The invention discloses a kind of zero gas consumption compressed air drier by afterheat regeneration, which includes compressed air inlet, ultraviolet catalyzed oil expeller, adsorption tower, thermoelectric converter, storage battery, heating controller, electric heater, external power supply, cooler A, gas-liquid separator A, cooler B, gas-liquid separator B, bag filter, drying compressed air outlet and 5 sets of shut-off valves.The system is different from existing compression heat regeneration absorption drier, its creative design, which has achieved, only needs 1 adsorption tower just can complete the dehydration and drying of compressed air and the regeneration overall process of adsorbent for needing 2 adsorption towers to complete originally, has good drying process effect.The system also creativeness employs thermoelectric generation technology and ultraviolet catalytic decomposition technique, and unnecessary heat can be converted to electric energy, greatly reduce system energy consumption by thermoelectric generation technology；And ultraviolet catalytic decomposition technique can efficiently remove mineral oil contained in air. |
