90 is formed in a shape surrounding the fuel (F) and the fuel injection cone (31) It moves toward the sweeper 45 through the grate hole of. Then, the clean combustion air, from which ash is removed through the grate 90 and the sweeper 45, rises along the center of the combustion chamber.

The lower frame 30 supports the rotary gear chamber 40 and the fuel injection cone 31 while forming the outer cylinder 10 and the inner cylinder 20 lower side. As shown in FIG. 6, the lower frame 30 includes a grate 90 for moving the ash contained in the rotating combustion air and moving outward by the centrifugal force to the rotary gear chamber 40.

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.

Meanwhile, referring to FIG. 1, 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 provided under the lower frame 30. Is configured on.

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.

In addition, the lower conveyance duct 61 for the ashes pushed by the rotation of the sweeper 45 to move the ashes to the ash collecting tank 70 through the hole in the bottom of the lower frame 30, and the re conveying duct The re conveying hopper 62 provided in 61 is comprised.

In addition, the ash is moved to the ash collecting cylinder 72 by the rotation of the re-transfer hopper 62, the ash collecting cylinder 72 is a pressure for preventing the ash overflows due to the difference between the internal pressure of the combustion chamber and the atmospheric pressure. An adjustment support bar 71 is configured. The pressure adjusting support bar 71 allows the ash to slowly fall to the bottom of the ash collecting chamber 70 while preventing the ash from being rapidly moved by the pressure difference between the combustion chamber and the ash collecting chamber 70.

7 is a view showing a configuration disposed around the outer cylinder.

The outer cylinder 10 of the upper side of the rotary gear chamber 40 has a sight glass 111 for checking the combustion chamber inner bottom and the fuel F, and an ignition burner for igniting combustion of the combustion air at the beginning when the combustion air is supplied ( 112 and at least one sensor 113, 114 for confirming the accumulation of fuel F are configured.

The sensors 113 and 114 can confirm the accumulation state of the fuel F, and can confirm the discharge state of the ash through the grate 90.

8 and 9 are views showing in detail the configuration in which the supply pipe is connected to the outer cylinder for smooth supply of combustion air according to the present embodiment.

In order to reduce the impact shock wave when the combustion air is supplied to the main flow passage 21 through the outer cylinder, the connection portion of the outer cylinder 10 and the combustion air supply pipe, that is, the cut-out shape of the outer cylinder 10 raises the combustion air and The case may be different from the case where it is intended to be lowered.

For example, in the case of the first to third combustion air supply pipes (1, 2, 3), the combustion air introduced into the outer cylinder rises while rotating. In this case, as shown in FIG. 8, the outer cylinder (10) The connecting portion of the combustion air supply pipe, that is, the opening 10h formed in the outer cylinder 10 may have a lower side (lower side) in a trapezoidal shape with a long side. The combustion air supply pipe 1 is formed with a rectangular opening 1a that is larger than the trapezoidal opening 10h.

That is, the combustion air moving along the combustion air supply pipe (1) exits through the opening (1a) of the supply pipe and gradually starts to enter from the lower part of the opening (10h) of the outer cylinder (10), and gradually the combustion air as a whole of the connection site. It should have an inflow shape. Through such a shape, the combustion air flowing into the outer cylinder 10 and the main flow passage has a path that gradually rises, and can be joined to the combustion air rising while rotating in the main flow passage without generating a shock wave.

On the contrary, as in the case of the fourth combustion air supply pipe 4, when it enters the main flow passage 21 and then rotates and descends, as shown in FIG. 9, the opening 10i of the outer cylinder (cut out portion) Is a trapezoidal shape in which the upper side is the long side, and the combustion air supply pipe 4 is formed with a rectangular opening 4a larger than the trapezoidal opening 10i.

According to the connection portion between the outer cylinder and the combustion air supply pipe, that is, the shape of the incision portion of the outer cylinder, the impact when the inlet combustion air is supplied to the main flow path between the outer cylinder and the inner cylinder can be reduced.
