Abstract
Abstract Apparatus for quenching coke without polluting the surrounding atmosphere, wherein a coke guide carriage has a conveyor-belt floor for transferring coke from an oven to a quench car through a tubular guide, and the quench car being contained within a hood having top, end, and side walls for confining smoke, fumes, and dust generated by the movement of the coke from the oven to the quench car; the hood including a sprinkling system for spraying water onto the coke in the quench car and the hood including vent means in the top wall which vent means includes a stack having a gas inlet end that is enclosed within a gas plenum chamber having a water sprinkling system therein for providing a curtain of water around the inlet end for washing the gas as it enters the stack, whereby the conveyor belt, the sprinkling system and the vent cooperate to minimize any smoke and dust created.

Claim 1
Independent Claim
199 words
Apparatus for preventing air pollution during discharge of coke from coke ovens disposed side-by-side in a row, comprising a carriage movable along the row of ovens, a quench car movable along a path of travel parallel to and on the side of the carriage opposite that of the row of ovens and on a level below that of the carriage, tubular guide means on the carriage and alignable selectively with each oven for receiving coke from an oven and guiding the coke to the quench car, conveyor belt means in the bottom wall of said tubular guide means for moving coke through the guide means, a hood above the quench car and having a side wall on opposite sides and a top wall above the quench car, track means on opposite sides of the quench car on which the hood is rollably mounted parallel to the path of travel of the quench car, the side wall facing the ovens having an opening communicative with the tubular guide means, means within the hood for spraying water onto the coke in the quench car, and flue means on the top wall for venting non-polluting air from the interior of the hood.
Claim 2
Dependent Claim
