The height can be reduced. Further, according to the present invention, the height of the element 2 can be reduced and stored in a horizontally long (horizontally placed) container. In addition, since the flow direction of the gas-liquid two-phase flow and the inflow direction of the inlet of the element 2 coincide with each other, and the outlet direction also becomes the outflow direction, drift is prevented.
