Description

Technical Field

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

[0002] The dry coke quenching process uses inert gas to cool red coke and recover waste heat such as steam or hot water, which is used in other production links such as power generation and heating to improve energy 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 coal slag. These incompletely carbonized substances make the coke powder have certain chemical reactivity and utilization value.

[0003] The temperature of the coke powder discharged from the CDQ coke oven is very high. If it is not cooled in time, the high-temperature coke powder will be easily oxidized by the air, resulting in coke powder loss and safety hazards. Therefore, the coke powder must be cooled quickly. 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.

[0004] With reference to the Chinese patent document with the authorization announcement number CN104152160B, a dry quenching coke powder cooling device is disclosed, which includes a water-cooling sleeve device, the water-cooling sleeve device includes a cylinder and a water-cooling sleeve, the water-cooling sleeve includes an inner sleeve, a spacer and an outer sleeve from the inside to the outside, the bottom end of the inner sleeve is connected by a semicircular ring tube to form a closed cavity, a gap is left between the spacer and the semicircular ring tube for the circulation of cooling water, the upper part of the cylinder is sequentially provided with a first tube sheet, a second tube sheet and a third tube sheet from top to bottom, a first through hole matched with the inner sleeve is opened on the first tube sheet, and the top end of the inner sleeve is connected to the first through hole.

[0005] With respect to the above-mentioned related technologies, coke powder enters the inner sleeve from the primary dust collector through the first through hole on the first tube plate, 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 path for heat transfer to the cooling medium is longer. The coke powder on the outside of the pipeline is closer to the cooling medium, and the heat conduction is smoother, 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 dry quenching coke powder cooling device, aiming to solve the problem of low heat exchange efficiency of coke powder in the prior art.

[0030] Reference Figure 2 The driving mechanism 3 includes a rotation source 31, a second gear 32, a second gear ring 33 and a third gear 34. The rotation source 31 is fixedly mounted on the sealed shell 54. In this embodiment, the rotation source 31 is a motor. In other embodiments, the rotation source 31 can also be a device whose output shaft can realize rotation, such as a hydraulic motor or a rotary cylinder; the second gear 32 is fixedly connected to the driving shaft of the rotation source 31 and is located at the top of the sealed shell 54; a support platform 331 is fixedly connected to the lower part of the inner wall of the cylinder 11, the second gear ring 33 is rotatably connected to the inner wall of the support platform 331, and the second gear ring 33 is meshed with the second gear 32; the third gear 34 is rotatably sleeved on the outer wall of the inner heat exchange tube 121, the third gear 34 is meshed with the second gear ring 33 and the rotating disk 2 is fixedly connected to the top of the third gear 34.

In other embodiments, the number of support rods 21 can be selected according to actual needs; a connecting frame 22 is provided on the lower rotating sleeve of the outer wall of the support rod 21, and a first gear 23 is fixedly connected to the top of the connecting frame 22; a first gear ring 24 is fixedly connected to the inner wall of the outer heat exchange tube 122, and the first gear 23 is meshed with the first gear ring 24; a stirring tube 25 is located outside the support rod 21, and a slider is fixedly connected to the outer wall of the stirring tube 25 271, a slide groove 27 is provided on the first gear 23 and for the slider 271 to slide, and a protective cover 272 fixedly connected to the first gear 23 is provided on the upper part of the slide groove 27 to prevent coke powder from falling in and affecting the work; a shock-absorbing spring 28 is fixedly connected to both sides of the slider 271, and the shock-absorbing spring 28 is fixedly connected to the inner wall of the slide groove 27; the first gear 23, the first gear ring 24 and the connecting frame 22 are also arranged on the upper part of the support rod 21, the difference is that the top of the external heat exchange tube 122 is fixedly connected to the support shell 241, and the first gear ring 24 is fixedly connected to the inner wall of the support shell 241.

[0033] When the coke powder needs to be stirred and dispersed, the rotating disk 2 can cause the first gear 23 to move therewith when it rotates. When the first gear 23 moves, it can cause the stirring tube 25 to move in the discharge cavity 123, thereby stirring the coke powder and allowing the coke powder to better contact with the tube wall to improve the heat exchange efficiency. Under the action of the eccentric block 26 and centrifugal force, the stirring tube 25 can slide relative to the first gear 23, thereby dispersing the coke powder to improve its heat exchange efficiency.

[0034] Reference Figure 3 , Figure 5 and Figure 7 The discharge cavity 123 is provided with an extrusion mechanism 4 for converting large-size coke powder into small-size coke powder, and the extrusion mechanism 4 includes a screen 41, a through hole 42, a powder discharge pipe 43, a push plate 44, a connecting rod 45, a return spring 46 and a baffle 47; the screen 41 is arranged on the outside of the stirring tube 25, and a guide block 411 is fixedly connected to the top of the screen 41. The top of the guide block 411 is inclined to facilitate the movement of large-size coke powder into the through hole 42. The bottom of the screen 41 is fixedly connected to a feed hopper rotatably sleeved on the stirring tube 25. 412, a through hole 42 is opened on the outer wall of the stirring tube 25 and is located in the feed hopper 412, a powder discharge pipe 43 array is connected to the outer wall of the stirring tube 25, a push plate 44 is slidably connected to the powder discharge pipe 43, and the push plate 44 extends out of the powder discharge pipe 43 on the side close to the support rod 21, a connecting rod 45 is fixedly connected to the inner wall of the powder discharge pipe 43, a reset spring 46 is fixedly connected between the push plate 44 and the connecting rod 45, and a baffle 47 is hinged on the discharge port of the powder discharge pipe 43 to reduce the probability of coke powder entering the powder discharge pipe 43.

[0035] When it is necessary to crush large-particle coke powder, the large-particle coke powder remains in the screen 41 under the obstruction of the screen 41, and enters the through hole 42 under the action of the guide block 411. The stirring tube 25 cooperates with the support rod 21 during the movement to extrude the large-particle coke powder, thereby converting the large-particle coke powder into small-particle coke powder to improve the heat exchange efficiency. At the same time, the first gear 23 and the first gear ring 24 cooperate with each other to change the extrusion position of the stirring tube 25 and the support rod 21, which is beneficial to improve the processing efficiency of large-particle coke powder and improve the heat exchange efficiency of the coke powder. With the extrusion of the stirring tube 25 and the support rod 21, the push plate 44 can push the small-particle 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 tube wall.

[0036] The implementation principle of a dry quenching coke powder cooling device according to an embodiment of the present invention is as follows: first, cooling water is introduced into the first liquid inlet pipe 5 and the second liquid inlet pipe 51, and then coke powder is introduced into the feed pipe 52, and the coke powder enters the discharge cavity 123, and then the rotation source 31 is started to drive the second gear 32 to rotate, and the rotation of the second gear 32 drives the second gear ring 33 to rotate, and the rotation of the second gear ring 33 can drive the third gear 34 to rotate, and the rotation of the third gear 34 can drive the rotating disk 2 to rotate, and the rotating disk 2 can drive the stirring tube 25 to rotate when rotating, and at the same time, with the cooperation of the first gear 23 and the first gear ring 24, the first gear 23 is rotated.

[0037] As the coke powder falls, the coke powder with large particles remains in the screen 41 under the action of the screen 41, and the coke powder with small particles falls normally and is stirred and heat-exchanged by the movement of the stirring tube 25. The coke powder with large particles enters between the stirring tube 25 and the support rod 21 through the hole 42, and the stirring tube 25 can move back and forth under the action of the eccentric block 26, the slider 271 and the slide groove 27, so that the coke powder with large particles can be squeezed for heat exchange.

[0038] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of 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 circumstances.
