Description

Technical Field

[0001] The invention relates to the technical field of liquid redistributors, in particular to a supporting device for collecting and redistributing liquids in a large tower. Background Art

[0002] The liquid collection and redistributor is a key device in the packed tower. Its main function is to redistribute the liquid to ensure that the liquid can flow evenly through the packing layer, thereby improving the mass transfer and heat transfer efficiency.

[0003] For large packed towers, especially those with a diameter of more than three meters, the area of ​​the liquid collection and redistributor inside the packed tower is large due to the large diameter of the packed tower. Due to the large area of ​​the distributor, the distributor is easily deformed under the action of gravity, resulting in an uneven bottom of the distributor. If the bottom of the distributor is uneven, the liquid will concentrate in the area with low levelness, resulting in uneven liquid redistribution. Therefore, in order to ensure the horizontality of the distributor, the posture of the distributor must be adjusted.

[0004] At present, the method of adjusting the distributor's posture is mostly to set a support beam at the bottom of the distributor, but the area of ​​the support beam will block the liquid distribution of the distributor, including the rising gas will also be affected to a certain extent, which needs to be improved. Summary of the invention

[0005] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a support device for a collector and redistributor in a large tower.

[0007] Furthermore, the distributor includes a base plate, on which a plurality of riser pipes are arranged, and a liquid collecting angle steel is arranged above each riser pipe. The upper pipe opening of the riser pipe is spaced apart from the liquid collecting angle steel, so that riser outlets are formed on both sides above the riser pipe; the beam frame spacing is arranged above the liquid collecting angle steel.

[0011] Furthermore, two supporting plates are arranged opposite to each other on the inner wall of the packing tower; the three beams on the beam frame are divided into two bottom beams and one top beam, and the two ends of the bottom beam are fixedly overlapped on the two supporting plates respectively.

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] As attached Figures 1 to 4 The supporting device of the large-scale tower collecting and redistributor includes a distributor 1 arranged in a packed tower. In order to ensure the horizontality of the distributor 1, a beam must be provided to support the bottom of the distributor 1 so that it is kept on the same horizontal plane. However, if a supporting beam is provided, it is usually placed at the bottom of the distributor 1, and the area of ​​the beam will block the liquid distribution of the distributor 1, including the rising gas will be affected to a certain extent.

[0026] Therefore, in the present invention, a beam frame 2 is further provided in the packing tower, and the beam frame 2 is correspondingly located above the distributor 1, so that the beam frame 2 will not affect the liquid distribution of the distributor 1. There are multiple leveling hanging assemblies 3 extending downward on the beam frame 2, and the lower end of the leveling hanging assembly 3 is connected to the distributor 1. The upper end of the leveling hanging assembly 3 is movably connected to the beam frame 2, so that the height of the leveling hanging assembly 3 is adjustable. Multiple leveling hanging assemblies 3 are respectively connected to different positions of the distributor 1. By adjusting the height of the multiple leveling hanging assemblies 3, the posture of the distributor 1 can be adjusted, and then the distributor 1 can be leveled.

[0027] The supporting device of the present invention is composed of a beam frame 2 and a leveling suspension assembly 3, and is suitable for large-scale filling towers of more than three meters and less than ten meters. As the diameter of the filling tower changes, the number of leveling suspension assemblies 3 arranged on the beam frame 2 can be adjusted accordingly.

[0028] As attached Figure 1 and 4As shown in , the distributor 1 is a trough-type liquid collecting and redistributing device 1, and the distributor 1 includes a bottom plate 4, on which a plurality of riser pipes 5 are arranged, and the riser pipes 5 are vertically penetrating pipes, and the interior of the riser pipes 5 is a gas ascending channel, and the lower end of the riser pipes 5 is fixedly connected to the bottom plate 4, and a liquid collecting angle steel 6 is arranged above each riser pipe 5, and the upper pipe opening of the riser pipe 5 is spaced apart from the liquid collecting angle steel 6, so that the riser outlets 7 are formed on both sides above the riser pipe 5. The beam frame 2 is spaced above the liquid collecting angle steel 6, so that the beam frame 2 will not hinder the rise of the gas.

[0029] In one embodiment, the lower end of at least one leveling lifting assembly 3 is connected to the riser 5. Specifically, the lower end of the leveling lifting assembly 3 extends into the gap between adjacent risers 5, and the lower end of the leveling lifting assembly 3 is connected to the outer wall of the riser 5. A lifting ring is provided at the lower end of the leveling lifting assembly 3, and a hook is provided on the outer wall of the riser 5. The hook is a U-shaped hook body, and both sides of the hook are fixed to the outer walls of the risers 5 on both sides by welding or bolting. The hook hooks the lifting ring to connect the lower end of the leveling lifting assembly 3 to the outer wall of the riser 5. The leveling lifting assembly 3 pulls the riser 5, and indirectly provides pulling force to the bottom plate 4 of the distributor 1.

[0030] In one embodiment, the lower end of at least one leveling lifting assembly 3 is connected to the bottom plate 4. Specifically, the bottom plate 4 of the distributor 1 is formed by splicing a plurality of panels, and a connecting plate is provided at the splicing of the panels. The panels are horizontal plates, and the connecting plates are vertical plates. The connecting plates are provided with transverse connecting holes, and the locking bolts pass through the connecting holes of the two connecting plates at the same time, thereby splicing the two panels together. The lower end of the leveling lifting assembly 3 is provided with a hook, which is correspondingly hooked into the connecting holes of two adjacent connecting plates, and the opening of the hook is tied with a steel wire to prevent the hook from being separated from the connecting plate.

[0031] Combined with Figure 1 , 2 As shown in FIG. 3 , the beam frame 2 includes three cross beams distributed in a triangular shape, and any two adjacent cross beams are connected and fixed by multiple connecting rods. The triangular structure of the beam frame 2 is more solid, and the gap on the beam frame 2 is large, which causes less obstruction when the gas rises, and there is basically no pressure drop when the gas passes through the beam frame 2. The cross beams and connecting rods are both hollow tubes to reduce the weight of the beam frame 2.

[0032] As attached Figure 1 As shown in the figure, two support plates 10 are arranged opposite to each other on the inner wall of the packed tower. The three beams on the beam frame 2 are divided into two bottom beams 8 and one top beam 9, and the two ends of the bottom beam 8 are fixedly overlapped on the two support plates 10, so that the beam frame 2 can be stably placed on the support plates 10. The beam frame 2 can be fixedly connected to the support plates 10 by welding.

[0033] The leveling suspension assembly 3 includes a suspension plate 11 and a suspension rod 12. The two sides of the suspension plate 11 are respectively overlapped on the two bottom cross beams 8, so that the suspension plate 11 is in a flat state. The upper end of the suspension rod 12 is connected to the suspension plate 11, and the lower end of the suspension rod 12 is connected to the distributor 1. A vertical through hole is provided on the suspension plate 11, and a threaded section is provided on the upper end of the suspension rod 12. The threaded section of the suspension rod 12 passes through the through hole and is connected to an adjusting nut 13; when the adjusting nut 13 is rotated on the threaded section of the suspension rod 12, the relative height of the suspension rod 12 and the suspension plate 11 is changed.

[0034] As attached Figure 1 and 2 As shown in , since the gas riser outlets 7 are located on both sides above the gas riser 5, the gas riser outlets 7 of two adjacent gas riser pipes 5 are opposite to each other, and when the gas flows out from the gas riser outlets 7, it is affected by the gas outlets of the opposite gas riser outlets 7, and the flow rate will decrease. Therefore, in the present invention, there is a height difference between two adjacent liquid collecting angle steels 6 on the distributor 1, so that the gas riser outlets 7 on the two adjacent gas riser pipes 5 are staggered to a certain extent. Since the gas riser outlets 7 are staggered, a part of the gas will not be affected by the gas outlets on the opposite side, thereby reducing the pressure drop of the gas after flowing out from the gas riser outlets 7.

[0035] Part of the liquid collecting angle steel 6 is movably arranged on the riser 5 and is referred to as the movable angle steel 61. Part of the liquid collecting angle steel 6 is fixedly arranged on the riser 5 and is referred to as the fixed angle steel 62. In one embodiment, the movable angle steel 61 and the fixed angle steel 62 on the distributor 1 are arranged alternately. The beam frame 2 is also provided with a differential adjustment suspension assembly 14, and the lower end of the differential adjustment suspension assembly 14 is connected to the movable angle steel 61, so that the height of the movable angle steel 61 is adjustable. Figure 4 Take the three liquid collecting angle steels 6 in the figure as an example. The higher liquid collecting angle steels 6 on both sides are fixed angle steels 62, and the lower liquid collecting angle steel 6 in the middle is a movable angle steel 61. Then, when the movable angle steel 61 is raised, the area of ​​the gas lifting outlet 7 below the movable angle steel 61 increases, which is beneficial to the flow of gas; but at the same time, the relative area of ​​the gas lifting outlet 7 below the movable angle steel 61 and the gas lifting outlet 7 below the fixed angle steel 62 will also increase, which is not conducive to the flow of gas. Therefore, in the process of raising and lowering the movable angle steel 61, both favorable and unfavorable factors will be generated for the flow of gas. Under the joint action of these two factors, it is necessary to find the optimal height of the movable angle steel 61, so that the gas lifting outlet 7 formed by the movable angle steel 61 at this height is most conducive to the flow of gas and minimizes the pressure drop of the gas through the distributor 1.

[0036] Therefore, a pressure sensor is also provided in the packed tower, and a pressure sensor is provided on the gas inlet side and the outlet side of the distributor 1. The pressure sensor can detect the pressure difference before and after the gas passes through the distributor 1, that is, the pressure drop before and after the gas passes through the distributor 1. Based on the pressure drop measured by the pressure sensor, the height of the movable angle steel 61 can be adjusted, so as to find the optimal height of the movable angle steel 61, so that the gas riser outlet 7 formed by the movable angle steel 61 at this height is most conducive to the flow of gas.

[0037] The differential adjustment suspension assembly 14 is controlled by a driving mechanism and can actively drive the movable angle steel 61 to rise and fall. Thus, the pressure drop of the gas passing through the distributor 1 can be measured when the packed tower is working normally. Multiple movable angle steels 61 can be used as an adjustment module, and the lower end of a single differential adjustment suspension assembly 14 is simultaneously connected to multiple movable angle steels 61 in a single adjustment module, so as to reduce the number of differential adjustment suspension assemblies 14 on the beam frame 2.

[0038] In addition, inside the packing tower, there will be a difference in the airflow at the inner wall of the packing tower and at the center of the packing tower, so there will be a difference in the optimal height of the movable angle steel 61 near the inner wall of the packing tower and the movable angle steel 61 near the center of the packing tower. Therefore, in actual applications, when each movable angle steel 61 is at the optimal height, the differential lifting assembly 14 will adjust the height difference between each liquid collection angle steel 6 to an unequal state, thereby minimizing the gas pressure drop measured by the air pressure sensor as much as possible.

[0039] One working method of the present invention is as follows: a support plate 10 is installed above the distributor 1 in the packed tower, and then the two ends of the assembled beam frame 2 are fixedly overlapped on the two support plates 10 respectively, and then the hanging plate 11 is overlapped on the two bottom cross beams 8 of the beam frame 2, and the lower end of the leveling hanging assembly 3 is fixedly connected to the bottom plate 4 or the riser 5 of the distributor 1, and then the height of the leveling hanging assembly 3 is adjusted by the nut, and then the bottom of the distributor 1 is adjusted to the same horizontal plane.

[0040] When the distributor 1 and the beam frame 2 are installed in the packing tower, a better height is first determined for the movable angle steel 61 according to the calculation and simulation of the computer. When the packing tower is put into use, the pressure drop of the gas before and after passing through the distributor 1 is detected by the air pressure sensor, and then the height of each movable angle steel 61 is adjusted by multiple differential suspension assemblies 14 until the pressure drop measured by the air pressure sensor is the smallest, thereby finding the best height of the movable angle steel 61. When the movable angle steel 61 is at the best height, the height of each movable angle steel 61 will also be different due to the difference in the air flow environment at the center and edge of the packing tower.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
