First of all, we need to understand the filtration mechanism of the bag filter system: the liquid flows from the inside of the filter bag to the outside of the bag, and the filtered particles are trapped in the bag. The working principle of the bag filter is pressure filtration. The bag filter system mainly comprises three parts: a filter container, a support basket and a filter bag.
The factors affecting the dust removal effect of the bag filter are as follows:
(1) Selection of filter bag: The filter bag should be made of wear-resistant and high-temperature resistant materials, including fiberglass cloth/felt, NOMEX, needle felt, P84 needle felt, etc., taking into account the wear resistance of the filter bag, durability and high temperature. For factors such as cost, the copper industry generally uses NOMEX needle felt.
