Abstract

The invention belongs to the technical field of cinder recovery, and particularly relates to a recovery system and method of magnetized cinder of high-Fe sulfuric acid. The recovery system comprises a sulfur concentrate acid preparing system, a cooling system and a cinder conveying system, wherein the magnetized cinder obtained after sulfur concentrate is processed in a roasting furnace is respectively treated by a waste heat boiler, a cyclone dust collector, an electric dust collector, a cinder heat exchanger, pneumatic transmission and the like, and high temperature cinder is cooled and recovered. The magnetized cinder provided by the invention is conveyed in a pneumatic manner, thereby not only thoroughly eliminating the environmental pollution caused by the conventional cooling and humidifying process, but also saving a lot of water resources and water treatment investment. The obtained magnetized cinder does not need to be dried, thereby effectively avoiding energy consumption for oxidization and subsequent drying of the magnetized cinder.

Description

technical field [0001] The invention belongs to the technical field of slag recovery, and in particular relates to a recovery system and a recovery method for ferric sulfuric acid magnetized slag. Background technique [0002] The traditional high-sulfur concentrate roasting device adopts the dry discharge process. The slag produced by the roasting furnace, waste heat boiler, cyclone dust collector, and electric dust collector is lowered to about 400°C by the buried scraper conveyor, and then Send it to the submerged cooling drum through the star feeder for cooling, and then transfer it to the humidifier for humidification after the temperature drops to about 100°C. The humidified slag passes through the product workshop silo of the large-inclination belt conveyor, and its Process flow chart such as figure 1 shown. The disadvantage is that the use of water resources to indirectly cool the slag, not only the cooling effect is poor, the equipment is severely corroded, freque...
