Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator charging apparatus for an incinerator, which is suitable for charging an incinerator into a combustion chamber.

[0002]

2. Description of the Related Art Generally, various incinerators for incinerating incinerated materials such as household waste and industrial waste are known.

Conventionally, a relatively medium-scale incinerator installed in a company or a hospital has a combustion chamber (primary combustion chamber) provided with a combustion burner and an air supply unit. At the time of use, the opening / closing door of the charging port is opened to inject the incineration material directly into the combustion chamber, ignite the combustion burner, and incinerate while supplying air from the air supply unit. Also, when adding additional incinerated materials, open the opening and closing door of the inlet,
Additional combustion objects are sequentially charged into the combustion chamber during combustion.

[0004]

However, harmful substances, such as dioxins, which are generated when burning plastics and the like and give ecosystems, have become a social problem. The cause of the generation of such harmful substances is incinerators. Often due to the performance and structure of the. In general, dioxin is decomposed at a high temperature of 800 ° C. or more, so that it is possible to suppress the generation of harmful substances such as dioxin in terms of performance.

However, in the conventional incinerator, since the operator opens the opening / closing door and directly puts the incineration material into the combustion chamber (primary combustion chamber), the worker receives heat directly from the charging port. A problem arises in that harmful substances such as dioxins generated from incinerated materials that are not completely incinerated in the primary combustion chamber leak out from the inlet. In particular, this problem cannot be ignored from the viewpoint that not only harmful substances are released into the atmosphere, but also the amount of harmful substances inhaled by workers increases and the working environment deteriorates. In addition, it is conceivable that the harmful substance hardly leaks to the outside by adopting a double door system or the like. However, it is not possible to completely prevent the leak from the input port due to an operation error of an operator or the like.

[0006] The present invention has been made to solve the problems existing in the prior art, and reliably prevents leakage of harmful substances such as dioxin from an inlet and minimizes adverse effects on the natural environment. In addition, it is an object of the present invention to provide an incinerator material charging device for an incinerator that can further improve the working environment of a worker.

The control unit 9 is connected to the limit switches 5s and 6s on the input side, and connected to the drive units 25 and 31 and the display unit 38 on the output side. In this case, since the control unit 9 controls the driving of the driving units 25 and 31, if the limit switch 6s detects the open state, the driving of the driving unit 25 is stopped, that is, the outside door 3 is locked at the closed position Pc. In addition to configuring the door lock function unit 7, when the limit switch 5s detects the open state, the drive unit 31 stops driving, that is, configures the inner door lock function unit 8 that locks the inner door 4 to the closed position Qc. The control unit 9 controls the driving units 25 and 31 and the air cylinder 35.
Sequence control is performed according to a preset control program. The state of each unit during the sequence control is displayed on the display unit 38 by a display lamp or the like.

Next, the method of use and operation of the incinerator charging apparatus 1 will be described with reference to the flowchart shown in FIG. 6 and FIGS. 1 to 4, and the operation of the entire incinerator will be described with reference to FIG. explain.

First, in a normal state, since the outer door 3 and the inner door 4 are at the closed positions Pc and Qc, respectively, both the limit switches 5s and 6s detect the closed state, and the outer door lock function section 7 and the inner door lock function are performed. All the units 8 are in the unlocked state.

Therefore, when the start switch is turned on, the drive section 25 is driven and controlled by the control section 9, and the outer door 3 is controlled.
Moves to the open position Po shown in FIG. As a result, the entrance 2i is opened, and the worker accommodates the incineration material B from the entrance 2i into the charging duct 2 (step S1).
~ S4). Then, when the start switch is turned on, the drive unit 25 is drive-controlled by the control unit 9, the outer door 3 moves to the closed position Pc (FIG. 4), and the entrance 2i is closed (step S5). Thereafter, automatic processing is performed according to the sequence control by the control unit 9.

When the start switch is turned on, if the inner door 4 is not at the closed position Qc due to a failure of the inner door 4 or a part of the incineration object B inserted last time, the open state is detected by the limit switch 6s. Control unit 9
Performs a lock process of locking the outer door 3 to the closed position Pc by the outer door lock function unit 7 (steps S1, S2, S
6). That is, the control unit 9 stops the drive control for the drive unit 25 and displays that an abnormality has occurred using a display lamp or the like on the display unit 38. In this case, the operator performs necessary inspection processing. For example, if the purging process is performed, the inner door 4
An abnormality in which a part of the incinerated material B is caught can be eliminated. In the purging process, by turning on the purge switch, the inner door 4 is opened while the outer door 3 is closed, and the pushing device 11 is moved forward and backward one to several times, and then the inner door 4 is closed. Thereby, if the inner door 4 moves to the closing position Qc, the limit switch 6s
, The lock process by the outer door lock function unit 7 is released, the drive unit 25 is driven and controlled by the control unit 9, and the outer door 3 moves to the open position Po shown in FIG. (Steps S7, S3).

On the other hand, according to the sequence control, the control unit 9
The inner door 4 moves (ups) to the open position (fully open position) Qo shown in FIG.
Is released (steps S8 to S10). Next, the drive of the pressing device 11 is controlled by the controller 9 (step S1).
1). Thereby, the push plate 37 advances to the most advanced position,
The incinerated material B is pushed into the combustion chamber C and then retracted to the home position (step S1).
2). FIG. 4 shows a state in which the push plate 37 has moved forward. And
When the loading of the incineration material B by the pushing device 11 is completed, the drive unit 31 is driven and controlled by the control unit 9, and the inner door 4 is moved to the position shown in FIG.
And the outlet 2o is closed (step S13).

When the inner door 4 is opened, if the outer door 3 is not at the closed position Pc due to a failure of the outer door 3 or a part of the incinerator B inserted last time, the limit switch 5s
, The control unit 9 performs a lock process of locking the inner door 4 to the closed position Qc by the inner door lock function unit 8 (steps S8, S9, S14). That is, the control unit 9 stops the drive control for the drive unit 31 and displays that an abnormality has occurred by a display lamp or the like on the display unit 38. In this case, the operator performs necessary inspection processing. If the abnormality is removed by the inspection processing and the outer door 3 moves to the closed position Pc, the closed state is detected by the limit switch 5s, so that the lock processing by the inner door lock function unit 8 is released and the control unit 9 The drive unit 31 is driven and controlled, and the inner door 4 moves to the open position Qo shown in FIG. 4 (steps S15 and S10).

The above is one cycle of the charging process. Thereafter, based on the detection result such as the preset interval time or the temperature state of the primary combustion chamber C, a display for permitting the introduction of the next incineration material B is displayed on the display device 38.
The operator may turn on the start switch after checking the display, whereby the outer door 3 moves to the open position Po (step S1 ...). Therefore, when the incineration material B is charged, the outside (operator) and the combustion chamber C are always shut off, so that even when the primary combustion chamber C is burning, leakage of harmful substances such as dioxin to the outside is ensured. Will be blocked.

On the other hand, the incineration process of the incineration material B charged into the primary combustion chamber C is performed as follows. Note that, in FIG. 9, an arrow W indicates a charging path of the incinerated material B.

First, the incineration material B is primarily incinerated in the primary incineration chamber C. In this case, the primary combustion burner 53 is ignited, and air is supplied from the plurality of air supply units 54. At this time, the temperature of the primary combustion chamber C is heated to 800 ° C. or more. Note that the incineration ash Mf is accumulated in the incineration ash storage chamber Ca through the roaster 51.

On the other hand, exhaust gas (smoke) generated during incineration is:
The air is sucked toward the chimney 67 by the operation of the blower 68. In FIG. 9, arrow F indicates the direction of the airflow. Therefore,
The exhaust gas in the primary incineration chamber C flows into the secondary combustion chamber Cs through the conduit 56. In this case, the exhaust gas passing through the conduit 56 is heated by the two secondary combustion burners 53 and 53 and is secondarily incinerated in the cyclone type secondary combustion chamber Cs. Thereby, harmful substances such as dioxin are completely decomposed. In the secondary combustion chamber Cs, a part of the dust falls into the neutralized liquid stored at the bottom.

Further, the exhaust gas in the secondary combustion chamber Cs flows into the dust collection tower 58 through the smoke conduit 61. In the dust collecting tower 58 of the scrubber type, dust in the exhaust gas is removed by the shower (neutralizing solution) injected from the shower unit 62, and the exhaust gas is cooled. The exhaust gas from which the dust has been removed flows into the dehumidification tower 59, and after the moisture in the exhaust gas has been removed, is discharged from the chimney 67 to the atmosphere. Also,
The shower sprayed from the shower units 62 and the water (water droplets) removed by the dehumidifying tower 59 fall into the neutralization tank 60.

When the incineration process is completed, water is sprayed from the water spray device 52 to the incinerated ash Mf stored in the incinerated ash storage chamber Ca. Thereby, when taking out the incineration ash Mf outside, for example, even if the wind is strong, scattering of the incineration ash Mf is prevented. Further, dust Ms in the neutralization liquid in the neutralization tank 60 is collected by the dust collection device 69. That is, the dust Ms precipitates in the dust sedimentation tank 70, and the sedimented mud-like dust Ms is collected in a collection tank (not shown) by the rotation of the screw 71s in the discharge mechanism 71.

On the other hand, FIG. 5 shows an incineration object charging apparatus 1 according to a modified embodiment of the present invention. In the embodiment shown in FIGS. 1 to 4, an example is described in which the incinerator B accommodated in the charging duct 2 is pushed and charged into the combustion chamber C by providing the pressing device 11 in the charging duct 2. In the example, the charging duct 2 is provided so as to be inclined so that the incinerated material B accommodated in the charging duct 2 falls into the combustion chamber C by its own weight. Therefore, in the modified embodiment, the pushing device 11 becomes unnecessary. Although the embodiment shown in FIGS. 1 to 4 has described an example in which automatic processing is performed, the modified embodiment shows a case in which the outer door 3 and the inner door 4 are manually opened and closed.

The outer door 3 in the modified embodiment has a hinge 4
1 to be rotatably mounted on the upper surface of the input duct 2 and to have the handle portion 42 so as to be opened and closed manually. The inner door 4 is slidably guided up and down by a cover member 43 provided above the input duct 2 and a guide passage 44 formed by one end of the input duct 2, and is manually operated by an operation mechanism 45 including a pulling wire 45 w and the like. Can be opened and closed. Further, an outer door sensor 5 and an outer door lock function unit 7 on the outer door 3 side and an inner door sensor 6 and an inner door lock function unit 8 on the inner door 4 side are provided on the upper surface of the input duct 2. Set up. In FIG. 5, the same parts as those in FIG. 1 are denoted by the same reference numerals to clarify the configuration, and a detailed description thereof will be omitted.

Thus, at the time of loading, first, the outer door 3 is opened artificially, and the incinerated material B is accommodated in the charging duct 2 from the entrance 2i. After the outer door 3 is completely closed, the operating mechanism 45 is operated to raise the inner door 4 to the open position. As a result, the outlet 2o is opened, and the incineration material B accommodated in the charging duct 2 falls into the primary combustion chamber C by its own weight.

On the other hand, when the operator opens the outer door 3 and the inner door 4 is not at the closed position, the open state is detected by the inner door sensor 6. Mechanically locked in the closed position. As a result, the outer door 3 cannot be opened. If the abnormality is removed by inspection or the like and the inner door 4 is set to the closed position, the closed state is detected by the inner door sensor 6, so that the lock by the outer door lock function unit 7 is released and the outer door 3 is opened. Can be. Therefore, the worker moves the incinerated material B from the entrance 2i to the charging duct 2
Can be housed inside. Further, when the inner door 4 is opened, if the outer door 3 is not in the closed position, the open state is detected by the outer door sensor 5, so that the inner door 4 is mechanically moved to the closed position by the inner door lock function unit 8. Locked. As a result, the inner door 4 cannot be opened. Then, if the abnormality is removed by inspection or the like and the outer door 3 is set to the closed position, the closed state is detected by the outer door sensor 5, so that the lock by the inner door lock function unit 8 is released and the inner door 4 is opened. Can be.

Therefore, also in this case, when the incineration material B is charged, the outside (operator) and the combustion chamber C are always shut off. Therefore, even if the primary combustion chamber C is burning, dioxin and the like to the outside are not affected. Harmful substances are reliably prevented from leaking.

The embodiment has been described in detail above.
The present invention is not limited to such an embodiment,
The configuration, shape, material, quantity, etc. of the details can be arbitrarily changed, added, or deleted without departing from the gist of the present invention. For example, the outer door 3 and the inner door 4 which are manually opened and closed as shown in FIG. 5 may be applied to the embodiment shown in FIG. 1, or the drive shown in FIG. 1 may be applied to the modified embodiment shown in FIG. Parts 25, 3
The outer door 3 and the inner door 4 that are opened and closed by the first door 1 may be applied.
The embodiment shown in FIG. 1 includes an outer door 3 which is manually opened and closed as shown in FIG.
And when the inner door 4 is applied, instead of the air cylinder 35 in the pushing device 11, the pushing plate 37 can be artificially advanced and retracted by an operating rod protruding outside from the end face of the input duct 2. Is also good. Further, the work of accommodating the incinerated material B from the inlet 2i into the charging duct 2 may be automated by a pit crane method or the like, or the inside of the charging duct 2 may be a miniaturization processing device, a stirring processing device, a transfer device, etc. Various peripheral devices can be built in.

[0041]

As described above, the incinerator input apparatus for an incinerator according to the present invention has an inlet section and an outlet section, and a charging duct provided with the outlet section facing the combustion chamber; The outer door that opens and closes, the inner door that opens and closes the outlet, the outer door sensor that detects the open / closed state of the outer door, the inner door sensor that detects the open / closed state of the inner door, and the outer door can be locked in the closed position An outer door lock function, an inner door lock function that can lock the inner door to the closed position, and an outer door lock function that locks the outer door to the closed position if at least the inner door sensor detects an open state, When the outer door sensor detects the open state, the control unit locks the inner door to the closed position by the inner door lock function unit, so that the following remarkable effects are obtained.

Since the combustion chamber is always shut off from the outside (operator) when the incineration material is charged, leakage of harmful substances such as dioxin to the outside is reliably prevented even when the combustion chamber is burning. Adverse effects on the natural environment can be minimized.

In any situation, the worker does not directly receive the heat of the combustion chamber, so that the working environment of the worker can be further improved.
