Real-time online detection of the concentration and viscosity of the components in the mixed solution. What equipment is used?
A: At present, the instruments for detecting the concentration of the solution on the line are mainly rotary viscometer, online refractive index meter, ultrasonic concentration meter and microwave concentration test instrument.
The optical fiber on-line concentration sensor measures the concentration by the corresponding relationship between the refractive index and the concentration of the solution, due to the change of the slurry temperature and other residual debris of the slurry deposited on the measuring prism and the slurry in the industrial production process - such as textile sand The fibers often left in the slurry have a relatively large influence on the refractive index. In order to avoid the measurement error, the prism needs to be flushed with steam or high-pressure water at a certain cycle. Ultrasonic concentration meters and microwave concentration test instruments are all present, and the cost is high and the structure is complicated. Moreover, the ultrasonic measurement method needs to have powerful digital signal processing capability and hardware support, and the installation method of the sensor is also complicated, and the application is limited. At present, the more mature online concentration detection in the international textile industry is to measure the slurry concentration by optical refractometer. The rotary viscosity on-line measurement method is complicated due to the complex structure of the torque measuring rotor, the cost is high, the viscosity signal is unstable, and the stability of measurement and control is poor. It is the mechanical structure of the torque measuring rotor that makes it difficult to adjust and maintain the zero point on the line at any time, especially for the perception of the viscosity change of the micro-viscous slurry, such as the sizing slurry, and there is no correlation between the viscosity and the concentration of the test, so Suitable for online production testing.
In summary, the online concentration meter and the online concentration meter are still the main equipment for measuring the concentration of the solution. Changsha Chuyi measurement and control professional R & D, production and sales of online concentration measurement and control system. The equipment includes online concentration sensor (Imported from Austria), concentration measurement and control host (controlled by Siemens PLC), high pressure water prism flushing system, etc.
