Domestic waste to fuel (RDF/SRF): Pretreatment stage
The first step in converting domestic waste to fuel (RDF/SRF) is pretreatment. This stage includes collection, transportation and preliminary sorting. Professional garbage collection trucks transport domestic waste from residential areas to treatment plants, and separate non-combustible materials such as metals and glass through an automated sorting system. These materials will be recycled to reduce resource waste.
The key to the pretreatment stage is crushing and drying. The sorted domestic waste enters the crusher and is crushed into uniform small particles. Subsequently, the material enters the drying system and is dried with hot air to reduce the moisture content. This process increases the calorific value of the waste and creates conditions for subsequent processing. The exhaust gas generated during the drying process is purified to ensure that the emission meets the standards.
Quality control in the pretreatment stage is crucial. Technicians regularly test the particle size, moisture content and calorific value of the material to ensure that it meets production requirements. By accurately controlling the parameters of each link, qualified raw materials are provided for subsequent processing. The refined management of this stage directly affects the quality of the final fuel product.
Efficient operation in the pretreatment stage requires advanced equipment support. Modern treatment plants are equipped with intelligent control systems to achieve full-process automation. This not only improves processing efficiency, but also reduces labor costs, providing reliable guarantees for the resource utilization of domestic waste.
