Miniature venturi bubble generation device capable of being modularly assembled

Abstract

The invention discloses a miniature venturi bubble generation device capable of being modularly assembled. The device comprises a miniature venturi bubble generation bottom module, N middle modules and a top module, wherein each middle module comprises a shunt baseboard and an upper cover board; the shunt baseboards comprise module liquid discharging holes, liquid current-sharing channels, miniature venturi channels, laryngeal air inlet grooves, module effluent channels, air-liquid mixture effluent holes and laryngeal air outlets, and the upper cover boards comprise module liquid inlets, laryngeal air inlets and air-liquid mixture outlets. According to the device, a current-sharing channel structure is adopted, thus an even shunt process in a system is achieved, even distribution of flow of all the venturi channels in each module is guaranteed, and the size of broken bubbles is relatively even; the modular assembly mode facilitates disassembly and assembly, and the modules can be increased or decreased according to the preparation amount of the bubbles; by means of modular assembly, the compactness of the device can be greatly improved, the production cost is reduced, and installation space is saved.

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...
