AI Technical Summary
Existing indirect heating methods suffer from heat loss and low heating efficiency, especially in applications requiring high material purity, where traditional indirect heating methods result in low heating efficiency.
The material direct injection heating device is adopted. The material enters the mixing chamber in a high-pressure dispersed state through the feeding component. The heating component provides steam and the steam is pressurized in multiple stages by the pressurizing component to make the material and steam evenly mixed. The conical cylinder of the pressurizing component performs secondary compression of the steam to improve the steam injection speed and pressure. The bypass component is used to regulate the steam flow and control the temperature.
It improves the quality and efficiency of material heating, avoids the heat loss and structural complexity problems of indirect heating, and achieves efficient and uniform heating effect.
