Abstract
A rotor construction for a rotary regenerative heat exchanger in which sector-shaped compartments are formed between imperforate diaphragms that extend radially outward from a central rotor post. The diaphragms serve to form the sector-shaped compartments that are packed with heat absorbent plates, while they simultaneously serve as imperforate barriers which preclude fluid flow laterally between compartments as the rotor is being moved alternately between a heating fluid and a fluid to be heated. In order to simplify construction of the rotor and to improve the operating efficiency thereof, the heat absorbent element plates are arranged in a radial pattern whereby they serve as radial sealing members while they simultaneously serve as heat absorbent element.
Claims5
Rotary regenerative heat exchange apparatus having a rotor post, a plurality of imperforate diaphragms connected to the rotor post and extending radially from the rotor post to provide a framework for a rotor having a series of sectorial compartments therebetween, a rotor shell joining ends of the diaphragms to enclose the rotor, housing means surrounding the rotor having end plates at opposite ends thereof with imperforte sections between spaced openings that direct a heating fluid and a fluid to be heated axially through the compartments of the rotor, means for rotating the rotor about its axis to alternately align the rotor with the heating fluid and with the fluid to be heated, and imperforate heat absorbent plates carried by each compartment of the rotor midway between diaphragms being radially disposed to axially confront the imperforate portions of the end plates in a sealing relation to preclude the flow of fluid laterally between opposite sides of the lateral plates.
