Description

An amphibious nano-bubble generating device

technical field

The invention relates to the technical field of a bubble generating device, in particular to an amphibious nano-bubble generating device.

Background technique

Due to the characteristics of small bubble size, large specific surface area, high adsorption efficiency, and slow rising speed in water, micro-nano bubbles have physical and chemical characteristics that conventional bubbles do not have. It has important application value in the fields of air flotation water purification, water oxygenation, biopharmaceuticals, precision chemical reactions, lakes, rivers, reservoirs, artificial landscape lakes and other water pollution control.

At present, in water treatment applications that require a large amount of air bubbles and do not require a high diameter range, the commonly used methods are: (1) Impeller air diffusion method: the impeller assembly is used to directly diffuse air to generate micro-bubbles, or combine pressure dissolved air and The impeller disperses the air, and at the same time realizes the three processes of gas-liquid mixing, pressurized air dissolution, and decompression release. The principle of this method is simple, but the actual operation is complicated. Sometimes the bubbles formed are large, and the diameter is difficult to control below 50 μm; (2) High-speed swirl method: the gas-liquid mixed fluid enters the hollow part of the device and rotates, and the difference in specific gravity makes the gas flow in the center. The shaft forms a negative pressure gas shaft, and the gas in the negative pressure gas shaft is cut off and becomes micro-nano bubbles when it passes through the gap between the external liquid and the internal high-speed rotating liquid. This method can quickly generate a large number of micro-nano bubbles, and shows better advantages in terms of bubble concentration and uniformity, and has high efficiency of dissolved oxygen. However, this method relies on high-speed mixing equipment, generally a gas-liquid mixing pump, which is expensive, consumes a lot of energy, and is difficult to process. Moreover, the production of micro-nano bubble water is limited by the flow rate of the pump, so it is not suitable for large-scale production. Application requirements, such as river aeration, etc.

Therefore, in view of the above-mentioned shortcoming in the common prior art, the inventor researches the way of improvement aiming at the above-mentioned shortcoming, finally has the generation of the present invention.
