Mineral admixture modification device and mineral admixture modification method
The invention provides a mineral admixture modification device and a mineral admixture modification method. The mineral admixture modification device is composed of an air pump, an air pressure valve,an ultrasonic atomizer, a steam generator, a Y-shaped air delivery pipe, a fluidized bed reaction chamber, a material inlet, a collector, a dust collection filter and a condensation pipe. According to the invention, in combination with a fluidized bed vapor deposition method, a mineral admixture is modified by adopting a chemical reagent, the preparation method is simple in operation process, themodifier is uniform in deposition and small in deposition scale, the volcanic ash reaction activity of the mineral admixture can be effectively improved, and the performance of concrete is improved;and compared with the traditional method of directly mixing and stirring the modified solution and the mineral admixture, the method of the invention has the advantages that the volcanic ash reactionactivity of the mineral admixture obtained by the method is remarkably improved, and under the condition of the same volcanic ash reaction activity of the mineral admixture, the cost can be reduced, and the energy consumption can be reduced.
本发明提供一种矿物掺和料改性装置及矿物掺和料改性方法，该装置是由气泵、气压阀门、超声雾化器、蒸汽发生器、Y型输气管、流化床反应室、进料口、收集器、收尘过滤器、冷凝管组成，本发明结合流化床气相沉积法，采用化学试剂改性矿物掺合料，操作过程简单，改性剂沉积均匀且沉积尺度小，能有效提高矿物掺合料的火山灰反应活性，改善混凝土性能。将本发明方法与传统的采用改性溶液与矿物掺合料直接混合搅拌的方法进行对比，采用本发明得到的矿物掺合料的火山灰反应活性显著提高，在相同矿物掺合料火山灰反应活性的条件下，采用本发明能降低成本，减少能耗。
