DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model.

[0022] As shown in the drawings, Figure 1 In one embodiment, a superfine nanometer bubble generator includes a mixer 1 for pre-generating micron-sized and / or micro-nano-sized bubbles;

[0023] A magnetic field activation generator 2 is connected to the mixer 1, and the magnetic field activation generator 2 is used to convert micron-sized and / or micro-nano-sized bubbles entering its interior into superfine nanometer bubbles.

[0024] The magnetic field activation generator 2 includes a tank body 201, the tank body 201 has a liquid inlet 202 and a liquid outlet 203 at both ends, respectively, a strong magnet 204 is arranged inside the tank body 201, the strong magnet 204 is fixed in the tank body 201 by a fixing member 205, and the mixer 1 can be a common Venturi mixer 1 or other types of static mixers 1, preferably a flange type static mixing, the gas and water are mixed by the flange type gas-liquid mixer 1 to generate micron-sized and micro-nano-sized bubbles, and then enter the magnetic field activation generator 2, and after the treatment by the strong magnetic field, the bubbles and micro-nano-sized bubbles dissolved in the water are converted into superfine bubbles or nanometer bubbles with an average diameter of less than 10-150 nm, and preferably the average diameter of the micro-nano-sized bubbles is 20-80 nm.

[0025] Specifically, the super-strong magnetic field usually has a certain magnetic field gradient. The bubbles will be affected by the magnetic field gradient force in this magnetic field gradient. This force will promote the bubbles to move in the direction of the change of the magnetic field strength, and in the moving process, due to the comprehensive influence of the magnetic field on the internal and surrounding environment of the bubbles, the micron-sized bubbles can be gradually compressed and finally converted into nanometer-sized bubbles. In addition, the super-strong magnetic field promotes the micron-sized bubbles to be converted into nanometer-sized bubbles by affecting the liquid properties, gas magnetization, Lorentz force, magnetic field gradient force and surface tension and other factors.

[0026] Optionally, the super-strong magnetic field strength is 1-5T, which can be adjusted according to actual needs.

[0027] As shown in the drawings, Figure 2 In one embodiment, a superfine nanometer bubble generator includes a mixer 1 for pre-generating micron-sized and / or micro-nano-sized bubbles;

[0028] An electric field activation generator 3 is connected to the mixer 1, and the electric field activation generator 3 is used to convert micron-sized and / or micro-nano-sized bubbles entering its interior into superfine nanometer bubbles.

[0029] The electric field activation generator 3 comprises a pipe 304, in which a positive electrode 301 insulated from water and a negative electrode 302 insulated from water are arranged, and the positive electrode 301 and the negative electrode 302 are connected with an external direct current power supply 303 through wires. A low-voltage electrostatic field is formed between the positive electrode 301 and the negative electrode 302, and the low-voltage electrostatic field is used to convert micron-sized and / or micro-nano-sized bubbles into superfine nano bubbles. By using the electrostriction phenomenon, the gas dissolved in water or other fluids forms nano bubbles. The positive and negative electrodes 302 are coated with insulating materials to avoid the electrolysis of water caused by direct contact with water.

[0030] Specifically, when a low-voltage electrostatic field is applied to water containing dissolved gas, water molecules and dissolved gas molecules will be affected by the electric field force. Water molecules are polar molecules and will be arranged in the electric field, while dissolved gas molecules are non-polar but will be affected by the polarization of water molecules. Under the action of the electric field, the dipole moment of the water molecules will tend to arrange along the direction of the electric field. This arrangement will change the interaction between water molecules and affect the environment of the dissolved gas molecules. With the change of polarization and arrangement of water molecules, the dissolved gas molecules will appear supersaturation in the local area. Under the action of the electrostatic field, these supersaturated gas molecules begin to gather together to form small gas nuclei. Under the continuous action of the electrostatic field, these small gas nuclei will continuously adsorb the surrounding gas molecules and gradually grow. Because the action of the electrostatic field on water molecules and gas molecules limits the growth rate and size of the bubbles, eventually nano-sized bubbles are formed. After the formation of nano bubbles, their surfaces will carry charges, which is due to the action of the electrostatic field and the ionization of water molecules on the interface. These charges help the nano bubbles to remain stable in water and prevent them from quickly coalescing or disappearing.

[0031] Optionally, the positive electrode 301 and the negative electrode 302 are both made of titanium or titanium alloy. In the device related to the generation of nano bubbles, if the liquid medium contains corrosive components such as acidic or alkaline substances, the titanium electrode and the functional material coated on the surface can resist corrosion. In the process of generating nano bubbles by using a low-voltage electrostatic field, complex physical and chemical processes are involved, including the polarization of water molecules and the conversion of dissolved gas. The titanium electrode and the functional material coated on the surface will not have unnecessary chemical reactions with the substances in these processes and will not interfere with the bubble generation process, which can ensure that the device stably converts dissolved gas into nano bubbles and improves the solubility of the gas.

[0032] Optionally, the direct current power supply 303 is connected with an external solar panel. Because the energy consumption is low, the solar panel is used to supply the electric field activation generator 3 to work.

[0033] Optionally, the mixer 1 is connected with the electric field activation generator 3 or the magnetic field activation generator 2 through a connecting pipe to ensure that the liquid containing the micro-sized or micro-nano-sized bubbles can enter the electric field activation generator 3 or the magnetic field activation generator 2.

[0034] In one embodiment, the mixer 1 can adopt a gas-liquid mixing pump, and the micro-sized and / or micro-nano-sized bubbles can be converted into superfine nano-sized bubbles by using the gas-liquid mixing pump in cooperation with the electric field activation generator 3.

[0035] The above description of disclosed embodiments enables those skilled in the art to make or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
