Discussion on drying time, efficiency and energy consumption of sludge dryer

The drying process of the sludge dryer is to evaporate the water in the sludge through the heat energy, so as to achieve the drying effect. In this process, sludge drying needs a lot of energy. Then there are many users and more concerned about the treatment capacity, drying cost and drying efficiency of sludge dryer. Now I will discuss the drying time, efficiency and energy consumption of sludge dryer with you.

For the same specification and model of sludge dryer, to improve its production efficiency, it is necessary to shorten the drying time of sludge. Can use 5 minutes to dry sludge, no one will choose to use 10 minutes. Then there are many factors that affect the drying of sludge, such as the characteristics of sludge (moisture content, particle size, viscosity, water molecular structure, hygroscopicity, etc.), drying medium (temperature, wind speed), etc., which together determine the drying time. At the same temperature and wind speed, the lower the moisture content and viscosity of sludge, the higher the drying efficiency. When drying the same kind of sludge, by reducing the drying temperature and increasing the drying wind speed, the drying efficiency can also be improved and the energy consumption can also be reduced.

The drying process of Jiaozuo ZJN sludge dryer is designed and developed on the premise of these factors. In the whole drying process, the air volume and temperature of the hot air are adjusted with the change of sludge moisture content. At the same time, the technology of "low temperature and large air volume" is used to make the sludge in an ideal drying environment, so as to effectively shorten the drying time and reduce the production cost. The equipment supports a variety of heat sources, such as coal, oil, gas, biomass fuel and the waste heat of the boiler of the enterprise. Specific or need to choose according to the needs of users.
