Abstract

The invention discloses a gas-liquid reactor, which comprises a vertical tube reactor body, a liquid injection tube and a gas injection tube. The upper part of the vertical tube reactor body is provided with a gas outlet, the bottom part is provided with a liquid outlet, and the middle part of the reactor body is fixed. An annular catalyst layer is set, and the reactor body also includes an annular steel mesh placed above the catalyst layer through a plurality of spring supports, and the liquid injection pipe extends downward from the top of the reactor body through the annular steel mesh and the catalytic layer. The lower part of the reactor body, the gas injection tube passes through the side wall of the lower part of the reactor body and also extends into the lower part of the reactor body, and the outlet end of the liquid injection tube and the outlet end of the gas injection tube are respectively provided with a liquid nozzle with an opening facing downward and an opening facing upward. The gas nozzles are arranged opposite to each other; the invention has a simple structure and a large gas-liquid contact area, which can realize high-speed collision mixing of reactant gas and liquid, strengthen interphase mixing between reactant materials, and enhance heat and mass transfer effects.

Description

technical field [0001] The invention relates to a gas-liquid reactor and a gas-liquid reactor group composed of a plurality of gas-liquid reactors connected in series. Background technique [0002] At present, there are many types of equipment for gas-liquid two-phase mixing, which can be divided into: (1) bubble column reactors in which gas is dispersed in the liquid phase in the form of bubbles, stirred bubble tank reactors according to the gas-liquid phase contact form and plate reactors; (2) spray, spray and Venturi reactors in which the liquid is dispersed in the gas phase in the form of droplets; (3) packed tower reactors and falling film reactors in which the liquid contacts the gas phase in a film-like motion . None of these existing reactors can maximize the gas-liquid contact surface, which affects mass transfer and heat transfer. Contents of the invention [0003] The invention provides a gas-liquid reactor with a simple structure and a large gas-liquid contac...
