Blockage in the inlet and outlet drip trays of the gasification slag tank pump
Thread Content
It didn’t pass the inspection before starting the pump; when the valve was opened, there was only fine debris inside. Is there a good way to avoid clogs?
It is mainly related to the quality of your coal. Additionally, delay the opening time of the butterfly valve in the slag tank, or increase the speed of the slag skimmer in order to reduce the amount of fine slag that reaches the clean water tank; also, carry out regular sewage discharge. . . . . . . . . . . . . .
Use a drain valve with a larger diameter; regular drainage is better
This backflow blockage is inevitable; what should be considered is the ease of clearing it once it occurs, by making the backflow section shorter and increasing its diameter
The inlet valve of the pump should be as close as possible to the slag bin； Increase the inlet duct diameter ； Slightly delay the timing at which the slag pool overflow valve is opened according to the slag discharge cycle.
Let’s gradually improve the new system; there are always some unreasonable designs.
Each time, delay the closing of the two valves in the slag tank, increase the speed of the slag skimmer, and make sure that the liquid level in the slag tank is not too low. .
If it is for exhaust, the drain pipe can be adjusted to point upward or at an angle; for waste discharge, a larger one has to be used
If it gets blocked, then it’s blocked – that place tends to get blocked anyway; just clear it when it gets blocked

The sludge pool pump’s drainage system is indeed unreliable, and the sludge is quite fine. I ran into it several times before; fortunately, it was easy to clear.
