Reach more than 0.25MPa (G).When the operating load of methanol/water knockout tower is relatively low, and LV7619 aperture is less, E7620 will appear from
Significantly liquid hit phenomenon, especially at its shell side inlet, performance is even more serious.Nearly 3 years, using maintenance when to E7620 manage
Bundle implements four plugging operation, but its damaged condition of later stage is excessive, can not meet the requirement of normal process conditions completely, in
Be by integral replacing, this not only adds additional the operating cost of device, and have impact on system " peace, steady, long, full,
Excellent " running environment.Analysis reason, mainly due to methanol/water knockout tower hot waste water through LV7619 throttling, after blood pressure lowering,
Part vaporizes, therefore is carrying out, in heat transfer process, leading to E7620 liquid hit phenomenon with E7620 tube side recirculated water.
Utility model content
The purpose of this utility model be provide a kind of methanol/water knockout tower waste water drainage system, solve existing in coal slurry
Present in pressurized gasification preparation methanol process, liquid hit phenomenon leads to device damage serious, the high problem of maintenance cost.
This utility model be employed technical scheme comprise that, a kind of methanol/water knockout tower waste water drainage system, including methanol/
Water separation column, methanol/water knockout tower discharge of wastewater pipeline is provided with gaseous effluent cooler, gaseous effluent cooler and discharge of wastewater outlet
Between be additionally provided with fluid level control valve.
Feature of the present utility model also resides in,
It is additionally provided with stop valve A, between stop valve A and gaseous effluent cooler between methanol/water knockout tower and gaseous effluent cooler
It is also associated with wherein one end of stop valve B, stop valve B is in parallel with the two ends of methanol/water knockout tower discharge of wastewater pipeline junction point
It is provided with shutoff valve C.
It is additionally provided with stop valve D, fluid level control valve and discharge of wastewater export it between gaseous effluent cooler and fluid level control valve
Between be also disposed with stop valve E and stop valve F, be also associated with wherein the one of stop valve G between gaseous effluent cooler and stop valve D
End, is also associated with wherein one end of stop valve H between fluid level control valve and stop valve E.
It is also associated with stop valve I between stop valve D entrance point and the port of export of stop valve E.
Fluid level control valve model LV7619.
Gaseous effluent cooler model E7620.
The beneficial effects of the utility model are that a kind of methanol/water knockout tower waste water drainage system, to methanol/water separation
After LV7619 installation site implements transformation on tower 1 discharge of wastewater pipeline, send throttling at LV7619 for the waste water outside, pressure reduction will
Occur after it carries out heat exchange with E7620 tube side recirculated water, temperature now is reduced to less than 40 DEG C, therefore inherently eliminates
There is the possibility of vaporization in waste water.
