Pulse Jet Collectors
Pulse jet baghouse dust collectors are used when it is impractical to shut down your dust collector to clean the bags. A pulse of compressed air is blasted through the bags to blow loose the built up particles on the bags to maintain optimum filtration efficiency.
A pulse jet dust collector is a dry filtration system that incorporates an integral media cleaning system. It might be called a pulse-jet collector, a pulse-jet filter or a pulse-jet fabric filter. The media is usually a tubular shaped vertical bag of varying diameter and length. It’s also common to see pleated bags and “flat” bags mounted horizontally. Many bags are arranged inside a housing and particulate matter accumulates on the outside of the bags.
The cleaning system removes particulate that has accumulated into a “cake” onto the bags by blowing high pressure compressed air into the inside of the bag. Nederman MikroPul is proud to be the home of the original Pulse-jet cleaning patent, granted in 1957.
Pulse jet bag filters are a common type of dry air pollution control equipment found in industrial plants and play a critical role in the protection of workers, the general environment and also to collect valuable material for refining or re-use.
Automated cleaning control systems have become common to regulate the pulse of compressed air that the bags receive. Cleaning strategy and correct operation of the cleaning system yields improvements in the use of compressed air and therefore energy use. Bag life has been shown to improve through good maintenance practices in pulse-jet dust collectors.
