Referring to the operation of the nano-bubble multipurpose mixed dissolver 100 using a gas liquid according to an embodiment of the present invention configured as described above in detail as follows.

The oxygen supply unit 160 and the water supply unit 150 supply oxygen and water to the first auxiliary container 141 through the oxygen supply pipe 161 and the water supply pipe 151. The mixture of water and oxygen supplied to the first auxiliary container 141 flows from the upper side to the lower side in the second flow space 145 of the first auxiliary container 141 so that a part of the oxygen is dissolved in water.

At this time, vortices are generated in the water flowing in the second flow space 145 by the plurality of first and

second partitions

Water and oxygen discharged through the first auxiliary container 141 are accommodated in the third flow space 147 of the second auxiliary container 144. At this time, since the third outlet 146 of the first auxiliary container 141 is located below the third flow space 147, oxygen introduced into the third flow space 147 rises upward and comes into contact with water to partially Is dissolved in water.

When the water level of the water contained in the third flow space 147 rises to a position corresponding to the fourth outlet 148, the water and the oxygen dissolved in the third outlet 148 are discharged to the inner container 110. Undissolved oxygen introduced into the inner container 110 is dissolved in water in the first flow space 111 again.

Water and oxygen introduced into the first flow space 111 is discharged to the bottom surface of the outer container 120 by the inner container (110). Water and oxygen discharged to the bottom surface of the outer container 120 is moved to the second discharge port 122 side, it is transported along the flow path formed in a zigzag by the first and second guide members (131,132). At this time, the undissolved oxygen is dissolved in contact with water again.

The first interference protrusion 211 may be formed in a dovetail shape in which the width increases as it protrudes from the edge of the first guide member 210.

The second guide member 220 is located in the inner container spaced apart from each other along the edge to interfere with the mixture passing through the gap between the outer circumferential surface of the inner container 110 to generate a vortex in the flow of the mixture, A plurality of second interference protrusions 221 protruding toward the outer circumferential surface side of 110 are formed. The second interference protrusion 221 may be formed in a dovetail shape in which a width thereof increases as it protrudes from an edge of the second guide member 220.

second outlets

112 and 122 is interrupted by the first and second interfering

protrusions

211 and 221 to generate vortices in the flow, and the dissolution rate of oxygen to water is increased by the vortices. There is this.

Meanwhile, FIG. 5 illustrates first and

second guide members

310 and 320 according to another embodiment of the present invention.

second guide members

310 and 320 are vertically oriented to generate a vortex in the flow of the mixture passing between the outer peripheral surface of the inner container 110 and the inner peripheral surface of the outer container 120. A plurality of through holes 311 are formed through.

Some of the mixture passing through the first and

second guide members

310 and 320 is moved upward through the through hole 311. The flow of the mixture passing through the through hole flows in a direction intersecting the flow of the mixture bypassing the first and

second guide members

310 and 320, thereby generating a vortex in the flow of the mixture. The vortex increases the dissolution rate of oxygen in water.
