{FORMING IMPLEMENT FOR MICRO-BUBBLES} FOR NANO-SIZED BUBBLE GENERATION [0002]

The present invention relates to a hybrid bubble system for generating nano-sized bubbles capable of generating nano-sized bubbles having a long duration of bubbles.

In general, water contains a large amount of air or oxygen (dissolved) so that aquatic plants and animals can be inhabited. Dissolved oxygen is an aerobic microorganism living in water, fish and shellfish breathe through this dissolved oxygen, and the organic matter in water is oxidized and decomposed by this dissolved oxygen. Therefore, the lack of dissolved oxygen contained in water only causes death of fish and shellfish But also organic matter and the like are left behind, resulting in contamination of water.

That is, dissolved oxygen can inhibit the generation of bad bacteria by performing a sterilizing action or a purifying action of water.

In order to utilize the dissolved oxygen contained in the water, the oxygen bubbles are added to the water and applied to various purification facilities, farms or washing machines. In the purification facility, the oxygen bubbles are supplied to the inside of the septic tank, Oxygen bubbles are used to activate the decomposition of wastewater, and in aquaculture farms and the like, the excrement of seafood and the feed that sinks to the bottom are decomposed. Also, in a device such as a washing machine, minute bubbles of oxygen are supplied to the washing water to increase the washing power and sterilize it to some extent.

However, conventionally, oxygen (or air) bubbles have been added to water instead of using dissolved oxygen contained in water in all purification facilities, farms, and washing machines, and oxygen bubbles have been injected into a micrometer- So that the pollutants can be decomposed or sterilized in the water.

In other words, since dissolved oxygen contained in water can not be utilized, oxygen bubbles are generated and further added into water, which requires a device for injecting oxygen bubbles.

That is, conventionally, only a method for utilizing purifying function and sterilizing function by generating minute bubbles by supplying oxygen to water by using a separate apparatus at a high cost, The research on the method of utilizing the bubble size in the meter size is not actively conducted.

Meanwhile, a conventional micro bubble generating apparatus disclosed in Korean Patent Publication No. 10-2010-0101513 (published on Apr. 17, 2010) has an inlet 11 through which liquid containing a gas flows, An inlet 10 made up of an inlet passage; A pressure resistance portion 21 connected to the inflow passage 13 and extending beyond the inflow passage 13 to generate pressure resistance in the liquid, a friction induction portion connected to the pressure resistance portion 21 and generating frictional resistance in the fluid 23) for separating the gas contained in the liquid in a micrometer size; And a micro bubble forming unit (B) including an outlet (30) connected to the friction guide (23).

However, the conventional micro bubble generator has a problem that the inflow passage is long and the supply water passes through the inflow passage for a long time and is in contact with the inner surface of the inflow passage to generate a resistance force, resulting in the extinction of the generated bubbles.

That is, the conventional micro bubble generator actually generates a bubble having a particle size of 10 mu m or less, so that the residence time is only about several minutes, so that a continuous bubble must be supplied.
