AI Technical Summary
The flue gas discharged after being treated by a wet electrostatic precipitator in a boiler contains a large amount of moisture and high temperature, which leads to water waste and white fog phenomenon, violating the concept of energy conservation and environmental protection.
The system employs an air-cooled plate heat exchanger and a condenser shell structure. The treated flue gas is introduced into the air-cooled plate heat exchanger for condensation, and the condensate is collected and recycled. Combined with the exhaust gas fan and heat exchange fan, dehumidification and dust removal are achieved, preventing the generation of white mist.
It achieves efficient recovery and utilization of moisture in flue gas, avoids white fog phenomenon, improves purification treatment level, saves water resources and ensures clean exhaust gas emissions.
