Relationship between drying temperature and sludge treatment capacity of sludge dryer

Sludge dryer has a wide range of applications, which can be used to dry municipal sludge, electroplating sludge, chemical sludge, steel mill sludge, papermaking sludge, textile sludge, printing and dyeing sludge, pharmaceutical sludge, tanning sludge and so on. Especially, it has a good drying effect on high humidity and high viscosity sludge, so it is loved by users.

To improve the sludge treatment capacity means to improve the efficiency of sludge dryer. There are many factors affecting the efficiency of sludge dryer, such as sludge characteristics (water content, viscosity, particle size), feeding speed, drying temperature and air volume. Today, we focus on the relationship between drying temperature and sludge treatment capacity.

Sludge dryer mainly through heat transfer, so as to evaporate the internal moisture of sludge. Increasing the drying temperature of the equipment can quickly realize sludge dewatering and drying. At the same time, under the action of the crushing device installed inside the equipment, the sludge can be quickly separated, dispersed and stirred to speed up the contact between the sludge and the hot air, which can not only improve the utilization rate of heat energy, but also improve the sludge drying efficiency; the barrel of the equipment has a good temperature retention performance, reducing the heat loss inside the equipment; The equipment adopts hot air distribution system, which can adjust the drying temperature and air volume according to the moisture content of sludge in different drying stages, so as to ensure the quality of sludge products after drying.

However, the drying temperature of the sludge dryer also has a certain range, so it can't improve the drying temperature of the sludge blindly, which will not only affect the quality of the finished product after the sludge drying, but also easily cause the hidden danger of the equipment safety. Because of the characteristics of some sludge, the drying temperature can not exceed a certain limit. Once the drying temperature exceeds a certain limit, physical or chemical reactions will occur in the sludge, which will change the original organizational structure of the sludge and reduce the quality of the dried sludge. Therefore, the sludge dryer from the design, construction, production and other aspects, need to do a good job in fire and explosion-proof measures, so as to prevent. Do not blindly pursue work efficiency and forced to increase the drying temperature, so the gain is not worth the loss.

In a word, the temperature of the sludge dryer is set before the equipment leaves the factory. If there are no other problems, the user should try to reduce the adjustment of the drying temperature. If necessary, you can seek the help of the manufacturer, so as not to affect the operation and treatment capacity of the sludge dryer.
