COMBINED METHOD OF SUCTION AND CLEANING OF COKE DELIVERY GASES, COKE CHAMBER TREATMENT GASES AND FORCED DEGRAPHITIZING OF THEIR RISERS AND ROOFS Russian patent published in 2002 - IPC

FIELD: by-product coke industry; methods and devices of dust-free delivery of coke from coke chambers; positive degraphitizing of risers and roofs. SUBSTANCE: method consists in suction of gases through risers by means of steam-jet ejectors fitted on tops of risers, delivery of steam from lines to nozzles of ejectors is performed by means of flexible rubber hoses connected to dispensing branch pipes during delivery of coke and treatment of coke chamber. Gases being sucked are cleaned in cyclone by means of air-jet ejector mounted on head of ejecting rod of coke pushing machine in parallel with chamber roof. Flow of delivery gases and sucked air which is directed to machine side is formed in under-roof space of coke chamber for degraphitizing coke chamber roof by jet of gases escaping from ejector diffuser; said jet is directed to roof by means of swivel blade. Large pieces of deposition fall on hearth of coke chamber. Fine particles and dust are ejected to cyclone for cleaning and directed flow of coke delivery gases from quenching car to riser of coke side is ensured by П-shaped extension-piece fitted with Ш-shaped baffle plate. EFFECT: possibility of combining gas cleaning procedure with graphite deposit removal. 2 dwg
