Ash Dust Collector Filter Bag

Qingdao Star Machiner produces high quality ash dust collector filter bag is the main component in the bag filter system, which is used to capture and filter dust and particles in the air, so as to reduce the dust rate of the flue gas and meet the requirements of environmental protection emission.

Dust particle size, dusty gas temperature, dusty gas humidity, dusty gas corrosivity and other factors will affect the selection of ash dust collector filter bag materials. At the same time, different materials of the filter bag filtration level and service life are not the same, need to take into account the above factors to choose the most suitable ash dust collector filter bag.

How to choose the material of Ash dust collector filter bag:

1. Selection according to the nature of the dust-containing gas:

a. Normal temperature gas less than 130°C :Use PP, PE, Acrylic material to make the ash dust collector filter bag.

b. Medium temperature gas from 130°C to 200°C： Use PPS and Nomex material to make the ash dust collector filter bag.

c. High temperature gas higher than 200°C: Use P84, PTFE and fiberglass material material to make the ash dust collector filter bag

2. Selection of filter bag material according to the nature of dust

a. Short-fibre needle felt for ultra-fine dust

b. Nylon and glass fibre materials are suitable for humid dust.

c. Abrasive dust: suitable for short fibre and thickened felt.

d. Flammable and explosive dust: 2%-5% conductive yarn can be added into the needle felt.
