Description

Technical Field

[0001] The utility model relates to the technical field of stripping tower equipment, in particular to a detachable heat-insulating kit for a stripping tower delivery pipeline. Background Art

[0002] Stripping is a unit operation used to recover the absorbed solute and separate the absorbent from the solute to obtain regeneration. Stripping can be used in conjunction with absorption or alone. The stripping tower can be in the form of a plate tower or a packed tower. Regardless of the form of the tower, the raw materials enter the tower from the top and leave the tower from the bottom; the desorbent enters the tower from the bottom, contacts the liquid raw material in countercurrent in the tower, and leaves the tower at the top of the tower together with the stripped components. In contrast to the absorption tower, the concentrated end is at the top of the tower and the dilute end is at the bottom of the tower. In the stripping tower, the equilibrium partial pressure of the solute in the liquid phase is greater than the partial pressure of the solute in the gas phase. During the stripping process, the solute molecules need to be phase-changed into gas, so it is an endothermic process. Therefore, the temperature of the stripping agent is generally equal to or greater than the raw material temperature, otherwise the stripping effect will be reduced.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a detachable insulation kit for a stripping tower delivery pipeline, comprising two insulation components with the same structure, wherein the insulation components comprise an inner insulation sleeve 1, a sealing sheet 4 and an outer isolation sleeve 2. When the insulation kit is in use, the inner insulation sleeve 1 is in direct contact with the outer surface of the stripping tower delivery pipeline, the sealing sheet 4 is used to seal the direct seam between the two insulation components, thereby improving the insulation performance of the insulation sleeve connection, and the insulation sleeve connection is in contact with the support platform of the stripping tower delivery pipeline through the outer isolation sleeve 2, thereby reducing the contact area between the insulation kit and the support platform, thereby reducing the heat transfer efficiency of the insulation kit.

[0027] The inner thermal insulation sleeve 1 includes a reinforcement layer 19, an outer protective sleeve 18 is fixed to the outer surface of the reinforcement layer 19, a vacuum layer 20 is fixed to the inner wall of the reinforcement layer 19, and a thermal insulation layer 21 is fixed to the inner wall of the vacuum layer 20. Through the arrangement of the structure of the inner thermal insulation sleeve 1, the outer protective sleeve 18 can protect the reinforcement layer 19, reduce the force applied by external force on the reinforcement layer 19, and extend the service life of the reinforcement layer 19. Through the arrangement of the vacuum layer 20, the heat transfer efficiency between the thermal insulation layer 21 and the reinforcement layer 19 can be reduced, and the thermal insulation effect of the inner thermal insulation sleeve 1 is improved.

[0028] In some embodiments of the present application, the material of the reinforcing layer 19 may be a metal alloy to improve the strength of the inner insulation sleeve 1, and the material of the outer protective sleeve 18 may be rubber; the vacuum layer 20 may be a polyurethane foam vacuum insulation layer disclosed in the authorized patent with application number CN200620164511.8; the material of the insulation layer 21 may be insulation cotton.

[0029] The outer surface of the inner insulation sleeve 1 is fixedly connected to the outer isolation sleeve 2, one end of the outer isolation sleeve 2 is movably connected to a ball screw 9, the outer ring of the ball screw 9 is threadedly connected to a ball nut, and the outer ring of the ball nut is fixedly connected to a fixed tube 10. Through the setting of the ball screw 9, the rotation of the ball screw 9 allows the ball nut to move in the direction of the ball screw 9, and when the ball nut moves, it can drive the fixed tube 10 fixedly connected to it to move.

[0030] In some embodiments of the present application, outer isolation sleeves 2 are fixed to both ends of the inner insulation sleeve 1, so that the insulation assembly can be force-balanced, which is convenient for use of the insulation assembly. In this embodiment, the ball screw 9 is a bidirectional ball screw, and both ends of the bidirectional ball screw are threadedly connected with ball nuts.

[0031] The other end of the fixed tube 10 is provided with a plug hole, and the other end of the outer isolation sleeve 2 is fixedly connected with a sealing box 11, and a clamping structure adapted to the plug hole is provided in the inner cavity of the sealing box 11. The clamping structure includes an insert block 12 adapted to the plug hole and a blocking block 17. The middle part of the sealing box 11 is provided with a groove adapted to the fixed tube 10, and under the action of the ball screw 9, the fixed tube 10 can enter and exit the groove.

[0032] One side of the groove near one end of the fixed tube 10 is connected with an insert block 12 through a spring 13. The insert block 12 is movably connected to the inner cavity of the sealing box 11. The insert block 12 and the fixed tube 10 are in a mutually perpendicular state. When the socket moves to the moving direction of the insert block 12, under the action of the rebound force of the spring 13, the insert block 12 can be inserted into the socket, and the position of the fixed tube 10 can be fixed, thereby realizing the rapid fixation of the two outer isolation sleeves 2, and avoiding the rotation of the ball screw 9, thereby improving the reliability of the fixation of the two outer isolation sleeves 2.

[0033] The end of the plug block 12 away from the groove is fixedly connected with a pull rod 14, the other end of the pull rod 14 penetrates the sealing box 11 and extends to the outside of the sealing box 11, the pull rod 14 is movably connected to the sealing box 11, and the other end of the pull rod 14 is movably connected to a pull handle 15. Through the setting of the pull handle 15, the user can drive the plug block 12 to move through the pull handle 15, and the plug block 12 can be separated from the socket under the action of external force.

[0034] A limit block 22 for limiting the pull handle 15 is fixed at one end of the sealing box 11. When the insert block 12 is separated from the fixed tube 10, the user rotates the pull handle 15, and the limit block 22 can limit the pull handle 15. At this time, the position of the insert block 12 remains unchanged, and the user can remove the restriction on the pull handle 15, freeing the user's hands and facilitating the user to rotate the ball screw 9.

[0035] A blocking block 17 is connected to the inner cavity of the other end of the groove through a second spring 16. The blocking block 17 is movably connected to the inner cavity of the groove, and the blocking block 17 is in the same straight line as the fixed tube 10. Through the setting of the blocking block 17, when the fixed tube 10 is inserted into the groove, the fixed tube 10 can squeeze the blocking block 17, so that the blocking block 17 gradually moves away from the plug-in block 12. When the fixed tube 10 moves away from the groove, the rebound force of the second spring 16 drives the blocking block 17 to move, so that the blocking block 17 can limit the plug-in block 12 to prevent the plug-in block 12 from entering the groove.

[0036] From the above description of the snap-fit ​​structure, it can be seen that during the process of inserting the fixing tube 10 into the groove, the plug block 12 can be inserted into the plug hole under the action of the rebound force of the spring 13, so as to realize the rapid fixation of the two outer isolation sleeves 2; and when the fixing tube 10 is away from the groove, the blocking block 17 can limit the plug block 12, so as to facilitate the rapid reconnection of the insulation sleeve.

[0037] The inner wall of the outer insulation sleeve 2 is fixed with a slide rail 3, and a slider is movably connected in the inner cavity of the slide rail 3. A sealing sheet 4 is fixed to the inner wall of the slider. The sealing sheet 4 is in a movably connected state with the inner insulation sleeve 1. Through the setting of the slide rail 3 and the slider, the sealing sheet 4 can move on the outer wall of the inner insulation sleeve 1, and the sealing sheet 4 is always in a fit state with the inner insulation sleeve 1 during the movement. When the insulation sleeve is in use, two sealing sheets 4 can be used to seal the seams of the two inner insulation sleeves 1, and the material of the sealing sheet 4 in this application is the same as that of the inner insulation sleeve 1.

[0038] One end of the inner insulation sleeve 1 is fixedly connected to a fixing block 8, and the end of the sealing sheet 4 away from the fixing block 8 is fixed with a fixing sheet 5 adapted to the fixing block 8. The inner diameter of the fixing sheet 5 is the same as the outer diameter of the fixing block 8. Through the arrangement of the fixing sheet 5 and the fixing block 8, the sealing sheet 4 on one insulation component can be fixed to another insulation component, so that the joint of the two insulation components can be sealed by the sealing sheet 4.

[0039] One end of the sealing sheet 4 is fixedly connected to an outer fixing ring 6, and the other end of the sealing sheet 4 is fixedly connected to an inner fixing ring 7. The inner diameter of the inner fixing ring 7 is the same as the outer diameter of the inner insulation sleeve 1, and one end of the inner fixing ring 7 connected to the sealing sheet 4 is movably connected to the inner insulation sleeve 1. The inner diameter of the outer fixing ring 6 is the same as the outer diameter of the inner fixing ring 7, and the outer diameter of the outer fixing ring 6 is smaller than the inner diameter of the outer insulation sleeve 2. By setting the inner fixing ring 7 and the outer fixing ring 6, the joints of two adjacent insulation sleeves can be sealed, thereby improving the insulation performance of the insulation sleeve when in use. In some embodiments of the present application, the material of the inner fixing ring 7 is the same as that of the inner insulation sleeve 1.

[0040] To sum up: when the detachable insulation kit for the steam stripping tower conveying pipeline is used, the user aligns the two insulation components and rotates the ball screw 9. The rotation of the ball screw 9 causes the ball nut threadedly connected thereto to move in the direction of the ball screw 9, and the ball nut drives the fixed tube 10 connected thereto to move, and the fixed tube 10 is gradually inserted into the inner cavity of the groove. During the movement of the fixed tube 10 in the inner cavity of the groove, the fixed tube 10 squeezes the blocking block 17, and the blocking block 17 gradually moves away from the plug block 12, and the insertion hole on the fixed tube 10 gradually approaches the plug block 12. When the insertion hole moves to the straight line where the plug block 12 is located, under the action of the rebound force of the spring 13, the plug block 12 is inserted into the insertion hole to fix the position of the fixed tube 10. At this time, the two outer isolation sleeves 2 are fixed, and then the two insulation components are fixed. After the insulation component is fixed, the user rotates the two sealing sheets 4, and the sealing sheets 4 drive the fixed sheets 5 fixedly connected thereto to move until the fixed sheets 5 move to the fixed block 8, and use tools such as bolts or Velcro to fix the fixed sheets 5 and the fixed block 8 together, so that the position of the sealing sheets 4 is fixed, and the sealing sheets 4 seal the seams of the two insulation components to improve the insulation performance of the insulation kit.

[0041] When the insulation sleeve needs to be removed, the user first releases the fixation of the fixing plate 5 and the fixing block 8, and then pulls the handle 15 outward until the handle 15 can no longer move. At this time, the handle 15 drives the plug block 12 to move through the pull rod 14, and the plug block 12 is separated from the socket. The user rotates the handle 15 to change the handle 15 from a vertical state to a horizontal state. At this time, the end of the handle 15 away from the pull rod 14 can contact the side wall of the limit block 22. The limit block 22 limits the handle 15. The user rotates the ball screw 9 to separate the fixing tube 10 from the sealing box, thereby realizing the removal of the two insulation components.
