発が要求されていた。On the other hand, recently, it has become necessary to simultaneously perform desulfurization and denitrification treatment, and therefore, it is being studied to arrange, for example, a dry exhaust gas treatment facility of an activated carbon moving bed type at the subsequent stage of a sintering machine. However, since the activated carbon moving bed type dry exhaust gas treatment equipment generates a higher pressure loss than the electric dust collector, it is necessary to add a large exhaust fan for the activated carbon moving bed type dry exhaust gas treatment equipment separately from the exhaust fan 23. In this case, at the time of start-up of the exhaust gas treatment, the suction negative pressure by the exhaust fan for the dry exhaust gas treatment facility (about -400 mmaq)
It is necessary to design equipment such as a duct and a damper that can withstand such a high suction negative pressure. Therefore, the operating pressure for normal exhaust gas treatment (about -10
There has been a demand for the development of a sintering exhaust gas treatment apparatus capable of safely operating with equipment such as a duct designed to be about 0 mmaq) and an operation method thereof.

ることもなく、安全に起動・運転を行えることとなる。Next, a method for operating the above-described sintering exhaust gas treatment apparatus will be described. First, at the time of start-up, the exhaust fan 4 on the side of the electric dust collector 3 is started with the air volume adjustment damper 5a installed in the exhaust fan 5 for the dry exhaust gas treatment facility closed and the air volume adjustment damper 7a in the bypass flue 7 opened. . Here, the sintering machine 1 is started up with the air volume adjustment damper 4a on the sintering machine 1 side fully opened. Next, while gradually opening the air volume adjustment damper 5a installed in the air exhaust device 5 for the dry exhaust gas treatment equipment so that the pressure between the two air exhaust devices 4 and 5 becomes constant, the air volume adjustment damper 7a in the bypass flue 7 is opened. Is automatically controlled so that is gradually closed. Thereby, the start-up of the sintering machine 1 can be advanced without causing a large fluctuation in the pressure between the two exhaust fans 4 and 5. Next, when it is confirmed that the sintering state of the sintering machine 1 is stable and the start-up is completed, the air volume adjusting damper 5a installed in the exhaust fan 5 for the dry exhaust gas treatment facility is fully opened, and the air volume adjusting damper in the bypass flue 7 is opened. 7a is operated to be fully closed. As a result, despite the activation of the exhaust fan 5 for the dry exhaust gas treatment facility, no large pressure fluctuation occurs between the two exhaust fans 4 and 5, and as a result,
A large negative suction pressure (approximately -400 mmaq) associated with the activation of the exhaust fan 5 for the dry exhaust gas treatment equipment does not act on the duct or the like. Therefore, the suction negative pressure (about -100 mmaq) at the time of normal exhaust gas treatment is always provided between the two exhaust fans 4 and 5.
Since it acts only to an extent, the duct can be safely started and operated without deformation or breakage of the duct.

に処理できていることが確認できた。DESCRIPTION OF THE PREFERRED EMBODIMENTS An operation method for restarting a sintering exhaust gas treatment apparatus having a configuration as shown in the figure after suspending it for periodic repair and restarting the apparatus was performed as follows. The exhaust fan 4 has a suction air volume 2
5000m 3 / min, boost capacity 1250mmaq, motor output 7
The exhaust fan 5 for 800 KWH, dry exhaust gas treatment equipment has a suction air volume of 25000 m 3 / min, a boosting capacity of 350 mmaq, and a motor output of 1600 KWH. First, the air volume adjustment damper 4a installed in the exhaust fan 4 and the air volume adjustment damper 5a installed in the air exhaust device 5 for the dry type exhaust gas treatment equipment have a minimum opening (0%), while the air volume in the bypass flue 7 With the adjustment damper 7a fully opened (100%), the exhaust fan 4 was started in this state. After the start-up was completed, the air volume adjustment damper 4a was gradually opened so that the current value of the blower 4 did not exceed a specified value (about 200 A) which took a safety margin from the rated current value. In this case, the exhaust gas temperature is in a steady state (about 100 ° C)
Since the temperature of the exhaust gas gradually decreases until the temperature of the exhaust gas decreases, and the current value of the exhaust fan 4 gradually decreases, the air volume adjustment damper 4a is gradually opened accordingly. Control can be either manual or automatic. Next, the exhaust gas temperature is 110 ° C. and the exhaust gas generation amount is 8
Since it was stabilized at 10,000 Nm 3 / h, it was judged that the start-up of the sintering machine 1 was completed, and the air volume adjustment damper 5a was set to the minimum opening (0%), and the air volume adjustment damper 7 in the bypass flue 7
The exhaust fan 5 for the dry type exhaust gas treatment equipment was started while a was fully opened (100%). After the start-up, the air volume adjustment damper 7
a was gradually closed. At this time, the air volume adjustment damper 5
For a, the opening was automatically adjusted by PID control so that the pressure of the pressure gauge 9 became a constant value (−50 mmaq). Next, the air volume adjusting damper 7a was set to the minimum opening degree (0%), and the entire amount of the sintering exhaust gas was guided to the dry exhaust gas treatment equipment 6 for processing. The SO x value of the sintering flue gas before being led to the dry flue gas treatment facility 6 was 185 ppm, but after introduction into the dry flue gas treatment facility 6 it dropped to 2 ppm, confirming that the sintering flue gas could be treated reliably. did it.
