Core Viewpoint - The precious metal roasting furnace designed and manufactured by Yixing Zhibo Environmental Equipment Co., Ltd. is an advanced device that integrates efficient pyrolysis, automated control, environmental protection emissions, and energy utilization, widely applied in precious metal recovery, electronic waste treatment, and sulfide ore processing [5]. Group 1: Technology Features and Advantages - The furnace operates on the principle of pyrolysis and gasification under oxygen-deficient conditions, effectively decomposing organic materials and converting them into combustible components like CO and CH4, which are then burned in a secondary combustion chamber, achieving an outlet gas temperature of 1100℃±50℃ [3]. - The design minimizes dust generation during the roasting process, significantly reducing the risk of precious metals being carried away by dust, while the micro-negative pressure design further decreases the possibility of dust escape [3]. - The furnace is equipped with PLC or DCS control systems for centralized control, monitoring, and management automation, enhancing operational safety and reducing the need for manual intervention [3]. - The energy recovery system allows for effective heat recovery, such as hot water or steam, while the multi-stage purification process ensures harmful substances in the flue gas are efficiently removed, achieving over 99% removal efficiency for smoke, heavy metals, and dioxins [3][4]. - The furnace is adaptable to various waste shapes and sizes, typically requiring no pre-treatment, and features a drawer-type feeding design for convenient operation [3]. Group 2: Application Areas and Case Studies - The furnace is widely used in the recovery of electronic waste, precious metal catalysts, and sulfide ores containing precious metals [3]. - In electronic waste recovery, the furnace is utilized to remove organic materials and carbon from waste catalysts, enhancing precious metal recovery rates, with a design capacity of 1000 tons per year, operating 330 days a year, 24 hours a day [3]. - During the processing of sulfide ores containing gold and silver, the furnace reacts with lime materials to convert sulfides into calcium sulfate, facilitating efficient sulfur removal and precious metal recovery [3]. - In industrial waste utilization projects, the furnace processes solid waste containing precious metals, such as activated carbon and resin, through high-temperature roasting to remove organic components and recover precious metals [3]. Group 3: Compliance and Safety Standards - The operation of the furnace must comply with strict environmental and safety standards, utilizing the "3T+E" control principle (temperature, residence time, disturbance, and excess air coefficient) to ensure complete combustion of hazardous waste and reduce harmful gas emissions [4]. - The control system is required to have comprehensive alarm and safety interlock functions to ensure timely shutdown in abnormal situations, preventing safety incidents [4].
