Southern Field—Environmental Elements offers a wide range of fabric filter systems designed to control particulate emissions in a variety of utility and industrial applications. With the fabric filter, a particulate laden gas stream passes through the filter bag so that the particulate is collected on the surface of the fabric. Fabric filters are high efficiency collection devices capable of collecting fine particulate from the gas stream. Typical collection efficiencies exceed 99.9%. Southern Field—Environmental Elements offers both Pulse-Jet and Reverse Air Fabric Filter Systems.
PULSE-JET FABRIC FILTERS
The Southern Field—Environmental Elements Pulse-Jet Fabric Filter System consists of individual fabric filter modules, each containing up to 720 filter bags each 6 inches in diameter and ranging in length from 10 to 28 feet. With pulse-jet filters, gas flows from the outside to the inside of the bags. The bags are mounted on cages to keep them from collapsing from the force of the flue gas. Dirty gas enters the patented Stepped Inlet Manifold and is uniformly distributed among the modules. Gas enters each module through a vaned inlet elbow near the top of the hopper where a patented Inlet Vane System uniformly turns and distributes the gas flow upward, depositing the dust on the exterior surface of the bags. Clean gas passes through the fabric and into the outlet manifold through air-operated poppet dampers. Periodically the fabric is cleaned by a pulse of compressed air injected into each filter bag through a venturi nozzle. Pulse cleaning dislodges the dust cake collected on the outside of the bag and allows it to fall into the hopper for evacuation. Cleaning can be performed either on-line or off-line depending upon customer preference, bag life issues, or emission performance requirements.
The results of these proprietary systems are uniform distribution of gas and dust and reduced mechanical pressure drop… the secret to LONG bag life.
