Baghouse Dust Collectors

Vacuum is created by the centrifugal blower with suitable airflow and static pressure. The suction created by the blower passes through filtration system and ducts and it reaches the pick- up hood placed near the dust emission area. Pick up hoods are designed in such a way to capture maximum amount of fly dust. The placement of hood and size of the hood defines the amount of dust captured. The dust once captured is conveyed through the ducts which leads to the filtration unit. In the filtration unit the primary filtration is done by the baffle plate and the larger dust particles are filtered in this area, air + minute dust particles passes through the bottom of the tubular bag filters and the dust particles get settled over the outer surface of the filters. 

Since the filtration of dust is done continuously, the filters are cleaned in regular intervals by the reverse pulse jet unit to prevent choking of filters. Dusts gets settled in the hopper and it is transferred to the dust collection box or tank through rotary air lock valve. Rotary air lock valves prevent dust escape from collection tank back into the filtration unit. The pressure above the filtration unit and inside the filtration unit is monitored continuously to check for dust bag choking. Clean air is exhausted through silencer and chimneys into the environment at required heights.


The air-to-cloth ratio is the most important criteria for baghouse filter design. It is calculated by dividing the amount of air entering by the total surface area of the filter. This ratio determines the volume of airflow through the dust collector. An optimal air to cloth ratio needs to be determined to find a balance between the size of the dust collector (capital costs) with the pressure drop (operating costs). 


The differential pressure is a measure of the resistance to airflow in the system. Baghouse filter dust collectors with a larger pressure drop require higher-powered fans to move air through the system, resulting in increased energy costs. 

Determining the filter material is an important part of baghouse design, as it determines the life and effectiveness of the filter bag. The type of fabric used depends on many factors including the volume of dust, the size of dust, moisture content etc.
