The muddy material drying system developed by Zhengzhou Dingli Company is suitable for drying various sludges with high viscosity. It can dehydrate and dry wet sludge with a water content of about 85% into dry powder with a water content of less than 10%. The sludge drying system operates under negative pressure and is equipped with an enhanced heat transfer device for direct heat transfer. The drying moisture content of the material is easy to control, and the operation flexibility is large, allowing the product flow rate to have a large fluctuation range. In order to improve drying efficiency and reduce energy consumption, the sludge dryer also adopts the principle of heat recovery. By recovering the heat in the discharged humid air and introducing it into the dryer again, the heat energy utilization rate is improved and energy consumption is reduced.

Dingli sludge dryer has the advantages of high heat utilization, compact equipment structure, wide adaptability to sludge moisture content, high product drying uniformity, and low gas consumption. It is suitable for drying urban sludge, electroplating sludge, papermaking sludge, petrochemical sludge, printing and dyeing sludge and other sludge raw materials. The sludge processed by the sludge dryer has a greatly reduced moisture content and reduced volume, which facilitates subsequent processing and resource utilization, such as incineration for power generation, composting, building materials, etc.

Dingli sludge dryer is an efficient, energy-saving and environmentally friendly equipment that can effectively solve sludge treatment problems and improve treatment efficiency and quality.
