Description

Technical Field

[0001] The utility model relates to the technical field of slurry sampling, in particular to a sampling device for slurry concentration detection. Background Art

[0002] The absorption tower is mainly used to treat sulfur-containing waste gas in flue gas. It sprays out the treated slurry through the internal spray structure so that the slurry droplets can fully contact with the waste gas, thereby achieving the desulfurization effect. In order to keep the slurry inside the absorption tower within an appropriate density range, it is necessary to regularly sample and test the slurry in the tower. However, there are still some problems with the existing slurry sampling equipment.

[0003] In the Chinese utility model patent with announcement number CN220136735U, an automatic sampling machine for detecting desulfurization slurry in an absorption tower is disclosed. An outer cylinder is arranged, and a coaxially arranged guide column is fixedly installed on the top of the inner wall of the outer cylinder. The guide column slides through the piston arrangement, and the lower end of the guide column is slidably inserted in the water storage cavity of the inner cylinder. The side wall of the inner cylinder is fixedly installed with nozzles distributed at equal angles to form a flushing structure, so that the high-pressure water in the outer cylinder can push the piston and the inner cylinder to move along the guide column. At this time, the water will flow into the inner cylinder, and the water in the inner cylinder will be sprayed out through multiple nozzles, thereby cleaning the inside of the device.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the device takes samples for slurry concentration detection, some of the sampled slurry will still remain after being discharged, and the remaining slurry needs to be cleaned by washing. However, the water stains after washing will remain in the sampling device, which will affect the accuracy of the slurry concentration detection. Therefore, we propose a sampling device for slurry concentration detection, which is convenient for removing the residual water stains inside the sampling device after cleaning.
