Fabric filters are an alternative to dry type electrostatic precipitators and are suitable primarily for dry dust. Adressing individual operating conditions:
Depending on the application, round, in-line or chamber filters are used.
The units are equiped with:
Support fabric and needled felt quality are specified depending on emissions and operating temperatures
Compressed-air jet pulse, on-/offl-ine
Moving mean pressure, off-line
Moving compressed air, offline
Dry sorption by the LÜHR conditioning rotor-recycle process
By adding and/or activated calcium hydroxide Ca(OH)2 charcoal into the crude gas stream, gaseous emissions, for such as example HF, HCI, SOx, Hg as well as PCDD/PCDF, can be bound to the adsorbing agent and then collected in the following bag filter. The conditioning rotor-recycle process has proved to be as a reliable system with a high over-all efficiency.
