Rotary kiln dryers have been widely used in sewage treatment plants, chemicals, pharmaceuticals, food, and other industries to dry sludge containing a lot of moisture. The sludge treated by this equipment not only has a greatly reduced volume but is also easy to handle or dispose of in the future, reducing the cost of handling and transportation.
The rotary kiln dryer for sludge drying is an efficient and environmentally friendly equipment specially designed to treat moisture in industrial sludge, reduce its volume, and facilitate subsequent treatment or disposal.
Working principle of rotary kiln dryer for sludge drying
The rotary kiln dryer uses an internal rotating cylinder to make the sludge tumble in the cylinder and fully contact with hot air or heat medium, thereby evaporating the moisture in the sludge. As the cylinder rotates continuously, the sludge gradually moves from the feed end to the discharge end to complete the entire drying process.
Equipment features of rotary kiln dryer
1. Efficient drying: The rotary kiln dryer adopts indirect heating, has high thermal efficiency, can fully contact with the sludge, and ensures that the moisture in the sludge evaporates quickly. Depending on the different models and sludge properties, the processing capacity can range from thousands of kilograms to tens of tons.
2. Environmental protection and energy saving: During the operation of the equipment, through a reasonable exhaust system and exhaust gas treatment device, the emission of exhaust gas and dust can be effectively reduced to meet environmental protection requirements. At the same time, the use of a waste heat recovery system can improve energy utilization efficiency and reduce energy consumption.
3. Safe and reliable: The rotary kiln dryer adopts an advanced control system to monitor the operation status of the equipment in real-time to ensure the safety and reliability of the equipment. In addition, the equipment has a sturdy structure, long service life, and low maintenance cost.
Technical specifications of rotary kiln dryer
1. Processing capacity: Depending on the specific model and the nature of the sludge, the processing capacity can range from thousands of kilograms to tens of tons.
2. Water content: After drying, the water content of the sludge can be significantly reduced, and the specific value depends on the equipment model and the nature of the sludge. For example, from the initial 30% to 15% or lower.
3. Heating method: A variety of heating methods such as gas, steam, electric heating, heavy oil, coal-fired hot air furnaces, etc. can be used to meet the needs of different users.
4. Speed and inclination: The speed and inclination are set according to the equipment model and sludge characteristics to ensure the best drying effect.
