Food Factory Biomass Boiler Dust Collector Equipment

    Specifications for small biomass boiler dust collectors in food factories, 1-ton, 2-ton, 4-ton, 8-ton, and 10-ton biomass boiler dust collectors all fall under the category of small boiler dust collectors. During the retrofitting of biomass boiler dust collector equipment in food factories, boiler dust collectors are mostly used for flue gas treatment in environments with dust concentrations not exceeding 25g/m3 and flue gas conditions at temperatures of 140~170°C, such as chain grate boilers, circulating fluidized bed boilers, etc.

    Food factory biomass boiler dust collectors typically use pulse baghouse dust collectors as flue gas purification equipment. The filter chamber can select different types of filter media based on the varying physical and chemical properties of the dust, such as PPS membrane filter media, Fluorite, etc.  The key design point for biomass boiler baghouse dust collectors is the selection of the filtration velocity for the boiler baghouse dust collector.

      When designing food factory biomass boiler baghouse dust collectors, it is essential to ensure that the filtration velocity of the baghouse dust collector does not exceed 0.8 m/h. The compartmentalized stop-air pulse jet cleaning technology is adopted, and a secondary combined dust collector unit with a cyclone dust collector and an active capture device installed in front of the baghouse dust collector is used. This two-stage flue gas treatment solution addresses the challenge of effectively treating biomass boiler flue gas.

      Food factory biomass boiler baghouse dust collector working principle:

      The dust-laden gas generated by boiler fuel combustion enters the hopper of each unit through the guide pipe. Under the guidance of the hopper flow system, large dust particles are separated and directly fall into the hopper, while the remaining fine dust particles enter the filtration zone of the middle chamber with the airflow. After filtration in the filter chamber, the clean gas passes through the filter bags, then exits through the upper chamber, lift valve, and exhaust pipe, achieving compliant emissions.
