AI Technical Summary
Existing technologies have failed to effectively address insulation degradation and thermal breakdown under extreme conditions in solid waste-based high-temperature thermal storage devices, and lack a thermal-electric synergistic management mechanism, resulting in limited thermal efficiency and electrical performance of the thermal storage system.
The structure consists of a core rod, a heat storage and insulation layer, a gradient insulation layer, and a shell, arranged from the inside out. By utilizing the multi-layer design and self-healing mechanism of the gradient insulation layer, combined with thermal-electric synergistic management, an external electric field is formed through the vacuum suction port. The electric field distribution is regulated and self-healing is triggered when the temperature exceeds the threshold, thereby improving the insulation performance.
The insulation performance was improved under extreme operating conditions, thermal breakdown was suppressed, and long-term operation of the high-temperature thermal storage device was achieved, while improving thermal efficiency and electrical performance.
