Description

Technical Field

[0001] The utility model relates to the technical field of distillation tower filler equipment, in particular to a filler with an anti-leakage structure. Background Art

[0002] The function of the distillation tower packing is to provide sufficient contact surface for the gas and liquid phases, and to create conditions for increasing their turbulence level, so as to facilitate mass and heat transfer. The liquid distributor is an extremely critical internal component in the distillation tower, which not only affects the mass transfer efficiency of the packing, but also affects the operational elasticity of the packing. Its function is to uniformly distribute or redistribute the liquid at the top of the packing or at a certain height, so as to increase the effective surface for mass and heat transfer, improve the contact between phases, and thus improve the efficiency of the tower. If there is a gap between the distillation tower and the packing, part of the liquid released by the distributor will enter the bottom of the tower along the gap without contacting the packing, resulting in the overall efficiency of the distillation tower being affected. Therefore, those skilled in the art hereby propose a solution for packing with a leak-proof structure. Utility Model Content

[0024] In order to more clearly explain and illustrate the technical solution and implementation of the present invention, several preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0025] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its applications and uses. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various figures only schematically represent the concepts and principles of the embodiments of the present disclosure and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific figures may use exaggerated methods to illustrate the relevant details or structures of the embodiments of the present disclosure. The various publications, patents and published patent specifications cited herein are incorporated herein by reference in their entirety. The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention.

[0026] Embodiment: A preferred technical solution for a packing with a leak-proof structure includes the following:

[0027] Refer to the instruction manual Figure 1 As shown: it includes a packing member 1, the top area of ​​the outer ring surface of the packing member 1 is covered with a circle of leakage prevention member 2; the packing member 1 includes a stainless steel hoop 11, and a wire mesh corrugated packing 12 fixedly connected to the inner cavity of the stainless steel hoop 11;

[0028] Refer to the instruction manual Figure 3 As shown: the leakage prevention part 2 includes a hollow fluororubber ring 21, a wedge-shaped inner ring 22 fixed to the top area of ​​the inner ring of the hollow fluororubber ring 21, and a liner ring 25 fixedly connected to the top end face of the wedge-shaped inner ring 22, and 2-3 stainless steel tensioning rings 24 are embedded and tightened in the inner ring of the liner ring 25; 3 circles of fluororubber sealing rings 26 are fixedly connected to the outer ring surface of the hollow fluororubber ring 21, and an air nozzle 23 is provided on the top end face of the hollow fluororubber ring 21, wherein air can be injected or released into the interior of the hollow fluororubber ring 21 through the air nozzle 23, so that the expansion degree of the hollow fluororubber ring 21 can be changed in advance before the hollow fluororubber ring 21 is installed, so as to allow the outer ring surface of the hollow fluororubber ring 21 to contact the inner wall of the distillation tower, and the inner ring surface to contact the outer ring surface of the stainless steel hoop 11, thereby minimizing the distance between the filler 1 and the distillation tower.

[0029] Refer to the instruction manual Figure 3 As shown: the bottom area of ​​the outer ring surface of the stainless steel hoop 11 is connected to the inner wall of the distillation tower, a chamber for expansion / contraction is opened inside the hollow fluororubber ring 21, the fluororubber sealing rings 26 are arranged at equal distances from each other, the outer ring surface of the fluororubber sealing ring 26 is in close contact with the inner wall of the distillation tower, and the edge positions of the outer ring surface of the hollow fluororubber ring 21 are all chamfered.

[0030] Refer to the instruction manual Figure 3 As shown: the vertical section of the wedge-shaped inner ring 22 is a right triangle, and the inner surface of the wedge-shaped inner ring 22 has a downwardly inclined slope for guiding the liquid of the distributor to flow into the wire mesh corrugated packing 12. The bottom end face of the wedge-shaped inner ring 22 contacts the upper end face of the stainless steel hoop 11. A circle of grooves for the outer ring of the stainless steel tensioning ring 24 to be inserted and embedded is provided on the inner surface of the liner ring 25. A circular ring is fixedly connected to both ends of the stainless steel tensioning ring 24. Since the stainless steel tensioning ring 24 exerts an outward expansion force on the liner ring 25, the hollow fluororubber ring 21 is brought into contact with the inner wall of the distillation tower. When replacing the packing, the circular rings at the ends of the stainless steel tensioning ring 24 are used as force points. With the help of the two clamp arms of the pliers, the stainless steel tensioning ring 24 is deformed inwardly through the circular rings, and the air inside the hollow fluororubber ring 21 is released through the air nozzle 23, so that the hollow fluororubber ring 21 is deflated and the packing piece 1 is taken out.

[0031] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0032] The hollow fluororubber ring 21 is inserted into the upper surface of the stainless steel hoop 11, so that the upper end surface of the stainless steel hoop 11 contacts the bottom of the wedge-shaped inner ring 22. At the same time, the stainless steel hoop 11 is connected to the inner wall of the distillation tower. When the distributor sprays liquid onto the wire mesh corrugated packing 12, due to the high temperature of 100°C-150°C inside the distillation tower, the air inside the hollow fluororubber ring 21 is thermally expanded, causing the hollow fluororubber ring 21 to expand. At the same time, the outward tension of the stainless steel tension ring 24 pushes the liner ring 25 from the inside out. The outer surface of the liner ring 25 contacts the top area of ​​the inner surface of the hollow fluororubber ring 21, thereby making the hollow fluororubber ring 21 and the fluororubber sealing ring 26 tightly contact the inner wall of the distillation tower, forcing the liquid to escape by blocking the gap. The slope on the inner side of the wedge-shaped inner ring 22 guides the liquid into the wire mesh corrugated packing 12.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
