Description

Technical Field

[0001] The utility model relates to the technical field of packing tower equipment, and particularly relates to a tower packing structure with a self-cleaning function. Background Technique

[0002] Tower packing refers to the tower packing in a packing tower, which functions to provide a sufficient contact surface for gas and liquid phases and create conditions to improve their turbulence degree for mass transfer. The tower packing has a large gas-liquid contact surface, a high mass transfer coefficient, a large throughput and a small resistance. Therefore, it is required that the packing layer has a high porosity, a large specific surface area, good surface wetting performance, and is also structurally conducive to the close contact of the two phases to promote turbulence. The manufacturing material should be corrosion-resistant to the treated material and have a certain mechanical strength so that the bottom of the packing layer will not be broken or deformed due to pressure.

[0003] After the tower packing is used for a long time, a large amount of dirt will adhere to its surface. These dirt will reduce the contact surface between the tower packing and gas / liquid, and reduce the specific surface area and surface wetting performance of the packing layer. Therefore, it needs to be cleaned regularly. At present, the cleaning of the tower packing is basically to manually disassemble the tower packing layer from the packing tower and replace it with a new one, and the fouled packing layer is cleaned manually, which has a large workload, takes a long time, is time-consuming and laborious, and has low efficiency.

[0040] Embodiment: Refer to Figures 1-9 A tower packing structure with a self-cleaning function as shown, including a tower shell 1. One side of the tower shell 1 is fixedly connected and communicated with a cleaning bin 5, and a support assembly is rotatably connected inside the tower shell 1. A plurality of packing assemblies are fixedly installed inside the support assembly;

[0041] The support assembly includes two ring rails 18. A plurality of partition plates 17 are fixed between the two ring rails 18. A polygonal prism 16 is fixed inside the plurality of partition plates 17. Both ring rails 18 are rotatably connected to the inner side wall of the tower shell 1. The plurality of partition plates 17 are arranged in a circular array outside the polygonal prism 16, so that the plurality of packing assemblies can be evenly distributed outside the polygonal prism 16;

[0042] The packing assembly includes a back plate 20 and a plurality of packing frames 19 for filling tower packing. One end of each of the plurality of packing frames 19 is fixedly connected to the back plate 20. One side of the back plate 20 is detachably and fixedly connected to the side surface of the polygonal prism 16, and a traction plate 23 is fixed to the other side of the back plate 20;

[0043] There is a discharge port between the tower shell 1 and the cleaning bin 5. The design of the discharge port enables the packing frame 19 to pass through the tower shell 1 and enter the cleaning bin 5. An arc-shaped door 15 for closing the discharge port is slidably fitted on the outer side of the tower shell 1. A number of spray nozzles 12 are installed on the inner side of the cleaning bin 5. And a slide rod 7 slidably penetrates through one side of the cleaning bin 5. One end of the slide rod 7 is fixed with a pick-up box 13.

Hydraulic cylinders 9 are fixed on both side faces of the cleaning bin 5. The output end of the hydraulic cylinder 9 is fixedly connected with the back plate 8.

[0044] In the present utility model, when it is necessary to clean the tower packing in the packing frame 19, control the two ring tracks 18 on the support assembly to rotate synchronously by a specific angle, so that each packing assembly moves to the position between the tower shell 1 and the cleaning bin 5 one by one. When the packing assembly is located between the tower shell 1 and the cleaning bin 5, control the arc-shaped door 15 to slide, so that the discharge port between the tower shell 1 and the cleaning bin 5 is opened. Then control the hydraulic cylinder 9 to contract and drive the slide rod 7 to slide into the interior of the tower shell 1. The pick-up box 13 fixed at one end of the slide rod 7 approaches the traction plate 23. Control a set of clamping plates 14 in the pick-up box 13 to clamp both sides of the traction plate 23. Then control the hydraulic cylinder 9 to extend, and draw out the packing assembly from between the two partition plates 17 through the slide rod 7 and move it into the cleaning bin 5. Since the back plate 20 and the multi-prism 16 are detachably connected, the fixed connection between the back plate 20 and the multi-prism 16 will be disconnected under the action of an external force. When the packing frame 19 moves into the cleaning bin 5, the spray nozzles 12 will spray cleaning liquid at high speed towards the packing frame 19, so that the dirt on the tower packing inside it is washed away. After cleaning, the packing assembly is sent back to the initial position. After the cleaning is completed, the arc-shaped door 15 slides and closes the discharge port, thus realizing the automatic cleaning of the tower packing.

[0045] In order to be able to control the stable rotation of the two ring tracks 18 inside the tower shell 1, in this embodiment, two annular guide plates 2 are provided on the circumferential side of the tower shell 1.

An annular rack is fixed on the circumferential side of the ring track 18 at the top. The annular rack is meshed with the gear 28. A first servo motor 4 is fixedly installed on the top of the transmission box 3 through a bracket. The output shaft of the first servo motor 4 penetrates into the transmission box 3 and is meshed with the gear 28. By controlling the first servo motor 4 to start, the first servo motor 4 can drive the gear 28 fixed to its rotating shaft to rotate. This gear 28 will drive the annular rack meshed with it to rotate, thereby realizing the control of the rotation angle of the two ring tracks 18, so that each packing assembly can move to the position between the tower shell 1 and the cleaning bin 5 one by one.

The clamping plate 21 is clamped in the clamping groove 24. A number of iron blocks 25 are embedded at the position of the bottom of the clamping groove 24 corresponding to the permanent magnets 22. The clamping cooperation between the clamping plate 21 and the clamping groove 24 realizes the quick clamping and fixing of the packing component. Through the adsorption force of the permanent magnets 22 on the iron blocks 25, the clamping plate 21 can be more firmly fixed inside the clamping groove 24.

[0047] In order to control the closing and opening of the discharge port between the tower shell 1 and the cleaning bin 5, in this embodiment, an arc - shaped toothed plate 26 is provided on the arc - shaped door 15.

By driving the gear 28 connected thereto to rotate through the second servo - motor 27, due to the meshing connection between this gear 28 and the arc - shaped toothed plate 26, the arc - shaped door 15 can be pushed to slide along the relief groove on the side surface of the tower shell 1, thereby realizing the control of the closing and opening of the discharge port between the tower shell 1 and the cleaning bin 5.

[0048] In order to realize the cleaning operation of the tower packing in the packing frame 19 by the cleaning bin 5, in this embodiment, a sewage discharge pipe 11 is fixedly connected to the bottom of the cleaning bin 5.

Under the action of an external water pump, the cleaning water enters the water inlet pipe 10 and is distributed into the spray pipes 6. Finally, it is sprayed out through the spray heads 12. The high - speed water flow will wash away the dirt on the tower packing. The washed - away dirt falls to the bottom of the cleaning bin 5 and is discharged through the sewage discharge pipe 11.

[0049] In order to enable the pick - and - place box 13 to clamp and fix the traction plate 23, in this embodiment, a double - headed lead screw 29 is rotatably connected inside the pick - and - place box 13.

The clamping plates 14 are slidably sleeved outside the guide rods 30. By the third servo - motor 31, the rotation of the double - headed lead screw 29 inside the pick - and - place box 13 can be controlled. The two ends of the double - headed lead screw 29 are provided with threads in opposite directions. Through these two threads, the two clamping plates 14 can be driven to approach or move away from each other, so that the clamping plates 14 can stably clamp and fix the traction plate 23.

[0050] To improve the stability during the picking and placing of the packing components, further, there are multiple traction plates 23, and each traction plate 23 is located between adjacent packing frames 19. The number of sliding rods 7 is the same as that of the traction plates 23, and a picking and placing box 13 is fixed to one end of each sliding rod 7.
