Description

Technical Field

[0001] The utility model belongs to the technical field of packed towers, and in particular relates to a packed tower capable of improving uniformity effect. Background Art

[0002] Packed towers have low fluid resistance and are suitable for processes with large gas volumes and small liquid volumes. Liquid flows downward along the surface of the packing, with the gas and liquid flowing in countercurrent or cocurrent, depending on the specific reaction. Packed towers contain relatively small amounts of liquid. Whether gas or liquid, the flow pattern within the tower resembles piston flow. If solids are generated during the reaction, a packed tower should not be used.

[0003] The packed tower is filled with fillers of various shapes (called packing) so that the liquid flows along the surface of the packing to form a liquid film, which is dispersed in the continuously flowing gas. The contact surface between the gas and liquid phases is on the liquid film surface of the packing.

[0004] The gas inside the packed tower enters the packed tower through the bottom of the packed tower. When the liquid drips faster or the liquid volume is larger, the liquid will enter the inside of the gas outlet pipe, so that the liquid will affect the speed at which the gas is discharged through the pipe.

The dimensions and proportions in the various drawings are for illustrative purposes only and should not be construed as limiting the present invention. These dimensions may be exaggerated relative to actual products.

[0028] Reference Figure 1-4 , a packed tower capable of improving uniformity, comprising a packed tower body 1, a guide plate 2 being provided inside the packed tower body 1, a connecting pipe 4 being provided on the top of the guide plate 2, a mounting hole 5 being provided inside the connecting pipe 4, and a pipe sealing structure 6 being provided on the inner wall of the mounting hole 5;

[0029] The pipeline sealing structure 6 includes an air inlet pipe 601 and a sliding shaft 602. A sealing block 603 is provided on the top of the sliding shaft 602. A through hole is opened in the middle of the sealing block 603. The sealing block 603 is set to be a truncated cone shape. The maximum diameter of the sealing block 603 is smaller than the diameter of the mounting hole 5.

[0030] Furthermore, in the above technical solution, a water outlet trough 3 is provided at the top of the packed tower body 1, and the number of the water outlet troughs 3 is set to be multiple. A connecting pipe 4 is provided between two of the water outlet troughs 3. After the liquid and the gas are mixed, the liquid flows into the interior of the water outlet trough 3 through the guide plate 2, and the liquid enters the bottom of the packed tower body 1 through the water outlet trough 3 for collection and discharge.

[0031] Furthermore, in the above technical solution, the longitudinal section of the guide plate 2 is set to be an isosceles triangle, the top of the guide plate 2 is aligned with the center point of the packed tower body 1, and the two sides of the top of the guide plate 2 are inclined to facilitate the discharge of liquid through the inclined guide plate 2 and avoid the accumulation of liquid on the top of the guide plate 2.

[0032] Furthermore, in the above technical solution, a support rod 8 is provided at the bottom of the water outlet trough 3 , and the support rod 8 is connected to the packing tower body 1 .

[0033] Furthermore, in the above technical solution, the inner wall of the mounting hole 5 is provided with a fitting ring 7, the inner side of the fitting ring 7 is fitted with the outer wall of the sealing block 603, the air inlet pipe 601 is provided at the bottom of the packing tower body 1, the air inlet pipe 601 is aligned with the mounting hole 5, the bottom of the air inlet pipe 601 is provided with a bottom plate 604, and a return spring 605 is provided between the bottom plate 604 and the packing tower body 1. When the packing tower body 1 needs to mix gas and liquid, the air pump sends gas into the interior of the air inlet pipe 601, and then the pressure inside the air inlet pipe 601 increases. The gas pushes the sealing block 603 out of the fitting ring 7 and a gap appears between the two. The sealing block 603 drives the sliding shaft 602 to move upward, and the sliding shaft 602 squeezes the bottom plate 604. Then the gas is discharged through the gap between the sealing block 603 and the fitting ring 7. At the same time, the dripping liquid fits with the top of the sealing block 603. The top of the sealing block 603 can be flat or tilted inward, so that the liquid can drip directly onto the surface of the guide plate 2, or the liquid can enter the inside of the through hole inside the sealing block 603 along the top of the tilted sealing block 603 and be discharged.

It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
