The main working principle: the hot flue gas stove to be 800-950 ℃ high-temperature jet pipe heat exchanger, a turbulator heat exchanger, low temperature heat pipe heat exchanger three levels of heat, the temperature dropped to 140-160 ℃ emissions. The cold air from 20 ℃ by three stage heat exchanger and heat of flue gas countercurrent heat exchanger, the final was heated to 550 ℃, applied to the back section of drying.
The main characteristic of the equipment:
1, with coal as the fuel, high heat efficiency reaches more than 70;
2, high safety and reliability, simple operation and maintenance and low cost;
3, long operating life, up to 8 years;
4, the heating temperature is high and stable, the temperature is 550 ± 3 ℃;
5, dust emissions to achieve national environmental standards.
