The invention discloses a multi-parameter on-line monitoring system for desulfurization slurry. The outlet of the cyclone separator is communicated with the inlet of the inclined plate sedimentation tank, and the top outlet of the inclined plate sedimentation tank is divided into five channels, wherein the first channel is connected to the first channel. The inlet of the pH measurement flow cell is connected, the second path is connected with the inlet of the second pH measurement flow cell, the third path is connected with the inlet of the first chloride ion measurement flow cell, and the fourth path is connected with the second chloride ion measurement flow cell The inlet of the pool is connected, and the fifth channel is connected with the sewage valve; the first pH electrode is inserted into the first pH measurement flow cell, the second pH electrode is inserted into the second pH measurement flow cell, and the first chloride ion electrode is inserted into the first pH measurement flow cell. In the chloride ion measurement flow cell, the second chloride ion electrode is inserted into the second chloride ion measurement flow cell. The system can realize the simultaneous online monitoring of the density, pH value and chloride ion content of the desulfurization slurry, and does not require manual sampling for measurement. Low cost of measurement. |
