Pipeline condenses liquid processing device.
Background technique
During reclaiming clean coke-oven gas, the raw coke oven gas escaped from coke furnace carbonization chamber through tedge first through bridge tube into
Enter gas collecting tube, is cooled to 80~84 DEG C by the cyclic ammonia water that tar ammonia separator is sent.Gas collecting tube outlet raw coke oven gas and
Tar ammonia mixture is after gas-liquid separator, tar ammonia mixture tar removing ammonium hydroxide separator；Raw coke oven gas enters just cold
Device continues cool to 20~22 DEG C.Raw coke oven gas after gas-liquid separator is entrained with the impurity such as coal dust, tar and naphthalene to some extent；
High temperature raw coke oven gas pipeline is not kept the temperature before primary cooler, and with environment heat transfer process, saturation water condensation gets off to form height in raw coke oven gas
Warm condensate liquid, condensate temperature is close to 80~84 DEG C of raw gas temperature；The impurity such as part coal dust, tar and naphthalene also enter cold together
Lime set.Primary cooler generallys use the indirect primary cooler of transverse tube, carries out sub-sectional cooling to raw coke oven gas with industrial circulating water and water at low temperature.It is right
Needing to recycle the user that raw coke oven gas waste heat generates high-temperature residual heat water, upper section, middle section, lower section three-stage structure can be used in primary cooler, on
Section is cooling with remaining hot water.Disconnected tower tray is set between primary cooler recirculated water section and water at low temperature section.For strengthen primary cooler heat exchange efficiency,
Improve the de- naphthalene efficiency of primary cooler, the tar ammonia emulsion that remaining hot water section, recirculated water section are sent with tar ammonia separator
It is sprayed, flushing liquor and the disconnected tower tray of gas liquor warp flow to tar ammonia separator certainly；Lower section water at low temperature section lower section
The circulation flushing liquor of circulation flushing liquor pumping continuously sprays, oneself flow to lower section through primary cooler bottom for gas liquor and flushing liquor
Sprinkling liquid bath, then through lower section circulation flushing liquor be pumped to primary cooler water at low temperature section top circulation sprinkling；Extra condensate liquid by
It send after circulation sprinkling liquid pump to tar ammonia separator；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 lower section flushing liquor tank liquor envelope, coal dust, dust and tar slag in condensate liquid
Equal impurity have also accessed lower section circulation flushing liquor system together.High temperature condensate liquid is cooled to the heat that circulation flushing liquor temperature is released
It is taken out of in primary cooler water at low temperature section by water at low temperature, 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 circulation 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 lower section circulation flushing liquor, increases
The sendout and power of circulation 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 blocking and coal gas transporting resistance increase
Add.
