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.
