6 FAQs about [Hydraulic punching of photovoltaic panels]

How is high-voltage pulse crushing used in photovoltaic panel treatment?

High-voltage pulse crushing technology was applied to photovoltaic panel treatment.Crushed products were separated by sieving and dense medium separation. Glass was in the 45–850 μm fraction and purified by dense medium separation. Ag was highly condensed (3000 mg/kg) in the sieved products.

How to separate a photovoltaic panel?

In this study, we crushed a photovoltaic panel by high-voltage pulse crushing and then separated the products bysieving and dense medium separation with the aim of selective separation and recovery of various materials in the panel.

How are high-voltage pulse crushing experiments performed?

High-voltage pulse crushing experiments were performedwith a SELFRAG Lab S2.0 instrument (SELFRAG AG, Switzerland). After a piece of the cut panel was put on the bottom electrode in the vessel, the crushing experiments were conducted under the conditions listed in Table 2.

What are the disintegration mechanisms in high-voltage pulse crushing?

We considered that there are two main disintegration mechanisms in high-voltage pulse crushing, namely,electrical disintegration (ED) and electrohydraulic disintegration (EHD). In the ED mechanism, breakdown occurs in the solid materials through the application of a high voltage, resulting in selective crushing of the materials’ boundaries.

Can high-voltage pulse crushing be commercially viable?

Furthermore, processing costs in the high-voltage pulse crushing were estimated to be 0.21 JPY/W (about 0.0019 USD/W), which showspotential for commercial viability. This research was supported by the Environment Research and Technology Development Fund ( 3K162004) of the Ministry of the Environment, Japan.

What is the gap between electrodes in high-voltage pulse crushing?

In our high-voltage pulse crushing experiments, the gap between the electrodes was set to be20 mm; however, for a discharge voltage of 90 kV the gap was set to be 10 mm because electrical breakdown did not occur when the distance was set at 20 mm.
