Analysis of the reason why the desiccant dryer can not dry materials normally
Analysis of the reason why the desiccant dryer can not dry the materials normally, is now widely used with engineering plastics. Dehumidifying dryers have gradually replaced traditional hot air dryers and are widely used in industrial production. The use of dehumidification dryers can be divided into stand-alone and centralized. Stand-alone dehumidification dryers generally include a dryer host, a dehumidifying dryer barrel, and a suction machine. The single-machine application is suitable for a small number of various types of drying, and its advantages are good drying efficiency and convenient and quick reloading.
The reasons why the desiccant dryer cannot dry materials normally are as follows:
1. The waste heat flue gas whose temperature is less than 350℃ can not be used as the heat source to dry materials.
2. It is impossible to deal with the phenomenon that the material bonding particle size becomes larger during the drying process, which greatly affects the material effect.
3. The problems of large heat loss, low thermal efficiency, high coal consumption, difficult control of the discharge moisture, and low relative output are common.
4. The dehumidifier dryer does not use an automatic microcomputer detection and control system, and cannot accurately detect and control materials, wind, coal, etc. on-line, resulting in the failure of the drying system.
5. It can't adapt to the drying of materials containing crystal water, and can't adapt to the drying of materials with high moisture content.
