Gas-Solid Phase Catalytic Reactor

Abstract

The invention discloses a gas solid phase catalytic reactor. The gas solid phase catalytic reactor comprises a shell of which the upper part is provided with an inlet and the lower part is provided with an outlet, catalytic bed assemblies and flower plates provided with passage ports; each catalytic bed assembly comprises an inlet distribution member with small holes, an outlet distribution member with small holes and a seal plate; the seal plate is arranged on the top of the inlet distribution member and the outlet distribution member; the gap between the inlet distribution member and the outlet distribution member is provided with a catalytic bed filled with the catalyst; the other side of the inlet distribution member is a fluid inlet passage which is communicated with an inlet; and the other side of the outlet distribution member is a fluid outlet passage which is communicated with a passage port on each flower plate; and the flower plates are fixed on the lower part in the shell,and the lower end of each inlet distribution member, the lower end of each outlet distribution member and the flower plate are hermetically sealed. The formed bed is extremely low in pressure drop, can effectively save energy and reduce consumption, and can be widely applied to petrochemical industry, inorganic chemistry industry, or organic chemical industry.

Description

technical field [0001] The invention relates to a fixed-bed catalytic reactor used for gas-solid phase catalytic reaction in the field of chemical industry. Background technique [0002] In the chemical industry and petrochemical industry, the fixed bed catalytic reactor is a widely used core equipment. , Hydrofining and other chemical processes, the reactor type has a fixed bed. [0003] Fixed-bed catalytic reactors can be divided into two categories: axial reactors and radial reactors according to the way the fluid passes through the bed. The reactor in which the fluid passes through the catalyst bed in the direction pointed by the central axis of the reactor is called an axial reactor. The reactor in which the fluid passes through the catalytic bed in the direction of radius or diameter is called radial reactor. [0004] The axial reactor has a simple structure and is easy to use, but the fluid channel is limited by the cross-section of the equipment, resulting in a la...

Problems solved by technology

[0024] However, how to further reduce the bed resistance in industry, for example, to the order of 1KPa, obviously, it is difficult to achieve the above reactor types in an economical and reasonable way.
