CWMF’s Reverse-flow Baghouse
Hot-mix asphalt (HMA) producers seek the most efficient way to keep the environment clean and safe around their facilities. To assist in dust return as well as environmental excellence, the team at CWMF, Waite Park, Minnesota, developed the Dust-Eater Reverse-Flow Baghouse. Here’s how it works:
First, dryer exhaust gases and dust enter the baghouse through an inlet inertial separator and flow through distributor panels to be filtered through the dual-pocket, 14-ounce, Aramid bags.
For the cleaning process, open air rotors along the top of the baghouse allow air in to clean the bags by reversing the air flow through the bags within that specific cell of bags.
This causes dust cake to sluff off bags onto a sloped floor auger hopper where it augers to a discharge point.
Cleaned air enters the discharge plenum via air channels. Thus clean air exhaust gases exit the baghouse through the exhaust stack while collected dust fines are augured back to the drum or dust metering system for re-use.
