Abstract

The invention discloses a generating device for micro-nano air bubbles and a device. The generating device comprises two fixing rods; two fixing trays are fixedly jointed between the two fixing rods;Venturi tubes are fixedly connected with the middle parts of the two fixing trays; water inlets are dug on opposite ends of the two Venturi tubes; stretchable pipes are fixedly jointed in the two Venturi tubes; chokes are fixedly connected with the middle parts of the inner walls of the Venturi tubes. According to the invention, a double flow colliding type vertical structure is adopted; micro-nano air bubbles generated by the two Venturi tubes collide with each other in colliding gaps, so that a strong turbulent flow is generated herein for secondarily breaking the micro-nano air bubbles; thecollided mixture passes by a contraction section; effluent is sprayed from a diffusion port and the air bubbles are broken again, so that more micro-nano air bubbles in smaller grain size can be acquired; convenience in use, high efficiency and wide range of application can be guaranteed.

Description

Technical field: [0001] The invention belongs to the technical field of micro-nano bubbles, in particular to a device and method for generating micro-nano bubbles. Background technique: [0002] Compared with traditional large bubbles, micro-nano bubbles are smaller in size, stay in water for a longer time, and have a more significant oxygenation effect. The surface has a negative charge and strong oxidizing ability, which can effectively degrade pollutants in water. It has a good repairing effect on polluted water bodies. Therefore, the development of micro-nano bubble generating devices is an inevitable trend in the market. [0003] Other micro-nano bubble generation methods at home and abroad include pressurized dissolved air release method, water temperature difference method, electric field method, microwave method, Venturi jet method, etc., based on the above methods, combined with rotary cutting, centrifugation and other devices to prepare micronanobubbles. Among th...
