Description

Ultra-fine air bubble generator {ULTRA FINE BUBBLE GENERATOR}

The present invention relates to a device for generating bubbles, and more particularly, to maintain a proper flow rate, to generate ultra-fine bubbles with a uniform distribution even with a small pressure, thereby generating a high level of ultra-fine bubbles with less energy. It relates to a device for generating ultra-fine air bubbles.

The ultra-fine bubbles are bubbles with a diameter of 1 μm (1 μm = 1/1000 mm) or less, and are very small in size that cannot be seen with the naked eye. When the same amount of gas is present in the same volume, the surface area is more than 10,000 times larger than that of ordinary bubbles and very light. It has a very high buoyancy and very low buoyancy, so it is very long to float in liquids (up to 6 months).

Due to this, the ultra-fine bubbles remain and dissolve in water for a long time, and the gas dissolution rate is very high due to pressure collapse due to water pressure (the bubbles that remain in the water burst and disappear due to water pressure).

In addition, since the size of the bubble is small, the pressure inside the bubble is high, the ratio of gas liquefaction is high, the dissolution rate is also fast, and the hydrogen viscosity between water molecules is reduced to reduce the viscosity and surface action of the fluid, thereby smoothly absorbing water from plants. I can do it.

The above-mentioned ultra-fine air bubbles include: i) environmental fields such as soil purification, groundwater purification, water purification, wastewater / factory wastewater, livestock wastewater, environmental wastewater treatment, reservoir and river purification, and ii) non-precision electronic parts and semiconductors, etc. -Chemical cleaning, chemical and precision industries such as biodiesel through gas-liquid mixing technology, catalytic process, adsorption and cleaning of harmful substances, synthesis of metal nanoparticles, organic synthesis, emulation technology that does not require surfactants, iii) Completely closed land farms and saltwater freshwater fish farms, promoting aquatic product growth, increasing production, improving quality, maintaining freshness, improving aquaculture, fisheries sectors such as washing fish and shellfish, iv) hydroponics and nutrient solutions, eco-friendly organic cultivation, Agricultural fields such as rapid cultivation, activating plant growth, increasing yield, improving quality, maintaining freshness, removing pesticide residues, v) washing agricultural and marine products, maintaining freshness, preventing oxidation, functional drinks such as hydrogen water, hydrogenation, promoting fermentation, cleaning pores It can be applied to the biomedical industry such as food and hygiene fields such as moisturizing (atopy, companion animal cleaning, etc.), vi) forms of complexes containing medical diagnostic or therapeutic substances, developed for topical diagnosis and topical treatment.

Existing micro-bubble generation method is pressurized dissolution method that is made by depressurizing and then saturating the liquid by applying pressure to the gas, a swirling flow method that rapidly rotates the mixture of liquid and gas, and an air diffuser with minute pores containing the gas in the fluid It is very diverse, such as the acid method of passing through, and the ejector and venturi.

Conventional ultra-fine foam generators have a high level of ultra-fine foam, but the structure from the fluid inlet to the outlet is long and requires a high pressure, so there is a disadvantage in that energy consumption is very high.

The above-described technical configuration is a background technique for helping the understanding of the present invention, and does not mean a conventional technique well known in the art.
