Description

Technical Field

[0001] This utility model relates to the field of petroleum coke desulfurization technology after calcination, and in particular to a petroleum coke desulfurization device after calcination. Background Technology

[0002] Desulfurization units after petroleum coke calcination are important environmental protection equipment specifically designed to reduce the sulfur content of calcined petroleum coke. Utilizing advanced desulfurization technology, they effectively remove sulfur from the petroleum coke, reducing environmental pollution. These desulfurization units are widely used in industries such as petrochemicals and metallurgy. In practical applications, desulfurization units after petroleum coke calcination typically employ the following technologies:

[0003] 1. The desulfurization reaction chamber is responsible for carrying out the desulfurization reaction and has the characteristics of high temperature resistance, corrosion resistance and good sealing performance;

[0004] 2. The feeding system can accurately transport the calcined petroleum coke to the desulfurization unit, ensuring continuous production;

[0005] 3. The discharge system is responsible for discharging the desulfurized petroleum coke from the device for subsequent processing and utilization;

[0006] 4. The control system is responsible for monitoring and controlling the entire desulfurization process to ensure stable operation of the equipment.

[0007] Currently, manufacturers have adopted a variety of equipment and methods to achieve efficient desulfurization. Some manufacturers use chemical desulfurization, which involves adding desulfurizing agents to react chemically with the sulfur in petroleum coke. Other manufacturers use physical desulfurization, which uses adsorbents or special filter materials to remove sulfur. Some manufacturers use combined desulfurization, which combines chemical and physical methods to improve the desulfurization effect.

[0008] However, the above-mentioned implementation methods still have the following problems: during the stirring process, the traditional stirring method has limited stirring efficiency, cannot fully mix the materials, and is prone to leaving residues on the inner wall of the stirring tank, affecting the desulfurization effect. In order to address this problem, this application proposes a solution: designing a petroleum coke calcination desulfurization device. This device adopts a unique reverse linkage stirring mode, that is, during the rotation of the stirring rod, it can drive the stirring tank to rotate in the opposite direction, thereby achieving a more efficient and thorough mixing effect, allowing the materials to be perfectly integrated in this dynamic interactive stirring system. At the same time, the cleaning rod is in contact with the inner wall of the stirring tank, and can thoroughly clean the inner wall as it rotates, avoiding material residues and effectively ensuring the desulfurization effect. This desulfurization device is easy to operate, has stable performance, and can meet the needs of different users, providing an efficient and reliable solution for the desulfurization treatment of petroleum coke.

[0009] (a) Technical problems to be solved

[0010] To address the shortcomings of existing technologies, this utility model provides a desulfurization device for petroleum coke after calcination, which solves the problems of limited stirring efficiency, inability to fully mix materials, and easy formation of residues on the inner wall of the mixing tank, thus affecting the desulfurization effect of traditional stirring methods.

[0011] (II) Technical Solution

[0012] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization device for calcined petroleum coke, comprising a vessel body, a stirring tank rotatably connected inside the vessel body, a circular cover fixedly connected to the inner wall of the stirring tank, a vessel lid fixedly connected to the upper surface of the vessel body, a motor and a feed inlet fixedly installed on the upper surface of the vessel lid, a connecting frame fixedly connected to the lower surface of the vessel lid, a set of circular rods fixedly connected to the lower surface of the connecting frame, a gear 1 rotatably connected to the lower surface of each circular rod, a gear 2 fixedly connected to the annular side of the stirring rod, the stirring rod movably sleeved with the circular cover, a set of stirring blades fixedly connected to the annular side of the stirring rod, a connecting pipe and two fixing blocks fixedly connected to the upper surface of the circular cover, the connecting pipe and the two fixing blocks being fixedly connected to the feed inlet and the vessel lid respectively.

[0013] As a preferred embodiment of this utility model, the second gear meshes with the first gear located on the left side of a set of first gears, and the set of first gears meshes with each other.

[0014] As a preferred technical solution of this utility model, the inner wall of the mixing tank is provided with a set of slots, and each set of slots is movably engaged with the right gear in a set of gears.

[0015] As a preferred embodiment of this utility model, a discharge port is provided at the bottom of the vessel body, and an electromagnetic valve is fixedly installed on the surface of the discharge port.

[0016] As a preferred technical solution of this utility model, two fixing rods are fixedly connected to the annular sides of the stirring blades on the upper and lower sides of the set of stirring blades, and two cleaning rods are fixedly connected to the back sides of the two pairs of fixing rods respectively, and the two cleaning rods are in contact with the inner wall of the stirring tank.

[0017] (III) Beneficial Effects

[0018] 1. During the rotation of the gear two fixed on the stirring rod, it will drive a set of gear one to rotate simultaneously. The rightmost gear one engages with a set of slots opened on the inner wall of the mixing tank. During its counterclockwise rotation, it will drive the mixing tank to rotate. At this time, the stirring rod drives a set of stirring blades to rotate clockwise and simultaneously drives the mixing tank to rotate counterclockwise, thus generating a more complex flow pattern during the stirring process. This interaction causes the material to be subjected to forces in different directions, thereby enabling more thorough mixing and effectively improving the desulfurization effect.

[0019] 2. As a set of stirring blades rotates, the two pairs of fixed rods on them also rotate. During the rotation of the two pairs of fixed rods, the two cleaning rods will rotate together. The two cleaning rods are in contact with the inner wall of the mixing tank. As they rotate, they will clean the mixture remaining on the inner wall of the mixing tank, which can ensure that more raw materials are mixed and used. After the mixing is completed, the discharge port is opened by controlling the solenoid valve to discharge the mixture, which reduces waste caused by residue. At the same time, it reduces the time and labor required for additional cleaning after mixing. Attached Figure Description

The connecting pipe 10 and the two fixing blocks 11 are fixedly connected to the feed port 4 and the kettle cover 2, respectively. The pretreated petroleum coke and desulfurizing agent are mixed in a certain proportion and fed into the stirring tank 7 through the feed port 4. In the stirring tank 7, by controlling parameters such as temperature, pressure and reaction time, the sulfur in the petroleum coke and the desulfurizing agent undergo a chemical reaction. During the reaction, the mixture of petroleum coke and desulfurizing agent needs to be continuously stirred or fluidized to ensure that the reaction proceeds fully.

[0029] Gear 2 15 meshes with the left-hand gear 14 in a set of gears 14. The set of gears 14 mesh with each other. A set of slots 18 is provided on the inner wall of the mixing tank 7. All slots 18 are movably engaged with the right-hand gear 14 in the set of gears 14. By starting the motor 3, its output shaft will drive the fixed stirring rod 9 to rotate clockwise. During the rotation of the stirring rod 9, it will drive the set of stirring blades 17 fixed on it to stir the mixture. At the same time, the gear 2 15 fixed on the stirring rod 9 will drive the set of gears 14 to rotate simultaneously. The rightmost gear 14 engages with the set of slots 18 in the inner wall of the mixing tank 7. During its counterclockwise rotation, it will drive the mixing tank 7 to rotate. At this time, the stirring rod 9 drives the set of stirring blades 17 to rotate clockwise and simultaneously drives the mixing tank 7 to rotate counterclockwise, thus generating a more complex flow pattern during the stirring process. This interaction causes the material to be subjected to forces in different directions, thereby enabling more thorough mixing and effectively improving the desulfurization effect.

[0030] The bottom of the vessel body 1 is provided with a discharge port 6, and a solenoid valve 5 is fixedly installed on the surface of the discharge port 6. Two fixed rods 16 are fixedly connected to the annular sides of the stirring blades 17 on both the upper and lower sides. Two cleaning rods 19 are fixedly connected to the back of the two pairs of fixed rods 16 respectively. The two cleaning rods 19 are in contact with the inner wall of the mixing tank 7. When the stirring blades 17 rotate, the two pairs of fixed rods 16 fixed on them also rotate. The rotation of the two pairs of fixed rods 16 will drive the two cleaning rods 19 to rotate together. The two cleaning rods 19 are in contact with the inner wall of the mixing tank 7. As they rotate, they will clean the mixture remaining on the inner wall of the mixing tank 7, which can ensure that more raw materials are mixed and used. After the mixing is completed, the discharge port 6 is opened by controlling the solenoid valve 5 to discharge the mixture, which reduces waste caused by residue and reduces the time and labor required for additional cleaning after mixing.

[0031] Working principle:

[0032] Pretreated petroleum coke and desulfurizing agent are mixed in a certain proportion and fed into the mixing tank 7 through the feed inlet 4. In the mixing tank 7, by controlling parameters such as temperature, pressure, and reaction time, the sulfur in the petroleum coke reacts chemically with the desulfurizing agent. During the reaction, the mixture of petroleum coke and desulfurizing agent needs to be continuously stirred or fluidized to ensure that the reaction proceeds fully. By starting the motor 3, its output shaft drives the fixed stirring rod 9 to rotate clockwise. During the rotation of the stirring rod 9, a set of fixed stirring blades 17 on it will stir the mixture. At the same time, the gear 15 fixed on the stirring rod 9 will drive a set of gears 14 to rotate simultaneously. The rightmost gear 14 engages with a set of slots 18 opened in the inner wall of the mixing tank 7. During its counterclockwise rotation, it will drive the mixing tank 7 to rotate. At this time, the stirring rod... While driving a set of stirring blades 17 to rotate clockwise, the stirring tank 7 will also rotate counterclockwise, thus generating a more complex flow pattern during the stirring process. This interaction causes the materials to be subjected to forces in different directions, thereby enabling more thorough mixing and effectively improving the desulfurization effect. During the rotation of the set of stirring blades 17, the two pairs of fixed rods 16 fixed on them also rotate. During the rotation of the two pairs of fixed rods 16, the two pairs of fixed rods 16 will drive the two cleaning rods 19 to rotate together. The two cleaning rods 19 are in contact with the inner wall of the stirring tank 7. As they rotate, they will clean the mixture remaining on the inner wall of the stirring tank 7, ensuring that more raw materials are mixed and used. After the stirring is completed, the discharge port 6 is opened by controlling the solenoid valve 5 to discharge the mixture, reducing waste caused by residue and reducing the time and labor required for additional cleaning after stirring.
