Cement industry/lime kiln
Cement raw meal did not completely decompose CACO3 dust in the decomposition furnace, but CaO dust was produced in the decomposition process of CACO.
Gases such as SO, NO, CO, CO2, etc. produced during combustion of pulverized coal for calcination;
The temperature of kiln tail waste gas coming out of cyclone is above 320℃, and the gas is dry;
The dust concentration is 40-130 mg/nm3, and the dust particle size is less than 1 μ m, accounting for more than 90%.
CO and CO2 contents sometimes fluctuate according to the combustion adequacy of pulverized coal.
Cement kiln head: high smoke concentration, strong grindability, high temperature and high humidity. Cement kiln tail: fine dust, difficult to catch, sticky, easy to paste bags, difficult to clean dust, high temperature and easy to fluctuate. The following products are recommended
Product code | processing mode | construction | gram weight(g/㎡) | Air permeability cm³/cm² *S | combustible matter content | Tensile strength | Recommended temperature | |
warp direction | across warp | |||||||
B-01PF | PETF treatment+film coating | Double twill | 750±25 | 2-5 | >10 | >2400 | >2000 | ≤260 |
B-03NF | acid-proof coating | 1/3twill | 340±15 | 2-5 | >10 | >1300 | >800 | ≤260 |
The filter cloth should be selected according to the granularity, density, chemical composition and filtration process conditions of slurry. The strength, elongation, permeability and thickness of filter cloth are different due to the different weaving materials and methods, which affects the filtering effect.
Filter bag manufacturers introduce the types of filter cloth. According to the weaving method, there are monofilament filter cloth, including single multifilament filter cloth, multifilament filter cloth, double-layer filter cloth, non-woven filter cloth and industrial filter belt.
① Monofilament filter cloth: The filter cloth with smooth surface and excellent dewatering property ensures the easy stripping and easy regeneration of filter cake, and is suitable for filter press, leaf filter and all continuous filtering equipment.
② Multi-filament filter cloth: It is suitable for filtering and separating very fine particles. Its wear resistance is called bad monofilament filtration, and it is mainly used in filter presses, centrifuges, drum machines, etc.
③ Double-layer filter cloth: This high-strength filter cloth with good drainage function is specially designed for vacuum belt filter, vacuum drum filter and centrifuge, and has excellent dewatering performance.
④ Non-woven filter cloth: It is suitable for fine particle filtration and flue gas dust removal in ceramics and other industries.
⑤ Industrial filter belt: It is suitable for gypsum dehydration, sewage treatment, starch sugar filtration, pharmacy, brewing, food and beverage and other industries in power plants.
