Description
Technical field
The present invention relates to coking field more particularly to a kind of methods and dress for improving transverse pipe initial cooler circulating condensing liquid quality
It sets.
Background technique
See Fig. 1, drum cooling working procedure transverse pipe initial cooler some processes:
1,5 transverse pipe initial coolers in parallel are to recycle the cooling first set key device for cleaning coal gas in operation area, before device~
80 DEG C of raw coke oven gas is cooled to 18 DEG C~22 DEG C after device.Coal gas enters from top, restrains inside primary cooler with cooling water,
Upper section uses circulating water, and lower section uses the cooling coal gas of water at low temperature.5 primary cooler gas exits collect temperature i.e. " set temperature
Degree " is the key process parameter for recycling operation area drum cooling working procedure, directly affects the operating condition of this process and subsequent handling.
2, the low melting points such as naphthalene, acenaphthene for carrying secretly in raw coke oven gas fraction easily causes primary cooler shell side to block, and increases coal gas conveying
Resistance, so primary cooler up/down section persistently sprays condensate liquid and cleans coal gas, the condensate liquid after spraying coal gas by primary cooler/
Lower section reflux line initially enters corresponding gas liquor sealing groove, then flowing full it is supreme/lower section condenses liquid bath, finally use up/down section
