A heat exchange has a main body and a drive shaft in the main body. There is a motor to drive the drive shaft. A rotor is mounted on the drive shaft and has a central hub. Pairs of spaced blades extend radially from the hub to an outer chamber, attached to the outer ends of the blades. There are openings in the hub to communicate a blade with the hub interior and openings in the outer chamber communicating the outer chamber with a blade. There are closure plates at each end of the main body having pairs of inlet/outlet openings. A valve plate between the rotor and each end plate defines gas pathways between on opening and a first end plate and another opening in the second end plate. There are two gas pathways through the apparatus. In the first pathway gas enters an inlet in the first end plate, passes through a valve plate, over the blades of the rotor, through a second valve plate to an outlet of the second end plate. In the other pathway gas enters an inlet in the second end plate, passes through the second valve plate, into the blades, into the chamber, downwardly through the second set of blades, through a second valve plate and out through an outlet in the end plate. |
