| Abstract: | Firstly,factors influencing the application effect of dry filtration and dust removal technology were analyzed,and anexperimental model of dry filtration and dust removal was established.Based on this,an experimental teaching system for dryfiltration and dust removal in underground mining face was designed.We pulsed dust removal,simulated the three sub-systems of the actual roadway.At the same time,parameters such as the length and relative position of the roadway simulation subsystem were optimized by using similar principles.After the system was commissioned,the external conditions such as the relative position of the dust source and the suction fan,the amount of purified air,and the relative humidity were used to simulate the site conditions of the tunneling face.The preset sensors are used to test the filtering resistance,dust removal efficiency,dust removal effect and other parameters of the dry filtration and dust removal system,and to explore the influence of various influencing factors on the application effect of the dry filtration and dust removal system. |
