Title:
STEAM COMPRESSOR
Document Type and Number:
Japanese Patent JP2011099395
Kind Code:
A
Abstract:

To provide a steam compressor capable of preventing the atmosphere from flowing into a steam chamber even in case where the pressure of the steam sucked into the chamber is lower than the atmospheric while a drop of the compressed steam producing efficiency is suppressed.

The steam compressor is equipped with a first suction side seal part 10 arranged at a suction side shaft sealing chamber 35 in its position apart toward the steam chamber 32 from the connection part of the passage 38 for suppressing the steam in the chamber 32 flowing to the passage 38, a second suction side seal part 12 arranged at the suction side shaft sealing chamber 35 in its position between the connection part of the suction side atmosphere releasing passage 38 and the first suction side seal part 10 for suppressing the steam flowing to the passage 38, a first discharge side seal part 16 of non-contact type arranged at a discharge side shaft sealing chamber 39 for heightening the flow resistance to the steam leaking from the steam chamber 32 to the discharge side shaft sealing chamber 39, and a communication part 22 to put two regions in communication with each other, i.e. one region between the seal parts 10 and 12 of the suction side shaft sealing chamber 35 and another region between the seal parts 16 and 18 of the discharge side shaft sealing chamber 39.
