Description

Technical Field

[0002] As the main energy source in my country, coal plays an irreplaceable role in the energy structure; however, the coal dust generated during the mining process, as a dangerous and harmful factor, seriously threatens the health and safety of workers in coal mines. In recent years, with the improvement of the mechanization and intelligence level of coal mines, the intensity of coal mining has increased significantly, and the degree of coal body crushing has increased significantly, which has led to a sharp increase in dust production during coal mining. The existing dust reduction technology is not ideal for capturing fine coal dust particles. The reason is that fine coal dust particles are small in size, easy to float with the airflow, and difficult to settle. Therefore, the dust reduction efficiency of fine coal dust particles is low.

[0003] At present, a lot of research has been carried out on the mechanism of synergistic dust reduction of acoustic wave-chemical spray, but the current research focus is mainly on the influence of acoustic waves on the entrainment law 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 cabin before and after the action of acoustic waves, and used electron microscope scanning technology to explore the mechanism of the influence of acoustic wave excitation on the agglomeration effect of particles. However, this method cannot achieve the measurement and analysis of the parameters related to the wetting and sedimentation of fine particles of coal dust promoted by acoustic wave-induced gas-liquid interface vibration. In addition, the current technology used to monitor the liquid surface vibration process mainly relies on laser interferometry, but this method is limited to monitoring the fluctuations of the liquid surface, and cannot reveal the influence of acoustic wave excitation on the liquid surface vibration, nor can it measure the coal dust wetting and sedimentation parameters under acoustic wave excitation.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In order to make the above-mentioned objects, 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 using acoustic wave excitation liquid surface vibration, comprising: 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 the reaction chamber, and a reagent container is arranged on the sedimentation test bench, and a reagent solution is placed in the reagent container. The acoustic wave excitation module is used to generate excitations under different acoustic wave parameters on the liquid surface of the reagent solution through the top of the reaction chamber, causing the liquid surface vibration of the reagent solution; the sedimentation test bench is also provided with a liftable support frame and a circular ring tray, and a qualitative filter paper is arranged on the circular ring tray, and evenly distributed coal dust particles are stacked on the qualitative filter paper; the liftable support frame is used to drive the circular ring tray to slowly descend to the liquid surface of the reagent solution, and the qualitative filter paper and the circular ring tray quickly sink into the reagent solution when contacting the liquid surface of the reagent solution, and then the coal dust particles slowly settle into the reagent solution; the wetting sedimentation process monitoring module is used to monitor the sedimentation process of coal dust particles under the excitation of different acoustic wave parameters, and determine the sedimentation time of coal dust particles.
