Resin separation tower (SPT)

key word:Heat exchange element


Product description

Resin separation tower (SPT)

 

1. Introduction

1.1 purpose

Resin separation column is used in condensate polishing in vitro regeneration system, which is the most important equipment of "finesep" high column separation technology. The anion and cation resins that failed in the condensate polishing mixed bed are transported to the resin separation tower, and the anion and cation resins are completely separated by air scrubbing and hydraulic screening.

1.2 model significance

1.2.1. The water inlet device is in the form of mother branch pipe, and the branch pipe is covered with trapezoidal wire winding.

1.2.2. The water outlet device is a porous plate with a double speed water cap.

1.2.3. The equipment is lined with 1751 semi-rigid rubber.

1.2.4. The equipment is an inverted conical structure with smaller diameter at the lower part.
