Description

Technical Field

[0001] This utility model relates to the field of gas-solid separation equipment technology, and in particular to a coke cyclone separator. Background Technology

[0002] Existing coke cyclone separators include a volute housing, a cylinder, a cone, and an exhaust pipe. The exhaust pipe passes through the top of the volute housing and extends into the cylinder. Gas containing coke enters the volute housing through an inlet extending spirally from the volute housing. The gas flows along the inner wall of the volute housing and is guided to form a rotating vortex. It then flows spirally downwards along the cylinder towards the cone. Under the action of centrifugal force, the coke is thrown against the inner wall of the cylinder. The coke loses inertia and falls along the wall, landing in the dust collection hopper at the bottom of the cone. The treated gas continuously flows towards the center as it descends within the cone, forming a centripetal radial airflow. The exhaust pipe is located at the top of the volute housing, creating a pressure difference with the inside of the separator. This causes the central radial airflow to spiral upwards and enter the exhaust pipe before being discharged. During the spiral ascent, some coke will still enter the exhaust pipe along with the central radial airflow and be discharged. As the gas spirals upwards, some coke will still enter the exhaust pipe and be discharged along with the central radial airflow. The separator has low dust removal efficiency.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

The separation section is located at the lower end of the first section. The second section is located perpendicular to the axial direction of the first section and is located on the rear side of the upper end of the first section.

[0014] A further technical solution is that the connection between the intake section, the separation section, the retraction section and the exhaust section is provided with a chamfered structure.

[0015] A further technical solution is that the dust collection hopper includes a second cylinder, a second cone cylinder, and a third cylinder.

[0017] A further technical solution is that the exhaust pipe also includes a second flared opening, the front side of which is a circular opening and the rear side of which is a square opening, and the front side of which is connected to the exhaust port on the rear side of the exhaust pipe.

[0018] A further technical solution is that a number of ear seats are provided at intervals on the outer side of the first cylinder.

[0019] The beneficial effects of this utility model embodiment are as follows:

[0020] (I) A coke cyclone separator includes a first cylinder, a volute, a first cone, and an exhaust pipe. Gas containing coke enters the volute through an inlet extending spirally from the volute. The gas flows along the inner wall of the volute and is guided to form a rotating vortex. It then flows spirally downwards along the first cylinder toward the cone. Under centrifugal force, the coke is thrown toward the inner wall of the first cylinder. The coke loses its inertia and falls along the wall, landing in the dust collection hopper at the bottom of the first cone. The treated gas continuously flows toward the center during its descent in the first cone, forming a centripetal radial airflow. The exhaust pipe is located at the top of the volute, creating a pressure difference with the inside of the separator. This causes the radial airflow in the center to spiral upwards and enter the exhaust pipe. The inner wall of the exhaust pipe is provided with spiral blades along the exhaust direction. The spiral direction of the spiral blades is opposite to the spiral direction of the gas. The spiral blades generate shear force with the spiral airflow, disrupting the stability of the airflow. The airflow forms an upward micro-turbulence between the blades. The coke collides with the inner wall of the exhaust pipe and the spiral blades, achieving secondary separation within the exhaust pipe and improving the dust removal efficiency of the coke cyclone separator.

[0021] (II) Further, the exhaust pipe includes an intake section, a converging section, a separating section, and an exhaust section. The exhaust section is located at the upper end of the volute casing, with the exhaust port opening at the upper end of the exhaust section, and the lower end of the exhaust section extending into the volute casing. The separating section is located at the lower end of the exhaust section, with an inner diameter larger than that of the exhaust section. Spiral blades are located on the inner wall of the separating section. The converging section is located at the lower end of the separating section, with an inner diameter smaller than that of the exhaust section. The intake section is located at the lower end of the converging section, with an inner diameter equal to that of the exhaust section, and its opening is located at the lower end of the intake section. The inner diameter of the intake section is equal to that of the exhaust section, ensuring a stable airflow velocity before entering the converging section and avoiding excessive pressure differentials that could cause airflow disturbance. The inner diameter of the converging section is smaller than that of the exhaust section, which accelerates the airflow and reduces local static pressure, creating a negative pressure zone that effectively attracts coke particles in the airflow, causing them to separate from the airflow. The inner diameter of the separation section is larger than that of the exhaust section, and the airflow velocity is significantly reduced in this section. The coke particles in the airflow collide with the inner wall of the separation section and the spiral blades, enhancing the separation effect. The spiral blades inside the exhaust pipe generate shear force due to the rotation of the airflow, further disrupting the airflow stability and creating rising micro-turbulence, which strengthens the gas-solid separation effect. The multi-section design of the exhaust pipe optimizes the airflow path, regulates the airflow velocity, and utilizes the rotation and collision effects of the airflow, significantly improving the separation efficiency of coke particles, reducing the amount of coke residue in the gas, and enhancing the overall performance of the separator.

[0022] (III) Furthermore, a dust-blocking hood is installed within the first section. The dust-blocking hood has a conical structure, with its tip pointing downwards. Upon entering the first section, the gas collides with the dust-blocking hood, and some of the coke powder in the airflow settles down after impacting the surface of the hood due to inertia. The downward-pointing tip of the dust-blocking hood helps guide particles in the airflow downwards and promotes particle settling. The gas then flows along the wall of the dust-blocking hood into the second section, effectively reducing the resuspension or escape of particles in the gas and further improving separation efficiency.

[0031] Example:

[0032] Figure 1 This is a schematic diagram of the formal structure of the coke cyclone separator of this utility model. Figure 1 As shown, a coke cyclone separator includes a first cylinder 100, a volute housing 200, a first cone 300, and an exhaust pipe 400.

[0033] Figure 2 This is a top view of the volute casing in the coke cyclone separator of this utility model. Figures 1-2 As shown, the volute housing 200 is connected to the upper end of the first cylinder 100 and communicates with the interior of the first cylinder 100. The front side of the volute housing 200 has a spirally extended air inlet 201, and the air intake direction of the air inlet 201 is perpendicular to the axial direction of the first cylinder 100.

[0034] like Figure 1As shown, a first conical cylinder 300 is connected to the lower end of a first cylindrical cylinder 100 and communicates with the interior of the first cylindrical cylinder 100. A dust collection hopper 500 is connected to the lower end of the first conical cylinder 300. For example, the dust collection hopper 500 includes a second cylindrical cylinder 510, a second conical cylinder 520, and a third cylindrical cylinder 530. The upper end of the second cylindrical cylinder 510 is connected to the outer side of the lower end of the first conical cylinder 300 and communicates with the interior of the first cylindrical cylinder 100. The second conical cylinder 520 is connected to the lower end of the second cylindrical cylinder 510 and communicates with the interior of the second cylindrical cylinder 510. The third cylindrical cylinder 530 is connected to the lower end of the second conical cylinder 520 and communicates with the interior of the second conical cylinder 520. A powder discharge port 501 is provided at the lower end of the third cylindrical cylinder 530.

[0035] like Figure 1 As shown, an exhaust pipe 400 is located at the upper end of the volute housing 200. An opening 402 is provided at the lower end of the exhaust pipe 400, and an exhaust port 401 is provided at the upper end. The lower end of the exhaust pipe 400 passes through the volute housing 200 and extends into the first cylinder 100. A spiral blade 403 is provided on the inner wall of the exhaust pipe 400 along the exhaust direction, and the spiral direction of the spiral blade 403 is opposite to the spiral direction of the gas.

[0036] like Figure 1As shown, the exhaust pipe 400 further includes an intake section 410, a retracting section 420, a separating section 430, and an exhaust section 440. The exhaust section 440 is located at the upper end of the volute housing 200, and an exhaust port 401 is opened at the upper end of the exhaust section 440. The lower end of the exhaust section 440 extends into the volute housing 200. The separating section 430 is located at the lower end of the exhaust section 440, and the inner diameter of the separating section 430 is larger than the inner diameter of the exhaust section 440. A spiral blade 403 is located on the inner wall of the separating section 430. The retracting section 420 is located at the lower end of the separating section 430, and the inner diameter of the retracting section 420 is smaller than the inner diameter of the exhaust section 440. The intake section 410 is located at the lower end of the retracting section 420, and the inner diameter of the intake section 410 is equal to the inner diameter of the exhaust section 440. An opening 402 is opened at the lower end of the intake section 410. For example, the connections between the intake section 410, the separation section 430, the retraction section 420, and the exhaust section 440 are all equipped with chamfered structures. The inner diameter of the intake section 410 is equal to that of the exhaust section 440, ensuring a stable airflow velocity before entering the retraction section 420 and avoiding excessive pressure difference that could cause airflow disturbance. The inner diameter of the retraction section 420 is smaller than that of the exhaust section 440. By accelerating the airflow and reducing local static pressure, a negative pressure zone is formed, effectively attracting coke particles in the airflow and separating them from the airflow. The inner diameter of the separation section 430 is larger than that of the exhaust section 440. The airflow velocity is significantly reduced in this section, and the coke particles in the airflow collide with the inner wall of the separation section 430 and the spiral blades 403, enhancing the separation effect. The chamfered structures at the connections between the intake section 410, the retraction section 420, the separation section 430, and the exhaust section 440 ensure smooth airflow transitions, reducing airflow interference and eddies, and improving flow efficiency and stability. The spiral blades 403 inside the exhaust pipe 400 generate shear force with the rotation of the airflow, further disrupting the stability of the airflow and forming an upward micro-turbulence, which enhances the gas-solid separation effect. The multi-section design of the exhaust pipe 400 optimizes the airflow path, adjusts the airflow speed, and utilizes the rotation and collision effects of the airflow, significantly improving the separation efficiency of coke powder, reducing the residual amount of coke powder in the gas, and enhancing the overall performance of the separator.

[0037] like Figure 1 As shown, the exhaust section 440 further includes a first section 441 and a second section 442. The first section 441 is located at the upper end of the volute housing 200, and its lower end extends into the volute housing 200. The separation section 430 is located at the lower end of the first section 441. The second section 442 is located perpendicular to the axial direction of the first section 441 and is positioned at the rear of the upper end of the first section 441. The exhaust port 401 is located at the rear of the second section 442. The bent structure of the exhaust section 440 allows the airflow to complete the final gas-solid separation process before discharge, preventing coke particles from being directly discharged with the airflow, improving the coke recovery rate, and reducing the space occupied by the exhaust section 440. This optimizes the overall structural design of the equipment and improves its compactness and adaptability.

[0038] Figure 4 This is a top view schematic diagram of the dust hood in the coke cyclone separator of this utility model. Figure 1 and Figure 4 As shown, furthermore, a dust trap 600 is installed within the first section 441. The dust trap 600 has a conical structure, and its tip faces downwards. When gas enters the first section 441, it collides with the dust trap 600. Some of the coke powder in the airflow settles down after impacting the surface of the dust trap 600 due to inertia. The downward-facing tip of the dust trap 600 helps guide particles in the airflow downwards and promotes particle settling. The gas then flows along the wall of the dust trap 600 into the second section 442, effectively reducing the resuspension or escape of particles in the gas and further improving separation efficiency.

[0039] like Figures 1-2 As shown, the volute housing 200 further includes a first flared opening 202. The rear side of the first flared opening 202 is circular, and the front side is square. The rear side of the first flared opening 202 connects to the air inlet 201 on the front side of the volute housing 200. The first flared opening 202 facilitates the uniform expansion of airflow into the volute housing 200, avoiding excessively fast or slow airflow in certain areas. When the gas enters the separation device, it can be more evenly distributed throughout the volute housing 200, improving separation efficiency and preventing efficiency loss caused by unstable local airflow.

[0040] like Figures 1-3 As shown, the exhaust pipe 400 further includes a second flared opening 404. The front side of the second flared opening 404 is circular, and the rear side is square. The front side of the second flared opening 404 connects to the exhaust port 401 at the rear of the exhaust pipe 400. The second flared opening 404 at the exhaust port 401 effectively controls the speed and direction of the airflow, allowing the airflow to leave the exhaust pipe 400 smoothly. This reduces airflow disturbance in the exhaust system, ensuring that the gas can be discharged from the system quickly and stably, thus improving exhaust efficiency.

[0041] like Figures 1-2 As shown, furthermore, the outer side of the first cylinder 100 is provided with a plurality of lugs 700 at intervals. The lugs 700 serve as connection points to firmly fix the first cylinder 100 to other parts or supports of the equipment, ensuring that the entire device does not shift or shake during operation, thereby enhancing the stability of the equipment and avoiding equipment failure or safety hazards caused by vibration or instability.

[0042] In operation, this embodiment is as follows:

[0043] Gas containing coke powder enters the volute housing 200 through the first horn-shaped opening 202. The gas flows along the inner wall of the volute housing 200, guided to form a rotating vortex, and then spirals downwards along the first cylinder 100 towards the cone. Under centrifugal force, the coke powder is thrown against the inner wall of the first cylinder 100, losing inertia and falling along the wall into the second cylinder 510 at the bottom of the first cone 300. The coke powder then falls sequentially along the second cylinder 510, the second cone 520, and the third cylinder 530 to the discharge port 501, achieving a single gas-solid separation. After this separation, the gas continuously flows towards the center as it descends within the first cone 300, forming a centripetal radial airflow. The exhaust pipe 400 is located at the top of the volute housing 200, creating a pressure difference with the inside of the separator, causing the central radial airflow to spiral upwards and enter the intake section 410 through the opening 402. The airflow enters the converging section 420 along the inlet section 410. The inner diameter of the converging section 420 is smaller than that of the inlet section 410, and the airflow velocity increases. The local static pressure in the converging section 420 decreases, forming a negative pressure adsorption zone. This pulls some of the escaping coke powder in the airflow toward the inner wall of the converging section 420, achieving secondary gas-solid separation. The airflow then enters the separation section 430. The inner diameter of the separation section 430 increases, and the airflow velocity drops sharply. Some of the escaping coke powder in the airflow collides with the spiral blades 403, achieving tertiary gas-solid separation. The gas after tertiary gas-solid separation continues to rise and enters the first section 441. The gas impacts the dust hood 600 in the first section 441. Some of the escaping coke powder in the gas falls down after impacting the dust hood 600. The gas enters the second section 442 along the wall of the dust hood 600, achieving quaternary gas-solid separation. The gas after quaternary gas-solid separation is discharged from the second flare 404 and collected.

[0044] In this embodiment, the spiral blades 403 generate shear force with the spiral airflow, which disrupts the stability of the airflow. The airflow forms an upward micro-turbulence between the spiral blades 403. The coke powder collides with the inner wall of the exhaust pipe 400 and the spiral blades 403, realizing secondary separation within the exhaust pipe 400 and improving the powder discharge efficiency of the coke powder cyclone separator.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
