Functions
The materials used for filtering particulate matter are mineral fiber, natural fiber or synthetic fiber. The filter fiber filter mechanism for filtering particulate matter in the air is divided into five types, and they can work together.
1. Settling effect: Large particles in the air flow are settled on the filter material under the influence of gravity and separated from the air flow.
2. Inertial impact: When the particulate matter in the airflow bypasses the filter fiber that is blocked in front of the airflow, the higher-quality particulate matter will deviate from the direction of the airflow due to the inertia and hit the filter fiber to be filtered.
3. Interception effect: The particles are located on the streamline closest to the filter material in the airflow, and the particles are intercepted by the filter material "scratching" because the radius of the particles is greater than the distance between the streamline and the filter material.
4. Diffusion effect: due to the thermal motion of air molecules, extremely tiny particles are impacted by air molecules, constantly changing the direction of movement, showing Brownian motion, and randomly contacting the filter material fibers to be filtered.
5. Electrostatic effect: If the filter material fiber has weak static electricity, no matter whether the particulate matter in the air flow is static or not, when they are close to the filter material fiber, they are easily attracted by static electricity and are filtered down. The electrostatic effect can help the filter material without increasing the air flow Improve filtration efficiency on the premise of resistance.
