Characteristic

1. High efficiency (mainly capturing particles of 0.5μm or more)

2. Low resistance

3. High dust holding capacity

4. The wind speed uniformity is good

Principle

Interception

The dust particles in the air move with the air flow as inertial motion or random Brownian motion or with some kind of field force. When the particles move into other objects, van der Waals forces exist between the objects (which are molecules and molecules, molecular clusters and The forces between the molecular clusters make the particles stick to the fiber surface. The dust that enters the filter medium has more chance of colliding with the medium and will be stuck when it hits the medium. Smaller dusts collide with each other to form larger particles and settle, and the concentration of dust particles in the air is relatively stable. The fading of the interior and walls is for this reason. It is wrong to treat fiber filters like sieves.

Inertia and diffusion

Particulate dust moves inertially in the air stream. When a disorderly arrangement of fibers is encountered, the air flow changes direction, and the particles deviate from the direction of inertia and hit the fibers and become bound. The larger the particles, the easier it is to impact and the better the effect. Small particles of dust make irregular Brownian movements. The smaller the particles, the more violent the random movement, and the more chance of hitting obstacles, the better the filtering effect. Particles smaller than 0.1 micron in air mainly perform Brownian motion, and the particles are small, and the filtering effect is good. Particles larger than 0.3 μm mainly perform inertial motion, and the larger the particle, the higher the efficiency. Diffusion and inertia are not so obvious that particles are hardest to filter out. When measuring the performance of high-efficiency filters, people often specify the dust efficiency values that are most difficult to measure.
