WET EXTINGUISHING SYSTEM FOR COKE

PURPOSE:To provide the titled system where the water vapor and gas generated containing dust formed in a coke extinguishing chamber is subjected to water spray treatment, thus eliminating problems with dust and odor caused by the exhaust gas, leading to exhaust fan of smaller size, enabling heat recovery from the cooling water, etc. CONSTITUTION:The water vapor and the gas generated containing the dust formed in a coke extinguishing chamber 15 is introduced into a quencher 8, being washed with a water spray means 10. Said water vapor is converted into water droplets, being introduced, through a discharge outlet 16, into a water treatment device 16 together with the sprayed water with the dust, etc. accompanied. The remaining gas generated is discharged, through an exhaust fan 9, into the air, with the dust and odor removed. Furthermore, heat recovery can be done from the water discharged from the quencher 8.
