Abstract
In a rotary heat exchanger, two groups of tubes are concentrically arranged about a drive shaft and the tubes have ports at their ends which are in communication with inlet and discharge chambers to which respective streams of gas are delivered so that two separate streams of gas may be circulated through the tubes. A solid granular material is supplied into the tubes of one group at one end and, near the other end, the tubes of the first and second groups are interconnected for passing the material from one group to the other.
Claims10
A rotating heat exchanger comprising
- a. an axle of rotation,
- b. a first group of tubes arranged about the axle of rotation,
- c. a second group of tubes arranged about the first group of tubes,
- 1. the tubes of the first and second groups having axes parallel to the axle of rotation and
- 2. each of the tubes having ports at respective ends thereof, the ports of the tubes of the first and second groups of tubes at each of the ends being substantially coplanar,
- d. respective gas inlet and discharge chambers in communication with the ports at respective ends of the heat exchanger,
- e. means for circulating a first stream of gas between the chambers through the tubes of the first group,
- f. means for circulating a second and separate stream of gas between the chambers through the tubes of the second group,
- g. means at one of the ends for supplying a solid granular material into the tubes of one of the groups,
- h. channel means near the other end for connecting the tubes of the first and second groups for passing the solid granular material from the one to the second group of tubes, and
- i. outlet means at the one end for removing the solid granular material from the second group of tubes.
