Glass fiber filter cloth bag with round bag bottom is widely used in soot control due to its good heat resistance, high tensile strength and good ash cleaning. In terms of gas filtration, the intensity of the acid decreases greatly, which affects the service life of the filter and limits the application of glass fiber filter in this field.
The newly developed acid-resistant glass fiber filter is treated with an acid-resistant formula. The acid-resistant polymer in the formula is coated on the surface of the glass fiber to form a protective barrier to protect it from chemical attack.
The structure design of the round bag bottom dust bag is generally divided into pulse type dust filter bag, vibrating type dust bag, and reverse blow dust bag according to the different cleaning methods.
Depending on the shape, there are round bag type, flat bag type and envelope type. There are also different design methods of bag mouth and bag bottom for the dust bag.
Application of round bag bottom dust bag:
Flue gas treatment and dust removal systems for ironworks, steelmaking plants, ferroalloy plants, refractory plants, foundries, power plants, etc .;
Filtration of waste gas from incinerators, coal-fired boilers, fluidized bed boilers, etc .;
Asphalt concrete mixing, building materials, cement ceramics, lime, gypsum and other production sites;
Dust management and purification collection in mining, food processing, flour, electronics industry, wood processing, etc .;
Smelting flue gas filtration for aluminum electrolysis, lead, tin, zinc, copper and other rare metals, fine material recovery, liquid and solid separation;
Liquid-solid separation and fine material recovery in chemical, coke, carbon black, dye, pharmaceutical, plastic and other fields.
