Fiber Demister Pads


Fiber demister pad, also called Fiber Bed Demister Pad or Fiber Bed Candle Filter, it is a continuous duty collector fiber device, which is used for controlling mist and smoke in various manufacturing processes. It can remove the fine particles from a gas stream.

Fiber Demister Pad is composed of two concentric cylinders made of corrosion resistant wire mesh frame. The two cylinder has an approximately 5cm spacing. Then the fiber bed is placed between the spacing. The wire mesh frame can support the fiber bed and it can protect the fiber from shedding even it is used for a long time. In this way, it can extend the service life of the fiber demister pad and improve filtering efficiency.
Fiber Demister Pad filter is placed vertically. When the gas pass through, the trapped liquid particles are filter out the fiber bed. The gases can be filtered from the inside-out or outside-in bed filter according to the site condition and installation ways.

Fiber Demister Pad is commonly supplied in entire structure, which is completely modular. And the detachable design make it is easy to replace the worn fiber bed.

Applications of Fiber Demister Pad

Fiber Demister Pad is suitable for double absorption process in the sulfuric acid absorption tower productions. It can also be used in the chlorine production for eliminating water, drying tower and filtering acid mist.

Fiber Demister Pad is especially suitable for sulfuric acid plants, nitric acid plants, and hot phosphoric acid plant, chlorine and other chemical plants. Pulp mill, textile mills, asphalt saturated tower, food processing, chromium plating process, turbine lubricating oil tank exhaust pipe and plastic molding.
