The invention belongs to the technical field of chemical engineering separation, and provides a natural eutectic solvent and a preparation method and application thereof, the natural eutectic solvent comprises the following components: caprolactam, citric acid and water; wherein the molar ratio of caprolactam to citric acid is (1-4): (1-2); the mass of the water is 20-40% of the sum of the mass of the caprolactam and the mass of the citric acid. By introducing water as a third component, the viscosity of the system is effectively reduced, the mass transfer performance is improved, and the denitrification efficiency is improved. The eutecticevaporate solvent provided by the invention can provide more reaction sites, has relatively strong removal capacity and selectivity on nitrogenous organic matters, and can realize efficient denitrification under mild conditions. The natural deep-eutectic solvent prepared by the preparation method disclosed by the invention is applied to removal of basic nitrides of oil products, and has the advantages of short time consumption and low dosage, namely high removal efficiency.

The application provides a device for collecting condensation of an electric appliance and a preparation method, which comprises a humidity sensing device, a directional transmission part, an enrichment transfer part and a power supply part. The directional transmission part is arranged at a condensation generation position of the electric appliance. The humidity sensing device is connected to one side of the directional transmission part facing the condensation generation position. The enrichment transfer part is connected to the other side of the directional transmission part. The power supply part is connected to the humidity sensing device. When the humidity sensing device senses the condensation generation, the power supply part supplies power to the directional transmission part. The directional transmission part directionally conducts the condensation to the enrichment transfer part under the electric osmosis effect. The device for collecting condensation of an electric appliance and the preparation method provided by the embodiment of the application can directionally collect the condensation generated by the electric appliance, avoid the problems of large volume, high cost and high power consumption caused by the dehumidification mode of a fan or a dehumidifier, and are more widely applied.
