Description

Technical Field

[0001] The invention relates to the technical field of engineering equipment, and in particular to an orifice plate mounting structure of an adsorption tower section, an adsorption tower section and an adsorption tower. Background Art

[0002] Activated carbon flue gas desulfurization and denitrification purification equipment is widely used in metallurgy, building materials, electricity and other industries. The equipment uses the adsorption characteristics of activated carbon media to purify flue gas. The activated carbon flue gas purification system generally uses a tower reaction container (adsorption tower), loads the activated carbon medium into the container, and uses the medium's own weight to form a material flow. The flue gas enters from one side of the reactor, passes through the activated carbon flow layer, and then outputs from the other side of the reactor. The sulfur-rich and nitrate-rich gases in the flue gas are adsorbed by the activated carbon and separated from the flue gas, achieving the purpose of flue gas purification. In the adsorption tower medium container, orifice plates with a certain aperture are regularly set to separate the activated carbon medium in different material flow channels to form a regular activated carbon material flow layer. The adsorption tower section is the main component structure of the adsorption tower. Each adsorption tower equipment contains dozens of adsorption tower sections, and each set of adsorption tower sections is equipped with dozens of orifice plates.

[0003] Currently, if Figure 1 and Figure 2 As shown in the figure, the orifice plate is generally fixed in the adsorption tower section by bolts and pressure plates. In one set of adsorption tower equipment, the number of bolts used to fasten the orifice plate alone is as high as nearly 100,000 sets. This connection method requires drilling a large number of bolt holes and a large number of bolts, which has high production costs and consumes a lot of bolt resources; a large number of bolt connections require high installation and disassembly work intensity, and the equipment production, installation, and maintenance cycle are long; the equipment working environment is harsh, the bolt pair is prone to rust, maintenance and replacement are difficult, and the bolt pair resources are wasted. Summary of the invention

[0004] The present invention proposes an orifice plate installation structure for an adsorption tower section, which is used to solve the defects of the orifice plate connection method in the prior art, such as high manufacturing cost, high intensity of assembly and disassembly work, high difficulty in maintenance and replacement, and large waste of bolt pair resources. An open slot-type structure matched with a mounting frame is provided on the orifice plate, so that the orifice plate and the mounting plate can be quickly installed and disassembled, and the drilling cost and bolt procurement cost required for the bolt connection structure are saved. Compared with the bolt connection structure, the dimensional accuracy requirements for the workpiece are low and the manufacturing difficulty is low, which improves the safety of maintenance operations and avoids the problem that sparks may be generated when the bolt pair is rusted and destructively dismantled, thereby posing a safety hazard risk to equipment and maintenance personnel.

[0005] The present invention also proposes an adsorption tower section to solve the defects of the connection method of the orifice plate in the prior art, such as high manufacturing cost, high intensity of assembly and disassembly work, high difficulty in maintenance and replacement, and large waste of bolt pair resources. By arranging an open groove-type structure that cooperates with the mounting frame on the orifice plate in the adsorption tower section, the orifice plate and the mounting plate can be quickly installed and disassembled, saving the drilling cost and bolt procurement cost required for the bolt connection structure. Compared with the bolt connection structure, the dimensional accuracy requirements for the workpiece are low and the manufacturing difficulty is low, which improves the safety of maintenance operations and avoids the problem of sparks that may be generated during the destructive removal of rusted bolt pairs, posing a safety hazard risk to equipment and maintenance personnel.

[0006] The present invention further proposes an adsorption tower to solve the defects of the prior art in that the connection method of the orifice plate has high manufacturing cost, high intensity of assembly and disassembly work, high difficulty in maintenance and replacement, and large waste of bolt pair resources. By arranging an open groove-type structure that cooperates with the mounting frame on the orifice plate in the adsorption tower section, the orifice plate and the mounting plate can be quickly installed and disassembled, saving the drilling cost and bolt procurement cost required for the bolt connection structure. Compared with the bolt connection structure, the dimensional accuracy requirements for the workpiece are low and the manufacturing difficulty is low, which improves the safety of maintenance operations and avoids the problem of sparks that may be generated during the destructive removal of rusted bolt pairs, posing a safety hazard risk to equipment and maintenance personnel.

[0008] The installation frame is provided with a plurality of installation openings;

[0009] The orifice plate is detachably connected to the installation frame corresponding to the installation opening;

[0010] Wherein, a lap joint is provided on the peripheral wall of at least one side of the orifice plate, and the lap joint is overlapped and matched with the installation frame at the installation opening to realize the positioning of the orifice plate and the installation frame.

[0011] According to an embodiment of the present invention, the overlapping portion includes a top overlapping unit and a bottom overlapping unit which are arranged along the vertical direction close to one side of the orifice plate opposite to two side walls.

[0012] Specifically, this embodiment provides an implementation method of the overlap portion, by providing a top overlap unit and a bottom overlap unit in the vertical direction of the orifice plate, so that the orifice plate can be overlapped with the installation frame at the installation opening through the top overlap unit and the bottom overlap unit.

[0013] It should be noted that the specific setting positions of the top lap unit and the bottom lap unit can be aligned with the corresponding side walls of the orifice plate, or a certain distance can be left. The distance means that the top lap unit and / or the bottom lap unit have a certain distance from the side wall of the orifice plate. Both of the above methods can be implemented here. The present invention does not make too many restrictions. In practical applications, it can be selected according to actual conditions.

[0014] According to one embodiment of the present invention, the top overlapping unit and the bottom overlapping unit are open grooves provided on the same side plate surface of the orifice plate;

By providing the specific structure of the top overlapping unit and the bottom overlapping unit, the orifice plate can be overlapped with the installation frame at the installation port under the action of the top overlapping unit and the bottom overlapping unit, thereby realizing the positioning of the orifice plate at the installation port.

[0018] It should be noted that by setting the top overlapping unit and the bottom overlapping unit as an open groove structure, the top overlapping unit and the bottom overlapping unit are overlapped with the installation frame through the open groove. At the same time, the open groove can also realize the limitation of the top overlapping unit and the bottom overlapping unit, thereby realizing the limitation of the orifice plate, ensuring the stability of the overlap of the orifice plate at the installation frame, and also achieving the effect of easy installation and disassembly.

[0019] According to one embodiment of the present invention, the groove depth of the top overlapping unit is greater than the groove depth of the bottom overlapping unit;

The orifice plate is then placed upright, and the bottom overlapping unit automatically passes through the installation opening. The orifice plate is then moved vertically downward to achieve overlapping of the top overlapping unit and the bottom overlapping unit with the installation frame.

[0023] Furthermore, when disassembling, the orifice plate is lifted in the vertical direction, the bottom overlapping unit is pushed and pulled outward to be released from the installation opening, and then the inclined orifice plate is removed from the installation opening as a whole, and the top overlapping unit is automatically released.

[0024] It should be noted that the maximum distance between the top overlapping unit and the bottom overlapping unit refers to the distance between the farthest ends of the top overlapping unit and the bottom overlapping unit in the vertical direction.

[0025] According to an embodiment of the present invention, the overlapping portion comprises a first side overlapping unit and a second side overlapping unit which are arranged on two opposite side walls of the orifice plate along a horizontal direction.

[0027] It should be noted that the specific setting positions of the first side lap joint unit and the second side lap joint unit can be aligned with the corresponding side walls of the orifice plate, or a certain distance can be left. The distance means that the first side lap joint unit and / or the second side lap joint unit have a certain distance from the side wall of the orifice plate. Both of the above methods can be implemented here. The present invention does not make too many restrictions. In practical applications, it can be selected according to actual conditions.

[0028] According to an embodiment of the present invention, the first side overlap unit and the second side overlap unit are open grooves provided on the same side plate surface of the orifice plate;

[0029] Wherein, the opening directions of the first side overlapping unit and the second side overlapping unit are arranged in opposite directions;

[0030] The plate surface area of ​​the orifice plate is larger than the area of ​​the mounting opening.

By providing the specific structure of the first side overlap unit and the second side overlap unit, the orifice plate can be overlapped with the installation frame at the installation port under the action of the first side overlap unit and the second side overlap unit, thereby realizing the positioning of the orifice plate at the installation port.

[0032] It should be noted that, by setting the first side overlapping unit and the second side overlapping unit as an open groove structure, the first side overlapping unit and the second side overlapping unit are overlapped with the installation frame through the open groove, and the open groove can also realize the limitation of the first side overlapping unit and the second side overlapping unit, thereby realizing the limitation of the orifice plate, ensuring the stability of the overlap of the orifice plate at the installation frame, and also realizing the effect of easy installation and disassembly.

[0033] According to an embodiment of the present invention, the groove depth of the first lap joint unit of the side portion is greater than the groove depth of the second lap joint unit of the side portion;

[0035] The difference between the maximum distance between the first side overlapping unit and the second side overlapping unit and the groove depth of the first side overlapping unit is less than or equal to the size of the installation opening along the horizontal direction.

[0036] Specifically, this embodiment provides another type of first side overlapping unit and second side overlapping unit. By providing a size ratio between the first side overlapping unit and the second side overlapping unit, during installation, the orifice plate is tilted and placed, and the first side overlapping unit is passed through the installation opening to overlap with the installation frame. The orifice plate and the installation frame are then placed parallel to each other. At this time, the second side overlapping unit automatically passes through the installation opening, and the orifice plate is moved to the side of the second side overlapping unit to achieve overlap between the first side overlapping unit and the second side overlapping unit and the installation frame.

[0037] Furthermore, when disassembling, the orifice plate is moved toward the first side overlap unit, and after the second side overlap unit is pushed and pulled outward to disengage from the installation opening, the inclined orifice plate is removed from the installation opening as a whole, and the first side overlap unit is automatically disengaged.

[0038] It should be noted that the maximum distance between the first side overlapping unit and the second side overlapping unit refers to the distance between the farthest ends of the first side overlapping unit and the second side overlapping unit in the horizontal direction.

At this time, the side first overlap unit automatically passes through the installation opening, and then the orifice plate is moved to the side of the side first overlap unit to achieve the overlap between the side first overlap unit and the side second overlap unit and the installation frame.

[0043] Furthermore, when disassembling, the orifice plate is moved toward the side of the second side overlap unit, and after the first side overlap unit is pushed and pulled outward to disengage from the installation opening, the inclined orifice plate is removed from the installation opening as a whole, and the second side overlap unit is automatically disengaged.

[0072] In detail, the present invention proposes an installation structure of an orifice plate 20 of an adsorption tower section, which is used to solve the defects of the connection method of the orifice plate 20 in the prior art, such as high manufacturing cost, high intensity of assembly and disassembly work, high difficulty in maintenance and replacement, and large waste of bolt pair resources. By providing an open groove-type structure that cooperates with the mounting frame 10 on the orifice plate 20, rapid installation and disassembly of the orifice plate 20 and the mounting plate can be achieved, saving the drilling cost and bolt procurement cost required for the bolt connection structure. Compared with the bolt connection structure, the dimensional accuracy requirements for the workpiece are low and the manufacturing difficulty is low, which improves the safety of maintenance operations and avoids the problem that sparks may be generated during the destructive removal of rusted bolt pairs, posing a safety hazard risk to equipment and maintenance personnel.

[0073] In some possible embodiments of the present invention, the overlapping portion includes a top overlapping unit 30 and a bottom overlapping unit 40 which are arranged along the vertical direction at one side of the orifice plate 20 opposite to the two side walls.

[0074] Specifically, this embodiment provides an implementation method of the overlapping portion, by arranging a top overlapping unit 30 and a bottom overlapping unit 40 in the vertical direction of the orifice plate 20, so that the orifice plate 20 can be overlapped with the installation frame 10 at the installation opening 11 through the top overlapping unit 30 and the bottom overlapping unit 40.

[0075] It should be noted that the specific setting positions of the top lap unit 30 and the bottom lap unit 40 can be aligned with the corresponding side walls of the orifice plate 20, or a certain distance can be left. The distance means that the top lap unit 30 and / or the bottom lap unit 40 have a certain distance from the side wall of the orifice plate 20. Both of the above methods can be implemented here. The present invention does not make too many restrictions. In practical applications, it can be selected according to actual conditions.

[0076] In some possible embodiments of the present invention, the top overlap unit 30 and the bottom overlap unit 40 are open grooves arranged on the same side plate surface of the orifice plate 20; wherein, the opening directions of the top overlap unit 30 and the bottom overlap unit 40 are arranged in back-to-back directions; and the plate surface area of ​​the orifice plate 20 is larger than the area of ​​the mounting opening 11.

[0077] Specifically, this embodiment provides an implementation method of a top overlapping unit 30 and a bottom overlapping unit 40. By providing the specific structure of the top overlapping unit 30 and the bottom overlapping unit 40, the orifice plate 20 can be overlapped with the installation frame 10 at the installation opening 11 under the action of the top overlapping unit 30 and the bottom overlapping unit 40, thereby realizing the positioning of the orifice plate 20 at the installation opening 11.

[0078] It should be noted that by setting the top overlapping unit 30 and the bottom overlapping unit 40 as an open groove structure, the top overlapping unit 30 and the bottom overlapping unit 40 are overlapped with the installation frame 10 through the open groove. At the same time, the open groove can also limit the top overlapping unit 30 and the bottom overlapping unit 40, and then limit the orifice plate 20, thereby ensuring the stability of the overlap of the orifice plate 20 at the installation frame 10, and also achieving the effect of easy installation and disassembly.

[0079] In some possible embodiments of the present invention, the groove depth of the top overlap unit 30 is greater than the groove depth of the bottom overlap unit 40; wherein, the difference between the maximum distance between the top overlap unit 30 and the bottom overlap unit 40 and the groove depth of the bottom overlap unit 40 is greater than the dimension of the mounting opening 11 along the vertical direction; the difference between the maximum distance between the top overlap unit 30 and the bottom overlap unit 40 and the groove depth of the top overlap unit 30 is less than or equal to the dimension of the mounting opening 11 along the vertical direction.

[0080] Specifically, this embodiment provides another implementation method of the top overlap unit 30 and the bottom overlap unit 40. By providing a size ratio between the top overlap unit 30 and the bottom overlap unit 40, during installation, the orifice plate 20 is tilted and placed, and the top overlap unit 30 is overlapped with the installation frame 10 through the installation opening 11. The orifice plate 20 is then placed upright. At this time, the bottom overlap unit 40 automatically passes through the installation opening 11. The orifice plate 20 is then moved vertically downward to achieve overlap between the top overlap unit 30 and the bottom overlap unit 40 and the installation frame 10.

[0081] Furthermore, when disassembling, the orifice plate 20 is lifted in the vertical direction, and the bottom overlapping unit 40 is pushed and pulled outward to be released from the installation opening 11, and then the inclined orifice plate 20 is removed from the installation opening 11 as a whole, and the top overlapping unit 30 is automatically released.

[0082] It should be noted that the maximum distance between the top overlapping unit 30 and the bottom overlapping unit 40 refers to the distance between the farthest ends of the top overlapping unit 30 and the bottom overlapping unit 40 in the vertical direction.

[0083] In some possible embodiments of the present invention, the overlapping portion includes a first side overlapping unit 50 and a second side overlapping unit 60 which are arranged on two opposite side walls of the orifice plate 20 along the horizontal direction.

[0084] Specifically, this embodiment provides another implementation method of the overlapping portion, by setting a first side overlapping unit 50 and a second side overlapping unit 60 in the horizontal direction of the orifice plate 20, so that the orifice plate 20 can be overlapped with the installation frame 10 at the installation opening 11 through the first side overlapping unit 50 and the second side overlapping unit 60.

[0085] It should be noted that the specific setting positions of the first side lap joint unit 50 and the second side lap joint unit 60 can be aligned with the corresponding side walls of the orifice plate 20, or a certain spacing can be left. The spacing refers to the first side lap joint unit 50 and / or the second side lap joint unit 60 having a certain distance from the side wall of the orifice plate 20. Both of the above methods can be implemented here. The present invention does not make too many restrictions. In practical applications, it can be selected according to actual conditions.

[0086] In some possible embodiments of the present invention, the first side lap unit 50 and the second side lap unit 60 are open grooves arranged on the same side plate surface of the orifice plate 20; wherein, the opening directions of the first side lap unit 50 and the second side lap unit 60 are arranged in back-to-back directions; and the plate surface area of ​​the orifice plate 20 is larger than the area of ​​the mounting opening 11.

[0087] Specifically, this embodiment provides an implementation method of a first side overlap unit 50 and a second side overlap unit 60. By providing the specific structure of the first side overlap unit 50 and the second side overlap unit 60, the orifice plate 20 can be overlapped with the installation frame 10 at the installation opening 11 under the action of the first side overlap unit 50 and the second side overlap unit 60, thereby realizing the positioning of the orifice plate 20 at the installation opening 11.

[0088] It should be noted that, by setting the first side overlapping unit 50 and the second side overlapping unit 60 as an open groove structure, the first side overlapping unit 50 and the second side overlapping unit 60 are overlapped with the installation frame 10 through the open groove, and the open groove can also realize the limitation of the first side overlapping unit 50 and the second side overlapping unit 60, and then realize the limitation of the orifice plate 20, which ensures the stability of the overlap of the orifice plate 20 at the installation frame 10, and also realizes the effect of easy installation and disassembly.

[0089] In some possible embodiments of the present invention, the groove depth of the first side overlap unit 50 is greater than the groove depth of the second side overlap unit 60; wherein, the difference between the maximum distance between the first side overlap unit 50 and the second side overlap unit 60 and the groove depth of the second side overlap unit 60 is greater than the size of the installation opening 11 along the horizontal direction; the difference between the maximum distance between the first side overlap unit 50 and the second side overlap unit 60 and the groove depth of the first side overlap unit 50 is less than or equal to the size of the installation opening 11 along the horizontal direction.

[0090] Specifically, the present embodiment provides another type of first side overlap unit 50 and second side overlap unit 60. By providing a size ratio between the first side overlap unit 50 and the second side overlap unit 60, during installation, the orifice plate 20 is tilted and placed, and the first side overlap unit 50 is overlapped with the installation frame 10 through the installation opening 11. The orifice plate 20 is then placed parallel to the installation frame 10. At this time, the second side overlap unit 60 automatically passes through the installation opening 11, and the orifice plate 20 is moved to the side of the second side overlap unit 60 to achieve the overlap between the first side overlap unit 50 and the second side overlap unit 60 and the installation frame 10.

[0091] Furthermore, when disassembling, the orifice plate 20 is moved toward the side of the first side lap unit 50, and the second side lap unit 60 is pushed and pulled outward to be released from the installation opening 11, and then the inclined orifice plate 20 is removed from the installation opening 11 as a whole, and the first side lap unit 50 is automatically released.

[0092] It should be noted that the maximum distance between the first side overlapping unit 50 and the second side overlapping unit 60 refers to the distance between the farthest ends of the first side overlapping unit 50 and the second side overlapping unit 60 in the horizontal direction.

[0093] In some possible embodiments of the present invention, the groove depth of the first side overlap unit 50 is smaller than the groove depth of the second side overlap unit 60; wherein, the difference between the maximum distance between the first side overlap unit 50 and the second side overlap unit 60 and the groove depth of the first side overlap unit 50 is greater than the size of the installation opening 11 along the horizontal direction; the difference between the maximum distance between the first side overlap unit 50 and the second side overlap unit 60 and the groove depth of the second side overlap unit 60 is less than or equal to the size of the installation opening 11 along the horizontal direction.

[0094] Specifically, the present embodiment provides another kind of side first overlap unit 50 and side second overlap unit 60, by providing the size ratio between the side first overlap unit 50 and the side second overlap unit 60, so that during installation, the orifice plate 20 is tilted and placed, and the side second overlap unit 60 is overlapped with the installation frame 10 through the installation opening 11, and then the orifice plate 20 is placed parallel to the installation frame 10. At this time, the side first overlap unit 50 automatically passes through the installation opening 11, and then the orifice plate 20 is moved to the side of the side first overlap unit 50, so as to realize the overlap between the side first overlap unit 50 and the side second overlap unit 60 and the installation frame 10.

[0095] Furthermore, when disassembling, the orifice plate 20 is moved toward the side of the second side lap unit 60, and after the first side lap unit 50 is pushed and pulled outward to disengage from the installation opening 11, the inclined orifice plate 20 is removed from the installation opening 11 as a whole, and the second side lap unit 60 is automatically disengaged.

[0096] It should be noted that the maximum distance between the first side overlapping unit 50 and the second side overlapping unit 60 refers to the distance between the farthest ends of the first side overlapping unit 50 and the second side overlapping unit 60 in the horizontal direction.
