[0006] 3. On the high-temperature solid waste comprehensive recovery line, after the thermal extraction operation is completed, some heat energy is still carried by the solid waste material or hot air into the metal separation operation and tail gas treatment operation. The heat energy entering the metal separation operation will affect the recovery of the metal separation operation rate, the heat energy entering the exhaust gas treatment operation will cause the exhaust gas to fail to meet the emission standards, and will also cause damage to the exhaust gas treatment equipment
[0007] 4. The consistency of the occurrence state of metals in solid waste materials is relatively poor, and the comprehensive recovery rate of the metal separation process cannot meet the requirements

The solution comprises a heat exchange assembly, a metal separation assembly and a waste heat circulation assembly, the heat exchange assembly is used for extracting the heat energy in the high-temperature solid waste through heat exchange, granulating the high-temperature solid waste and then conveying the granulated high-temperature solid waste to the metal separation assembly; the metal separation assembly is used for extracting the magnetic metal and the non-magnetic metal in the granular solid waste materials through a metal separation process and forming tailings; and the waste heat circulation assembly is used for collecting and conveying the hot air extracted with high-temperature solid waste heat energy in the heat exchange assembly to a waste heat recycling device and / or a tail gas treatment device, and tracking, capturing and recycling the heat energy carried by the granular solid waste materials.
Description
technical field [0001] This application belongs to the technical field of resource and energy recovery and utilization, and specifically relates to a solution for comprehensive recovery and utilization of high-temperature solid waste. Background technique [0002] The high-temperature solid waste of iron and steel and various metal smelting enterprises, such as steel slag, contains a large amount of heat energy (up to five or six hundred degrees Celsius) and metal substances. Comprehensive recycling of the heat energy and metal substances contained in high-temperature solid waste can reduce The waste of energy, on the one hand, can avoid pollution and promote environmental protection, which has very obvious social, economic and environmental significance. It is precisely because of this that the competent science and technology departments of various countries have regarded the high-efficiency comprehensive recycling technology of high-temperature solid waste as a high-tech ...
