Recycling of Glass from Solar Modules
Methods and apparatuses recycle glass from used solar modules. Particular embodiments combine optical interrogation such as X-Ray Fluorescence (XRF) with computer-controlled dispensing, in order to obtain refined glass having substantially uniform properties. Such glass properties can include but are not limited to one or more of: elemental content (e.g., Iron), optical transmittance, physical resilience (e.g., resistance to weather damage), and texturee.g., to assist in forming an anti-reflective coating (ARC) and/or encapsulant adhesion. Such optical interrogation is combined with computer-controlled dispensing that regulates the release of glass material through a gate, until one or more specific criterion are met.
Waste photovoltaic module processing method
This waste photovoltaic module processing method is a method of continuously treating a waste photovoltaic module. The method includes a heating step of heating a photovoltaic module having a resin back sheet, etc. in a thermal decomposition furnace to melt and oxidatively decompose resin components included in the photovoltaic module, in which the heating step is performed by moving the photovoltaic module in the thermal decomposition furnace from an inlet of the thermal decomposition furnace toward an outlet in a state where the photovoltaic module is placed on a porous ceramic support (A), and the ceramic support (A) is placed on a porous material (B) carrying a transition metal oxide, and an inside of the thermal decomposition furnace includes a temperature rising section in a stage where a temperature of the photovoltaic module rises, and a combustion section in a stage where the resin components are oxidatively decomposed, and an oxygen concentration in the combustion section is controlled to a range from 6 vol % to less than 15 vol %.
Method of pyrolysis for waste light-emitting electronic components and recovery for rare-earth element
The invention disclosed a method for recycling rare earth elements from waste light-emitting electronic components by pyrolysis and alkaline melting-acid leaching. Based on the pyrolysis properties of the organic polymer, through catalytic pyrolysis of the organic polymer material in electronic components and convert the carbon in the residue into water gas, realize high-efficient dismantling of waste electronic component packaging materials. The traditional problems that the compositions of waste light-emitting electronic components are difficult to disassemble are solved, the generated pyrolysis gas and water gas can continuously supply energy for the pyrolysis system and recover the heat in the flue gas to save energy. Meanwhile, based on the chemical dissolution reaction mechanism of phosphors, the combination process of alkali melting, and acid leaching is used to efficiently recover rare earth elements from the waste light-emitting electronic components, and the step leaching of rare earth elements is realized. The rare earth oxalate can be recovered by precipitation, which greatly reduces the difficulty of late separation and purification.
METHOD FOR THE INCINERATION OF WASTE CONTAINING FLUORINE AND NOBLE METALS
A method for the incineration of waste containing fluorine and noble metals in a chamber furnace, the fluorine content of the waste lying in the range of >5 to 70 wt. %, and the noble metal content of the waste lying in the range of 0.1 to 30 wt. %, and the furnace chamber of the chamber furnace being lined with a chromium corundum material comprising 80 wt. % alpha-Al.sub.2O.sub.3, 1 to 20 wt. % Cr.sub.2O.sub.3 and 0 to 5 wt. % SiO.sub.2.
Waste-plastic oil conversion device
A waste-plastic oil conversion device includes a primary decomposition tank that generates a decomposition gas by melting waste plastic; a secondary decomposition tank that generates a low boiling point decomposition gas by heating a liquefied component generated by condensing a high boiling point component out of the decomposition gas generated by the primary decomposition tank at a temperature lower than a temperature in the primary decomposition tank; a melting tank that melts a plastic material that forms a solar battery panel so as to separate the plastic material into the plastic material and a valuable material; and a first storage tank that condenses and stores the decomposition gas and the low boiling point decomposition gas therein. The melting tank is connected to the primary decomposition tank so as to introduce the decomposition gas into the melting tank.
