Supergravity heterogeneous catalytic reactor device and application thereof

Abstract

The invention discloses a supergravity heterogeneous catalytic reactor device and application. The supergravity heterogeneous catalytic reactor device comprises a motor, a rotating shaft, a shell, a gas-liquid inlet, a gas-liquid outlet, a static flow guide part, a microbubble generation module and a heterogeneous catalytic reaction module, the rotating shaft serves as an output shaft of the motor and extends into the shell from the center of the top end of the shell. Microbubble generation modules and heterogeneous catalytic reaction modules are alternately arranged in the shell from bottom to top; the middle part of the microbubble generation module is fixed on the rotating shaft, and a gap is formed between the outer edge of the microbubble generation module and the shell; the heterogeneous catalytic reaction module is fixed on the inner wall of the shell, and a gap is formed between the center of the heterogeneous catalytic reaction module and the rotating shaft penetrating through the heterogeneous catalytic reaction module; and the static flow guide part is arranged between the shell and the microbubble generation module and is fixed on the shell. According to the device, the characteristic size of the bubbles can be effectively regulated and controlled by adjusting the rotating speed of the supergravity device, the generation of the microbubbles and the catalytic reaction are synchronously carried out in the same reactor, and the investment of equipment is reduced.

Description

technical field [0001] The invention belongs to the supergravity reactor and its application field, in particular to a supergravity multiphase catalytic reactor device and its application. Background technique [0002] For the heterogeneous catalytic reaction process involving insoluble gases such as hydrogen and oxygen in petrochemical, fine chemical, coal chemical, biochemical and other fields, there is often a problem of poor gas-liquid mass transfer, resulting in the macroscopic reaction rate being affected by the gas-liquid mass transfer rate. limit. In industry, the method of increasing the reaction pressure and increasing the amount of hydrogen is generally used to strengthen the gas-liquid mass transfer process. On the one hand, the reaction time is long, which easily leads to the increase of side reaction products, and on the other hand, the amount of hydrogen circulation is large, and the intrinsic safety is low. [0003] With the development of micro-interface s...

Chinese patent 201910163989.0 discloses a high-gravity nano-microbubble generating device and reaction system. At present, the coalescence process of microbubbles and their flow state in the catalyst bed are not clear. The problem of poor gas-liquid mass transfer process caused by coalescence, so it is of great practical application value to develop an integrated reactor with simple equipment structure, rapid and controllable preparation and reaction of microbubbles in large quantities
