Dry, visible, salt-dust filtration of the face exhaust air at the WIPP

摘要

To improve underground safety and visibility during mining applications, the Waste Isolation Pilot Plant designed and built a dry-dust filtration unit. The unit works in conjunction with a Spendrup 1120-70 fan with ventilation tubing to filter the face exhaust air during mining operations. The closed- loop system is designed to filter 17 m~3/s (36,000 cfm) and is intended to screen 10-#mu#m (1,250 mesh) and larger particles at 90 percent efficiency. To accomplish this, the unit uses a combination of Dollinger Staynew Inertial Spin-filters, cyclones and traditional mesh filter media.
