In the figure, reference numeral 1 denotes a belt conveyor connecting portion, which is a portion where the coal 12 transfers from the upstream belt conveyor 3 to the downstream belt conveyor 4. Transit section 1
In this case, the coal 12 drops, and the pulverized coal contained in the coal becomes dust and scatters. Therefore, the hood 5 is provided.

場に送られ、燃料として使用される。In order to reduce dust generation at the transit section 1 and to prevent dust from piles of coal carried by a belt conveyor and piled up, the maximum amount of coal transported per transit section is increased. Watering about 1%. For example, when the transport amount of coal is 3000 t / h, 30 t / h of water is sprinkled. Sprinkling is performed aiming at the coal 12 that drops from the chute sprinkling shower 2 at the connecting portion. Meanwhile conveyor belt 3
Since pulverized coal adheres to the surface of the scraper 11
Although it is scraped off by a, it does not drop sufficiently in a dry state, so cleaning water is applied to the return side 3a of the conveyor belt by the cleaning shower 6a. After applying the cleaning water, the scraper 11b is used to scrape off the moist deposits. 7 is a recovery hopper for recovering the washing water. The upper surface of the hopper 7 is cleaned by the cleaning shower 6b. The wash water flows from the recovery hopper 7 through the strainer 8 into the drain pit 9. A drainage pump 10 sends the wash water from the drainage pit 9 to the wastewater treatment device. The wastewater treatment device is composed of a coagulation stirring tank, a coagulation sedimentation tank, a sludge dewatering device, etc. The treated water is reused, and the sludge is dewatered and sent to a coal storage yard for use as fuel.

くかかる。In the conventional sprinkler cleaning device for the transfer section of the conveyor described above, the cleaning water has an SS (amount of suspended solids) of about 5000 ppm and the flow rate is 1/4 to 1 of the chute spraying shower flow rate. It is / 5 and cannot be discharged as wastewater as it is, so wastewater is treated.
However, a large amount of coagulant is required for wastewater treatment, and transportation costs for transporting the dehydrated sludge to the coal storage yard are high, resulting in a large running cost. Further, since the collected water having SS of about 300 ppm is conventionally used for watering the chute, the running cost of the pump for collecting the collected water is high.

Therefore, the load on the waste water treatment equipment is reduced, the running cost is reduced, and the running cost of the water feed pump for sending water to the chute sprinkling shower is reduced. The purpose is to reduce.

After confirming that there is coal on the conveyor, open the watering shower control valve and start watering the chute watering shower. After entering the steady operation, the drainage control valve is closed and the communication control valve is opened to send the wash water to the chute sprinkling shower without sending it to the wastewater treatment equipment. At this time, throttle the spray shower control valve so that the flow rate of the chute spray shower does not increase too much. Since the wash water is used for the sprinkling shower in this way, the load on the wastewater treatment device is reduced and the running cost of the wastewater treatment device is reduced. Also, since the sprinkling shower control valve is throttled, the load on the pump that sends water to the sprinkling shower is also reduced.
