The aramid(Nomex) filter bag can be used in the tail of the cement kiln?

 

Can the aramid filter bag be used in the tail of the cement kiln? The answer is yes. aramid fiber can be used to purify the flue gas of cement kiln from the aspects of temperature, strength, chemical resistance and flame retardance. And aramid(NOMEX) filter nags can be used in cement kiln tail.

 

The bag type dust collector can achieve better dust removal effect in the application of the cement kiln head and the tail gas dust of the kiln. It has become a necessary production equipment for the cement production enterprises.

However, there are often problems in the operation of bag filter, and more than 50% of the problems are related to the selection of filter material. When the flue gas temperature is high, the filter bag will be destroyed and condensation will occur when the temperature is low. In serious cases, the dust collector may even be invalidated. Selecting suitable filter material is of great significance for improving the usage of bag filter in cement kiln.

The full name of aramid is "aromatic polyamide fiber". It is a new type of synthetic fiber. Aramid has good mechanical properties, high strength, high strength and high toughness. The elongation of aramid fiber is large and the feeling of hand is soft. The aramid fiber is with high temperature resistance, acid and alkali resistance and good insulation. It has excellent aging resistance and long life cycle.

The thermal stability of aramid fiber is excellent. It can be used continuously below 205 degrees centigrade, and it can still maintain higher strength at 250 degree Celsius. It is a good material for treating high temperature gas at 180 -220 C.

Can the aramid filter bag be used in the tail of the cement kiln? The answer is yes.

As one dust filter bag manufacturer, SIIC team from INDRO filtration now analyze and explain the characteristics of the flue gas at the end of the cement kiln as followings:

The flue gas temperature at the end of the cement kiln is below 250. The main components are SO2, NOx, O2, N2, CO2 and water. The main components of the dust are SiO2, Al2O3, Fe2O3, CaO, MgO and so on. The flue gas of cement kiln tail has large volume of smoke, high temperature, high dust concentration, fine and sticky dust, and containing corrosive flue gas. To sum up, aramid fiber can be used to purify the flue gas of cement kiln from the aspects of temperature, strength, chemical resistance and flame retardance. And aramid(NOMEX) filter nags can be used in cement kiln tail.
