Description

Technical Field

[0001] The invention relates to a generator, in particular to a supergravity micro-nano bubble generator and a generating system. Background Art

[0002] Micro-nano bubbles can increase the gas-liquid contact area, stimulate biological activity and other important functions. Common methods for producing micro-nano bubbles include the dispersed gas method. The dispersed gas method is to pass the gas through a microporous medium so that the gas forms tiny bubbles on the surface of the microporous medium. However, the tiny bubbles gather and merge into large bubbles on the surface of the microporous medium. In order to solve the problem of aggregation, the microporous medium is usually rotated at a high speed to generate a super strong centrifugal force, so that the generated bubbles quickly break away from the microporous medium; and the high-speed rotating microporous medium can also shear the bubbles in the liquid and reduce the size of the bubbles. However, the microporous medium is usually made of metallurgical powder, ceramics, and plastics sintered at high temperature by adding appropriate adhesives.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] Reference Figure 1 to Figure 4 As shown, this embodiment discloses a supergravity micro-nano bubble generator, including a spiral supergravity tube. A flat channel 5 is provided in the supergravity tube. A microporous medium 6 is laid on the inner wall of the channel 5. An air inlet 11 connected to an external air source is provided on the channel 5 along the spiral direction. A functional module 7 for heating and / or generating ultrasonic waves is provided in the space enclosed by the supergravity tube. High-pressure liquid and gas are simultaneously introduced into the spiral supergravity tube, and a large number of bubbles are generated after the gas passes through the micro-medium pores 6; the generated bubbles are quickly taken away by the high-speed water flow before they grow; and then the spiral motion is performed rapidly, and the centrifugal force generates supergravity, so that the liquid and bubbles are pressed tightly against the microporous medium 6, and the bubbles are further reduced in size under the action of the shear force of the microporous medium 6, so as to obtain a high-concentration micro-nano bubble liquid.

[0029] Specifically, the supergravity tube includes supergravity tube 1, supergravity tube 2, supergravity tube 3, and supergravity tube 4, which are connected in sequence from top to bottom. A plurality of dispersion tubes 12 connected to the channel 5 are arranged on the inner wall of supergravity tube 1 along the spiral direction. The air inlet 11 is inserted into the space enclosed by supergravity tube 1 and is connected to each dispersion tube 12. A liquid inlet 10 is arranged at the upper opening of supergravity tube 1. The top opening of supergravity tube 2 is connected to the bottom opening of supergravity tube 1. Supergravity tube 2 is a conical spiral, and the spiral diameter at the top is the same as the spiral diameter of supergravity tube 1, and is larger than the spiral diameter at the bottom. Supergravity tube 3 is arranged at the bottom of supergravity tube 2. The spiral diameter of supergravity tube 3 is the same as the spiral diameter at the bottom of supergravity tube 2. Functional module 7 is arranged in the space enclosed by supergravity tube 3. The top of the supergravity tube 44 is connected to the bottom of the supergravity tube 33. The supergravity tube 44 is a conical spiral, and the spiral diameter at the top is smaller than the spiral diameter at the bottom. After the dispersion tube 12 generates a large number of bubbles in the channel 5, the supergravity tube 22 with a gradually decreasing spiral diameter gradually increases the angular velocity, so that the centrifugal force gradually increases, so that the bubbles are more tightly pressed on the microporous medium 6, and more dense bubbles are generated; and after the liquid enters the supergravity tube 44, the angular velocity gradually decreases, and the liquid tends to be flat, which is convenient for discharge.

[0030] As a further improvement of this embodiment, the functional module 7 is an ultrasonic generator and / or a heating wire, which is in close contact with the ultra-gravity tube 3 3 .

[0031] The top opening and the bottom opening of the supergravity tube are both provided with a connector unit. The connector unit includes a flange 1 80, a flange 2 85 and a pin shaft 88 arranged on both sides of the opening of the supergravity tube. Flange 1 80 is located on the inner side of the supergravity tube, and a threaded hole 81 is provided thereon. A bolt 82 is air-conditioned in the threaded hole 81. A nut 84 is provided on the bolt 82. Flange 2 85 is located on the outer side of the supergravity tube, and a pin hole 1 86 and a pin hole 2 87 that are interconnected are provided thereon. The caliber of pin hole 1 86 is larger than the caliber of pin hole 2 87. Pin caps 89 are provided at both ends of the pin shaft 88. The caliber of pin hole 1 86 is larger than the caliber of pin cap 89. The caliber of pin shaft 88 is smaller than the caliber of pin hole 2 87. After the flanges 85 of the two super gravity tubes are assembled together, the pin cap 89 is passed through the two flanges 85 from the pin hole 86 and then moved to the pin hole 87; then the bolt 82 is passed through the two flanges 80 and fastened by the nut 84, so as to realize the rapid installation of the two super gravity tubes, which avoids the inconvenience caused when installing inside the spiral.

[0032] As a further improvement of this embodiment, the opposing surfaces of the flange 2 85 when it is assembled with the other flange 2 85 are wedge-shaped surfaces. The pin hole 2 87 is close to the supergravity tube. The pin hole 1 86 is far away from the supergravity tube. When assembled, the two wedge-shaped surfaces overlap each other, and the pin shaft 88 moves outward more smoothly; after the flange 1 80 is tightened, the pin cap 89 is tightly clamped on both sides of the two pin holes 2 87, and the fixation is more secure.

[0033] As a further improvement of this embodiment, a sealing ring 13 is provided on the opening plane of the above-mentioned supergravity tube. The sealing ring 13 surrounds the microporous medium 6. The sealing ring 13 can seal the joint interface of the two supergravity tubes.

[0034] Example 2

[0035] Reference Figure 5 As shown, this embodiment discloses another supergravity micro-nano bubble generator, which includes a supergravity tube consistent with that in embodiment 1, and only when splicing supergravity tube 3 3, multiple supergravity tubes 3 3 are spliced ​​together to form a long-range isotropic spiral supergravity tube. It enables bubbles in the liquid to be fully cut.

[0036] Example 3

[0037] Reference Figure 6As shown, this embodiment discloses another supergravity micro-nano bubble generator, which includes a supergravity tube 1 and a supergravity tube 4 4 ​​consistent with the embodiment 1. Multiple supergravity tubes 4 4 are spliced ​​end to end, and two adjacent supergravity tubes 4 4 are mirror images of each other. The supergravity tube 4 4 ​​at the head end is spliced ​​at the bottom opening of the supergravity tube 1. It can continuously change the angular velocity of the liquid in the tube, thereby changing the magnitude of the centrifugal force exerted on the liquid in real time, increasing the complexity of the liquid flow, and making it easier to generate bubbles.

[0039] Reference Figure 7 As shown, this embodiment discloses a supergravity micro-nano bubble generation system, which includes a generator, a water pump 90, a liquid reservoir 1 91, a gas cylinder 92 and a liquid reservoir 2 93. The liquid reservoir 1 91 is arranged at a high place and is connected to the liquid inlet 10 of the generator. The water pump 90 is arranged on the liquid reservoir 1 91. The gas cylinder 92 is arranged on the gas inlet 11 of the generator. The liquid reservoir 2 93 is arranged on the liquid outlet of the generator. After the water pump 90 pumps the liquid into the liquid reservoir 1 91 located at a high place, the liquid enters the generator at a very fast speed under the action of gravity, generating a strong centrifugal force without generating high pressure through a pump, saving energy; the gas cylinder 92 generates bubbles in the liquid when the liquid enters the generator; the high-concentration micro-nano bubbles generated by the generator are discharged and stored in the liquid reservoir 2 93 for use.
