Rolling Mill Fume Exhaust PPS/DBF

High Efficiency to Meet Stringent Regulations

The CECO Busch PPS/DBF were developed specifically to meet the increasingly stringent PM 2.5 environmental regulations and opacity control. PPS/DBF systems are especially well suited for Sendzimir-type Rolling Mill/Steel Cold Rolling Mills applications.

The quantity and particle size of liquid mist generated from rolling mills are a function of many variables, including coolant type, coolant flow rate, metal temperature, strip speeds, and saturation dew point. Rolling Mills have several mist generation mechanisms such as hydraulic pressure sprays and surface boiling followed by condensation. For this reason, the size and character of liquid particulate vary regularly.

A multiplicity of coolants and rolling methods mandate the use of multiple stages to achieve the lowest maintenance and highest possible collection efficiency. The PPS/DBF unit employs cleanable media, disposable media, or a combination of both. The PPS/DBF system is primarily used in Sendzimir Rolling Mill applications.

The PPS/DBF eliminator mechanically removes and drains liquid particulate using several mechanisms. Mists are removed by inertial impaction, direct interception, and Brownian capture depending on the droplet diameter and liquid density. The PPS/DBF unit provides removal of liquid particulate down to 0.3 microns.  The PPS/DBF mist eliminator offers maximum collection efficiency and the lowest opacity.
