Description

Technical Field

[0001] The invention belongs to the technical field of petroleum coke separation, and in particular relates to a device for separating moisture from petroleum coke before blending. Background Art

[0002] Petroleum coke is a solid carbonaceous material produced by high-temperature heating of heavy residues from the petroleum refining process. It is mainly used in the aluminum industry, electrode manufacturing, and fuel. During the production of petroleum coke, the moisture inside it may lead to incomplete combustion of the petroleum coke, affecting its calorific value, or cause gasification and melting problems during high-temperature treatment, thereby affecting the quality and performance of the final product. Therefore, it is necessary to separate the moisture before blending to prevent the moisture from affecting the combustion performance and physical properties of the petroleum coke.

[0003] Existing moisture separation devices usually have the following technical problems when separating moisture from petroleum coke: during separation, the traditional hot air drying method is usually used to heat the petroleum coke to evaporate the moisture inside it. During this process, the moisture distribution in the petroleum coke is uneven, which leads to incomplete drying or local over-drying during the drying process, thereby reducing the quality of the final product. At the same time, since the contact effect between the hot air and the petroleum coke cannot be guaranteed, the heating effect on the petroleum coke is very limited, thereby reducing the moisture separation efficiency.

DETAILED DESCRIPTION

[0030] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0031] Example: Refer to Figures 1 to 7 , a water separation device before petroleum coke blending, comprising:

[0032] A separation box 1, wherein a partition plate 11 is fixedly connected to the interior of the separation box 1, a separation cylinder 12 is sealed and rotatably connected to the separation plate 11, a centrifugal assembly for separating water from petroleum coke by centrifugal action is provided on the separation cylinder 12, the centrifugal assembly includes a plurality of centrifugal holes 13 provided on the peripheral side wall of the separation cylinder 12, the plurality of centrifugal holes 13 can filter water but cannot filter petroleum coke, a rotating cylinder 14 is coaxially fixedly connected to the inner bottom wall of the separation cylinder 12, a first gear 15 is fixedly connected to the top of the rotating cylinder 14, a motor 16 is provided on the inner top wall of the separation box 1, a second gear 17 is fixedly connected to the output end of the motor 16, and the first gear 15 and the second gear 17 are meshed with each other;

[0033] In actual use, the second gear 17 is driven to rotate by the motor 16, and the first gear 15 further drives the rotating drum 14 and the separation drum 12 to rotate. The water in the petroleum coke is thrown out of the separation drum 12 through the centrifugal hole 13 by the action of centrifugal force, so as to perform preliminary separation of the water in the petroleum coke.

[0034] The flow component 2 is used for driving the petroleum coke to continuously rise and fall through the continuous flow of fluid to ensure uniform distribution of water in the petroleum coke. The flow component 2 includes a flow airbag 21 fixedly connected to the inner bottom wall of the separation cylinder 12. The portion of the separation cylinder 12 extending below the partition plate 11 is fixedly connected to an annular guide box 22. The upper end of the annular guide box 22 is connected to a liquid inlet pipe 23 and a liquid discharge pipe 24. The liquid inlet pipe 23 and the liquid discharge pipe 24 are both connected to the interior of the flow airbag 21. The liquid inlet pipe 23 and the liquid discharge pipe 24 are both provided with a first one-way valve. The flow airbag 21, the annular guide box 22, the liquid inlet pipe 23 and the liquid discharge pipe 24 are filled with a low-viscosity liquid.

[0035] Among them, the low-viscosity liquid is one of water and alcohol. The low-viscosity liquid has the characteristics of low viscosity and easy flow, and is prone to large fluctuations and ups and downs due to external disturbances during the flow process.

[0036] Among them, a feed pipe 3 is fixedly connected to the inner wall of the separation box 1, and the part of the feed pipe 3 located inside the separation box 1 extends to just above the separation cylinder 12. The part of the feed pipe 3 located outside the separation box 1 is provided with a hopper (not marked in the figure), so that the petroleum coke can pass through the hopper into the feed pipe 3 and be further transported to the separation cylinder 12 to ensure the subsequent moisture separation work.

[0037] In view of the problem that the moisture distribution in petroleum coke in the prior art is uneven, which leads to the problem of incomplete drying or local over-drying during the drying process, thereby reducing the quality of the final product, the present invention sets a flow component 2, and during separation, allows the low-viscosity liquid to circulate in the flow airbag 21, the discharge pipe 24, the annular guide box 22 and the liquid inlet pipe 23. Since the low-viscosity liquid has low viscosity and is easy to flow, and is prone to large fluctuations and ups and downs due to external disturbances during the flow process, the low-viscosity liquid can drive the flow airbag 21 to fluctuate continuously during the circulation process, forming a structure similar to water flow, driving the petroleum coke above the flow airbag 21 to fluctuate continuously, making the moisture distribution in the petroleum coke more uniform, avoiding the problem of incomplete drying or local over-drying, and improving the quality of the final product.

[0038] It also includes a first transmission component 4, which is used to drive the annular guide box 22 to rotate synchronously during the rotation of the drum 14, so as to realize the self-circulation flow of the low-viscosity liquid in the flow airbag 21. The first transmission component 4 includes two support rods 41 fixedly connected to the inner wall of the separation box 1, and an annular guide plate 42 is fixedly connected between the two support rods 41. A plurality of trapezoidal protrusion blocks 43 are arranged in a circular array on the annular guide plate 42. A suction groove 44 connected to the outside is provided on the side wall of the annular guide box 22. A piston block 45 is sealed and slidably connected in the suction groove 44. A hinged rod 46 is provided on one side wall of the piston block 45 close to the annular guide plate 42. A guide wheel 47 is hinged on the end of the hinged rod 46 away from the piston block 45. The guide wheel 47 rolls against the annular guide plate 42 and the plurality of trapezoidal protrusion blocks 43.

[0039] It is worth mentioning that the present invention sets up the first transmission component 4. Since the rotating drum 14 is fixedly connected to the separation drum 12, and the separation drum 12 is fixedly connected to the annular guide box 22, during the rotation of the rotating drum 14, the annular guide box 22 can be driven to rotate synchronously, so that under the action of centrifugal force, the piston block 45 always has a tendency to approach the annular guide plate 42. When the trapezoidal protrusion block 43 squeezes and pushes the guide wheel 47, the piston block 45 will be driven away from the annular guide plate 42. When the trapezoidal protrusion block 43 no longer squeezes and pushes the guide wheel 47, the piston block 45 will approach the annular guide plate 42 under the action of centrifugal force. Therefore, through the reciprocating movement of the piston block 45, the low-viscosity liquid in the annular guide box 22 is reciprocatingly transported to the flow airbag 21 through the liquid inlet pipe 23, and the low-viscosity liquid in the flow airbag 21 is reciprocatingly transported back to the annular guide box 22 through the liquid discharge pipe 24, thereby realizing the self-circulating flow of the low-viscosity liquid without the need to set up an additional driving source.

[0040] It also includes a heating component 5, which is used to heat the petroleum coke during centrifugal separation so as to evaporate the moisture in the petroleum coke. The heating component 5 includes an L-shaped rod 51 fixedly connected to the inner bottom wall of the separation box 1, and a guide tube 52 is fixedly connected to the L-shaped rod 51. The upper end of the guide tube 52 is sealed and rotatably connected to the rotating drum 14, and the interior of the guide tube 52 is connected to the interior of the rotating drum 14. A heating box 53 is provided on the inner top wall of the separation box 1, and the top of the rotating drum 14 is connected to the interior of the heating box 53. An infusion tube 54 is connected between the heating box 53 and the guide tube 52. A second one-way valve is provided at a position above the infusion tube 54 and in the guide tube 52. The guide tube 52, the rotating drum 14 and the infusion tube 54 are filled with a liquid with a high thermal conductivity coefficient.

[0041] Among them, the high thermal conductivity liquid is one of silicone oil and fluorinated liquid, which has good thermal conductivity and is widely used in thermal management and cooling systems.

[0042] In view of the problem that the contact effect between hot air and petroleum coke in the prior art cannot be guaranteed, which leads to a very limited heating effect on the petroleum coke and reduces the water separation efficiency, the present invention sets a heating component 5, and when the water in the petroleum coke is separated by centrifugal force, the high thermal conductivity liquid circulates in the guide cylinder 52, the rotating cylinder 14, the heating box 53 and the infusion pipe 54. When the high thermal conductivity liquid flows through the rotating cylinder 14, it has a direct heating effect on the rotating cylinder 14, and the rotating cylinder 14 is in direct contact with the petroleum coke in the separation cylinder 12. At the same time, when the high thermal conductivity liquid flows through the heating box 53, it can be repeatedly heated by the heating box 53, and the heated high thermal conductivity liquid is re-transported to the rotating cylinder 14 through the guide cylinder 52, thereby greatly improving the heating effect of the high thermal conductivity liquid on the petroleum coke, improving the water separation effect, and performing double water separation on the petroleum coke by heating and separation, thereby improving the water separation efficiency.

[0043] It also includes a second transmission assembly 6, which is used to synchronously drive the high thermal conductivity liquid in the rotating drum 14 to flow continuously during separation. The second transmission assembly 6 includes two telescopic rods 61 fixedly connected to the inner wall of the separation box 1, and T-shaped moving blocks 62 are fixedly connected to the two telescopic rods 61. Abutment rods 63 that periodically resist the T-shaped moving blocks 62 are provided on the side walls of the rotating drum 14. A spring 64 is provided between each T-shaped moving block 62 and the inner wall of the separation box 1, and a first hinge seat 65 is provided at the lower end of each T-shaped moving block 62. The inner wall of the guide cylinder 52 is sealingly and slidably connected with a piston plate 66, and the lower end of the piston plate 66 is fixedly connected to an extension rod 67, and the lower end of the extension rod 67 is fixedly connected to a lifting plate 68. Second hinge seats 69 are provided on the two side walls of the lifting plate 68, and connecting rods 610 are hinged between the two first hinge seats 65 and the two second hinge seats 69.

[0044] It should also be noted that the second transmission assembly 6 provided in the present invention can periodically resist the T-shaped moving block 62 through the resisting rod 63 during the rotation of the drum 14. When the resisting rod 63 resists the T-shaped moving block 62, the two T-shaped moving blocks 62 move away from each other, and under the action of the first hinge seat 65, the second hinge seat 69 and the connecting rod 610, the piston plate 66 is driven to move upward in the guide tube 52. When the resisting rod 63 no longer resists the T-shaped moving block 62, the two T-shaped moving blocks 62 approach each other under the action of the spring 64, thereby driving the piston plate 66 to move downward in the guide tube 52. Through the reciprocating vertical displacement of the piston plate 66, the high thermal conductivity liquid in the heating assembly 5 is self-circulated, so that the entire device only needs to be provided with one driving source, which simplifies the operating steps and achieves the purpose of energy saving and efficiency improvement.

[0045] In addition, a refrigerator 7 is provided on the inner top wall of the separation box 1, and a cooling pipe 71 is connected to the output end of the refrigerator 7. The lower end of the cooling pipe 71 is fixedly connected to an annular cooling chamber 72, and an exhaust pipe 73 is connected to the annular cooling chamber 72. The exhaust pipe 73 is connected to the outside of the separation box 1. A plurality of inclined water guide rods 74 are arranged in a circular array on the annular cooling chamber 72. When the high thermal conductivity liquid in the rotating drum 14 heats the petroleum coke, the evaporated water will condense on the side of the water guide rod 74 and slide downward along the water guide rod 74 until it falls on the side of the separation drum 12. The water vapor generated during heating can be guided to prevent the water vapor from dripping back into the separation box 1 and weakening the water separation effect.

[0046] The present invention can be explained by the following operation mode:

[0047] In actual use, the second gear 17 is driven to rotate by the motor 16, and the first gear 15 further drives the rotating drum 14 and the separation drum 12 to rotate, and the water in the petroleum coke is thrown out of the separation drum 12 through the centrifugal hole 13 by the action of centrifugal force, so as to achieve preliminary separation of the water in the petroleum coke;

[0048] During separation, the low-viscosity liquid is made to circulate in the flow airbag 21, the liquid discharge pipe 24, the annular guide box 22 and the liquid inlet pipe 23. Since the low-viscosity liquid is prone to large fluctuations and ups and downs due to external disturbances during the flow process, the low-viscosity liquid is made to drive the flow airbag 21 to fluctuate continuously during the circulation process, forming a structure similar to water flow, driving the petroleum coke above the flow airbag 21 to fluctuate continuously, so that the water distribution in the petroleum coke is more uniform. The process of the circulation of the low-viscosity liquid is as follows:

[0049] During the rotation of the drum 14, the annular guide box 22 is driven to rotate synchronously, so that the piston block 45 always has a tendency to approach the annular guide plate 42 under the action of centrifugal force. When the trapezoidal protrusion block 43 squeezes and pushes the guide wheel 47, the piston block 45 will be driven away from the annular guide plate 42. When the trapezoidal protrusion block 43 no longer squeezes and pushes the guide wheel 47, the piston block 45 will approach the annular guide plate 42 under the action of centrifugal force, so that a suction pump structure is formed through the reciprocating movement of the piston block 45, so as to realize the self-circulating flow of low-viscosity liquid;

[0050] When the water in the petroleum coke is separated by centrifugal force, the high thermal conductivity liquid circulates in the guide tube 52, the rotating drum 14, the heating box 53 and the liquid infusion pipe 54. When the high thermal conductivity liquid flows through the rotating drum 14, it has a direct heating effect on the rotating drum 14, and the rotating drum 14 is in direct contact with the petroleum coke in the separation drum 12. Therefore, the petroleum coke can be fully heated by the high thermal conductivity liquid. At the same time, when the high thermal conductivity liquid flows through the heating box 53, it can be repeatedly heated by the heating box 53, and the heated high thermal conductivity liquid is transported to the rotating drum 14 again through the guide tube 52, which greatly improves the heating effect of the high thermal conductivity liquid on the petroleum coke and the separation effect of the water. The petroleum coke is double separated from the water by heating and separation, and the water separation efficiency is improved. The process of the circulation of the high thermal conductivity liquid is as follows:

[0051] During the rotation of the drum 14, the T-shaped moving block 62 can be periodically resisted by the resisting rod 63. When the resisting rod 63 resists the T-shaped moving block 62, the two T-shaped moving blocks 62 move away from each other. Under the action of the first hinge seat 65, the second hinge seat 69 and the connecting rod 610, the piston plate 66 is driven to move upward in the guide tube 52. When the resisting rod 63 no longer resists the T-shaped moving block 62, the two T-shaped moving blocks 62 approach each other under the action of the spring 64, thereby driving the piston plate 66 to move downward in the guide tube 52. Through the reciprocating vertical displacement of the piston plate 66, the high thermal conductivity liquid in the heating component 5 is self-circulated.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
