Abstract

The invention provides a micro-nano bubble gas-liquid reactor. The invention belongs to the technical field of gas-liquid mass transfer. The reactor comprises a reactor shell, wherein a nano-bubble generation area, a gas-liquid mixing cavity, a micron-bubble generation area and a millimeter-bubble generation area are sequentially arranged in the reactor shell; the nano-bubble generation area is adopted to generate nano-bubbles and carry out mass transfer in the gas-liquid mixing cavity; gas is sucked into the nano-bubble generation area, bubbles are broken into nano-bubbles through negative pressure cavitation effect, the nano-bubbles are introduced into the gas-liquid mixing cavity for mass transfer for a certain time, the nano-bubbles sequentially pass through the micron-bubble generatiion area and the millimeter-bubble generation area, the diameters of the bubbles are gradually increased, and the bubbles can reach the size capable of being separated by a cyclone separator. A Venturitype nanobubble generator based on the cavitation effect is used for generating nanobubbles with the extremely large specific surface area, the gas-liquid contact area is increased, the mass transferefficiency is greatly improved, the structure is simple, the cost is low, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of gas-liquid mass transfer, in particular to a multi-stage micro-nano bubble gas-liquid reactor suitable for gas-liquid mass transfer. Background technique [0002] In chemical production and other fields, gas-liquid mass transfer is a very common technical means. The purpose of gas-liquid mass transfer is to absorb gas in liquid or desorb gas in liquid. From the perspective of mass transfer, the most direct way to increase the rate of gas-liquid reaction is to increase the total contact area of ​​gas-liquid. Therefore, the common gas-liquid reactor is formed by atomizing the liquid, forming a film or letting the gas enter the liquid phase. Bubbles are used to increase the gas-liquid contact area. There are mainly the following types of gas-liquid reactors: packed towers, plate towers, bubbling beds, tubular reactors, spray towers, stirred beds, jet reactors, among which packed towers, The internal compon...
