Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to energy-saving evaporation and concentration equipment for saline wastewater. Background Art

[0002] Salty wastewater mainly comes from chemical plants and the collection and processing of oil and natural gas. It is produced in a wide range of ways and the amount of water is increasing year by year. At present, near-zero emission treatment processes are generally used to treat salty wastewater. Among them, the evaporation concentration unit is a key step in reducing the amount of salty wastewater and recycling it. Due to the presence of scale-forming ions in the salt of the wastewater, the concentration continues to enrich during the continuous evaporation and concentration process, reaching supersaturation, thereby forming salt scale on the heat exchange surface.

[0003] In the patent with the publication number CN214611635U, an energy-saving evaporation and concentration equipment for saline wastewater is proposed, which includes an evaporation chamber, a combustion tail gas emission pipe, a burner, a liquid circulation pump, a blower, an air intake pump, a spray chamber, a spray layer, a demister, a flue gas pipeline, an exhaust gas adsorption device, a saline wastewater feed pump, and a condensing heat exchanger. By reducing the operating temperature of the equipment and changing the heat transfer interface, the supersaturation of the scale-forming ion salt precipitation is greatly increased under low temperature conditions, and the concentration ratio of the liquid is further increased while effectively limiting the generation of scaling and corrosion. Without a fixed heat transfer interface, the chance of the formed scale adhering to the metal surface can also be reduced, thereby reducing the scaling and corrosion of the equipment. Both the combustion evaporation technology and the air moisture evaporation technology can realize the low-temperature evaporation and concentration process under normal pressure conditions. The operating temperature is generally 70~90℃. The gas-liquid direct contact heat exchange and moisture transfer are carried out without a fixed metal heat exchange surface, which reduces the scaling and corrosion risks of the process equipment. However, the following problems still exist in this patent:

[0004] During use of the above-mentioned energy-saving evaporation and concentration equipment for saline wastewater, the distance between the spray and the smoke exhaust chamber is far, and the smoke exhaust pipe is fixed and cannot be adjusted in length as needed, which makes it inconvenient to operate and use the energy-saving evaporation and concentration equipment for saline wastewater.
