Description

Technical Field

[0001] The utility model relates to the technical field of fuel oil production, in particular to a circulating fuel oil distillation tower. Background Art

[0002] Fuel oil is widely used in power generation in power plants, ship boiler fuel, heating furnace fuel, metallurgical furnace and other industrial furnace fuel. Fuel oil is mainly made from petroleum cracking residue oil and straight-run residue oil. It is characterized by high viscosity and contains a lot of non-hydrocarbon compounds, colloids and asphaltene. In the process of processing raw materials, a circulating fuel oil distillation tower will be used.

[0003] The circulating distillation towers currently used for fuel oil all heat the raw materials and utilize their molecular structure to evaporate the raw materials and allow the steam to pass through a pipe that stores cold water and condense into liquid on the pipe wall, thereby completing the refining. The cold water becomes hot water after condensation. This can easily cause a waste of water resources and make it impossible to achieve water recycling. In addition, when discharging heavy oil, the heavy oil is too viscous and can easily clog the pipe during discharge. Utility Model Content

[0025] According to the above technical solution, after passing through the pipe 401, the hot water in the condenser pipe 402 will flow into the heat dissipation chamber 403. Due to the high temperature, the heat transfer copper sheet 404 will expand the air in the airbag 405.
