[Function] The present invention is characterized by adopting a shape formed by a combination of hyperbolic parabolic surfaces instead of the conventionally known truncated cone shape. The hyperbolic parabolic surface is created by the method described below.

The present invention utilizes, as a fluid contact plate, a plate material as shown in FIG. 4 or FIG. As seen in the photographs in Figures 6 and 7, each part is formed from a curved surface and there are no flat parts as conventionally known, so there is no weak point that would cause problems in terms of strength, and the fluid flows along the fluid contact surface. The cross-sectional area of the fluid is always constant and there is no accumulation on the flow path, so the flow is extremely smooth. Furthermore, the fluid can easily swirl along the contact surface.

This makes it a highly economical fluid contact device.
