Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional AC high voltage transformers are used to power gliding arc discharge reactors, then the system is reliable and robust, but energy losses occur due to thermal effects and energy yield is limited
Solution Approach 1:
The patent applies pulsed power supply to generate periodic high voltage pulses instead of continuous AC power. This pulsed operation mode allows the system to achieve higher peak power densities and energy yields while reducing average power consumption and thermal losses, directly resolving the energy efficiency contradiction
Solution Approach 2:
The patent changes the electrical parameters by using pulsed voltage instead of continuous AC voltage. This parameter change enables the discharge to operate in a different regime with improved energy efficiency, achieving 150 times higher energy yield for dye destruction and 270 times higher for hydrogen peroxide formation
2Productivity
If continuous AC power is used in gliding arc reactors, then the discharge is stable, but the energy yield for chemical transformations is limited
Solution Approach 1:
The pulsed power supply creates periodic discharges with high peak power followed by rest periods. This periodic action allows accumulation of reactive species during the pulse and their subsequent reaction during the off-period, significantly enhancing the energy yield for chemical transformations while maintaining discharge stability
Solution Approach 2:
The pulsed power supply prepares the plasma environment during each pulse by generating high concentrations of reactive species, which then perform chemical transformations during the subsequent period. This preliminary action of species generation during pulses leads to enhanced productivity in the following period
