Introduction to Printing and Dyeing Sludge Drying Machine:
The "Double Spiral Sludge Drying Machine" produced by Changzhou Shengwanda Drying Equipment Co., Ltd., including printing and dyeing sludge drying machines, textile sludge drying machines, bleaching and dyeing sludge drying machines, domestic sludge drying machines, petrochemical sludge drying machines, electroplating sludge drying machines, and papermaking sludge drying machines, is suitable for enterprises that generate large amounts of sludge in the printing and dyeing, bleaching and dyeing, papermaking, and leather industries. Currently, there is still a blank in the thorough treatment of sludge both domestically and internationally, and it has been recognized by environmental protection departments.

Printing and dyeing sludge dryer - Overview: 
The "Double Spiral Sludge Drying Machine" manufactured by Changzhou Shengwanda Drying Equipment Co., Ltd. can dry sludge with a moisture content of 80% -90% after dewatering (such as pressure filtration). The moisture content of the dried sludge reaches 20% -30%. After treatment, the heat generation per ton of dry sludge reaches 1200-2000 calories (equivalent to 120-280kg of coal), which can be mixed with coal and burned together in the boiler, completely solving the problem of sludge transportation and landfill.
  
Printing and dyeing sludge dryer - characteristics
All equipment in the local system operates in a sealed manner, with no dust or odor leakage. It is environmentally friendly and can be used as waste, reducing the cost of solid foreign matter disposal for enterprises and saving costs. Its characteristics:
1. QJ sludge dryer has low energy consumption: due to indirect heating, it does not carry a large amount of air and take away heat, and the outer wall of the dryer is also equipped with insulation layer.
2. The QJ sludge dryer has low operating costs: it has a huge heat transfer surface per unit effective volume, which shortens processing time, reduces equipment size, and greatly reduces building area and space.
3. Wide range of material processing: using different heat media, it can handle both thermosensitive materials and materials that require high-temperature treatment. Common media include water vapor, thermal oil, hot water, cooling water, etc., which can be operated continuously or intermittently. Can be applied in many fields.
4. Low environmental pollution: No use of portable air, minimal dust and material entrainment, low solvent evaporation of materials, easy to handle. Closed loop circulation can be used for materials that are contaminated or for conditions that require solvent recovery.
5. Low operating costs: low-speed mixing and reasonable structure, minimal wear and tear, and low maintenance 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 surface. In the axial range, the temperature, humidity, and mixing degree of the material are very small, thereby ensuring the stability of the process.
  
The double helix sludge dryer has been officially launched into the market by our technical personnel after one year of development and research. It has been recognized by the environmental protection department and is currently being used by multiple manufacturers in Zhejiang, Yangzhou, Guangdong, Suzhou, Nantong, and other areas.
