Product Description

Low-Temperature Belt Type Sludge Dryer Introduction

The Low-Temperature Belt Type Sludge Dryer is a high-efficiency, energy-saving, and environmentally friendly continuous operation equipment designed for sludge treatment in municipal sewage treatment plants, chemical factories, printing and dyeing enterprises, and other industries. It adopts a low-temperature drying process (operating temperature 60℃-85℃) combined with a multi-layer stainless steel mesh belt structure, which can efficiently handle sludge with initial moisture content of 80%-95% and reduce it to 10%-30% as required. The equipment operates through a systematic process: sludge is uniformly distributed on the mesh belt via a frequency-converted feeding system, dried continuously by low-temperature hot air (from air-source heat pumps or waste heat recovery devices) in cross-flow/counter-flow, with humid tail gas purified by integrated cyclone dust collectors, bag filters, and deodorization devices to meet national environmental standards (removing over 99% of dust and decomposing odorous substances). Equipped with an intelligent PLC control system for real-time parameter adjustment and multiple safety protections, it features corrosion-resistant materials (304/316L stainless steel, titanium alloy heat exchangers) ensuring an 8-10 year service life, saves 30%-50% energy compared to traditional high-temperature dryers, avoids harmful substance volatilization, and enables resource utilization of dried sludge (as building materials, organic fertilizers, or incineration fuel) while saving floor space with its compact multi-layer design.
