Cattin Filtration - Sleeves filter (ATEX)

- The treatment of wood dusts

- The treatment of food dust

- Processing of metal chips

The air carrying the dust enters the filter through the tangential inlet positioned in the cyclone pre-separation zone.

Large dust particles then fall into the cone.

This dust is discharged through an air lock is evacuated directly in a leaktight storage, placed under the filter cone.

Fine dust go back and are retained by the filter bags.

The accumulation of dust on the sleeves causes clogging. The handles of the regeneration system is located in the cap: injecting compressed air against the current in the sleeves. The cleaning system, consisting of a reservoir and pneumo valves, injects air in manifold modules

Dust treated in the filtrationmay be combustible. Thus may explode in the presence of a heat source.

The consequences of an explosion can be:

 exotherm and dust

 fire with flames

 pressure wave

To protect the unit against the violent pressures, we have established tear membranes, called explosion vents according to the following data:

 model: 410x410 or 666x1000

 Kst dust: According enforcement

 vent Pstat: 0.1 bar +/- 25%

 vent area per 0.5 m² or 0.165 m²
