Description

Technical Field

[0001] The utility model belongs to the technical field of packed towers, and more specifically relates to a grid positioning device for a packed tower and a packed tower. Background Art

[0002] A catalyst is arranged in the packed tower, and a packing pressure plate is arranged above the catalyst. The packing pressure plate is pressed on the top of the catalyst to prevent the catalyst from being driven to move upward when the reaction medium flows upward from the bottom of the packed tower, thereby destroying the designed stacking structure of the catalyst and affecting the catalytic effect of the catalyst.

[0003] In the prior art, the packing plate includes a wire mesh and a grid plate, and the wire mesh cover is arranged above the catalyst and fixed by the grid plate. When the inner diameter of the packing tower is large, for example, when the inner diameter of the packing tower exceeds 3m, the required grid plate diameter is also large. In addition, the grid plate needs to be installed in the packing tower after the catalyst is loaded, resulting in the grid plates needing to be put into the packing tower one by one and then assembled in the packing tower.

[0004] At present, the following method is generally used to prevent the grid plates from moving upward in the packed tower: support rods are installed on the inner wall of the packed tower, and the grid plates are installed on the top of the support rods by wires or bolts. The above installation method has the following problems: multiple grid plates need to be connected to the support rods one by one by construction workers through wires or bolts, which increases the difficulty of installing the grid plates and is time-consuming and labor-intensive; in addition, when the wires or bolts are connected to the grid plates, the grid plates will be displaced under the traction of the wires or bolts to produce installation errors, affecting the installation accuracy of the grid plates; and the wires or bolts are prone to breakage and other failures after long-term use, which leads to the failure of the grid plates. After the grid plates fail, they cannot effectively limit the catalyst, and the catalyst may be carried upward by the reaction medium, shortening the operation cycle of the packed tower.

The edges of the at least two groups of grid plates 1 close to the inner wall 18 of the packed tower are arranged to form an arc shape that matches the inner wall 18 of the packed tower. Each group of grid plates 1 forms a butt joint 2 near its arc position. The edges of the two adjacent groups of grid plates 1 that are in contact with each other are arranged to be flush. Each group of grid plates 1 forms a butt joint 3 near its flush position. Each group of grid plates 1 includes several grid plates 1, which can be arranged as needed; such as Figure 3 As shown, in this embodiment, three groups of grid plates 1 are arranged in the packed tower, and each group of grid plates 1 includes six grid plates 1 .

The grid plate 1 is crimped and positioned using the top pressure beam 5. One top pressure beam 5 can press the upper side of the docking portion 3 of two adjacent groups of grid plates 1 inside the packing tower. The length of the top pressure beam 5 is smaller than the inner circumferential diameter of the side pressure beam 4, so that when the top pressure beam 5 is installed on the first connecting structure 6, the top pressure beam 5 is inside the side pressure beam 4, and is pressed on the upper side of the grid plate 1 by the side pressure beam 4 and the top pressure beam 5.

[0040] Optionally, the top pressure beam 5 includes a pressure plate 7 and a connecting plate 8 arranged on a side of the pressure plate 7 away from the grid plate 1 , and the connecting plate 8 is connected to the pressure plate 7 to form an inverted T-shaped structure.

The clamping bolts 11 on the plane ends of the first L-shaped plate 9 and the second L-shaped plate 10 can be used to extend the pressure plate 7 downward to clamp the top pressure beam 5, thereby ensuring the stability of the pressure plate 7 crimped to the grid plate 1.

[0044] Optionally, the length of the second L-shaped plate 10 is smaller than that of the first L-shaped plate 9 , and an escape zone 13 is formed at one end of the second L-shaped plate 10 close to the interior of the packed tower, and the escape zone 13 is used to escape the connecting plate 8 .

The first connecting hole 14 is a long waist hole extending along the length direction of the top pressure beam 5, and the second connecting hole 15 is a long waist hole extending vertically.

[0047] Specifically, the first connecting hole 14 is a long waist hole extending in the horizontal direction, so as to allow the top pressure beam 5 and the first connecting structure 6 to move relative to each other when the packing tower expands or contracts, thereby avoiding stress at the connection between the two; the second connecting hole 15 is a long waist hole extending in the vertical direction, so that the top pressure beam 5 can be displaced in the vertical direction relative to the first connecting structure 6, so as to be tightened on the pressure plate 7 of the top pressure beam 5 by the tightening bolts 11 on the planar ends of the first L-shaped plate 9 and the second L-shaped plate 10, and the pressure plate 7 is effectively crimped on the grid plate 1.

[0048] Optionally, the top pressure beam 5 further includes a reinforcing plate 16 , and the reinforcing plate 16 is arranged on a side of the pressure plate 7 away from the grid plate 1 .

[0049] Specifically, the cross section of the position where the reinforcing plate 16 is connected to the pressure plate 7 forms an inverted T shape, and the reinforcing plate 16 increases the strength of the top pressure beam 5, thereby improving its service life and the positioning effect on the grid plate 1.

[0050] In this embodiment, if Figure 6 As shown, the reinforcing plate 16 and the connecting plate 8 are an integrated structure.

[0051] Optionally, a supporting beam 17 is further included. The supporting beam 17 is arranged at the lower side of the docking portion 3 , and both ends of the supporting beam 17 are detachably connected to the inner wall 18 of the packing tower through a second connecting structure 19 .

For example, each second connecting structure 19 can include two welding plates, and the two welding plates are welded to the inner side of the inner wall 18 of the packing tower at intervals. The supporting beam 17 can be connected to the welding plate by screwing or riveting.
