FIELD: separation.
SUBSTANCE: invention relates to a liquid collector-mixer for collecting and mixing the liquid, descending from the overlying zone in a mass transfer or heat exchange column. Collector 1 for mixing the liquid contains first and second zones 10, 20 collections, first 40 and optionally the second collection area of the liquid, first and second alternating sets 60, 70 separated by a gap of channels 80 for collecting fluid located in first region 40 of the collection of fluid, wherein first set 60 is associated with said first zone 10 of collections, said second set 70 is associated with said second zone 20 collections, while adjacent channels 80 for collecting fluid from first and second sets 60, 70 are vertically offset from each other in one of at least two to four parallel horizontal planes.
EFFECT: invention provides a plate having combined functions of collecting and mixing liquid, which is less expensive and requires less welding for production, for use in use cases having large loads.
