Description

Technical Field

[0001] The utility model belongs to the technical field of distillation tower accessories in fine chemical industry, and specifically relates to a high-efficiency distillation tower plate component. Background Art

[0002] A distillation tower is a tower-type gas-liquid contact device for distillation. It uses the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, to transfer the light components in the liquid phase to the gas phase, and the heavy components in the gas phase to the liquid phase, thereby achieving the purpose of separation.

[0003] The distillation tower plate assembly is the core component of the distillation tower. The distillation efficiency of the distillation tower depends entirely on the structure of the distillation tower plate assembly. However, the plates are prone to corrosion due to residual liquid on the surface. Therefore, it is necessary to regularly check whether the plates are corroded. If corrosion occurs, they need to be replaced.

[0004] However, currently available distillation tower plate assemblies are mostly fixedly installed inside the distillation tower using fixing bolts. Therefore, when disassembling and replacing the plates, workers still need to use professional tools to disassemble them, which makes disassembly and assembly very inconvenient. In view of this, the present utility model is specially proposed. Utility Model Content

[0008] Preferably, the elastic component comprises a spring, one end of which is fixedly connected to the inner wall of the groove, and the other end of which is fixedly connected to the limiting block.

[0009] In order to facilitate the disassembly of the tower plate body, the resetting component further includes a pull rope and a handle, the pull rope is fixedly connected to the limit block, and the handle is fixedly installed on one end of the pull rope passing through the connecting ring.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] Embodiment 1:

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A high-efficiency distillation tower plate assembly comprises a support ring 2 fixedly installed in the distillation tower, and also comprises: a connecting ring 1 connected to the support ring 2; a plate body 101 fixedly connected to the connecting ring 1; a plurality of positioning blocks 202 fixedly connected to the connecting ring 1 at equal intervals, wherein a fixing groove 201 corresponding to the positioning block 202 is provided on the support ring 2, the positioning block 202 is inserted into the fixing groove 201, grooves 203 are provided on both sides of the positioning block 202, and a limiting block 205 is slidably connected in the groove 203; an elastic component is arranged in the groove 203 and is used to push the limiting block 205 to move out of the groove 203 and be clamped on the lower surface of the support ring 2; a reset component is arranged on the connecting ring 1 and is used to pull the limiting block 205 to move into the groove 203 so as to release the limiting fixation on the plate body 101.

[0025] The elastic component includes a spring 204 , one end of which is fixedly connected to the inner wall of the groove 203 , and the other end of which is fixedly connected to the limit block 205 .

[0026] The reset component includes a pull rope 206 and a handle 207 . The pull rope 206 is fixedly connected to the limit block 205 , and the handle 207 is fixedly mounted on one end of the pull rope 206 that passes through the connecting ring 1 .

[0027] When assembling the distillation tower and the plate body 101, first put the plate body 101 into the distillation tower and move the plate body 101 downward. When the connecting ring 1 on the outer wall of the plate body 101 fits with the supporting ring 2 inside the distillation tower, the positioning block 202 is inserted into the fixing groove 201, so that the limiting block 205 is squeezed by the supporting ring 2 and slides into the groove 203, and compresses the spring 204 until the limiting block 205 is completely retracted into the groove 203. When the connecting ring 1 fits with the supporting ring 2 inside the distillation tower, the end of the positioning block 202 with the groove 203 moves out of the fixing groove 201, and then the compressed spring 204 generates a thrust to push the limiting block 205 to move out of the groove 203 and be clamped on the lower surface of the supporting ring 2, so as to achieve the limit fixing of the connecting ring 1, so that the staff can conveniently assemble the distillation tower and the plate body 101;

[0028] In summary, by limiting and fixing the connecting ring 1, the stability of the tray body 101 installed inside the distillation tower is improved;

[0029] When the tray body 101 needs to be disassembled and replaced, the staff pulls the pull rope 206 through the handle 207 to drive the limit block 205 to slide into the groove 203 and compress the spring 204 until the limit block 205 is completely retracted into the groove 203, thereby releasing the limit fixation of the connecting ring 1, and then the staff can take the tray body 101 out of the distillation tower;

[0030] In summary, the staff can conveniently disassemble and replace the tower plate body 101 without the aid of professional tools.

[0031] Embodiment 2:

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, a high-efficiency distillation tower plate assembly, which is basically the same as Example 1, and further, a plurality of spiral tubes 102 are fixedly installed in the plate body 101, and the two ends of the spiral tube 102 are respectively fixedly connected with a branch tube 103 and a branch tube 2 104, the end of the branch tube 103 away from the spiral tube 102 is parallel to the lower surface of the plate body 101, and the end of the branch tube 2 104 away from the spiral tube 102 is higher than the upper surface of the plate body 101, and the upper surface of the plate body 101 is provided with a guide hole 105 connected with the branch tube 2 104; when in use, the gas flows upward into the spiral tube 102 through the branch tube 103, and then the liquid is dripped on the upper surface of the plate body 101. At this time, the liquid flows downward through the guide hole 105 and flows into the spiral tube 102, so that the liquid and the gas circulate in the spiral tube 102, thereby extending the contact time between the gas and the liquid, thereby ensuring sufficient contact between the gas and the liquid, and improving the distillation effect.

[0033] Embodiment 3:

[0034] Reference Figure 5 , a high-efficiency distillation tower plate assembly, which is basically the same as Example 1, and further, the side of the limit block 205 that is in contact with the support ring 2 is arranged in a plane, which can be used to enable the limit block 205 to firmly limit and fix the connecting ring 1 on the support ring 2 when the connecting ring 1 is in contact with the support ring 2, thereby improving the stability of the tower plate body 101, and the side of the limit block 205 away from the support ring 2 is arranged at an angle, so that the limit block 205 can be prevented from being too long and affecting the smooth insertion of the positioning block 202 into the fixing groove 201.

[0035] Embodiment 4:

[0036] Reference Figure 1 , Figure 2 , a high-efficiency distillation tower tray assembly, which is basically the same as Example 1, and further, a fixing ring 3 is fixedly connected to the tray body 101, and a sealing ring 301 is fixedly installed on the outer wall of the fixing ring 3, and the sealing ring 301 is in contact with the inner wall of the support ring 2; after the installation of the tray body 101 is completed, the fixing ring 3 inserted into the support ring 2 squeezes the sealing ring 301 to fit closely with the inner wall of the support ring 2, thereby increasing the sealing performance of the connection between the tray body 101 and the support ring 2, preventing gas from leaking through the gap between the tray body 101 and the support ring 2, resulting in insufficient contact between the gas and the liquid, and reducing the distillation effect.
