Description

Technical Field

[0001] The utility model relates to the technical field of petroleum coke processing, in particular to a desulfurization and purification device for petroleum coke. Background Art

[0002] Petroleum coke is a product obtained by separating heavy and light oils through distillation of crude oil and then thermally cracking the heavy oil. Depending on different production processes and raw materials, there will be certain differences in the appearance of petroleum coke. For example, needle coke usually has a fibrous or needle-like structure. Burning high-sulfur petroleum coke will produce a large amount of sulfur-containing pollutants such as sulfur dioxide. Reducing the sulfur content in petroleum coke can reduce environmental pollution during its use. Therefore, a desulfurization and purification device for petroleum coke is needed for treatment.

[0003] Currently, an existing device (such as the publication number: CN211338812U) discloses a desulfurization and purification device for petroleum coke. This device controls the temperature at the bottom end of the machine body by setting a cooling box in the middle position of the machine body to prevent damage to the machine body caused by high temperature, effectively protecting the bottom end position of the machine body, and is provided with a burner in the furnace box to accelerate heating inside the furnace box, effectively heating the petroleum coke inside the furnace box, thereby improving the operation efficiency;

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: Since different amounts of petroleum coke may be filled inside the desulfurization and purification device during the processing of petroleum coke, when the amount of petroleum coke is lower than the inside of the burner, the heat conduction efficiency is relatively low at this time, and the practicability is insufficient and needs to be improved. Summary of the Utility Model

Flame spraying heating heads are fixedly installed on the side walls of the two transmission blocks. Second through grooves are penetrated and formed in the interiors of the two side plates. Pipes are provided on the side walls of the two flame spraying heating heads. The two pipes extend to the outside through the second through grooves.

[0012] Preferably, side grooves are symmetrically formed on the side walls of the two first through grooves. Side blocks are slidably installed in the interiors of the side grooves. Each side block is fixedly installed with the transmission block.

Embodiment

[0025] As Figure 1 - Figure 4 shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicability of the existing device. The general idea is as follows:

[0026] In view of the problems existing in the prior art, the present utility model provides a petroleum coke desulfurization and purification device, including a base 11;

[0027] A uniform heating mechanism is symmetrically and fixedly installed at the upper end of the base 11;

[0028] The uniform heating mechanism includes side plates 12. First through grooves 13 are respectively penetrated and opened inside the two side plates 12. Lead screws 14 are respectively rotatably installed inside the two first through grooves 13. Transmission blocks 15 are respectively threadedly installed on the circumferential surfaces of the two lead screws 14. Flame-spraying heating heads 16 are respectively fixedly installed on the side walls of the two transmission blocks 15. By rotating the lead screw 14, the lead screw 14 rotates inside the first through groove 13 and engages in a threaded drive with the transmission block 15, causing the transmission block 15 to slide actively within the first through groove 13, driving the flame-spraying heating head 16 to move. Thus, the position of the flame-spraying heating head 16 can be adjusted according to the petroleum coke accumulated inside the desulfurization and purification device body 27, and then uniform heating can be carried out, improving the heating rate and practicability.

[0029] A second through groove 17 is provided through the interior of both side plates 12. A pipe 18 is provided on the side wall of each of the two flame-spraying heating heads 16. The two pipes 18 extend to the outside through the second through groove 17. By providing the second through groove 17, when the flame-spraying heating head 16 moves, it can drive the pipe 18 to move inside the second through groove 17, avoiding phenomena such as entanglement and improving reliability.

[0030] Side grooves 19 are symmetrically provided on the side walls of both first through grooves 13. A side block 21 is slidably installed inside each side groove 19. Each side block 21 is fixedly installed with a transmission block 15. When the transmission block 15 drives the flame-spraying heating head 16 to move, it can drive the side block 21 to slide inside the side groove 19, thereby providing additional limiting and increasing stability.

[0031] A desulfurization and purification device body 27 is provided at the upper end of the base 11. The desulfurization and purification device body 27 is located between the flame-spraying heating heads 16. A feeding unit 22 and a discharge plate 23 are respectively provided on the surface of the desulfurization and purification device body 27. The discharge plate 23 is located below the feeding unit 22. A control unit 24 is provided on the side wall of the base 11. An observation area 25 (the main material of the observation area 25 is composed of silicon carbide. Silicon carbide has high strength and stability at high temperatures, can withstand high temperatures, and is commonly used in high-temperature stoves, semiconductors, and other fields) is provided on the side wall of the desulfurization and purification device body 27 away from the feeding unit 22. A conveying pipe 26 is provided at the upper end of the feeding unit 22. By providing the feeding unit 22 and the discharge plate 23, the taking out and placing of petroleum coke can be completed. At the same time, gases such as hydrogen sulfide generated by processing petroleum coke can be desulfurized subsequently through the conveying pipe 26, and through the observation area 25, the accumulation situation of petroleum coke inside the desulfurization and purification device body 27 can be known.

[0032] Working principle:

[0033] In the first step, during use, the staff can first open the electric control valve of the feeding unit 22 through the control unit 24. Subsequently, the staff can convey the petroleum coke to be processed inside the desulfurization and purification device body 27. After the conveying is completed, at this time, the staff can observe the height of the petroleum coke accumulation inside the feeding unit 22 according to the observation area 25. Subsequently, the staff can rotate the lead screw 14, causing the lead screw 14 to rotate inside the first through groove 13 and engage in a threaded drive with the transmission block 15, causing the transmission block 15 to drive the side blocks 21 to slide inside the first through groove 13 and the side grooves 19 respectively, thereby driving the flame-spraying heating head 16 to move. When the flame-spraying heating head 16 moves, at this time, the flame-spraying heating head 16 will synchronously drive the pipe 18 to move inside the second through groove 17;

[0034] In the second step, when the flame-spraying heating head 16 then moves to the middle position of the overall height of the piled-up petroleum coke, at this time, the staff can stop rotating the lead screw 14. Subsequently, the staff can turn on the gas supply unit so that the gas can enter the interior of the flame-spraying heating head 16 through the pipeline 18 for ignition, thereby completing the heating of the desulfurization and purification device body 27. As a result, gases such as hydrogen sulfide in the petroleum coke can escape and be transported through the conveying pipe 26 into the subsequent desulfurization tower for sulfur treatment. After the processing is completed, at this time, the staff can open the discharge plate 23 to take out the petroleum coke.

[0035] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
