The principle of fuming is a reduction and volatilization process, which is to blow air and pulverized coal into the slag in the fuming furnace, generate heat and carbon monoxide after combustion, keep the slag at high temperature, and make the compounds and free ZnO and PbO in the slag reduced to Zn and Pb vapors, the vapor will rise to the upper space of the furnace, meet CO2 or inhaled air and oxidize to zinc oxide and lead oxide again, and are collected in the state of soot. The four walls of the fuming furnace are all composed of water jackets. The lowermost water jacket on the side is provided with a tuyere. The inner wall of the water jacket is welded with Φ16mm and 50mm long pins, and the distance between the nails is 50mm, so that the condensed slag adheres to it and forms slag layer protects the water jacket and reduces heat loss. There is a slag outlet on the water jacket at the front end of the furnace. The lower layer of the water jacket and the inclined flue are water-cooled and circulated, and the upper layer of the water jacket is cooled by vaporization. The tuyere structure adopts a tuyere with a ball valve, and there are two branch pipes. The one near the water jacket is called the primary air coal pipe, and the one outside is the secondary air pipe. In order to prevent pulverized coal from escaping out of the furnace, the secondary air pressure is slightly higher than the primary air pressure (about 100mmHg). There are three air outlets on the upper part of the furnace, which is convenient for operation and observation, and can inhale air oxidized metal vapor.   Fuming Furnace Operational In order to achieve good results in the fuming process, the following conditions must be well controlled:temperature, fuel and air supply volume, slag composition, molten pool depth.   1. Temperature If the temperature is too high (such as exceeding 1350°C), iron deposits or Zn-Fe, Sn-Fe alloys may be formed, which is harmful to the fuming operation. If the temperature is too low, the reduction rate of metal oxides will slow down, the volatilization rate will decrease, the fluidity of the slag will deteriorate, and there may even be a danger of furnace formation, so the temperature in the fuming practice is kept in the range of 1150-1300 °C.   2. Fuel and air supply volume The most active factor affecting the volatilization rate in the fuming process is the air supply volume. Because the temperature in the furnace, the ratio of CO/CO2, the amount of gas, and the vapor pressure of the metal are all related to the air supply volume. The volume of the air supply depends on the pulverized coal consumption and the air utilization coefficient (α). The larger the air utilization coefficient, the higher the thermal effect of the fuel, the greater the partial pressure of CO2, and the higher the temperature in the furnace; the smaller the air utilization coefficient , the thermal effect is reduced, the partial pressure of CO becomes larger, and the reducing ability is enhanced. Pulverized coal is both a reducing agent and an exothermic agent in the fuming process, so the CO/CO2 should have an appropriate ratio during combustion. The air utilization factor actually adopted by the factory is variable. Usually, at the beginning of fuming, an air utilization factor close to 1.0 causes almost all carbon to be burned into CO2 to increase the temperature of the slag. In the reduction stage, adjust the air utilization factor to make carbon into CO as much as possible to improve the reduction ability. 3. Slag composition In practical the actual zinc content of the slag feed into the fuming furnace should be >6%. Below 4%, fuming treatment is uneconomical. Regarding the effect of slag composition on the volatilization rate of zinc, it can be summarized as follows: The increase of CaO content can increase the volatilization rate of zinc; The increase of FeO content in slag has little effect on ZnO activity; The content of SiO2 increases, and the volatilization rate of zinc decreases. Therefore, the silicic acidity of the slag is preferably in the range of 1.1 to 1.2.   4. Molten pool depth The thickness of the slag layer in production is generally in the range of 700- 1000mm above the tuyere area.

In order to realize the clean utilization of hazardous wastes with heavy metals and organic substances, RE TECH has developed a unique low-temperature pyrolysis technology for organic hazardous wastes, which can be widely used in the resource treatment and harmless recycling of waste enamel wires, waste circuit boards, waste tires, and waste lithium batteries with the core equipment of the steel belt-type low-temperature pyrolysis furnace. The technology adopts anaerobic pyrolysis to carry out comprehensive recovery, avoiding the production of a large number of hazardous substances generated by direct incineration, while at the same time, all the organic matter will be converted into reusable products, realizing the recycling of hazardous wastes, and completely solving the problem of environmental pollution in the process of recovery of such resources. This technology has already achieved successful industrial application. Low-Temperature Pyrolysis Furnaces provide a sustainable and efficient solution for the treatment and recycling of hazardous and organic wastes. By converting waste into valuable by-products, they not only mitigate environmental pollution but also contribute to resource recovery and energy efficiency. This technology is especially relevant in modern waste management strategies aimed at reducing the environmental footprint and promoting circular economy principles. Low-Temperature Pyrolysis Technology for Hazardous Waste Treatment Key Features: Steel Belt-Type Low-Temperature Pyrolysis Furnace: The core of this technology is a specially designed pyrolysis furnace that operates at low temperatures. The steel belt mechanism ensures controlled and consistent processing of waste materials, enhancing the efficiency and effectiveness of the pyrolysis process. Anaerobic Pyrolysis: The process occurs in the absence of oxygen, preventing combustion and the release of harmful by-products typically associated with high-temperature incineration. This method significantly reduces the emission of hazardous substances and environmental pollutants. Comprehensive Recovery: The technology enables the complete conversion of organic matter into reusable products. Heavy metals are safely separated and can be reclaimed or disposed of in an environmentally friendly manner. Waste-to-Resource Conversion: Organic components of the waste are transformed into valuable resources such as synthetic gases, oils, and char, which can be repurposed in various industries. This conversion supports a circular economy by reducing waste and promoting the reuse of materials. Applications: Waste Enamel Wires: Efficiently recovers metals and organic insulation materials without the release of toxic fumes. Waste Circuit Boards: Extracts valuable metals and other components, minimizing electronic waste. Waste Tires: Produces reusable by-products such as carbon black and pyrolysis oil, reducing the environmental impact of tire disposal. Waste Lithium Batteries: Safely processes and recovers valuable metals like lithium and cobalt, addressing the growing challenge of battery recycling

As the demand for lithium-ion batteries (Li-ion) continues to grow, especially in electric vehicles (EVs), consumer electronics, and renewable energy storage, the need for efficient recycling processes has become increasingly important. Lithium battery recycling production lines are designed to recover valuable materials from used batteries, reducing environmental impact and providing a sustainable source of raw materials for new batteries. How a Lithium Battery Recycling Production Line Works Collection and Sorting Collection: Used batteries are collected from various sources, including EVs, consumer electronics, and industrial applications. Sorting: Batteries are sorted based on their chemistry (e.g., lithium cobalt oxide, lithium iron phosphate) and condition. This step is crucial because different battery chemistries require different recycling processes. Discharging Safe Discharge: To prevent fires or explosions during processing, batteries are fully discharged in a controlled environment. This step neutralizes the electrical energy stored in the batteries, making them safe for further handling. Shredding and Size Reduction Mechanical Shredding: Batteries are mechanically shredded into smaller pieces, breaking down the battery cells into fragments. This process separates the battery components such as the casing, electrodes, electrolyte, and separator materials. Size Reduction: Additional milling or grinding processes may be employed to further reduce the size of the particles, enhancing the efficiency of subsequent separation steps. Separation and Extraction Magnetic Separation: Magnets are used to separate ferrous materials, such as steel casings, from non-ferrous components. Hydrometallurgical Processing: Involves chemical leaching to dissolve and extract valuable metals like lithium, cobalt, nickel, and manganese from the shredded battery materials. The resulting solution is processed to recover these metals as salts or oxides. Pyrometallurgical Processing: High-temperature furnaces are used to smelt the shredded material, recovering metals in a more concentrated form. This process is often used for recovering cobalt, nickel, and copper. Purification and Refining Precipitation and Filtration: The dissolved metals are precipitated out of the solution, filtered, and purified. This step may involve multiple stages of refining to achieve high-purity metal compounds suitable for reuse in new batteries. Electrolysis: Metals like lithium can be further purified through electrolysis, where an electric current is used to deposit pure metal onto electrodes. Recovery of Non-Metallic Materials Plastics and Electrolytes: The plastics and separator materials are typically separated through flotation or solvent extraction techniques. These materials can be recycled into new products or safely disposed of. Graphite Recovery: Anode materials, often composed of graphite, can be recovered and processed for reuse in new battery anodes. lithium battery recycling plant Advantage: 1. Realization of charged crushing process 2. Low-temperature evaporation of electrolyte for harmless disposal 3. Diaphragm Clean Recovery 4. Highly efficient recovery of polar powders 5. High-precision color sorting 6. Zero discharge of production wastewater 7. Exhaust gas centralized treatment, discharge up to standard 8.
