The black water treatment system of water slurry pressurizing gasifying apparatus according to embodiments of the present invention and technological process, gasification furnace 1
By entering aeration tower 3 after valve regulated flow, the Heisui River of gasification furnace 1 and aeration tower 3 only needs to pass through gas washing in caused Heisui River
The aeration tower Heisui River outlet 36 of the bottom of tower 3 is continuously discharged into unit for treating water 4 by Valve controlling and handled, and changes current work
Unit for treating water 4 is removed in continuous discharge Heisui River simultaneously for gasification furnace and aeration tower in skill technology, and unit for treating water load is high, heat recovery
The shortcomings that efficiency is low；The gasification furnace black water discharge flow of existing process is to carry out being emitted into water process list according to the liquid level of gasification furnace
Member, and after implementing Heisui River flow of the present invention, the Heisui River of gasification furnace 1 is sent into aeration tower 3, only need to be from aeration tower 3 to water process list
Member 4 discharges Heisui River, and is discharged according to the concentration of buck in system, reduces discharge capacity so that unit for treating water 4
Load be reduced, the consumption of cooling medium is also reduced, and reduces the flow of high pressure ash water pump 6, reduce use
Electric consumption；The buck of blender 2 comes from high pressure ash water pump 6, and technique of the prior art is that the buck of blender carrys out self-loopa and washed
Water pump 5 is washed, it is therefore right due to circulating the water of washing water pump 5 from aeration tower 3 without the Heisui River by the processing of unit for treating water 4
The abrasion of equipment is of a relatively high, and the buck of the black water treatment system and handling process selection high pressure ash water pump 6 is after treatment
Buck, the abrasion of blender 2 is reduced first, next reduces the flow of circulation washing pump 5, reduces circulation washing pump 5
Power consumption.Whole system reduces the consumption of quantity of circulating water after implementing, reduce power consumption, system more saves.
