US 2016/0250587 A1 · METHOD AND APPARATUS FOR WET DESULFURIZATION SPRAY TOWERS

Abstract

A method and apparatus or system is provided for cleaning a flue gas and/or cooling a flue gas with a dispersed finely divided absorption liquid. As such, the absorption liquid is dispersed in a wet scrubber through which flue gas flows for absorption liquid and flue gas intermingling and contact to produce a cleaned flue gas. The absorption liquid supplied to the wet scrubber is dispersed from upwardly spraying anti-clogging nozzles and downwardly spraying nozzles arranged to maximize absorption liquid and flue gas contact with minimal spray interference between nozzles.

Dependent claims

A system comprising:

a wet scrubber with at least a first spray level and a second spray level;
downwardly spraying nozzles on each the first spray level and the second spray level arranged in vertical alignment one above the other;
upwardly spraying anti-clogging nozzles alternating between the downwardly spraying nozzles on each the first spray level and the second spray level also arranged in vertical alignment one above the other;
and
each upwardly spraying anti-clogging nozzle comprising an upward extending portion and an opposed extended portion operable for particulate flow from the upward extending portion to the opposed extended portion to prevent particulate clogging of the upward extending portion.
