Combined liquid collector and mixer for mass transfer column

摘要

The present invention relates to collector 26, which is used to collect and mix the liquid coming from the upper region in the column for the passed to process fluid flow material, such as to obtain a fractionated product, the collector 26 is liquid the more than one equipped with a collecting area (38,40,42) with more than one drain tank (28,30,32) located around the outer periphery of these areas to a plurality of channels and the deflector each region (38,40, 42) and they are spaced apart in the, steam passage is protected from the vapor passage is lowered to the liquid formed in the space between adjacent channels, while inducing deflector falling liquid to the channel, and each zone (38,40,42 channels are arranged in a set of dugoseo the spacing position, the first set of channels will lead to the collected liquid to the first twos first drain, and inducing a second set of the collected liquid to a first twos second drainage in) . Preferably, approximately equal amounts of liquid in each liquid collection region are, is in a dose and a liquid composition which is more uniform drainage tank be transmitted twos two drainage. At least one drainage tank (28,30,32) is provided with an inlet (34,36) of the down keomeo inducing drainage of the liquid tank (28,30,32) in the lower region, in the collector (26) by mixing a liquid, it can be prevented to use a separate mixer, thus enabling the mixer is usually occupied by a vertical space in the column can be filled with a packing or other internal device so as to increase the efficiency of the column.
