Description

Technical Field

[0001] The utility model belongs to the technical field of heavy wash oil treatment, and particularly relates to continuous distillation and water removal equipment for heavy wash oil treatment. Background Art

[0002] Heavy oil wash treatment is a process used in the petroleum or chemical industry to remove impurities, contaminants or unwanted components from petroleum products.

[0003] When existing distillation and dehydration equipment is used to treat heavy washed oil, it is often done by heating the crude oil to evaporate the water contained in it, and condensing the evaporated water vapor into water, and then discharging the cold water to the outside. However, there is often still some crude oil remaining in the evaporated crude oil vapor. Therefore, if it is directly discharged to the outside after condensing into water, it will not only cause waste of crude oil but also pollute the external environment. In addition, after long-term use, the exposed heat dissipation structure is easily adsorbed by external dust on the surface of its heat dissipation structure, thereby affecting its heat dissipation effect. It is also easy to be collided with other foreign objects, thereby damaging the heat dissipation fins.

[0004] Therefore, in order to address the problem that when the above-mentioned distillation dehydration equipment is used to treat heavy washed oil, a single evaporation dehydration treatment is often difficult to efficiently discharge the water in the crude oil, and its heat dissipation structure is easily affected by external dust and foreign matter, a continuous distillation dehydration equipment for heavy washed oil treatment is developed. By adding a reflux circulation structure, an integrated load-bearing structure, a dust-proof and anti-collision structure and an air-cooled heat dissipation structure to the distillation dehydration equipment, the effect of the device on steam dehydration of heavy oil can be greatly improved, and external collisions and dust can be prevented from affecting the normal operation of the device, and its stability during use can also be improved.

[0007] Preferably, the heater installed in the distillation tower can heat and evaporate the heavy oil therein, evaporate the water in the heavy oil into water vapor, and transport it to the cooling pipe through a pipeline.

[0029] See also Figure 5-Figure 6In this embodiment, the heat dissipation assembly includes a dust cover 2, a heat dissipation aluminum plate 17, a heat dissipation fin 16 and a mounting groove 19. The ends of the heat dissipation aluminum plates 17 that are close to each other are provided with an arc groove 18, and the arc groove 18 is adapted to the outer wall of the cooling tube 6. The ends of the heat dissipation aluminum plates 17 that are away from each other are fixedly connected with the heat dissipation fin 16. The ends of the heat dissipation aluminum plates 17 that are away from each other are fixedly connected with the dust cover 2. The front and rear ends of the dust cover 2 are penetrated with mounting grooves 19. When in use, the steam capacity in the cooling tube 6 can be efficiently transferred to the heat dissipation fin 16 through the heat dissipation aluminum plate 17, and the heat dissipation fin 16 dissipates the heat outward. A cooling fan 20 is fixed in the groove 19, and equidistant cooling grooves 21 are provided on both ends of the dust cover 2.

[0030] During operation, the crude oil in the distillation tower 1 is first heated and evaporated by the heater 10, thereby converting the water content of the crude oil into water vapor. The water vapor then flows along the outlet pipe 5 into the cooling pipe 6, where it is condensed into water by the heat dissipation fins 16 and the heat dissipation aluminum plate 17 in conjunction with the heat dissipation fan 20.

[0031] Next, the condensed water is transported to the separation tower 4 through a pipeline, where the separation tower 4 separates the condensed water into oil and water in an upper and lower manner. The water in the upper layer is discharged to the outside through a drain pipe 8, while the residual crude oil in the lower layer is transported back to the distillation tower 1 through a reflux pipe 7 and a reflux pump for multiple cycles and continuous evaporation and water removal.

[0032] Then, after the crude oil is fully dehydrated, the dehydrated crude oil is transported out through the external pipe in the distillation tower 1, and the crude oil residue remaining in the separation tower 4 is transported out through the oil discharge pipe 9;

[0033] During use, the dust cover 2 can block external dust and foreign matter to prevent them from affecting the normal use of the heat dissipation fins 16, and the heat dissipation fan 20 can assist the heat dissipation fins 16 to perform efficient heat dissipation processing to improve the effect of the cooling pipe 6 on condensing hot steam.

[0034] Through the above steps, the heater 10 installed in the distillation tower 1 can heat the water in the heavy oil therein and evaporate it into steam. The cooling pipe 6 cooperates with the heat dissipation component to efficiently cool the steam, so that the steam condenses into liquid and flows into the separation tower 4. The condensed liquid is then separated into oil and water layers by the separation tower 4, and the water in the upper layer is discharged to the outside through the drain pipe 8. The heavy oil in the lower layer will flow into the distillation tower 1 through the reflux pipe 7 for secondary distillation and dehydration, thereby realizing continuous cycle dehydration. This solves the problem that distillation dehydration equipment is often difficult to perform continuous and efficient dehydration processing on heavy oil when used to treat heavy wash oil.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
