Low Temperature Tank Sludge Dryer for Industrial Plants

BOEEP’s low temperature tank sludge dryer delivers a sustainable, cost-effective solution for industrial and municipal facilities struggling with high-moisture sludge disposal challenges. Engineered to handle sludge with initial moisture content up to 83%, this advanced system efficiently reduces moisture levels to an adjustable 10%-30%, achieving up to 90% volume reduction and pathogen sterilization in a single process. Designed for minimal operational overhead and maximum environmental compliance, our sludge drying equipment eliminates the need for pre-treatment steps and supports resource recovery initiatives, making it the preferred choice for chemical plants, papermills, electroplating facilities and municipal wastewater treatment plants worldwide.

Advanced Low-Temperature Drying Technology

At the core of our system lies proprietary low-temperature dehumidification and condensation drying technology, which operates at 40-50℃ (return air) and 60-80℃ (conveying air). Unlike traditional high-temperature dryers that release harmful VOCs and damage heat-sensitive materials, our gentle drying process preserves material integrity while ensuring complete moisture removal.

How Low-Temperature Condensation Drying Works

The closed-loop system circulates warm, dry air through the sludge bed, absorbing moisture before passing through a condensation unit to separate water vapor. The dehumidified air is reheated and recirculated, creating a continuous, energy-efficient drying cycle. This fully enclosed design prevents odor escape and eliminates secondary pollution, while the integrated sterilization process achieves up to 90% pathogen reduction, producing a hygienic end product suitable for safe disposal or further processing.

Unique Three-Layer Mud Bucket Design

A defining feature of our dryer is the patented three-layer mud bucket structure that maximizes heat transfer efficiency. This innovative design increases the contact area between sludge and warm air, enabling consistent, uniform drying across all batches. It allows the system to achieve an industry-leading energy efficiency rating of 2.0-3.5kg H₂O per kW·h, with specific energy consumption as low as 0.25-0.5kWh per 1000kg of water removed.
