Product Description
The muddy material drying system developed by Jiutian Company is suitable for drying various kinds of sludge with high viscosity. The sludge drying system operates under negative pressure and is equipped with an enhanced heat transfer device for direct heat transfer. The drying and moisture control of the material is convenient, the operation flexibility is large, and the flow rate of the product is allowed to have a large fluctuation range. There are few high-temperature mechanical equipment in the system, simple structure, easy cleaning, low failure rate, continuous operation, low maintenance cost and wide application range. The sludge dryer system is widely used in activated sludge drying, sewage sludge drying, petrochemical sludge drying, papermaking sludge drying, printing and dyeing sludge drying, tanning sludge drying, electroplating sludge drying, municipal sludge drying , drying of various sludges such as biological fermentation bacteria residues and high-humidity materials such as various slag residues.
The sludge enters the guide plate in the dryer from the feeder through the chute. With the rotation of the cylinder, the sludge is sent to the inclined lifting plate, and then lifted to the center of the cylinder, and gradually falls to form a material curtain. , the high-temperature airflow passes through it, preheating the sludge and evaporating part of the water. When the sludge is spilled and moved to the movable grate-shaped wing, the preheated grate-shaped wing is mixed with the material, and the heat is transferred to the material to evaporate part of the water. At the same time, the material entrained by the wing plate is lifted and sprinkled, repeated many times, and the material exchanges heat with the hot air flow. At the same time, the cleaning device buried in the material also slides down the inner side of the arc-shaped lifting plate to clean the material adhering to the inner wall of the lifting plate. When the cleaning device rotates along the vertical line with the cylinder, it is dragged on the back of the circular arc lifting plate to clean the materials adhering to the outer wall of the lifting plate. With the continuous rotation of the cylinder, part of the water evaporates, and the sludge is further dried. At the same time, the cleaning device also played a role in breaking the sludge pellets, which improved the drying speed. Finally, the sludge was dried and turned into loose materials with low moisture, which were discharged from the discharge port.
1. High security. The advanced circulating air technology guarantees the stable low oxygen content of the sludge drying system and ensures safe operation.
2. Energy-saving and low operating costs.
3. Clean and environmentally friendly. The exhaust gas discharged from the system is treated by the deodorization system and wet spray treatment. It has no dust and no odor and meets environmental protection requirements.
4. Advanced technology and reliable performance. The unique broken arch rapping device effectively solves the problem that the materials are bonded to the machine and the lifting device and the material agglomeration and movement are blocked during the drying process, the drying strength is 3-5 times that of the ordinary drying equipment.
5. The investment cost is low. The wet sludge is dried and granulated in one step in the dryer; the system footprint and auxiliary equipment investment are greatly saved.
6. Strong adaptability, suitable for semi-drying and full drying of sludge. Widely range of applications, the operating parameters can be adjusted according to different types of sludge properties to ensure the stable operation of the system.
7. Simple and convenient operation. It can realize intelligent control, automatic adjustment of operating parameters, and the dryer is always in the best state to ensure uniform and stable sludge moisture.
