AI Technical Summary
Existing material drying equipment suffers from unstable output quality when faced with fluctuations in feed parameters, and the heat in the exhaust gas is not effectively utilized.
A continuous drying system was designed, including a material passage and a gas passage. A moisture monitoring device was set up to monitor the moisture content of the material in real time, and it was connected to a rotary valve, a regulating valve and a heater through a signal transmission device to realize the real-time adjustment of process parameters. At the same time, a heat recovery unit was used to recover the heat in the waste gas and reuse the energy through a shell and tube heat exchanger.
This improved the stability of material properties after drying and reduced production energy consumption through heat recovery, thereby increasing energy efficiency.
