Device for absorption of gas or vapour in a liquid and method for reintroducing vapour or gas in the liquid from which the gas or vapour orginates

摘要

Device for absorption of at least one component chosen among gas and vapor in a liquid based on an ejector principle, comprising a mixing zone in the form of a substantially straight tube (5) immediately downstream of the ejector (1). The device comprises an ejector (1) with central liquid passage (2) and a substantially annular, sectioned aperture (4) for gas/vapor. The gas aperture (4) generally surrounds the central liquid passage (2) and the annular, sectioned aperture (4) for gas/vapor is designed in a manner to cause the gas/vapor to enter the mixing zone with a velocity component that is inclined to the periphery surface of the tube to thereby provide a helical flow (6) downstream of the ejector (1).
