Description
Technical Field
[0001] This invention relates to the field of rotary reactor burner technology, and more specifically, to a decoking device for an inclined rotary reactor. Background Technology
[0002] In rotary reactor burners, solid fuel combustion easily produces coke deposits inside the burner. The presence of coke can affect the subsequent use of the burner and hinder the ignition of subsequent fuels. Furthermore, severe coke buildup can adhere to the inner walls of the burner, leading to a decline in overall burner performance and increased maintenance costs over time. Summary of the Invention
[0003] The present invention aims to at least partially solve one of the technical problems in the related art.
[0004] Therefore, embodiments of the present invention provide a descaling device for an inclined rotary reactor, which has the advantage of good descaling effect.

[0006] A spherical body having a cavity for holding a descaling agent, the spherical body including a counterweight and a swinging part, the counterweight and the swinging part being arranged opposite to each other along the height direction of the spherical body.
[0007] The spherical body also has a feed hole and a discharge hole. The feed hole is located in the counterweight part and communicates with the cavity so that the decoking agent can be placed in the cavity through the feed hole. The discharge hole is located in the swing part and communicates with the cavity. The diameter of the discharge hole is adapted to the size of the decoking agent. The radial direction of the discharge hole has an angle with the thickness direction of the wall of the spherical body.
[0008] A counterweight is disposed within the cavity and located in the counterweight section. The center of gravity of the desiccant removal device is located below the center of the desiccant removal device in the height direction of the spherical body. The counterweight is adapted to block the feed hole.
[0009] The decoking device for tilted rotary stacks in this embodiment of the invention is able to swing easily due to its low center of gravity, thus facilitating the dispersal of the decoking agent in the spherical body to the outside of the spherical body for removing coke lumps from the burner.
[0010] In addition, the oscillation of the coke removal device can be used to crush the coke blocks, increasing the contact between the coke blocks and the coke removal agent, thereby further improving the coke removal effect.
[0011] Therefore, the descaling device for tilted rotary stacks according to the present invention has the advantage of good descaling effect.
[0012] In some embodiments, the angle between the radial direction of the discharge hole and the thickness direction of the wall of the spherical body is greater than or equal to 0 degrees and less than 90 degrees.

[0015] In some embodiments, the plurality of crushing components are divided into a plurality of crushing component groups, the plurality of crushing component groups are arranged at intervals along the height direction of the spherical body, and each crushing component group includes at least two crushing components arranged circumferentially along the spherical body.
[0016] In some embodiments, the breaking element is annular and is fitted onto the outer circumferential surface of the spherical body.
[0017] In some embodiments, a limiting member is further included, which is disposed in the cavity and connected to the peripheral wall of the cavity. The limiting member is disposed below the top of the counterweight to prevent the counterweight from moving from the counterweight to the swinging part.
[0018] In some embodiments, there are multiple limiting members, which are arranged at circumferential intervals along the spherical body.
[0019] In some embodiments, the limiting member is annular, the outer peripheral surface of the limiting member is connected to the peripheral wall of the cavity, the inner peripheral surface of the limiting member forms a communicating hole, the top of the counterweight passes through the communicating hole, and there is a gap between the inner peripheral surface of the limiting member and the outer peripheral surface of the counterweight.

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0030] like Figure 1 and Figure 2 As shown, the descaling device for tilted rotary stacks according to an embodiment of the present invention includes: a spherical body 1 and a counterweight 3.
[0031] The spherical body 1 has a cavity 11 for placing the descaling agent 100. The spherical body 1 includes a counterweight 12 and a swinging part 13, which are aligned along the height direction of the spherical body 1 (e.g., ...). Figure 1 Arranged relatively vertically (in the vertical direction). Specifically, such as... Figure 1 As shown, the spherical body 1 has a shell 16, and the cavity 11 enclosed by the shell 16 is used to place the descaling agent 100. The swinging part 13 is located above the counterweight part 12.
[0032] The spherical body 1 also has a feed hole 14 and a discharge hole 15. The feed hole 14 is located in the counterweight part 12 and communicates with the cavity 11 so that the descaling agent 100 is placed in the cavity 11 through the feed hole 14. The discharge hole 15 is located in the swing part 13 and communicates with the cavity 11. The diameter of the discharge hole 15 is adapted to the size of the descaling agent 100. The radial direction of the discharge hole 15 has an angle with the thickness direction of the wall surface of the spherical body 1.
[0033] It is understood that the discharge hole 15 has a first end 151 and a second end 152. The first end 151 is the end of the discharge hole 15 adjacent to the cavity 11. That is, there is an angle α between the radial direction of a discharge hole 15 and the direction of the first end 151 of the discharge hole 15 pointing to the outer wall surface of the outer shell 16 of the spherical body 1.
[0034] The counterweight 3 is disposed within the cavity 11 and located at the counterweight section 12. The center of gravity of the coke removal device is located below the center of the coke removal device in the height direction of the spherical body 1. The counterweight 3 is adapted to block the feed hole 14. It can be understood that the counterweight 3 is disposed within the cavity 11 and can move relative to the spherical body 1 within the cavity 11 so that after the coke removal device enters the burner, it can swing in a roly-poly-like manner, thereby compressing the coke blocks in the burner.
[0035] In other words, the decoking device for tilted rotary stacks in this embodiment of the invention is able to swing easily due to its low center of gravity, thus facilitating the dispersion of the decoking agent 100 in the spherical body 1 to the outside of the spherical body 1 for removing coke from the burner.
[0036] In addition, the oscillation of the coke removal device can be used to crush the coke blocks, increasing the contact between the coke blocks and the coke removal agent 100, thereby further improving the coke removal effect.
[0037] Therefore, the descaling device for tilted rotary stacks according to the present invention has the advantage of good descaling effect.
[0038] It should be noted that the spherical body 1 is a quasi-sphere; optionally, the spherical body 1 is an ellipsoidal body 1, or an egg-shaped body. It is understood that, as... Figure 1 As shown, the bottom of the spherical body 1 is a smooth arc so that the combustion-supporting device can achieve a swaying function similar to a roly-poly toy.
[0039] like Figure 2 As shown, the angle α formed by the radial direction of the discharge hole 15 and the thickness direction of the wall of the spherical body 1 is greater than or equal to 0 degrees and less than 90 degrees. Preferably, the angle α formed by the radial direction of the discharge hole 15 and the thickness direction of the wall of the spherical body 1 is greater than or equal to 30 degrees and less than or equal to 60 degrees.
[0040] In other words, the angle between the radial direction of the discharge hole 15 and the thickness direction of the wall of the spherical body 1 can make the radial direction of the discharge hole 15 approach the vertical direction during the swinging process of the spherical body 1, thereby facilitating the discharge of the descaling agent 100 inside the spherical body 1 from the discharge hole 15.
[0041] In some embodiments, there are multiple discharge holes 15, and the multiple discharge holes 15 are arranged at intervals along the circumference of the spherical body 1. Preferably, as shown in the figure... Figure 1 As shown, the multiple discharge holes 15 are divided into multiple groups of discharge holes 15, and the multiple groups of discharge holes 15 are arranged at intervals in the vertical direction. Each group of discharge holes 15 includes at least two discharge holes 15 arranged along the axial direction of the spherical body 1.
[0042] In other words, the more discharge holes 15 there are, the more desiccant 100 can be discharged from the spherical body 1 during the swinging process, thereby improving the desiccant removal efficiency.
[0043] In some embodiments, the decoking device for tilted rotary stacks of the present invention further includes a plurality of crushing elements 4, which are arranged at intervals along the circumference of the spherical body 1. The crushing elements 4 are disposed on the outer circumferential surface of the spherical body 1 and have a tip portion disposed on the side of the crushing element 4 away from the spherical body 1.
[0044] Specifically, such as Figure 1 As shown, the crushing component 4 is connected to the outer shell 16 of the spherical body 1 and extends outward from the spherical body 1. The tip of the crushing component 4 can be needle-shaped or blade-shaped. That is, when the tip is blade-shaped, the tip has a certain width.
[0045] Preferably, the multiple crushing components 4 are divided into multiple crushing component groups, which are arranged at intervals along the vertical direction. Each crushing component group includes at least two crushing components 4 arranged circumferentially along the spherical body 1. This makes it easier for the spherical body 1 to contact the coke during the swinging process, thereby improving the crushing efficiency of the coke. Therefore, multiple layers of crushing component groups are provided on the outer wall surface of the outer shell 16 of the spherical body 1 to improve the crushing efficiency of the coke.
[0046] In other embodiments, the crushing element 4 is annular and is fitted onto the outer circumferential surface of the spherical body 1. It is understood that the crushing element 4 is arranged around the spherical body 1 to crush the solid fuel.
[0047] In some embodiments, the descaling device for tilting rotary stacks of the present invention further includes a limiting member 5, which is disposed in the cavity 11 and connected to the peripheral wall of the cavity 11. The limiting member 5 is disposed below the top of the counterweight 12 to prevent the counterweight 3 from moving from the counterweight 12 to the swinging part 13.
[0048] Specifically, such as Figure 1 As shown, the limiting member 5 is connected to the inner wall of the outer shell 16 of the spherical body 1 and extends inward to the spherical body 1. It can be understood that the limiting member 5 is used to prevent the counterweight 3 from moving from bottom to top, that is, the limiting member 5 can prevent the counterweight 3 from moving from the bottom of the spherical body 1 to the top of the spherical body 1, thereby preventing the center of gravity of the combustion-supporting device from moving from the bottom to the top of the spherical body 1.
[0049] Preferably, there are multiple limiting members 5, and the multiple limiting members 5 are arranged at intervals along the circumference of the spherical body 1.
[0050] It is understandable that multiple limiting members 5 can be arranged around the counterweight 3, that is, the multiple limiting members 5 form a gap at the end away from the spherical body 1, and the top of the counterweight 3 fits in the gap, so as to better restrict the movement of the counterweight 3 and facilitate the addition of descaling agent 100 into the cavity 11 from the feed hole 14.
[0051] In other words, during the swinging process of the spherical body 1, the counterweight 3 can always block the feed hole 14 to prevent the decoking agent 100 in the cavity 11 from being discharged through the feed hole 14.
[0052] In some embodiments, the limiting member 5 is annular, the outer peripheral surface of the limiting member 5 is connected to the peripheral wall surface of the cavity 11, the inner peripheral surface of the limiting member 5 forms a connecting hole, the top of the counterweight 3 passes through the connecting hole, and there is a gap between the inner peripheral surface of the limiting member 5 and the outer peripheral surface of the counterweight 3.
[0053] It is understandable that the connecting hole is located at the center of the limiting member 5, the top of the counterweight 3 passes through the connecting hole, and there is a gap between the inner circumferential surface of the limiting member 5 and the outer circumferential surface of the counterweight 3, which facilitates the movement of the counterweight 3 and also prevents the limiting member 5 from moving from the counterweight part 12 to the top of the spherical body 1.
