Description

Technical Field

[0001] The invention relates to the technical field of packed tower internals, in particular to a distributor. Background Art

[0002] As a mass transfer equipment with the filler in the tower as the contact structure between the gas and liquid phases, the packed tower is widely used in the fields of oil refining, chemical industry, fertilizer, etc. The tower body of the packed tower is a vertical cylinder, and its internal parts include a liquid distributor, filler, filler support grid, etc. Among them, the liquid distributor is installed in the tower and is used to distribute the liquid introduced through the liquid collector or feed pipe across the horizontal cross-section of the tower in a defined manner and transport the liquid downward. Specifically, the liquid distributor is used to evenly distribute the liquid phase, so the use of the liquid distributor plays a very important role in ensuring the distillation efficiency of the filler.

[0003] At present, liquid distributors are generally divided into tubular distributors and trough distributors. For trough distributors, the distributor usually includes a main trough and a sub-trough. The main channel guides the liquid to the corresponding sub-trough, and the liquid is distributed downward from the main trough and the sub-trough through the opening at the bottom of the trough. At present, most of the trough distributors on the market are made of stainless steel. However, when the packed tower is used to process halogen, strong acid, strong alkali and other media, the stainless steel material needs to be replaced during the maintenance cycle due to corrosion, or it will fail before the maintenance cycle when the corrosion rate is high, which brings a lot of trouble to the on-site operation. For the more corrosion-resistant Zr (zirconium) distributor, its raw materials are expensive. Therefore, in the long run, it is difficult to solve the problem of the scarcity of raw materials themselves, so it has no economic value. Similarly, the same is true for Ti (titanium) and titanium alloys. And in terms of corrosion resistance, precious metals still have limitations. In addition, in special distillation occasions where metal ions need to be controlled, such as the production process of electronic-grade chemicals, precious metals cannot be used. Other materials, such as PTFE, are also used in industry, but because they are plastic materials, they have poor high temperature resistance and are easy to deform, so the diameter should not be made very large. In addition, due to the high processing difficulty of existing precious metals and plastic PTFE materials, the drop point density of the liquid distributor generally cannot meet the requirements of efficient distillation (such as 200 drop points / m2), which also brings limitations to the use of liquid distributors.

[0004] As described above, the prior art uses carbon fiber materials to make distributors, but for the distributors made of carbon fiber materials in the prior art, the frame used to enclose the main trough and the sub-trough is generally an integrated structure, the manufacturing process of the frame is relatively cumbersome, and it is difficult to assemble it into the tower.

[0005] Therefore, the above problems need to be solved urgently. Summary of the invention

[0042] See also Figures 1 to 11 The present embodiment provides a distributor made of carbon fiber material, the distributor comprising a bottom plate 1 and a surrounding frame 2, wherein the bottom plate 1 is provided with a first gas phase channel and a second gas phase channel on both sides along a first direction, the first gas phase channel divides one side of the bottom plate 1 along the first direction into at least two first plate portions 13, the second gas phase channel divides the other side of the bottom plate 1 along the first direction into at least two second plate portions 14, the at least two first plate portions 13 and the at least two second plate portions 14 are arranged along the second direction, the first direction is perpendicular to the second direction, the first plate portion 13, the second plate portion 14 and the portion of the bottom plate 1 between the first plate portion 13 and the second plate portion 14 are provided with The bottom plate 1 has a through hole 15, and the surrounding frame 2 is fixedly connected to the bottom plate 1 and includes a side plate 21 and an end plate 22. The bottom plate 1 is provided with side plates 21 on both sides along the second direction, on one side of all first plate portions 13 adjacent to the first gas phase channel, and on one side of all second plate portions 14 adjacent to the second gas phase channel. Along the second direction, any two adjacent side plates 21 are fixedly connected with an end plate 22. All side plates 21 are connected end to end through the end plates 22 to form the surrounding frame 2. The end plates 22 are inserted and sealed at the ends of two adjacent side plates 21 along the first direction. The surrounding frame 2 and the bottom plate 1 are constructed to form a liquid separation tank. The liquid separation tank and the first gas phase channel as well as the liquid separation tank and the second gas phase channel are separated by the end plates 22.

[0043] Based on the above, the two side plates 21 arranged on the first plate portion 13 and the end plate 22 located between the two side plates 21 jointly form a first sub-groove 271, the two side plates 21 arranged on the second plate portion 14 and the end plate 22 located between the two side plates 21 jointly form a second sub-groove 272, and in addition, the main groove 273 is formed between the first plate portion 13 and the second plate portion 14, and the main groove 273, the first sub-groove 271 and the second sub-groove 272 together constitute a liquid separation groove.

[0044] Specifically, the first gas phase channel and the second gas phase channel are both hole-shaped structures, with the side plate 21 disposed on the side of the first plate portion 13 adjacent to the first gas phase channel being the first side plate 211, the side plate 21 disposed on the side of the second plate portion 14 adjacent to the second gas phase channel being the second side plate 212, the side plate 21 disposed on one side of the bottom plate 1 along the second direction being the third side plate 213, the side plate 21 disposed on the other side of the bottom plate 1 along the second direction being the fourth side plate 214, and the first gas phase channel connects the bottom plate 1 along the second direction. The first side of the bottom plate 1 along the first direction is divided into 13 first plate portions 13, and the second gas phase channel divides the other side of the bottom plate 1 along the first direction into 13 second plate portions 14. Specifically, the first gas phase channel includes 12 first partition holes 111, and the 12 first partition holes 111 are arranged at intervals along the second direction, so as to divide the side of the bottom plate 1 along the first direction into 13 first plate portions 13. For any first plate portion 13, a second gas phase channel is arranged between the two first side plates 211 arranged thereon. An end plate 221 is provided. For the third side plate 213 and the fourth side plate 214, a first end plate 221 is also provided between the third side plate 213 and the first side plate 211 adjacent thereto, and a first end plate 221 is also provided between the fourth side plate 214 and the first side plate 211 adjacent thereto. The first end plate 221 is located on the side of the first plate portion 13 away from the second plate portion 14. In addition, a second end plate 222 is provided corresponding to all the first partition holes 111. The second end plate 222 is located on the side of the first partition hole 111. 11 is close to the side of the second partition hole 121. It can be understood that the second end plate 222 is inserted and blocked between the two first side plates 211 respectively located on both sides of the first partition hole 111, so that the third side plate 213, all the first side plates 211 and the fourth side plate 214 are connected end to end, wherein the first end plate 221 and the two first side plates 211 respectively located on both sides thereof jointly form a first sub-groove 271, thereby forming 13 first sub-grooves 271 on one side of the bottom plate 1 along the first direction.

[0045] In addition, the second gas phase channel includes 12 second partition holes 121, and the 12 second partition holes 121 are arranged at intervals along the second direction, so as to divide the other side of the bottom plate 1 along the first direction into 13 second plate portions 14. For any second plate portion 14, a third end plate 223 is arranged between the two second side plates 212 arranged thereon. For the third side plate 213 and the fourth side plate 214, a third end plate 223 is also arranged between the third side plate 213 and the second side plate 212 adjacent thereto, and a third end plate 223 is also arranged between the fourth side plate 214 and the second side plate 212 adjacent thereto. The third end plate 223 is located at the second plate portion 14. A side away from the first plate portion 13, in addition, all the second partition holes 121 are correspondingly provided with a fourth end plate 224, and the fourth end plate 224 is located on the side of the second partition hole 121 close to the first partition hole 111. It can be understood that the fourth end plate 224 is inserted and blocked between the two second side plates 212 respectively located on both sides of the second partition hole 121, thereby connecting the third side plate 213, all the second side plates 212 and the fourth side plate 214 end to end, wherein the third end plate 223 and the two second side plates 212 respectively located on both sides thereof jointly form a second sub-groove 272, thereby forming 13 second sub-grooves 272 on the other side of the bottom plate 1 along the first direction.

[0046] From above, the main groove 273 is formed between the 13 first sub-grooves 271 and the 13 second sub-grooves 272, and the 13 first sub-grooves 271 and the 13 second sub-grooves 272 are all connected to the main groove 273. The main groove 273 can guide the liquid into the first sub-grooves 271 and the second sub-grooves 272. Moreover, based on the above, the liquid can be distributed downward through the perforations 15 arranged at the bottom of the main groove 273, the perforations 15 arranged at the bottom of the first sub-grooves 271, and the perforations 15 arranged at the bottom of the second sub-grooves 272, so that the liquid can drip into the top of the filler located below the distributor.

[0047] Based on the contents mentioned above, in the present embodiment, the frame 2 for enclosing and forming the main slot 273, the first sub-slot 271 and the second sub-slot 272 is formed by a plurality of side panels 21 and end panels 22. The process of manufacturing a single side panel 21 and an end panel 22 is relatively simple. Moreover, the present embodiment can reduce the difficulty of assembling the distributor into the tower by transporting the side panels 21 and the end panels 22 one by one into the packed tower and assembling them in the tower.

[0048] Furthermore, it should be noted that the slot widths of all first sub-slots 271 and all second sub-slots 272 along the second direction are the same. Specifically, the slot width is greater than the minimum required slot width calculated based on the liquid distribution quality that needs to be met. Specifically, the maximum flow rate of the sub-slot corresponding to the liquid distribution quality is first found, and then the minimum required slot width is calculated based on the liquid flow rate allocated to each sub-slot.

[0049] In addition, it should be noted that, for all the perforations 15 provided on the first plate portion 13, the second plate portion 14 and the portion on the bottom plate 1 between the first plate portion 13 and the second plate portion 14, all the perforations 15 are evenly distributed on the bottom plate 1, and all the perforations 15 are of the same size, thereby ensuring that the liquid can flow downward evenly, and further allowing the liquid to be evenly distributed on the filler.

[0050] Furthermore, it is worth noting that, in the present embodiment, the distributor is made of carbon fiber material, so that it has high chemical stability and durability, thereby increasing the service life of the distributor which is often in a high temperature, high humidity and corrosive environment. Moreover, the distributor made of carbon fiber material has high mechanical properties, so that the distributor can withstand greater mechanical stress, thereby further increasing the service life of the distributor. In addition, the distributor made of carbon fiber material is light in weight, thereby further reducing the difficulty of assembling the distributor into the tower and reducing the difficulty of subsequent maintenance of the distributor.

[0051] Based on the above, in the present embodiment, two adjacent side panels 21 and the end panel 22 arranged therebetween are fixed by bolt connection, and all the end panels 22 are fixedly connected to the base panel 1 by bolt connection. Specifically, all the end panels 22 are provided with corresponding L-shaped fixing plates 28, and the end panels 22 are bolted to the base panel 1 by the L-shaped fixing plates 28. In addition, the end panels 22 include a plug-in portion 225 and a sealing portion 226, and the plug-in portion 225 is inserted between the two adjacent side panels 21, and the sealing portion 226 is abutted against the outer ends of the two adjacent side panels 21 along the first direction. The side panels 21 are bolted to the plug-in portion 225, thereby assembling to form the enclosure 2 and fixing the enclosure 2 to the base panel 1. It can be understood that, based on the above, this embodiment adopts mortise and tenon joints and bolt connections to assemble the frame 2, and fix the frame 2 on the base plate 1, and at the same time can achieve the sealing of all the first sub-slots 271 and all the second sub-slots 272, as well as the sealing of the liquid separation slot and the first gas phase channel, the liquid separation slot and the second gas phase channel, without the need to use sealants and / or sealing gaskets, etc., thereby preventing the problem of distributor leakage caused by the sealant and / or sealing gasket easily reacting with the medium in the tower.

[0052] From the above, in order to ensure that the bottom plate 1 can stably support the frame 2 and the liquid, in this embodiment, the bottom plate 1 includes a first plate layer 181 and a second plate layer 182, and the second plate layer 182 is arranged at the bottom of the first plate layer 181, that is, in this embodiment, the bottom plate 1 is thickened, thereby ensuring that the bottom plate 1 can stably support the frame 2 and the liquid when the tower diameter is large and the liquid load is heavy, and maintain a high level.

[0053] Based on the above, for the distributor in the prior art, the perforations 15 of the distributor are micropores, so as to ensure that the liquid distribution quality meets the preset requirements. If the perforations 15 maintain the same diameter from the upper surface of the bottom plate 1 to the lower surface of the bottom plate 1, that is, if the perforations 15 maintain a smaller diameter from the upper surface of the bottom plate 1 to the lower surface of the bottom plate 1, due to the increase in the depth of the perforations 15, the fluid model of the liquid flowing along the perforations 15 will change, thereby causing the flow rate of the liquid dripping into the filler to be uncontrollable. To solve this problem, in this embodiment, a first hole portion 1811 is provided on the first plate layer 181, and a second hole portion 1821 is provided on the second plate layer 182. The first hole portion 1811 and the second hole portion 1821 are connected to form the perforation 15, and the diameter of the second hole portion 1821 is The diameter of the first hole portion 1811 is larger than the diameter of the first hole portion 1811, that is, in this embodiment, the first hole portion 1811 still maintains a small diameter, in other words, the first hole portion 1811 is still a micropore, and the second plate layer 182 used for thickening is provided with a second hole portion 1821 with a large diameter. The liquid can flow through the first hole portion 1811 and the second hole portion 1821 in sequence and drip into the filler. Since only the first hole portion 1811 is a micropore in the liquid flow channel, the liquid can enter the large hole after flowing through the first hole portion 1811. Therefore, the fluid model of the liquid flowing along the perforation 15 will not change, that is, the thickening design of the bottom plate 1 in this embodiment will not affect the fluid model of the liquid flowing along the perforation 15, thereby ensuring that the flow rate of the liquid dripping into the filler is still controllable, thereby ensuring that the liquid distribution quality meets the requirements.

[0054] In addition, the present embodiment adopts a thickened design for the bottom plate 1, and the thicker bottom plate 1 is not convenient for directly opening a gas phase channel running from the upper surface to the lower surface to form the through hole 15. The present embodiment can respectively open a first hole portion 1811 on the side of the first plate layer 181 away from the second plate layer 182, and open a second hole portion 1821 on the side of the second plate layer 182 away from the first plate layer 181, thereby facilitating the opening of the through hole 15 on the thickened bottom plate 1, so as to avoid problems such as insufficient precision and increased diameter deviation of the through hole 15, thereby avoiding affecting the quality of liquid distribution.

[0055] For example, in this embodiment, the thickness of the first plate layer 181 is 3 mm, and the thickness of the second plate layer 182 is 5 mm, so that the overall thickness of the bottom plate 1 reaches 8 mm, thereby ensuring that the bottom plate 1 can stably support the frame 2 and the liquid when the tower diameter is large and the liquid load is heavy, and maintain a high level. From above, the depth of the first hole 1811 is 3 mm, and the depth of the second hole 1821 is 5 mm, wherein the diameter of the first hole 1811 is 2.4 mm, and the diameter of the second hole 1821 is 6mm, wherein the first hole portion 1811 is still opened to meet the requirements of high precision and low deviation, while the second hole portion 1821 has no requirements on precision, and it is only necessary to meet the requirement that the diameter of the second hole portion 1821 is larger than the diameter of the first hole portion 1811. With such a design, the liquid can first pass through the first hole portion 1811 with high precision and low deviation, and then pass through the second hole portion 1821 with an enlarged cross section but no interference with the fluid, and then drip into the filler, thereby avoiding affecting the fluid model of the liquid, thereby ensuring that the liquid distribution quality meets the requirements.

[0056] Furthermore, the bottom plate 1 is provided with a slot 16 along its contour, and the frame 2 is placed in the slot 16, so that the frame 2 can be positioned, thereby facilitating the assembly of the frame 2. In addition, in the present embodiment, the frame 2 is also assembled with the bottom plate 1 by mortise and tenon joints, so as to further achieve the sealing of all the first sub-grooves 271 and all the second sub-grooves 272, as well as the sealing of the liquid separation groove and the first gas phase channel, and the liquid separation groove and the second gas phase channel.

[0057] Specifically, a slot structure for placing the side panels 21 and the end panels 22 is defined on the bottom plate 1 , and a worker can alternately place the side panels 21 and the end panels 22 to assemble and form the surrounding frame 2 .

[0058] Moreover, a plurality of milling grooves 19 are provided on the bottom plate 1 , and the plurality of milling grooves 19 correspond to all 90° corners of the slot 16 one by one, so that the slot 16 can be conveniently milled on the bottom plate 1 .

[0059] Furthermore, the base plate 1 is composed of a plurality of plates 17 that are sequentially spliced ​​along the second direction. The process of manufacturing a single plate 17 is relatively simple. Moreover, the present embodiment can obtain the base plate 1 by transporting the plates 17 into the packed tower one by one and assembling them in the tower, thereby reducing the difficulty of assembling the base plate 1 into the tower, and further reducing the difficulty of assembling the distributor into the tower.

[0060] Moreover, along the second direction, the splicing lines 171 between any two adjacent plates 17 are parallel, and the splicing lines 171 between any two adjacent plates 17 are flush with the first gas phase channel and the second gas phase channel, that is, for any two adjacent plates 17, the splicing line 171 is arranged at the bottom of the main groove 273, and the splicing line 171 is arranged corresponding to the first gas phase channel and the second gas phase channel. On the one hand, this embodiment can shorten the splicing line 171, and on the other hand, the splicing line 171 is not located between the first plate portion 13 and the second plate portion 14, thereby further preventing the problem of liquid leakage in the distributor.

[0061] In addition, based on the content mentioned above, the end plate 22 is bolted to the base plate 1 through the L-shaped fixing plate 28, and for the end plate 22 located at the splicing line 171, the L-shaped fixing plate 28 is fixedly connected to both plates 17, thereby fixing several plates 17 to form the entire base plate 1.

Specifically, among the two adjacent plates 17, the first plate layer 181 of one of the plates 17 is protruded outward to form the first boss 172, and the second plate layer 182 of the other plate 17 is protruded outward to form the second boss 173. The first boss 172 overlaps the second boss 173, so that the two plates 17 can be spliced ​​together, that is, in the present embodiment, the bottom plate 1 also adopts a mortise and tenon splicing structure, so as to further prevent the distributor from leaking.

[0063] As described above, the distributor is assembled by special mortise and tenon joints and bolt connections in this embodiment, avoiding the use of sealants and / or gaskets made of resin materials to seal and bond the distributor, eliminating the possibility of the resin reacting with the medium in the tower, thereby reducing the possibility of leakage of the distributor. In addition, the distributor in the present invention has the characteristics of mechanical amplification, so the distributor adopts the principle of mechanical splicing and is applicable to all conditions from small tower diameters to large industrial devices based on the existing raw material sizes.

[0064] It can be understood that a soft belt (not shown in the figure) is provided on the side of the first boss 172 that is in contact with the second boss 173 and / or on the side of the second boss 173 that is in contact with the first boss 172. The soft belt is made of polytetrafluoroethylene material, so that the contact position between the first boss 172 and the second boss 173 can be sealed, thereby further preventing liquid leakage from the distributor.

[0065] Furthermore, the distributor also includes a first crossbeam 31 and a second crossbeam 32, the first crossbeam 31 is arranged at the top of the frame 2 and extends along the second direction, a plurality of first card grooves 311 are arranged on the first crossbeam 31, and the side plates 21 arranged on both sides of the bottom plate 1 along the second direction and all the first plate portions 13 are clamped in the plurality of first card grooves 311, and the two ends of the first crossbeam 31 are respectively fixedly connected to the two side plates 21 located at the outermost sides along the second direction, the second crossbeam 32 is arranged at the top of the frame 2 and extends along the second direction, a plurality of second card grooves 321 are arranged on the second crossbeam 32, and the side plates 21 arranged on both sides of the bottom plate 1 along the second direction and all the second plate portions 14 are clamped in In several second card grooves 321, and the two ends of the second cross beam 32 are respectively fixedly connected to the two outermost side panels 21 along the second direction, the first cross beam 31 can strengthen the side panels 21 arranged on both sides of the bottom plate 1 along the second direction and all the first plate portions 13, thereby avoiding deformation of the side panels 21 arranged on both sides of the bottom plate 1 along the second direction and all the first plate portions 13, and the second cross beam 32 can strengthen the side panels 21 arranged on both sides of the bottom plate 1 along the second direction and all the second plate portions 14, thereby avoiding deformation of the side panels 21 arranged on both sides of the bottom plate 1 along the second direction and all the second plate portions 14, thereby further improving the service life of the distributor.

[0066] In addition, along the second direction, the first plate portion 13 and the corresponding side plates 21 and end plates 22 form a first sub-slot frame, and a first sub-slot 271 is formed in the first sub-slot frame.

The second connecting plate 24 and the first connecting plate 23 work together to avoid changes in the verticality of the first sub-slot frame, thereby further improving the structural stability of the surrounding frame 2.

[0067] It is understandable that, since the second connecting plate 24 is located at the bottom, when assembling the enclosure frame 2, the staff can fix one side of the second connecting plate 24 to the bottom of one of the two adjacent first sub-slot frames in advance, and the other side of the second connecting plate 24 is not fixed, but only needs to be abutted against the other of the two adjacent first sub-slot frames. As for the first connecting plate 23, since the first connecting plate 23 is located at the top, the staff can fix both sides of the first connecting plate 23.

[0068] Correspondingly, along the second direction, the second plate portion 14 and the corresponding side plates 21 and end plates 22 form a second sub-slot frame, and the tops of two adjacent second sub-slot frames are fixedly connected by a third connecting plate 25, thereby fixing all the second sub-slot frames to further improve the structural stability of the surrounding frame 2, thereby further avoiding deformation of the side plates 21, and, in addition, a fourth connecting plate 26 is fixedly connected to the bottom of one of the two adjacent second sub-slot frames, and the fourth connecting plate 26 abuts against the other of the two adjacent second sub-slot frames along the second direction, and the fourth connecting plate 26 is supported between the two adjacent second sub-slot frames, and the fourth connecting plate 26 and the third connecting plate 25 work together to avoid changes in the verticality of the second sub-slot frames, thereby further improving the structural stability of the surrounding frame 2.

[0069] It is also understandable that, since the fourth connecting plate 26 is located at the bottom, when assembling the enclosure frame 2, the staff can fix one side of the fourth connecting plate 26 to the bottom of one of the two adjacent second sub-slot frames in advance, and the other side of the fourth connecting plate 26 is not fixed, but only needs to be abutted against the other of the two adjacent second sub-slot frames. As for the third connecting plate 25, since the third connecting plate 25 is located at the top, the staff can fix both sides of the third connecting plate 25.

[0070] Furthermore, the distributor also includes a third beam 33, which is supported at the bottom of the base plate 1 and extends along the second direction. A fourth beam 34 and a fifth beam 35 are respectively arranged on both sides of the third beam 33 along the first direction.
