ENVIRONMENT TECHNOLOGY
Fabric collectors use filtration to separe-te dust particulates from dusty gases.
They are one of the most eficiente and cost-effective types of dust collectors and can achieve a collection efficiency of more than 99% for very fine particulates dust-laden gases enter the baghouse and pass through fabric bags that act as filters.
The bags can be of woven or felted cotton, felted polyester, synthetic, glass-fiber material, normaly in a tube shape.
To ensure the filter bags have a long usage life they are commonly coated with a filter enhancer (pre-coat) using a chemically inert limestone (calcium carbonate).
This not only traps fine particulates but also provides protection for the bag itself from moisture and oily or sticky particulates which can bind the filter media.
The pulse jet is the most common type of bag cleaning using a high pressure blasto f air to remove dust from the bag.
