PLANT FOR DUST-FREE DISCHARGING OF COKE OUT OF OVENS OF COKE OVEN BANK Russian patent published in 2007 - IPC C10B33/00 

FIELD: coal-tar chemistry, protection of environment.

SUBSTANCE: at discharging coke out of oven of coke oven bank door-dismounting machine platform is mounted. On said platform plant having coke guide 3 with jacket 2 is arranged along axis of oven to be discharged and quenching car 15 is arranged under lower part of said platform between protection blinds 8. Simultaneously evacuation is created in dust and gas accumulator 10 communicated through branch pipe 12 with collector of system for removing dust and gas. Dust-gas mixture formed at supplying coke to quenching car 15 is entrapped upward by means of hot air flow. Comparatively large dust particles colliding to surface of lower part of platform are fallen into body of quenching car 15 while fine particles of dust trapped by hot air flow are moved along lower part of platform to slit openings from which they penetrate into horizontal air conduits 5. Out of air conduits 5 through air conduits 11 fine particles are fed to dust and gas accumulator 10 and through branch pipe 12 they penetrate to system for removing dust and gas. Dust-gas mixture penetrated to jacket 2 is fed to box 13 and then to dust and gas accumulator 10.

EFFECT: significantly reduced contamination degree of environment with harmful dust-gas outbursts, lowered metal consumption of door-dismounting machine.
