The nano-microbubble generator comprises a liquid supply device, a gas supply device and a nano-microbubble generator. Wherein, the liquid supply device is used for providing liquid for the nanometer microbubble generator, and the gas supply device is used for providing gas for the nanometer microbubble generator. The mixed gas and liquid pass through a nanometer microbubble generator to generate nanometer-level bubbles. Micro bubbles with the diameter less than 800 μm are divided into micro bubbles (Microbubble) with the diameter of 1 μm to 800 μm and nano bubbles (Nanobubble) with the diameter less than 1 μm. Typical bubbles (diameter greater than 800 μm) float upward in water in a zig-zag or spiral motion, break up upon contact with the water surface and dissolve into the atmosphere. In contrast, microbubbles rise very slowly and gradually dissolve until they disappear during the rise. The floating speed of the nano bubbles is less than the Brownian motion speed, so the nano bubbles can not float in water, can not shrink and disappear at the same time, and can stably exist in the water for a long time.

It is known in many fields that nano bubble water has the characteristics of self-pressurization effect, large specific surface area, slow floating time, negative charge on the surface, high gas dissolution rate, self-increase of dissolution and fracture to generate energy and the like. The characteristics of the nano bubbles are utilized, and the nano bubbles can be widely applied to the multi-field application of aquaculture, soilless culture, fruit and vegetable food cleaning, peculiar smell removal, sterilization and bacteriostasis, beauty and bathing, ecological restoration, sewage treatment, water and soil purification, cleaning in the medical field and the like. In addition, the utility model discloses in the nanometer bubble water that generates can also be applied to the washing in liquid crystal display panel and the semiconductor field.

Particularly, in the field of fishery aquaculture, the control of highly dissolved oxygen in water is a crucial part for the health and growth of fish, the activity and yield of fish can be greatly improved by adopting a nano-bubble technology to replace a traditional oxygen supply mode, and the nano-bubbles have the effects of stimulating the growth of organisms, enhancing the immunity and the like.

Traditional degrease, cleaning process utilize the chemical cleaner to go on, and the oil emulsion in the washing waste water can cause great influence to the environment with remaining the cleaner, and a large amount of clear water are used for the rinsing simultaneously and have also increased the waste of water resource. The micro-nano bubbles have small diameter and low floating speed, have hydrophobic and negatively charged surfaces and can be combined with hydrophobic substances, colloidal substances and the like in water, so the micro-nano bubbles can be applied to the cleaning field.

The nano bubble water can realize harmless sterilization, can not destroy original substances, and can also achieve the aim of sterilization. The residual organophosphorus pesticide in the cleaned vegetables and fruits reacts, the double bonds of pesticide molecules can be broken by the strong oxidation action of a strong oxidant or free radicals, the benzene rings are opened, the molecular structures of the pesticide molecules are destroyed, and corresponding acid, alcohol, amine or oxide and other micromolecular compounds are generated, most of the micromolecular compounds are nontoxic and easy to dissolve in water and can be immediately washed out. Meanwhile, the nano bubble water can kill various bacteria and viruses on the surface. Compared with common ozone water, the ozone water has more remarkable effect of removing residual pesticide attached to fresh fruits and vegetables.

The nano bubbles have the characteristics of slow rising speed, long retention time, high dissolving efficiency, self oxygenation, negative charge, rich free radicals with strong oxidizability and the like in water. The characteristics enable the micro-nano bubbles to be widely applied to water treatment. The micro-nano bubbles not only have high potential generated by surface charge, but also have large specific surface area, so that the micro-nano technology and the coagulation process are combined in wastewater pretreatment, and the micro-nano bubbles have good adsorption effect and efficient removal effect on suspended matters and oils. Hydroxyl free radicals released when the nano bubbles are broken can oxidize and decompose a plurality of organic pollutants, and the application of wastewater treatment, sludge treatment and the like is realized.

The nano bubbles have smaller size and long existence time in water, and can be used for removing micro particles and bacteria attached to the surface of the solid. The nanometer bubbles are used for removing the oxidation microparticles attached to the silicon wafer, pure water is sprayed and cannot be removed, and good cleaning effect can be obtained after the nanometer bubbles are added. In the liquid crystal and semiconductor industries, the nano bubbles can clean residues attached to the surface, fungi and oil stains in a pipeline.

Example one

As shown in fig. 1, the nano-microbubble generator 100 includes a liquid supply device 110, a gas supply device 120, and a nano-microbubble generator 130. Wherein the liquid supply device 110 is used for supplying liquid to the nano-micro bubble generator 130, and the gas supply device 120 is used for supplying gas to the nano-micro bubble generator 130. The mixed gas and liquid passes through the nano-micro bubble generator 130 to generate nano-sized bubbles. Micro bubbles with the diameter less than 800 μm are divided into micro bubbles (Microbubble) with the diameter of 1 μm to 800 μm and nano bubbles (Nanobubble) with the diameter less than 1 μm. Typical bubbles (diameter greater than 800 μm) float upward in water in a zig-zag or spiral motion, break up upon contact with the water surface and dissolve into the atmosphere. In contrast, the micro bubbles rise very slowly and gradually dissolve until disappear during the rising process. The floating speed of the nano bubbles is less than the Brownian motion speed, so the nano bubbles can not float in water, can not shrink and disappear at the same time, and can stably exist in the water for a long time.

The micro-nano bubbles not only have high potential generated by surface charges, but also have large specific surface area, so that the micro-nano technology and the coagulation process are combined in wastewater pretreatment, and the micro-nano bubbles have good adsorption effect and efficient removal effect on suspended matters and oils. Hydroxyl free radicals released when the nano bubbles are broken can oxidize and decompose a plurality of organic pollutants, and the application of wastewater treatment, sludge treatment and the like is realized.

The nano bubbles have a smaller size, so that the nano bubbles can exist in water for a long time, and can be used for removing micro particles 133 and bacteria attached to the solid surface. The oxide microparticles 133 attached to the silicon wafer are removed by using the nano bubbles, and the pure water spray cannot remove the oxide microparticles, so that a good cleaning effect can be obtained after the nano bubbles are added.

Optionally, at least one filter layer 132 is provided at the inflow 1312 and at least one filter layer 132 is provided at the outflow 1313. Optionally, the filter layer 132 is a high-density multi-layer composite filter screen, but may have other structures for filtering. The filter layer 132 can function to filter impurities. Optionally, the material of the filter layer 132 is fiber, sponge, non-woven fabric, stainless steel, glass fiber, metal mesh, composite material, chemical ceramics, PVC, UPVC, or other metal.

Alternatively, particles 133 include, but are not limited to, volcanic rock particles 133, ceramic particles 133, glass particles 133, silicon sphere particles 133, and the like. The filter layer 132 at the inflow port 1312 and the filter layer 132 at the outflow port 1313 can limit the particles 133, and at this time, the plurality of particles 133 are fixed by being pressed at the upper and lower ends. The gas and the liquid are mixed and then pass through the gaps between the particles 133, so that the nano bubbles can be generated more stably. It is noted that the filter layer 132 may be in a semi-encapsulated or other encapsulated form for the particles 133, as desired. The position, shape, thickness, density, and size of the gap (i.e., the size of the filter hole) of the filter layer 132 may be varied according to the actual situation.

In other words, the liquid supply device 110 is connected to the gas supply device 120, and the gas supply device 120 is connected to the nano-microbubble generator 130. The number of the nano-micro bubble generators 130 is at least one, that is, the number of the nano-micro bubble generators 130 can be one, two or more, and the arrangement is flexible according to actual requirements. Alternatively, the number of the nano-microbubble generators 130 is two, and the two nano-microbubble generators 130 are embodied as a first microbubble generator 134 and a second microbubble generator 135.

EXAMPLE III

Particles 133 are volcanic rock particles 133; and/or particles 133 are ceramic particles 133; and/or particles 133 are glass particles 133; and/or particles 133 are silicon sphere particles 133. In other words, the particles 133 may be any one or more of volcanic rock particles 133, ceramic particles 133, glass particles 133, or silica sphere particles 133, and the mixture of the liquid and the gas passes through the particles 133 and the filter layer 132 in the reaction tube 131 to be decomposed into nano-sized bubbles. Specifically, when the mixture of the liquid and the gas passes through the particles 133 in the reaction tube 131, a complex chain reaction such as mutual vibration, compression, and expansion occurs, and nano-scale bubbles are generated.

In another embodiment, the filter layer 132 is a fibrous layer; and/or the filter layer 132 is a sponge layer; and/or the filter layer 132 is a non-woven layer; and/or the filter layer 132 is a stainless steel layer; and/or the filter layer 132 is a chemic ceramic layer. The filter layer 132 may be any one or more of a fiber layer, a sponge layer, a non-woven fabric layer, a stainless steel layer, or a chemical ceramic layer, and on one hand, the structural strength of the filter layer 132 itself can be ensured; on the other hand, the device can play a role of filtering so as to improve the quality of the generated nano-scale bubbles.

In another embodiment, the particle size of the particles 133 is in a range of 0.1mm to 3mm, that is, the particle size of the particles 133 is not less than 0.1mm and not more than 3mm, on one hand, it is ensured that the mixture of the liquid and the gas generates a complex chain reaction of mutual vibration, compression, expansion and the like when passing through the particles 133 in the reaction tube 131, and nano-scale bubbles are generated; on the other hand, it is possible to avoid that the gap between the particles 133 is too narrow due to too small particle diameter, so that a high load is generated when the mixture of the liquid and the gas passes through the particles 133, and the flow rate is remarkably reduced. Alternatively, the average particle diameter of the particles 133 is greater than 1.8mm, gaps between the particles 133 are large, the particle diameter of microbubbles may be greater than 15000nm, and the effect of generating bubbles is not good. Alternatively, when the particle size of the particles 133 is between 1.2mm and 1.5mm, 70% of the generated nanobubbles may have a particle size of less than 800 nm. Alternatively, when the particle size of the particles 133 is between 0.4mm and 0.7mm, 65% of the generated nanobubbles may be less than 200 nm.

In the range of 0.1mm to 3mm, the smaller the particle diameter of the particles 133, the narrower the gap between the particles, the smaller the average particle diameter of the produced nanobubbles, the smaller the minimum particle diameter of the nanobubbles, and the larger the content of the nanobubbles (as shown in table 1)
