一种石灰石输送系统的注料控制方法及系统
摘要：
本发明涉及炉内脱硫技术领域，公开了一种石灰石输送系统的注料控制方法及系统，其中所述石灰石输送系统包括从上至下垂直布置的粉仓、收料泵和给料泵，所述注料控制方法包括：检测到给料泵的低料位信号被触发时，执行给料泵进料，使物料由收料泵落入给料泵；在执行预定时间的给料泵进料后，停止向给料泵输送物料；停止向给料泵输送物料后，执行收料泵进料，使物料由粉仓落入收料泵；以及在执行预定时间的收料泵进料后或检测到收料泵的高料位信号被触发时，停止向收料泵输送物料。本发明缩短了石灰石输送系统注料控制步序的循环运行时间，从而提高石灰石输送系统的整体输送出力。
摘要（英）：

The present invention relates to the technical field of inside-furnace desulphurization, and discloses a material injection control method and a material injection control system of a limestone conveying system, wherein the limestone conveying system comprises a powder bin, a material collection pump and a material feeding pump, the powder bin, the material collection pump and the material feeding pump are vertically arranged from top to bottom, and the material injection control method comprises: performing material feeding on the material feeding pump when the low material level signal of the material feeding pump is triggered to make the material fall into the material feeding pump from the material collection pump, stopping the material conveying to the material feeding pump after performing the material feeding on the material feeding pump for the predetermined time, performing the material feeding on the material collection pump after stopping the material conveying to the material feeding pump to make the material fall into the material collection pump from the powder bin, and stopping the material conveying to the material collection pump after performing the material feeding on the material collection pump for the predetermined time or detecting the high material level signal of the material collection pump is triggered. With the method and the system of the present invention, the cycle operation time of the limestone conveying system material injection control procedure is shortened so as to improve the whole conveying output of the limestone conveying system.
