Description

Technical Field

[0001] The present invention relates to the field of wastewater treatment, and in particular to a treatment device and a treatment method for high-salt wastewater. Background Art

[0002] High-salinity wastewater, this term usually refers to wastewater containing a large amount of inorganic salts, such as sodium chloride, sodium sulfate, etc. These wastewaters may come from multiple industries, including chemical, pharmaceutical, seawater desalination and food processing. What is more serious is that these wastewaters may also be mixed with organic matter, heavy metals and various other pollutants. If such high-salinity wastewater is directly discharged into the environment without effective purification, it will cause immeasurable harm to aquatic organisms, drinking water sources and industrial and agricultural production water.

[0003] Evaporation is a process that uses heating to cause the evaporation of water in high-salt wastewater, aiming to achieve effective separation of salt and water. During the evaporation and crystallization process, as the inorganic salts in the wastewater continue to crystallize, part of these crystallized inorganic salts are tightly attached to the surface of the tank, while the other part is suspended inside the wastewater. The inorganic salt crystal layer on the surface of the tank is like a barrier, which greatly hinders the effective transfer of heat. At the same time, as the salt concentration continues to rise, the intermolecular force gradually increases. This phenomenon not only significantly reduces the efficiency of evaporation, but also has a significant impact on the quality of crystallization.

[0004] In the process of treating high-salinity wastewater by evaporation, sufficient stirring is required. Lack of stirring will lead to uneven concentration distribution inside the high-salinity wastewater. Some areas may quickly reach an oversaturated state, causing a large number of crystals to suddenly form, which not only affects the purity of the inorganic salt crystals, but may also make subsequent separation processes (such as filtration or centrifugation) difficult. In the absence of sufficient stirring, it is easy to cause inorganic salt crystals to preferentially deposit on the heating surface or cooling surface, forming the so-called "scaling" phenomenon. These deposits not only reduce the working efficiency of the equipment, but may also shorten the service life of the equipment and increase maintenance costs. When stirring is insufficient, obvious temperature differences may occur inside the solution, especially when an external heating source is used. This temperature gradient will affect the solubility and crystallization kinetics, further affecting product quality and production efficiency. Summary of the invention
