Exhaust gas bring contaminant molecule is measured, needs the high concentrated water in this part being replaced as clear water when circulation fluid concentration reaches equilibrium concentration,
It is discharged into sump 8 by low temperature hc effluent is flashed by reflux pump 5 by switching flow, is disposed into sewage disposal link；
The superposition for avoiding the systemic contamination factor influences system steady production bring.
During exhaust gas carries out heat displacement heat exchange inside absorption tower 1, incondensable gas can be generated, this part is not cold
The disposition of solidifying gas is set by being sent into be concentrated by evaporation by pipeline under 1 top discharge pore plate of absorption tower and pressure-regulating valve control
Standby 9, it is further cooled down in evaporation concentration equipment 9, the non-condensation gas generated with evaporation concentration equipment 9 itself is by vacuum pump 10
Extraction system is collected through foul smell collector 11, is sprayed after being pressurized using injector 12, is sprayed by security implementation device fire arrester 13
Enter burner 14 and carries out innoxious burning disposition.
The setting of whole system links, the equipment of each key position are controlled by PLC or DCS system, it is ensured that each
The technological parameter of link executes stabilization, realizes fully absorbing for waste-gas heat, the efficient utilization of thermal energy, and finally innoxious
Disposition.
By process above, exhaust gas discharge thermal energy, which can be realized, fully absorbs reuse, and incondensable gas obtains burning processing, very
Harmlessness disposing is just accomplished.Heat exchange cycle hc effluent is discharged into collecting tank and enters the processing of waste water dis posal system, avoids existing system
Pollutant superposition accumulation bring of uniting runs hidden danger；It, can reuse saving about 3-5t/ of steam according to the operating condition of discharge waste hot steam
