| 摘要 |
A rotary heat exchanger comprising a rotor extending along an axis of rotation and having, at opposite axial ends of the rotor, respective first and second axial end surfaces substantially perpendicular to the axis and surrounding the axis, a first sector plate having a sealing surface adjacent the first axial end surface, the sealing surface extending across the first axial end surface so as to divide the first axial end surface into two halves, wherein the first sector plate defines suction ducts extending through the first sector plate from the sealing surface, and the rotary heat exchanger further includes a pressure device arranged to draw gas through the suction ducts from between the sealing surface and the first axial end surface. The pressure device may be a suction device. There may be provided a second sector plate extending across the second axial end surface arranged opposite to the first sector plate. There may be a gas inlet duct and a gas outlet duct provided at each axial end of the rotor. There may be a support frame provided that includes sector plate ribs. |
