Abstract

The invention discloses a gas-liquid mixing device and its application. The gas-liquid mixing device includes a gas-liquid mixing device housing, and the housing contains a number of parallel gas-liquid mixing components; the gas-liquid mixing component is a cavity structure, along the material The flow direction is the preliminary gas-liquid mixing section, the accelerated gas-liquid mixing section and the gas release section in sequence, and each section is connected to each other; the accelerated gas-liquid mixing section is a conical contraction structure, and the initial end of the accelerated gas-liquid mixing section is connected to the high-pressure gas dispersion In the equipment, the middle and rear part of the gas release section is provided with a gas phase outlet for releasing the escaped gas, and the end of the gas release section is provided with a liquid phase outlet. The "gas-in-oil type" gas-liquid mixed fluid formed by the equipment is homogeneous and stable, which can greatly increase the mass transfer area of ​​the liquid, so that the gas-liquid reaction process can maintain a high rate continuously, and solve the large number of liquid cycles existing in the prior art , High material consumption and energy consumption, long residence time and other issues.

Description

technical field [0001] The invention belongs to the field of gas-liquid mass transfer reaction, in particular to a new type of gas-liquid mixing equipment and its application method, which can be widely used in gas-liquid reactions in the fields of petroleum, chemical industry, light industry, medicine, environmental protection, etc. process. Background technique [0002] In the fields of petroleum, chemical industry, light industry, medicine, environmental protection, etc., many gas-liquid-solid three-phase reaction processes in fixed beds are involved. The solid is the catalyst, and the gas-liquid two-phase passes through in the form of trickle flow. Catalyst bed, so also called trickle bed reactor. [0003] In the trickle bed reactor, the gas needs to be transferred from the gas phase to the liquid phase, and then co-adsorbed on the surface of the catalyst to react under the action of the active center of the catalyst. In general, in order to enhance the mass transfer o...
