20 Economical Ways to Improve the Performance of a Baghouse Dust Collector

摘要

The baghouse dust collector is an integral component to many industrial processes. However, many baghouses in operation do not offer adequate technology to accommodate today's aggressive production demands. Thus, plant operators and owners are faced with one of three possible decisions concerning their inefficient baghouse:(1) allow the baghouse to continue operating without modifications;(2) buy a new baghouse or upgrade the baghouse to a new to a more efficient design, such as a pulse-jet, that can take advantage of high efficiency pleated filter elements instead of filter bags and cages; or (3) make minor modifications and/or employ modestly-priced devices and tools to improve the operation of the existing baghouse. This paper will focus on #3 and outline many cost- effective ways that can have an immediate impact on overall performance, without the need for a full rebuild of the baghouse.Some of these solutions revolve around the mechanicarparts of the baghouse, suggesting ways to improve performance of the existing design, or upgrading to newer technology. Topics for discussion will include ductwork configuration, rotary valve operation, and -participate buildup in hoppers. Each of these areas can inhibit overall dust collection effectiveness and must be addressed so that other modifications to the baghouse will have maximum benefit. The paper will also discuss upgrading to higher performance accessory items such as pleated filter elements, fabric finishes, and door seal. These inexpensive devices are offered in many styles to fit a variety of OEM designs and are engineered to overcome original design flaws that lead to short bag life, improper filtering/cleaning, and emissions. Included in these suggestions are tips for correct filter bag installation in various styles of baghouses. These and other ideas are presented to provide a baghouse owner a full range of options in which to enhance dust collection performance. Understanding these options, along with the benefits each offers in terms of time savings, reduced energy consumption, and filtration enhancement, can enable a decision maker to discover solutions that provide maximum impact at minimal cost.
