The differences between diagonally inserted and vertically mounted cartridge dust collectors

Diagonally inserted dust collectors adopt a downward-flow design, with air entering from the top and exiting from the bottom. 

During pulse backwashing, dust stripped from the filter cartridge surface falls by gravity, and its falling direction aligns

 with the inlet air flow—greatly facilitating dust settlement. For vertically mounted models, air enters from the bottom (or side), 

and dust falls opposite to the air flow. This easily causes secondary dust emission in the hopper, hindering smooth dust settlement.

Diagonally inserted units use compressed air to shake off dust on filter cartridge surfaces for cleaning. 

Vertically mounted ones, however, inevitably generate secondary dust emission due to the conflicting directions of dust fall and air flow. 

This re-entrained dust reattaches to filter cartridges, leading to incomplete cleaning, high operating pressure difference,

 increased energy consumption and shorter filter cartridge service life.

Diagonally inserted dust collectors resolve the secondary dust emission issue. Their design uses one valve to backwash two filter cartridges, 

while vertically mounted models use one valve for multiple filter cartridge groups. 

Clearly, the one-valve-per-group design cleans filter cartridge surfaces more effectively, extending their service life.

Replacing filter cartridges of diagonally inserted models requires no special tools and can be done by a single worker.

For vertically mounted units, workers must open the top access door, fully exposing the dirty air chamber. 

Dust tends to spread widely during filter cartridge replacement, leaving the maintenance area messy. 

The process is time-consuming and operator-unfriendly; some models even require workers to enter the dirty air chamber for filter cartridge replacement. 

Additionally, the large access door demands stricter sealing standards.
