Regenerative desiccant air dryer

摘要

A gas drying canister housing (200) for a desiccant canister in a gas dryer system includes a main portion (210) having an upper base (202) and a lower portion (220) having a lower base (222). A canister bore (215) is defined between the upper and lower bases when the main and lower portions are fastened to each other. The main portion (210) defines a supply port (230) through which a stream of moisture-bearing gas is directed into the housing (200) for passage through the desiccant canister during a drying mode of operation of the gas dryer system. The main portion (210) also defines a delivery port (240) through which a stream of dried gas is directed from the housing during the drying mode. The lower portion (220) defines a purge port (250) through the lower base (227) through which a stream of remoisturized gas is expelled from the housing (200) during a purge mode of operation of the gas dryer system. The upper base (202) of the main portion features a sealing flange (201) against which an outer rim portion of a top of the desiccant canister is seatable so as to make an air tight seal therebetween. The gas drying canister housing (200) further includes a mechanism for aligning and securably retaining the desiccant canister within the housing.
