Description

Technical Field

[0001] This utility model relates to the field of packing technology, specifically to a packing material with a sealing device to prevent wall flow. Background Technology

[0002] When liquid flows downward along the packing layer in a packed tower, it tends to gradually concentrate towards the tower wall, causing the liquid flow rate near the tower wall to gradually increase. This phenomenon is called wall flow. The wall flow effect leads to a decrease in mass transfer efficiency, resulting in energy waste and increased costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wall-flow prevention packing with a sealing device, which addresses 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 wall-flow prevention packing with a sealing device includes an outer ring, a packing body disposed inside the outer ring, an installation ring disposed on the outer bottom of the outer ring, a fixed ring and a movable ring disposed on the outer upper side of the outer ring, a sealing ring installed between the fixed ring and the movable ring, push rod seats evenly distributed around the periphery of the outer ring, a push rod disposed inside the push rod seat, one end of the push rod facing the movable ring, and an adjusting screw disposed on the installation ring corresponding to the position of the push rod, the adjusting screw facing the other end of the push rod.

[0005] Furthermore, the movable ring is provided with multiple guide pins, which pass through the movable ring and connect to the fixed ring.

[0006] Furthermore, the sealing ring has a hollow internal structure.

[0007] Furthermore, the mounting ring is provided with a screw seat, and the adjusting screw is connected to the screw seat.

[0008] Furthermore, an annular overflow groove is provided on the inner side above the outer ring, and a liquid guiding groove is connected inside the annular overflow groove. An overflow port is provided on the overflow groove and communicates with the liquid guiding groove. A liquid collecting groove is connected in the middle of the liquid guiding groove. The liquid collecting groove is located in the middle of the packing body, and a drain pipe is provided in the middle of the liquid collecting groove.

[0009] Compared with the prior art, the anti-wall flow packing with a sealing device of this utility model improves the sealing performance between the packing periphery and the tower wall by squeezing the sealing ring during packing installation, reduces gaps, and reduces wall flow phenomenon. At the same time, the liquid is introduced into the packing body from the middle through the overflow groove, liquid guiding groove and liquid collecting groove for continued separation, thereby improving mass transfer efficiency.

[0011] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0012] like Figure 1 and Figure 2 As shown, a wall-flow prevention packing with a sealing device includes an outer ring 1, a packing body 2 inside the outer ring 1, and an installation ring 3 on the outer bottom outer side of the outer ring 1 for installation inside the tower body. A fixed ring 4 and a movable ring 5 are provided on the upper outer side of the outer ring 1. Multiple guide pins 6 are provided on the movable ring 5, and the guide pins 6 pass through the movable ring 5 and connect to the fixed ring 4, so that the movable ring 5 moves below the fixed ring 4. A sealing ring 7 is installed between the fixed ring 4 and the movable ring 5. Four to eight push rod seats 8 are evenly distributed around the periphery of the outer ring 1. A push rod 9 is provided inside the push rod seat 8, with one end of the push rod 9 facing the movable ring 5. An adjusting screw 10 is provided on the installation ring 3 corresponding to the position of the push rod 9, with the adjusting screw 10 facing the other end of the push rod 9. A screw seat 11 is provided on the installation ring 3, and the adjusting screw 10 passes through the installation ring 3 and connects to the screw seat 11. By turning the adjusting screw 10, the push rod 9 is lifted, thereby squeezing the movable ring 5, causing the sealing ring 7 between the movable ring 5 and the fixed ring 4 to be squeezed and deformed.

[0013] In this embodiment, the sealing ring 7 has a hollow structure inside. After being squeezed, the sealing ring 7 expands outward to improve the sealing performance between the packing and the tower wall.

[0014] An annular overflow groove 12 is provided on the inner side above the outer ring 1. The overflow groove 12 collects the liquid around the packing material. A liquid guiding groove 13 is connected inside the annular overflow groove 12. An overflow port 14 is provided on the overflow groove 12 and communicates with the liquid guiding groove 13. The overflow port 14 discharges the liquid into the liquid guiding groove 13. In this embodiment, four liquid guiding grooves are connected inside the overflow groove 12. A liquid collecting groove 15 is connected in the middle of the liquid guiding groove 13. The liquid collecting groove 15 is located in the middle of the packing body 2. The liquid in the liquid guiding groove 13 gathers into the liquid collecting groove 15. A drain pipe 16 is provided in the middle of the liquid collecting groove 15. The liquid in the liquid collecting groove 15 is discharged to the packing body 2 through the drain pipe 16.

[0015] 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.
