Graphite heat exchanger for preparing polyaluminum chloride

Abstract

The utility model discloses a graphite heat exchanger for polyaluminum chloride preparation, it includes jar body, front cover and back cover, the fixed coupling of jar body has graphite pipe plate and two groups of baffle, the graphite pipe plate is located jar body both ends respectively, the symmetry of being equipped with two groups of baffle in jar body inner wall, be equipped with a plurality of heat exchange pipes in the jar body, the mounting hole for heat exchange pipe is passed through and is seted up in the baffle surface, and the both ends fixed connection of baffle have inserted joint and elastic sheet, the elastic sheet is equipped with multiple and equidistance encircles in heat exchange pipe outside, graphite block is fixedly connected to the one end of elastic sheet away from baffle. When the graphite heat exchange pipe is inclined before passing through the baffle, the graphite heat exchange pipe is righted, avoids the collision of graphite heat exchange pipe and baffle, and the elastic sheet makes graphite block closely pass through the surface of graphite heat exchange pipe of baffle, further improves the stability effect to graphite heat exchange pipe.
