Principle of online detection of gypsum slurry concentration and density

Thread Content

The concentration of gypsum slurry is detected online via soft sensing; since it is a contactless method, it overcomes the problems of wear and instability associated with traditional instruments. Moreover, this detection method does not require any additional hardware to be installed in the absorption tower, allowing for real-time monitoring that is stable and reliable, and making it easy to measure the concentration and density of the gypsum slurry. The principle behind this type of detection is based on soft sensing: by measuring parameters such as the current of the circulation pump, the stirring current, the slurry level, and temperature, and feeding these values into intelligent instruments, it is possible to calculate the concentration and density of the gypsum slurry with high accuracy, using the system’s mathematical model.
