DIFFERENT-TEMPERATURE CONDENSATION CHAMBER Russian patent published in 2015 - IPC B01D47/05 

FIELD: process engineering.

SUBSTANCE: invention relates to dust precipitation equipment. Different-pressure condensation chamber with rectangular-section gas channel comprises lower bottom, upper bottom, cold and hot channel walls with means providing for temperature difference at outer surfaces of said walls. Duct side walls are composed of parts, flexible jointed, to perform angular and radial displacement both inside and outside of said gas duct. Duct cross-section is defined by the position of moving parts. Rib is fitted at the chamber centre to divide it into two parts. Note also that said rib is fitted along chamber lengthwise axis, mainly, parallel therewith and with shift to stage hot sidewall for x = (0.1…0.3)X, where X is rib shift to hot sidewall, X is channel width.

EFFECT: more complete removal of condensate and mechanical impurities.
