Description

[0001] The present invention relates to a micro-bubble generator and a water quality improving device having the micro-bubble generator,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a micro-bubble generator and a water quality improving apparatus having the micro-bubble generator. More particularly, the present invention relates to a micro-bubble generator for generating and discharging minute bubbles in water passing through a pipe using a venturi effect, The present invention relates to a water quality improving apparatus comprising a micro-bubble generator capable of improving the water quality improvement effect through micro-bubbles by using water containing micro-bubbles discharged from the apparatus.

In general, microbubbles are environmentally friendly energy sources using only water and air, and are made in devices with very small bubbles from 1/100 mm to 1/1000 mm.

These minute bubbles are extremely fine bubbles having a size of 1 micrometer or less unlike bubbles, and micro bubbles are minute bubbles having a diameter of 50 micrometers or less. As a result of the experiment that micro-bubbles can help the blood circulation of the human body, the micro-bubble-based hot spring has been recognized as a sterilizing effect and a biological activity effect by the water including ozone and has become a medical, health, food processing, And so on.

In addition, various pesticide residues remaining on the surface during the washing of vegetables and fruits can be removed, and waste matter remaining on the skin of the human body can be easily discharged, thereby excelling in skin beauty and relaxing fatigue by relaxing the muscles of the human body and relaxation Has been known to help. Various types of micro-bubble generating devices for exploiting the various functions of such micro-bubbles are disclosed.

Such a micro-bubble generating apparatus for generating micro-bubbles generally emits micro-bubbles by injecting pressurized water in which gas and liquid are mixed by a pump into water.

However, in the conventional method, it is difficult to generate a large amount of fine bubbles, and a large amount of energy is required to generate a large amount of fine bubbles.

Conventionally, as a method of generating minute bubbles, there is a method in which pressurized water of high pressure, in which a large amount of air is dissolved in a supersaturated state through a pressurizing pump and a compressor, is produced in a pressurized tank, (DAF) is widely used for blowing air in the form of fine bubbles. Korean Patent Registration No. 10-0155482 and Korean Patent Registration No. 10-0351111 disclose techniques related to the dissolved air floating method .

This dissolved air flotation method is widely used to generate microbubbles up to now, but it requires a lot of manufacturing cost of a pressurized tank, too much energy to produce pressurized water containing air, There is a problem in that a large amount of medicines are consumed and thus a large maintenance cost is required.

In Korean Utility Model Application Publication No. 20-0255929, a gas-liquid mixture formed by mixing air with water to be squeezed through an ejector is injected into a micro-bubble generator having a multi-pore structure, and then a pressurized compressor And the microbubbles are generated due to the decrease of the static pressure generated by passing through the nozzles of the multi-pore tube by applying pressure to the gas-liquid mixture through the nozzle.

In this case, since the pressure of the porous tube is required to be maintained at about 4 to 5 kgf / cm ^2, energy consumption is large and a separate pressurizing tank must be provided, and a large amount of chemicals such as coagulant and neutralizing agent I have a problem.

Korean Utility Model Publication No. 20-0289078 discloses a method of manufacturing pressurized water through a multi-stage pressurizing method using a pressurized pipe, which has a similar problem to that described above.
