Title:
DOUBE-PIPE OPEN-RACK VAPORIZER
Document Type and Number:
Japanese Patent JP2754147
Kind Code:
B2
Abstract:
PURPOSE: To evenly divide a fluid flow at a turning point of the fluid.
CONSTITUTION: Liquefied natural gas is caused to flow from the lower end of an internal tube 6 upwardly through an annular passage in an external tube 2, in a U-shaped flow pattern, wherein holes 10, 11 are provided on the outer periphery of the lower end of the tube 6 to reverse the flow of fluid so that the fluid flows out of the side wall of the tube 6 and is caused to flow reversely, and hence differences in the shape of the turning point of the fluid due to errors in the fabrication of a joint at the manufacture thereof are not generated, thereby facilitating the manufacturing thereof. Further the lower end of the tube 6 is closed or it is brought into contact with the closed inner surface 3 of the external tube, whereby the fluid flows out only through the holes so as to be reversed so that the fluid flows evenly, and the lower end of the tube 6 is prevented from being moved by vibration or the like, thereby preventing the dimension of the fluid passage from becoming uneven.
