Description

Technical Field

[0001] The invention relates to the technical field of evaporators, in particular to an evaporator used for evaporating wastewater. Background Art

[0002] In industrial production, wastewater treatment is of vital importance. As an effective wastewater treatment equipment, the evaporator plays an important role. It evaporates the wastewater by heating, separates water from pollutants, and realizes the purification and recycling of wastewater. The application of evaporator helps to reduce pollution to the environment, save water resources, and provide strong support for sustainable development.

[0003] The patent application with application number CN202322010604.1 discloses a wastewater evaporator, including a shell with a water inlet and an outlet provided thereon, a heating tube installed at the bottom of the shell, and also includes: a stirring member installed on the shell, and the stirring member is used to stir the wastewater.

[0004] In summary, in the process of wastewater evaporation, since wastewater usually contains various salts and impurities, scaling is easily formed on the inner wall of the evaporator and the heat exchange surface during evaporation.
