Title:
CENTRIFUGAL SEPARATOR
Document Type and Number:
Japanese Patent JPH05123610
Kind Code:
A
Abstract:

PURPOSE: To simplify the structure, to make insulation layers hardly damaged and to avoid occupying a large area by forming the cross-section delineated by the side part walls of a vortex chamber in a square shape, setting the length of the longer side part walls at a specific ratio to the short side part walls and providing the vortex chamber with ≥2 continuous gas outlets in its longitudinal direction.

CONSTITUTION: The centrifugal separator 12 consists of cooling planar plates or panels and has a gas inlet 30, outlets 54, 56 and an outlet for separated particles. The cross section of the side walls 34, 38 of the vortex chamber form a non-circular gas space and has a circularity of greater than 1, e.g. ≥1.1 and preferably ≥1.15. One or more vertical, parallel gas vortices may be created in the vortex chamber and the gas is introduced into vertical narrow slots. The outlets for separated particles are not on the same symmetrical axes as the outlets for purified gas. Two adjacent vortices may be provided in a common rectangular chamber. The separator is preferably in conjunction with a circulating fluidized bed reactor.
