ABSTRACT:
An emissions control system and method are provided for controlling the particulate matter within the fiber-containing airflow discharging from a fiber processing plant, such as a cotton gin. The system includes an upstream housing defining a settling chamber therewithin which communicates with at least one conduit used to discharge a fiber-containing airflow from the fiber processing plant. The system further includes a downstream housing defining a filtering chamber therewithin which communicates with the settling chamber. A porous, bag-type filter is disposed within the filtering chamber and includes an opening in communication with the settling chamber. A forward end of the filter, which includes the inlet opening, is disposed in sealing engagement with a wall separating the settling and filtering chambers so that substantially all of the fiber-containing airflow which enters the settling chamber is forced to flow through the filter. The airflow then discharges from the filtering chamber through a discharge port formed in a floor of the downstream housing. The porous, bag-type filter is made of a fabric material having a mesh size and surface area which are selected to control the particulate matter within the fiber-containing airflow to an acceptable level as it discharges from the filtering chamber.
