Title:
SECONDARY ENERGY STORAGE SYSTEM BASED ON WASTE HEAT UTILIZATION OF IRON AND STEEL PLANT
Document Type and Number:
WIPO Patent Application WO/2022/143978
Kind Code:
A1
Abstract:
Provided is a secondary energy storage system based on waste heat utilization of an iron and steel plant. The energy storage system is provided with a high-temperature secondary battery and a heat source for heating the high-temperature secondary battery. The heat source comes from exhaust gas waste heat and solid sensible heat of an iron-making procedure, a steel-making procedure, a coking procedure and a sintering procedure of an iron and steel plant. The heat source can provide high-temperature waste heat of at least 500ºC for the high-temperature secondary battery. The secondary energy storage system provided in the present invention can acquire electric quantity from a power grid to perform charging at night when the electric energy of the power grid is excessive, and discharges electricity to charge the power grid in the daytime when the electric energy of the power grid is lacking, so that the frequency modulation of the power grid is realized. Electric energy stored in a high-temperature secondary battery can also be provided for the production operation of an iron and steel plant, so that the electricity utilization cost of the iron and steel plant is reduced.
