A Physical Separation System for Metal Impurities in Broken Waste Glass

Abstract

The invention belongs to the technical field of solid waste recycling, and in particular relates to a physical separation system for metal impurities in broken waste glass. The system combines various physical separation technologies such as magnetic separation, eddy current separation, and high-voltage electrostatic separation. Compared with wet recovery technology, the whole process is operated without water, and each metal component in the waste glass mixture has been efficiently recovered. Sorting and purification realizes anhydrous purification of metal components in waste glass and avoids secondary pollution. Compared with the prior art, the physical separation system of metal impurities in waste glass of the present invention has a wide range of applications and fewer limiting factors, and the waste glass purification technology developed based on this device avoids the problem of wastewater pollution in wet recovery technology, and also The efficient recovery of various metal components in waste glass provides a new technology for the green and efficient recovery of waste glass.

Description

technical field [0001] The invention belongs to the technical field of solid waste recycling. More specifically, it relates to a physical separation system for metal impurities in crushed waste glass. Background technique [0002] Due to its complex composition, low recycling value, and secondary pollution during the recycling process, the treatment and recycling of waste glass has not been valued by people. Among them, metal accounts for 1% to 3% of waste glass. Due to the low content, its resource recovery has been ignored by people, resulting in high metal impurities in the recycled waste glass, which greatly affects the subsequent in-depth resource utilization of waste glass. At the same time Also caused the waste of metal resources. A large amount of waste glass is exposed to the environment, occupying land resources, and there is also the risk of metal impurities polluting the environment. With the massive generation of construction waste, domestic waste, and electr...
