Technical Field

[0001] This invention belongs to the field of lime slurry density detection technology, specifically a detection device suitable for improving the accuracy of SDA slurry pipeline density. Background Technology

[0002] Currently, in the SDA desulfurization process, densitometers are commonly used to monitor and control the density of lime slurry. However, existing densitometers often develop systematic errors during long-term operation due to various reasons (such as wear and contamination), leading to inaccurate slurry density measurements. This not only increases the frequency of spare parts replacement and raises maintenance costs, but more importantly, the error in slurry density directly affects the service life of equipment such as slurry pumps, slurry pipelines, and agitators, thus negatively impacting desulfurization efficiency.

Especially in the complex SDA desulfurization process with significant slurry density variations, existing densitometers often fail to meet practical needs, and are cumbersome to connect to, with internal slurry leakage being a common problem.
