Dry flue gas desulfurization system with dual feed atomizer liquid distributor

摘要

An atomizer system 160 for use in a spray dry absorber 130, the atomizer system 160 includes a support member 161, an atomizing disc 162 rotatably coupled to the support member 161, a first feed line 163 for delivery of a reagent slurry 163a to a delivery area 165 and a second feed line 164 for delivery of a dilution liquid 164a to the delivery area 165. The delivery area 165 is positioned within the atomizer system 160 to reduce scale buildup generated by interaction of the reagent slurry 163a and the dilution liquid 164a.

1. An atomizer system for use in a spray dry absorber, the atomizer system comprising:
a support member; an atomizing disc rotatably coupled to the support member; a first feed line for delivery of a reagent slurry to a delivery area; and a second feed line for delivery of a dilution liquid to the delivery for contact between the reagent slurry and dilution liquid in the delivery area to produce an atomized reagent, the delivery area positioned within the atomizer system in communal proximity upstream the atomizing disc to reduce scale buildup in the delivery area generated by interaction of the reagent slurry and the dilution liquid prior to atomized reagent delivery to and atomization by the atomizing disc rotation; wherein the delivery area comprises a stationary plate positioned upstream the atomizing disc.
