The bubble generation device of the present invention can generate micro-bubbles having a size of nanometer level by a multi-stage bubble generation technique. Specifically, the bubble generating device comprises a first-stage bubble generating unit 1, a second-stage bubble generating unit 2 and a third-stage bubble generating unit 3, wherein the first-stage bubble generating unit 1 can generate bubbles, the second-stage bubble generating unit 2 can crush the bubbles generated by the first-stage bubble generating unit 1 to miniaturize the bubbles, and the third-stage bubble generating unit 3 can further crush the bubbles to form micro-bubbles.
Specifically, the primary bubble generating unit 1 has a bubble generating chamber 101, a water inlet 102, at least one air inlet 103 and a bubble outlet 104, the water inlet 102 and the bubble outlet 104 are respectively communicated with the bubble generating chamber 101 at two opposite sides of the bubble generating chamber 101, and the air inlet 103 is communicated with the bubble generating chamber 101 at the side of the bubble generating chamber 101. When high-speed water flows from the water inlet 102 to the bubble outlet 104 through the bubble generating chamber 101 of the primary bubble generating unit 1, the high-speed water flow can make the bubble generating chamber 101 form a negative pressure environment to allow gas to automatically enter the bubble generating chamber 101 from the air inlet 103, so that the water flow flowing through the bubble generating chamber 101 and the gas entering the bubble generating chamber 101 can be mixed to form bubbles in the bubble generating chamber 101, and the bubbles can be discharged out of the primary bubble generating unit 1 from the bubble outlet 104. That is, when a high-speed water flow flows from the water inlet 102 to the bubble outlet 104 through the bubble generating chamber 101, the bubble generating chamber 101 can form a negative pressure environment to make the gas automatically enter the bubble generating chamber 101 from the gas inlet 103, i.e., the bubble generating chamber 101 can form a negative pressure chamber.
Preferably, the water inlet 102 and the bubble outlet 104 of the primary foaming unit 1 are coaxial, so that a high-speed water flow can directly flow from the water inlet 102 to the bubble outlet 104 through the foaming chamber 101 and allow bubbles formed in the foaming chamber 101 to directly exit the primary foaming unit 1 from the bubble outlet 104.
It is worth mentioning that the number of the air inlets 103 of the primary bubble generating unit 1 is not limited in the bubble generating device of the present invention, and may be one, two or more.
More specifically, the primary bubble generating unit 1 comprises a first bubble generating body 11 and a second bubble generating body 12, the first blister 11 has a first channel 111, the first channel 111 extending through opposite ends of the first blister 11, the second blister 12 has a second channel 121 and at least one third channel 122, the second channel 121 extends through opposite ends of the second blister 12, the third channel 122 communicates the second channel 121 with the outside at the side of the second blister 12, wherein one end of the first blister 11 and one end of the second blister 12 are mounted to each other to form the blister cavity 101 between the first blister 11 and the second blister 12, the first channel 111 of the first blister 11 forms the inlet 102, the second channel 121 of the second blister 12 forms the outlet 104 and the third channel 122 of the second blister 12 forms the inlet 103. Alternatively, the third passage 122 is formed at the end of the first blister 11 so that the third passage 122 formed at the end of the first blister 11 forms the air inlet 103 after one end of the first blister 11 and one end of the second blister 12 are fitted to each other to form the blister cavity 101 between the first blister 11 and the second blister 12.
Preferably, the first passage 111 of the first blister 11 forms the end of the water inlet 102 with a smaller opening size than the other end of the first passage 111, which facilitates the formation of a high velocity water flow when flowing from the first passage 111 of the first blister 11 to the second blister 12. The opening size of the end of the second channel 121 of the second foam generating body 12 where the bubble outlet 104 is formed is smaller than the opening size of the other end of the second channel 121, which facilitates the discharge of a large amount of bubbles from the bubble outlet 104 of the primary foam generating unit 1 out of the primary foam generating unit 1.
In addition, the one-stage bubble generating unit 1 may further include at least one air inlet pipe mounting part 13, the air inlet pipe mounting part 13 is mounted to the third channel 122 of the second bubble generating body 12, and an air inlet pipe can be mounted to the one-stage bubble generating unit 1 through the air inlet pipe mounting part 13 and is communicated with the bubble generating chamber 101.
The secondary bubble generating unit 2 includes a connecting member 21, a plurality of holding columns 22, and a third bubble generating body 23. The connector 21 has a fourth channel 211, the fourth channel 211 penetrates the bubble inlet side 212 and the bubble outlet side 213 of the connector 21, the second bubble generating body 12 is mounted on the bubble inlet side 212 of the connector 21, and the second channel 121 of the second bubble generating body 12 communicates with the fourth channel 211 of the connector 21. Each of the retaining posts 22 extends in the blister side 213 of the connector 21 in spaced relation to form a blister channel 24 between adjacent retaining posts 22. The third bubble generating body 23 is mounted to an end of each of the holding pillars 22 to hold the third bubble generating body 23 in an outlet direction of the fourth passage 211 of the connecting member 21 through each of the holding pillars 22, that is, the fourth passage 211 of the connecting member 21 faces the third bubble generating body 23.
It should be noted that the connection manner of each of the holding posts 22 and the connecting member 21 is not limited, and may be a one-piece structure or a screw-thread mounting structure. Accordingly, the connection manner of each of the holding pillars 22 and the third bubble generating body 23 is not limited, and may be a one-piece structure or a screw-mounting structure.
It is worth mentioning that the surface of the third foam body 23 corresponding to the fourth channel 211 may be a plane surface or a conical surface.
The third stage bubble generating unit 3 includes a fourth bubble generating body 31, the fourth bubble generating body 31 has a fifth channel 311, and the fourth channel 211 penetrates through two opposite ends of the fourth bubble generating body 31 to make the fourth bubble generating body 31 in a cylindrical shape. One end of the fourth foam generating body 31 of the tertiary foam generating unit 3 is attached to the peripheral wall 214 of the secondary foam generating unit 2 such that each of the retaining columns 22 and the third foam generating body 23 of the secondary foam generating unit 2 is located in the fifth passage 311 of the fourth foam generating body 31 of the tertiary foam generating unit 3 and each of the foam discharging passages 24 of the secondary foam generating unit 2 faces the inner wall of the fourth foam generating body 31 of the tertiary foam generating unit 3.
It is worth mentioning that the connection manner of the end of the fourth blister 31 and the peripheral wall 214 of the connector 21 is not limited, and it can be mounted by a screw.
In use of the bubble generating device, a pump body may be mounted to the first bubble generating body 11 of the primary bubble generating unit 1 and communicated with the first passage 111 of the first bubble generating body 11. One end of an air intake pipe is mounted to the air intake pipe mounting part 13 of the primary foaming unit 1 and communicated with the third passage 122 of the second foaming body 12, and the other end of the air intake pipe extends to a position above the water surface. The entire air bubble generating apparatus is immersed below the water surface. The pump body makes the water flow from the water inlet 102 of the primary foaming unit 1 to the foam outlet 104 through the foaming chamber 101, and the opening size of the end of the first channel 111 of the first foaming body 11 forming the water inlet 102 is smaller than the opening size of the other end of the first channel 111, so the self-structure of the first foaming body 11 makes the water flow form a high-speed water flow through the water inlet 102 of the primary foaming unit 1. When a high-speed water flow flows through the bubble making chamber 101 of the primary bubble making unit 1, the bubble making chamber 101 is made to form a negative pressure chamber so that gas automatically enters the bubble making chamber 101 through the gas inlet 103 of the primary bubble making unit 1, so that the water flow flowing through the bubble making chamber 101 and the gas entering the bubble making chamber 101 can be mixed to form bubbles in the bubble making chamber 101, and the bubbles can be discharged out of the primary bubble making unit 1 from the bubble outlet 104. Since the opening size of the end of the second channel 121 of the second bubble generating body 12 where the bubble outlet 104 is formed is smaller than the opening size of the other end of the second channel 121, a large amount of bubbles can be discharged through the bubble outlet 104 of the primary bubble generating unit 1 and flow toward the secondary bubble generating unit 2 through the fourth channel 211 of the connecting member 21 of the secondary bubble generating unit 2. The third foam-making body 23 of the secondary foam-making unit 2 can be crushed by the third foam-making body 23 to form smaller-sized bubbles when being impacted by the third foam-making body 23 during the flow of a large amount of bubbles, and the smaller-sized bubbles can be discharged out of the secondary foam-making unit 2 from the respective bubble discharge passages 24. It will be appreciated that the direction of flow of the smaller sized bubbles exiting the secondary bubble generating unit 2 from each of the bubble exit passages 24 is altered. Then, the smaller-sized bubbles discharged from each of the bubble discharge channels 24 of the secondary bubble generating unit 2 further impinge on the inner wall of the fourth bubble generating body 31 of the tertiary bubble generating unit 3 to form smaller-sized micro-bubbles, and the flow direction of the micro-bubbles is changed to discharge the bubbles along the fifth channel 311 of the fourth bubble generating body 31. Because this bubble generating device is soaked below the water level, because of buoyancy, these micro-bubbles can come up from bottom to top to in the in-process that these micro-bubbles come up, on the one hand, micro-bubbles can take the pollutant in the aquatic of river course out of the water level from bottom to top and be favorable to the natural decomposition of pollutant, and on the other hand, micro-bubbles can accelerate the activity of the aquatic in the river course and further accelerate the decomposition of pollutant in the aquatic.
The invention also provides a bubble generation method, which comprises the following steps:
(1) when high-speed water flows from the water inlet 102 to the bubble outlet 104 of the primary bubble generating unit 1 through the bubble generating chamber 101, the bubble generating chamber 101 forms a negative pressure environment to allow gas to automatically enter the bubble generating chamber 101 through the gas inlet 103 of the primary bubble generating unit 1;
(2) allowing the bubbles to be discharged out of the primary foaming unit 1 through the bubble outlet 104 of the primary foaming unit 1 after the gas and the high-speed water flow are mixed in the foaming chamber 101 to form bubbles;
(3) allowing the bubbles discharged from the primary bubble generating unit 1 through the bubble outlet 104 to collide with the third bubble generating body 23 of the secondary bubble generating unit 2 to form bubbles having a smaller size, and the bubbles having a smaller size are discharged from the bubble discharge passage 24 of the secondary bubble generating unit 2 out of the secondary bubble generating unit 2; and
(4) the bubbles of smaller size, which are allowed to be discharged from the respective bubble discharge passages 24 of the secondary bubble generating unit 2, strike the inner wall of the tertiary bubble generating unit 3 to form minute bubbles.
