Description

Technical Field

[0001] This utility model relates to the field of corrugated packing technology, and in particular to a corrosion-resistant corrugated packing for towers. Background Technology

[0002] Corrugated packing is a widely used device in the chemical and environmental protection fields, primarily used to increase the gas-liquid contact area and promote gas-liquid mixing and mass transfer processes. Corrugated packing is typically made of materials such as metal wire mesh or ceramics, and has a regular corrugated structure that significantly improves gas-liquid contact efficiency and separation effect. Corrugated packing is also a new type of water purification material, widely used in water treatment, chemical production, and other fields.

[0003] In existing technologies, the installation method of corrugated packing inside the tower typically requires it to completely cover the same area of ​​the tower cross-section. This design causes the gas-liquid two-phase flow to continuously impact the bottom structure of the fixed area when passing through the packing layer. Under long-term operation, local stress concentration can easily lead to fatigue damage to the bottom material. Once damage occurs at a specific location, it is often necessary to replace the entire packing module, resulting in a significant increase in maintenance costs.

[0004] Therefore, improvements are proposed. Utility Model Content

[0005] This invention is a corrosion-resistant corrugated packing for towers, proposed to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion-resistant corrugated packing for towers, comprising a packing body, a clamp fixedly sleeved on the outer surface of the packing body, a sealing ring fixedly connected to the bottom of the clamp, an annular support seat sleeved on the bottom of the outer surface of the sealing ring, and a lower packing fixedly installed inside the annular support seat;

[0007] Multiple positioning sleeves are uniformly fixedly connected to the outer surface of the clamp. Each of the multiple positioning sleeves is equipped with a pull rope elastic pin. The multiple pull rope elastic pins are jointly fixedly connected to a drive ring, and the drive ring is threaded onto the top of the outer surface of the clamp.

[0008] Each of the aforementioned positioning sleeves has a positioning pin inserted into it for limiting positioning. The positioning pin is fixedly connected to the annular support base and is matched with an elastic pin with a pull rope.

[0009] Furthermore, the annular support includes a mounting ring, the inner surface of which is fixedly connected to a lower hoop, and the lower filler is fixedly installed on the inner side of the lower hoop. The top of the lower hoop is provided with an annular groove, which matches the sealing ring. The annular groove and the sealing ring are designed to seal and connect with the lower hoop using a clamp.

[0010] Furthermore, each of the multiple positioning sleeves includes a housing, and the housing is fixedly installed on the outer surface of the clamp. The top of the housing is provided with a positioning hole, and the positioning sleeve cooperates with the positioning post to be positioned and installed using the clamp.

[0011] Furthermore, each of the multiple elastic pins with pull cords includes a mounting groove, which is formed on the inner wall of one side of the positioning hole. A spring is fixedly connected to the inner wall of one side of the mounting groove, and a limit pin is fixedly connected to the other end of the spring. The limit pin slides against the inner wall of the mounting groove. A pull cord body is fixedly connected to one end of the limit pin located on the spring. The pull cord body extends through the inner wall of the mounting groove to the top of the housing and is fixedly connected to the drive ring. When there is no external force, the limit pin is always in the extended state under the action of the spring.

[0012] Furthermore, each of the multiple positioning columns includes a column body, and the column body is fixedly installed on the top of the mounting ring and matches the positioning hole. A limiting groove is opened on one side of the outer surface of the column body, and the limiting groove matches the limiting pin. The mounting ring facilitates the overall installation inside the packed tower.

[0013] Furthermore, both the packing body and the lower packing are made of stainless steel, which has good corrosion resistance and strength and is suitable for various industrial environments.

[0014] Furthermore, the drive ring has multiple protrusions to increase the friction on the outer surface of the drive ring, which facilitates manual rotation of the drive ring.

[0015] The beneficial effects of this utility model are:

[0016] In use, this utility model provides a corrosion-resistant corrugated packing for towers. Through the cooperation structure of the clamp and the annular support seat, the main body of the packing and the lower packing are modularly separated. When the bottom of the packing is damaged, only the corresponding parts need to be replaced. The linkage mechanism with the elastic pin with the pull rope controlled by the drive ring enables quick disassembly and assembly. The limiting structure of the positioning column and the positioning sleeve ensures the stability of the installation, effectively solving the problem of high maintenance costs caused by the overall replacement of traditional corrugated packing.

An annular groove is provided on the top of the lower clamp 6, and the annular groove matches the sealing ring 3. The surfaces of the annular support seat, clamp 4, and sealing ring 3 are all treated with anti-corrosion coating to ensure their corrosion resistance. Existing corrosion-resistant sealing rings are fixedly connected to both the inner and outer surfaces of the sealing ring 3 to ensure the sealing between the sealing ring 3 and the annular groove.

[0025] Multiple positioning sleeves are uniformly fixedly connected to the outer surface of the clamp 4. Each positioning sleeve has an elastic pin with a pull cord installed inside. These multiple elastic pins are jointly fixedly connected to a drive ring 5, which is threaded onto the top of the outer surface of the clamp 4. The drive ring 5 has multiple protrusions. Each positioning sleeve includes a housing 2, which is fixedly installed on the outer surface of the clamp 4. A positioning hole 12 is provided at the top of the housing 2. Both the outer and inner surfaces of the positioning sleeves are treated with anti-corrosion coatings to ensure their corrosion resistance. Each elastic pin with a pull cord includes a mounting groove 14, which is located within the positioning hole 1. On one side of the inner wall of the housing 2, a spring 15 is fixedly connected to the inner wall of the mounting groove 14. The other end of the spring 15 is fixedly connected to a limit pin 13, and the limit pin 13 slides against the inner wall of the mounting groove 14. The limit pin 13 is fixedly connected to a pull rope body 16 at one end of the spring 15, and the pull rope body 16 extends through the inner wall of the mounting groove 14 to the top of the housing 2 and is fixedly connected to the drive ring 5. The spring 15 is made of stainless steel, and the limit pin 13 and the pull rope body 16 are made of polyester.
