In the field of bag dust, usually the bag is more than the heart of the bag filter, bag filter can handle what kind of dust, mainly depends on the chemical fiber used to make the bag itself conditions. General flue gas temperature conditions, only need to bag the temperature can withstand 150 below, these occasions, polyester, polypropylene, acrylic, nylon and other chemical fibers can be basically qualified. For the relatively high flue gas temperature occasions, such as: chemical, carbon black (silica) tail gas, iron ore blast furnace gas, cement kiln kiln gas, calcium carbide kiln exhaust, casting, steel smelting, asphalt Concrete mixing asphalt flue gas, refractory brick furnace flue gas, coking flue gas, etc., because these dusty dust due to resistance than the resistance is not suitable for electrostatic precipitator collection, can only use bags or other means to collect; Second, if the dust flue gas temperature to 150 below the higher investment or by the site of the restrictions; Third, because the dust in the flue gas because of the composition of sulfur, dust flue gas with acid "dew point" containing Dust flue gas can only be in the acid dew point above the higher temperature of the filter separation and other factors, so you need to have a higher temperature of the chemical fiber used to make the filter. My company selected DuPont Teijin Advanced Fiber Co., Ltd. production METAMAX (Metas) fiber, the use of international advanced standards, with the introduction of advanced equipment manufacturing and production of the US-resistant high-temperature needle punching filter felt. Note: 1, the United States Tatas high temperature needle felt filter performance test table see Table 2, the United States DuPont produced DuPont Nomex (NOMEX) and Japan Teijin produced Conex (CONEX) Collectively. 3, sewing the United States Tasi filter bag, you must use a dedicated sewing thread. I made the company METAMAX sewing thread, high strength, good wear resistance, temperature up to 260 or more.
