Abstract
A shed encloses a coke wharf onto which hot coke is pushed, the coke cake passing through a coke guide into the shed. Doors in the shed are disposed opposite the coke oven chambers and each door is openable when a coke guide is positioned at an oven to be pushed. Deflector means are located inside the shed at each door that break up and spread the coke onto the coke wharf. Fumes that evolve from the coke on the wharf as it is being quenched are collected in a main. An auxiliary collecting main and hood structure are located above the coke oven doors, whereby effluent arising from coke in the chambers after the oven doors are removed are collected in the auxiliary collecting main and conducted thence into the collecting main.
Claims8
In apparatus for quenching hot coke pushed from coke oven chambers through a coke guide onto a coke wharf from which the quenched coke is removed by a rotary plow and a belt conveyor, the combination with said coke wharf of:
- a. an enclosure covering said coke wharf and having doors in said enclosure opposite said coke oven chambers;
- b. means on said coke guide for opening and closing a door in said enclosure when said guide is aligned with a coke oven chamber to be pushed;
- c. at least one movable structure within said enclosure that carries nozzles that emit water for quenching said coke as it falls onto said wharf;
- d. means at each door within said enclosure for deflecting said coke as it passes therethrough;
- e. means for collecting and removing effluent from said enclosure when coke is quenched within said enclosure;
- and
- f. means supplying said water to said nozzles.
In apparatus for quenching hot coke pushed from coke oven chambers through a coke guide onto a coke wharf from which the quenched coke is removed by a rotary plow and a belt conveyor, the combination with said coke wharf of:
- a. an enclosure covering said coke wharf and having doors in said enclosure opposite said coke oven chambers;
- b. a pinion operated rack on said coke guide that engages a protrusion on a door in said enclosure whereby, when said coke guide is opposite a coke oven chamber to be pushed, said pinion operated rack moves and opens a door opposite said chamber to be pushed;
- c. a frame that is movable within said enclosure carrying nozzles from which water is sprayed onto hot coke as it is pushed into said enclosure;
- d. a plurality of deflector plates within the enclosure arranged vertically alongside each such door;
- e. a first collecting main communicating with said enclosure for receiving and removing effluent from said enclosure;
- f. a second collecting main above said coke oven chambers that collects effluent from said chambers when doors thereon are removed preparatory to pushing coke from said chambers;
- g. at least one conduit communicating with said first collecting main and said second collecting main;
- h. means within said enclosure that coacts with coke entering said enclosure and activates the flow of water from said nozzles;
- and
- i. means supplying water to said nozzles.
