Fluidized Bed Solid Circulation System using Two Ways Loop Seal

摘要

The present invention relates to a bidirectional loop chamber and a fluidized bed solid circulation system using the bidirectional loop chamber, and more particularly, between two fluidized bed reactors, some solids are introduced into the first fluidized bed reactor, and the remaining solids are introduced into the second fluidized bed reactor. In the two-way loop chamber for introducing into the solid, solid downcomer into the solid; A first solid riser pipe branching to one side of the solid descending pipe and a second solid riser pipe branching to the other side; A first solid outlet which is bent at the top of the first solid riser so that the solid flows into the second fluidized bed reactor; A second solid outlet bent above the second solid riser so that the solid flows into the first fluidized bed reactor; A gas introduction chamber connected to a lower end of the solid descending pipe to introduce a roof chamber fluidized bed gas; An introduction chamber partition wall provided in the gas introduction chamber and separating the gas introduction chamber into one side and the other side; And a downcomer partition wall connected to the upper side of the introduction chamber partition to separate the solid downcomer into a first solid downcomer on one side and a second solid downer on the other side. .
