Medium temperature dust bag

Usage Introduction


Medium temperature dust baginthe flue gas temperature is higher occasions, smelters, carbon black plants, iron plant blast furnace gas, calcium carbide plant kiln exhaust gas, casting, steel plant flue gas, cement plant kiln exhaust gas, asphalt concrete mixing asphalt flue gas, coal-fired boilers and other high temperature environment of dust removal and purification, it is not competent.

1. These dust-containing smoke and dust are not suitable for collection by bag dust collector due to specific resistance limitation, and can only be collected by dust bag or other means;
2. If it is necessary to reduce the temperature of dust-containing flue gas below 150 ℃, the investment is high or limited by the site;
3. Because the dust-containing flue gas contains sulfur components, the dust-containing flue gas has an acid "dew point" and can only be above the acid dew point, that is, under the condition of higher temperature.
4, filtration and separation and other factors, so it is necessary to have a kind of chemical fiber that can withstand higher temperature to make filter material.

Specific Features


medium temperature dust bag is characterized by good heat resistance and flame retardant, infusibility. Fiber oxygen index can be 29%, not spontaneous combustion. When the temperature is above 400 ℃, the fiber is slowly carbonized. In addition, the Metas fiber also has good dimensional stability.

medium temperature dust bag made of imported raw materials, its material characteristics:
1. Excellent temperature resistance: continuous operation at a temperature of 204 ℃ (instantaneous temperature of 250 ℃), and can withstand repeated fluctuations in temperature at 250 ℃.
2, outstanding dimensional stability: at a temperature of 250 ℃ only less than 1% of the thermal shrinkage, with excellent high temperature stability.
3, proud of the fire: at 400 ℃ began to decompose and carbonization, the limit oxygen index (LOI) is 30, not spontaneous combustion or combustion.
4, good chemical resistance: low concentration of acid and alkali and most hydrocarbons will not affect it, even a small amount of fluoride will not be significantly corroded; it is one of the ideal accessories for asphalt concrete mixing plant.
