Contribution to Improvement of Cleaning Efficiency of Pulse-Jet Fabric Filters

Popis výsledku v původním jazyce

Uniform distribution of compressed air in a blow pipe is an important consideration in the efficient use of compressed air for pulse-jet cleaning of fabric filters. This paper reviews recent developments in this area. A formula for compressed air consumption per pressure pulse is derived, based on the pressure drop in the air vessel and polytropic change in the air state in the vessel during the pulse. A criterion for uniform distribution of compressed air in the blow tube is derived, based on the constant flow momentum of jets from nozzles in the blow pipe. A procedure for designing the diameter of the holes in the blow pipe is proposed. A simplified mathematical model for the distribution of compressed air in the blow tube is described. Very good agreement between calculated and measured values has been achieved.
