The invention discloses a liquid distributor of a packed column. An annular plate is fixed on the inner wall of the column body of the packed column; a cylindrical distributing groove allowing liquid to flow down from the annular plate and receiving the liquid is distantly installed below a middle pore passage of the annular plate; a liquid redistributing pore plate with liquid pores is arranged at the groove bottom of the distributing groove; a shallow small ring is connected with the edge of the middle pore passage of the annular plate; the diameter of the inner ring of the cylindrical distributing groove is larger than that of the inner ring of the shallow small ring; and the cylindrical distributing groove is fixed on the inner wall of the column body of the packed column through at least three vertically arranged guiding rib plates which are connected with the outer circumferential wall. The liquid distributor of the packed column has the characteristics of reasonable structure, reliability in use, good using effect and the like.
Description
technical field [0001] The invention relates to a liquid distributor mainly used in a packed tower of a small and medium-sized air separation unit, and belongs to the technical field of liquid distribution in a packed tower. Background technique [0002] In the field of air separation rectification, in order to save manufacturing costs and save energy and reduce consumption during the operation of the air separation unit, the improvement of rectification efficiency plays a pivotal role, and whether the liquid distributor is set reasonably has a great impact on rectification efficiency Big. At present, there are many kinds of distributors used in air separation plants, but there are not many distributors suitable for small and medium-sized air separation plants, and the structure is not reasonable enough, and the use effect is poor. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a liquid ...
