Abstract

The invention discloses the technical field of petrochemical engineering, and relates to a micro-bubble generation device, and a micro-bubble generation control method and device. Liquid materials pass through a contraction section, then enter a gas distribution perforated pipe on an gas inlet section, gas and liquid are mixed in the gas distribution perforated pipe, and then a mixture enters an expansion section and a gas-liquid expansion section. According to the micro-bubble generating device, a Venturi tube and micropore distribution principle is utilized, micro-bubbles with high dispersion are formed, fluid effectively shears and crushes the bubbles, and large bubbles are crushed under the action of pressure recovery in the micro-bubble generating device to form the micro-bubbles; and an internal component or a rotational flow device is not adopted, fluid energy dissipation is effectively reduced, coalescence of tiny bubbles is also avoided, and the micro-bubble fraction is remarkably increased.

Description

technical field

[0001] The invention relates to the technical field of petrochemical industry, and in particular to a microbubble generating device, a method and a device for controlling microbubble generation. Background technique

[0002] In the chemical, biological and environmental fields, gas-liquid phase reactions exist widely, and mass transfer through bubble dispersion has been widely used. For gas-liquid reaction processes controlled by mass transfer rate such as hydrogenation and oxidation, the use of microbubbles to enhance mass transfer has important practical value. For the gas-liquid mass transfer process, microbubbles have a huge gas-liquid contact area per unit volume to enhance mass transfer, and microbubbles have a small volume, which makes them less lift. Therefore, microbubbles can improve the contact efficiency of gas-liquid devices, and can be applied in equipment such as bubble columns, reactors, gas absorption and fermentation tanks. The premise of ...
