Description

Technical Field

[0001] The present invention relates to the technical field of nano bubble generation, and in particular to a method, system and device for controlling the continuous generation of micro-nano bubbles. Background Art

[0002] Nanobubbles are tiny gaseous bubbles with a diameter usually below 100 nanometers. They have unique physical and chemical properties. They can be formed at the interface between liquid and solid, or suspended in liquid. The formation mechanism of nanobubbles is complex and involves many factors, such as surface tension, adsorption and desorption of gas molecules, and liquid-gas-solid interaction at the interface. There are various methods for generating nanobubbles. The pressurized dissolution release method is the most common method for generating micro-nano bubbles. It uses a pump to mix liquid and gas under a certain pressure, so that the gas dissolves in the liquid to form a supersaturated solution (compared with the saturated solubility at atmospheric pressure). When the supersaturated solution is released to atmospheric pressure, micro-nano bubbles can be generated.

[0003] Prior art 1, Chinese patent, application number: 201310737193.4 discloses a method for generating ozone microbubbles, including controlling the volume ratio of gas to liquid input into the gas-liquid mixing pump to be 1:60-1:40, inputting ozone gas and raw water to be treated into the gas-liquid mixing pump respectively and fully mixing them into dissolved gas water; transporting the dissolved gas water from the gas-liquid mixing pump to a pressure dissolved gas tank; maintaining the pressure in the pressure dissolved gas tank at 0.25MPa-0.4MPa, and outputting dissolved gas water from the pressure dissolved gas tank. Although the utilization rate of ozone and the sewage treatment effect are improved, and the equipment cost and operation difficulty are reduced; however, the cost of the gas-liquid mixing pump is very high and its application is limited.

[0004] Prior art 2, Chinese patent, application number 201511035038.3 discloses a flotation pressure dissolved gas device, including a dissolved gas tank, a micro-nano bubble releaser and a reaction tank, the dissolved gas tank is set as a jet-free filler type, the hydraulic retention time in the dissolved gas tank tube is 5-10 seconds, and the normal working pressure in the tube of the dissolved gas tank is 0.25MPa; the dissolved gas saturation rate of the dissolved gas tank is above 80%, an air inlet is set on the dissolved gas tank, a water inlet is set on the dissolved gas tank, and a water outlet is set on the dissolved gas tank, and the water outlet and the micro-nano bubble releaser are set at the bottom of the reaction tank. Although the flotation pressure dissolved gas device is energy-efficient and easy to manage, by improving the dissolved gas tank and the releaser in the existing dissolved gas device, the volume of the dissolved gas tank is reduced and the bubble generation effect is improved, and the removal rate of impurities is increased; but it requires an air compressor, which is noisy and has limited application.

[0005] Prior art three, Chinese patent, application number 202210778793.4 discloses a control method and processor for a micro-nano bubble liquid generation system, the micro-nano bubble liquid generation system includes a liquid inlet flow channel, a liquid outlet flow channel, an air inlet channel, a gas-liquid mixing chamber and a micro-nano bubble liquid generating device, and the control method includes: determining that the liquid outlet flow channel is in a conducting state; determining that liquid flows in the liquid inlet flow channel for the first time; controlling the closing of the liquid inlet flow channel; conducting the air inlet channel to feed air into the gas-liquid mixing chamber; determining that the air intake time reaches the preset air intake time; stopping the air intake into the gas-liquid mixing chamber, conducting the liquid inlet flow channel to feed liquid into the gas-liquid mixing chamber, so that the dissolved gas liquid in the gas-liquid mixing chamber flows out and releases pressure through the micro-nano bubble liquid generating device to form micro-nano bubble liquid. Although the generated micro-nano bubbles have high density and low cost, they are suitable for application in miniaturized equipment; however, a large number of automatic control valves are required, and the application is limited.

[0006] At present, the prior art 1, prior art 2 and prior art 3 have the problems of high cost of gas-liquid mixing pump, need of air pump, high noise, need of a large number of automatic control valves, and limited application. Therefore, the present invention provides a micro-nano bubble continuous generation control system and device, which uses simple system optimization, does not use gas-liquid mixing pump, air pump, and a large number of automatic control valves, and automatically inhales air to achieve continuous generation of micro-nano bubbles.
