Abstract： |
The present invention relates to a kind of convection and pressure loss preventing hot gas conduit, and belongs to the field of nuclear technology. In order to solve the problems of helium convection inside hot gas conduit and abrupt pressure loss of hot gas conduit in accident condition, the present invention discloses one kind of convection and pressure loss preventing hot gas conduit, which includes from inside to outside the sectioned inside pipe, thermal insulation fiber layer and outer airtight cylinder. Between each section of inside pipe and the outer cylinder, there is one section of conic thin-wall pipe with one end welded to outer wall of the inside pipe and the other end to the inner wall of the outer cylinder for firmly connection and positioning. There is expansion gap between every two sections of inside pipe. The present invention can raise the heat efficiency and safety of the reactor. |
