Description

Technical Field

[0001] The present invention relates to the technical field of separation towers, and particularly relates to a horizontally adjustable trough-type liquid distributor. Background Art

[0002] A liquid distributor is a crucial internal component in a chemical packing tower. It, together with packing, a liquid collector, a packing support, etc., constitutes the separation internal components of the packing tower. Its core function is to enable sufficient and uniform contact between gas and liquid, reduce the amplification effect and end effect of the packing tower caused by poor liquid distribution such as wall flow and channel flow, so as to enable the packing to achieve the best separation performance.

[0003] The level of design, manufacturing, and installation of the internal components of the tower directly affects the performance of the packing separation and the realization of the separation effect. To ensure stable operation of the trough-type distributor and uniform liquid distribution during the operation of the packing tower, strict requirements are imposed on the levelness of the trough-type liquid distributor during installation. Otherwise, the liquid level difference caused by the non-levelness of the distributor during production will seriously affect the liquid distribution effect. In actual operation, on the one hand, due to the different rigidities of the middle part and the two-side troughs of the trough-type distributor, a horizontal deviation of the liquid level will occur, which is difficult to adjust through the design of a conventional support beam. More importantly, the installation space of medium and small-sized packing towers is narrow, and the activities of installation workers are restricted, which brings great difficulties to the horizontal installation of the distributor. Therefore, there is an urgent need to find a trough-type liquid distributor with good liquid distribution effect and convenient adjustment of levelness during installation.

[0004] CN110721653A discloses a multifunctional adjustable support beam, which is composed of components such as vertical plates, rib plates, and support plates, and is installed in the middle of the trough-type liquid distributor and the packing retainer ring. During use, the distribution trough is lifted by rotating the leveling bolt to adjust the levelness of the trough-type liquid distributor on the beam.

[0005] The support beam disclosed in the above patent is mainly used for large-scale packing towers. Its structure is relatively complex, and it will make the work more cumbersome when applied to medium and small-sized packing towers. Moreover, this structure lifts the distributor to level it, which is ineffective for leveling the hoisted distributor.

[0006] Therefore, a horizontally adjustable trough-type liquid distributor is designed to overcome the above problems. Summary of the Invention

[0020] To enable those of ordinary skill in the art to more clearly understand the purpose, technical solution and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal", "vertical", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or component referred to must have a specific orientation, and thus should not be construed as a limitation to the present invention.

[0022] The present invention will be described in detail below with reference to the drawings: As Figure 1-2As shown in the figure, a horizontally adjustable trough-type liquid distributor includes a liquid distributor body, which is composed of a distribution trough 1, a buffer trough 2, and a support beam 3. The distribution troughs 1 are arranged in parallel at equal intervals with each other. Adjacent two distribution troughs 1 are connected by a communication trough 4, so that a distribution trough group is formed among the multiple distribution troughs 1. The distribution trough group is connected to the buffer trough 2 arranged directly above the distribution trough group by bolts. And a support beam 3 is arranged directly above the distribution trough group. The distribution trough group and the support beam 3 are fixed by a fixing member. And the whole formed between the distribution trough group and the support beam 3 is connected to a horizontal adjusting device, and the levelness of the whole is adjusted by the horizontal adjusting device.

[0023] The horizontal adjusting device is composed of a plurality of screw rods 5, a first nut 6, and a second nut 7. The top of each screw rod 5 passes through the through hole corresponding to the support beam 3 and is fixed by the first nut 6. Its bottom penetrates and inserts into a stuffing press rod 8 with a connection hole and is fixed by the second nut 7. The stuffing press rod 8 is flush with or lower than the bottom surface of the distribution trough 1. When the liquid distributor body is installed, by adjusting the height position of the second nut 7, the function of adjusting the overall levelness is achieved.

[0024] In the present invention, the support beam is connected to the stuffing press rod through a screw rod, so that the support beam plays a role in fixing and compacting the stuffing. The support beams used in the distributor are generally arranged in pairs, and the number of stuffing press rods is generally arranged in pairs. The number and position of the openings of the support beam for connecting the horizontal adjusting device and the step nuts of the stuffing press rod correspond to the number and position of the intersection points of the support beam and the stuffing press rod from the top view. The bottom end of the stuffing press rod is provided with an opening for the liquid in the tower to flow through.

[0025] The fixing member is a fixing buckle 9. There are a plurality of fixing buckles 9, which are respectively and evenly arranged directly above each distribution trough 1. Each fixing buckle 9 is provided with a through hole for a bolt 19 to pass through. Connection holes corresponding to the through holes are respectively opened on the support beam 3 and the top surface of the distribution trough 1. One end of the fixing buckle 9 is connected to the support beam 3 by a bolt 19. After a washer 10 and a spring washer 11 are arranged between the other end and the top surface of the distribution trough 1, it is fixed by a bolt 19 again, realizing the connection between the support beam 3 and the distribution trough 1.

[0026] As Figure 3-4 shown, openings are arranged on both sides of each distribution trough 1. A sealing plate 12 is installed at the opening. And liquid distribution holes 13 are arranged on the side wall and the lower end of each distribution trough 1. Liquid baffle plates 14 that match and surround the liquid distribution holes 13 are arranged at the liquid distribution holes 13. The bottom height of the liquid baffle plate 14 is lower than the height of the liquid distribution holes 13. The length of the liquid baffle in the present invention matches the distribution groove. The width of the liquid baffle is 50 - 120 mm, and the upper end of the liquid baffle is bent towards the side wall of the distribution groove, with a bending angle of 120 - 175°. The position of the lower end of the liquid baffle is lower than the height position of the liquid distribution holes on the side wall.

[0027] The size of the distribution groove is determined according to the designed gas flux. Liquid distribution holes are provided on the side wall and the lower end of the distribution groove. The height of the liquid distribution holes from the bottom of the groove is 20 - 80 mm, and the diameter range of the liquid distribution holes is 2 - 10 mm, which is determined by the designed liquid phase flow rate.

[0028] A first support angle steel 15 is arranged between two adjacent distribution grooves 1 to improve the overall strength after installation.

[0029] A plurality of mounting holes 20 are formed on the support beam 3, and a distributor lifting lug 16 is installed in each mounting hole 20.

[0030] A liquid outlet hole 17 is formed at the bottom of the buffer groove 2 for communicating with the distribution groove 1 group, and a second support angle steel 18 is arranged in the buffer groove 2 to improve the overall strength.

[0031] At least two liquid baffles 14 are distributed on both sides of the bottom of the distribution groove 1, arranged in a V-shaped layout.

[0032] The upper part of the distribution groove 1 is a cuboid groove, and its bottom is a flat bottom or a conical bottom.

[0033] The width of the communication groove 4 is greater than the width of the buffer groove 2. Angle steel is welded inside the communication groove 4, with a hole in the center of the angle steel, and a step nut is welded at the hole position.

[0034] The design features of the present invention are as follows: 1. When installing the distributor, the distributor groove is fixedly hoisted on the support beam through bolts. When the distributor is inclined, the levelness of the trough - type liquid distributor can be quickly adjusted by adjusting the position of the second nut on the horizontal adjustment device, so as to ensure the high - levelness requirement of the distributor to the greatest extent, and reduce the standard deviation value of the liquid level in the distributor to within 10% during startup; the distributor can normally exert its liquid distribution performance and improve the overall efficiency of the packed tower.

[0035] 2. The packing pressure bar is integrally connected to the distributor and the support beam through bolts, which can compress the packing, avoid the loosening of the packing caused by the upward airflow, enable the packing to fully exert its performance, and save the cost of separately manufacturing the packing retaining ring.

[0036] 3. When the packed tower is in operation, the liquid phase in the tower is sprayed onto the buffer groove, and then flows to each distribution groove for liquid phase distribution. The liquid is evenly sprayed on the packing through the distribution holes and will not overflow from the upper end of the distribution groove.

[0037] 4. The distributor horizontal adjustment device of the present invention has a simple structure, strong horizontal adjustment ability, strong rigidity, convenient operation and does not affect the normal operation of the distributor.

[0038] The working process of the present invention is as follows: When installing the distributor, the installer fixes the distribution tank on the support beam through bolts to form an integral body; the lower ends of a plurality of adjusting screws are connected to the horizontally placed packing pressing rod, and the upper ends are connected to the integral body formed by the connection of the support beam and the distribution tank. At this time, the second nut connected to the lower part of the support beam on the adjusting screw can play a limiting role, and the installer can quickly change the height of any end of the support beam by adjusting the position of the second nut, so as to achieve the effect of adjusting the levelness of the overall trough-type liquid distributor, thereby ensuring the high-levelness requirement of the distributor to the greatest extent, reducing the standard deviation value of the liquid level in the distributor to within 10% during startup, enabling the distributor to normally exert its liquid distribution performance, and improving the overall efficiency of the packed tower.

[0039] The packing pressing rod is connected to the distribution tank and the overall support beam through the adjusting screw, and can use the weight of the distributor to press the packing, avoiding the loosening of the packing caused by the upward airflow, enabling the packing to fully exert its performance, and saving the cost of separately manufacturing the packing retaining ring.

[0040] When the packed tower is started up, the liquid phase in the tower will be sprayed on the buffer tank, thereby reducing the overall impact strength of the liquid and playing a buffering role. The liquid phase in the buffer tank flows to each distribution tank through the liquid outlet holes at the bottom. The tanks are interconnected with each other, and all the tanks can maintain the same horizontal liquid level, which is easy to achieve uniform liquid phase distribution. Subsequently, the liquid phase is evenly sprayed onto the packing below through the distribution holes at the bottom of the distribution tank, making the liquid distribution in the tower more uniform and improving the overall efficiency of the packed tower.
