1. Introduction of rotary dryer design
Rotary dryer design calculations, refers to designing drying machine for drying a large number of materials.
Due to reliable operation, flexible operation, strong adaptability and big processing capacity, it is widely used in metallurgy, building materials, light industry and other sectors.
Rotary dryer design calculationsr is generally suitable for granular material, and can also be partially mixed with dry material to dry viscous paste material or material with high moisture content, and has been successfully used in granulating drying of solution material (slurry).
2. Application of rotary dryer design
3. Working Principle of rotary dryer design
(1) When the sludge dryer works, the sludge passes through the chute into the guide plate of the dryer. With the rotation of the cylinder, the sludge is led to the center of the drum, which is promoted to the center of the cylinder, and gradually sprinkles to form the material curtain.
(2)The air with high temperature flows through the raw material, preheating and evaporating some moisture. When the raw material is sprayed and moved onto the movable grate fender, the material is mixed with the preheated grate flange, which transfers heat to the material and evaporates part of the moisture.
(3) At the same time, the flood-out pattern which is buried in the material, sprinkles, repeat many times, the material and heat flow convection and contact heat exchange. Also buried in the material cleaning device, also along the arc The inner side of the lifting plate slips, cleaning the material attached to the inner wall of the lifting board.
(4) When the cleaning device turns the vertical line with the cylinder, it is then dragged on the back of the arc lifting plate, and the material adhered to the outer wall of the lifting plate is swept down.
(5)With the continuous rotation of the cylinder, some moisture evaporates and the sludge is further dried.
At the same time, the cleaning device also played a role in breaking the sludge ball, improving the drying speed, the sludge became a loose material with low moisture content after drying, and discharged from the outlet

5. Characteristics of rotary dryer design
(1) Intensification. As a result of adopting the device operation, the equipment arrangement is compact, the occupation area is small, it can be arranged in the sewage treatment plant, and the storage and transportation cost of the wet sludge can be saved.
(2) Mechanization. At present, more drying equipments are operated automatically, which are safe, efficient and stable, and accord with the trend of industrialization.
(3) Reduction. Drying can greatly reduce the volume and mass of sludge and facilitate transport and absorption.
(4) Harmlessness. Pasteurization of sludge, elimination of pathogens, drying of dirt Mud character is a safe guard.
(5)Stabilization. After drying, the water content of raw material was lower than 10%, the microbial activity was inhibited, the raw material was stable, it could not rot and smell, and could be stored and transported for a long time.
Drying products can be made into granular fertilizer for farmland fertilization, but also as fuel to burn.
