Abstract

The invention relates to grate cooler equipment of a cement clinker production line, in particular to an intelligent control system and method for a grate cooler. The intelligent control system and method are aimed at solving the problems that the grate cooler of the current cement clinker production line has large workload of operators, poor operation stability, unstable clinker quality, low heatrecovery efficiency and the like, and is not timely controlled. The control system and method can collect a number of important parameters related to the control of the grate cooler; and by programming a control algorithm based on the control experience of excellent operators, the control system can automatically analyze the change trend and change rate of each parameter, and automatically adjusts the grate speed of the grate cooler by integrating the change trend and change rate of each parameter, thus, the stable operation of the grate cooler, the clinker quality and the stability of the heat recovery efficiency are ensured, and meanwhile the workload of the grate cooler operator is greatly reduced.

Description

technical field [0001] The invention is suitable for a grate cooler system of a new dry-process cement clinker production line, and specifically relates to an intelligent control system and method for a grate cooler. Background technique [0002] The grate cooler is an important host equipment in the clinker burning system of a cement plant. Its main function is to cool and transport the cement clinker, and at the same time provide hot air for the rotary kiln and calciner. It is the heat recovery system of the clinker burning system. main equipment. The stability of its operation is directly related to the quality of clinker and heat recovery efficiency. At present, the control and adjustment of grate coolers in most cement plants are done manually by operators. Since there are many parameters related to grate coolers, the relationship between them is relatively complicated. , closely relying on manual control and adjustment, firstly, the workload is heavy and the efficienc...
