Compressed gas drying system

摘要

A system for compressing and drying a gas generally includes a compressor having multiple stages of compression and a dryer. The compressor includes a first heat exchanger and an after-cooler each of which utilizes a fan. A sensor is provided downstream of the after-cooler. The fan and sensor are in communication with the controller. A final stage compressed gas outlet of the compressor provides hot compressed gas to the regenerative portion of the dryer. Utilization of the final stage compressed gas for regeneration while also utilizing the compressor's after-cooler provides gas which is sufficiently hot to regenerate desiccant in the dryer and allows the communication between the sensor, the controller and compressors to remain intact.

1. A compressor provided in combination with a regenerative dryer, the combination comprising:
a compressor, the compressor further comprising; a source gas inlet; a first stage compressor in communication with said source gas inlet; a final stage compressed gas outlet; a final stage compressor in communication with said final stage compressed gas outlet and said first stage compressor; an after-cooler; a hot gas inlet in communication with said after-cooler; a cooled gas outlet in communication with said after-cooler; and a dryer, the dryer further comprising; a first desiccant tower; a second desiccant tower; a final stage compressed gas inlet in communication with said first desiccant tower and said final stage compressed gas outlet of the compressor; a hot gas outlet in communication with said first desiccant tower and said hot gas inlet of the compressor; a cool air inlet in communication with said second desiccant tower and said cooled gas outlet of the compressor; a dry air outlet in communication with said second desiccant tower; and a plurality of lines and valves for directing the gas flow through the dryer.
