Description

Technical Field

[0001] The invention relates to the technical field of desulfurization towers, in particular to a desulfurization tower anti-leakage device. Background Art

[0002] The desulfurization tower is an important device for boiler flue gas treatment. The tower body is generally a steel-lined glass clay flake structure, which is built by welding annular steel plates in circles. Due to defects in the welding quality of the welds in the tower and the anti-corrosion quality of the welds, and the fact that the medium in the tower is an extremely corrosive ammonium sulfate solution, which mainly exists in the lower area of ​​the tower, the welds in the lower area of ​​the desulfurization tower often leak. Due to the strong corrosiveness of the leaked medium, the leakage point will expand rapidly, causing a large amount of medium in the tower to leak along the outer tower wall (the leakage point is generally two or three meters away from the bottom of the tower), polluting the environment.

[0003] Since the existing technology does not have a rapid treatment device for desulfurization tower leakage, when the desulfurization tower leaks, in order to ensure the safety of personnel and equipment, the only way to deal with it is to stop the operation of the desulfurization tower, which seriously affects the production progress. At the same time, the treatment time is too long, which will cause environmental protection indicators to exceed the standard. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a desulfurization tower anti-leakage device, comprising:

[0006] a leakage-proof component, comprising an outer pressure plate structure and a sealing member disposed at the bottom of the outer pressure plate structure; and

[0007] The fixing component comprises an internal beam plate and a locking structure arranged on the inner wall of the internal beam plate.

[0008] As a preferred solution of the desulfurization tower anti-leakage device of the present invention, the outer pressure plate structure comprises an arc-shaped plate, and a mounting hole is opened in the middle of the arc-shaped plate.

[0009] As a preferred solution of the desulfurization tower anti-leakage device of the present invention, the sealing member is annular, and the outer diameter of the arc plate is larger than the outer diameter of the sealing member.

[0013] As a preferred solution of the desulfurization tower anti-leakage device of the present invention, the bottom end of the fastening bolt passes through the built-in beam plate, and the top end of the fastening bolt is located above the arc plate.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a desulfurization tower anti-leakage device, comprising:

[0026] The anti-leakage component 100 includes an outer pressure plate structure 101 and a seal 102 disposed at the bottom of the outer pressure plate structure 101. After leakage occurs, the outer pressure plate structure 101 will be fixed to the leakage hole on the outer wall of the desulfurization tower to block the leakage hole from the outside. Figure 1 As shown, k-1 is the outer wall of the desulfurization tower where leakage occurs, k-2 is the leakage hole, the outer pressure plate structure 101 tightly covers the leakage of the outer wall of the desulfurization tower to stop the leakage, and at the same time, the seal 102 is fixed between the outer pressure plate structure 101 and the outer wall of the desulfurization tower. The seal 102 prevents the medium in the tower from continuing to leak from the gap between the outer pressure plate structure 101 and the outer wall of the desulfurization tower, thereby improving the anti-leakage effect; and

[0027] The fixing member 200 includes an internal beam plate 201 and a locking structure 202 arranged on the inner wall of the internal beam plate 201. The internal beam plate 201 is placed into the desulfurization tower through the leakage hole, and the desulfurization tower is connected to the external pressure plate structure 101 by using the locking structure 202. The internal beam plate 201 is fixed inside the desulfurization tower, and the external pressure plate structure 101 is fixed outside the desulfurization tower. The locking structure 202 forms a tensile force, and the external pressure plate structure 101 and the internal beam plate 201 clamp the outer wall of the desulfurization tower from the inside and outside to plug the leak. The fixing structure is simple, the fixing method is convenient, and the plugging time can be saved.

[0028] Specifically, when a leakage hole appears in the desulfurization tower, the external pressure plate structure 101 is fixed to the outside of the desulfurization tower, and a tensile force is formed by the locking structure 202. The external pressure plate structure 101 and the internal beam plate 201 clamp the outer wall of the desulfurization tower from the inside and outside. The external pressure plate structure 101 tightly covers the leakage on the outer wall of the desulfurization tower to stop the leakage. At the same time, the seal 102 is fixed between the external pressure plate structure 101 and the outer wall of the desulfurization tower. The seal 102 prevents the medium in the tower from continuing to leak from the gap between the external pressure plate structure 101 and the outer wall of the desulfurization tower.

[0029] Example 2, reference Figures 1 to 3 , which is the second embodiment of the present invention. Different from the previous embodiment, the external pressure plate structure 101 includes an arc-shaped plate 101a. The arc of the arc-shaped plate 101a is processed to be close to the arc of the outside of the desulfurization tower, and the arc-shaped plate 101a and the outer wall of the desulfurization tower are fitted as much as possible. A mounting hole 101b is opened in the middle of the arc-shaped plate 101a, and the mounting hole 101b is a through hole.

[0030] Furthermore, the seal 102 is annular, and the outer diameter of the arc plate 101a is larger than the outer diameter of the seal 102. When fixed, the arc plate 101a presses the seal 102 between the arc plate 101a and the outer wall of the desulfurization tower. An annular groove 101c is provided at the top of the mounting hole 101b, and the annular groove 101c is concentric with the mounting hole 101b. The arc plate 101a provides an annular groove 101c at the top of the mounting hole 101b, and the annular groove 101c and the mounting hole 101b together form a step hole.

[0031] Furthermore, the locking structure 202 includes a fastening bolt 202a arranged on the inner wall of the mounting hole 101b, and a ring 202b is arranged on the top outer wall of the fastening bolt 202a. The outer diameter of the ring 202b is the same as the inner diameter of the annular groove 101c, and the outer diameter of the fastening bolt 202a is the same as the inner diameter of the mounting hole 101b. The outer wall of the built-in beam plate 201 is provided with a through hole for the fastening bolt 202a to pass through. The bottom end of the fastening bolt 202a passes through the built-in beam plate 201, and the top end of the fastening bolt 202a is fixed to the inner wall of the built-in beam plate 201. Located above the arc plate 101a, a nut 203 is provided at the bottom of the fastening bolt 202a. Preferably, the nut 203 can be fixed to the bottom of the built-in beam plate 201. The fastening bolt 202a is tightened by the fastening bolt 202a and the nut 203 to form a tension between the built-in beam plate 201 and the arc plate 101a. The built-in beam plate 201 and the arc plate 101a clamp the outer wall of the desulfurization tower. Preferably, the built-in beam plate 201 can be processed in various sizes in advance, and the size of the leakage hole that is suddenly broken has been used.

[0032] Specifically, when a leak occurs in the desulfurization tower, the built-in beam plate 201 is placed into the desulfurization tower through the leakage hole, and the arc plate 101a is placed on the outside of the desulfurization tower at a position corresponding to the built-in beam plate 201. The fastening bolts 202a and nuts 203 are used to tighten the fastening bolts 202a to form a tensile force between the built-in beam plate 201 and the arc plate 101a. The built-in beam plate 201 and the arc plate 101a clamp the outer wall of the desulfurization tower, thereby blocking the leakage area and preventing leakage.

[0033] Example 3, reference Figures 1 to 3 , which is the third embodiment of the present invention. Different from the previous embodiment, a gasket 204 is provided on the outer wall of the fastening bolt 202a. The inner diameter of the gasket 204 is the same as the outer diameter of the embedded ring 202b. A sealing filler 205 is provided on the inner wall of the gasket 204. The top of the sealing filler 205 contacts the embedded ring 202b. The bottom of the sealing filler 205 contacts the annular groove 101c. The inner size of the annular groove 101c is the same as the size of the embedded ring 202b. The outer diameter of the embedded ring 202b is the same as the inner diameter of the gasket 204. When the fastening bolt 202a is locked, the bolt is pressed down to drive the embedded ring 202b into the gasket 204. The bolt continues to be pressed down, and the brim of the bolt top presses the gasket 204. The gasket 204, the embedded ring 202b and the annular groove 101c cooperate to form an accommodating space. The inner wall of the sealing filler 205 contacts the fastening bolt 202a. The sealing filler Material 205 is an acid- and alkali-resistant sealing material. The sealing filler 205 is placed in the accommodating space formed by the gasket 204, the embedded ring 202b and the annular groove 101c. The connection between the arc plate 101a and the fastening bolt 202a is sealed again to prevent the medium in the desulfurization tower from leaking from here. Preferably, the sealing filler 205 can be an acid- and alkali-resistant polymer material to prevent corrosion from the medium inside the desulfurization tower, extend the service life of the device, and further improve the anti-leakage effect. Preferably, the embedded ring 202b is embedded in the gasket 204 to extrude the sealing filler 205 in the annular groove 101c, and the sealing filler 205 is compressed to improve the sealing effect. Since the sealing filler 205 may have errors in the processing size, gaskets 204 of various sizes can be processed in advance to prevent the sealing filler 205 from being too short and the embedded ring 202b from being unable to compress the sealing filler 205.

[0034] Specifically, when tightening the fastening bolt, the downward pressure of the bolt will drive the embedded ring into the gasket. The bolt continues to be pressed downward, and the brim of the bolt top will press the gasket. The gasket, the embedded ring and the annular groove cooperate to form an accommodating space. The sealing filler is placed in the accommodating space formed by the gasket, the embedded ring and the annular groove. The connection between the arc plate and the fastening bolt is sealed again to prevent the medium in the desulfurization tower from leaking from here.
