Title:
GRANULAR MINERAL DRY SORTING SYSTEM BASED ON SOLAR ENERGY AND HEAT STORAGE
Document Type and Number:
WIPO Patent Application WO/2020/168722
Kind Code:
A1
Abstract:
A granular mineral dry sorting system based on solar energy and heat storage, comprising a solar power supply and storage module, a solar photo-thermal module (18), a phase-change heat-storage heating module (3), and a granular mineral dry sorting module. The sorting system applies the solar photo-electric technology, the solar photo-thermal technology, the phase-change heat storage technology, and the heat-pipe phase-change heat transfer technology to the granular mineral dry sorting system, photovoltaic electric energy is stored by an energy storage device (34) to be supplied to an electric heating device (27), real-time dependence of power for the system on the solar energy is reduced. By using a solar photo-thermal and electric heating coupled phase-change material heating manner, large-area constant-temperature heating of a medium in an air duct (30) is achieved, heating is more uniform, and heat pipes (25) are arranged on the bin wall of a cyclone sorter (7), the heat exchange efficiency is high, rapid constant-temperature drying in a sorting bin is achieved, and the dewatering, drying and sorting efficiency are improved. The sorting system has the advantages of energy-saving and environmental protection, simple structure, long service life, high sorting efficiency, and stable and reliable operation.
