Pollution-free coke quenching system

Claim 2

IN A COKE QUENCHING SYSTEM, THE COMBINATION COMPRISING: MEANS DEFINING AT LEAST ONE VEHICLE HAVING A COKE RECEIVING CAVITY, A COKE ADMITTING OPENING COMMUNICATING WITH SAID CAVITY AND A COKE RELEASING EXIT COMMUNICATING WITH SAID CAVITY, AND ADAPTED TO TRAVEL BETWEEN A COKE RECEIVING STATION AND A COKE DUMPING STATION, A HOOD ON SAID VEHICLE MEANS OVER SAID COKE RECEIVING CAVITY AND ADJACENT ONE SIDE OF SAID COKE RECEIVING OPENING, EXHAUST MEANS ON SAID VEHICLE MEANS IN FLUID COMMUNICATION WITH SAID HOOD FOR WITHDRAWING GASES WITHIN SAID COKE RECEIVING CAVITY AND INCLUDING TWO-PHASE JET MEANS FOR INDUCING A DRAFT AND FOR SCRUBBING GASES WITHDRAWN FROM SAID CAVITY TO REMOVE PARTICULATE MATERIAL THERE FROM, DE-MISTING MEANS ON SAID VEHICLE MEANS FOR RECEIVING MATERIAL FROM SAID TWO-PHASE JET MEANS, A PLURALITY OF QUENCH SPRAY JETS ON SAID VEHICLE MEANS, ALL DIRECTED AT THE INTERIOR OF SAID CAVITY, AND MEANS ESTABLISHING FLUID COMMUNICATION BETWEEN SAID DE-MISTING MEANS AND SAID QUENCH SPRAY JETS WHEREBY LIQUID SEPARATED FROM GASES THEREBY MAY BE SUBSEQUENTLY USED FOR THE QUENCHING OF COKE IN SAID CAVITY.

Claim 3

In a coke quenching system, the combination comprising: means defining at least one vehicle having a coke receiving cavity, a coke admitting opening communicating with said cavity and a coke releasing exit communicating with said cavity, and adapted to travel between a coke receiving station and a coke dumping station; a hood on said vehicle means over said coke receiving cavity and adjacent one side of said coke receiving opening; exhaust means on said vehicle means in fluid communication with said hood for withdrawing gases within said coke receiving cavity and including two-phase jet means for inducing a draft and for scrubbing gases withdrawn from said cavity to remove particulate material therefrom; de-misting means on said vehicle means for receiving material from aid two-phase jet means; means on said vehicle means for providing hot water to said two-phase jet means and including a heater; water storage means on said vehicle means for providing water to said heater; means on said vehicle means establishing fluid communication between said de-misting means and said water storage means; a plurality of quench spray jets on said vehicle means, all directed at the interior of said cavity; and means establishing fluid communication between said de-misting means and said quench spray jets whereby liquid separated from gases thereby may be subsequently used for the quenching of coke in said cavity.

Claim 4

In a coke quenching system, the combination comprising: means defining at least one vehicle having a coke receiving cavity, a coke admitting opening communicating with said cavity and a coke releasing exit communicating with said cavity, and adapted to travel between a coke receiving station and a coke dumping station; a hood on said vehicle means over said coke receiving cavity and adjacent one side of said coke receiving opening; exhaust means on said vehicle means in fluid communication with said hood for withdrawing gases within said coke receiving cavity and including two-phase jet means for inducing a draft and for scrubbing gases withdrawn from said cavity to remove particulate material therefrom; de-misting means on said vehicle means for receiving material from aid two-phase jet means; means on said vehicle means for providing hot water to said two-phase jet means and including a heater; water storage means on said vehicle means for providing water to said heater; means on said vehicle means establishing fluid communication between said de-misting means and said water storage means; a plurality of quench spray jets on said vehicle means, all directed at the interior of said cavity; and means establishing fluid communication between said de-misting means and said quench spray jets whereby liquid separated from gases thereby may be subsequently used for the quenching of coke in said cavity.

Claim 5

The coke quench system of claim 2 further including barrier spray means on said vehicle means for generating a fluid barrier across said coke admitting opening to preclude gases from exiting said cavity therethrough; fog spray means on said vehicle for generating a fog within said cavity to protect said hood from heat from coke received in said cavity; and means including a pump for delivering water from said water storage means to said barrier and fog spray means.
