Abstract

The invention provides an underflow distributing device used in serum swirl station, comprising a feed pipe (1), a serum distributing box (2), discharge ports (3) and a switching mechanism (4) provided with a push rod and a pair of parallel tracks, wherein the switching mechanism (4) is positioned above the serum distributing box (2); the parallel tracks are also arranged above the serum distributing box (2); both ends of the push rod are arranged on the tracks; the feed pipe (1) is fixed on the push rod, while the push rod is connected with a drive mechanism; the inlet part of the feed pipe (1) is connected with the underflow pipe positioned at the serum outlet of a swirl station, while the outlet part is communicated with the serum distributing box (2); the bottom of the serum distributing box (2) is provided with two discharge ports (3), while the outlet part of the feed pipe (1) is opposite to the discharge ports (3); in addition, the line of centers of both discharge ports (3) is parallel to the parallel tracks. The invention can guarantee smooth switching of serum without blockage and overflow.

Description

technical field [0001] The present invention relates to an underflow distribution device for a slurry cyclone station. Background technique [0002] Limestone gypsum wet flue gas desulfurization process is a kind of desulfurization technology widely used in our country. [0003] In a typical limestone-gypsum stone wet flue gas desulfurization process, the gypsum slurry generated in the absorption tower after removing sulfur dioxide is pumped into the gypsum slurry cyclone station for concentration through the gypsum slurry discharge pump, and the concentrated gypsum slurry (gypsum cyclone station bottom flow) All go into the gypsum vacuum belt dehydrator for dehydration. After dehydration, the gypsum with a surface moisture content of less than 10% enters the gypsum storage system for shipment. [0004] When the gypsum dehydration system is equipped with 2 gypsum slurry cyclone stations and 2 vacuum belt dehydrators, if one of the belt dehydrators is out of service, and th...
