Sludge Low Temperature Belt Dryer

BOEEP Environmental Protection is a leading manufacturer of advanced environmental protection equipment. Our independently developed sludge low temperature dryer is designed to solve the most pressing challenges in sludge disposal: high volume, high transportation costs, and environmental risks. This innovative equipment can directly dry sewage or sludge with a moisture content of less than 83% to dry sludge with a moisture content of 10%-30%, achieving up to 90% volume reduction and 90% effective sterilization.

The dry sludge produced can be further processed through gasification, co-combustion, composting, or used as building materials, enabling complete harmless and resource-based disposal. With low energy consumption and zero pollution, our heat pump sludge dryer is widely adopted by municipal authorities and industrial clients across various sectors.

Working Principle of Sludge Low Temperature Dryer

Low Temperature Drying Principle

Our low temperature sludge drying equipment utilizes the principle of low-temperature heat pump dehumidification combined with convection hot air drying. Wet sludge is evenly spread on a mesh belt and transported through the drying chamber. The entire system adopts a fully enclosed design, ensuring no heat loss during the drying process.

Dehumidification Heat Pump Principle

The refrigeration system cools and dehumidifies humid air exhausted from the drying room, while simultaneously recovering the latent heat released during moisture condensation to reheat the dry air. This innovative combination of dehumidification and heat pump technology enables efficient energy recycling throughout the drying process.
