DENA GIC-ATEX/GIM ATEX Blast Panel

The GI-ATEX model bag filter functions as a self-sufficient dust filtration system. It features an automatic cleaning mechanism utilizing compressed air, specifically designed for filtering and separating medium, fine, and ultra-fine dust particles. The automatic cleaning system, which employs compressed air jets, helps to maintain nearly constant pressure drops. The filter is safeguarded by a venting mechanism that is tailored to the nature of the dust and the environment in which the equipment is installed. This kind of filter, when combined with specialized compartmentalization systems, helps to prevent explosions within the filter and its associated pipes.

Description

Operational Principle

In the GI-ATEX bag filter, the contaminated air enters directly into the dust collection hopper. Due to the synergistic effect of reduced air speed and flow distribution, some of the dust settles directly into the hopper, while the rest accumulates on the outer surface of the filter elements.

The highly permeable material used for the filter bags allows gases to pass through, yet it retains dust particles, forming the filter's primary filtration layer. Proper removal is crucial to ensure optimal filtration efficiency and minimal pressure drops. This balance is achieved using the DENA PULS-JET system. A jet of compressed air, stored in a dedicated tank, is injected cyclically into the sleeves, generating a powerful counter-current shaking wave that effectively dislodges and forces down the particles that have settled on the sleeves' exterior.

Construction Details

The bag filter is constructed from heavy-duty galvanized sheet metal and includes support legs, inspection doors, and a dust collection hopper.
