A Modularly Combinable Miniature Venturi Type Bubble Generating Device

Abstract

The invention discloses a modularized combinable miniature Venturi type air bubble generating device. The device includes a bottom module for generating micro Venturi type bubbles, N middle modules and a top module, and each middle module includes a flow-distributing bottom plate and an upper cover plate. Among them, the distribution bottom plate includes the module liquid outlet hole, the liquid flow channel, the micro Venturi channel, the throat inlet slot, the module outlet channel, the gas-liquid mixture outlet hole, and the throat outlet hole. The upper cover contains the module liquid Inlet, throat air intake, outlet of gas-liquid mixture. The present invention adopts the structure of the equalizing channel, which realizes the uniform shunting process inside the system, ensures the uniform distribution of the flow rate of each Venturi channel in a single module, and makes the size of the broken bubbles more uniform; the way of modular combination is convenient for disassembly and installation , can increase or decrease modules according to the amount of bubble preparation; modular combination can greatly improve the compactness of the device, reduce manufacturing costs, and save installation space.

Description

technical field [0001] The invention relates to a generating device suitable for preparing a large number of tiny air bubbles. Background technique [0002] Microbubbles have the characteristics of large specific surface area, slow rising speed, excellent solubility, strong surface adsorption, and long-term residence in water, which can greatly enhance the heat and mass transfer process, so they are widely used in many fields, such as Mineral flotation, sewage treatment, aquaculture, soilless cultivation, ship drag reduction, scrubber, molten salt stack degassing system, etc. [0003] Due to its simple structural design, safety and reliability, low energy consumption and excellent bubble generation performance, the Venturi channel is often used as a bubble generation device. [0004] In the practical application of the above fields, a large number of micro-bubbles with uniform size are often required, which requires the ability of the micro-bubble generator to generate micr...

Problems solved by technology

[0004] In the practical application of the above fields, a large number of micro-bubbles with uniform size are often required, which puts forward requirements on the ability of the micro-bubble generator to generate micro-bubbles, and the ability of a single Venturi-structured bubble generator to prepare bubbles is very limited.
