Device for generating microbubbles

Abstract

The invention relates to a device for generating micro-bubbles, which comprises a generating cavity, the generating cavity is arranged below a liquid level, a micro-bubble generating layer is arranged on at least part of a contact surface between the generating cavity and liquid, the generating cavity is connected with one end of a pressure supply pipeline, and the other end of the pressure supply pipeline is connected with a pressure sensor. The other end of the pressure supply pipeline is connected with a gas supply device, and gas in the generation cavity penetrates through the micro-bubble generation layer by increasing the gas pressure in the generation cavity and forms micro-bubbles on the contact surface of the micro-bubble generation layer and the liquid; and driving the generating cavity to move in the liquid, and driving the gas in the generating cavity to synchronously move along with the generating cavity so as to cut the micro-bubbles, so that the micro-bubbles enter the liquid. The technical problems that in the micro-bubble cutting process, the energy consumption of driving water to move is high, the input cost is high, and the micro-bubble generating effect is poor are solved.

Description

technical field [0001] The present invention relates to the technical field of micro-bubble generation, in particular to a device for generating micro-bubbles. Background technique [0002] As early as the 1960s, people discovered the existence of micro-nano bubbles and applied them to imaging technology. After 2000, Japan took the lead in researching more characteristics and applications of micro-nano bubbles, and found that micro-nano bubbles have the characteristics of extremely slow rise in water, self-pressurized dissolution, and extremely high mass transfer efficiency (over 95%). It also has the characteristics of greatly improving the solubility of gas, large surface-specific contact area, high interface potential, excellent air flotation effect, reducing the flow resistance of liquid, and explosion in the microscopic field of bubbles breaking the chemical bonds of surrounding water molecules to generate free radicals. [0003] For aquaculture, it can more than doubl...

Problems solved by technology

[0008] Micro-nano bubbles have such an important role, but they have not been popularized and applied on a large scale in actual production. They just stay in the research of application experiments. The core problem is that the energy consumption of micro-nano bubble generators is extremely high, and the increase in production does not increase income.

So far, there has been no breakthrough in the energy consumption of various generators. Most of the micro-nano bubble generators use the high-speed water flow generated by the water pump to cut the gas. The existing design ideas are limited to how to recycle and reuse high-speed Water flow, in essence, can not achieve the purpose of greatly reducing energy consumption

[0010] Aiming at the problems of high energy consumption, high input cost, and poor effect of micro-bubble generation in the related technology of driving water movement during the cutting process of micro-bubbles, no effective solution has been given so far.
