Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a sampler for measuring the on-site real-time density of slurry. Background Art

[0002] The density of the slurry in the desulfurization absorption tower needs to be monitored in real time. The current situation is that there is an online density meter at the slurry discharge port, which is associated with the background system. It can observe the slurry density of the on-site absorption tower in real time to supervise the operation of the desulfurization system. This is also one of the important contents of chemical supervision.

[0003] However, there is a problem with the on-site meter for real-time monitoring, which is that the real-time density reporting is inaccurate due to the bubbles mixed in the absorber slurry and the blockage of the absorber slurry pipeline. Therefore, manual sampling is currently arranged, and the absorber slurry sample is poured into a density bottle, and then brought into the laboratory for weighing, and the real-time slurry volume is calculated and compared with the online meter. Usually, the manual analysis data is calibrated with the online density meter every day, and the online density meter is recalibrated if the deviation is large.

[0004] At present, the manual sampling and manual analysis and calculation of the absorption tower slurry density are used as the arbitration method for the density determination of the absorption slurry. However, the current manual determination method still has some defects. Due to the nature of the absorption tower slurry (mud), during the manual sampling and pouring of the sample into the density bottle, the bottom mud in the absorption slurry has a tendency to settle continuously. During the sample pouring process, the upper slurry is easily poured into the density bottle. The sample obtained in this way cannot reflect the density of the absorption tower slurry at the time of sampling in real time (generally too small), resulting in inaccurate chemical supervision results.

[0005] In view of this, the present application proposes a slurry on-site real-time density measurement sampler. Utility Model Content
