product details
The complete set of equipment for sludge centrifugal dewatering treatment (sludge concentration dewatering equipment) is an important equipment in chemical sludge treatment, sludge treatment in tap water production processes, and industrial and agricultural wastewater treatment projects. It has the integrated treatment function of sludge dewatering and sludge concentration dewatering. Internationally, a fully enclosed continuous operation large aspect ratio horizontal spiral discharge settling centrifuge is generally used as the main machine for sludge dewatering. Nowadays, sludge paddle blade dryers are more suitable for integrated drying and dewatering of sludge.

Advantages that the device does not have:
1. Fully enclosed operation, clean and pollution-free on-site;
2. Low usage of coagulants and cleaning water, resulting in low daily operating costs;
3. The equipment layout is compact and occupies a small area, which can significantly reduce land acquisition and infrastructure investment.
The sludge concentration and dewatering integrated machine manufactured by Shengwanda has a long main body and slow speed. The entire processing of sludge cutting, spiral feeding, spiral discharging, transportation, flocculant addition, and monitoring of the entire system operation are all implemented by a PLC+LCD control system. For users, this device, as a fully automated complete set of operating units, is an ideal turnkey project.

The process flow diagram of the complete set of sludge dewatering equipment manufactured by Saint Wanda is as follows:

Working principle of chemical sludge dryer:

Wedge shaped hollow blades are densely arranged on the hollow shaft, and the heat medium heat transfer oil flows through the blades through the hollow shaft, with a large heat transfer area per unit effective volume. The heat transfer medium flows through the shell jacket and hollow stirring shaft through the rotary joint. The hollow stirring shaft has different internal structures according to the type of heat medium to ensure the best heat transfer effect.
At the same time as the jacket is heated by the heat medium, the upper part of the discharge port is simultaneously dehumidified, which greatly increases the drying strength of the equipment. The evaporated water is carried out of the dryer by the dehumidification fan.
Equipment characteristics:
1. Low energy consumption of sludge dryer: Due to indirect heating, there is no large amount of air carried away to remove heat, and the outer wall of the dryer is also equipped with insulation layer, so the heat loss is very small.
2. The sludge paddle dryer system has low cost: it has a huge heat transfer surface per unit effective volume, which shortens the processing time. The device size has decreased, reducing the footprint.
3. Wide range of material processing: Using different heat media, it can handle both thermosensitive materials and materials that require high-temperature treatment.
4. Low environmental pollution: carrying very little air and carrying very little dust material.
5. Low operating costs.
6. Stable operation: Due to the special compression expansion stirring effect of the wedge-shaped blade, the material particles are fully in contact with the heat transfer area. In the axial range, the temperature, humidity, mixing temperature, and gradient of the material are very small, thereby ensuring the stability of the process.
