Pulse jet air cleaner systems; components; and, methods

摘要

Pulse jet air cleaner systems components and methods are described. The features relate to air cleaner housings that include a cartridge receiving section. Features described relate to a possible two-stage construction, a pulse jet accumulator section, pulse jet equipment for cleaning a filter cartridge positioned within the air cleaner; evacuation valve arrangements for projection of dust from the air cleaners; and other example features. Methods of assembly and use are also provided.

1. An air cleaner assembly comprising:
(a) a housing including an outer wall defining an air flow inlet; an air flow outlet and an interior;
(i) the housing outer wall including a sidewall having a dust evacuation aperture arrangement therethrough that has an aperture open area of at least 2 square inches;(ii) the housing having an end openable for service access to an internally received serviceable cartridge;(iii) the air flow outlet being an axial air flow outlet at an end of the housing opposite the end openable for service access; (b) a serviceable filter cartridge operably positioned in the interior of the housing;
(i) the filter cartridge being removable from the air cleaner housing; and,(ii) the filter cartridge comprising media surrounding an open, central, interior;(iii) the filter cartridge being positioned with an annulus between the cartridge and the housing sidewall; (c) a pulse jet distribution arrangement configured for operation during pulse jet operation to direct a pulse of compressed gas into the open, central, interior of the filter cartridge;
(i) the pulse jet distribution arrangement including a flow tube directed into the housing through the air flow outlet; (d) an evacuation arrangement configured to provide for ejection of dust from the annulus during pulse jet operation; and, (e) a flexible valve member positioned to flex open to provide dust evacuation flow from the air cleaner assembly, during pulse jet operation.
