Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to a desulfurization wastewater treatment device. Background Art

[0002] Desulfurization wastewater is mainly the discharge water of the absorption tower during the wet desulfurization of boiler flue gas (limestone / gypsum method). Flocculants need to be added during the treatment of desulfurization wastewater to make the impurities in the desulfurization wastewater form a flocculated state and then precipitate them. However, the existing desulfurization wastewater sedimentation tank needs to be cleaned regularly during use as the sediment accumulates. However, the existing desulfurization wastewater sedimentation tank sedimentation cleaning process requires that all the water in the sedimentation tank be discharged in advance and then the sediment in the sedimentation tank be cleaned, which is extremely inconvenient. For this reason, we propose a desulfurization wastewater treatment device. Utility Model Content

[0025] Working principle of this utility model:

[0026] Refer to the instruction manual Figure 1-3When the utility model is used, the desulfurized wastewater is injected into the sedimentation tank 1 through the wastewater feeding pipe 4. The honeycomb plate 3 provided in the sedimentation tank 1 can quickly stabilize the injected desulfurized wastewater, so that the desulfurized wastewater can be quickly precipitated. The sediment slides into the temporary storage barrel 8 through the inclined plate 6. The sediment in the temporary storage barrel 8 is input into the sewage storage tank 2 for storage through the guide hopper 9 and the feed pipe 10. When the sewage storage tank 2 is full of sediment, only a single valve 11 needs to be closed. The sediment generated in the sedimentation tank 1 will be temporarily stored in the temporary storage barrel 8 and the guide hopper 9, and the remaining sewage storage tanks 2 continue to collect and store sediment, and the water inlet flushing pipe 1 2 is connected to the water pipe through the first pipe joint 14, the first valve 13 is opened, and clean water is input into the sewage storage tank 2.

In the process of cleaning the sediment, there is no need to discharge the desulfurization wastewater in the sedimentation tank 1. The desulfurization wastewater can continue to settle to the bottom in the sedimentation tank 1, and the use effect is good. After the sediment in the sewage storage tank 2 is cleaned, the valve 11 is opened, and the sediment temporarily stored in the temporary storage cylinder 8 and the guide hopper 9 is input into the sewage storage tank 2.
