Description

Micro bubble generator

The present invention relates to an apparatus for generating microbubbles, and more particularly, by first mixing raw water and air to first generate the number of bubbles containing coarse air bubbles in the raw water, and to generate the generated number of bubbles and air by 2 The present invention relates to a microbubble generating apparatus capable of secondaryly generating and supplying the number of air bubbles including microbubbles having a finer size than coarse air bubbles in the air bubble water by secondary mixing.

Dissolved oxygen has an important biological significance because fish and shellfish and aerobic microorganisms breathe using dissolved oxygen in water, and organic matter is oxidatively decomposed by dissolved oxygen. In other words, the lack of dissolved oxygen not only causes the death of fish and shellfish, but also increases organic matter, resulting in fouling of water.

In addition, when dissolved oxygen is insufficient during hydroponic cultivation, absorption of phosphoric acid, potassium, calcium, magnesium, manganese, etc. is not smooth, and the metabolic function of plants is lowered at the root, which adversely affects plant vegetation. On the contrary, when ingesting water rich in dissolved oxygen, it is reported that the rate at which oxygen is absorbed by cells is approximately 5 to 6 times faster than oxygen through respiration, and thus contributes to the activation of the living body.

Therefore, efforts to increase the concentration of dissolved oxygen in water are being actively progressed for use in various fields such as hydroponic cultivation, fish and shellfish farming and preservation, washing, washing, medical care, bathing, food and beverage, etc.

For example, a device that can increase the concentration of dissolved oxygen in water may be a bubble generator used in an aquarium or aquaculture. In the case of a bubble generator, the size of the bubble is adjusted using an air stone to reduce the amount of air and water. The concentration of dissolved oxygen in water can be increased by maximizing contact.

As described above, a method for maximizing the contact between air and water, that is, a method for increasing the concentration of dissolved oxygen in water, is a method of minimizing the size of the bubbles. The bubbles included in the water are micro-bubbles and micro-bubbles depending on their diameter size. It is divided into nano bubbles and nano bubbles.

The smaller the size of the above-described bubbles, the lower the rate of rise (float) and it is easily dissolved in water to increase the concentration of dissolved oxygen in water.In particular, nano bubbles are hardly affected by buoyancy in water due to their fine size. It can remain in water for a long time, thereby making it possible to significantly increase the concentration of dissolved oxygen in the water.

On the other hand, as a device for generating nano-bubbles, a method using a diffuser, a method using a porous body and a frequency, a method using ultrasonic waves, a vibration stirring method, a pressure reduction method, and a chemical spray method have been proposed. Among the methods, except for the method of generating microbubbles using ultrasonic waves, it is known that there is a problem of lack of stability because it is difficult to make the bubbles into nano and the size (diameter) of the bubbles is uneven. There are disadvantages such as having to have a generator.

Therefore, in order to maximize the dissolved oxygen in water, various methods have been developed and researched in order to make the bubbles in water as uniform and stable as possible, while making their size nanoscale.
