Method for promoting light calcium carbonate digestion process by increasing digestion temperature through photo-thermal technology
The invention provides a method for promoting a light calcium carbonate digestion process by increasing digestion temperature by using a photo-thermal technology, and belongs to the technical field of photo-thermal utilization, a digestion kiln is set as a solar vacuum heat collection tube device, lime and digestion water enter the solar vacuum heat collection tube device at the same time, the operation temperature is 100-400 DEG C, and the digestion water is in a water vapor state. The digestion water is higher in temperature, the physical form tends to be in a gaseous state, the effect is better when the digestion water makes contact with lime for digestion, the internal temperature of the adopted heat preservation device is more stable, and the quality of the digested cooked pulp cannot be changed due to temperature change. Meanwhile, heat loss caused by temperature difference inside and outside the digestion kiln is reduced.
本发明提供一种利用光热技术提高消化温度促进轻钙消化过程的方法，属于光热利用技术领域，将消化窑设置为太阳能真空集热管装置，将石灰和消化用水同时进入太阳能真空集热管装置，运行温度在100‑400℃，消化用水为水蒸气状态。本发明消化用水温度更高，物理形态更趋向于气态，与石灰接触消化时效果更好，采用的保温装置内部温度更稳定，消化后的熟浆不会因温度改变造成质量变化。同时，减少消化窑内外温差导致的热量损失。
