Description

Technical Field

[0001] The present invention relates to the technical field of coke powder cooling, and particularly relates to a coke powder cooling device for coke dry quenching. Background Art

[0002] The coke dry quenching process uses inert gas to cool red coke and recover waste heat such as steam or hot water, and the waste heat is used for other production links such as power generation and heat supply to improve energy utilization efficiency. Coke powder is a fine particle size material separated from dry coke by physical means. Coke powder usually contains some incompletely carbonized substances such as tar and cinder, and these incompletely carbonized substances make coke powder have certain chemical reactivity and utilization value.

[0003] The coke powder discharged from the coke dry quenching furnace is at a very high temperature. If it is not cooled in time, the high-temperature coke powder is easily oxidized by air, resulting in coke powder loss and safety hazards. Therefore, the coke powder must be quickly cooled. The most common cooling method is to exchange heat between the high-temperature coke powder and a cooling medium (such as water or gas). The coke powder can transfer heat to the cooling medium through heat exchange, thereby realizing heat recovery and utilization.

[0004] Referring to the Chinese patent document with the authorized announcement number CN104152160B, a coke powder cooling device for coke dry quenching is disclosed, which includes a water-cooled sleeve device. The water-cooled sleeve device includes a cylinder body and a water-cooled sleeve. The water-cooled sleeve includes an inner sleeve, a spacer sleeve, and an outer sleeve from the inside to the outside in sequence. The bottom end of the inner sleeve is connected through a semi-circular ring pipe to form a sealed cavity. A gap for cooling water to flow through is left between the spacer sleeve and the semi-circular ring pipe. A first tube sheet, a second tube sheet, and a third tube sheet are sequentially arranged from top to bottom in the upper part of the cylinder body. A first through hole adapted to the inner sleeve is opened on the first tube sheet, and the top pipe orifice of the inner sleeve is connected to the first through hole.

[0005] In view of the above related technologies, coke powder enters the inner sleeve through the first through hole on the first tube sheet from the primary dust collector and exchanges heat with the inner wall of the inner sleeve, thereby completing the cooling of the coke powder. However, during the movement of the coke powder in the pipeline, the coke powder at the center of the pipeline is blocked by the surrounding coke powder, and the heat transfer path to the cooling medium is relatively long. The coke powder on the outer side of the pipeline is closer to the cooling medium, and the heat conduction is more smooth, resulting in low heat exchange efficiency of the coke powder at the center of the pipeline. Summary of the Invention

[0006] In view of this, the present invention provides a coke powder cooling device for coke dry quenching, aiming to solve the problem of low heat exchange efficiency of coke powder in the prior art.

[0007] To solve the above technical problems, the present invention provides a coke powder cooling device for dry quenching coke, which includes a frame. A cylinder body is fixedly connected to the top of the frame. A plurality of cooling tube groups are arranged inside the cylinder body. Each cooling tube group includes an inner heat exchange tube and an outer heat exchange tube. The inner heat exchange tube is located inside the outer heat exchange tube and they are coaxially arranged. A blanking cavity is left between the inner heat exchange tube and the outer heat exchange tube. A rotating disk is rotatably connected to the outside of the inner heat exchange tube. A support rod is fixedly connected to the top of the rotating disk. A first gear is rotatably connected to the outside of the support rod through a connecting frame. The first gear meshes with a first toothed ring fixedly connected to the inner wall of the outer heat exchange tube. A stirring tube slidably connected to the first gear is arranged on the outside of the support rod. An eccentric block is fixedly connected to the side wall of the stirring tube. A chute for the stirring tube to slide is formed on the first gear. Damping springs are fixedly connected between both sides of the stirring tube and the side walls of the chute. A driving mechanism for driving the rotating disk to rotate is arranged on the frame.

[0008] By adopting the above technical solution, the cooperation between the rotating disk and the stirring tube can make the stirring tube stir the coke powder in the blanking cavity, so as to stir the coke powder and make the coke powder fully contact with the side walls of the inner heat exchange tube and the outer heat exchange tube. Furthermore, it is beneficial to the heat exchange of the coke powder, speeds up the reduction of the coke powder temperature, and is beneficial to the improvement of the heat exchange efficiency of the coke powder. And the cooperation between the first gear and the first toothed ring can make the stirring rod rotate relatively. The cooperation between the eccentric block and the chute can make the stirring tube slide back and forth in the chute, so that the coke powder near the stirring tube can be vibrated while stirring the coke powder, which is convenient for heat exchange, thus being beneficial to the improvement of the heat exchange efficiency.

[0009] Optionally, an extrusion mechanism is arranged in the blanking cavity, and the extrusion mechanism is used to change large-particle-size coke powder into small-particle-size coke powder.

[0010] By adopting the above technical solution, the setting of the extrusion mechanism can change large-particle-size coke powder into small-particle-size coke powder, which is beneficial to accelerating the dissipation of heat in the large-particle-size coke powder, and thus is beneficial to the improvement of the heat exchange efficiency of the coke powder.

A connecting rod is fixedly connected to the inner wall of the powder outlet pipe. A return spring is fixedly connected between the connecting rod and the push plate. A baffle is hinged to the discharge port of the powder outlet pipe.

[0012] By adopting the above technical solution, due to the setting of the sieve mesh, large-particle-size materials will remain inside the sieve mesh and enter the cavity between the stirring tube and the support rod through the through holes. With the extrusion between the stirring tube and the support rod, the large-particle-size materials can be crushed. And during the self-rotation of the first gear, the extrusion position between the stirring tube and the support rod can be changed, which is beneficial to the extrusion and crushing of large-particle-size coke powder. During the sliding process of the stirring tube, the push plate can be abutted against the support rod, so that the support rod can push the push plate to move, thereby blowing the coke powder into the blanking cavity, facilitating the continuous heat exchange of the crushed coke powder. At the same time, the blown air flow can reduce the adhesion of coke powder on the side walls of the inner heat exchange tube and the outer heat exchange tube, thus reducing the waste of coke powder.

[0013] Optionally, a guiding block for guiding large-particle-size coke powder is fixedly connected to the top of the sieve mesh.

[0014] By adopting the above technical solution, the setting of the guiding block can guide the large-particle-size coke powder, facilitating its entry into the through holes, thereby accelerating the processing speed of the large-particle-size coke powder and being beneficial to the improvement of the heat exchange efficiency of the coke powder.

The multiple blanking cavities can be fed through the feed pipe. Finally, the cooling water is discharged through the first liquid outlet pipe and the second liquid outlet pipe, and the cooled coke powder is collected through the discharge pipe.

[0017] Optionally, the driving mechanism includes a rotating source fixedly installed on the sealing housing. A second gear is fixedly connected to the driving shaft of the rotating source. The second gear meshes with a second toothed ring. The second toothed ring meshes with a third gear. A rotating disk is fixedly connected to the top of the third gear.

[0018] By adopting the above technical solution, the rotating disk can be rotated under the action of gear transmission, facilitating the heat exchange work of the coke powder.

[0019] Optionally, a feed hopper sleeved on the stirring tube is fixedly connected to the bottom of the sieve mesh, and the through hole is located inside the feed hopper.

[0020] By adopting the above technical solution, the feeding hopper is arranged so that the large-particle-size coke powder can first enter the feeding hopper and then enter the stirring tube through the through hole, facilitating its crushing.

[0039] Referring to Figure 2 , the driving mechanism 3 includes a rotating source 31, a second gear 32, a second toothed ring 33 and a third gear 34. The rotating source 31 is fixedly installed on the sealing housing 54. In this embodiment, the rotating source 31 is a motor. In other embodiments, the rotating source 31 can also be a device such as a hydraulic motor or a rotary cylinder whose output shaft can rotate; the second gear 32 is fixedly connected to the driving shaft of the rotating source 31 and is located at the top of the sealing housing 54; a support platform 331 is fixedly connected to the lower part of the inner wall of the cylinder body 11, the second toothed ring 33 is rotatably connected to the inner wall of the support platform 331, and the second toothed ring 33 meshes with the second gear 32; the third gear 34 is rotatably sleeved on the outer side wall of the inner heat exchange tube 121, the third gear 34 meshes with the second toothed ring 33 and the rotating disk 2 is fixedly connected to the top of the third gear 34.

[0041] Referring to Figure 2 , Figure 3 , Figure 5 and Figure 6, the support rod 21 is fixedly connected to the top of the rotating disk 2, and the support rod 21 is located in the blanking cavity 123. In this embodiment, three support rods 21 are provided. In other embodiments, the number of support rods 21 can be selected according to actual needs; a connecting frame 22 is rotatably sleeved on the lower part of the outer side wall of the support rod 21, and a first gear 23 is fixedly connected to the top of the connecting frame 22; a first toothed ring 24 is fixedly connected to the inner side wall of the outer heat exchange tube 122, and the first gear 23 meshes with the first toothed ring 24; the stirring tube 25 is located outside the support rod 21, a slider 271 is fixedly connected to the outer side wall of the stirring tube 25, a chute 27 is formed on the first gear 23 for the slider 271 to slide, and a protective cover 272 fixedly connected to the first gear 23 is provided at the upper part of the chute 27 to prevent coked powder from falling in and affecting the operation; shock-absorbing springs 28 are fixedly connected to both sides of the slider 271, and the shock-absorbing springs 28 are fixedly connected to the inner side wall of the chute 27; the first gear 23, the first toothed ring 24 and the connecting frame 22 are also provided at the upper part of the support rod 21. The difference is that a support shell 241 is fixedly connected to the top of the outer heat exchange tube 122, and the first toothed ring 24 is fixedly connected to the inner wall of the support shell 241.

[0042] When it is necessary to stir and disperse the coked powder, when the rotating disk 2 rotates, the first gear 23 can move along with it. When the first gear 23 moves, the stirring tube 25 can move in the blanking cavity 123, so as to stir the coked powder, make the coked powder better contact with the tube wall, and improve the heat exchange efficiency. And under the action of the eccentric block 26 and the centrifugal force, the stirring tube 25 can slide relative to the first gear 23, so as to disperse the coked powder and improve its heat exchange efficiency.

[0043] Refer to Figure 3 , Figure 5 and Figure 7 , an extrusion mechanism 4 for changing large-particle-size coked powder into small-particle-size coked powder is provided in the blanking cavity 123. The extrusion mechanism 4 includes a sieve mesh 41, a through hole 42, a powder outlet pipe 43, a push plate 44, a connecting rod 45, a return spring 46 and a baffle 47; the sieve mesh 41 is arranged outside the stirring tube 25, a guide block 411 is fixedly connected to the top of the sieve mesh 41, and the top of the guide block 411 is inclined to facilitate the movement of large-particle-size coked powder into the through hole 42. A feed hopper 412 rotatably sleeved on the stirring tube 25 is fixedly connected to the bottom of the sieve mesh 41. The through hole 42 is formed on the outer side wall of the stirring tube 25 and is located in the feed hopper 412. The powder outlet pipes 43 are arrayedly communicated with the outer side wall of the stirring tube 25. The push plate 44 is slidably connected to the powder outlet pipe 43, and the side of the push plate 44 close to the support rod 21 extends out of the powder outlet pipe 43. The connecting rod 45 is fixedly connected to the inner wall of the powder outlet pipe 43. The return spring 46 is fixedly connected between the push plate 44 and the connecting rod 45. The baffle 47 is hinged to the discharge port of the powder outlet pipe 43 to reduce the probability of coked powder entering the powder outlet pipe 43.

[0044] When it is necessary to crush large - sized coke powder, the large - sized coke powder is blocked by the screen 41 and remains inside the screen 41. Under the action of the guiding block 411, it enters the through - hole 42. During the movement of the stirring pipe 25, it can cooperate with the support rod 21 to extrude the large - sized coke powder, so that the large - sized coke powder can be changed into small - sized coke powder, thereby improving the heat - exchange efficiency. At the same time, the first gear 23 and the first toothed ring 24 cooperate with each other to change the extrusion position of the stirring pipe 25 and the support rod 21, which is beneficial to improving the processing efficiency of the large - sized coke powder and thus improving the heat - exchange efficiency of the coke powder. As the stirring pipe 25 and the support rod 21 are extruded, the push plate 44 can push the small - sized coke powder out of the powder outlet pipe 43 and can also blow the coke powder to reduce the adhesion of the coke powder on the pipe wall.

[0045] The implementation principle of the dry - quenched coke powder cooling equipment according to the embodiment of the present invention is as follows: First, cool water is introduced into the first liquid inlet pipe 5 and the second liquid inlet pipe 51. Then, coke powder is introduced into the feed pipe 52, and the coke powder enters the blanking cavity 123. Then, the rotation source 31 is started to drive the second gear 32 to rotate. The rotation of the second gear 32 drives the second toothed ring 33 to rotate. The rotation of the second toothed ring 33 can drive the third gear 34 to rotate. The rotation of the third gear 34 can drive the rotating disk 2 to rotate. When the rotating disk 2 rotates, it can drive the stirring pipe 25 to rotate. At the same time, under the cooperation of the first gear 23 and the first toothed ring 24, the first gear 23 rotates.

[0046] As the coke powder falls, the large - sized coke powder remains inside the screen 41 under the action of the screen 41. The small - sized coke powder falls normally and is stirred and heat - exchanged by the movement of the stirring pipe 25. The large - sized coke powder enters between the stirring pipe 25 and the support rod 21 from the through - hole 42. Under the action of the eccentric block 26, the slider 271 and the sliding groove 27, the stirring pipe 25 can reciprocate, so as to extrude the large - sized coke powder for heat - exchange.

[0047] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0048] The above is the preferred implementation mode of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
