AI Technical Summary
In the production of compound fertilizer, the dust and airflow generated during the drying process cause air pollution and waste of raw materials. Existing dust removal equipment is prone to clogging and suffers from serious heat loss, making it impossible to efficiently recover dust.
A dust recovery mechanism is designed, which uses U-shaped partitions, air duct partitions and intermediate partitions to separate the main chamber. A multi-hole cylinder rotary washing system composed of heaters, spray heads and filters is used to achieve dust washing, capture and recovery, and heat loss is reduced through an insulated chamber.
It achieves efficient dust recovery and effective utilization of heat energy, reduces equipment footprint and heat loss, improves heat energy utilization efficiency and waste heat utilization rate, and simplifies the handling and operation safety of heavy components.
