Abstract

The invention relates to a device and method for measuring the solid content of a solid-liquid system, and belongs to the technical field of process control in chemical production. The method comprises the following steps: quantitatively sampling a solid-liquid mixture to be detected in a container by a metering pump, injecting the sample into a measuring pipe provided with a jacket layer under the assistance of an electromagnetic valve, allowing the measuring pipe to stand still to carry out layering; making a signal generator and a signal receiver move along the measuring pipe at a constant speed, recording the power change of laser that penetrates the measuring pipe, determining the corresponding volumes of solid and liquid according to the power change, and finally calculating the solid content of the solid-liquid system. The device has the advantages of simple structure, reliable operation, convenient maintenance, direct measuring process, high reliability, and wide application range; can be used to measure the solid content under a normal pressure at a room temperature, and can also be applied to chemical process control and monitoring under a high pressure at a high temperature.

Description

technical field

[0001] The invention relates to a measuring device, in particular to a measuring device and method for measuring solid content in a solid-liquid system, which is suitable for process dynamic monitoring of particle volume in the chemical production process and monitoring in other related fields, and belongs to chemical production process control technology field. Background technique

[0002] With the continuous development of process analysis and control technology, all walks of life have higher and higher requirements for the measurement of solid content in solid-liquid systems, especially in the chemical production process, the requirements for product quality, appearance and other technical indicators are becoming more and more stringent. At present, although the volume of particles in the system can be measured by measuring methods and analytical instruments such as measuring cylinders, beakers, settling chambers, Malvern particle size analyzers, and onli...
