Carbonized steel slag aggregate preparation device and preparation method thereof
The invention relates to a carbonized steel slag aggregate preparation device and a preparation method thereof, the carbonized steel slag aggregate preparation device comprises a flue gas discharge pipe, a flue gas inlet pipe, a rotary carrier roller, a flue gas distributor, a gas guide pipe, a distributing device and a feeding conveying belt, the feeding conveying belt is arranged above one side of a carbonization device, and the flue gas inlet pipe is arranged below the other side of the carbonization device; the smoke inlet pipe is communicated with the smoke distributor, a rotating carrier roller is mounted below the smoke distributor, a distributor and a gas guide pipe are mounted in an inner cavity of the carbonization device, the distributor is located at the discharging position of the feeding conveying belt, the gas guide pipe is located below the distributor, and a smoke discharging pipe is mounted at the top of the carbonization device. The method has the beneficial effects that the alkaline calcium ion chelating agent is added to promote the conversion of f-CaO to Ca < 2 + > and the conversion of CO2 in the flue gas to CO3 < 2-> to accelerate carbonization. The alkaline calcium ion chelating agent is added, so that conversion from f-CaO to Ca < 2 + > can be accelerated, the pH value of the environment can be increased, conversion from CO2 to CO3 < 2-> is promoted, EDTA is recycled, and the effect of a catalyst is achieved.
一种碳化钢渣骨料制备装置及其制备方法，它包括烟气外排管、烟气进气管、旋转托辊、烟气分布器、导气管、布料器、进料输送带，碳化装置一侧的上方安装有进料输送带，碳化装置另一侧的下方安装有烟气进气管，烟气进气管与烟气分布器相连通，且烟气分布器的下方安装有旋转托辊，碳化装置的内腔安装有布料器与导气管，布料器位于进料输送带的出料处，且导气管位于布料器的下方，碳化装置的顶部安装有烟气外排管。本发明有益效果为：添加碱性钙离子螯合剂来促进f‑CaO向Ca2+的转化、以及烟气中CO2向CO32‑的转化来加速碳化。且添加碱性钙离子螯合剂，既可以加快f‑CaO向Ca2+的转化，又可以增加环境的pH值，以促进CO2向CO32‑的转化，EDTA循环使用，具有催化剂的作用。
