Description

Technical Field

[0001] This utility model relates to the field of packing technology, specifically to a wall-flow-preventing structured packing. Background Technology

[0002] The wall flow effect of packing is a common fluid distribution problem in packed tower operation. Due to the gap between the tower wall and the packing, the fluid flow resistance is smaller. The fluid does not flow uniformly along the entire cross-section in the packing layer, but flows towards one side of the tower wall, which leads to a decrease in gas-liquid contact efficiency, reduces the effective mass transfer area, and affects the separation effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a structured packing material that prevents wall flow, in order to address the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A type of anti-wall flow structured packing is installed inside a packed tower. The anti-wall flow structured packing includes an outer ring, inside which a wire mesh packing is installed. The upper end of the outer ring extends upward, and a retaining ring is machined at the upper end of the outer ring. The outer ring of the retaining ring contacts the inner wall of the packed tower, and a guide plate is machined on the inner ring of the retaining ring, with the guide plate facing the wire mesh packing.

[0005] Furthermore, the baffle ring includes a lower baffle plate and an upper baffle plate, with an arc-shaped convex surface formed between the outer rings of the lower baffle plate and the upper baffle plate that contacts the inner wall of the packed tower. The inner ring of the upper baffle plate extends inward, and a guide plate is disposed on the extended end of the inner ring of the upper baffle plate.

[0006] Furthermore, the guide plate is filled with inclined wire mesh, and the angle between the guide plate and the upper baffle plate is 15°~20°.

[0007] Compared with the prior art, the anti-wall flow structured packing of this utility model reduces the gap between the packing and the tower wall by processing a baffle ring at the upper end of the packing and utilizing the contact between the baffle ring and the tower wall. At the same time, a guide plate is added to the baffle ring to make the liquid flow to one side of the packing, which not only ensures the separation effect, but also reduces the use of liquid distributors.

Detailed Implementation

[0009] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0010] like Figure 1 and Figure 2 As shown, a wall-flow-resistant structured packing is installed inside a packed tower. The wall-flow-resistant structured packing includes an outer ring 1, inside which a wire mesh packing 2 is installed. The upper end of the outer ring 1 extends upward, and a baffle ring 3 is machined at the upper end of the outer ring. The outer ring of the baffle ring 3 contacts the inner wall of the packed tower, reducing the gap between the baffle ring and the tower wall. A flow guide plate 4 is machined on the inner ring of the baffle ring 3, and the flow guide plate 4 faces the wire mesh packing 2. Since the baffle ring 3 reduces the gap between the baffle ring and the tower wall, the flow is guided to the middle position of the wire mesh packing 2 by the flow guide plate 4.

[0011] In this embodiment, the baffle ring 3 includes a lower baffle plate 311 and an upper baffle plate 312. The lower baffle plate 311 and the upper baffle plate 312 are processed by a flattening process, and an arc-shaped convex surface 313 that contacts the inner wall of the packed tower is formed between the outer rings of the lower baffle plate 311 and the upper baffle plate 312. The inner ring of the upper baffle plate 312 extends inward, and the guide plate 4 is disposed on the extended end of the inner ring of the upper baffle plate 312. The guide plate 4 is inclined towards the wire mesh packing, and the included angle between the guide plate 4 and the upper baffle plate 312 is 15°~20°.

[0012] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
