Description

Technical Field

[0001] The present invention belongs to the field of high-salt wastewater treatment, and more specifically, it is an efficient anti-crystallization high-salt wastewater treatment system. Background Art

[0002] High-salt wastewater mainly comes from industries such as chemical engineering, petroleum, and pharmaceuticals, as well as the concentrated brine generated during seawater desalination. These wastewaters contain high concentrations of salts and other pollutants. If directly discharged without treatment, they will cause serious pollution to the environment, affecting water quality and ecological balance. By treating high-salt wastewater, the salts and other pollutants in the wastewater can be reduced to meet environmental protection standards, thereby protecting the environment. At the same time, high-salt wastewater contains a large amount of salts and other useful components. Through appropriate treatment methods, these resources can be recycled. Moreover, by treating high-salt wastewater, environmental pollution can be reduced, treatment costs can be lowered, and the recycled useful resources can be used in fields such as industrial production and agricultural irrigation to create economic value.

[0003] However, during the treatment of high-salt wastewater, the high-salt wastewater is transported back and forth through pipelines. However, due to the relatively high content of metal salts in the high-salt wastewater, some metal salts may crystallize and precipitate on the inner wall of the transportation pipeline during the transportation of high-salt wastewater, resulting in a narrowing of the inner diameter of the transportation pipeline or even blockage of the transportation pipeline, thereby shortening the operation time of the system. This not only increases the maintenance cost but also affects the treatment efficiency. Summary of the Invention

The length of the electric heating plates is 1 - 1.5 m, and the electric heating plates are arranged at intervals of 1.5 - 2 m.

Through the stirrers, a spiral water flow can be formed in the corresponding high-salt wastewater pipeline to impact the crystalline salts attached to the inner wall of the high-salt wastewater pipeline.

The pipeline flow rate control module includes several corrosion-resistant pressurizing pumps. The corrosion-resistant pressurizing pumps are arranged at intervals of 10 - 13 m. The corrosion-resistant pressurizing pumps can be turned on when the flow rate of the high-salt wastewater in the corresponding pipeline is too low, or the concentration of the high-salt wastewater is too high, or crystalline salts have already been generated, so as to quickly increase the flow rate of the high-salt wastewater, thereby avoiding salt crystallization caused by low flow rate or high concentration of high-salt wastewater. Moreover, increasing the flow rate can also cause high-speed scouring of the inner wall of the high-salt wastewater pipeline where crystalline salts have already been generated, thereby avoiding the occurrence of pipeline blockage.

[0044] After the actual use of the present invention, the situation of blockage in the high-salt wastewater transportation pipeline has never occurred again. Only occasionally, the inner diameter of the high-salt wastewater transportation pipeline becomes narrower, and it can be quickly processed. After six months of use, under the same treatment equipment and treatment efficiency, the high-salt wastewater treatment efficiency has increased by 10% compared with the six months before the present invention was used. Thus, it effectively avoids the blockage of the high-salt wastewater transportation pipeline and improves the high-salt wastewater treatment efficiency.
