Verfahren zur Beanspruchung von Partikeln mit Elektroimpulsen und Verwendung einer Vorrichtung zur Beanspruchung von Partikeln

Patent Abstract

The invention relates to a method for stressing particles (100) by means of electric pulses (200) using a device (1) comprising a process column (2) with a vertically oriented process chamber (3), wherein the process chamber (3) has an inlet (4) at an upper end (5) of the process column (2) and an outlet (6) at a lower end (7) of the process column (2), and the process chamber (3) has a substantially constant width (30) between the inlet (4) and the outlet (6). A supply device (8) for supplying particles (100) to be stressed is paired with the inlet (4), and a discharge device (9) for discharging stressed particles (100) is paired with the outlet (6). The process chamber (3) is associated with two electrodes (10) which are provided on different sides of the process chamber (3) and which are connected to an electric pulse generator (11). The particles (100) to be stressed are continuously guided, as a particle bed (150), from the inlet (4) to the outlet (6) through the process chamber (3) and are stressed by means of electric pulses (200) using the electrodes (100). The invention also relates to the use of such a device for stressing particles (100) by means of electric pulses (200) in order to carry out a method according to one of the preceding claims.

Simple SummaryContent extracted with AI.

This invention provides a method and device for treating solid particles using electric pulses as they pass through a vertically oriented process chamber. The particles, arranged as a particle bed, continuously flow from the top to the bottom of the chamber and are exposed to electrical impulses via electrodes on opposite sides of the chamber. This process can pre-weaken or fragment the particles, making subsequent processing, such as crushing or separation, more efficient. The system is designed to avoid blockages and enables higher throughput compared to conventional methods.

Use CasesContent extracted with AI.

• Pre-treatment of ores and minerals before mechanical crushing or grinding to reduce energy consumption.
• Recycling of construction materials (concrete, building debris) by weakening particles for easier separation and size reduction.
• Processing and recycling of electronic waste (e-waste) to facilitate liberation and collection of valuable components.
• Recycling of photovoltaic panels by loosening layers for improved material recovery.
• Industrial separation of composite or multi-phase materials where selective breakdown is beneficial.

BenefitsContent extracted with AI.

• Significantly increases the throughput of particle treatment compared to previous methods.
• Reduces energy requirements in subsequent mechanical comminution steps by pre-weakened particles.
• Enables more efficient and selective particle processing, improving the recovery of valuable materials from complex wastes.
• Decreases the risk of blockages or flow interruptions due to the constant cross-section and design of the process chamber.
• Can process a wide range of particle sizes and materials, allowing for versatile industrial applications.
• Allows for continuous operation and easy adjustment of processing speed to match material properties or processing needs.
• Enhances the homogeneity and compactness of the particle bed, improving treatment efficiency.
