OVERFLOW DEVICE FOR CONTACT PLATE, CONTACT PLATE , AND HEAT AND MASS EXCHANGER Russian patent published in 2004 - IPC

FIELD: separation.

SUBSTANCE: overflow device has housing and reflecting disk mounted in its bottom part so that between the housing and disk is a gap. Inside the housing is a vertical pipe for flowing bypass gas, which is secured to the disk. The pipe is in communication with the space under the plate through the corresponding openings in the disk and has additional openings for inflow of the liquid at the level of the gap between the housing and disk. The pipe is provided with a valve made of a sleeve with holes in the side for gas discharge. The valve is mounted for movement along the axis of the pipe. The holes can be different in shape. If they are tangential slots, the gas flow at the pipe outlet rotates, which contributes to the intensification of the heat exchange. The contact plate consists of the base provided with the overflow device having housing and reflecting disk. The base of the plate can be divided into sections by baffles for additional intensification of the mass exchange. The heat and mass exchanger has housing and vertically arranged contact plate.

EFFECT: enhanced efficiency of heat and mass exchange.
