Description

Technical Field

[0001] The utility model relates to the technical field of packed towers, in particular to a packed tower with a multi-stage variable speed rotation function. Background Art

[0002] A packed tower is a type of tower equipment primarily used in processes such as gas absorption, distillation, and extraction. Packed towers are filled with packing of a certain height. This packing provides ample contact surface between the gas and liquid phases and increases turbulence, facilitating mass transfer (including heat transfer). Liquid flows downward along the packing surface, while the gas and liquid flow in countercurrent or cocurrent, depending on the specific reaction process. The packing within a packed tower can be of various shapes, such as Raschig rings and Pall rings. These packings form a liquid film on their surface, dispersing it within the continuously flowing gas, thereby achieving effective contact between the gas and liquid phases.

[0003] Patent No. CN213286150U discloses a spray tower with mechanical rotating packing, which can effectively prevent scaling of the spray tower packing and ensure long-term heat exchange efficiency. It includes a spray tower main body, and a sprayer is arranged inside the spray tower main body; a connecting shaft is arranged inside the spray tower main body in a horizontally rotatable manner, and a rotating packing frame is arranged on the connecting shaft, and lightweight packing balls are installed inside the rotating packing frame. A rotating motor for driving the connecting shaft is arranged outside the spray tower main body.

[0004] However, the above-mentioned spray tower with mechanical rotating filler still has the following disadvantages:

[0005] Since the packing will experience problems such as aging, scaling, and sinking after a period of use, which will affect the heat exchange effect of the packing, the packing needs to be replaced regularly. However, the rotating packing frame and the stirring rod in the above-mentioned device restrict each other and are difficult to disassemble, making the packing replacement more difficult. In view of this, we propose a packing tower with a multi-stage variable speed rotation function. Utility Model Content

Therefore, the packing needs to be replaced regularly. However, in the above-mentioned device, the rotating packing frame and the stirring rod restrict each other and are difficult to disassemble, which increases the difficulty of packing replacement.

The movable end of the multi-stage variable speed motor is connected to a shaft. The end of the shaft away from the multi-stage variable speed motor is provided with a driving gear. A driven gear disc is meshed with the outside of the driving gear. A rotating shaft is fixed to the top of the driven gear disc, and a number of stirring rods are evenly distributed outside the rotating shaft.

[0011] Preferably, the rotating shaft passes through the middle of the filler support plate, and the rotating shaft forms a transmission structure through a driven gear plate, a driving gear, a shaft and a multi-stage speed-changing motor.

[0012] Preferably, the limiting structure includes a slide groove, a group of the slide grooves are symmetrically opened inside the positioning frame, a bending rod is inserted into the slide groove, a limiting ring plate is fixedly sleeved on the outside of the bending rod, a spring is connected to one side of the limiting ring plate, a guide rod is inserted into the bending rod, and a group of the guide rods are symmetrically fixed to the inner wall of the packing tower body.

The rotating stirring rod causes the fillers to collide and rub against each other, forming a three-phase fluid mixing mode of liquid, solid and gas, thereby enhancing heat exchange. At the same time, the dust particles in the gas are efficiently intercepted and gathered into large particles that fall into the bottom of the tower with the liquid.

At this time, the packing support plate and the limit frame can be quickly separated, which is convenient for replacing the packing between the packing support plate and the limit frame. Thereafter, when the bending rod is continued to be moved toward the inner wall of the packing tower body, the end of the bending rod can be moved out of the packing support plate. At this time, the packing support plate can also be disassembled for easy maintenance. Similarly, when the bending rod is moved as a whole into the slide groove, it does not affect the packing frame assembly itself and the assembly between the packing frame assembly and the positioning frame. Thereafter, the bending rod is released, and under the influence of the spring rebound force, the end of the bending rod pops out and effectively engages in the packing frame assembly, thereby realizing rapid limitation of the packing frame assembly.

[0028] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0029] A packed tower with multi-stage variable speed rotation function, see Figures 1 to 6 , including a packing tower body 1, a bracket 2 is fixedly sleeved on the outside of the packing tower body 1, an air inlet 3 is provided on the right side of the surface of the packing tower body 1, an air outlet 4 is provided on the top of the packing tower body 1, a liquid inlet 5 is provided on the left side of the surface of the packing tower body 1, a liquid outlet 6 is provided at the bottom of the packing tower body 1, a driving assembly 7 is provided above the air inlet 3, a positioning frame 8 is fixedly connected to the inside of the packing tower body 1, a packing frame assembly 9 is provided inside the positioning frame 8, and a group of limiting structures 10 are symmetrically provided on both sides of the positioning frame 8.

[0030] It is worth noting that the filling frame assembly 9 includes a filling support plate 901, which is engaged with the inside of the positioning frame 8. A group of blocking blocks 902 are symmetrically fixed on the outside of the filling support plate 901, and a group of limiting grooves 903 are symmetrically opened on the inside of the filling support plate 901. A limiting frame 904 is engaged with the inside of the filling support plate 901, and a group of limiting blocks 905 are symmetrically fixed on the outside of the limiting frame 904, wherein the limiting frame 904 forms a locking structure with the limiting groove 903 through the limiting blocks 905, and the limiting groove 903 and the filling support plate 901 are integrally formed, and the filling support plate 901 forms a locking structure with the positioning frame 8 through the blocking blocks 902. In the present invention, the detachable structure between the filler support plate 901 and the limit frame 904 facilitates the replacement of the internal filler, and the cooperation between the limit groove 903 and the limit block 905 facilitates the rapid assembly between the filler support plate 901 and the limit frame 904. The setting of the clamping block 902 serves as a guide, making it convenient for the filler support plate 901 to be quickly clamped into the positioning frame 8, and at the same time facilitating the precise positioning of the filler support plate 901 and the limit block 905 by the limit structure 10.

[0031] It is worth noting that the drive assembly 7 includes a fixed frame 701, which is fixed to the outer surface of the packing tower body 1. A multi-stage variable speed motor 702 is provided inside the fixed frame 701. The movable end of the multi-stage variable speed motor 702 is connected to a shaft 703. The end of the shaft 703 away from the multi-stage variable speed motor 702 is provided with a driving gear 704. The driving gear 704 is meshed with a driven gear disc 705 on the outside. A rotating shaft 706 is fixed to the top of the driven gear disc 705, wherein the rotating shaft 706 passes through the middle of the packing support plate 901. The rotating shaft 706 forms a transmission structure with the driven gear disc 705, the driving gear 704, the shaft 703 and the multi-stage variable speed motor 702. A number of stirring rods 707 are evenly distributed on the outside of the rotating shaft 706. In the present invention, the multi-stage variable speed motor 702 effectively drives the shaft 703 and the driving gear 704 to rotate, thereby driving the driven gear plate 705 on the upper side of the driving gear 704 to rotate, and then the rotating shaft 706 and the stirring rod 707 at the upper end of the driven gear plate 705 rotate. The rotating stirring rod 707 causes the fillers to collide and rub against each other, forming a three-phase fluid mixing mode of liquid, solid and gas, thereby enhancing heat exchange. At the same time, the dust particles in the gas are efficiently intercepted and gathered into large particles that fall into the bottom of the tower with the liquid.

[0032] It is worth emphasizing that the limiting structure 10 includes a slide groove 1001, a group of slide grooves 1001 are symmetrically opened inside the positioning frame 8, a bending rod 1002 is inserted into the slide groove 1001, and the bending rod 1002 is fixedly sleeved on the outside of the limiting ring plate 1003, and a spring 1004 is connected to one side of the limiting ring plate 1003, wherein the bending rod 1002 forms an elastic structure with the slide groove 1001 through the limiting ring plate 1003, the spring 1004, and the lateral end of the bending rod 1002 passes through the side of the packing support plate 901 and is stuck in the limit block 905, and a guide rod 1005 is inserted into the bending rod 1002, and a group of guide rods 1005 are symmetrically fixed to the inner wall of the packing tower body 1. When the packing box 901 is in the closed position, the packing box 902 is in the closed position, and the packing box 902 is in the closed position, so that the packing box 901 can be quickly separated from the packing box 901.

[0033] Working principle: When in use, the flue gas flows upward from the air inlet 3 and performs countercurrent contact heat exchange with the liquid water from the liquid inlet 5. At this time, the temperature of the flue gas decreases and the humidity increases. The dust, impurities, etc. in the flue gas are dissolved and washed by water, and the flue gas is purified. The purified flue gas is discharged into the atmosphere from the air outlet 4. The flue gas and liquid water merge in the filler frame assembly 9. The multi-stage variable speed motor 702 drives the shaft 703 and the driving gear 704 to rotate, thereby driving the driven gear plate 705 on the upper side of the driving gear 704 to rotate, and then the rotating shaft 706 and the stirring rod 707 at the upper end of the driven gear plate 705 rotate. The rotating stirring rod 707 causes the fillers to collide and rub against each other, forming a three-phase fluid mixing mode of liquid, solid and gas, thereby enhancing heat exchange. At the same time, the dust and impurity particles in the gas are high The packing is effectively intercepted and gathered into large particles that fall into the bottom of the tower with the liquid. When the packing needs to be replaced later, the bending rod 1002 is moved toward the inner wall of the packing tower body 1 so that the end of the bending rod 1002 is separated from the limit block 905. At this time, the packing support plate 901 and the limit frame 904 can be quickly separated, which is convenient for replacing the packing between the packing support plate 901 and the limit frame 904. After replacing the packing, the end of the bending rod 1002 is moved into the packing support plate 901. At this time, the packing support plate 901 and the limit frame 904 are quickly assembled through the cooperation between the limit groove 903 and the limit block 905. Then the bending rod 1002 is released, and under the influence of the rebound force of the spring 1004, the end of the bending rod 1002 pops out and engages in the packing frame assembly 9, thereby realizing rapid limitation of the packing frame assembly 9.
