Dust removal cloth bag of asphalt mixing plant

  Under the condition of normal flue gas temperature, the temperature resistance of bag filter bag is required to be below 150 ℃
However, in the occasions with high flue gas temperature, such as smelting plant, carbon black plant, blast furnace gas of ironmaking plant, kiln tail gas of calcium carbide plant, foundry, steel plant flue gas, shaft kiln tail gas of cement plant, asphalt concrete mixing asphalt flue gas, coal-fired boiler and other high-temperature environment, the bag filter is not competent for dust removal and purification
First, due to the limitation of specific resistance, these dusty flue gas dust is not suitable for electrostatic precipitator collection, and can only be collected by cloth bag or other methods; Second, if it is necessary to reduce the temperature of dusty flue gas below 150 ℃, the investment is high or limited by the site; Third, because the dust containing flue gas contains sulfur, the dust containing flue gas has acid & ldquo; Dew point;, Filtration and separation can only be carried out above the acid dew point, that is, under the condition of high temperature
In this way, a chemical fiber that can withstand high temperature is needed to make filter materials MetaMax fiber is an aromatic polyamide fiber
In addition to the spinnability and wear resistance of polyester fiber, its biggest feature is good heat resistance, flame resistance and non fusibility
Fiber oxygen index can be 29%, unnatural
When the temperature is above 400 ℃, the fiber carbonizes slowly
In addition, metas fiber also has good dimensional stability
Compared with glass fiber, its wear resistance and folding resistance are unmatched by glass fiber
Therefore, it has high temperature resistance and long service life
It is the preferred filter material for bag filter in high-temperature filtration occasions Our company selects Nomex produced by DuPont and conex high temperature resistant fiber of emperor, adopts international advanced standards, and develops and produces high temperature resistant needle punched filter felt with imported advanced equipment
