HEAT EXCHANGER (DESORBER-ABSORBER) Russian patent published in 2012 - IPC B01D53/18 C02F1/20 

FIELD: process engineering.

SUBSTANCE: heat exchanger relates to desorption of gases from fluids with the help and other inert gas and abruption of definite gases by fluid from gas flow in mutual contact. Proposed heat exchange comprises horizontal casing 1 with bottoms 1a and 1b, fluid feed and discharge branch pipes 2 and 3, respectively. Gas distribution manifold 6 is arranged coaxially inside said casing and provided with branch pipe 7 to feed desorbing or absorbing gas provided with bubbling orifices 8 and inclined baffles 0 arranged above said orifices. Casing bottom 1b has fluid discharge hole 1c arranged on the side of fluid feed branch pipe to define minimum fluid working level. Hydraulic gate 4 is arranged behind said branch pipe and has adjusted height sill 4b to adjust fluid level in aforesaid case while branch pipe 3 to discharge processed fluid us connected to hydraulic gate. Flute 10 to collect and discharge fluid is arranged above aforesaid gas distribution manifold 6.

EFFECT: higher quality of desorption, simplified design, reduced metal consumption.
