Figure 1 The water pump 2 can pump the gas discharged by the liquid bubble generator 1 in the water tank 3 into the testing part 5, and the separated gas can enter the bubble collector 4 from the first outlet of the testing part 5 after being separated by the testing part 5. The bubbles can squeeze the liquid in the bubble collector 4, and the squeezed liquid flows back to the water tank 3. At the same time, the gas not separated by the testing part 5 also flows back to the water tank 3 with the liquid.

[0033] The testing device provided by the above embodiment can judge the separation efficiency of the bubble separator by the amount of bubbles collected in the bubble collector, so as to realize the detection of the separation efficiency of different bubble separators.

[0034] In an optional embodiment, as shown in the figure, Figure 1 The bubble separator separation efficiency testing device further comprises a first pipeline 6, one end of the first pipeline 6 extends into the water tank 3, and the other end is used to communicate with the inlet of the testing part 5. The bubble generator 1 comprises a bubble stone 11, a gas injector 12 and a second pipeline 13, the bubble stone 11 is installed in the first pipeline 6, the gas injector 12 communicates with the bubble stone 11 through the second pipeline 13, and the water pump 2 is installed in the first pipeline 6 and located between the bubble stone 11 and the water tank 3.

[0035] In use, the gas injector 12 can push the gas into the bubble stone 11, so that the bubbles are fully mixed with the liquid pumped out by the water pump 2 and enter the testing part 5.

[0036] The gas injector 12 can be provided with a scale, and the flow rate and total push-in amount of the gas can be controlled by the gas injector 12. The bubble stone 11 can be replaced with different specifications according to different test conditions, such as 100 nm, 150 nm or 200 nm in diameter, etc.

[0037] The flow rate and total push-in amount of the gas controlled by the gas injector 12 can be controlled by adjusting the push-in stroke, push-in speed and push-in time of the gas injector 12.

[0038] The gas injector 12 can comprise a piston, and the delivery of the gas to the bubble stone 11 is realized by the advancement of the piston.

[0042] In an alternative embodiment, as shown in Figure 1 The top of the bubble collector 4 is provided with an exhaust valve 41.

[0043] Before the device is tested, the testing liquid needs to fill the device, so the testing liquid needs to be discharged into the bubble collector 4, at this time, the exhaust valve 41 at the top of the bubble collector 4 can be opened to ensure that the gas in the bubble collector 4 can be smoothly discharged.

[0044] In an alternative embodiment, the bubble collector 4 has a visible side wall for making the internal liquid level visible, which facilitates the tester to observe the liquid level in the bubble collector 4, and further observe how many bubbles are separated from the testing part 5.

[0045] Specifically, the side wall of the bubble collector 4 is provided with a scale, and the scale takes the top end of the side wall of the bubble collector 4 as the 0 scale position.

[0046] Since the bubbles will concentrate at the top of the bubble collector 4 after entering the bubble collector 4, the 0 scale position is arranged at the top end of the side wall of the bubble collector 4, so that the volume of the gas in the bubble collector 4 can be directly read by the reading of the scale, and further the separation efficiency of the testing part 5 can be calculated.

[0047] The formula used to calculate the separation efficiency of the testing part 5 is: separation efficiency = (collected gas volume / injected gas volume) x 100%.

[0053] The end of the fourth pipeline 10 extending into the bubble collector 4 is located at the bottom end of the bubble collector 4, and has a certain height difference with the end of the third pipeline 9 extending into the bubble collector 4, so as to avoid the fourth pipeline 10 directly discharging the gas discharged by the third pipeline 9.

[0054] Specifically, as shown in Figure 1 the test device further comprises a fifth pipeline 011, one end of the fifth pipeline 011 is used to communicate with the second outlet of the test part 5, and the other end extends into the water tank 3.

[0055] The first pipeline 6, the second pipeline 13, the third pipeline 9, the fourth pipeline 10 and the fifth pipeline 011 can be a hose.

[0056] In an optional embodiment, the water tank 3 is provided with a temperature adjusting assembly for adjusting the water temperature in the water tank 3.

[0057] In the above embodiment, the water tank 3 has a temperature adjusting function, and the temperature adjusting range can be -40℃-150℃, which can simulate the temperature of the test liquid during actual use, and ensure that the test result is more accurate.

[0058] The temperature adjusting assembly can include a heating pipe arranged in the water tank, which can heat the test liquid in the water tank, and can also include a refrigeration pipe arranged in the water tank, which can cool the test liquid in the water tank, and the temperature adjusting assembly can also include a temperature sensor for detecting the temperature of the test liquid, so that the water tank 3 can adjust the temperature of the heating pipe and the refrigeration pipe in real time through the detection of the temperature sensor.

[0063] Calculation procedure: calculate the separation efficiency.

[0064] The above test method is simple and low in difficulty, and the test personnel can intuitively observe the gas separation efficiency of the test part 5.

[0065] In an optional embodiment, the preparation step specifically includes:

[0066] Fill the experimental liquid into the water tank 3, replace the bubble stone 11 in the bubble generator 1 with the corresponding test part 5 specification, and install the test part 5;

[0067] Fill the gas injector 12 in the bubble generator 1 with a specified volume of gas, and set the injection gas speed;
