Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of defluorination agent production, in particular to a drying device for medicine production. Background Art
[0002] Modified lignin-based defluoridation agent is a new type of adsorbent obtained by chemically modifying lignin. Lignin is widely present in plants and is an aromatic polymer compound with abundant reserves in nature. Through modification, lignin can enhance its adsorption performance, especially in removing fluoride ions from water.
[0003] In actual production, lignin needs to be repeatedly soaked and dried, and reacted in a quartz tube reactor. In the processing process of existing equipment, the temperature of the quartz tube reactor is often 400-600℃, the temperature of the drum drying oven is 100-120℃, and the temperature of the washing tank and the iron sulfate soaking tank are both at room temperature. If the hot air from the quartz tube reactor is directly used in the drum drying oven, the microstructure of lignin will often be damaged due to excessive temperature, thus affecting product performance; and after the quartz tube reactor is processed, washing directly in the washing tank will also cause a large temperature difference, which will not only cause a decline in product performance, but also waste a lot of energy.
