METHODS AND SYSTEMS FOR IMPROVED QUENCH TOWER DESIGN

摘要

The present technology describes methods and systems for an improved quench tower. Some embodiments improve the quench tower's ability to recover particulate matter, steam, and emissions that escape from the base of the quench tower. Some embodiments improve the draft and draft distribution of the quench tower. Some embodiments include one or more sheds to enlarge the physical or effective perimeter of the quench tower to reduce the amount of particulate matter, emissions, and steam loss during the quenching process. Some embodiments include an improved quench baffle formed of a plurality of single-turn or multi-turn chevrons adapted to prevent particulate matter from escaping the quench tower. Some embodiments include an improved quench baffle spray nozzle used to wet the baffles, suppress dust, and/or clean baffles. Some embodiments include a quench nozzle that can fire in discrete stages during the quenching process.

主权项

1. A system for quenching coke, comprising:
a quench tower formed from a plurality of side walls joined together to create a partially open top portion that defines a quench tower physical perimeter, at least one side of the quench tower containing an opening through which a train car may enter and/or exit; and one or more sheds formed from one or more outwardly extending surfaces joined to a side wall of the quench tower to create a substantially closed top portion that defines a shed physical perimeter, wherein:
a combination of the quench tower physical perimeter and the shed physical perimeter defines a quench tower effective perimeter;the quench tower effective perimeter is larger than the quench tower physical perimeter;the quench tower physical perimeter is larger than or equal to a train car perimeter, the train car perimeter being defined by a plurality of sides joined together to form the train car; andthe quench tower effective perimeter is configured to provide an enhanced draft distribution profile.
