AI Technical Summary
In existing technologies, the high-temperature exhaust gas treatment of fertilizer granulation dryers suffers from problems such as low thermal energy utilization efficiency, serious energy waste, low resource recycling rate, bottlenecks in dust removal and cooling efficiency, and serious raw material loss.
A steam condensation waste heat recovery device based on phase change medium circulation is adopted, including a cascade heat exchange module, a closed-loop circulation module and an intelligent control unit. Through the combined design of cyclone dust collector, tubular heat exchanger, venturi tube and scrubbing tower, the cascade utilization of waste gas heat and the resource recycling of wastewater are realized, combined with the treatment of the collection tank with temperature and pH adjustment.
It improved the overall heat recovery rate, reduced the workload of the scrubbing tower, increased the raw material recovery rate, reduced energy consumption and wastewater discharge, and achieved efficient energy-saving treatment of waste gas and effective utilization of resources.
