[0032] Embodiment 1

[0033] Figure 1 FIG. 1 is a structural block diagram of a single bubble evolution detection system provided by an embodiment of the present invention. Figure 1 As shown, a single bubble derivation detection system includes: a multiphase reactor 101, a bubble generating device 102, an image acquisition device 103 and an image processing device 104; wherein,

[0034] The multiphase reactor 101 is used to form a vortex of the pre-configured reaction liquid to generate a target bubble environment;

[0035] The bubble generating device 102 is used to generate a single bubble at a fixed rate, and transmit the single bubble to the target bubble environment generated by the multiphase reactor for derivation;

[0036] The image acquisition device 103 is used to synchronously acquire multiple bubble images based on two different shooting angles during the evolution process of the single bubble, and synchronously send multiple first bubble images acquired at the first shooting angle and multiple second bubble images acquired at the second shooting angle to the image processing device 104;

[0037] The image processing device 104 is used to detect the evolution trajectory of the single bubble in the target bubble environment based on the received first bubble image and the second bubble image, and determine the evolution trajectory information of the single bubble in the target bubble environment.

[0038] In an embodiment of the present invention, the multiphase reactor 101 forms a vortex with the pre-configured reaction liquid to generate a target bubble environment, so as to facilitate more accurate observation of the evolution process of a single bubble. Among them, the multiphase reactor may refer to a chemical reaction device that uses different components to perform chemical reactions. The reaction liquid may refer to a liquid medium used for chemical reactions in a multiphase reactor. The target bubble environment may refer to an environment for subsequent bubble evolution formed by specific operating conditions (such as vortex, temperature, pressure, etc.) in a multiphase reactor. The bubble generating device 102 is used to generate a single bubble at a fixed rate, and transmit the single bubble to the target bubble environment generated by the multiphase reactor for evolution, which can ensure that the bubble remains intact and stable when entering the reactor. Among them, the bubble generating device may refer to a device specially designed to generate a single bubble. The image acquisition device 103 is used to synchronously capture multiple bubble images based on two different shooting angles during the evolution process of the single bubble, and synchronously send multiple first bubble images captured at the first shooting angle and multiple second bubble images captured at the second shooting angle to the image processing device, which can provide more comprehensive bubble information and help subsequent three-dimensional reconstruction and trajectory analysis. Among them, the image acquisition device may refer to a device for capturing and recording bubble images. The image processing device 104 is used to detect the evolution trajectory of the single bubble in the target bubble environment based on the received first bubble image and the second bubble image, and determine the evolution trajectory information of the single bubble in the target bubble environment, thereby realizing accurate detection of the bubble evolution trajectory. Among them, the image acquisition device may refer to a device for performing various processing and analysis on the collected bubble images. The evolution trajectory may refer to the path or trajectory of a single bubble that changes over time in a specific environment (such as the target bubble environment in a multiphase reactor). The evolution trajectory information may refer to various useful information extracted from the evolution trajectory of the bubble. This information may include parameters such as the velocity, acceleration, displacement, and morphological changes of the bubble.

[0039] Optionally, the multiphase reactor includes: a stirred tank reactor, a stirring motor, orthogonal blades and a circular platform, wherein the stirred tank reactor is used to provide an environment for the configuration of the reaction liquid and store pre-configured reaction liquid; the stirring motor is used to provide power for the orthogonal blades and control the rotation speed of the orthogonal blades; the orthogonal blades are used to stir the reaction liquid in the stirred tank reactor so that the reaction liquid forms a vortex to generate a target bubble environment; the circular platform is installed on the top of the orthogonal blades, and is used to generate a uniform flow field to prevent external airflow from entering the target bubble environment.

[0040] Specifically, the stirring motor controls the orthogonal blades to rotate at a preset speed, so that the reaction liquid in the stirred tank reactor forms a vortex, and generates a target bubble environment after the stirring is stable, which helps to form a stable and uniform target bubble environment inside the reactor.

[0041] It should be noted that uniform flow field refers to a flow field state in which the physical quantities such as velocity, direction, density, etc. of the fluid remain relatively consistent or evenly distributed at all positions in the flow field. In the case where the circular platform is installed on top of the orthogonal blades, the generation of a uniform flow field can prevent external airflow from interfering with the target bubble environment, reduce the inhalation of external air, and ensure that a single bubble evolves under stable and controllable conditions.

[0042] For example, Figure 2 As shown, the multiphase reactor may include: a stirred tank reactor A1, a stirring motor A2 and a stirring paddle A3; the inner diameter of the stirred tank A1 may be 206 mm, the height may be 280 mm, and four vertical baffles with a width of 15 mm and a thickness of 2 mm may be installed at equal intervals; the stirring paddle A3 may be an orthogonal blade, with a blade height of 218 mm, a width of 45 mm, and a thickness of 3 mm, the two blades being orthogonal to each other, and a circular platform may be installed on the top of the blade, with a diameter of 90 mm, a thickness of 3 mm, and a height of 2 mm from the bottom.

[0043] Optionally, the bubble generating device comprises: a bubble generator, an air compressor, a pressure regulating valve, a flow meter and a bubble gallery, wherein the air compressor is used to compress air to generate compressed air; the pressure regulating valve is used to control the gas flow and pressure corresponding to the compressed air based on preset bubble parameters to generate a single bubble; the flow meter is used to detect the flow velocity of the single bubble; the bubble generator is used to send the single bubble to the bubble gallery; the bubble gallery is installed at the outlet of the bubble generator, for receiving the single bubble sent by the bubble generator, and transporting the single bubble intact to the stirred tank reactor in the multiphase reactor.

[0044] Among them, the preset bubble parameters may refer to a series of parameters about bubbles set before the bubbles are generated, according to the experimental requirements and the characteristics of the target bubble environment. These parameters usually include the size of the bubble (such as diameter, volume, etc.), shape (such as round, elliptical, etc.), generation rate (such as the number of bubbles generated per second), flow rate (such as the speed at which bubbles move in the fluid), and the distribution pattern of bubbles in the fluid. The bubble gallery may refer to a special channel installed at the outlet of the bubble generator for receiving and transmitting the bubbles generated by the bubble generator.

[0045] Specifically, the pressure regulating valve receives compressed air from the air compressor. According to the preset bubble parameters (such as bubble size, generation rate, etc.), the pressure regulating valve accurately controls the gas flow and pressure of the compressed air. The controlled gas is output through the pressure regulating valve for generating a single bubble. The flow meter is installed at the output end of the pressure regulating valve to detect the gas flow passing through. During the generation of a single bubble, the flow meter can monitor the flow rate of the bubble in real time. The gas controlled by the pressure regulating valve is sent to the bubble generator. The bubble generator uses a specific structure or nozzle design to convert the gas into a single bubble. The generated bubbles are then sent to the bubble gallery for transmission. The bubble gallery is installed at the outlet of the bubble generator to receive the generated bubbles. The bubble gallery has a specific structure and material to ensure that the single bubble remains intact and stable during the transmission process. The single bubble is transported to the stirred tank reactor in the multiphase reactor through the bubble gallery. The various components in the bubble generating device work together to achieve the precise generation, control and transmission of a single bubble.

[0046] For example, Figure 2 As shown, the bubble generating device includes a bubble generator C1, a flow meter C2, a pressure regulating valve C3 and an air compressor C4; the inner diameter of the outlet of the bubble generator C1 can be 6 mm, and a bubble gallery with an inner diameter of 13 mm and a height of 5 mm is arranged around the outlet to allow the bubbles to enter the reactor completely. The height of the bubble generator from the bottom is 60 mm, and it is located in the middle of the blade and the groove wall; the flow meter C2 is a rotor flow meter, and the air compressor C4 is a silent oil-free air compressor with a power of 550-9000 W and a gas volume of 110-600 L / min.

[0047] Optionally, the image acquisition device includes: an external environment determination unit, a synchronization control unit and an image acquisition unit, wherein the external environment determination unit is used to provide a stable external environment for the image acquisition unit; the synchronization control unit is used to synchronously trigger two shooting heads with different shooting angles in the image acquisition unit to start image acquisition; the image acquisition unit is used to calibrate the two shooting heads with different shooting angles based on the external environment, and use the two calibrated shooting heads to synchronously shoot the evolution process of the single bubble to obtain multiple first bubble images under the first shooting angle and multiple second bubble images under the second shooting angle.

[0048] Specifically, under the stable external environment provided by the external environment determination unit for the image acquisition unit, the synchronization control unit synchronously triggers the two shooting heads with different shooting angles in the image acquisition unit to start image acquisition through a precise clock signal or a trigger signal. The synchronization control unit will ensure that the two shooting heads start shooting at the same time, so as to capture the different perspective images of the bubble at the same time point. Before the formal shooting, the image acquisition unit will calibrate the two shooting heads using standard objects or patterns in a known external environment. Lens calibration includes lens distortion calibration, determining the observation range, and then performing size calibration to establish the relationship between the actual physical length and the pixel unit length. The calibration process will calculate the internal and external parameters of the shooting head, such as focal length, principal point position, distortion coefficient, etc., to ensure that the captured image can accurately reflect the true shape and position of the bubble. Under the triggering of the synchronization control unit, the two shooting heads of the image acquisition unit will simultaneously start shooting the evolution process of the bubble. During the shooting process, the two shooting heads will continuously capture the shape and position information of bubbles at different time points according to the preset shooting frequency and shooting time, obtain multiple first bubble images under the first shooting perspective and multiple second bubble images under the second shooting perspective, and realize the accurate capture and recording of the bubble evolution process.

[0049] Optionally, the target bubble environment is a multiphase system composed of at least two phases of gas, liquid and solid; the image acquisition unit is specifically used for: when the target bubble environment is a two-phase environment system composed of gas and liquid, by using two calibrated shooting heads, based on a preset shooting frame number and a preset ventilation rate, the evolution process of the single bubble is synchronously photographed; when the target bubble environment is a three-phase environment system composed of gas, liquid and solid, by using two calibrated shooting heads, based on a preset shooting frame number, a preset ventilation rate and a preset solid phase content, the evolution process of the single bubble is synchronously photographed.

[0050] The preset shooting frame number may refer to the number of times the image acquisition device captures the bubble image per unit time, usually expressed as the number of image frames captured per second (Frames Per Second, fps). The preset ventilation rate may refer to the rate at which gas is introduced into the target bubble environment, usually expressed as the volume of gas introduced per second (such as milliliters per second) or the volume of gas introduced per minute (such as liters per minute). The preset solid phase content may refer to the proportion of solid particles in the target bubble environment, usually expressed as the volume fraction or mass fraction of solid particles.

[0051] Specifically, when the target bubble environment is a two-phase environment system composed of gas and liquid, under the triggering of the synchronization control unit, two calibrated shooting heads are used to synchronously shoot the evolution process of a single bubble in the two-phase environment system according to the preset shooting frame number. At the same time, the gas introduction is controlled according to the preset ventilation rate to generate a stable single bubble. When the target bubble environment is a three-phase environment system composed of gas, liquid and solid, two calibrated shooting heads are used to synchronously shoot the evolution process of a single bubble in the three-phase environment system according to the preset shooting frame number. By comparing the bubble evolution process under different solid phase contents, it is helpful to reveal the influence of solid particles on bubble morphology, motion trajectory and other aspects.

[0052] It should be noted that the gas phase can be air, the liquid phase can be tap water, and the solid phase can be 1mm polymethyl methacrylate particles, which have a high surface reflectivity and are easy to distinguish between the gas and solid phases; the ventilation rate of the gas phase can be 2-5L / min, for example, 2L / min, 3L / min, 4L / min, 5L / min, and the ventilation rate can be adjusted accordingly at different solid phase gas content. The stirring rate can be 300-500r / min, for example, 300r / min, 350r / min, 400r / min, 450r / min, 500r / min. If the stirring speed is too low, it may be difficult to observe the process of bubble breakage. If the stirring speed is too high, a higher camera frame rate is required. The frame interval of 20-50 frames can effectively record the bubble motion trajectory, for example, it can be 20fps, 30fps, 40fps, 50fps, but it is not limited to the listed values. Other values ​​not listed in the numerical range are also applicable. The faster the stirring speed, the shorter the frame interval. The phase content of the solid phase may be 0.1-0.5%.

[0053] Exemplarily, when the target bubble environment is a two-phase environment system consisting of gas and liquid, under the triggering of the synchronization control unit, the evolution process of a single bubble at a speed of 420 rpm and a ventilation rate of 3 L / min is synchronously photographed by using two calibrated shooting heads according to a preset shooting frame number, such as Figure 3 shown. Figure 3 P1 (position1), P2 (position2), etc. refer to the bubble positions of the same bubble at different trajectory points. It can be seen that the bubble will produce obvious oscillations when it leaves the bubble generator, and then continue to move under the entrainment of the fluid and the action of buoyancy. At the same time, it is observed that the morphology of the bubble will produce obvious deformation, but no breakage occurs.

[0054] When the target bubble environment is a three-phase environment system consisting of gas, liquid and solid, the derivatization process of a single bubble at a rotation speed of 420 rpm, a ventilation rate of 3 L / min and a solid content of 0.1% is synchronously photographed by using two calibrated photographing heads according to a preset number of photographing frames, such as Figure 4 shown. Figure 4 P1 (position1), P2 (position2), etc. refer to the bubble positions of the same bubble at different trajectory points. It can be seen that the addition of the solid phase reduces the rising distance of the bubble in the observation window and reduces the number of captureable trajectory points. However, the bubble is always in a rising state as in the gas-liquid two-phase environment.

[0055] When the target bubble environment is a three-phase environment system consisting of gas, liquid and solid, the derivatization process of a single bubble at a rotation speed of 420 rpm, a ventilation rate of 3 L / min and a solid content of 0.2% is synchronously photographed by using two calibrated photographing heads according to a preset number of photographing frames, such as Figure 5 shown. Figure 5 P1 (position1), P2 (position2), etc. refer to the bubble positions of the same bubble at different trajectory points. It can be seen that with the increase of solid concentration, the movement trajectory of the bubble has changed significantly, and the axial velocity has shown negative growth, indicating that the impact of the solid phase on the bubble has become greater.

[0056] Optionally, the external environment determination unit includes: an external square groove, an observation window and a light enhancement device, wherein the external square groove is arranged outside the stirred tank reactor, and is used to eliminate the refraction of light in different media according to the liquid; the observation window is used to determine the observation range of the image acquisition unit; and the light enhancement device is used to enhance the shooting effect of the image acquisition unit.

[0057] The observation window may refer to a transparent window or area, which is set at a specific position outside the stirred tank reactor and is used to determine the observation range of the image acquisition unit. The light enhancement device may refer to a device for improving light intensity and lighting effects.

[0058] For example, Figure 2As shown, the external environment determination unit includes an external square groove D1, an observation window D2 and a light enhancement device B; the parameters of the square groove D1 can be 230mm in length, 230mm in width and 265mm in height; the length, width and height of the observation window D2 can all be 80mm; the light enhancement device B can be a professional photography searchlight EFIII-200, with a maximum power of 200W, and the illumination within 1 meter at full power output can reach 8650Lux. It should be noted that when the length, width and height of the observation window are all 80mm, the lens distortion rate in this area is less than 0.05%, and the process of most bubble breakage can be observed, while most bubbles can pass through.

[0059] It should be noted that the central axes of the two shooting heads with different shooting angles in the image acquisition unit coincide with the central axes of the front plane and the lateral plane of the observation window, respectively. By adjusting the position and angle of the shooting heads, the field of view of the observation window can be maximized to ensure that the captured image can fully reflect the bubble state inside the stirred tank reactor.

[0060] For example, Figure 2 As shown, the image acquisition unit includes two high-speed cameras (or cameras) E1 and a macro lens E2; the central axes of the two high-speed cameras E1 and the macro lens E2 coincide with the central axes of the XZ and YZ planes of the observation window D2 respectively; the relevant parameters of the macro lens E2: magnification 1, lens filter size 62mm, focal length 105mm, graphic distortion rate 0.0345%; the relevant parameters of the high-speed camera E1: CMOS image sensor, resolution 1280×800, maximum frame rate 690000fps. The synchronization control unit includes a trigger switch G1, a three-way head G2 and a switch G3; the synchronization control unit is connected to the trigger switch G1 and the trigger interface of the two high-speed cameras E1 respectively through the BNC female three-way head G1, and can realize synchronous shooting at two vertical angles. The switch G3 is connected to the network ports of the two high-speed cameras respectively, and the trigger switch G1 is electrically connected to the processor F1 and the two high-speed cameras respectively.

[0061] Optionally, the image processing device is specifically used to: extract coordinates of multiple bubble images of a single bubble under the first shooting angle of view to generate a first movement trajectory of the single bubble in the front plane of the observation window; extract coordinates of multiple bubble images of a single bubble under the second shooting angle of view to generate a second movement trajectory of the single bubble in the lateral plane of the observation window; and fuse the coordinates of the first motion trajectory and the second motion trajectory in three-dimensional space to generate a three-dimensional derivative trajectory of the single bubble in the target bubble environment.

[0062] The first motion trajectory may refer to a two-dimensional motion path of a single bubble at a first shooting angle. The second motion trajectory may refer to a two-dimensional motion path of a single bubble at a second shooting angle. The three-dimensional derivative trajectory may refer to a motion path of a single bubble in a three-dimensional space.

[0063] Specifically, coordinates of multiple bubble images of a single bubble under the first shooting angle of view are extracted, and the recorded bubble position coordinates are connected in chronological order to form a first motion trajectory of the bubble in the positive plane of the observation window; coordinates of multiple bubble images of a single bubble under the second shooting angle of view are extracted, and the recorded bubble position coordinates are connected in chronological order to form a second motion trajectory of the bubble in the positive plane of the observation window; coordinates of the first motion trajectory and the second motion trajectory are fused in three-dimensional space, and in the fused three-dimensional coordinate system, the bubble position coordinates are connected in chronological order to form a three-dimensional evolution trajectory of the bubble in the target bubble environment, so as to analyze the evolution process of the bubble from a three-dimensional perspective. A more accurate three-dimensional motion speed of the bubble can be obtained through the three-dimensional perspective, which is beneficial to the analysis of the bubble force and the statistics of the probability of bubble breakage.

[0064] For example, Figure 2 As shown, the image processing device 104 may include a processor F1 and a display F2, wherein the processor F1 is responsible for receiving the bubble image transmitted by the image acquisition unit and issuing a synchronous trigger instruction, and the display may be responsible for displaying the real-time online acquired image and three-dimensional derivative trajectory; the processor F1 is connected to the network ports of the two high-speed cameras through a switch; the trigger switch is electrically connected to the processor and the two high-speed cameras respectively. If there is a bubble tailing phenomenon in the image on the display, the shooting frame rate is adaptively increased; preferably, the camera frame rate of 1000-3000fps can meet the shooting requirements, for example, it can be 1000fps, 1500fps, 2000fps, 2500fps or 3000fps, but it is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable. The higher the frame rate, the lower the camera resolution, which can be adjusted according to the usage; if the image on the display has insufficient brightness, the exposure time of the camera shutter is adaptively extended. Preferably, the exposure time of 60μs can meet the shooting requirements.

[0065] Exemplarily, when the target bubble environment is a two-phase environment system consisting of gas and liquid, the spatial coordinates of a single bubble are extracted based on the synchronous images of the XZ and YZ planes of the observation window, and a three-dimensional derivative trajectory is drawn, such as Figure 6As shown, it can be seen that bubbles can move upward at an axial speed greater than the radial speed under the action of buoyancy. When the target bubble environment is a three-phase environment system consisting of gas, liquid and solid, and the solid phase content is 0.1%, the spatial coordinates of a single bubble are extracted based on the synchronous images of the XZ and YZ planes of the observation window, and the three-dimensional derivative trajectory is drawn, as shown in Figure 7 As shown in the figure, it can be found that due to the momentum transfer between particles and bubbles, the number of bubble trajectory points captured at the same frame interval becomes less, indicating that its radial motion speed is accelerated. When the target bubble environment is a three-phase environment system composed of gas, liquid and solid, and the solid phase content is 0.2%, the spatial coordinates of a single bubble are extracted based on the synchronous images of the XZ and YZ planes of the observation window, and the three-dimensional derivative trajectory is drawn, as shown in Figure 8 As shown, it can be found that due to the negative growth of the axial velocity, the bubbles stay in the reactor longer, because within the same frame interval, the number of trajectory points captured by the observation window increases; in addition, under the action of the particles, the movement direction of the bubbles along the Y axis also changes, and the speed and force of the bubbles will also change.

[0066] The single bubble derivation detection system provided in the embodiment of the present invention comprises: a multiphase reactor, a bubble generating device, an image acquisition device and an image processing device; wherein the multiphase reactor is used to form a vortex with a pre-configured reaction liquid to generate a target bubble environment, so as to facilitate more accurate observation of the derivation process of a single bubble. The bubble generating device is used to generate a single bubble at a fixed rate, and transmit the single bubble to the target bubble environment generated by the multiphase reactor for derivation, which can ensure that the bubble remains intact and stable when entering the reactor. The image acquisition device is used to synchronously capture multiple bubble images based on two different shooting angles during the derivation process of the single bubble, and synchronously send multiple first bubble images captured under the first shooting angle and multiple second bubble images captured under the second shooting angle to the image processing device, which can provide more comprehensive bubble information and facilitate subsequent three-dimensional reconstruction and trajectory analysis. The image processing device is used to detect the derivation trajectory of the single bubble in the target bubble environment based on the received first bubble image and second bubble image, and determine the derivation trajectory information of the single bubble in the target bubble environment, so as to achieve accurate detection of the bubble derivation trajectory. Through the coordinated work of the multiphase reactor, bubble generating equipment, image acquisition equipment and image processing equipment, the evolution trajectory of a single bubble in the target bubble environment is accurately detected, which facilitates the analysis of the evolution trajectory of a single bubble, thereby facilitating further analysis of the force and breakage probability of the bubble.

[0067] Optionally, the image processing device is also used to: determine target derivative information of the single bubble based on the derivative trajectory information of the single bubble in the target bubble environment, the target derivative information including: a derivative trajectory graph, a velocity change graph and an acceleration change graph of the single bubble in the target bubble environment; and display the target derivative information in a visual interface.

[0068] Specifically, based on the three-dimensional derivative trajectory that has been generated, the image processing device first extracts the detailed trajectory information of the bubble in the target bubble environment, including position coordinates, timestamps, etc. The instantaneous velocity of a single bubble in each time period is calculated using adjacent position coordinates and timestamps. Through interpolation or smoothing, the velocity change curve of a single bubble in the entire derivative process is obtained. The velocity change curve is differentiated to obtain the instantaneous acceleration of a single bubble in each time period. Similarly, through interpolation or smoothing, the acceleration change curve of a single bubble in the entire derivative process is obtained. The trajectory information of a single bubble is plotted in three-dimensional space to form a derivative trajectory diagram. The velocity change curve and the acceleration change curve are plotted into graphs respectively to intuitively display the velocity and acceleration changes of the bubble. The target derivative information is displayed in a visual interface.

[0069] For example, when the target bubble environment is a two-phase environment system consisting of gas and liquid, the bubble velocity is counted based on the camera frame rate of 2000fps and the photo frame interval of 20fps, that is, the time interval between the two photos is 0.01s, and the three-dimensional motion velocity and acceleration distribution diagram is drawn as follows: Fig. 9 As shown in the figure, it can be seen that the bubble will undergo a large deformation when it just leaves the bubble generator, and the acceleration at this time is also large. As the bubble continues to move in the reactor, the acceleration will gradually increase as the bubble approaches the wall position, and the bubble deformation at this time is also relatively large, indicating that the bubble is easier to break at the wall position. The bubble speed will increase as the bubble residence time increases.

[0070] When the target bubble environment is a three-phase environment system consisting of gas, liquid and solid, if the solid phase content is 0.1%, the bubble velocity is statistically analyzed based on the camera frame rate of 2000fps and the photo frame interval of 20fps, that is, the time interval between the two photos is 0.01s, and the three-dimensional motion velocity and acceleration distribution diagram is drawn as follows: Fig.10 As shown, it can be found that the acceleration change of bubbles is smoother than that of the gas-liquid two phases.

[0071] When the target bubble environment is a three-phase environment system consisting of gas, liquid and solid, if the solid phase content is 0.2%, the bubble velocity is statistically analyzed based on the camera frame rate of 2000fps and the photo frame interval of 20fps, that is, the time interval between the two photos is 0.01s, and the three-dimensional motion speed and acceleration distribution diagram is drawn as follows: Fig.11 As shown, it can be found that with the increase of solid particle concentration, the bubble velocity even shows negative growth, which means that the particles will hinder the movement of bubbles and the existence of particles is not conducive to the breakage of bubbles.

[0072] Embodiment 2

[0073] This embodiment provides a single bubble derivation detection method based on the single bubble derivation detection system provided in the above embodiment. Fig.12 A schematic diagram of a flow chart of a single bubble derivation detection method provided by an embodiment of the present invention, such as Fig.12 As shown, the method comprises the following steps:

[0074] S210, forming a vortex of the pre-configured reaction liquid through a multiphase reactor to generate a target bubble environment.

[0075] Specifically, the pre-configured reaction liquid can be formed into a vortex through a multiphase reactor. The generation of the vortex helps to form a stable and uniform target bubble environment inside the reactor. The stable and uniform bubble environment helps to reduce the interaction between bubbles, so as to more accurately observe the evolution process of a single bubble.

[0076] Exemplarily, the "multiphase reactor" in S210 may include: a stirred tank reactor, a stirring motor, orthogonal blades and a circular platform, wherein the stirred tank reactor is used to provide an environment for the configuration of the reaction liquid and store pre-configured reaction liquid; the stirring motor is used to provide power for the orthogonal blades and control the rotation speed of the orthogonal blades; the orthogonal blades are used to stir the reaction liquid in the stirred tank reactor so that the reaction liquid forms a vortex to generate a target bubble environment; the circular platform is installed on the top of the orthogonal blades to prevent external airflow from entering the target bubble environment by generating a uniform flow field.

[0077] Specifically, the stirring motor controls the orthogonal blades to rotate at a preset speed, so that the reaction liquid in the stirred tank reactor forms a vortex, which helps to form a stable and uniform target bubble environment inside the reactor.

[0078] S220, generating a single bubble at a fixed rate through a bubble generating device, and transmitting the single bubble to a target bubble environment generated by the multiphase reactor for derivation.

[0079] Specifically, the bubble generating device generates single bubbles at a fixed rate by precisely controlling the flow rate and pressure of the gas, and the generated single bubbles are sent into the target bubble environment in the multiphase reactor for derivation.

[0080] Exemplarily, the "bubble generating device" in S220 may include: a bubble generator, an air compressor, a pressure regulating valve, a flow meter and a bubble gallery, wherein the air compressor is used to compress air to generate compressed air; the pressure regulating valve is used to control the gas flow and pressure corresponding to the compressed air based on preset bubble parameters to generate a single bubble; the flow meter is used to detect the flow rate of the single bubble; the bubble generator is used to send the single bubble to the bubble gallery; the bubble gallery is installed at the outlet of the bubble generator, for receiving the single bubble sent by the bubble generator, and transporting the single bubble intact to the stirred tank reactor in the multiphase reactor.

[0081] Specifically, the pressure regulating valve receives compressed air from the air compressor. According to the preset bubble parameters (such as bubble size, generation rate, etc.), the pressure regulating valve accurately controls the gas flow and pressure of the compressed air. The controlled gas is output through the pressure regulating valve for generating a single bubble. The flow meter is installed at the output end of the pressure regulating valve to detect the gas flow passing through. During the generation of a single bubble, the flow meter can monitor the flow rate of the bubble in real time. The gas controlled by the pressure regulating valve is sent to the bubble generator. The bubble generator uses a specific structure or nozzle design to convert the gas into a single bubble. The generated bubbles are then sent to the bubble gallery for transmission. The bubble gallery is installed at the outlet of the bubble generator to receive the generated bubbles. The bubble gallery has a specific structure and material to ensure that the single bubble remains intact and stable during the transmission process. The single bubble is transported to the stirred tank reactor in the multiphase reactor through the bubble gallery. The various components in the bubble generating device work together to achieve the precise generation, control and transmission of a single bubble.

[0082] S230. During the evolution process of the single bubble, a plurality of bubble images are synchronously acquired based on two different shooting angles through an image acquisition device, and the plurality of first bubble images acquired under the first shooting angle and the plurality of second bubble images acquired under the second shooting angle are synchronously sent to an image processing device.

[0083] Specifically, the image acquisition device can be arranged at an appropriate position of the multiphase reactor, and can synchronously acquire multiple bubble images based on two different shooting angles. The two different shooting angles can provide more comprehensive bubble information, which is helpful for subsequent three-dimensional reconstruction and trajectory analysis. The synchronous acquisition of multiple images can capture the continuous changes of bubbles during the evolution process, providing time series data for subsequent analysis.

[0084] Exemplarily, the "image acquisition device" in S230 may include: an external environment determination unit, a synchronization control unit and an image acquisition unit, wherein the external environment determination unit is used to provide a stable external environment for the image acquisition unit; the synchronization control unit is used to synchronously trigger two shooting heads with different shooting angles in the image acquisition unit to start image acquisition; the image acquisition unit is used to calibrate the two shooting heads with different shooting angles based on the external environment, and use the two calibrated shooting heads to synchronously shoot the evolution process of the single bubble to obtain multiple first bubble images under the first shooting angle and multiple second bubble images under the second shooting angle.

[0085] Specifically, under the stable external environment provided by the external environment determination unit for the image acquisition unit, the synchronization control unit synchronously triggers the two shooting heads with different shooting angles in the image acquisition unit to start image acquisition through a precise clock signal or a trigger signal. The synchronization control unit ensures that the two shooting heads start shooting at the same time, so as to capture the images of the bubbles at different angles at the same time point. Before the formal shooting, the image acquisition unit will calibrate the two shooting heads using standard objects or patterns in the known external environment. The calibration process will calculate the internal and external parameters of the shooting heads, such as focal length, principal point position, distortion coefficient, etc., to ensure that the captured image can accurately reflect the true shape and position of the bubble. Under the triggering of the synchronization control unit, the two shooting heads of the image acquisition unit will simultaneously start shooting the evolution process of the bubble. During the shooting process, the two shooting heads will continuously capture the shape and position information of the bubble at different time points according to the preset shooting frequency and shooting time, obtain multiple first bubble images under the first shooting angle and multiple second bubble images under the second shooting angle, and realize the accurate capture and recording of the bubble evolution process.

[0086] Exemplarily, the target bubble environment is a multiphase system composed of at least two phases of gas, liquid and solid; the image acquisition unit is specifically used for: when the target bubble environment is a two-phase environment system composed of gas and liquid, by using two calibrated shooting heads, based on a preset shooting frame number and a preset ventilation rate, the evolution process of the single bubble is synchronously photographed; when the target bubble environment is a three-phase environment system composed of gas, liquid and solid, by using two calibrated shooting heads, based on a preset shooting frame number, a preset ventilation rate and a preset solid phase content, the evolution process of the single bubble is synchronously photographed.

[0087] Specifically, when the target bubble environment is a two-phase environment system composed of gas and liquid, under the triggering of the synchronization control unit, two calibrated shooting heads are used to synchronously shoot the evolution process of a single bubble in the two-phase environment system according to the preset shooting frame number. At the same time, the gas introduction is controlled according to the preset ventilation rate to generate a stable single bubble. When the target bubble environment is a three-phase environment system composed of gas, liquid and solid, two calibrated shooting heads are used to synchronously shoot the evolution process of a single bubble in the three-phase environment system according to the preset shooting frame number. By comparing the bubble evolution process under different solid phase contents, it is helpful to reveal the influence of solid particles on bubble morphology, motion trajectory and other aspects.

[0088] Exemplarily, the external environment determination unit includes: an external square trough, an observation window and a light enhancement device, wherein the external square trough is arranged outside the stirred tank reactor, and is used to eliminate the refraction of light in different media according to the liquid; the observation window is used to determine the observation range of the image acquisition unit; and the light enhancement device is used to enhance the shooting effect of the image acquisition unit.

[0089] It should be noted that the central axes of the two shooting heads with different shooting angles in the image acquisition unit coincide with the central axes of the front plane and the lateral plane of the observation window, respectively. By adjusting the position and angle of the shooting heads, the field of view of the observation window can be maximized to ensure that the captured image can fully reflect the bubble state inside the stirred tank reactor.

[0090] S240. Using the image processing device, based on the received first bubble image and the second bubble image, detect the evolution trajectory of the single bubble in the target bubble environment to determine the evolution trajectory information of the single bubble in the target bubble environment.

[0091] Specifically, the image processing device receives the first bubble image and the second bubble image from the image acquisition device. The image processing device can further determine the evolution trajectory of a single bubble in the target bubble environment through algorithms such as image matching, feature extraction, and trajectory tracking, and determine the evolution trajectory information of the single bubble in the target bubble environment. The acquisition of the evolution trajectory information helps researchers to gain a deeper understanding of the behavior characteristics of bubbles in a specific environment, and provides an important basis for subsequent experimental design and optimization.

[0092] Exemplarily, the "image processing device" in S240 is specifically used to: extract coordinates of multiple bubble images of a single bubble under the first shooting angle of view to generate a first movement trajectory of the single bubble in the front plane of the observation window; extract coordinates of multiple bubble images of a single bubble under the second shooting angle of view to generate a second movement trajectory of the single bubble in the lateral plane of the observation window; and coordinately fuse the first motion trajectory and the second motion trajectory in three-dimensional space to generate a three-dimensional derivative trajectory of the single bubble in the target bubble environment.

[0093] Specifically, coordinates of multiple bubble images of a single bubble under the first shooting angle are extracted, and the recorded bubble position coordinates are connected in chronological order to form a first motion trajectory of the bubble in the positive plane of the observation window; coordinates of multiple bubble images of a single bubble under the second shooting angle are extracted, and the recorded bubble position coordinates are connected in chronological order to form a second motion trajectory of the bubble in the positive plane of the observation window; coordinates of the first motion trajectory and the second motion trajectory are fused in three-dimensional space, and in the fused three-dimensional coordinate system, the bubble position coordinates are connected in chronological order to form a three-dimensional derivative trajectory of the bubble in the target bubble environment.

[0094] The single bubble evolution detection method provided in the embodiment of the present invention forms a vortex with the pre-configured reaction liquid through a multiphase reactor to generate a target bubble environment, so as to facilitate more accurate observation of the evolution process of a single bubble. A single bubble is generated at a fixed rate through a bubble generating device, and the single bubble is transmitted to the target bubble environment generated by the multiphase reactor for evolution, which can ensure that the bubble remains intact and stable when entering the reactor. Through an image acquisition device, during the evolution process of the single bubble, multiple bubble images are synchronously acquired based on two different shooting angles, and multiple first bubble images acquired under the first shooting angle and multiple second bubble images acquired under the second shooting angle are synchronously sent to an image processing device, which can provide more comprehensive bubble information and contribute to subsequent three-dimensional reconstruction and trajectory analysis. Through an image processing device, based on the received first bubble image and second bubble image, the evolution trajectory of the single bubble in the target bubble environment is detected, and the evolution trajectory information of the single bubble in the target bubble environment is determined, thereby realizing accurate detection of the bubble evolution trajectory, facilitating analysis of the evolution trajectory of a single bubble, and thus facilitating further analysis of the force and breakage probability of the bubble.

[0096] Specifically, based on the three-dimensional derivative trajectory that has been generated, the image processing device first extracts the detailed trajectory information of the bubble in the target bubble environment, including position coordinates, timestamps, etc. The instantaneous velocity of a single bubble in each time period is calculated using adjacent position coordinates and timestamps. Through interpolation or smoothing, the velocity change curve of a single bubble in the entire derivative process is obtained. The velocity change curve is differentiated to obtain the instantaneous acceleration of a single bubble in each time period. Similarly, through interpolation or smoothing, the acceleration change curve of a single bubble in the entire derivative process is obtained. The trajectory information of a single bubble is plotted in three-dimensional space to form a derivative trajectory diagram. The velocity change curve and the acceleration change curve are plotted into graphs respectively to intuitively display the velocity and acceleration changes of the bubble.
