Description

Technical Field

[0001] The utility model relates to the technical field of olefin separation, in particular to a water-washing stripping tower for olefin separation. Background Art

[0002] The methanol-to-olefins process uses methanol as a raw material to produce light olefins, creating a new way to produce light olefins from coal. However, while producing light olefin products, it also produces about 56% water and a small amount of oily waxes. In addition, fine catalyst powder is also entrained in the reaction products of the fluidized bed reactor. In industry, a water washing system is usually used to remove these impurities, which requires the use of a water-washing water stripping tower.

[0003] The existing water-washing water stripping tower needs to be cleaned after long-term use. When cleaning most of the existing water-washing water stripping towers, the chassis needs to be opened manually and then cleaned with a high-pressure water gun, which makes the cleaning of the water-washing water stripping tower very time-consuming and labor-intensive, and difficult to clean thoroughly. Therefore, we propose a water-washing water stripping tower for olefin separation. Utility Model Content

It also includes a reset component 4, which includes an L-shaped connecting rod 41, a connecting plate 42, an extrusion column 43, a fixing ring 44 and a spring 45. The lower end of the circumference of the fixing tube 34 is fixed with an L-shaped connecting rod 41, and the lower end of the L-shaped connecting rod 41 is fixed with an extrusion column 43. The surface of the L-shaped connecting rod 41 is fixed with a connecting plate 42. All the connecting plates 42 are fixed to the two swivels. Inside the ring 32, a fixing ring 44 is fixed on the circumferential surface of the L-shaped connecting rod 41, and a spring 45 is sleeved on the circumferential surface of the L-shaped connecting rod 41. The upper end of the spring 45 is fixed to the lower side of the connecting plate 42, and the lower end of the spring 45 is fixed to the upper end of the fixing ring 44. The extrusion assembly 5 includes an extrusion ring 51 and an extrusion head 52. Two corresponding extrusion rings 51 are fixed inside the tower body 1. The two extrusion rings 51 are respectively located at the lower ends of the two connecting rings 31. The upper ends of the extrusion rings 51 are fixed with evenly distributed extrusion heads 52. All the extrusion heads 52 are located between all the extrusion columns 43. The dynamic component 6 includes a motor 61, a gear 62 and a gear ring 63. The motor 61 is installed on the upper end of the connecting ring 31. The gear 62 is fixed to the output shaft of the motor 61. The gear ring 63 is fixed to the upper end of the rotating ring 32. The gear 62 is meshed with the gear ring 63. The input end of the motor 61 is electrically connected to the output end of the external control switch group. The two connecting rings 31 are driven to rotate by the rotating component 6. All the extrusion columns 43 are squeezed by the extrusion component 5. The fixed pipe 34 is reset by the reset component 4. The water outlet component 3 is used to spray water evenly into the interior of the tower body 1.

[0022] Water injection assembly 2: includes a water outlet pipe 21, a water tank 22, a water pump 23, a tee pipe 24 and a filter screen 25. The water outlet pipe 21 is fixed inside the water outlet set at the lower end of the tower body 1 surface. The left end of the water outlet pipe 21 is fixed inside the reflux port set on the right side of the water tank 22. A water pump 23 is installed inside the water tank 22.

[0023] The working principle of a water-washing stripping tower for olefin separation provided by the present invention is as follows: when it is necessary to clean the interior of the tower body 1, the water pump 23 can be started to inject water into the annular groove inside the two connecting rings 31 through the tee pipe 24, and then sprayed to the interior of the tower body 1 through all the fixed pipes 34. At this time, the two motors 61 are started to rotate the two gears 62, and the rotation of the two gears 62 drives the gear ring 63 to rotate. The rotation of the two gear rings 63 causes the two rotating rings 32 to rotate. During the rotation of the two rotating rings 32, all the fixed pipes 34 will be driven to rotate. During the rotation of all the fixed pipes 34, all the L-shaped connecting rods 41 will be driven to rotate. The extrusion columns 43 move in a row, and in the process of their movement, all the extrusion columns 43 will be driven to move. When all the extrusion columns 43 are moving, when they come into contact with the extrusion head 52, they will drive the extrusion columns 43 to move upward under the action of the extrusion head 52. When the extrusion columns 43 are away from the extrusion head 52, the extrusion columns 43 will reset downward under the action of the spring 45. Continuous rotation of all the extrusion columns 43 will reciprocate up and down under the action of all the extrusion heads 52. The up and down reciprocating motion of all the extrusion columns 43 drives all the fixed pipes 34 to reciprocate up and down. In this case, water can be evenly sprayed to the interior of the tower body 1 to clean the interior, which is extremely convenient.
