It is sprayed, flushing liquor and gas liquor flow to tar ammonia separator certainly through the tower tray that breaks；Hypomere water at low temperature section hypomere
The cycle flushing liquor that cycle flushing liquor pumping comes continuously sprays, and gas liquor flow to hypomere certainly with flushing liquor through primary cooler bottom
Sprinkling liquid bath, then through hypomere cycle flushing liquor be pumped to primary cooler water at low temperature section top recycle sprinkling；Extra condensate liquid by
It is sent to tar ammonia separator after cycle sprinkling liquid pump；The temperature of flushing liquor is recycled at 18~21 DEG C or so.Primary cooler at present
Preceding raw coke oven gas high temperature condensate liquid generally accesses primary cooler hypomere flushing liquor tank liquor envelope, coal dust, dust and tar slag in condensate liquid
Equal impurity have also accessed hypomere cycle flushing liquor system together.High temperature condensate liquid is cooled to the heat that cycle flushing liquor temperature is released
It is taken out of by water at low temperature in primary cooler water at low temperature section, consumes the dosage and primary cooler low-temperature zone heat exchange area of water at low temperature；Condensate liquid
In the impurity such as coal dust, coal dust and tar slag assemble in recycling flushing liquor system, lead to the blocking of equipment and pipeline, reduce
Water at low temperature section coal gas cooling effect；Extra condensate liquid is finally pumped to tar ammonia separator through hypomere cycle flushing liquor, increases
The sendout and power of cycle sprinkling liquid pump are added.The impurity such as coal dust, dust, naphthalene in high temperature condensate liquid are waste easily before primary cooler
Assemble in gas piping and Drainage pipe, causes raw coke oven gas pipeline section to be reduced, Drainage pipe blocks and coal gas transporting resistance increases
Add.
