In related technologies, a slag discharging device is used to cool the ash slag. As an important component of the slag discharging device, the cylinder assembly directly affects the slag discharging efficiency of the slag discharging device. The poor cooling effect of the cylinder assembly results in low slag discharging efficiency of the slag discharging device, making the slag discharging capacity of the slag discharging device poor under high-load operation.

Detailed implementation manners

[0024] In order to better understand the above technical solution, the technical solution of the embodiment of this application will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of this application are detailed descriptions of the technical solution of the embodiment of this application, rather than limitations on the technical solution of this application. Without conflict, the technical features in the embodiments of this application and the embodiments can be combined with each other.

[0025] The first aspect embodiment of this application provides a cylinder assembly 10, as Figure 1 , Figure 2 and Figure 3 shown. The cylinder assembly 10 includes a cylinder body 100, a partition 200 and a cooling pipeline 300. The cylinder body 100 constructs a cavity. The partition 200 is connected to the inner wall of the cylinder body 100 to divide the cavity into multiple slag discharge chambers 210. A membrane water wall 400 is provided on the wall surface of the cylinder body 100 and the partition 200. The membrane water wall 400 includes a cooling pipe 410. The cooling pipeline 300 is communicated with the cooling pipe 410.

[0026] In this embodiment, the hollow structure of the cylinder body 100 constructs a cavity. The end of the partition 200 is tightly connected to the inner wall of the cylinder body 100, so that the cavity is divided into multiple slag discharge chambers 210. After the ash slag enters the cylinder body 100 along the inlet of the cylinder body 100, the partition 200 shunts the ash slag, so that the ash slag is dispersed and enters multiple slag discharge chambers 210. A flow guiding member is provided in the cylinder body 100. The flow guiding member forms a flow guiding path, so that the ash slag can move along the flow guiding path during the rotation of the cylinder body 100, and then is discharged through the outlet of the cylinder body 100. The partition 200 makes the distribution of the ash slag in the cylinder body 100 more dispersed, which is beneficial to the cooling and transportation of the ash slag, and thus improves the cooling effect and transportation efficiency of the cylinder body 100 on the ash slag.

[0027] The wall surface of the cylinder body 100 and the partition member 200 are provided with a membrane water wall 400. The membrane water wall 400 is a water wall composed of an airtight tube screen formed by splicing and welding fins and cooling tubes 410. The cooling pipeline 300 is communicated with any one of the cooling tubes 410, so that the cooling water in the cooling pipeline 300 can enter the cooling tube 410. The cylinder body 100 and the partition member 200 are cooled through the membrane water wall 400, and then the slag in the multiple slag discharge cavities 210 is cooled, improving the cooling efficiency of the slag in the cylinder body 100. Through the structure of the sectional membrane water wall 400 of the cylinder body 100, the cooling effect and the conveying efficiency of the internal slag are improved, and then the slag discharge efficiency of the slag discharge device is improved. Moreover, due to the strong pressure-bearing capacity of the membrane water wall 400 structure, the structural strength and safety of the cylinder body assembly 10 are improved, and the slag discharge capacity of the cylinder body assembly 10 is improved, enabling the slag discharge device to meet the working intensity of large loads.

[0028] Exemplarily, the wall surface of the cylinder body 100 and the partition member 200 can be composed of the membrane water wall 400. The wall thickness of the cooling tube 410 is 6 mm to 8 mm. The relatively thin wall thickness of the cooling tube 410 results in a small heat transfer resistance, improving the thermal conductivity coefficient of the cooling tube 410, and further improving the cooling effect of the cooling tube 410.

[0029] Exemplarily, the cylinder body assembly 10 further includes an outer cylinder 110. The outer cylinder 110 covers the outer periphery of the cylinder body 100 to provide structural protection for the cylinder body 100.

[0030] In some embodiments provided by the present application, as Figure 2 shown, optionally, the membrane water wall 400 further includes: a first fin 420 and a second fin 430. The first fin 420 and the second fin 430 are respectively connected to both sides of the cooling tube 410, and both the first fin 420 and the second fin 430 extend in a direction away from each other along the radial direction of the cooling tube 410. Among them, the number of the cooling tubes 410 is multiple, and the first fins 420 and the second fins 430 between adjacent cooling tubes 410 are connected.

[0031] In this embodiment, the number of both the fins and the cooling tubes 410 is multiple. The fins include a first fin 420 and a second fin 430. The first fin 420 and the second fin 430 form a symmetrical structure on both sides of the cooling tube 410, and both the first fin 420 and the second fin 430 extend in a direction away from each other along the radial direction of the cooling tube 410. Figure 2 The arrow direction at X is the radial direction of the cooling tube 410. The cooling tube 410 is intercepted along a plane perpendicular to its axis. In the obtained cross-section, both the first fin 420 and the second fin 430 are located on the extension line of the center line of the cooling tube 410.

[0032] When manufacturing the membrane water wall 400, the first fin 420 and the second fin 430 are pre-connected to the cooling tube 410 to form a sub-membrane wall, and then the first fins 420 and the second fins 430 of adjacent sub-membrane walls are connected. The connection method can be welding, so that the sub-membrane walls after bending and forming are connected to form the membrane water wall 400. Through the batch prefabrication of the sub-membrane walls, the installer only needs to make one connection between the first fin 420 and the second fin 430, reducing the installation steps of the membrane water wall 400 and the deformation generated during installation.

[0033] In some embodiments provided by the present application, as Figure 1 shown, optionally, the membrane water wall 400 further includes a first membrane wall 440, and the first membrane wall 440 is arranged on the wall surface of the cylinder 100. The cylinder assembly 10 further includes a cooling plate 500, and the cooling plate 500 is connected to the first membrane wall 440, and the cooling plate 500 extends in a direction away from the first membrane wall 440.

[0034] In this embodiment, the first membrane wall 440 is arranged on the wall surface of the cylinder 100, the cooling plate 500 is connected to the first membrane wall 440, and the cooling plate 500 extends towards the center of the cylinder 100. Figure 1 The arrow direction at Z indicates the extending direction of the cooling tube 410. The cooling plate 500 increases the contact area between the first membrane wall 440 and the ash slag, improving the cooling effect of the first membrane wall 440 on the ash slag. And the cooling plate 500 can lift the ash slag in the cylinder 100, further improving the conveying effect and the temperature reduction effect of the ash slag.

[0035] Exemplarily, the cooling plate 500 extends obliquely towards the center of the cylinder 100, and the oblique direction conforms to the movement direction of the ash slag in the cylinder 100.

[0036] In some embodiments provided by the present application, as Figure 1 shown, optionally, the cylinder assembly 10 further includes a reinforcing rib 600. The number of the cooling plates 500 is multiple, and the multiple cooling plates 500 are arranged along the circumferential direction of the cylinder 100, and adjacent cooling plates 500 are respectively connected to the reinforcing rib 600.

[0037] In this embodiment, the multiple cooling plates 500 are evenly distributed in the circumferential direction of the cylinder 100. Figure 1 The arrow direction at Y indicates the circumferential direction of the cylinder 100. A reinforcing rib 600 is arranged between adjacent cooling plates 500, and both ends of the reinforcing rib 600 are respectively connected to the adjacent cooling plates 500, so that the reinforcing rib 600 is distributed along the circumferential direction of the cylinder 100, improving the radial rigidity of the cylinder 100 and reducing the deformation of the cylinder 100 along the radial direction due to welding and heat.

[0038] Exemplarily, the number of the reinforcing ribs 600 is multiple, and the multiple reinforcing ribs 600 are arranged at intervals along the axial direction of the cylinder body 100. While improving the axial structural strength of the cylinder body 100, the thermal stress and welding stress of the cylinder body 100 can be released through axial free expansion.

[0039] In some embodiments provided by the present application, as Figure 1 shown, optionally, the membrane water wall 400 further includes a second membrane wall 450, and the second membrane wall 450 is arranged on the partition member 200. The cylinder assembly 10 further includes a material lifting plate 700, and the material lifting plate 700 is connected to the second membrane wall 450 and extends in a direction away from the second membrane wall 450.

[0040] In this embodiment, the second membrane wall 450 is arranged on the partition member 200, and the material lifting plate 700 is connected to the second membrane wall 450. Specifically, the material lifting plate 700 is connected to the cooling pipe 410 of the second membrane wall 450 to improve the stability of the material lifting plate 700. The material lifting plate 700 extends in a direction away from the second membrane wall 450, Figure 1 where the arrow direction at W indicates the extending direction of the material lifting plate 700, so that the material lifting plate 700 extends towards the center of the slag discharge cavity 210. During the rotation of the cylinder body 100, the ash slag can roll in the slag discharge cavity 210 following the material lifting plate 700, facilitating the movement of the ash slag towards the outlet of the cylinder body 100, improving the conveying efficiency of the cylinder body 100 for the ash slag, and further improving the slag discharge efficiency of the cylinder assembly 10. And the ash slag dissipates heat during the lifting process, improving the cooling effect of the cylinder body 100 on the ash slag.

[0041] Exemplarily, the extending path of the material lifting plate 700 includes a curve, reducing the resistance of the ash slag to the material lifting plate 700 and improving the material lifting effect of the material lifting plate 700 on the ash slag.

[0042] In some embodiments provided by the present application, as Figure 1 shown, optionally, the number of the material lifting plates 700 is multiple, and the multiple material lifting plates 700 are respectively arranged on both sides of the second membrane wall 450.

[0043] In this embodiment, the material lifting plates 700 are arranged on both sides of the second membrane wall 450, increasing the number of the material lifting plates 700 in the slag discharge cavity 210, improving the material lifting effect of the material lifting plates 700 on the ash slag, and further improving the conveying efficiency and cooling effect of the cylinder assembly 10.

[0044] In some embodiments provided by the present application, as Figure 3 shown, optionally, the cylinder assembly 10 further includes a rotary joint 800, the rotary joint 800 is communicated with the cooling pipeline 300, and the rotary joint 800 is flexibly connected to the cylinder body 100.

[0045] In this embodiment, a cooling water outlet and a cooling water inlet are provided on the rotary joint 800. The rotary joint 800 is communicated with the cooling pipeline 300, so that cooling water can flow through the rotary joint 800 in the cooling pipeline 300. Figure 3 The direction of the arrow in Figure 3 is the flowing direction of the cooling water, thereby cooling the ash residue in the cylinder body 100. The rotary joint 800 and the cylinder body 100 are flexibly connected, enabling the rotary joint 800 to move appropriately relative to the cylinder body 100, thereby reducing the wear of the rotary joint 800 caused by the vibration of the cylinder body 100 and extending the service life of the rotary joint 800.

[0046] In some embodiments provided by the present application, such as Figure 3 As shown, optionally, the cylinder assembly 10 further includes a heat insulation sleeve 900. One end of the heat insulation sleeve 900 is sleeved outside the slag inlet pipe 20, and the other end is communicated with the inlet of the cylinder body 100.

[0047] In this embodiment, both ends of the heat insulation sleeve 900 are respectively connected to the slag inlet pipe 20 and the inlet of the cylinder body 100, so that the slag inlet pipe 20 of the slag discharging device is communicated with the cylinder body 100 through the heat insulation sleeve 900. Since the ash residue discharged from the slag inlet pipe 20 generates a high-temperature thermal shock, the heat insulation sleeve 900 protects the high-temperature ash residue and avoids the heat-receiving surface of the contact pipeline from being cracked or damaged due to the thermal shock.

[0048] Exemplarily, the heat insulation sleeve 900 can be made of a non-metallic heat insulation material.

[0049] In some embodiments provided by the present application, optionally, the cylinder assembly 10 further includes a slag discharging box. The slag discharging box is communicated with the outlet of the cylinder body 100. The slag discharging box is detachably connected to the cylinder body 100, and the slag discharging box is in a negative pressure state.

[0050] In this embodiment, the slag discharging box in a negative pressure state is communicated with the outlet of the cylinder body 100, so that the ash residue discharged from the cylinder body 100 enters the slag discharging box. The slag discharging box is detachably connected to the cylinder body 100, so that the slag discharging box can be detached after being fully loaded to transfer and clean the ash residue in the slag discharging box. The slag discharging box sucks in the ash residue through negative pressure, which can effectively reduce the ash leakage generated by the connection gap between the slag discharging box and the cylinder body 100 and avoid the phenomenon of ash spraying.

[0051] Exemplarily, the slag discharging box and the cylinder body 100 are separated by a static seal. The static seal can be a sealing ring or a sealing sleeve, so that the space inside the slag discharging box is physically isolated from the cylinder body 100, preventing the overflow or leakage of hot ash. The static seal method can adapt to the positive pressure environment inside the cylinder body 100 and the axial movement of the cylinder body 100.

[0052] In some embodiments provided by the present application, optionally, the cylinder assembly 10 further includes: an ash accumulation tank and a return device. The ash accumulation tank is communicated with the outlet of the cylinder 100. One end of the return device is connected to the ash accumulation tank, and the other end is communicated with the cylinder 100.

[0053] In this embodiment, the ash accumulation tank is communicated with the outlet of the cylinder 100. The ash accumulation tank and the cylinder 100 adopt a dynamic seal structure, so that when the high-temperature ash slag in the cylinder 100 overflows, it falls into the ash accumulation tank through a spiral dynamic seal. The leakage of slag discharge from the cylinder 100 is prevented by a combined static and dynamic seal method. The return device connects the ash accumulation tank and the cylinder 100, so that the ash slag in the ash accumulation tank returns to the cylinder 100 through the return device. The return device is arranged above the cylinder 100, and the return of materials is realized without additional power under the drive of gravity. The return angle range is controllable, and thus a dynamic cycle is formed, realizing a true dynamic seal.

[0054] In the second aspect of the embodiments of the present application, a slag discharge device is provided, as Figure 3 shown. The slag discharge device includes a slag inlet pipe 20 and the cylinder assembly 10 provided in any of the above-mentioned first aspect embodiments of the present application. The slag inlet pipe 20 is communicated with the inlet end of the cylinder 100.

[0055] In this embodiment, the slag discharge device can be a slag cooler. The slag inlet pipe 20 is communicated with the inlet end of the cylinder 100, so that the slag discharge enters the cylinder assembly 10 through the slag inlet pipe 20, so that the cylinder assembly 10 cools down and discharges the slag discharge.

[0056] It should be noted that since it includes the cylinder assembly 10 provided in any of the above-mentioned embodiments of the present application, it has all the beneficial technical effects of the above-mentioned cylinder assembly 10. To avoid repetition, it will not be elaborated here.

[0057] In a specific embodiment, the cylinder assembly 10 of the slag cooler adopts a boiler membrane wall and a bunker structure, and has a high slag discharge capacity. At present, the processing capacity of this type of slag cooler applied in power plants has reached about 30 tons at the rated speed, and the slag discharge temperature is less than or equal to 150 °C. And due to the advantages of strong structural pressure-bearing capacity, good safety and no restrictions on the cooling water system of the membrane finned tube (i.e., the membrane water wall 400), it can be applied to CFB (Circulating Fluidized Bed) boilers and cooling water systems of any grade.

[0058] The conveying capacity at the inlet of the cylinder assembly 10 is improved by the material lifting plate 700, and a large amount of ash slag is pushed to the middle of the slag cooler, avoiding the phenomenon of slag overflow due to too high a material layer. The combination of static and dynamic seals and the replacement of the slag discharge box can effectively reduce the ash leakage between gaps. A small amount of overflow ash is collected in the slag discharge box. Since there is negative pressure air in the slag discharge box and the slag discharge box operates in a slightly negative pressure state, a small amount of overflow ash will not cause ash spraying at each seal.
