Description

[0002] It is well known that a certain amount of solvent oil is used in the production process of paraffin wax, and because the solvent oil is volatile, it will be discharged together with the high-temperature steam generated by the production of paraffin wax. If the solvent oil is directly discharged into the atmosphere, it will pollute the environment. Therefore, the high-temperature steam containing solvent oil is generally condensed and the solvent oil in the steam is collected. Traditionally, the steam is generally passed into a condenser tube, and the tube wall of the condenser tube is provided with an interlayer, and cooling water is passed into the interlayer. The heat in the steam is taken away by the circulation of the cooling water, so that the solvent oil is cooled into a liquid state and finally flows out along the condenser tube.

[0003] A Chinese patent (CN104296551A) discloses a condensing device for a solvent oil recovery system, which cools the solvent oil vapor by introducing cooling water into the serpentine coil. The solvent oil vapor will condense on the serpentine coil and adhere to it, which will hinder heat exchange and reduce condensation efficiency. Utility Model Content
