Technical Paper: Improving The Cleaning Cycle In Baghouse Collectors

By Brian Mathews and Glenn Bitner, Scientific Dust Collectors

The dust collector has been around for many years. The generic pulse jet baghouse in particular has been around since 1963 and the cleaning cycle has not changed much in over 45 years. The cleaning cycle is the most important part of the dust collector. In a generic baghouse, an orifice and venturi system are used to induce air; whereas Scientific Dust Collectors uses a converging/diverging nozzle developed in the late 1970's. The converging/diverging nozzle allows for more cleaning air to be induced into the bag compared to the generic orifice and venturi system. It is because of this that Scientific Dust Collectors can operate at higher air-to-cloth ratios, clean more of the filter bag, and provide longer filter life.
