AI Technical Summary
During the loading process, the existing fixed bed adsorption tower has a limited number of feeding ports, which causes the filling layer to fluctuate, and cannot ensure the flatness of the filling. Especially in the radial fixed bed adsorption tower, manual intervention is heavy and the working environment is harsh.
A fabric device for an adsorption tower is designed, including a feeding tube and a fabricator. The fabricator is composed of at least two layers of fabric plates arranged at upper and lower intervals. The upper surface of each layer of fabric plate is a convex material contact surface. The height of the material contact surface is lowered from the middle to the surroundings. The material diffuses and falls outward along the circumference of the fabric plate, forming multiple annular blanking areas inside and outside the tower body to improve the uniformity of the filler.
Through this cloth device, the packing can be evenly distributed under the action of gravity, forming multiple continuous annular blanking areas inside and outside, improving the uniformity of the radial distribution of blanking at the same cross-section, reducing manual intervention, and improving loading efficiency.

[0002] Fixed-bed adsorption towers have the advantages of being simple and reliable, and have a wide range of industrial application cases. Generally, the application cycle is relatively long, and the charging method is usually simple and reliable, such as top charging and natural falling. Due to the limited number of charging ports, the fillers on the same height section have uneven ups and downs, and it is impossible to ensure the flatness of filling, so manual raking is often required. Especially for radial fixed-bed adsorption towers, it is more difficult to level the filler layer in the annular interlayer. The larger the tower diameter of the adsorption tower, the more onerous the manual intervention work, the longer the charging time, and the worse the working environment. Summary of the Invention

Detailed implementation mode
[0037] The following specific embodiments illustrate the implementation modes of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.
[0038] Embodiment
[0039] As Figures 1 to 4 shown, in this example, a distribution device for an adsorption tower is exemplified, which is used to distribute materials to the adsorption area in the adsorption tower, including a feeding pipe 5 and a distributor 6. Among them, the feeding pipe 5 is arranged at the top of the tower body 1, above the distributor 6, and is used to feed materials to the distributor 6. An upper feeding device for feeding materials to the feeding pipe 5 of the tower body 1 is also arranged outside;
[0040] The distributor 6 is arranged in the distribution area at the top of the tower body 1 and is used to distribute materials to the space of the tower body 1 below, so that the materials fall into the lower space evenly and dispersedly; the distributor 6 includes at least two layers of distribution plates arranged at intervals up and down. The upper surface of each layer of distribution plate is a convex material contact surface, and the height of the material contact surface decreases from the middle to the periphery, that is, the vertical projection contour can be inclined or arc-shaped; the distribution plate is used to receive materials from the feeding pipe 5 and make the materials spread and fall around along the distribution plate under the action of gravity.
[0041] Materials (packing or adsorbent) are sent to the upper part of each layer of distribution plate through the feeding pipe 5. When the materials fall to the top in the middle of the distribution plate, they spread outwards along the periphery of the distribution plate and fall; at least two annular material falling areas are formed along the radial direction (inside and outside direction) of the tower body 1 in the adsorption area (i.e., below the distribution plate) in the tower body 1, and the material falling area corresponding to the upper layer distribution plate 61 is located outside the material falling area corresponding to the lower layer distribution plate 62. Each material falling area can basically cover the cross-sectional area of the tower body 1, so that the material falling is uniform.
[0042] Adsorption packing is sent through the feeding pipe 5. Under the action of gravity, the packing falls onto the upper surface of the corresponding distribution plate and then spreads from the middle of the distribution plate to the periphery and falls in a parabola shape, forming multiple continuous annular material falling areas inside and outside in the tower body 1 below the distribution plate, improving the uniformity of the radial distribution of the material falling at the same cross-sectional height. The more material falling areas are formed along the radial direction, the more uniform the distribution is.
[0043] Among them, a cloth space with a height decreasing from the middle to the surroundings is formed between adjacent two layers of cloth plates, and a cloth space with a height decreasing from the middle to the surroundings is also formed between the topmost cloth plate and the inner wall of the top of the tower body 1 (i.e., a cloth channel with feeding in the middle and discharging at the surroundings). Each of the cloth spaces corresponds to an annular blanking area, and adjacent two layers of cloth plates define the radial coverage range of the blanking area corresponding to the cloth space formed by them. That is, the lower layer of cloth plate defines the inner circle size of the corresponding annular blanking area, and the upper layer of cloth plate defines the outer circle size of the corresponding annular blanking area. That is, in addition to playing a role in dispersing the cloth, the upper layer of cloth plate also plays a role in restricting the coverage range of the blanking area corresponding to the lower cloth space. By changing the inclination angle of the cloth plate, or the interval between the upper and lower cloth plates, or the radial dimension of the cloth plate, the coverage range of the blanking area can be adjusted; that is, the blanking coverage range is related to the width at the outlet of the cloth space.
[0044] Of course, due to the fluidity or inertia of the material, the materials at the adjacent positions of the inner and outer annular blanking areas may flow into each other and there may be partial intersection, which is more conducive to the radial uniformity of the cloth.
[0045] In one embodiment, the upper surface of the cloth plate is a spherical surface, an arc surface or a conical surface. As Figure 1 and Figure 2 shown, the cloth plate is a spherical structure that gradually decreases from the middle top to the surroundings; as Figure 5 shown, the upper surface of the cloth plate is a conical structure that gradually decreases from the middle top to the surroundings. It can also be that one section is an arc surface and the other section is a conical surface; or the upper layer is a spherical surface and the lower layer is a conical surface, etc.
[0046] In one embodiment, each layer of cloth plates is arranged coaxially up and down with the axis of the tower body 1 as the center; since the tower body 1 is generally a cylindrical structure and the cloth plates are also circular structures; the outer diameter dimensions of each layer of the cloth plates decrease successively from the upper layer to the lower layer, that is, the outer diameter dimension of the upper layer of cloth plate is larger than that of the lower layer of cloth plate, so as to form continuous inner and outer blanking areas.
[0047] In one embodiment, the inclination angles or radian measures of each layer of the cloth plates are the same; or, the inclination angles or radian measures of each layer of the cloth plates are different and can be set according to needs.
[0048] When the cloth plate is a spherical structure, the radian measure of the bow-shaped cross-section of the vertical projection of the cloth plate is less than or equal to 180°, that is, the cross-sectional contour is less than or equal to a semi-circle.
[0049] In one embodiment, the feeding pipe 5 includes at least two layers of coaxial sleeves arranged inside and outside, and the discharge ports of each layer of sleeves extend downward to above the corresponding cloth plate; as Figure 1 and Figure 2As shown, in this example, three upper and lower fabric plates and corresponding three sleeves are schematically shown. In other embodiments, to improve uniformity, more fabric plates and sleeves can be provided to form a denser fabric area.
[0050] As Figure 2 and Figure 3 shown, the feeding pipe 5 includes a first sleeve 51, a second sleeve 52, and a third sleeve 53 arranged coaxially from outside to inside. The fabricator 6 includes an upper fabric plate 61, a middle fabric plate 62, and a lower fabric plate 63 arranged successively from top to bottom, forming three independent fabric spaces, namely fabric space A, fabric space B, and fabric space C; three inner and outer blanking areas, namely blanking area a, blanking area b, and blanking area c, are formed in the adsorption area below the fabricator 6; the lower discharge port of the first sleeve 51 extends into the upper part of the fabric space A and is sealed with the tower body 1; the lower discharge port of the second sleeve 52 extends into the upper part of the fabric space B, and the lower discharge port of the third sleeve 53 extends into the upper part of the fabric space C.
[0051] Taking the radial flow adsorption tower as an example, the uppermost upper fabric plate 61 is installed on the inner wall of the tower body 1. In this example, the lower fabric plate 63 is connected to the upper end of the material sealing ring pipe 3 of the tower body 1, and the upper end of the inner ring air flow channel 4 of the adsorption tower is connected to the lower end of the material sealing ring pipe 3, so that there is no air flow passing through the radial adsorbent area (adsorption layer) within the height of the material sealing ring pipe 3. The fabric plates of other layers are installed on the sleeves corresponding to the lower layer fabric plates, that is, the middle fabric plate 62 is installed on the third sleeve 53, and the upper fabric plate 61 is installed on the second sleeve 52, as Figure 1 and Figure 2 shown.
[0052] As shown in 7 and Figure 8 shown, in one embodiment, each layer of fabric plate can also be supported on the inner wall of the tower body 1 by a bracket 9 (not shown in the figure); in another embodiment, the upper layer of fabric plate is supported on the lower layer of fabric plate by a bracket 9. For example, the middle fabric plate 62 is supported on the lower fabric plate 63 by a bracket, and the upper fabric plate 61 is supported on the middle fabric plate 62 by another bracket 9; the above various installation methods can be used alone or in combination, and the brackets and the like can be made of section steel, steel bars, etc. to reduce or avoid blocking the material. The bracket can correspond to the position of the guide strip 7, so that the blocking can be further reduced. Figure 9 Figure 21 is a bottom view of the lowest layer of fabric plate supported on the inner wall of the tower body by a bracket 9. The fabric plates of other layers can be supported on the inner wall of the tower body by other brackets or supported on the lower layer.
[0053] To facilitate the feeding of the material, the upper inlet of the feeding pipe 5 (sleeve) is a conical hopper structure with a large upper part and a small lower part.
[0054] In one embodiment, the height of the cloth plate is relatively fixed with respect to the tower body 1, and the interval between adjacent cloth plates is relatively fixed and non-adjustable.
[0055] In one embodiment, for facilitating the adjustment of the coverage range of the blanking area, the height of the cloth plate is adjustable with respect to the tower body 1, and the interval between adjacent cloth plates is adjustable. For Figure 1 and Figure 5 as shown in the figure, there are two implementation manners: the cloth plate is sleeved outside the sleeve pipe and fixedly connected to the sleeve pipe, and a lifting adjustment mechanism is connected to the upper end of the sleeve pipe. The lifting adjustment mechanism can be a hydraulic cylinder, a lifting structure driven by a motor, etc., which is connected to the sleeve pipe so as to drive the sleeve pipe and the corresponding cloth plate to lift;
[0056] or the sleeve pipe is fixed on the tower body 1, and the position between the cloth plate and the sleeve pipe can be adjusted vertically. For example, the cloth plate is sleeved outside the sleeve pipe and threadedly connected to the sleeve pipe, so as to realize up and down adjustment; or a plurality of installation positions are axially arranged on the sleeve pipe, and the cloth plate is detachably installed on one of the installation positions through a clamp or a bolt, etc.
[0057] In one embodiment, to ensure uniform blanking and avoid the formation of channel flow of the loaded adsorbent on the upper surface of the cloth plate, a plurality of guide strips 7 are circumferentially and spacedly arranged on the upper surface of the cloth plate. Each guide strip 7 is parallel to the generatrix direction of the cloth plate, that is, the length direction of the guide strip 7 is along the generatrix direction, and the projection of the guide strip 7 along the radial direction is to improve the circumferential uniformity, and the guide strips 7 of adjacent two layers or each layer are staggered in the circumferential direction, as Figure 4 shown.
[0058] As Figure 6 and Figure 7 shown, in one embodiment, when applied to a radial flow adsorption tower, the center of the top of the lowermost cloth plate is sealed, the center of the top of other cloth plates is provided with an opening 8, and the opening 8 of the upper cloth plate is larger than the opening 8 of the lower cloth plate, so that the lower cloth plate can receive materials through the opening 8 of the upper layer, and the feeding pipe 5 naturally falls downward by gravity through the openings 8 of each layer of cloth plates.
[0059] As Figure 7 shown, in this embodiment, the feeding pipe 5 is one, and its inner diameter is larger than the diameter of the opening 8 of the uppermost cloth plate 61. After the materials are fed into the feeding pipe 5, they fall to the periphery of the openings 8 of each layer of cloth plates and fall along the cloth plates; or the feeding pipe 5 includes a plurality of coaxial inner and outer sleeve pipes, and the aperture of each sleeve pipe is larger than the diameter of the opening 8 of the corresponding cloth plate for feeding, as Figure 6 shown, and the materials fall to the periphery of the corresponding opening 8 of the corresponding cloth plate through the corresponding sleeve pipe.
[0060] When applied to an axial-flow adsorption tower, the structure of the cloth-feeding device in any of the above embodiments can be adopted. The difference is that openings 8 are provided at the top of the lowermost cloth-feeding plate to feed materials to the middle position. More cloth-feeding plates for feeding materials to the middle position of the tower body 1 can be provided to form more material dropping areas at the center of the tower body 1 so as to cover all areas, such as Figure 8 、 Figure 10 、 Figure 12 and Figure 13 shown.
[0061] The present invention also provides an adsorption tower, including the above cloth-feeding device. The adsorption tower is a radial-flow adsorption tower or an axial-flow adsorption tower. The radial-flow adsorption tower means that the gas flows into and out of the adsorbent layer radially, that is, when flowing through the adsorbent layer, the main flow direction of the gas is perpendicular to the axial direction of the tower body; the axial-flow adsorption tower means that the gas flows into and out of the adsorbent layer axially. When setting the cloth-feeding device, it is only necessary not to interfere with the inlet and outlet. Figure 1 、 Figure 5 and Figure 11 are schematic diagrams of a radial-flow adsorption tower, Figure 11 the inlet and outlet of which can be swapped; Figure 8 and Figure 10 are schematic diagrams applied to an axial-flow adsorption tower, Figure 12 and Figure 13 are schematic diagrams of an axial-flow adsorption tower; generally, the adsorption tower is loaded from the top of the tower body. The middle part of the tower body is the adsorption zone (also called the adsorption section, adsorption layer), and the bottom of the tower body is the material dropping area for discharging waste materials; the cloth-feeding device in this example is for feeding materials to the adsorption zone so that the adsorbent is evenly distributed in the adsorption zone.
[0062] In the above embodiments, when the feeding pipe 5 is a plurality of coaxial sleeves, it is possible to choose to feed materials through all the sleeves together, or only choose to feed materials through one or two of the sleeves. Generally, at the initial stage of feeding, the adsorbent can be added through all the sleeves together and fall onto the surfaces of the upper cloth-feeding plate 61, the middle cloth-feeding plate 62, and the lowermost cloth-feeding plate 63. After naturally spreading out, it is evenly divided into the material dropping areas a, b, c of the lower adsorption bed layer and gradually fills up from bottom to top. During this process, there may be differences in the material level heights of the material dropping areas a, b, c along the circumferential direction of the tower body 1. At this time, choose to feed materials only through the sleeve corresponding to the material dropping area with a low material level until the deviation disappears. After the feeding is completed, the feeding pipe 5 is closed. After completing necessary safety measures such as purging and replacement, the gas enters the adsorption bed layer radially through the inner ring gas flow channel 4 of the radial-flow adsorption tower, removes harmful substances such as chlorine and sulfur, enters the gas collecting chamber 2, and flows out from the gas outlet to complete purification.
[0063] Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the present invention shall still be covered by the claims of the present invention.
