Abstract
A system and method for preparing sulphoaluminate cement from solar energy stored heat dried sludge. Solar concentrator connected to high-temperature molten salt storage tank, superheater, preheating-evaporator and low-temperature molten salt storage tank to form mixed molten salt heat transfer-heat storage circulation system; superheated steam in superheater enters ultra-disc dryer, and ultra-disc dryer connected to water storage tank and preheating-evaporator superheater to form water heat transfer circulation system; wet sludge bin connected to ultra-disc dryer and inlet of dried sludge bin, and dried sludge conveyed to dried sludge bin for storage; and cement production system separately connected with waste gas outlet of ultra-disc dryer and outlet of dried sludge bin. System can use valley electricity to supplement heat at any specific time, and coupled with cement kiln; waste gas introduced into cement kiln for waste burning; dried sludge mixed with other solid waste to enter cement kiln to prepare sulphoaluminate cement.
