Dust collector system
Dust collection involves the removal or collection of solid particles from a flowing air stream to eliminate nuisance dust for safety and health considerations. Even installing a dust control system does not promise complete prevention of dust emission but a well-designed system can protect and gets other benefits such as preventing or reducing the risk of a dust explosion or fire, reducing the likelihood of accidents, reducing cleanup and maintenance costs, reducing equipment wear and assuring continuous compliance with existing health regulations.
Dust collection systems use ventilation principles to capture the dust-filled airstream and carry it away from the source through ductwork to the collector. The selection of a dust control system is based on the desired air quality and existing regulations. Dust collection systems can provide reliable and efficient control over a long period. The dust collection system also is known as the local exhaust ventilation system is one of the most effective ways to reduce dust emissions.
A typical dust collection system consists of four following components:
• An exhaust hood to capture dust emissions at the source.
• Ductwork to transport the dust to a dust collector.
• A dust collector to remove the dust from the air.
• A fan and motor to provide the necessary exhaust volume and energy.
The dust collector performance can either make or break the entire dust collection system. On one hand, a properly performing dust collector will efficiently filter the particles from the airstream, clean itself, discharge the solids into a hopper, and allow proper airflow through its filter media, thereby maintaining proper conveying velocities in the system and stable fan
operation. On the other hand, poor dust collector performance can allow particles to bypass
through the filter, clogging and plugging, and substantially reduced airflow, rendering dust pickup and conveying ineffective
