Vortex air inlet system, compressor system and related method

摘要

An aeration system (10) which feeds air to multiple water basins (12) and method. A plurality of local processor based control modules (208) is provided. Each module controls the operation of a compressor unit (11) to effect functions including changes in compressor power level, thermal control and blow-off during compressor start-up. The compressor units (11) are assembled in systems and each system is allocated to a different basin so that no two compressors (22) provide air to the same basin (12). A plurality of control operations are performed with a central processor (300) wherein the central processor directly controls aeration valves 324 in each basin 12 based on monitored oxygen levels.

1. An aeration system for a waste water treatment plant having multiple water treatment aeration basins, comprising:
a controller; and a plurality of modular compressor systems each allocated to a different basin in an aeration system, each compressor system including (i) an air inlet system for receiving ambient air and discharging cleaned air and (ii) at least one compressor unit positioned to receive the cleaned air and to output compressed air, the air inlet system designed to be placed on top of the at least one compressor unit, each compressor unit including a compressor and a processor based control unit responsive to commands received from the controller, wherein: the controller is coupled to receive data from (i) a plurality of dissolved oxygen sensors each positioned to receive data from a different one of the basins, (ii) multiple flow meters indicative of air flow into each basin, and the controller is operatively coupled to adjust air flow into each of the basins; each control unit is coupled to respond to the controller to adjust the air flow into a basin and is also operatively linked to other components in the unit to adjust power input to the compressor, blow-off pressure during compressor start-up and valve controls to effect cooling of components in the unit; and each compressor system comprises a series of modular, vertically stackable units with anchoring of one unit to another unit to provide a stable structure in which the air inlet system is positioned above the compressor.
