COMPRESSED GAS PURIFYING AND DRYING APPARATUS

摘要

Mechanism for cleaning and drying compressed gas (10) includes a housing (12) having an open end closed by an end cover (14). A desiccant canister (16) is mounted on a plate (24) which is clamped between the end cover (14) and the housing (12) so that the canister (16) is received within the housing (12). A circuitous passage (78) communicates an inlet port (76) with a sump cavity (68) which is communicated with the canister (16). Heat is transferred from the gas to the walls of the passage (78) as the gas passes therethrough. The passage (78) cants toward the sump (68) so that moisture tends to drain into the latter. A dump valve (110) periodically communicates the sump cavity (68) with atmosphere to thereby regenerate the desiccant in the canister (16) and to void the contaminants from the sump cavity (68).
