Description

Technical Field

[0001] The utility model relates to the technical field of condensation, in particular to high-temperature steam condensation equipment. Background Art

[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.

[0003] Traditionally, steam is passed into the 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 cooling water, so that the solvent oil is cooled into liquid state and finally flows out along the condenser tube. However, due to the small contact area between the condenser tube wall and the steam, the cooling effect is poor. In addition, high-temperature steam is generally accompanied by a high pressure, so the load on the condenser tube is large.

[0004] A Chinese patent (CN104296551A) discloses a condensing device for a solvent oil recovery system, which cools steam through a serpentine coil. However, for a large amount of steam, a longer serpentine coil will also increase the cost of the condensing device.

[0005] Therefore, in summary, the current market needs a condensing device with low cost and good cooling effect. Utility Model Content

[0009] Preferably, the cooling mechanism includes a cooling pipe and multiple cooling plates, wherein the water inlet and outlet ends of the cooling pipe are correspondingly located outside the box, the tube body of the cooling pipe is correspondingly connected to the multiple cooling plates, the multiple cooling plates are all configured as hollow plates, and the multiple cooling plates are evenly arranged in the vertical direction.

[0010] Preferably, the cooling plate is provided with a bend, and the bent end is placed horizontally, and the angle between the inclined end and the horizontal bent end is set to 100-120°.

[0011] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:
