Description

Technical Field

[0001] This utility model relates to the field of tower tray technology, and in particular to an energy-saving and high-efficiency spray tower tray. Background Technology

[0002] Sieve trays are a classic gas-liquid mass transfer device, widely used in chemical unit operations such as distillation and absorption. Their structure mainly consists of trays with numerous sieve openings. Liquid flows down from the upper tray through downcomers, forming a liquid layer on the tray, while gas flows upward through the sieve openings, achieving full contact with the liquid to realize mass and heat transfer. Sieve trays have advantages such as simple structure, low cost, moderate pressure drop, and ease of maintenance, making them suitable for the separation of clean systems or low-viscosity liquids.

[0003] However, sieve trays also have certain limitations. The sieve apertures on existing sieve trays are very small, making them prone to clogging, especially when processing materials containing solids. This leads to increased pressure drop within the tray and consequently higher energy consumption. Furthermore, while small apertures cause clogging and high pressure drop, excessively large apertures can lead to droplet entrainment. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an energy-saving and high-efficiency spray tower tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving and high-efficiency spraying tower tray, comprising a lower tower plate and an upper tower plate, wherein the lower tower plate has a plurality of lower sieve holes, and the upper tower plate has a plurality of upper sieve holes corresponding to the lower sieve holes. A funnel is fixed between the lower sieve holes and the corresponding upper sieve holes. A vertical shaft is rotatably connected to the lower tower plate and the upper tower plate through the middle of the two tower plates and via a bearing. An extrusion assembly is fixed to the bottom and top surfaces of the vertical shaft. The extrusion assembly includes an end plate and a sliding sleeve. A cleaning assembly is fixed to the outer walls of the two sliding sleeves. The two cleaning assemblies are respectively located on the lower surface of the lower tower plate and the upper surface of the upper tower plate. L-shaped support rods are fixed to both sides of the upper surface of the upper tower plate. An outer shell is fixed to the adjacent ends of the two support rods. A motor for driving the vertical shaft to rotate is installed inside the outer shell.

[0006] Furthermore, mounting plates are fixed on both sides of the lower tower plate, and mounting holes are provided on the mounting plates.

[0007] Furthermore, the diameter of the lower sieve hole is smaller than the diameter of the upper sieve hole.

[0008] Furthermore, the end plate is fixed to the surface of the vertical shaft, and a spring is fixed to the side of the end plate near the lower or upper tower plate. A sliding plate is fixed to the other end of the spring, and the sliding plate is fixedly connected to the sliding sleeve. Both the sliding plate and the sliding sleeve are slidably sleeved on the surface of the vertical shaft.

[0009] Furthermore, an insert rod is fixed to the outer wall of the sliding sleeve, and the cleaning component includes a brush. A groove for inserting the insert rod is provided at one end of the brush near the sliding sleeve. A fastening bolt is threadedly connected to the side wall of the groove and rotated through it. One end of the fastening bolt located in the groove is in contact with the surface of the insert rod.

[0010] Furthermore, the top end of the vertical shaft passes through the bottom wall of the housing and is rotatably connected to the housing via a bearing, and the top end of the vertical shaft is fixedly connected to the bottom output end of the motor.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model is an energy-saving and high-efficiency spray tower tray, which is equipped with a lower tower plate, an upper tower plate and a mounting plate. The lower sieve hole of the lower tower plate and the upper sieve hole of the upper tower plate are fixedly connected to the funnel bucket, so that the sieve hole gradually enlarges from bottom to top. The airflow flows upward and first passes through the lower sieve hole with a smaller diameter and then through the upper sieve hole. This can reduce the gas phase pressure drop inside the tower and improve the gas-liquid contact efficiency, thereby reducing the energy consumption of the sieve plate tower.

[0013] 2. In use, this utility model is an energy-saving and high-efficiency spray tray, which is equipped with two sets of cleaning components, a vertical shaft, two sets of extrusion components and a motor. The motor drives the vertical shaft to rotate, and the vertical shaft in turn drives the two sets of extrusion components to rotate. The extrusion components on the surface of the vertical shaft drive the two sets of cleaning components to rotate on the surfaces of the lower and upper trays respectively. The cleaning components clean the lower and upper sieve holes, preventing the lower and upper sieve holes from becoming clogged, further preventing the pressure drop from increasing, and achieving the purpose of reducing energy consumption.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, an energy-saving and high-efficiency spraying tower tray is disclosed, comprising a lower tower plate 1 and an upper tower plate 2. The lower tower plate 1 has several lower sieve holes 101, and the upper tower plate 2 has several upper sieve holes 201 corresponding to the lower sieve holes 101. A funnel hopper 3 is fixed between the lower sieve holes 101 and the corresponding upper sieve holes 201. A vertical shaft 6 is rotatably connected to the lower tower plate 1 and the upper tower plate 2 through the middle of the two tower plates and via a bearing. An extrusion assembly 7 is fixed to the bottom and top surfaces of the vertical shaft 6. The extrusion assembly 7 includes an end plate 71 and a sliding sleeve 74. A cleaning assembly 5 is fixed to the outer wall of each of the two sliding sleeves 74. The two cleaning assemblies 5 are located on the lower surface of the lower tower plate 1 and the upper surface of the upper tower plate 2, respectively. L-shaped support rods 8 are fixed to both sides of the upper surface of the upper tower plate 2. An outer shell 9 is fixed to the adjacent ends of the two support rods 8. A motor 10 for driving the vertical shaft 6 to rotate is installed inside the outer shell 9.

[0023] Mounting plates 4 are fixed on both sides of the lower tower plate 1, and mounting holes are provided on the mounting plates 4.

[0024] In this embodiment, the mounting holes on the mounting plate 4 match the holes on the inner wall of the tower body. The mounting plate 4 can be fixed to the inner wall of the tower body by bolts, thereby fixing the lower tower plate 1 and realizing the overall installation of the tower tray.

[0025] The diameter of the lower sieve hole 101 is smaller than the diameter of the upper sieve hole 201.

[0026] When the airflow flows from bottom to top, it first passes through the lower sieve hole 101 and then through the upper sieve hole 201 along the funnel 3, which can reduce the gas phase pressure drop inside the tower.

[0027] The end plate 71 is fixed to the surface of the vertical shaft 6, and a spring 72 is fixed to the side of the end plate 71 near the lower tower plate 1 or the upper tower plate 2. The other end of the spring 72 is fixed to a sliding plate 73, and the sliding plate 73 is fixedly connected to the sliding sleeve 74. Both the sliding plate 73 and the sliding sleeve 74 are slidably sleeved on the surface of the vertical shaft 6.

[0028] Since the cleaning component 5 is fixed on the surface of the sliding sleeve 74, the cleaning component 5 on the surface of the sliding sleeve 74 can be moved to the side of the lower tray 1 or the upper tray 2 by the spring 72 squeezing the slide plate 73 and the sliding sleeve 74, so as to ensure that the cleaning component 5 can fit with the lower tray 1 or the upper tray 2, thereby ensuring that the lower sieve hole 101 and the upper sieve hole 201 can be cleaned.

[0029] A rod 75 is fixed to the outer wall of the sliding sleeve 74. The cleaning component 5 includes a brush 51. A groove 52 for inserting the rod 75 is provided at one end of the brush 51 near the sliding sleeve 74. A fastening bolt 53 is connected through the side wall of the groove 52 by a threaded rotation. One end of the fastening bolt 53 located in the groove 52 is in contact with the surface of the rod 75.

[0030] When installing the brush 51, the groove 52 of the brush 51 is fitted onto the surface of the insert rod 75, and then the surface of the insert rod 75 is pressed by tightening the fastening bolt 53, thus fixing the brush 51 in place. This also allows the brush 51 to be disassembled for easy replacement.

[0031] The top end of the vertical shaft 6 passes through the bottom wall of the outer casing 9 and is rotatably connected to the outer casing 9 via a bearing. The top end of the vertical shaft 6 is fixedly connected to the bottom output end of the motor 10.

[0032] In this embodiment, the vertical shaft 6 and the outer casing 9 are connected by a sealed rotation. When the power line and control line of the motor 10 pass through the outer casing 9, they are also connected to the outer casing 9 in a sealed manner, thereby ensuring that the interior of the outer casing 9 is sealed and protecting the motor 10. The motor 10 interface is started to drive the vertical shaft 6 to rotate.

[0033] Working principle: During installation, the tower tray is fixed in place by the mounting plate 4. During use, as the airflow inside the tower flows upward, it first passes through the lower sieve hole 101 and then through the upper sieve hole 201. When the pressure drop inside the tower increases, the motor 10 is started to drive the vertical shaft 6 to rotate, which in turn drives the brush 51 fixed on the surface of the sliding sleeve 74 to rotate. The two brushes 51 clean the lower sieve hole 101 and the upper sieve hole 201 respectively, preventing blockage of the lower sieve hole 101 and the upper sieve hole 201, further preventing the pressure drop from increasing, and thus achieving the purpose of reducing energy consumption.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
