The MPR E-Scan primary brine concentration analyzer for potassium hydroxide plant is an online brine concentration analyzer driven by a microcomputer processor. Due to its split design, the CPU and main circuit board of the instrument are separated from the optical part, making the system more resistant to high temperature and vibration, better stability, more accurate testing, and longer effective service life. It can display the concentration value of the product in real time and transmit it to the system for easy system integration and control.
The MPR E-Scan primary saltwater concentration analyzer is widely used in potassium hydroxide plants. The following is a detailed introduction:
working principleBased on critical angle total reflection measurement technology. LED light passes through a prism and undergoes reflection and refraction at the interface between the prism and the saline solution. When the incident angle is greater than the critical angle, the light refracts into the solution, while when it is less than the critical angle, it reflects back into the prism and is received by the CCD sensor. The refractive index of different concentrations of saltwater varies, and the critical angle also changes accordingly. The CCD sensor calculates the saltwater concentration value based on the changes in the light and dark areas through a microprocessor.
Technical SpecificationsThe measurement range is 0.0-350.0g/L, the resolution can reach ± 1g/L, the temperature resolution is 0.1 ℃, the working temperature range is -20-150 ℃, the pressure bearing capacity is 2MPa, the protection level is NEMA 4X (IP65), the output signal is 4-20mA, and the concentration measurement accuracy is ± 0.1%.
Instrument FeaturesAdopting a split design, the instrument CPU and main circuit board are separated from the optical part, making the system more resistant to high temperatures and vibrations, better stability, more accurate testing, and longer effective service life. At the same time, the analyzer has factory calibration and automatic temperature compensation functions, which can be directly put into use without on-site calibration, improving the convenience of installation and use.
Installation methodThreaded or flange connections can be selected based on the actual pipeline situation, and the sensor can be installed in a suitable position on the saltwater pipeline to ensure that saltwater can flow fully and stably through the sensor measurement area, in order to obtain accurate concentration data. It can also be equipped with an online mechanical brush automatic cleaning device to prevent impurities from coating the window in the pipeline and ensure measurement accuracy.
Application in Potassium Hydroxide PlantIn the production process of potassium hydroxide, saltwater is an important raw material, and its stable concentration is crucial for subsequent production processes. This analyzer can be installed at the overflow point of the salt tank or on the salt water transportation pipeline to monitor the concentration of salt water in real time. When the concentration is abnormal, the data can be transmitted to the control system in a timely manner, so that operators can take corresponding measures to ensure that the salt water concentration is stable within the process requirements, providing a guarantee for the stable production of potassium hydroxide.
