Rotary sludge dryer

The main structure of the Rotary sludge dryer is a steam tube rotary drum type, which uses water vapor as a heat source to complete drying of lignite, coal slime and the like. Our company can design and manufacture according to user requirements and material specific conditions. Especially steam heating systems such as air intake, gas separation and backwater have unique innovations compared with traditional structures, which can effectively improve the condensate drainage.

The device is a cylinder that is mounted on the support device with a certain inclination and is driven by the transmission to rotate slowly. The material is added from the feeding end of the cylinder. Since the cylinder is installed obliquely, the material in the cylinder moves along the axis while rolling in the circumferential direction, and slowly flows through the entire cylinder from the feeding end of the cylinder, and discharges the cylinder at the discharging end. body. The water vapor enters from the rotary joint located at the discharge end of the drum, and then enters hundreds of tubes through the gas-dividing bag and the gas-dividing pipe. The condensed water in the pipe and the steam are discharged in the opposite direction through the gas-dividing bag and the rotary joint. During the process of turning and moving the material in the cylinder, high-efficiency heat exchange is performed with the outer wall of the tube to complete the drying process of the material.
