Low-noise feeding of fluid into liq., gas or fluidised bed - using a multi-jet nozzle composed of plastics base with tubes of different lengths

摘要

Process of introducing fluids into liqs., fluidised beds or gases with the min. of noise comprises splitting the stream of fluid into part currents, conveying these through pipes of different lengths and introducing them into the liq., fluidised bed or gas. Specifically, numerous small pipes of different lengths are mounted upon a common base which is made of plastics, pref. a fluoro plastics, thus forming a multi-jet nozzle.
