ABSTRACT:
A reverse pulse cleaning system for use in a bag house filter including a blow tube (2) having outlet holes (3) to direct high velocity air pulses into filter bags to be cleaned. The systems includes a nozzle (1) having a control formation between the inlet and outlet ends of the nozzle. The control formation determines air flow characteristics such as velocity and direction of flow emerging from the outlet holes (3) and can improve uniformity and effectiveness of filter bag cleaning. A clampable and releasable fixing of the nozzle (1) to the blow tube allows replacement of the control formation with one of different characteristics during manufacturing or insitu fine tuning. The fixing allows the precise alignment of nozzles (1) on assembly which reduces the need for costly precision in forming the blow tube outlet holes (3). The system may include a tube (9) forming part of the nozzle with adjustable radial holes (13) to induce secondary air into the cleaning flow and may include a venturi (10) to induce tertiary air.
