Sludge Drying Collaborative Power Generation Technology - Mobile Crusher

Ba'an Water Management takes sludge thin-layer drying technology as the core and power plant collaborative power generation as the treatment method, forming a complete comprehensive utilization and treatment mode of sludge resources, fully realizing sustainable development and circular economy. In various sludge treatment and disposal processes, the drying process of sludge is the same. Thin layer sludge drying equipment can semi dry or fully dry municipal sludge, industrial sludge, and primary chemical sludge according to process requirements, and combine land use, incineration, landfill and other technologies to treat sludge, so as to meet the requirements of reduction, harmlessness and resource utilization. The collaborative power generation technology of sludge drying and the power generation mode of sludge drying and collaborative power plants make full use of social resources and division of labor to solve the sludge problem. That is, the sewage treatment plant purchases the services of the sludge drying plant to treat the sludge, and the sludge drying plant uses the waste heat steam of the power plant to dry the wet sludge. The condensed water separated from the sludge during the drying process is discharged to the sewage treatment plant for treatment, and the sludge with a certain calorific value after drying is sold to the power plant, forming a fully market-oriented and sustainable business model. The sludge drying collaborative power generation technology provided by Ba'an Water includes a single-stage sludge drying process and a two-stage sludge drying process. The composition of the one-stage sludge drying process system: sludge is received and stored in the conveying system; Sludge drying system; Exhaust gas treatment system; Biological/chemical deodorization system; Dry sludge storage and transportation system; Steam system; Electrical, instrumentation, and control systems. In the one-stage sludge drying process, sludge storage and drying are managed in a closed and negative pressure operation, and odor is fully treated without affecting the surrounding environment. The drying process uses advanced sludge thin-layer drying equipment and recovers heat from the exhaust gas to reduce drying energy consumption and costs. The process is flexible, and a single-stage sludge drying process can be used to dry the sludge to 30-45%.

The two-stage sludge drying process fully utilizes the waste heat from the first stage drying and integrates an energy recovery device to reduce operating costs. During operation, the sludge is molded into particles during the plasticization stage, avoiding the generation of dust. The operating temperature of this process is low (below 110 ℃), ensuring the safety of personnel and equipment.

In the application of sludge drying and incineration technology in the petrochemical industry, advanced thin-layer drying equipment is used to achieve thermal drying of sludge and effectively improve its calorific value. The inerting system, special sealing structure, and multiple emergency safety measures of the thin-layer drying equipment provide safety and reliability for the system. In response to the characteristics of sludge, a two-stage incineration system of "rotary kiln+secondary combustion chamber" is adopted to fully burn the combustibles in the sludge. The system fully recovers the heat generated by sludge combustion and uses it in thin-layer drying equipment, which can meet the majority of drying energy consumption. Adopting a combination of dry and wet methods to treat exhaust gas effectively ensures compliance with emission standards.
