Description

Technical Field

[0001] This utility model relates to the field of separation tower technology, specifically to a horizontally adjustable trough-type liquid distributor. Background Technology

[0002] Liquid distributors are crucial internal components in chemical packed towers. Together with packing, liquid collectors, and packing supports, they form the separation components of the packed tower. Their core function is to ensure sufficient and uniform contact between gas and liquid, reducing the amplification effect and end effect of the packed tower caused by poor liquid distribution such as wall flow and channeling, thereby enabling the packing to achieve optimal separation performance.

[0003] The design, manufacturing, and installation level of the tower internals directly affect the separation performance and separation effect of the packing material. To ensure stable operation and uniform liquid distribution of the trough-type liquid distributor during the operation of the packed tower, the installation of the trough-type liquid distributor must strictly adhere to the levelness requirements; otherwise, the liquid level difference caused by the distributor's lack of levelness during production will severely affect the liquid distribution effect. In actual operation, on the one hand, the difference in rigidity between the middle part of the trough-type distributor and the two side troughs can lead to horizontal deviations in the liquid level, which are difficult to adjust using conventional support beam designs. More importantly, the limited installation space in small and medium-sized packed towers restricts the movement of installation workers, making the horizontal installation of the distributor extremely difficult. Therefore, there is an urgent need to find a trough-type liquid distributor with good liquid distribution effect and convenient levelness adjustment during installation.

[0004] CN110721653A discloses a multifunctional adjustable support beam, composed of components such as upright plates, stiffening plates, and support plates, installed between a trough-type liquid distributor and a packing pressure ring. In use, the distribution trough is lifted by rotating the leveling bolts, thereby adjusting the levelness of the trough-type liquid distributor on the beam.

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

[0006] To address this issue, a horizontally adjustable tank-type liquid distributor was designed to overcome the aforementioned problems. Utility Model Content

[0024] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1-2As shown, a horizontally adjustable trough-type liquid distributor includes a liquid distributor body, which consists of a distribution trough 1, a buffer trough 2, and a support beam 3. The distribution trough 1 consists of multiple parallel distributions arranged at equal intervals. Adjacent distribution troughs 1 are connected by a connecting trough 4, forming a distribution trough group. The distribution trough group is bolted to the buffer trough 2 located directly above the distribution trough group. The support beam 3 is located directly above the distribution trough group and is fixed to the support beam 3 by fasteners. The entire assembly formed by the distribution trough group and the support beam 3 is connected to a horizontal adjustment device, which adjusts the overall levelness.

[0027] The leveling device consists of a plurality of screws 5, a first nut 6, and a second nut 7. The top of each screw 5 passes through the corresponding through hole of the support beam 3 and is fixed by the first nut 6. The bottom of each screw 5 is inserted through a packing rod 8 with a connecting hole and is fixed by the second nut 7. The packing rod 8 is flush with or lower than the bottom surface of the distribution trough 1. When the liquid distributor body is installed, the overall levelness is adjusted by adjusting the height of the second nut 7.

[0028] In this invention, the support beam is connected to the packing pressure rod via a screw, enabling the support beam to fix and compact the packing. The support beams used in the distributor are generally installed in pairs, and the number of packing pressure rods is also generally paired. The number and position of the openings in the support beams used to connect to the leveling device and the stepped nuts on the packing pressure rods correspond to the number and position of the intersection points between the support beams and the packing pressure rods from a top-down view. The opening at the bottom of the packing pressure rod allows for liquid flow within the tower.

[0029] The fixing component is a fixing buckle 9, and there are multiple fixing buckles 9, which are evenly arranged above each distribution groove 1. Each fixing buckle 9 has a through hole for the bolt 19 to pass through. Corresponding connecting holes are opened on the support beam 3 and the top surface of the distribution groove 1. One end of the fixing buckle 9 is connected to the support beam 3 by the bolt 19, and the other end is fixed with a washer 10 and a spring washer 11 between it and the top surface of the distribution groove 1, and then fixed with bolt 19 to realize the connection between the support beam 3 and the distribution groove 1.

[0030] like Figure 3-4 As shown, each distribution groove 1 has openings on both sides, with sealing plates 12 installed at the openings. Liquid distribution holes 13 are provided on the side walls and lower ends of each distribution groove 1. Each liquid distribution hole 13 is equipped with a matching baffle plate 14 that surrounds it, with the bottom of the baffle plate 14 being lower than the height of the liquid distribution hole 13.

[0031] In this invention, the length of the baffle plate matches the distribution groove, the width of the baffle plate is 50-120mm, and the upper end of the baffle plate is bent towards the side wall of the distribution groove at a bending angle of 120-175°. The lower end of the baffle plate is lower than the height of the liquid distribution hole on the side wall.

[0032] The size of the distribution tank is determined according to the designed gas flow rate. Liquid distribution holes are provided on the side wall and lower end of the distribution tank. The position of the liquid distribution holes is 20-80mm above the bottom of the tank, and the diameter of the liquid distribution holes is 2-10mm, which is determined by the designed liquid flow rate.

[0033] A first supporting angle steel 15 is provided between two adjacent distribution grooves 1 to improve the overall strength after installation.

[0034] The support beam 3 has multiple mounting holes 20, and a distributor lug 16 is installed in each mounting hole 20.

[0035] The bottom of the buffer tank 2 has a liquid outlet hole 17 for communicating with the distribution tank 1 group, and a second supporting angle steel 18 is provided in the buffer tank 2 to improve the overall strength.

[0036] The liquid baffle 14 consists of at least two baffles distributed on both sides of the bottom of the distribution trough 1 in a figure-eight arrangement.

[0037] The upper part of the distribution groove 1 is a cuboid groove, and its bottom is a flat bottom or a conical bottom.

[0038] The width of the connecting groove 4 is greater than the width of the buffer groove 2. An angle steel is welded inside the connecting groove 4, with a hole in the center of the angle steel, and a stepped nut is welded at the hole position.

[0039] The design features of this utility model are as follows:

[0040] 1. During the installation of the distributor, the distributor trough is fixed and hoisted onto the support beam with bolts. If the distributor tilts, the level of the trough liquid distributor can be quickly adjusted by adjusting the position of the second nut on the leveling device, thereby ensuring the high level of the distributor to the maximum extent and reducing the standard deviation of the liquid level in the distributor to within 10% when starting up. The distributor can then perform its liquid distribution function normally, improving the overall efficiency of the packed tower.

[0041] 2. The packing pressure rod is connected to the distributor and support beam by bolts, which can tighten the packing and prevent the packing from being loosened by the rising airflow. This allows the packing to fully perform its function and saves the cost of making a separate packing pressure ring.

[0042] 3. When the packed tower is started, the liquid phase inside the tower is sprayed into the buffer tank, and then flows to each distribution tank for liquid phase distribution. The liquid is evenly sprayed onto the packing through the distribution holes and will not overflow from the top of the distribution tank.

[0043] 4. The distributor horizontal adjustment device of this utility model has a simple structure, strong horizontal adjustment capability, strong rigidity, and is easy to operate without affecting the normal operation of the distributor.

[0044] The working process of this utility model is as follows:

[0045] During the installation of the distributor, installers fix the distribution trough to the support beam with bolts to form a whole. The lower ends of multiple adjusting screws are connected to the horizontally placed packing pressure rods, and the upper ends are connected to the whole formed by the support beam and the distribution trough. At this time, the second nut on the adjusting screw connected to the lower part of the support beam can play a limiting role. 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 adjust the overall level of the trough liquid distributor. This maximizes the high levelness requirement of the distributor, so that the standard deviation of the liquid level in the distributor is reduced to less than 10% when starting up. The distributor can perform its liquid distribution performance normally and improve the overall efficiency of the packed tower.

[0046] The packing pressure bar is connected to the distribution groove and support beam as a whole through the adjusting screw. It can use the weight of the distributor to compress the packing, avoiding the packing from being loosened by the rising airflow. This allows the packing to fully perform its function and saves the cost of making a separate packing pressure ring.

[0047] When the packed tower is started, the liquid phase inside the tower is sprayed onto the buffer tank, thereby reducing the overall impact intensity of the liquid and playing a buffering role. The liquid phase in the buffer tank flows to each distribution tank through the liquid outlet at the bottom. The tanks are interconnected, which can keep all tanks at the same level liquid surface, making it 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.

[0048] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
