    摘要: Vapor and liquid flow concurrently through a vertical vessel. A horizontal flow obstructing mixing device is located within the vessel and forces the vapor and liquid to pass in a vertical direction through one or more inlet openings to the mixing device. The mixing device consists of circular top and bottom walls and a cylindrical side wall. Inside the mixing device curved flow baffles are provided. These flow baffles form one or more tangential inlet orifices, which are located as far from the vessel centerline as possible. The entire process stream flows through the one or more tangential inlet orifices at high flow velocity and in a tangential direction into a swirl box. The high momentum of the process stream in the tangential inlet orifices, the pure tangential direction of the stream, and the large distance between the tangential inlet orifice(s) and the vessel centerline result in a violet swirling flow and in a large number of fluid rotations in the swirl box. The large number of fluid rotations in the swirl box is essential to properly mix the stream(s) entering through the tangential inlet orifice(s) with each other. The fluids exit the mixing device in a vertical direction through an outlet opening in the bottom wall of the mixing device. An impingement plate is located below this outlet opening to spread the liquid and to break down the velocity of the jet. The temperature and chemical composition of the outlet stream is equilibrated.

    摘要: Disclosed is a hydrogen generator that prevents the reformate water from bypassing the evaporator in a hydrogen generator, and the occurrence of sudden temperature changes within an evaporation flow path. The hydrogen generator comprises: an evaporator that produces a mixed gas by mixing a raw material gas containing methane with water vapor; a reformer that changes the mixed gas into a hydrogen-containing gas through a steam reforming reaction; and a combustor that supplies heat to the evaporator and the reformer. The evaporator comprises: an inner cylinder; an outer cylinder enclosing the inner cylinder; and a middle cylinder that is inserted between the inner cylinder and the outer cylinder, and that defines a helical flow path between the inner cylinder and the outer cylinder, through which water supplied from the outside flows. On the inner peripheral surface and the outer peripheral surface of the middle cylinder, helical projections and recesses are integrally formed at the front and back, the top surface of the projections on the inner peripheral surface of the middle cylinder come into contact with the outer peripheral surface of the inner cylinder, and the top surface of the projections on the outer peripheral surface of the middle cylinder come into contact with the inner peripheral surface of the outer cylinder.
