Description

Technical Field

[0001] This utility model relates to the field of petroleum processing technology, and more specifically, to petroleum refining and conversion furnace equipment. Background Technology

[0002] The conversion furnace in petroleum refining is a key piece of equipment in the refining process. It is mainly used to convert petroleum lumps into oil products such as gasoline, diesel, or chemical raw materials. The conversion furnace is a major energy-consuming equipment in oilfield production. It usually has a heater installed at the bottom of the furnace body to refine the petroleum lumps through the action of the heater, thereby achieving the effect of converting them into oil products. The design thermal efficiency of existing heating furnaces is generally between 85% and 90%, and the average operating thermal efficiency is around 85%.

[0003] During the use of the converter, due to the height of the furnace body, external lifting equipment is usually used to feed the crushed oil blocks. This feeding method is relatively troublesome and affects the overall efficiency of feeding the oil blocks. Furthermore, it lacks the ability to recover the temperature from the flue gas, resulting in the direct loss of some heat and a waste of resources. Utility Model Content

[0014] 2. By setting up an exhaust pipe, heat exchange hood, heat exchange chamber, and spiral tube, users can inject cooling water into the spiral tube through the water guide pipe.

[0022] In this embodiment, a heat exchange chamber 12 is provided inside the heat exchange shroud 11, and a spiral tube 13 is provided inside the heat exchange chamber 12.

An external connection hole 16 is provided on the external flange 15.

[0023] More specifically, the user can add oil blocks into the feeding cylinder 3 through the feeding pipe 25, and then control the motor 4 to make the rotating shaft 5 drive the spiral blades 6 to rotate. At this time, the spiral blades 6 will drive the oil blocks inside the feeding cylinder 3 to move upward and enter the furnace body 1 through the inclined pipe 7. Subsequently, the heating component 9 can be turned on to heat the oil blocks to achieve the effect of refining and conversion. The flue gas generated during the heating process will enter the exhaust pipe 10. The user can inject cooling water into the spiral tube 13 in advance through the water guide pipe 14. At this time, the cooling water inside the spiral tube 13 will cool the flue gas through the heat exchange hood 11 and absorb the high temperature heat inside the flue gas. At this time, the cooling water will be heated and finally discharged from the water guide pipe 14 at the bottom of the heat exchange hood 11 for easy collection or utilization, so as to achieve the effect of heat recovery and utilization.

[0024] Please see Figure 1 , Figure 2 and Figure 5 As an implementation method for purifying flue gas: the purification component includes a filter box 17.

An exhaust pipe 24 is provided on the outer wall of the water tank 23 at the upper end. A waste discharge pipe 28 is fixedly provided on the outer wall of the water tank 23.

[0025] Specifically, after being cooled, the flue gas enters the filter box 17. At this time, the dust inside the flue gas is filtered through the coarse filter plate, fine filter screen 20 and activated carbon plate 21 in sequence. Then, it enters the water tank 23 through the action of the negative pressure fan 22, so that the flue gas can fully contact the water inside the water tank 23.

[0028] In summary, when using the entire equipment: the user can add oil blocks into the feeding cylinder 3 through the feeding pipe 25, and then control the motor 4 to make the rotating shaft 5 drive the spiral blades 6 to rotate. At this time, the spiral blades 6 will drive the oil blocks inside the feeding cylinder 3 to move upward and enter the furnace body 1 through the inclined pipe 7. Subsequently, the heating component 9 can be turned on to heat the oil blocks to achieve the refining and conversion effect. The flue gas generated during the heating process will enter the exhaust pipe 10. The user can inject cooling water into the spiral tube 13 in advance through the water guide pipe 14. At this time, the spiral tube 13... The cooling water in the heat exchange hood 11 cools the flue gas and absorbs the high-temperature heat inside the flue gas, thus heating the cooling water. Finally, it is discharged from the water pipe 14 at the bottom of the heat exchange hood 11 for easy collection or utilization. After cooling, the flue gas enters the filter box 17. At this time, the dust inside the flue gas is filtered through the coarse filter plate, fine filter screen 20 and activated carbon plate 21 in sequence. Then, it enters the water tank 23 through the negative pressure fan 22 to ensure that the flue gas is in full contact with the water inside the water tank 23. Finally, it is discharged from the exhaust pipe 24 to improve the purification effect of the flue gas.
