Abstract

A micro-fluidic chip used for analyzing the gathering effect of microbubbles. The invention belongs to the field of microbubble preparation and analysis of interaction of gas and liquid phase fluids in the microchannels, and aims to solve the problem that actual phenomena cannot be accurately represented in the prior art. The micro-fluidic chip includes a cover slice and a substrate slice of whichthe surfaces are attached to and bonded to each other; two parallel liquid channels, a gas channel connected between the liquid channels, and microbubble gathering cavities communicated with one endsof the liquid channels are arranged on the attached surfaces of the cover slice and the substrate slice, wherein the connection position of the liquid channels and the microbubble gathering cavitiesare the microbubble outlets. The other ends of the liquid channels are communicated with each other. A liquid inlet is vertically arranged on the liquid channels and penetrates through the cover slice. A gas inlet is vertically arranged on the gas channel and penetrates through the cover slice. A gas-liquid mixture outlet is vertically arranged on one side, opposite to the microbubble gathering cavities and the microbubble outlets and penetrates through the cover slice.

Description

technical field [0001] The invention belongs to the field of micro-bubble preparation and interaction analysis of gas-liquid two-phase fluid in a microchannel, and in particular relates to a microfluidic chip for analyzing the coalescence effect of micro-bubbles. Background technique [0002] As the country pays more and more attention to sewage treatment, it is essential to establish a complete and efficient sewage treatment system. In the field of sewage treatment, ozone has a very broad application prospect due to its strong oxidizing properties, strong decomposition of organic matter, sterilization, disinfection, and decolorization. However, the ozone treatment sewage technology has not yet been widely promoted, the main reason being the low utilization rate of ozone. It is particularly urgent to research and promote a high-efficiency, high-tech value-added water treatment technology that can meet the needs of practical applications, and the combination of ozone and mic...
