Description

Technical Field

[0002] An anti-wall flow ring is an auxiliary device for a packed tower, aiming to reduce or eliminate the wall flow phenomenon inside the tower, thereby improving the mass transfer efficiency of the tower. Wall flow refers to the flow of fluid along the tower wall, resulting in uneven fluid distribution inside the tower, which significantly reduces the separation efficiency of the tower. Anti-wall flow rings are usually used together with structured packings in a packed tower. They can be manufactured integrally with the packing or installed separately in the tower. Their design enables the fluid to flow more evenly over the tower wall, reducing the impact of wall flow and helping to improve the fluid dynamic performance inside the tower.

[0003] In the installation of existing anti-wall flow rings with packings, most of them are manufactured integrally with the anti-wall flow rings and the packings. When a large amount of fluid flows through, due to excessive pressure, the packing of the anti-wall flow ring may fall off, reducing the fluid dynamic performance inside the tower.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: a wall flow prevention ring, including a wall flow prevention ring main body 1, an outer shell 2 is fixedly connected to the outside of the wall flow prevention ring main body 1, a cover plate 3 is fixedly connected inside the outer shell 2, a slide bar 12 is fixedly connected inside the outer shell 2, a spring 4 is sleeved on the outer periphery of the slide bar 12, an insert block 5 is slidably connected to the outer periphery of the slide bar 12, a connecting rod 6 is rotatably connected to the outside of the insert block 5, and one end of the connecting rod 6 away from the insert block 5 is rotatably connected to a pusher block 7.

[0031] Specifically, the wall flow prevention ring main body 1 is the main body of the wall flow prevention ring. The outer shell 2 is used to support and install other components. The cover plate 3 prevents fluid from entering the inside of the outer shell 2 and affecting the normal operation of the components inside the outer shell 2. The slide bar 12 is used to support the stable sliding of the insert block 5 and prevent the spring 4 from shifting. The insert block 5 can be inserted into the packing to enable the stable installation of the packing and increase the ability of the packing to withstand the fluid pressure. The connecting rod 6 is used to transmit the thrust transmitted by the pusher block 7 to drive the movement of the insert block 5. The pusher block 7 is used to withstand the external thrust.

[0032] Referring to Figures 1 - 3 , the wall flow prevention ring main body 1 includes a wear-resistant layer 11. The wear-resistant layer 11 is fixedly connected to the outside of the outer shell 2. A carbon steel layer 8 is fixedly connected to the outside of the wear-resistant layer 11. An anticorrosion layer 9 is fixedly connected to the outside of the carbon steel layer 8. A resin layer 10 is fixedly connected to the outside of the anticorrosion layer 9.

[0033] Specifically, the outer side of the wear-resistant layer 11 is fixed to the outer side of the outer shell 2 to stably install the wear-resistant layer 11. The material of the wear-resistant layer 11 is ultra-high molecular weight polyethylene, which has extremely high wear resistance and extremely low friction coefficient, and can effectively protect the equipment and reduce wear. The outer side of the carbon steel layer 8 is fixed to the outer side of the wear-resistant layer 11 to stably install the carbon steel layer 8. The material of the carbon steel layer 8 is carbon steel, which can improve the uniform distribution of gas-liquid two-phase in the tower, thereby improving the mass transfer efficiency and the overall performance of the tower. The outer side of the anti-corrosion layer 9 is fixedly connected to the outer side of the carbon steel layer 8 to stably install the anti-corrosion layer 9. The material of the anti-corrosion layer 9 is butyl rubber, which has excellent heat resistance and chemical resistance and is suitable for anti-corrosion in high-temperature environments. The outer side of the resin layer 10 is fixedly connected to the outer side of the anti-corrosion layer 9 to stably install the resin layer 10. The material of the resin layer 10 is resin, which can absorb metal ions such as calcium and magnesium in the water flow.

[0034] Refer to Figures 1 - 3 , the outer side of the insertion block 5 is slidably connected inside the outer shell 2. The insertion block 5 penetrates the outer shell 2 and is inserted into the inside of the anti-wall-flow ring main body 1. The outer side of the push block 7 is slidably connected inside the outer shell 2. One end of the spring 4 is fixedly connected to the outer side of the outer shell 2. The other end of the spring 4 is fixedly connected to the outer side of the insertion block 5. The top of the push block 7 is fixedly connected with a button 13.

[0035] Specifically, the outer side of the insertion block 5 slides inside the outer shell 2, enabling the insertion block 5 to freely expand and contract. The insertion block 5 penetrates the outer shell 2 and is inserted into the inside of the anti-wall-flow ring main body 1, enabling the packing to be stably installed and increasing the ability of the packing to withstand fluid pressure. The outer side of the push block 7 slides inside the outer shell 2, enabling the push block 7 to freely slide. One end of the spring 4 is fixed to the outer side of the outer shell 2 and the other end is fixed to the outer side of the insertion block 5, enabling the spring 4 to compress the insertion block 5 to generate an elastic force, which can push the insertion block 5 to automatically reset. The outer side of the button 13 is fixedly connected to the top of the push block 7 for conveniently pressing the push block 7.

[0036] Working principle: When installing the packing, by pressing the button 13, the button 13 transmits the thrust to the push block 7 to drive the push block 7. The push block 7 transmits the thrust to the connecting rod 6 to drive the connecting rod 6. The connecting rod 6 rotates inside the push block 7 and the insertion block 5, driving the insertion block 5 to slide on the outer periphery of the slide rod 12. The insertion block 5 slides into the inside of the outer shell 2. When the insertion block 5 slides, it compresses the spring 4 to generate an elastic force. After placing the packing into the inside of the anti-wall-flow ring main body 1, release the button 13. The end of the insertion block 5 away from the spring 4 has a pointed design. The elastic force generated by the spring 4 pushes the insertion block 5, and the insertion block 5 extends out of the inside of the outer shell 2 and inserts into the inside of the packing, enabling the packing to be stably installed.
