When using the bubble generator, the bubble generator is immersed below the water surface, one end of an air inlet pipe can be installed on the second foam generating body 12 through the air inlet pipe installation part 15 of the first stage foam generating part 1 and communicated with the air inlet channel 14, the other end of the air inlet pipe can extend above the water surface, and a water pump is connected to the first foam generating body 11 of the first stage foam generating body 1, so that the water pump can make water flow enter the first channel 111 of the first foam generating body 11.
In particular, in the waterWhen the pump is working, the water pump can make water flow into the first channel 111 of the first bubble-making body 11 of the first stage bubble-making portion 1 to subsequently allow water to flow through the gas pre-storage space 13 to the second channel 121 of the second bubble-making body 12, wherein the flow rate of the water flow can be 1m3/h-100m3H, preferably 10m3/h-50m3H is used as the reference value. Since the range of the ratio of the sectional diameter parameter S1 of the first inlet 112 to the sectional diameter parameter S2 of the first outlet 113 of the first blister 11 is: 36:1 < S1: S2 < 4:1, so that the flow rate of the water flowing into the gas pre-storage space 13 from the first channel 111 of the first foam-making body 11 can be increased to form a high-speed water flow, and the high-speed water flow forms a negative pressure environment in the gas pre-storage space 13 to allow the gas to enter the gas pre-storage space 13 through the air inlet pipe. Since the radial dimension of the gas pre-storage space 13 is larger than the dimension of the first outlet 113 of the first blister body 11 and larger than the dimension of the second inlet 122 of the second blister body 12, the gas pre-storage space 13 can pre-store a portion of the gas and the gas pre-storage space 13 can mix the gas and the high-speed water stream to form bubbles. It can be understood that since the gas reserving space 13 reserves a part of the gas, more gas can be mixed in the high-speed water flow to form a large number of bubbles having a large size. The bubbles with larger size formed in the gas pre-storage space 13 can flow out of the second channel 121 of the second foam generating body 12 and the first bubble channel 24 of the second stage foam generating portion 2 in sequence, and then impact on the first foam generating surface 231 of the baffle plate 23 to form bubbles with smaller size, and the bubbles with smaller size can further exit the second stage foam generating portion 2 through each second bubble channel 25 of the second stage foam generating portion 2. The bubbles of smaller size can be impacted to the second bubble generating surface 31 of the third stage bubble generating portion 3 to be further crushed to form fine bubbles, and the fine bubbles are discharged out of the bubble generator through the bubble generating passage 32 of the third stage bubble generating portion 3. Because the bubble generator is immersed below the water surface, the bubbles can float upwards from bottom to top based on buoyancy, and in the floating process, on one hand, the bubbles can bring out pollutants in the water of the river channel from bottom to topThe water surface is favorable for the natural decomposition of the pollutants, and on the other hand, the air bubbles can accelerate the movement of the water in the river channel so as to further accelerate the decomposition of the pollutants in the water.
