Why does the sludge pool water need to be sent to the clarifier? Are there any process-related reasons?
Purify water quality, improve it... maintain the water quality of the system……
If the sludge pool water does not enter the sedimentation tank or the true flash tank, it will overflow on-site. Under normal circumstances, the sludge pool water does enter the true flash tank
I think there are 2 purposes. 1. The system pressure is not very high right after starting the vehicle. Before reaching high pressure, the water from the gasifier, tower scrubbers, and cyclones is sent directly to the true flash vessel. At this point, a portion of the water from the slag tank is directed to the clarification tank in order to prevent the vacuum flash vessel from filling up too quickly. 2. Shortly after the machine starts operating, both the high-pressure ash water pump and the low-pressure ash water pump begin to operate. As the load increases gradually, the water consumption also rises. At this point, some water from the slag tank is used to replenish the clarification tank, so that it can overflow normally into the ash water tank and prevent the level of water in that tank from dropping.
Isn’t it true that bringing everything into a vacuum flash vessel allows for better separation of acidic gases?
This is better! Our factory is designed this way, but some companies simply send it directly to the sedimentation tank! I think the impact of this shouldn’t be very significant, but it would be better to go into the real flash tank first and then send it to the sedimentation tank! ! :lol
The water in the slag pool comes mainly from the lockhopper and the lockhopper flushing tank; its temperature is relatively low, around 60 degrees. The temperature of the water in the clarification tank is also similar, generally around 40 degrees. Furthermore, there is relatively little dissolved gas in the slag pool water, so there is no need for it to enter the flash vessel. One route leads to the true flash vessel, which is generally used for adjusting the level of the true flash liquid; at other times, it leads to the clarification tank.
