Title: Rotary heat exchanger
Inventor: MORII TAKAYUKI
IPC: B01J19/00
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce energy loss by opening and closing the valve means mounted at a fluid discharge path for heat exchange according to the rotating angle of a heat exchanger. SOLUTION: Valve means 12 and 13 to be opened and closed according to the rotating angle of a heat exchanger 1 are mounted between jacket parts 8 of communicating pipes 9 and 10 connected to the top and bottom of the jacket parts 8 and a passage 11. While the heat exchanger is kept rotated vertically around a rotary joint part 2, steam is supplied to the jacket parts 8. At this time, the steam deprived of the heat condenses to drain which accumulates in the bottom. On the other hand, the valve means 13 is held open in a range of ±45 deg. around the lower perpendicular and, therefore, the drains in the jacket parts 8 may be discharged outside in the range of the angle position. In such a case, the valve means 12 is held closed.  When the heat exchanger 1 rotates further and the angle of the valve means 13 exceeds 45 deg., the valve means 13 is closed, by which the discharge of the drain is stopped and the discharge of the steam in the jacket parts 8 is prevented.
