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.

[0031] See also Figures 1 to 7 , the utility model provides a technical solution:

[0032] A distillation tower convenient for cleaning and maintenance comprises a tower body 1, a maintenance cover 2 is bolted to the top and bottom of the tower body 1, a packing mechanism 3 convenient for disassembly and maintenance is arranged in the middle of the tower body 1, and a limited support mechanism 4 is arranged on the side wall of the tower body 1;

[0033] The filling mechanism 3 includes a connecting assembly 31 and an air flow conveying assembly 32. The connecting assembly 31 includes a tower plate 311, a downcomer 312, a connecting screw 313 and a limiting nut 314. Multiple tower plates 311 are arranged inside the tower body 1, the downcomer 312 is arranged on the side wall of the tower plate 311, four connecting screws 313 are movably arranged in the middle of the tower plate 311, and multiple limiting nuts 314 are threadedly connected to the side walls of the connecting screw 313. Limiting nuts 314 are arranged on both sides of the tower plate 311.

[0034] Specifically, Figure 5 As shown, the airflow conveying assembly 32 includes an air outlet pipe 321, a connecting frame 322, a connecting screw 323, a bubble outlet cover 324 and an air outlet groove 325. A plurality of air outlet pipes 321 are arranged at equal intervals in the middle of the tower plate 311. The connecting frame 322 is fixedly connected to the inner wall of the air outlet pipe 321. The connecting screw 323 is threadedly connected to the middle of the connecting frame 322. The bubble outlet cover 324 is fixedly connected to the side wall of the connecting screw 323. The bubble outlet cover 324 is sleeved on the outside of the air outlet pipe 321. A plurality of air outlet grooves 325 are opened on the side wall of the bubble outlet cover 324.

[0035] Specifically, Figure 4 As shown, a liquid receiving tank 6 is provided at one end of the tower plate 311 away from the downcomer 312 , and the top surface of the liquid receiving tank 6 is located below the top surface of the tower plate 311 .

[0036] Specifically, Figure 4 As shown, the top of the downcomer 312 is fixedly connected with an overflow weir 7 , and the height of the overflow weir 7 is higher than the height of the tower plate 311 .

[0037] When in use, the two ends of the tower body 1 can be disassembled, inspected and cleaned by disassembling the inspection cover 2. The multiple tower plates 311 can be assembled and combined by connecting the screw rod 313 and the limit nut 314. The multiple groups of tower plates 311 can be installed and supported inside the tower body 1 by the limit support mechanism 4. The tower plates 311 can be disassembled, inspected and cleaned by the movable connection between the multiple groups of tower plates 311 and the tower body 1. When the tower plate 311 transports the gas-liquid phase, the liquid receiving tank 6 can buffer the liquid falling on the tower plate 311, and the overflow weir 7 can buffer the liquid.

The two side walls of the supporting low ring 42 are in contact with the tower body 1 and the inspection cover 2 respectively.

[0039] Specifically, Figure 6 As shown, a plurality of mounting screws 5 are embedded on the side wall of the supporting lower ring 42 , and the mounting screws 5 are threadedly connected to the tower body 1 .

[0041] Specifically, Figure 7 As shown, the cross sections of the limiting block 8 and the limiting groove 9 are both conical.

[0042] When in use, first the limiting ring 41 limits the top tower plate 311, and the tower plate 311 can be limited by the plug-in cooperation of the limiting block 8 and the limiting groove 9 to prevent the tower plate 311 from rotational displacement, and the bottom tower plate 311 can be supported and limited by the supporting low ring 42, and the supporting low ring 42 can be limited and supported by the connection between the inspection cover 2 and the tower body 1, and the supporting low ring 42 can be auxiliary installed by installing the screws 5, so that multiple groups of tower plates 311 can be supported and limited inside the tower body 1.
