[0037] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0038] The embodiment of the first aspect of the present invention is to provide a bubble separator separation efficiency testing device, such as Figure 1 As shown, it includes a bubble generator 1, a water pump 2, a water tank 3 and a bubble collector 4;

[0039] The water pump 2 is connected to the water tank 3, and the bubble generator 1 is connected to the outlet of the water pump 2. The water pump 2 is used to mix the liquid in the water tank 3 with the gas discharged by the bubble generator 1 and pump the mixture into the test part 5;

[0040] The inlet of the bubble collector 4 is used to communicate with the first outlet of the test part 5, and the outlet at the bottom end of the bubble collector 4 is communicated with the water tank 3;

[0041] The water tank 3 is also used to communicate with the second outlet of the test part 5 .

[0042] When the testing device provided in the above embodiment is used, Figure 1 As shown, the water pump 2 can mix the liquid in the water tank 3 with the gas discharged by the bubble generator 1 and pump it into the test part 5. After the test part 5 is separated, the separated gas can enter the bubble collector 4 from the first outlet of the test part. The bubbles 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 that has not been separated by the test part 5 will also flow back to the water tank 3 with the liquid.

[0043] The testing device provided in the above embodiment can judge the separation efficiency of the bubble separator by the amount of bubbles collected in the bubble collector, thereby realizing the detection of the separation efficiency of different bubble separators.

[0044] In an optional embodiment, if Figure 1 As shown, the bubble separator separation efficiency test device also includes a first pipe 6, one end of which extends into the water tank 3, and the other end is used to communicate with the inlet of the test part 5. The bubble generator 1 includes an air stone 11, a gas injector 12 and a second pipe 13, the air stone 11 is installed in the first pipe 6, the gas injector 12 is connected to the air stone 11 through the second pipe 13, and the water pump 2 is installed in the first pipe 6 and is located between the air stone 11 and the water tank 3.

[0045] When in use, the gas injector 12 can push gas into the air stone 11 , so that the air bubbles are fully mixed with the liquid pumped out by the water pump 2 and enter the test part 5 .

[0046] The gas injector 12 may be provided with a scale, through which the flow rate and the total amount of gas pushed in may be controlled, and the bubble stone 11 may be replaced with different specifications according to different test conditions, such as a diameter of 100nm, 150nm or 200nm.

[0047] The flow rate and total push amount of the gas controlled by the gas injector 12 can be controlled by adjusting the push stroke, push speed and push time of the gas injector 12.

[0048] The gas injector 12 may include a piston, and the gas is delivered to the air stone 11 by pushing the piston.

[0049] In an optional embodiment, if Figure 1 As shown, a flow meter 7 and / or a flow regulating valve 8 is also provided between the air stone 11 and the water pump 2.

[0050] The flow regulating valve 8 can adjust the flow rate of the liquid output by the water pump 2, and the flow meter 7 can be used to measure the liquid flow rate at a certain location.

[0051] In a preferred embodiment, a flow meter 7 and a flow regulating valve 8 are provided between the air stone 11 and the water pump 2 , the flow meter 7 is provided close to the air stone 11 , and the flow regulating valve 8 is provided close to the water pump 2 .

[0052] In an optional embodiment, if Figure 1 As shown, an exhaust valve 41 is provided on the top of the bubble collector 4.

[0053] Before testing the device, the test liquid needs to be filled in the device, so the test liquid needs to be discharged into the bubble collector 4. At this time, the exhaust valve 41 on the top of the bubble collector 4 can be opened to ensure that the gas in the bubble collector 4 can be discharged smoothly.

[0054] In an optional embodiment, the bubble collector 4 has a visible side wall for making the internal liquid level visible. The above arrangement makes it easy for the tester to observe the liquid level in the bubble collector 4 and then observe the amount of bubbles separated by the test part 5.

[0055] Specifically, the side wall of the bubble collector 4 is provided with a scale, and the top of the side wall of the bubble collector 4 is at the 0 scale.

[0056] Since bubbles will gather at the top of the bubble collector 4 after entering the bubble collector 4, the 0 scale is set at the top of the side wall of the bubble collector 4, and the gas volume in the bubble collector 4 can be directly read through the scale reading, and then the separation efficiency of the test part 5 can be calculated.

[0057] The formula used to calculate the separation efficiency of test part 5 is: separation efficiency = (collected gas volume / injected gas volume) x 100%.

[0058] It can be understood that the above-mentioned collected gas volume is the volume of the gas in the bubble collector 4, and the injected gas volume is the total volume of the gas injected by the gas injector 12.

[0059] In an optional embodiment, if Figure 1 As shown, the testing device further includes a third pipe 9 , one end of which extends from the bottom of the bubble collector 4 into the bubble collector 4 and to the top of the bubble collector 4 , and the other end of the third pipe 9 is used to communicate with the first outlet of the test part 5 .

[0060] The third pipe 9 can directly guide the gas separated from the test part 5 to the top of the bubble collector 4 , so that the gas can quickly gather on the top of the bubble collector 4 .

[0061] Of course, the third pipe 9 may also extend to the bottom of the bubble collector 4 .

[0062] Specifically, Figure 1 As shown, the testing device further includes a fourth pipe 10 , one end of the fourth pipe 10 extends from the bottom of the bubble collector 4 into the bubble collector 4 , and the other end of the fourth pipe 10 extends into the water tank 3 .

[0063] The end of the fourth pipe 10 extending into the bubble collector 4 is located at the bottom of the bubble collector 4 and has a certain height difference with the end of the third pipe 9 extending into the bubble collector 4 to prevent the fourth pipe 10 from directly discharging the gas discharged from the third pipe 9.

[0064] Specifically, Figure 1 As shown, the testing device further includes a fifth pipe 011 , one end of which is used to communicate with the second outlet of the testing part 5 , and the other end of which extends into the water tank 3 .

[0065] Among them, the first pipeline 6, the second pipeline 13, the third pipeline 9, the fourth pipeline 10 and the fifth pipeline 011 can be hoses.

[0066] In an optional embodiment, the water tank 3 is provided with a temperature control component, and the temperature control component is used to adjust the water temperature in the water tank 3 .

[0067] In the above embodiment, the water tank 3 has a temperature adjustment function, and the temperature adjustment range can be -40°C to 150°C, which can simulate the temperature of the test liquid when it is actually used, ensuring that the test result is more accurate.

[0068] The temperature control component may include a heating tube arranged in the water tank, which can heat the test liquid in the water tank, and may also include a cooling tube arranged in the water tank, which can cool the test liquid in the water tank. The temperature control component may also include a temperature sensor for detecting the temperature of the test liquid. The temperature sensor can detect and facilitate the water tank 3 to adjust the temperature of the heating tube and the cooling tube in real time.

[0069] The embodiment of the second aspect of the present invention is to provide a method for testing the separation efficiency of a bubble separator using the above-mentioned testing device. The method for testing the separation efficiency of a bubble separator provided by the embodiment of the second aspect of the present invention includes:

[0070] Preparation steps: Install the test part 5 and turn on the water pump 2 to fill the test device with the test fluid;

[0071] Test steps: Open the bubble generator 1 to inject gas and generate bubbles; after the gas injection is completed, stop the experiment after circulating for 1 minute; after the bubbles in the bubble collector 4 are stable, read the volume of the collected gas;

[0072] Calculation steps: Calculate the separation efficiency.

[0073] The test method provided by the embodiment of the second aspect of the present invention is simple to operate and has low difficulty, and the tester can intuitively observe the gas separation efficiency of the test part 5.

[0074] In an optional embodiment, the preparation step specifically includes:

[0075] Pour the test liquid into the water tank 3, replace the bubble stone 11 in the bubble generator 1 with the specification corresponding to the test part 5, and install the test part 5;

[0076] Filling a prescribed volume of gas into the gas injector 12 in the bubble generator 1 and setting the injection gas speed;

[0077] Open the exhaust valve 41 of the bubble collector 4, turn on the water pump 2, and fill the test device with the test liquid. After the air in the bubble collector 4 is exhausted, close the exhaust valve 41 and the water pump 2;

[0078] After the water tank 3 heats the experimental liquid to the specified experimental temperature, the water pump 2 is turned on and adjusted to the specified liquid flow rate, and the system is circulated for 5 minutes to stabilize.

[0079] The above implementation can ensure that the test liquid fills the test system, ensuring that the test process will not be affected by the reserved gas, thereby ensuring the test accuracy.

[0080] It should be noted that before the preparation steps, the experimental conditions can be determined according to the experimental needs, including experimental liquid, experimental temperature, liquid flow rate, injection gas volume, injection gas speed, bubble stone specifications, etc.

[0081] In an optional embodiment, the formula used to calculate the separation efficiency is:

[0082] Separation efficiency = collected gas volume / injected gas volume × 100%.

[0083] Through the above test method, the separation efficiency of different bubble separators can be measured and the separation effect of the bubble separator can be evaluated.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
