How does air equipment capture dust particles?
How does air equipment capture dust particles?The main method of separation is filtration, i.e. the removal of suspended dust particles and micro-organisms floating in the air through the use of different performance equipment, which is intercepted within a highly efficient filter to ensure that the air sent into the room meets the appropriate cleanliness requirements. Because the filter media used in this equipment are small diameter fibers, the airflow can pass smoothly and the various dust particles can be effectively trapped.Here we will look at the specific capture methods of air filters. 1、Interception: When particles of various diameters move on or near the surface of the fibers when the distance to the surface of the fibers is less than the radius of the particles, the particles will be intercepted by the filter media and thus precipitated. 2, inertia: when the air pollution particles are of greater quality or faster movement, due to the role of inertia collision, resulting in its precipitation on the surface of the fiber. 3, diffusion: small particle size in the air usually Brownian motion, when the movement of faster speed will be easy to collide with the surface of the fiber is captured. 4, gravity: the effect of gravity is believed to be well known, when the pollution particles through the equipment of the fiber layer, because of the role of natural gravity and settling on the surface of the fiber. 5、Electrostatics: The fibers in the equipment or the pollution particles are charged, so the electrostatic effect of attracting the particles will be generated, thus adsorbing the pollution particles to the surface of the fibers. |
