Intelligent control system and method for dense medium separation process

Abstract

The invention relates to an intelligent control system and method for a dense medium separation process, and belongs to the technical field of separation processing. The problems that density settingof existing separation depends on experience to a greater extent, other factors which influence separation density are not considered comprehensively, product quality control lags behind, and a control system is intervened manually are solved. The intelligent control system includes a first ash content measurement device for measuring raw coal ash content, a second ash content measurement device for in-time measuring clean coal ash content obtained after raw coal is separated by a circulating medium, a production index prediction module for processing the raw coal ash content and the clean coal ash content to obtain a circulating medium density set value and a circulating medium density adjustment module, wherein the circulating medium density adjustment module adjusts the circulating medium density based on a deviation between the circulating medium density set value and the measured value of the circulating medium density. According to the intelligent control system, the dependence of the separation density setting process on experience is effectively reduced, historical data are fully used, and the timeliness of product quality control is improved.

Description

technical field [0001] The invention relates to the technical field of sorting and processing, in particular to an intelligent control system and method for a dense medium sorting process. Background technique [0002] The dense medium coal preparation technology is an important separation technology in the coal preparation industry. It is widely used because of its good separation effect. The density of the dense medium determines the quality of the separation effect, so the separation of the dense medium can be controlled in real time. Density is essential. The density control method of the existing coal preparation plant is to manually set the circulating medium density value of the dense medium system (hereinafter referred to as the set density), and to use the PID algorithm to track the set density to carry out systematic density control; mainly there are the following defects: (1) The setting density is set by the operator, which largely depends on experience and is n...
