Description

Technical Field

[0001] The present application relates to the technical field of physical parameter monitoring, and in particular to a system and method for monitoring the wetting and sedimentation process of fine particles by acoustically stimulating liquid surface vibration. Background Art

[0002] As my country's primary energy source, coal plays an irreplaceable role in safeguarding its energy structure. However, coal dust generated during the mining process, a dangerous and harmful factor, poses a serious threat to the health and safety of underground coal mine workers. In recent years, with the advancement of coal mine mechanization and intelligentization, the intensity of coal mining has increased significantly, and the degree of coal fragmentation has increased significantly, resulting in a sharp increase in dust production during coal mining. Existing dust suppression technologies are not ideal for capturing fine coal dust particles. This is because fine coal dust particles are small in size and tend to float in air currents, making them difficult to settle. Consequently, the dust suppression efficiency of fine coal dust is low.

[0003] A lot of research has been done on the mechanism of synergistic dust reduction by acoustic-chemical spray, but the current research focuses on the effect of acoustic waves on the entrainment pattern of particles and the mechanism of action of chemical spray droplets in coal dust agglomeration. For example, Zhang Guangxue and his team evaluated the effect of acoustic agglomeration by observing the changes in visibility in the experimental chamber before and after the action of acoustic waves, and used electron microscope scanning technology to explore the mechanism of the effect of acoustic excitation on particle agglomeration. However, this method cannot achieve the measurement and analysis of the parameters related to the wetting and deposition of fine particles of coal dust promoted by the vibration of the gas-liquid interface stimulated by acoustic waves. In addition, the technology currently used to monitor the vibration process of the liquid surface mainly relies on laser interferometry, but this method is limited to monitoring the fluctuation of the liquid surface and cannot reveal the influence process of acoustic excitation on the vibration of the liquid surface, nor can it measure the wetting and deposition parameters of coal dust under acoustic excitation.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] like Figure 1 As shown in the functional module diagram, an embodiment of the present application provides a system for monitoring the wetting and sedimentation process of fine particles by acoustic wave-stimulated liquid surface vibration, including: a reaction chamber, an acoustic wave excitation module, a sedimentation test bench and a wetting and sedimentation process monitoring module.

[0030] The sedimentation test bench is arranged in a reaction chamber, and a reagent container is provided on the sedimentation test bench, in which a reagent solution is placed. The acoustic wave excitation module is used to generate an excitation under different acoustic wave parameters on the liquid surface of the reagent solution through the top of the reaction chamber, causing the liquid surface of the reagent solution to vibrate. The sedimentation test bench is also provided with a liftable support frame and a ring tray, on which a qualitative filter paper is provided, and on which evenly distributed coal dust particles are stacked. The liftable support frame is used to drive the ring tray to slowly descend to the liquid surface of the reagent solution, and the qualitative filter paper and the ring tray quickly sink into the reagent solution when they contact the liquid surface of the reagent solution, and then the coal dust particles slowly settle into the reagent solution. The wetting and sedimentation process monitoring module is used to monitor the sedimentation process of the coal dust particles under the excitation of different acoustic wave parameters and determine the sedimentation time of the coal dust particles. In a specific embodiment, the height of the tray can be flexibly adjusted according to the experimental requirements by rotating the knob, so that the coal dust in the tray can be slowly and evenly placed on the liquid surface, thereby achieving precise control of the coal dust sedimentation and wetting and sedimentation processes.

[0031] In an exemplary embodiment of the present application, the acoustic wave excitation module includes an acoustic wave generator, a signal generator, and a power amplifier; the signal generator and the power amplifier are used to generate acoustic waves of different frequencies, different sound pressure levels, different acoustic wave angles, and different waveforms, and the acoustic wave generator is used to excite the liquid surface of the reagent solution. The acoustic wave excitation module can accurately control the acoustic wave parameters (acoustic wave frequency, sound pressure level, acoustic wave angle, waveform) to ensure the uniform distribution and stability of the acoustic waves during the experiment.

[0032] In order to ensure the accuracy of the experiment, sound-absorbing cotton is installed around the reaction chamber to avoid errors caused by sound wave reflection.

[0033] In an exemplary embodiment of the present application, the system for monitoring the wetting and sedimentation process of fine particles by acoustic wave-stimulated liquid surface vibration also includes: a liquid surface vibration monitoring module; the liquid surface vibration monitoring module is used to record the liquid surface vibration parameters of the reagent solution under the excitation of different acoustic wave parameters; the liquid surface vibration parameters include the liquid surface fluctuation frequency and the liquid surface fluctuation height.

[0034] Specifically in this embodiment, the liquid level vibration monitoring module includes: a laser emitter, a reflector, an observation screen, a CCD camera and an image processor; the laser emitter is used to emit a laser beam to the reflector, the reflector is used to reflect the laser beam to the liquid surface of the reagent solution, and then reflected to the observation screen through the liquid surface of the reagent solution, the CCD camera collects the interference fringes displayed on the observation screen and sends them to the image processor, and the image processor is used to determine the liquid level fluctuation frequency and liquid level fluctuation height of the reagent solution according to the changes in the interference fringes.

[0035] This liquid level vibration monitoring module records the interference fringes formed on the observation screen by laser light reflected during liquid surface vibration, thereby monitoring the fluctuations in the reagent solution's surface. When a laser beam from a laser transmitter strikes the liquid surface, the acoustic wave-induced surface vibrations cause changes in the laser's reflection path, resulting in distinct interference fringes. These fringes are projected onto the observation screen and captured by a CCD camera. An image processor analyzes these fringes, accurately measuring the reagent solution's surface vibration pattern and assessing the impact of different acoustic wave parameters on the surface vibration.

[0036] Through the above modules, the monitoring and quantitative analysis of the interface vibration of the dust reduction reagent solution under acoustic wave excitation can be realized. The acoustic wave excitation module can be adjusted to obtain sound waves of different frequencies, sound pressure levels, sound wave angles, and waveforms. The liquid surface vibration monitoring module is used to monitor the fluctuation frequency and height of the liquid surface during the acoustic wave excitation process, and the quantitative display is displayed on the observation screen to obtain the vibration characteristics of the liquid interface under acoustic wave excitation.

[0037] In another exemplary embodiment of the present application, the system for monitoring the wetting and sedimentation process of fine particles by acoustic wave-stimulated liquid surface vibration also includes: an acoustic wave analysis module; the acoustic wave analysis module is used to collect acoustic wave signals in the reaction chamber, and process and analyze the acoustic wave signals to obtain real-time acoustic wave parameters.

[0038] Specifically, in this embodiment, the acoustic wave analysis module includes several acoustic wave probes and a multi-channel noise analyzer. These probes are positioned at different locations within the reaction chamber, measuring acoustic wave signals from these locations and transmitting them to the multi-channel noise analyzer. The multi-channel noise analyzer processes and analyzes the acoustic wave signals from these locations to obtain real-time acoustic wave parameters. Furthermore, the real-time acoustic wave parameters within the reaction chamber can be used to provide feedback and adjust the acoustic wave excitation parameters of the acoustic wave excitation module. This design ensures accurate measurement and continuous monitoring of acoustic wave characteristics during the experiment.

[0039] In a specific embodiment of the present application, the wetting and settling process monitoring module includes: a plurality of high-definition cameras and an image display unit; the plurality of high-definition cameras are positioned at different locations around the reagent container to capture the settling process of coal dust particles in the reagent container from different angles and display the images on the image display unit. In one specific embodiment, the wetting and settling process monitoring module includes four high-definition cameras, one located at each of the four edges of the reaction chamber.

[0040] In a further limited embodiment, the wetting and settling process monitoring module further includes a timing device configured to record the time it takes for the qualitative filter paper and the ring tray to contact the reagent solution surface and the time it takes for the coal dust particles to complete settling, thereby determining the settling time of the coal dust particles. In this embodiment, the wetting and settling process monitoring module observes and records the effect of reagent solution surface vibration on the wetting and settling process under different acoustic excitation parameters. In further embodiments, the module can also be used in conjunction with a viscometer and surface tension meter to study the effect of acoustic excitation on the characteristics of the dust reduction reagent solution.

[0041] The above-mentioned scheme of the present application adopts the laser interference method to realize the liquid surface vibration caused by the propagation of sound waves from the gas phase medium to the liquid phase medium, and realizes the quantitative characterization of the fluctuation frequency and fluctuation height of the liquid surface under the excitation of sound waves. Through this scheme, relevant research on the vibration law of the gas-liquid interface under the excitation of sound waves with different sound wave parameters can be realized. Laser interference technology can capture subtle vibration changes, thereby realizing quantitative analysis of the effect of sound wave excitation. In addition, the excitation disturbance of the liquid surface is realized by the sound wave excitation module, and the dynamic monitoring of the wetting and sedimentation process of the coal dust particles can be realized by the sedimentation process monitoring module. It can realize the research related to the promotion of the wetting of fine particles of coal dust by the vibration of the gas-liquid interface under the excitation of sound waves with different sound wave parameters, filling the gaps in the existing technology.
