Filtration mechanism
Diffusion deposition: due to Brownian motion, the motion track of each fine particle is inconsistent with the flow direction of compressed air. With the decrease of particle size, the intensity of Brownian motion increases, the probability of collision between fine particles and fibers increases, and the diffusion deposition is stronger.
Direct interception: This mechanism is related to the particle size. When the gap between fibers is smaller than the particle diameter, the particle will be intercepted.
Inertial deposition: when the compressed air passes through the fiber, the streamline will bend. Due to the effect of inertia, the particles in the compressed air will not follow the curved streamline and will be thrown onto the fiber to deposit there. Obviously, this inertial effect will be strengthened with the increase of particle size and compressed air flow rate.
Gravity sedimentation: all kinds of particles have some settling speed due to the effect of gravity, so the movement track of particles deviates from the streamline of compressed air, which can make particles touch fibers.
Electrostatic deposition: particles and fibers may be charged, so particles can be deposited on fibers due to the action or inductive force between charges.
Van der Waals deposition: when the distance between particles and fibers is very small, van der Waals intermolecular force can cause particle deposition. Due to the simultaneous action of the above filtering mechanisms, the fiber filter can filter more than 99%.
