Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization and denitration equipment, in particular to a glass fiber reinforced plastic desulfurization tower which is convenient for daily maintenance. Background Art

[0002] The desulfurization tower is a commonly used industrial waste gas treatment equipment, and its internal components need to be inspected and maintained at regular intervals, including repairing the anti-corrosion layer, replacing wearing parts and cleaning the nozzles, etc., and the above-mentioned periodic maintenance operations require the construction of scaffolding, which is time-consuming and requires long periods of downtime. In some cases, when the interval between periodic inspections is not reached, problems may occur in the desulfurization tower and timely daily maintenance is required. This problem is generally caused by damage to wearing parts. The problem can be quickly solved by directly reaching the problem point and replacing the wearing parts. If the scaffolding is still built and repaired according to the periodic maintenance requirements, it will affect the operating efficiency. Utility Model Content

[0003] In order to solve the problem that the above-mentioned desulfurization tower lacks a structure to replace the scaffolding for daily maintenance, the utility model provides a glass fiber reinforced plastic desulfurization tower which is convenient for daily maintenance.

[0004] The technical solution of this utility model is as follows:

[0005] A glass fiber reinforced plastic desulfurization tower convenient for daily maintenance comprises a desulfurization tower body, a ladder is vertically arranged on the inner wall of the desulfurization tower body, and an additional pipe is arranged on one side of the ladder, the additional pipe has the same length direction as the ladder, and the additional pipe is provided with a plurality of stoppers at intervals along the length direction, and the distance between the end of the stopper away from the additional pipe and the ladder can be adjusted;

[0006] The additional tube is provided with a safety rope, and the safety rope comprises a hook sleeved on the outside of the additional tube and a binding rope for use by the staff;

[0007] The maximum distance between the stopper and the ladder is greater than the diameter of the hook.

[0008] By setting up ladders, additional pipes and safety ropes, workers can perform climbing operations in the desulfurization tower in an extremely safe manner, and can reach designated locations and replace wearing parts of the desulfurization tower without setting up scaffolding.

[0009] In order to prevent the hook from falling due to non-human factors, the minimum distance between the end of the stopper away from the additional pipe and the ladder is 0. The stopper can be used to block the hook, thereby preventing the worker from falling from a height.

[0010] The way to achieve the end adjustment of the limiter is that the limiter can rotate, and can only rotate above the horizontal plane where the limiter rotation axis is located. When the limiter is subjected to force, it can support the hook to prevent it from falling continuously.

[0011] In order to prevent the stopper from being unable to reset, the stopper cannot be rotated to a vertical state. Under the action of gravity, the end of the stopper away from the additional pipe will rotate toward one end of the ladder and collide with the ladder.

[0012] As a preferred solution, the rotation angle range of the limiter relative to the horizontal plane is 20°-75°.

[0013] In order to facilitate operations in the desulfurization tower, a plurality of support platforms are arranged at intervals along the vertical direction on the inner wall of the desulfurization tower body.

[0014] In order to facilitate temporary operations of the staff, the ladder is provided with a plurality of inclined holes at intervals along the vertical direction, and the inclined holes can be inserted and fixed with a temporary flat plate. The temporary flat plate can be arranged at different positions according to the needs.

[0015] The temporary plate and the inclined holes are arranged in such a manner that at least two inclined holes are arranged on the same horizontal plane, and the temporary plate includes a plurality of connectors corresponding to the inclined holes, and a horizontal platform plate is fixed to the upper surfaces of the plurality of connectors.

[0016] In order to prevent the temporary plate from falling off the inclined hole, the inclined hole is arranged to be inclined upward.

[0017] In order to facilitate the passage of staff, a notch is provided on one side of the platform board close to the ladder.

[0018] The beneficial effect of the utility model is that the utility model is a glass fiber reinforced plastic desulfurization tower which is convenient for daily maintenance. On the basis of the existing desulfurization tower, a ladder, an additional pipe and a safety rope are added. When there are minor problems such as replacement of wearing parts, daily maintenance can be carried out directly through the ladder, and the setting of the additional pipe and the safety rope can avoid the problem of workers falling after climbing up, which is very safe. In order to facilitate the operation, the above-mentioned ladder can also be provided with a temporary platform to accommodate the workers to temporarily stand and work, and at the position of some wearing parts, a support platform can be directly provided for convenient operation, and the support platform is arranged in a ring shape to facilitate the workers to work around the desulfurization tower.

[0028] like Figure 1 , 2 A FRP desulfurization tower convenient for daily maintenance is shown, including a desulfurization tower body 1, a spray pipe group 11 is arranged above the desulfurization tower body 1, and a ladder 3 is vertically arranged on the inner wall of the desulfurization tower body 1. The highest end of the ladder 3 needs to be higher than the spray pipe group 11 to facilitate the maintenance of the spray pipe group 11. Since the spray pipe groups 11 are arranged in a staggered manner, it is necessary to avoid installing the ladder 3 when it is set.

[0029] Since the desulfurization tower is high, if the worker falls from the ladder 3, it will cause great harm to the worker. For safety reasons, an additional pipe 4 is provided on one side of the ladder 3, and the additional pipe 4 is in the same length direction as the ladder 3. Both ends of the additional pipe 4 are connected to the ends of the ladder 3, and there is a gap between the two to facilitate the subsequent hook 71 to pass through. The additional pipe 4 is provided with multiple limiters 5 at intervals along the length direction. The purpose of the limiter 5 is to block the hook 71. When the worker wears the binding rope 72 and falls, the hook 71 can be blocked by the limiter 5, thereby avoiding continuous falling, and protecting the safety of the worker. It should be noted that the distance between the end of the limiter 5 away from the additional pipe 4 and the ladder 3 can be adjusted, that is, when the worker is climbing, the limiter 5 needs to avoid blocking the hook 71.

[0030] Afterwards, Figure 3As shown, the additional tube 4 is provided with a safety rope 7, and the safety rope 7 includes a hook 71 sleeved on the outside of the additional tube 4 and a binding rope 72 for use by the staff. Before performing daily maintenance work, the staff is required to wear the binding rope 72, and then they can climb up from the ladder 3.

[0031] It should be noted that in the above structure, the maximum distance between the stopper 5 and the ladder 3 is greater than the diameter of the hook 71, that is, the hook 71 can pass through after the end of the stopper 5 is away from the ladder 3, so as to ensure that the staff can perform the climbing work normally. At the same time, in order to prevent the hook 71 from falling down due to unintentional reasons, the minimum distance between the end of the stopper 5 away from the additional pipe 4 and the ladder 3 is 0. The hook 71 can be blocked by the stopper 5, thereby preventing the staff from falling from a height.

[0032] For ease of use, such as Figure 3 As shown, the way to adjust the end of the limiter 5 is that the limiter 5 can rotate, and can only rotate above the horizontal plane where the rotation axis of the limiter 5 is located. To ensure that the limiter 5 can support the hook 71 when it is under force to prevent it from falling continuously. When the staff climbs up, the limiter 5 will not affect the movement of the hook 71, and can directly rotate upward and pass through the hook 71. Otherwise, it will prevent it from falling. If the staff moves downward from a high place, the limiter 5 can be manually adjusted to allow the hook 71 to pass through here. In other words, in the case of non-human accidents, the limiter 5 can protect the staff through the safety rope 7, and under human intervention, it can move up and down normally on the ladder 3, and the staff can only operate one limiter 5 at a time, so accidents can be avoided.

[0033] It should be noted that in order to prevent the limiter 5 from being unable to reset, the limiter 5 cannot be rotated to a vertical state. Under the action of gravity, the end of the limiter 5 away from the additional tube 4 will rotate toward one end of the ladder 3 and collide with the ladder 3. If it can continue to rotate toward the end away from the ladder 3, the limiter 5 will be unable to reset, and will not have a blocking effect on the hook 71. In this case, safety protection will not be provided. For this reason, the rotation stroke of the limiter 5 needs to be limited, and the limiting method is to set a limit groove 51 on the limiter 5, and it will not be able to rotate except for the limit groove 5.

[0034] As a preferred embodiment, the rotation angle range of the stopper 5 relative to the horizontal plane is 20°-75°. The rotation range can accommodate the hook 71 to pass through, and can also ensure rapid reset after rotation and provide a protective effect.

[0035] The above structure can realize that, by setting up the ladder 3, the additional pipe 4 and the safety rope 7, the workers can perform high-altitude operations in the desulfurization tower in an extremely safe manner, and thus can reach the designated position and replace the wearing parts of the desulfurization tower without setting up scaffolding.

[0036] In addition to the above structure, in order to facilitate operations in the desulfurization tower, the inner wall of the desulfurization tower body 1 is provided with multiple support platforms 2 at intervals along the vertical direction. The support platforms 2 are arranged in a ring shape, which is convenient for workers to move to other positions, and the support platforms 2 need to be provided with guardrails.

[0037] Then, as a preferred embodiment, in order to facilitate the temporary operation of the staff at the ladder position, the ladder 3 is provided with a plurality of inclined holes 31 at intervals along the vertical direction, and the inclined holes 31 can be inserted and fixed with the temporary plate 6. The temporary plate 6 can be set at different positions according to the needs, and the staff can work at different positions.

[0038] It should be noted that if Figure 3 , 4 As shown, the temporary plate 6 and the inclined hole 31 are arranged in such a manner that at least two inclined holes 31 are arranged in the same horizontal plane, and the temporary plate 6 includes a plurality of connectors 61 corresponding to the inclined holes 31, and a horizontal platform plate 62 is fixed to the upper surface of the plurality of connectors 61. In addition, in order to prevent the temporary plate 6 from being separated from the inclined hole 31, the inclined hole 31 is arranged to be inclined upward. In other words, the separation direction of the temporary plate 6 relative to the inclined hole is obliquely upward, and this problem will not occur under human intervention, and the safety of the temporary platform can be protected.

[0039] Finally, if Figure 4 As shown, in order to facilitate the passage of workers, a notch is provided on one side of the platform plate 62 close to the ladder 3 .
