Drying Technology
01 Industry Background
The continuous growth in the production and sales of new energy vehicles has led to the generation of sludge containing heavy metals such as chromium and nickel during the electroplating and painting processes in vehicle manufacturing. This sludge is classified as high-risk waste in the National Hazardous Waste List. Traditional landfilling or simple hot air drying methods for this type of sludge often result in high moisture content (70% -80 %), incomplete removal of internal moisture, and excessive leachate levels during transportation and landfilling. With increasingly stringent environmental standards and rising sludge disposal costs, companies urgently need a treatment method that balances volume reduction, stabilization, and resource recovery.
02 Core Processes and Solutions: Integrated Mechanical Dehydration and Low-Temperature Drying
SHINCCI has been deeply involved in the environmental solid waste drying field for over 20 years . Addressing the pain points of sludge treatment in the automotive industry, they have launched an integrated solution combining mechanical dewatering and low-temperature drying. The entire process first pre-treats the sludge using mechanical dewatering equipment, quickly removing most of the free water and reducing its volume. Then, relying on SHINCCI's core low-temperature drying equipment, it deeply removes internal bound water in a sealed, low-temperature environment, completely solving the problems of external drying and internal wetness, and excessive moisture content associated with traditional dewatering methods. The moisture content of the dried sludge is controllable (adjustable according to needs), significantly reducing hazardous waste disposal costs for enterprises and creating conditions for subsequent resource utilization.
03 Solution Advantages: Three Core Highlights Empower Compliance and Cost Reduction
The solution has three core advantages and is well-suited to the production needs of automakers.
Customized design: Equipment and processes can be flexibly matched according to sludge production, composition, plant site and environmental protection requirements, and can be adapted to various car manufacturers' production lines.
Significant energy savings: Relying on multi-effect heat recovery condensation dehumidification technology, the heat utilization rate is high, saving about 50% more energy than traditional low-temperature drying, effectively reducing long-term operation and maintenance costs and shortening the equipment investment recovery cycle.
Green and environmentally friendly: The entire process is carried out in a closed system, with no dust or odor leakage. Heavy metals are stabilized during the drying process, eliminating secondary pollution and achieving harmless treatment and resource recycling of sludge.
04 Industry Empowerment: Helping Automakers Achieve Win-Win Results in Environmental Protection and Profitability
Low-temperature box-type sludge dryer for the Xpeng Motors project
Leveraging its mature technology, SHINCCI's low-temperature drying solution has been implemented in several new energy companies . Practical application shows that this solution can significantly reduce the cost of transporting and disposing of sludge, allowing new energy vehicle manufacturers to simultaneously achieve resource recycling while ensuring compliant production, thus creating a win-win situation for both environmental protection and economic benefits.
