Description

Technical Field

[0001] The utility model relates to the technical field of filter cartridge dust collectors, and in particular to a multi-stage combined pulse filter cartridge dust collector. Background Art

[0002] The cartridge dust collector is a dust collector that uses cartridges as filter elements or pulse jets. It is used in factories or places where dust is too much. In actual use, in order to meet the filtering requirements of different places of use, multiple groups of pulse cartridge dust collectors will be installed in combination. The so-called combination is to connect multiple pulse cartridge dust collection units in series according to the requirements of the processing volume. The existing cartridge dust collector mainly includes a box, a pulse jet system, a bracket and an ash hopper. The ash hopper is connected and installed at the bottom of the box. The bracket supports the assembled box. Many jacks are set at the front end of the box for inserting filter cartridges to facilitate replacement. The pulse jet system is installed on the rear side of the box, and the nozzle of the pulse jet system is passed through the rear side wall of the box and inserted into the rear side of the corresponding filter cartridge for backblowing and cleaning the filter cartridge. An air inlet pipe is set on the ash hopper to pass dust-containing gas, and an exhaust pipe is set on the top of the box to discharge the purified gas.

[0003] By adopting filter cartridges, compared with filter bags, it has the characteristics of high filtration accuracy and small footprint. It can filter special dust and greatly improve the effective filtration area. The filter cartridge elements are small and easy to install, and are suitable for use in industries with high dust concentrations. Although the filter cartridge dust collector has the above advantages, the filter cartridges in the existing filter cartridge dust collectors are basically arranged in a horizontal insertion manner. Although there are multiple layers, they are all straight up and down designs. When the filter cartridge is backblown, the dust on the outside of the upper filter cartridge falls downward and happens to fall on the outer surface of the lower filter cartridge. Due to the horizontal arrangement of the filter cartridge, the dust on the upper side of the filter cartridge itself is more difficult to be completely cleaned than the dust on the lower side, which shortens the service life of the filter cartridge inside the dust collector as a whole and affects the filtration effect. Utility Model Content
