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

FIELD: process engineering.

SUBSTANCE: invention relates to dust separation equipment. Claimed chamber with gas duct features primarily rectangular cross-section. Note here that duct length-to-height ratio equals 20. One of duct lengthwise walls can displace radially. Gas duct outlet is communicated with moisture trap. Rib is arranged at central part of said chamber along its lengthwise axis, preferably, parallel therewith, to divide it into two equal intercommunicated 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. Gaps are arranged between said rib and bottom in compliance with one version. Note here that every gap makes δ = (0.1…0.3)h, where δ is gap between upper/lower bottoms and rib, h is duct height between said upper and lower bottoms. Rib has through channels to communicate aforesaid cavities of the chamber. Note here total area of channels makes s = (0.25…0.4)S, where s is total area of through channels, S is area of the channel cross-section area at rib location. Rib dividing the chamber cavity into two parts is shaped and has cross-section composed of alternating ledges and recesses. Duct inlet wall is movable. Cold wall is composed of hollow body with working fluid feed and discharge unions. Hot wall is composed by hollow body with working fluid feed and discharge unions. Hot wall is made up of the plate with electric heater arranged at its surface.

EFFECT: complete separation of condensate and impurities from gas flow.
