Spray Nozzles Reduce Air Consumption by Over 40 Percent in Lead Smelting Operation
Data Verified by the OEM Manufacturer
PROBLEM: A Pennsylvania wet battery manufacturer used Spraying Systems Co.'s ¼J nozzle assemblies for coating a fiber bed in a candle on a mist eliminator to "wick out" or eliminate ammonium sulfate from the gas stream before being released through the eliminator stack. If the fiber bed doesn't stay wet, the wicking action of the candle is reduced, creating emission problems. The nozzles did a good job of reducing the emissions, however, they consumed a great deal of air which resulted in high utility costs for the smelting operation.
SOLUTION: When Spraying Systems Co. introduced its new KYNAR® QuickMist™ air atomizing nozzles, the sales engineer knew these compact nozzles would be a perfect replacement for the ¼J nozzle assemblies. The QuickMist nozzles provide the same degree of atomization and the same liquid flow rates as conventional air atomizing nozzles, but use up to 50 percent less air. The QuickMist nozzles were designed to easily replace the existing ¼J nozzle assemblies without changing out fittings or nozzle positions.
The battery manufacturer sent the QuickMist nozzles to the OEM manufacturer of the environmental system, to verify the over 40 percent air reduction claim. Independent testing confirmed that the nozzles saved over 153 SCFM or 34 HP. That's a reduction of over 40% compared to the previous nozzles.
The manufacturer now enjoys lower utility bills without compromising emission standards. The QuickMist nozzles have a 3.9 gph (14.8 l/hr) capacity, the required rate per candle. The reduction in air consumption places less demand on the plant's compressor.
Plus, the QuickMist nozzles are constructed of PVDF - a super tough, chemical-resistant fluoropolymer. That means it can stand up to a variety of temperature ranges and resists acids, bases and oxidizing agents.
