Description

Technical Field

[0001] This utility model relates to the technical field of steam soot blower systems, specifically to a device for preventing ash leakage from the wall box of a soot blower. Background Technology

[0002] Steam soot blowers are energy-saving devices that must be used in conjunction with boilers in thermal power plants and other industries to remove ash from the boiler's heating surface in order to improve the boiler's thermal efficiency. They are a type of boiler soot blower.

[0003] Large boiler steam sootblower wall boxes generally adopt negative pressure wall boxes. However, under unstable boiler load or deep peak shaving, unstable furnace pressure can lead to positive pressure situations. Moreover, under the current power market model, the unit frequently increases or decreases load and performs deep peak shaving, which greatly increases the number of times the boiler is under positive pressure. Under positive pressure, the sootblower wall box may leak ash, causing environmental pollution. Utility Model Content

[0004] This utility model provides a device for preventing ash leakage from the sootblower wall box, which solves the problem of ash leakage from the existing large boiler steam sootblower wall box under the current power market model, where the unit frequently increases or decreases load and performs deep peak regulation, and the number of positive pressure times of the boiler increases significantly. Under positive pressure conditions, this causes ash leakage from the sootblower wall box, resulting in environmental pollution.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A device for preventing ash leakage in a sootblower wall box includes a leak-proof device body, an adjusting component, and a filler. One side of the leak-proof device body is mounted on the sootblower wall box by a fixing component. A through hole is opened on the front of the leak-proof device body. The leak-proof device body is sleeved on the sootblower barrel. The adjusting component is arranged around the leak-proof device body. The interior of the leak-proof device body has a cavity, and the filler is filled into the cavity of the leak-proof device body.

[0007] The beneficial effects of this utility model are as follows: a leak-proof device body is fitted onto the sootblower barrel and fixed to the sootblower wall box. The filling material inside the leak-proof device body blocks ash leakage from the sootblower wall box, reducing the amount of ash leakage. Under positive boiler pressure, this significantly reduces ash leakage. Furthermore, the gap between the filling material and the sootblower barrel can be adjusted using an adjusting component to prevent the sootblower from jamming due to excessive tightness or poor ash-proofing effect due to excessive looseness. This effectively avoids ash leakage under positive boiler pressure, preventing environmental pollution.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the filler can be detachably filled into the cavity of the leak-proof device body.

[0010] The advantages of adopting the above-mentioned further solution are that the filler can be detachably filled into the cavity of the leak-proof device body and can be replaced at any time. It has the characteristics of simple disassembly and assembly, low failure rate, easy maintenance and long service life.

[0011] Furthermore, the filling material includes wool felt and aluminum silicate needled blanket, with the aluminum silicate needled blanket filling the cavity of the leak-proof device body and wool felt filling the periphery of the through holes.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the aluminum silicate needle-punched blanket is filled into the cavity of the leak-proof device body, and wool felt is filled around the through hole, so that the wool felt is in close contact with the soot blower gun barrel, filling the gap between the soot blower gun barrel and the leak-proof device body, blocking the leakage of soot from the soot blower wall box, and reducing the amount of soot leakage from the soot blower wall box.

[0013] Furthermore, the diameter of the through hole is adapted to the diameter of the sootblower barrel.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the diameter of the through hole is adapted to the diameter of the sootblower gun tube, and the sootblower gun tube is installed on the sootblower wall box through the through hole. This device is used to block the soot leakage from the sootblower wall box and reduce the amount of soot leakage from the sootblower wall box.

[0015] Furthermore, the leak-proof device body is a cube structure, a cuboid structure, or a cylindrical structure.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the body of the leak prevention device can be set as a cube structure, a cuboid structure, or a cylindrical structure, which can not only ensure that the body of the leak prevention device is fixed on the sootblower wall box, but also realize the function of the device in blocking ash from the sootblower wall box, thereby reducing the amount of ash leakage from the sootblower wall box, effectively preventing ash leakage under positive pressure of the boiler, and avoiding environmental pollution.

[0017] Furthermore, the adjusting element is an adjusting bolt, and there are multiple adjusting elements, which are respectively movably arranged around the body of the leak-proof device.

[0018] The beneficial effect of adopting the above-mentioned further solution is that multiple adjusting components are respectively moved and set around the body of the leak-proof device, and the gap between the body of the leak-proof device and the sootblower barrel is adjusted by adjusting the amount of movement of the adjusting components.

[0019] Furthermore, the bottom of the adjusting component abuts against the surface of the filler, and the adjusting component adjusts the gap between the soot blower barrel and the filler.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by turning the adjusting component, the bottom of the adjusting component pushes the filler, changing the position of the filler in the internal cavity of the leak-proof device. The adjusting component adjusts the gap between the filler and the sootblower nozzle, preventing the sootblower from getting stuck due to excessive tightness, or from being too loose and resulting in poor ash leakage prevention. This effectively avoids ash leakage under positive pressure conditions in the boiler, preventing environmental pollution.

[0021] Furthermore, it also includes a collection device, one side of which is detachably mounted on the soot blower wall box by a fastener, and the collection device is located below the leak-proof device body. The bottom width of the collection device is greater than the width of the leak-proof device body, and the bottom length of the collection device is greater than the length of the leak-proof device body.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the collection device is set below the body of the leak prevention device to collect the ash that occasionally leaks out of the body of the leak prevention device, and the collection device is cleaned regularly, which effectively avoids ash leakage under positive pressure of the boiler and avoids environmental pollution.

[0023] Furthermore, the bottom surface of the collecting device is inclined, and the side end of the collecting device connected to the soot blower wall box is higher than the other end.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the bottom surface of the collection device is set as an inclined surface, and the side end of the collection device connected to the soot blower wall box is higher than the other end, so that the ash falling to the bottom surface of the collection device falls freely to the lowest end of the collection device and will not form ash layer accumulation.

[0025] Furthermore, the collection device is made of steel structure material.

[0026] The advantage of adopting the above-mentioned further solution is that the collection device is made of steel structure material, which ensures the load-bearing capacity of the collection device. Attached Figure Description

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] Example 1

[0033] like Figure 1-3 As shown, a device for preventing ash leakage in a soot blower wall box includes a leak-proof device body 1, an adjusting member 2, and a filler 3. One side of the leak-proof device body 1 is installed on the soot blower wall box 5 by a fixing member 7. A through hole 11 is opened on the front of the leak-proof device body 1. The leak-proof device body 1 is sleeved on the soot blower barrel 6. The adjusting member 2 is arranged around the leak-proof device body 1. The interior of the leak-proof device body 1 has a cavity, and the filler 3 fills the cavity of the leak-proof device body 1.

[0034] Specifically, a leak-proof device body 1 is fitted onto the sootblower barrel 6 and fixed to the sootblower wall box 5. The filling material 3 inside the leak-proof device body 1 blocks ash leakage from the sootblower wall box 5, reducing the amount of ash leakage. Under positive boiler pressure, this significantly reduces ash leakage. The gap between the filling material 3 and the sootblower barrel 6 is adjusted using the adjusting component 2 to prevent the sootblower from jamming due to excessive tightness or poor leak-proof effect due to excessive looseness. This effectively prevents ash leakage under positive boiler pressure, avoiding environmental pollution.

[0035] like Figure 1-3 As shown, the filler 3 can be detachably filled into the cavity of the leak-proof device body 1.

[0036] Specifically, the filler 3 can be detachably filled into the cavity of the leak-proof device body 1 and can be replaced at any time. It features simple disassembly and assembly, low failure rate, easy maintenance and long service life.

[0037] like Figure 1-3 As shown, the filler 3 includes wool felt 31 and aluminum silicate needled blanket 32. The aluminum silicate needled blanket 32 ​​is filled in the cavity of the leak-proof device body 1, and wool felt 31 is filled around the through hole 11.

[0038] Specifically, the aluminum silicate needle-punched blanket 32 ​​is filled into the cavity of the leak-proof device body 1, and wool felt 31 is filled around the through hole 11 so that the wool felt 31 is in close contact with the soot blower gun 6, filling the gap between the soot blower gun 6 and the leak-proof device body 1, blocking the leakage of soot from the soot blower wall box 5, and reducing the amount of soot leakage from the soot blower wall box 5.

[0039] like Figure 1-3 As shown, the diameter of the through hole 11 is adapted to the diameter of the sootblower barrel 6.

[0040] Specifically, the diameter of the through hole 11 is adapted to the diameter of the soot blower tube 6. The soot blower tube 6 passes through the through hole 11 and is installed on the soot blower wall box 5. This device is used to block the leakage of soot from the soot blower wall box 5 and reduce the amount of soot leakage from the soot blower wall box 5.

[0041] like Figure 1-3 As shown, the main body 1 of the leak-proof device has a cube structure, a cuboid structure, or a cylindrical structure.

[0042] Specifically, the leak-proof device body 1 can be configured as a cube, cuboid, or cylindrical structure, which can ensure that the leak-proof device body 1 is fixed on the sootblower wall box 5, and also realize the function of the device in blocking ash from the sootblower wall box 5, thereby reducing the amount of ash leakage from the sootblower wall box 5, effectively preventing ash leakage under positive pressure of the boiler, and avoiding environmental pollution.

[0043] like Figure 1-3 As shown, the adjusting element 2 is an adjusting bolt, and there are multiple adjusting elements 2, which are respectively moved and arranged around the body 1 of the leak-proof device.

[0044] Specifically, multiple adjusting components 2 are moved and positioned around the body of the leak-proof device 1, and the gap between the body of the leak-proof device 1 and the soot blower barrel 6 is adjusted by adjusting the amount of movement of the adjusting components 2.

[0045] like Figure 1-3 As shown, the bottom of the adjusting member 2 abuts against the surface of the filler 3, and the adjusting member 2 adjusts the gap between the soot blower barrel 6 and the filler 3.

[0046] Specifically, by turning the adjusting component 2, the bottom of the adjusting component 2 pushes the filler 3, changing the position of the filler 3 within the inner cavity of the leak-proof device body 1. The adjusting component 2 adjusts the gap between the filler 3 and the sootblower nozzle 6, preventing the sootblower from getting stuck due to excessive tightness or from being too loose, thus ensuring a good leak-proof effect. This effectively prevents ash leakage under positive pressure conditions in the boiler, avoiding environmental pollution.

[0047] like Figure 1-3As shown, it also includes a collection device 4. One side of the collection device 4 is detachably mounted on the soot blower wall box 5 by a fastener 7. The collection device 4 is located below the leak-proof device body 1. The bottom width of the collection device 4 is greater than the width of the leak-proof device body 1, and the bottom length of the collection device 4 is greater than the length of the leak-proof device body 1.

[0048] Specifically, the collection device 4 is installed below the leak-proof device body 1. The width and length of the bottom surface of the collection device 4 are both greater than the width and length of the leak-proof device body 1, ensuring that any ash falling from the leak-proof device body 1 falls onto the bottom surface of the collection device 4. The collection device 4 is then cleaned regularly to effectively prevent ash leakage under positive pressure conditions in the boiler, thus avoiding environmental pollution.

[0049] like Figure 1-3 As shown, the bottom surface of the collecting device 4 is an inclined surface, and the side end of the collecting device 4 connected to the soot blower wall box 5 is higher than the other end.

[0050] Specifically, the ash layer falling from the leak-proof device body 1 falls freely to the lowest end of the collection device 4, without forming ash layer accumulation.

[0051] like Figure 1-3 As shown, the collection device 4 is made of steel structure material.

[0052] Specifically, the collection device 4 is made of steel structure material to ensure the load-bearing capacity of the collection device 4.

[0053] The beneficial effects of this embodiment are as follows: A leak-proof device body 1 is fitted onto the sootblower barrel 6 and fixed to the sootblower wall box 5. The filling material 3 inside the leak-proof device body 1 blocks the leakage of ash from the sootblower wall box 5. Aluminum silicate needle-punched blanket 32 ​​is filled into the cavity of the leak-proof device body 1, and wool felt 31 is filled around the through hole 11, ensuring close contact between the wool felt 31 and the sootblower barrel 6. This fills the gap between the sootblower barrel 6 and the leak-proof device body 1, blocking the leakage of ash from the sootblower wall box 5 and reducing the amount of ash leakage. Under positive boiler pressure, this significantly reduces ash leakage. Furthermore, the gap between the filling material 3 and the sootblower barrel 6 is adjusted by the adjusting component 2 to prevent the sootblower from jamming due to excessive tightness or poor ash-proofing effect due to excessive looseness. This effectively avoids ash leakage under positive boiler pressure, preventing environmental pollution.

[0054] The working process of this embodiment is as follows: The leak-proof device body 1 is fitted onto the sootblower barrel 6, and one side of the leak-proof device body 1 is fixed to the sootblower wall box 5. Then, aluminum silicate needle-punched blanket 32 ​​is filled into the cavity of the leak-proof device body 1, and wool felt 31 is filled around the through hole 11, ensuring that the wool felt 31 is in close contact with the sootblower barrel 6, filling the gap between the sootblower barrel 6 and the leak-proof device body 1. Next, the adjusting component 2 is turned, and the bottom of the adjusting component 2 pushes the filling material 3, changing the position of the filling material 3 in the cavity of the leak-proof device body 1. The gap between the filling material 3 and the sootblower barrel 6 is adjusted by the adjusting component 2 to prevent the sootblower from jamming due to excessive tightness, or to prevent poor ash leakage due to excessive looseness. This effectively avoids ash leakage under positive pressure conditions in the boiler, preventing environmental pollution.
