Dispersing Device For Three Phase Fluidized Bed Reactor
Patent Number: JP61287439
PURPOSE: To improve dispersing performance and reactivity of a fluidized bed reactor by installing a dispersing cylinder for passing gas/liquid mixed phase stream penetratedly through an attaching plate of a main body, providing also a valve seat to the top of the dispersing cylinder and a flexible valve body on the valve seat.
CONSTITUTION: A valve body 13 on a valve seat 12 is pushed up by the pressure of gas/liquid mixed phase stream passing through a dispersing cylinder 11 to generate a space between the valve seat 12. The gas/liquid mixed phase stream becomes ejecting stream in the space and is ejected in the horizontal direction from the whole periphery of the space atomizing the gas; thus contact surface area of the liquid with the gas is increased remarkably, and efficiency for feeding the gas/liquid mixed phase to the fluidized bed and reaction efficiency of the gas/liquid mixed phase in the fluidized bed are improved remarkably. Furthermore, when the flow of the gas/liquid mixed phase stream is shielded, the space is eliminated at the same time to establish complete sealing of the system. Accordingly, intrusion of solid into the gas/liquid system is inhibited completely. Therefore, the consumption of gas is saved and performance and reliability of operation are improved remarkably.
