Regenerative heat exchanger

摘要

A regenerative heat exchanger for gaseous media which are in a heat exchange with one another includes stationary or rotating storage masses and at least one cleaning device for the storage masses, wherein the cleaning device can be pivoted in relation to the annular cross section of the storage masses from the inside toward the outside or vice versa. The regenerative heat exchanger can be used for the preheating of air as well as for the preheating of gas. The free end of a swivel arm of the cleaning device constructed as a blow tube has a bent portion which extends parallel to the plane of the storage masses and the bent portion is provided with at least two blow nozzles.
