Abstract

Abstract

The comprehensive utilization of metallurgical mineral solid waste is an important part of building a green and low-carbon circular economy system. In this paper, the vanadium-extracted and discarded slag is used as raw material, and the vanadium-extracted and discarded slag solar thermal collector coating is prepared by iron removal, ball milling, beating, and spraying. As the medium, the heat collection performance at different inclination angles was studied. The results show that when the inclination angle is 30°, the heat collection efficiency of the vanadium-extracted spoil coated heat collector plate is the best, which can reach 84.69%. The heat collection efficiency of the titanium film-coated collector plate is 6.81% lower. It shows that the vanadium-extracted waste slag used as a solar collector coating has a feasible technology, low price and important significance for solid waste reuse.
