RfP Fabric Filter Technology
RAGAR AG / DAIGE EP have developed its own bag house technology. It provides high cleaning efficiency with reduced cleaning cycles and low fabric bag stress. The overall design is focused on low pressure drop, low power consumption (save compressed air), high efficiency (dust emission < 15 mg/Nm3), high availability and long service life. A lifetime for the fabric of more than 5 years can be guaranteed.
The abbreviation RfP stands for Reverse flow Pulse which describes the function principle as follows in four steps: First a small part of fabrics (<10%) is separated form cleaning operation. Second the reverse gas flow pre-cleans the fabrics. Third a short, low pressure jet pulse finally cleans the fabric. Fourth the cleaned fabrics wait to be put back into cleaning operation.
Thus the RfP principle combines the advantages of the reverse flow cleaning technology and the jet-pulse cleaning technology and eliminated their disadvantages at the same time.
The advantages are low power demand, low filter stress (revers flow technology) and small filtration area (jet-pulse technology).
Due to the higher cleaning efficiency and the lower pressure loss, compared with other technologies with the same gas to cloth ratio (G/C), the RfP technology reduces the operational costs by ~ 30%
RAGAR AG / DAIGE EP ESP
RAGAR AG / DAIGE EP have the special know-how on high dust ESP technology. Through the calculation of the required surface area, type selection of discharge and collecting electrode and especially because of the structure design of gas-powder uniformity and gas distribution at the inlet-hood of the ESP.
The RAGAR AG / DAIGE EP ESP design has been proven to provide much higher efficiency than conventional ESP designs.
Therefore, in case the efficiency of an existing system is not good or the emission requirements got toughen, our design can avoid changing the precipitator technology or increasing the collection area.
Thus, in many cases, it is not necessary to bear high costs to reach higher efficiency of the ESP.
By applying the RAGAR AG / DAIGE EP design, the dust emissions can be reduced by 50% of the previous situation.
