In the industrial production process, a flue gas scrubber is one of the key equipment to treat flue gas and reduce pollutant emissions. Accurate measurement of liquid level is important to ensure the normal operation of the scrubber and improve the treatment effect. However, the measurement of flue gas scrubber level faces many difficulties, such as high temperature, high humidity, corrosive, and other complex environmental conditions.
In this paper, we will introduce the advantages and challenges of radar level meter in flue gas scrubber level measurement, and analyze its application effect through actual cases.
Flue gas scrubber level measurement has certain difficulties, such as the high-temperature environment: during the operation of the flue gas scrubber, the internal temperature is high, often exceeding 100℃.
This makes it difficult for the traditional liquid level meter to operate stably for a long time, and it is easy to be inaccurate or damaged.
High humidity environment: high humidity inside the scrubber, water vapor diffusion, the level meter signal transmission, and data processing capabilities put forward higher requirements.
Corrosive media: the liquid inside the scrubber may contain corrosive components, which have a certain erosion effect on the materials and structure of the measuring equipment, affecting the accuracy and service life of the equipment.
Fluctuation and foam: the liquid surface fluctuation is large, more foam, the propagation of radar waves is caused by interference, affecting the measurement accuracy.
As a kind of non-contact measuring instrument, the radar level meter has significant advantages in flue gas scrubber level measurement: high-temperature resistance: adopting high-temperature materials, and sealing design, it can work stably in harsh high-temperature environment to ensure the accuracy and reliability of measurement.
Resistant to high humidity: through special signal processing technology, it can effectively overcome the influence of water vapor on radar waves to ensure the accuracy of measurement. Corrosion resistance: the use of corrosion-resistant materials and surface treatment processes to improve the corrosion resistance of the equipment and extend the service life.
Strong anti-interference ability: the radar level meter is not affected by liquid level fluctuation and foam, and can accurately capture the reflected wave and calculate the liquid level height.
The flue gas scrubber of a steel company’s sintering machine uses a radar level meter for liquid level measurement. The internal temperature of the scrubber is up to 120℃, the humidity is high, and the liquid contains corrosive components.
Traditional liquid level meters are difficult to meet the measurement requirements, and the radar level meter successfully overcame these difficulties. After installation and use, the radar level meter operates stably with high measurement accuracy, providing reliable liquid-level data for the enterprise.
Through the real-time monitoring and analysis of these data, the enterprise can adjust the process parameters in time, optimize the washing effect, effectively reduce the emission of pollutants, and improve production efficiency. Radar level meter in the flue gas scrubber level measurement has significant advantages and application value.
In the face of high temperature, high humidity, corrosive, and other complex environmental conditions, radar level meters can provide accurate and reliable level data, for the enterprise production process optimization and control to provide strong support.
