Are there any requirements regarding the drainage volume of the scrubber tower?
Of course, there is a need to control the liquid level in the scrubber tower.
The displacement should not be too low either; too low a value can lead to poor water quality and blockages in the sewage pipes. This is just my personal opinion, for reference only
Based on water quality analysis, it is necessary to replace the water regularly
First, ensure its liquid level by maintaining a certain discharge rate
The quality of water in the scrubber tower can affect water quality; a low circulation rate can lead to an increased dust content in the process gas. If the catalyst is exposed to the process gas for too long, it will deteriorate rapidly, and the pressure difference will also change. Additionally, the temperature at the outlet of the process gas will rise
The scrubber tower has two drainage paths: one leads to the system, and the other goes into the quench chamber of the gasifier. Are you asking about that route?
There definitely are; otherwise it will cause blockage of the quenching ring, and replacing it will affect the gas washing efficiency.

As long as it is possible to maintain control over the liquid level and the flash system can handle the volume, the drainage at the bottom of the scrubber tower should be increased as much as possible. The benefits go without saying.
The black water from the scrubber is primarily used to carry away the ash and residues present in the scrubber, thereby ensuring that the solid content in it remains low and preventing clogging of the filters. Its impact on the liquid level is not significant; in theory, the larger the amount, the better. However, the flash evaporation load must be taken into consideration, and it generally won’t be very high, as the amount of black water required by the gasifier is quite substantial
