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. Upper and lower bottoms are connected by side walls to make closed chamber. Said walls are furnished with connectors to allow feeding working body into pipelines and mounting meters therein. Duct side walls are composed of parts, flexible jointed, to perform angular and radial displacement both inside and outside of said gas duct. Note here that said duct is composed of top, bottom and lateral walls. 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: higher gas purity.
