Abstract

An apparatus includes a fine bubble generator, a gas supplying source, a first plasma generator, a second plasma generator, a power source and a control module. The fine bubble generator is configured to generate fine bubbles in a liquid. The gas supplying source is configured to supply a working gas. The first plasma generator is configured to generate a first plasma gas from the working gas. The second plasma generator is configured to generate a second plasma gas from the working gas. The power source is configured to supply electricity to the first plasma generator and the second plasma generator. The control module is configured to adjust the power source to provide power to the first plasma generator and the second plasma generator. The first plasma gas and the second plasma gas are directed into the liquid.

Claims (47)

1. An apparatus, comprising:

a fine bubble generator configured to generate fine bubbles in a liquid;

a gas supplying source configured to supply a working gas;

a first plasma generator configured to generate a first plasma gas from the working gas, the first plasma generator comprising:

a first electrode; and

a second electrode, separated from the first electrode by a distance;

a second plasma generator configured to generate a second plasma gas from the working gas;

a power source configured to supply electricity to the first plasma generator and the second plasma generator, the power source comprising a first contact point and a second contact point, the first electrode being electrically connected with the first contact point, the second electrode being electrically connected with the second contact point; and

a control module configured to adjust the power source to provide power to the first plasma generator and the second plasma generator,

wherein the first plasma gas and the second plasma gas are directed into the liquid,

wherein when the first contact point is connected with a power line, the second contact point is connected with a ground line or connected to a ground, or when the second contact point is connected with the power line, the first contact point is connected with the ground line or connected to the ground, and

wherein a range of the distance is between 0.3 mm and 30 mm.

2. The apparatus of claim 1 , further comprising:

a liquid inlet pipe configured to direct the liquid into the fine bubble generator;

a liquid outlet pipe configured to discharge the liquid from the fine bubble generator; and

a gas inlet pipe configured to direct the first plasma gas and/or the second plasma gas into the liquid inlet pipe and/or the liquid outlet pipe.

3. The apparatus of claim 1 , further comprising a gas inlet pipe configured to direct the first plasma gas and/or the second plasma gas into the fine bubble generator, wherein the fine bubble generator is at least partially immersed in the liquid.

4. The apparatus of claim 1 , further comprising a chamber and a switch, the first plasma generator and the second plasma generator are located inside the chamber, the switch is configured to switch the power to the first plasma generator and the second plasma generator.

5. The apparatus of claim 1 , wherein the first plasma generator and the second plasma generator are connected in parallel, the working gas partially flows through the first plasma generator and partially flows through the second plasma generator.

6. The apparatus of claim 1 , wherein the first plasma generator and the second plasma generator are connected in series, the working gas first flows through the first plasma generator and then flows through the second plasma generator, or the working gas first flows through the second plasma generator and then flows through the first plasma generator.

7. The apparatus of claim 1 , further comprising:

a liquid inlet pipe configured to direct the liquid into the fine bubble generator;

a liquid outlet pipe configured to discharge the liquid from the fine bubble generator; and

a gas inlet pipe configured to direct the first plasma gas and/or the second plasma gas into the fine bubble generator.

8. The apparatus of claim 7 , wherein the fine bubble generator is at least partially immersed in the liquid.

9. An apparatus, comprising:

a fine bubble generator configured to generate fine bubbles in a liquid;

a gas supplying source configured to supply a working gas;

a first plasma generator configured to generate a first plasma gas from the working gas;

a second plasma generator configured to generate a second plasma gas from the working gas, the second plasma generator comprising:

a dielectric tube of an insulating material;

an external electrode sleeved outside an outer wall of the dielectric tube; and

an internal electrode extending along an inner wall of the dielectric tube;

a power source configured to supply electricity to the first plasma generator and the second plasma generator, the power source comprising a first contact point and a second contact point, the external electrode being electrically connected with the first contact point, the internal electrode being electrically connected with the second contact point; and

a control module configured to adjust the power source to provide power to the first plasma generator and the second plasma generator,

wherein the first plasma gas and the second plasma gas are directed into the liquid, and

wherein when the first contact point is connected with a power line, the second contact point is connected with a ground line or connected to a ground, or when the second contact point is connected with the power line, the first contact point is connected with the ground line or connected to the ground.

10. An apparatus, comprising:

a fine bubble generator configured to generate fine bubbles in a liquid;

a gas supplying source configured to supply a working gas;

a first plasma generator configured to generate a first plasma gas from the working gas;

a second plasma generator configured to generate a second plasma gas from the working gas;

a power source configured to supply electricity to the first plasma generator and the second plasma generator;

a control module configured to adjust the power source to provide power to the first plasma generator and the second plasma generator;

a chamber, the first plasma generator and the second plasma generator being located inside the chamber; and
