In industrial production, the sludge low-temperature dryer has become an innovative technology for solving the problem of high energy consumption in sludge treatment with its unique energy logic and eco-friendliness. This equipment transforms sludge from a viscous state into a solid product that can be utilized for resource utilization through the deep combination of low-temperature thermal field and dynamic mass transfer mechanism, which not only achieves the ultimate goal of pollution control, but also opens up a new path for energy recycling and material regeneration.
Its core technology lies in the precise regulation of low-temperature heat conduction and water phase change. The equipment adopts a gradient temperature control system. In a mild thermal field, the synergistic effect of porous medium heat transfer and convection heat transfer allows the internal bound water of the sludge to gradually escape. Compared with traditional high-temperature drying, this process avoids the pyrolysis loss of organic matter, retains some volatile substances in the sludge, and retains the energy basis for the subsequent.
The equipment design integrates the concepts of integration and intelligence. The multi-layer mesh belt structure realizes the dynamic matching of sludge thickness and drying rate through inclination adjustment and variable frequency drive; the closed negative pressure chamber combined with the biological filter bed purification technology greatly improves the waste gas removal rate.
The dual leap in environmental benefits and resource value is the core breakthrough of sludge low-temperature dryer technology. More importantly, its low-carbon properties and distributed processing enable small sewage treatment stations and industrial parks to realize sludge resource utilization on site, promoting the transformation of environmental governance from centralized to grid-based.
