High-efficiency sludge drying rotary kiln dryer | Energy saving 30%·Moisture content ≤ 10%·Customized solution
Overview of rotary kiln products
Traditional sludge treatment methods (such as landfill and composting) face high costs and secondary pollution risks. XX brand rotary kiln dryer adopts high-temperature indirect heating technology to reduce the sludge moisture content from 80% to below 10%, and reduce the volume by 50%. It can be directly used for incineration power generation or building materials, and complies with the Ministry of Environmental Protection's "Technical Specifications for Sludge Treatment and Disposal" (GB/T 23485-2023).
Core advantages(bold keywords):
• Improved thermal efficiency: multi-layer heat exchange structure design, energy consumption is reduced by 30% compared with traditional equipment
• No tail gas pollution: closed drying + tail gas purification system, meeting the "Comprehensive Emission Standards for Air Pollutants"
• Intelligent control: PLC automatically adjusts temperature (200-600℃ adjustable), speed (0.5-5r/min)
Technical parameter table
| Parameter item | Standard model (RTO-100) | Customized model (RTO-200) |

Three-stage drying process (with flow chart):
1. Preheating section: wet sludge enters the rotary kiln through the screw feeder and initially contacts with 200℃ hot air;
2. Decomposition section: the kiln body is tilted 3-5° and rotates slowly, the sludge evaporates water at 500℃ high temperature, and the organic matter is cracked;
3. Cooling section: the dried sludge is discharged through the discharge port, and the exhaust gas meets the emission standards after cyclone dust removal + activated carbon adsorption.
Application scenarios
1. Municipal sludge: sludge reduction in sewage treatment plants (attached with a sewage plant case: treatment cost reduced by ￥120/ton)
2. Industrial sludge: harmless treatment of hazardous waste sludge in electroplating, printing and dyeing, and pharmaceutical industries
3. Resource utilization: the calorific value of sludge after drying reaches 1500kcal/kg, which can be used for cement kiln co-disposal
Frequently Asked Questions
Q: Will the treatment of sticky sludge stick to the wall?
A: Patented anti-sticking lining + chain crushing device is used, and the wall sticking rate is less than 5%.
Q: How to ensure the life of the equipment?
A: The kiln body is made of 310S stainless steel, corrosion-resistant design, and a 10-year warranty is promised for core components.
