Explanation

It is a kind of materials that uses the role of filtration and adhesion to intercept particles in the fluid to achieve gas-solid separation Id. The main filtering mechanisms are as follows: direct capture, large particles collide with each other and adhere to the surface of the filtering surface of materials, forming a dust layer with filtering effect; Inertial sedimentation. When dusty airflow encounters obstacles during movement and cannot maintain its original streamline trajectory, inertial collisions will occur; Diffusion. When the wind speed is very low, 0. particles are affected by the thermal movement of surrounding gas molecules to produce diffusion; Electrostatic deposition? Filter materials and dust particles deposit due to mutual attraction due to different electrical properties; Van der Waals forces the dust particles to adhere to the fabric. Filter materials mainly include fiber filter materials, porous ceramics filter materials, metallic materials, etc.
