PARTICLE SAMPLING DEVICE OF FIXED BED

摘要

A particle sampling device for analyzing particle size distribution or fine particle fraction according to depths of respective beds during opening of an adsorption chamber in the Parex process is provided. In a particle sampling device used in a fixed bed catalytic reactor or adsorption tower, a device for sampling particles of fixed beds comprises: a valve(1) formed on an upper portion of the device; a drive part(2) distanced downward from the valve and formed in an "U" character shape; a through hole(3) of a predetermined length formed from a portion distanced downward from the drive part to a lower end of the device; a sample entering-and-exiting hole(7) extending from the through hole; a tapered part(5) radially inclined from an inner peripheral surface of the sample entering-and-exiting hole to an outer peripheral surface of the device; and a screw thread part(6) formed in a screw shape from one end of the tapered part to the upper side.
