PERFECTED CONTACT STAGES FOR DEVICES WITH COCURRENT CONTACT Russian patent published in 2013 - IPC B01D3/16 B01D3/22 B01F3/04 

FIELD: process engineering.

SUBSTANCE: invention relates to perfected contact stages for bringing steam in contact with fluid. Invention relates to contact stage 12 for bringing steam in contact with fluid that comprises: pair of rows 24 of entrainment traps spaced apart and including multiple separate entrainment traps 40, joint flanges 74 extending above top surfaces 45 of the latter. Also it comprises pair of accumulation pans 26 arranged at alternating said rows 24, drain barrel 22 arranged between said rows 24 to make along with inlet surfaces 42 of entrainment traps 40 and pair of channels 56 for cocurrent flows on opposite side of barrel 22. Also it comprises connection angle-pieces 75 extending above top parts of said angles 74 of entrainment traps 40. Note here that connection angles 75 cover joint flanges 74 and adjacent sections 72 of drain barrel 22 to attach top parts of entrainment traps 40 to drain barrel wall 22. Note also that lower parts 97 of entrainment traps 40 are secured to pans 26. Invention covers also device and method for cocurrent contact between steam and fluid.

EFFECT: simplified assembly, notable increase in stiffness, higher efficiency, lower probability of fluid leaks.
