Description

Technical Field

[0001] This utility model relates to the field of benzene washing tower packing technology, specifically a benzene washing tower packing device. Background Technology

[0002] A benzene washing tower is a washing device used in the crude benzene absorption process. The tower is equipped with a spray device, a packing device, and a liquid distribution device. The wash oil is evenly distributed on the surface of the packing through the spray device at the top of the tower and comes into countercurrent contact with the coal gas entering from the bottom of the tower. The oil rich in crude benzene absorbed from the coal gas is discharged from the bottom of the tower. The purpose of the packing installed in the benzene washing tower is to reduce the flow rate of the coal gas entering the benzene washing tower and to distribute the coal gas evenly, so that it rises slowly and comes into contact with the absorbent oil sprayed by the absorbent liquid spray pipe system located at the top of the benzene washing tower, thereby purifying the benzene carried in the coal gas.

[0003] Currently, some benzene washing tower packing devices on the market use a honeycomb structure. The vertical through holes cause the oil to fall quickly, resulting in a short contact time between the washing oil and the countercurrent gas, which leads to an unsatisfactory absorption effect of benzene-like substances in the gas.

[0004] Therefore, we propose a benzene washing tower packing device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problem that some existing benzene washing tower packing devices use a honeycomb structure and vertical through holes, which leads to a faster oil drop speed and a shorter contact time between the washing oil and the countercurrent gas, resulting in an unsatisfactory absorption effect of benzene compounds in the gas.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a benzene washing tower packing device, characterized in that it includes: a device frame, the device frame being provided with a plurality of packing assemblies, the packing assembly including a packing frame, a packing plate being provided inside the packing frame, the packing plate being configured with a corrugated structure and the packing plate being inclinedly arranged inside the packing frame, an oil outlet being opened at the lower end of the packing plate, a plurality of corrugated grooves being provided on the packing plate, and a plurality of oil dripping holes being opened in the corrugated grooves, the packing plates of adjacent packing assemblies having opposite inclination angles; The device frame is provided with an upper encapsulation frame at the top and a lower encapsulation frame at the bottom, thereby confining multiple filler components within the device frame.

[0007] Furthermore, the upper encapsulation frame includes an upper frame body, on which a first grid plate is disposed, and a first buffer mesh is disposed at each slot position of the first grid plate; the lower encapsulation frame includes a lower frame body, on which a second grid plate is disposed, and a second buffer mesh is disposed at each slot position of the second grid plate.

[0008] Furthermore, the upper encapsulation frame is provided with lifting ears.

[0009] Furthermore, the upper encapsulation frame is provided with a mounting ring, and multiple connecting bolts are arranged around the mounting ring.

[0010] Furthermore, the outer surface of the filler frame is provided with a plurality of limiting sliders, and the inner surface of the device frame is provided with a plurality of limiting grooves, wherein the limiting sliders are slidably connected to the limiting grooves.

[0011] Furthermore, the corrugated grooves of each of the packing plates are arranged laterally.

[0012] The beneficial effects of this utility model are as follows: By setting multiple packing assemblies in the device frame, and setting corrugated packing plates in the packing frames of the packing assemblies, with the packing plates of adjacent packing assemblies tilted at opposite angles, and setting multiple corrugated grooves on the packing plates, the inclined corrugated packing plates greatly extend the path length of the wash oil flowing downward along the packing plates, thereby increasing the gas-liquid contact time and making the absorption of benzene substances more complete. The opposite tilt angle of the packing plates of two adjacent packing assemblies forces the rising coal gas to change its flow direction when passing through two layers of packing plates, forming a zigzag flow path, which forms cross-convection with the wash oil on the surface of the packing plates tilted in the opposite direction, thereby improving the absorption effect of benzene substances in the coal gas.

[0015] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] Embodiments of this utility model: like Figures 1-5 As shown, this utility model provides a benzene washing tower packing device, including a device frame 1. The device frame 1 is provided with multiple packing assemblies 2, each packing assembly 2 including a packing frame 21. A packing plate 22 is disposed within the packing frame 21. The packing plate 22 has a corrugated structure and is inclinedly disposed within the packing frame 21. An oil outlet 23 is provided at the lower end of the packing plate 22. Multiple corrugated grooves 24 are provided on the packing plate 22, with each corrugated groove 24 being horizontally arranged. The corrugated structure increases the effective mass transfer area of ​​the packing plate 22, and the horizontal corrugated grooves 24 can "catch" the contents. The washing oil is prevented from flowing away quickly, and multiple drip holes 25 are opened in the corrugated groove 24. The packing plates 22 of adjacent packing assemblies 2 are tilted at opposite angles. The tilting of the packing plates 22 is matched with the opposite angle of the packing plates 22 of adjacent packing assemblies 2, which extends the flow path of the washing oil and forces the rising gas to change its flow direction, forming gas-liquid turbulence, which can enhance the absorption of benzene-like substances. The transverse corrugated groove 24 allows the washing oil to diffuse laterally along the corrugated groove 24, avoiding the phenomenon of "channeling" where the washing oil concentrates in a localized area and flows down quickly. The drip holes 25 can prevent washing oil residue on the one hand, and on the other hand, the falling oil droplets increase the contact area between the washing oil and the gas, thus improving the absorption effect.

[0017] like Figures 1-5 As shown, an upper encapsulation frame 3 is provided at the top of the device frame 1, and a lower encapsulation frame 4 is provided at the bottom of the device frame 1. The upper and lower encapsulation frames 3 and 4 confine multiple filler components 2 within the device frame 1. The upper encapsulation frame 3 includes an upper frame body 31, on which a first mesh plate 32 is provided. A first buffer mesh 33 is provided at each slot position of the first mesh plate 32. A first slot adapted to the device frame 1 is opened on the lower surface of the upper frame body 31. The lower encapsulation frame 4 includes a lower frame body 41, on which a first buffer mesh 33 is provided. The second grid plate 42 has a second buffer net 43 in each of its slots.

The upper frame 31 and the lower frame 41 are connected and fixed to the device frame 1 by countersunk bolts 9. With this configuration, the upper encapsulation frame 3 and the lower encapsulation frame 4 can be disassembled as needed to remove the filling component 2 inside the device frame 1 for cleaning and replacement.

[0018] like Figures 1-5 As shown, the upper encapsulation frame 3 is provided with lifting lugs 5, which can be used to lift the device into the benzene washing tower by external lifting equipment. The upper encapsulation frame 3 is provided with an installation ring 6, and multiple connecting bolts 7 are arranged around the installation ring 6 to facilitate the installation and fixation of the device to the inner wall of the benzene washing tower.

[0019] like Figures 1-5 As shown, the outer surface of the filler frame 21 is provided with multiple limiting sliders 8, and the inner surface of the device frame 1 is provided with multiple limiting grooves 101. The limiting sliders 8 are slidably connected to the limiting grooves 101 to prevent displacement.
