Tenesun, a professional manufacturer of heat pump environmental protection drying equipment, announced the successful commissioning and formal operation of its heat pump low-temperature belt sludge dryer delivered to a Vietnamese customer at the beginning of this year. The stable operation of the equipment marks that Tenesun’s large continuous sludge drying equipment has achieved stable market landing in Southeast Asia’s printing and dyeing industry, providing a fully automatic, zero waste heat dependent sludge disposal solution for local printing enterprises.
The Vietnamese purchasing enterprise generates 15 tons of printing and dyeing sludge every day in its daily production process. Before introducing Tenesun’s drying equipment, the enterprise faced prominent environmental and cost pain points in sludge disposal.
The printing and dyeing sludge contains a large amount of printing ink, additives and fiber residues, with an initial moisture content as high as 58%. Direct outward transportation of wet sludge requires high transportation costs, and random stacking will cause seepage pollution and odor diffusion, which cannot meet the increasingly strict local environmental protection emission standards.
After adopting Tenesun heat pump low-temperature belt sludge dryer, the equipment steadily reduces the moisture content of 58% wet printing sludge to below 30% through closed low-temperature heat pump circulation drying technology. After drying, the sludge volume is greatly reduced, the transportation and subsequent disposal costs are cut significantly, and the closed operating structure completely avoids odor overflow and sewage leakage, perfectly complying with Vietnam’s industrial solid waste treatment regulations.
The heat pump low-temperature belt sludge dryer is Tenesun’s core large continuous drying product, which is completely different from the batch box-type sludge dryer on the market.
Fully automatic continuous operation
This equipment adopts a multi-layer stainless steel mesh belt continuous conveying structure, realizing 24-hour unattended automatic drying operation covering sludge feeding, layered low-temperature dehumidification and dry material discharge.
Safe low-temperature closed drying process
Supported by closed heat pump heat recovery technology, the whole drying process runs at low temperature between 40℃-80℃. Compared with traditional high-temperature flue gas drying, it will not cause the decomposition of harmful substances in sludge and secondary flue gas pollution. Its heat recovery efficiency exceeds 70%, greatly cutting the comprehensive energy consumption of sludge treatment.
This model is specially oriented to large sludge treatment scenarios with high automation demand and no available waste heat on site. It has wide adaptability to various industrial sludge and organic waste, covering the following industries:
Municipal sludge
Printing & dyeing sludge
Papermaking sludge
Electroplating sludge
Chemical sludge
Leather sludge
Pharmaceutical residues
Kitchen waste
For industrial parks and manufacturing plants without boiler waste heat, steam heat source and other auxiliary heating conditions, the all-in-one heat pump belt dryer can independently complete the whole drying process without supporting heating facilities, with strong on-site adaptability and flexible layout.
Minimum Order Quantity (MOQ): 1 set
Production Lead Time: 30–45 days
Customization: Customizable models based on customers’ daily sludge output
The standardized production system can quickly respond to the urgent sludge disposal renovation demands of global environmental protection enterprises.
Up to now, Tenesun’s sludge heat pump drying equipment has been exported to Southeast Asia, the Middle East and many other overseas regions. The brand has accumulated mature application cases in printing, chemical and municipal environmental protection industries, winning consistent recognition from overseas customers with stable operation performance and low operating cost advantages.
With the stricter global solid waste environmental protection policies, industrial sludge harmless reduction treatment has become an inevitable development trend.
Tenesun will continue to optimize the heat pump low-temperature belt drying technology, launch more energy-saving and large-capacity equipment models, and provide reliable, automatic and economical sludge drying overall solutions for industrial enterprises all over the world.
