Apparatus and method for producing auxiliary cementitious material
The invention relates to a device for heat-treating solid materials, in particular solid materials in granular form, where the device comprises a kiln and an external heat source, where the device comprises at least two steps arranged above one another, where each step comprises a gas-permeable inclined sliding surface, and where the sliding surface is inclined relative to the kiln. The bed of solid material slides downwards on the gas permeable inclined sliding surfaces within the device due to gravity, and wherein the inclined sliding surfaces of the steps are inclined directly consecutively to each other in opposite directions, and wherein the kiln comprises at least one, preferably at least two, of the steps, and the kiln is configured such that a hot gas generated by an external heat source is directed through the solid material inside the kiln to heat the solid material to a desired temperature, thereby changing the material properties of the solid material. According to the invention, the device comprises at least one gas temperature regulation system comprising a gas outlet in a second one of the steps, a temperature regulation zone, and a gas inlet in a first one of the steps, preferably a temperature regulation zone, the first step is arranged directly contiguous with and above the second step, where at least the first step is one of the at least one step inside the kiln, and where the gas temperature regulation system is adapted such that hot gas is extracted from the second step through the gas outlet, the hot gas is introduced into a temperature regulation zone in which the hot gas temperature is regulated by an external heat source to a regulated temperature and is re-introduced into the first step at the regulated temperature. The invention further relates to a method for producing an auxiliary cementitious material.
本发明涉及一种用于热处理固体材料、特别是粒状形式的固体材料的装置，其中，装置包括窑炉和外部热源，其中，所述装置包括至少两个布置在彼此上方的台阶，其中，每个台阶包括气体可渗透的倾斜滑动表面，所述固体材料床由于重力在所述装置内在所述气体可渗透的倾斜滑动表面上向下滑动，并且其中，所述台阶的所述倾斜滑动表面在相反方向彼此直接连续地倾斜，其中，窑炉包括所述台阶中的至少一个、优选至少两个，并且窑炉被配置成使得由外部热源生成的热气体被引导通过窑炉内部的所述固体材料，以将所述固体材料加热到期望温度，从而改变所述固体材料的物质特性。根据本发明，所述装置包括至少一个气体温度调节系统，该气体温度调节系统包括在所述台阶的第二台阶中的气体出口、温度调节区和在所述台阶的第一台阶中的气体入口，优选地，第一台阶被布置成与第二台阶直接连续并且被布置在第二台阶上方，其中，至少第一台阶是窑炉内部的所述至少一个台阶中的一个，并且其中，所述气体温度调节系统适于使得热气体通过气体出口从所述第二台阶被提取，被引导到温度调节区中，在该温度调节区中，热气体温度由外部热源调节到经调节温度，并在所述经调节温度被重新引入到所述第一台阶中。本发明进一步涉及一种用于生产辅助胶凝材料的方法。
