Description

Technical Field

[0001] This utility model relates to the field of air drying canisters, specifically an air drying canister with anti-wall flow. Background Technology

[0002] Wall flow refers to the phenomenon in packed towers where, as liquid flows downwards along the packing layer, it gradually concentrates towards the tower wall, leading to an increase in liquid flow near the wall. This phenomenon causes uneven distribution of the gas and liquid phases within the packing layer, thereby reducing mass transfer efficiency. Wall flow can also cause gas blockage in the packed bed area, affecting the normal operation of the packed tower. To solve this problem, anti-wall flow rings are typically installed between the outer ring of the packing and the tower wall.

[0003] A wall-flow preventer is a technical measure used to prevent wall flow. It effectively reduces wall flow by installing a wall-flow preventer in the gap between the packing and the tower wall. The wall-flow preventer can be integrated with the packing or assembled separately inside the tower. Importantly, the wall-flow preventer should not completely seal the gap between the packing and the tower wall in the vertical direction; otherwise, it will reduce the tower throughput, increase resistance, and even cause a decrease in separation efficiency.

[0004] The structure of an air dryer is similar to that of a packed tower, so anti-wall flow rings can also be used in air dryers. However, the anti-wall flow rings used in the prior art are generally integral structures, which are only suitable for use with compatible packing materials. Moreover, their support and support effects are not strong enough, and they cannot support and support high-quality packing materials, affecting the convenience of installation and use. Furthermore, their elastic buffering effect is relatively poor. Therefore, this utility model proposes an anti-wall flow air dryer to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an air drying canister that prevents wall flow, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air drying canister with anti-wall flow capability, comprising:

[0007] A drying tank, the interior of which is filled with packing material, and an anti-wall flow ring is fitted on the outside of the packing material. A bracket is fixedly connected to the inner wall of the drying tank at the lower end of the anti-wall flow ring, and the bracket is fixed and limited by a fastener.

[0008] The anti-wall flow ring includes several sets of anti-wall flow blocks, which are connected in a ring shape by wire loops. The lower end of each anti-wall flow block is provided with a base support that is bent at a 90-degree angle. The packing is placed on the base support and fixed with bolts.

[0009] Preferably, the anti-wall flow block includes an upper support plate, and a lower support plate is integrally formed at the lower end of the upper support plate. The upper support plate and the lower support plate are set at a 50-degree angle. The ends are supported inward and attached to the outer wall of the packing. An arc-shaped spring piece is fixedly connected between the outer sides of the upper support plate and the lower support plate. A vertically set upright plate is integrally formed and fixedly connected at the lower end of the lower support plate. A bottom support is integrally formed at a 90-degree angle at the lower end of the upright plate. The bottom support is bent inward and has a through-hole on its end face.

[0010] Preferably, the anti-wall flow block has two sets of wire holes on its side, with wire rings threaded through the holes. Several sets of anti-wall flow blocks are connected by the wire rings to form an annular anti-wall flow ring.

[0011] Preferably, the fixing member includes a fixing plate at the lower end, the fixing plate has fixing holes, and fixing bolts pass through the fixing holes to connect to the inner wall of the drying tank to fix the fixing member as a whole. The fixing members are arranged in a ring array of several groups. A support plate is completely set at a 90-degree angle at the upper end of the fixing plate. The end of the support plate is angled upward at a 90-degree angle to form a clamping plate. A limiting groove is formed between the clamping plate and the inner wall of the drying tank.

[0012] Preferably, the bracket is circular and includes an outer ring for holding the bracket. The ring is provided with grid bars evenly distributed in a ring-shaped pattern inside. The ring is inserted into a limiting slot formed at the upper end of the fixing member. The grid opening formed between the grid bars is fitted outside the clamping plate. The grid bars restrict the rotation of the bracket. The filler and anti-wall flow ring are placed at the upper end of the bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting up an assembled anti-wall flow ring, increases the convenience of installation and disassembly while ensuring anti-wall flow. The anti-wall flow blocks are connected by wire rings, and several can be connected to form a ring as needed to adapt to different specifications of drying tanks and packings. An arc-shaped spring is also provided on the outside of the anti-wall flow block to provide a buffering effect when the anti-wall flow block is squeezed by the packing, further improving adaptability, increasing the fault tolerance, and ensuring both clamping tightness and anti-wall flow effect. A bracket is also provided at the lower end of the packing and anti-wall flow ring to further ensure the stability of the packing and anti-wall flow ring and improve the use effect.

A vertically set upright plate 12 is integrally formed and fixedly connected at the lower end of the lower support plate 11. A bottom support 7 is integrally formed at a 90-degree angle at the lower end of the upright plate 12. The bottom support 7 is bent inward and has a through-hole on the end face. The arc-shaped spring piece 9 on the outer side of the anti-wall flow block can provide a buffering effect when the anti-wall flow block 6 is squeezed by the packing 2, further improving adaptability, increasing fault tolerance, and ensuring the clamping degree while ensuring the anti-wall flow effect.

[0027] The anti-wall flow block 6 has two sets of wire holes 13 through the side, and wire rings 8 are threaded through the wire holes 13.
