Description of the Related Art Conventionally, exhaust gas discharged from a refuse incinerator for incinerating waste such as municipal waste and sludge is cooled by a cooler or an air preheater, and then, for example, by an electrostatic precipitator (EP). Although it had been treated for dust removal, the detection of organic chlorine compounds such as dioxins from the exhaust gas of a refuse incinerator that burns miscellaneous waste triggered the use of not only the electric dust collector but also a bag filter. The device came to be adopted.

In the figure, this exhaust gas treatment device includes a gas cooler 2, an air preheater 3 and a bag filter 4a, which are sequentially arranged in an exhaust gas flue 7 of an incinerator 1, and an induction blower 5 in the downstream of the bag filter 4a. The flue gas mainly composed of the chimney 6 and generated in the incinerator 1 is cooled by the gas cooler 2 and the air preheater 3, and a neutralizing agent for neutralizing the acid gas is added if necessary. After that, it flows into the bag filter 4a, and the solid content, the acidic component, and the like contained in the combustion exhaust gas are collected.

るおそれがある。By the way, in a refuse incinerator for incinerating miscellaneous wastes, the pressure in the incinerator suddenly increases due to a large change in the amount of refuse input, a rapid change in the waste quality, and a change in the water content. Therefore, not only various parts of the dust collector such as the filter cloth for the bag filter but also the bag filter device or the main body of the electrostatic precipitator itself may be damaged, leading to a large accident.

が不十分であった。However, the above-mentioned conventional exhaust gas treatment apparatus has not been provided with any measure against the rapid pressure fluctuation of exhaust gas. That is, for example, the bag filter device or the electrostatic precipitator has a characteristic that it is difficult to absorb the instantaneous pressure fluctuation of the exhaust gas, and the large-capacity one has a square shape, so that the pressure resistance design in the flat plate structure part becomes large. However, measures against rapid fluctuations in exhaust gas pressure were insufficient.

FIG. 1 is a diagram showing a system of an exhaust gas treating apparatus showing an embodiment of the present invention. This device comprises a gas cooler 2, an air preheater 3, a dust collector 4, an induction blower 5 and a chimney 6, which are sequentially provided in an exhaust gas flue 7 of an incinerator 1, the air preheater 3 and a dust collector 4. It is mainly composed of a bypass pipe 8 that connects the flue between the above and the flue of the downstream of the induction blower 5, and an exhaust valve 9 provided in the bypass pipe 8. FIG. 2 is an enlarged sectional view of the exhaust valve 9 provided in the bypass pipe 8 of FIG. This exhaust valve includes a casing 11 connected to the bypass pipe 8, a shield plate 12 provided substantially at right angles to the gas flow direction of the bypass pipe 8, and the shield plate 12 rotatable about the casing 11. A lock pin 16 for fixing the shield plate 12, a roller 15 for supporting the shielding plate 12 from below, an arm 14 to which the roller 15 is attached, and a pivot 13 for rotatably supporting the arm 14.
And a rod 17 connected to the other end of the arm 14.
And a counterweight 18 fixed to the tip portion of the rod 17, mainly. The counterweight 18 adjusts the operating pressure of the shielding plate 12 of the exhaust valve 9, and is normally set to operate at 250 to 300 mmAq. That is, in normal times,
The shield plate 12 is urged by the counterweight 18 to be closed, but when abnormal (high pressure), the shield plate 12 is opened to leak gas, and then automatically returns to the original state as the pressure decreases. In addition, 19 is an arrow which shows the flow direction of the high-pressure gas extracted by the bypass piping 8.

When a large amount of dust is thrown into the furnace and burns,
That is, the exhaust gas pressure rises sharply. The pressure on the upstream side of the dust collector 4 is the operating pressure of the exhaust valve 9, for example, 280 mmA.
When the value becomes equal to or more than q, the shielding plate 12 of the exhaust valve 9 is pushed to rotate downward around the stop pin 16 as an axis, and the high pressure gas leaks. The leaked high-pressure gas is introduced into the downstream flow of the induced draft fan 5 through the bypass pipe 8 and is discharged from the chimney 8 to the atmosphere. When the high-pressure gas leaks and the exhaust gas pressure of the flue 7 becomes equal to or lower than the set pressure of the exhaust valve 9, the arm 14 of the exhaust valve 9 rotates upward about the pivot shaft 13 and the roller 15 at the tip of the arm 14 moves. The shield plate 12 is pushed up to shield the bypass pipe 8. In this way, when the high-pressure gas leaks and the inside of the flue 7 returns to the normal pressure, for example, about -100 mmAq,
After that, the normal dust removal operation is continued.

で、通常の集塵操作を安定して継続することができる。According to the present embodiment, when the exhaust gas pressure in the flue 7 suddenly increases, the exhaust valve 9 provided in the bypass pipe 8 acts to leak the high-pressure gas, so that the high-pressure gas is discharged from the rear of the induction fan 5. Since it can be introduced into the flow, the dust collector 4 is not subjected to a pressure resistant design pressure, for example, a pressure of 500 mmAq or more, and damage can be prevented. In particular, when a bag filter device is used as the dust collector, damage to the filter cloth can be prevented in advance. After the high-pressure gas escapes, the exhaust valve 9 is closed and the inside of the flue 7 returns to the normal pressure, so that the normal dust collecting operation can be stably continued.

その後、通常の集塵操作が継続される。In this embodiment, the amount of high-pressure gas that leaks from the exhaust valve 9 and is introduced into the wake of the induced draft fan 5 is the minimum necessary for returning the pressure in the flue 7 to the normal pressure, and remains as it is. Although it does not cause air pollution or the like even if it is released into the air, it may be treated separately. FIG. 3 is a partial detailed view showing another embodiment of the present invention. This device connects the water sealing pipe 21 to the casing of the bag filter 4a, introduces the tip of the water sealing pipe 21 into the water sealing tank 22 to seal the water, and keeps the water level of the water sealing tank 22 constant at all times. The water supply pipe 23 is provided. With such a configuration, when the pressure of the flue 7, that is, the pressure inside the casing of the bag filter 4a rises above a set value, the water sealing pipe 21
Is released, the high-pressure gas leaks, and the gas pressure in the flue 7 decreases. At this time, the sealing water in the sealing water tank 22 overflows, but since the amount of water is kept constant by the water supply device (not shown) connected to the water supply pipe 23, the water sealing effect is restored,
After that, the normal dust collecting operation is continued.

The dust collection operation of can be stably continued. In the present embodiment, the water sealing pipe 22 and the water sealing tank 23 are preferably installed outdoors. This allows the leaking high-pressure gas to be released to the atmosphere as it is. Since the amount of gas discharged from the water sealing pipe 21 is the minimum necessary for reducing the pressure of the flue that has temporarily risen, there is no possibility of expanding air pollution without special treatment. In this embodiment, the water sealing tube 22 needs to be connected to the casing on the upstream side of the filter cloth.

Example 1 A bag filter device is used as the dust collector 4 for the exhaust gas discharged from the refuse incinerator 1 that incinerates municipal solid waste input at 3 t / hr, and the working pressure of the exhaust valve 9 (counterweight 18) is set to 250 mmAq. When continuously treated with the set exhaust gas treatment equipment of Fig. 1, when stable, the furnace pressure is -1.
00mmAq, gas cooler 2 outlet pressure is -150mmA
q, the upstream pressure of the bag filter was -200 mmAq, and the downstream pressure of the bag filter was -400 mmAq.
After that, since the amount of dust thrown into the incinerator 1 temporarily increased, the internal pressure of the furnace rose to 300 mmAq, and the differential pressure between the bag filter inlet and the induced blower 5 outlet was 250 mmA.
Since it became q or more, the exhaust valve 9 actuated and the high-pressure gas leaked. The flue pressure after the high-pressure gas leaks is -2
After returning to 00 mmAq, the normal dust collecting operation could be stably continued.
