DENA GIMS T ATEX / DEDUST T ATEX

The DEDUST-ATEX model bag filter, designed for heavy-duty use, functions as an independent dust filtration system, featuring automatic cleaning with compressed air, specifically for filtering and separating medium, fine, and ultra-fine dust particles. The automatic compressed air jet cleaning mechanism helps maintain nearly constant pressure drops. This filter is safeguarded with a venting system tailored to the properties of the dust and the installation site of the equipment. This type of filter, when paired with specialized compartmentalization systems, helps prevent explosions in the filter and piping.

Description

Operational Principle

In the DEDUST bag filter, the contaminated air flows directly into the dust collection hopper. Through a combination of reduced air velocity and flow distribution, some dust settles directly in the hopper, while the rest accumulates on the outer surface of the filter elements. The highly permeable material of the filter bags enables gas to pass through while trapping dust, forming the primary filtration layer (the "cake"). Proper removal of this "cake" is crucial for ensuring optimal filtration efficiency and minimal pressure drops; this equilibrium is achieved via the DENA PULS-JET system. A burst of compressed air, stored in a dedicated tank, is cyclically injected into the sleeves, generating a powerful counter-current shaking wave that dislodges and drops the particles adhered to the outer wall of the sleeves.
