Description

[0001]
BACKGROUND OF THE INVENTION
The present invention uses a pressure fluctuation adsorption (PSA) method or a heat fluctuation adsorption (TSA) method to separate, purify, or concentrate a gas that is easily or hardly adsorbed by an adsorbent from a mixed gas. The present invention relates to an adsorption device.
[0002]
[Prior art]
When separating, purifying or concentrating gases such as nitrogen, oxygen, hydrogen, carbon dioxide, methane and moisture contained in the mixed gas, the PSA method or TSA method is used to place the adsorbent in the adsorption tank. Adsorbers filled in are often used. An example of such a conventional adsorption apparatus is shown in FIG.
[0003]
As shown in FIG. 6, the adsorption tower 101 has an upper gas passage port 102 and a lower gas passage port 103. A perforated plate 150a having a plurality of through holes is provided below the inside of the adsorption tower 101, and the upper surface of the perforated plate 150a is covered with a metal mesh 150b. An alumina particle layer 108, a zeolite layer 107, and a ceramic ball layer 106 are laminated on the perforated plate 150a whose upper surface is covered with a metal mesh 150b via metal mesh 109a and 109b. The ceramic ball layer 106 is provided in order to prevent the adsorbent constituting the alumina particle layer 108 and the zeolite layer 107 formed as the adsorption layer from fluidizing with the rising gas flow.
[0004]
In such an adsorption apparatus, when the mixed gas is fed into the adsorption tower 101 from the lower gas passage port 103, the mixed gas flows through the through hole of the perforated plate 150a and the metal mesh 150b and flows into the alumina particle layer 108 and the zeolite layer 107. A predetermined gas component in the mixed gas (for example, water vapor and nitrogen in the air) is selectively adsorbed by the adsorbents in the alumina particle layer 108 and the zeolite layer 107. The gas that has not been adsorbed passes through the ceramic ball layer 106 and is discharged from the upper gas passage 102 to the outside of the adsorption tower 101.
[0005]
In this way, when the adsorption of the predetermined gas component by each adsorbent filled in the alumina particle layer 108 and the zeolite layer 107 is saturated, the supply of the mixed gas is stopped, while the adsorption from the upper gas passage port 102 is performed. By feeding a purge gas into the tower 101, a predetermined gas component adsorbed by each adsorbent is desorbed from the adsorbent, and discharged from the lower gas passage 103 to the outside of the adsorption tower 101 for recovery. By repeating the above operation, a predetermined gas component can be purified from the mixed gas.
[0006]
In the adsorption apparatus having such a configuration, as a method of increasing the adsorption capacity or increasing the amount of processing gas, a method of increasing the filling height or a method of increasing the floor area of the adsorbent bed can be considered. However, in the method of increasing the filling height, the pressure loss increases because the resistance when the mixed gas passes through the adsorbent increases, and the processing speed can be increased unless the power required for the adsorption treatment is increased. Can not. In addition, the method of increasing the floor area of the adsorbent bed is disadvantageous because the installation area of the adsorption device is increased, and the possibility that the gas passing through the adsorbent layer drifts increases.
[0007]
As an example of an adsorption device that can increase the amount of processing gas without increasing the power consumption and installation area, a vertical adsorption layer is provided in the adsorption tower, and the mixed gas flows in from the side of the adsorption tower in the horizontal direction. Devices for separating and purifying gas are known. (For example, refer to Patent Document 1.)
[0008]
[Patent Document 1]
JP-A-5-146624 [0009]
[Problems to be solved by the invention]
However, in the adsorption apparatus disclosed in Patent Document 1, the adsorption column is filled with the adsorbent by introducing the adsorbent from the adsorbent introduction pipe provided on the side surface of the adsorption tower while the adsorption tower is turned sideways. Is called. Therefore, the introduction of the adsorbent is very troublesome, and a plurality of adsorbent introduction pipes are required to uniformly fill the adsorbent, which is disadvantageous in terms of cost and work efficiency. In addition, if the adsorption operation is repeated after the adsorbent is filled and the adsorption tower is installed vertically, the adsorbent layer is compressed. Therefore, in order to prevent gas from passing through the space of the adsorption tower head generated thereby, it is necessary to provide a seal structure with a pressurizing device at the adsorption tower head, and the structure is complicated. Further, when the mixed gas is actually separated and purified using the adsorption device, the gas is introduced so that the mixed gas introduced from the gas inlet provided on the side surface of the adsorption tower is uniformly introduced into the adsorbent layer. Although a distribution collector is provided, the gas flows more easily to the adsorbent layer in the vicinity of the gas inlet and the gas outlet (in the center in the height direction of the adsorption tower) due to the device configuration. Therefore, the mixed gas drifts with respect to the adsorbent layer, and it is considered that the adsorbent near the upper end and lower end of the adsorbent layer cannot be fully utilized.
[0010]
The present invention has been devised under such circumstances, and provides an adsorption device that does not have the above-described problems, is compact and simple in structure, and can increase the amount of processing gas. For the purpose.
[0011]
[Means for Solving the Problems]
In order to solve the above problems, the present invention takes the following technical means.
[0012]
That is, according to the first aspect of the present invention, the adsorption device includes an upper gas passage opening, a lower gas passage opening, an intermediate gas passage opening provided on a side wall between the upper gas passage opening and the lower gas passage opening. A gas passage space by supporting a cylindrical adsorption tower, a first partition member having gas permeability, a second partition member having gas permeability, and a first partition member and a second partition member. A partition structure provided with a plurality of support members for forming a portion, movable up and down along the inner surface of the side wall, and provided so that the intermediate gas passage port and the gas passage space portion communicate with each other. And a filler filled on both upper and lower sides of the partition structure.
[0013]
By providing the partition structure, the adsorption tower is divided into two. Therefore, it is possible to obtain the same effect as securing twice the area for processing the mixed gas as compared with the same size adsorption tower not provided with the partition structure, and to increase the diameter of the adsorption tower itself. Therefore, it is possible to prevent an increase in the installation area and a gas drift that easily occurs in an adsorption tower having a large diameter. That is, it is possible to provide an adsorption device that is compact and has a large amount of processing gas. Furthermore, by dividing the packing material with the partition structure, the packing height of the packing material at each of the upper and lower sides of the partition structure can be reduced, so that compared with the case where the cumulative flow resistance due to the packing material is applied over almost the entire height of the adsorption tower. The flow resistance due to the filler is reduced.
[0014]
In addition, since the partition structure can be moved up and down, the partition structure can be moved downward by the weight of the partition structure and the weight of the filler filled above the partition structure. For this reason, even when the filler filled in the lower side of the partition structure becomes compacted due to vibration or gas flow during operation and the layer is compressed, the partition structure and the lower side of the partition structure are filled. It is possible to prevent a space from being formed with the filler. Therefore, it is not necessary to separately provide a pressurizing device or the like so as not to generate the space, and the configuration of the device is simplified.
[0015]
Furthermore, the packing material in the adsorption tower can be filled in order from the upper gas passage port, for example, with the adsorption tower installed vertically. Therefore, there is no need to lay the adsorption tower sideways when filling the packing material or to provide a separate inlet for introducing the packing material on the side of the adsorption tower, which is excellent in terms of cost and work efficiency. ing.
[0016]
Preferably, the first and second partition members have a seal structure including a seal material for preventing movement of the filler between the first and second partition members and the inner surface of the side wall.
[0017]
By providing the first and second partition members with the seal structure provided with the seal material, it is possible to prevent the filler from moving through the gap between the first and second partition members and the inner surface of the side wall. It becomes. Therefore, the mixed gas can be processed more effectively, and problems such as the outflow of the filler can be suppressed. In addition, it is preferable that a 1st and 2nd partition member consists of a laminated sheet of a flat metal mesh, a perforated plate, or a flat metal mesh and a perforated plate.
[0018]
Preferably, the filler forms a plurality of layers above and below the partition structure, and the layers of the filler are laminated so as to be symmetrical above and below the partition structure. By stacking the fillers so as to be symmetrical above and below the partition structure, it is possible to suppress a difference in the filling state of the fillers above and below the partition structure, that is, to suppress a single gas flow caused by a difference in flow resistance. it can. Therefore, the mixed gas can be more effectively processed. As the filler, it is preferable to form a layer made of gas dispersing balls and a layer made of at least one adsorbent.
[0019]
According to the second aspect of the present invention, the adsorption device includes a plurality of upper and lower gas passage ports, a plurality of gas passages provided on the side walls between the upper gas passage port and the upper gas passage port and the lower gas passage port. A cylindrical adsorption tower having an intermediate gas passage port, a first partition member having gas permeability, a second partition member having gas permeability, and a gas between the first partition member and the second partition member A plurality of partition members that can move up and down along the inner surface of the side wall provided so as to communicate with the intermediate gas passage port and the gas passage space portion. And a filler filled on both upper and lower sides of each partition structure.
[0020]
By adopting such a configuration, for example, when three intermediate gas passage ports and three partition structures are provided, the adsorption tower is divided into four by the partition structure. Therefore, it is possible to obtain the same effect as securing the mixed gas processing area four times as large as the adsorption tower of the same size without the partition structure, and to increase the diameter of the adsorption tower itself. no, it is possible to suppress nonuniform flow of easy gas generated in the adsorption tower having an increased or greater diameter of the footprint. Therefore, it is possible to provide an adsorption device that is compact and has a larger amount of processing gas. Further, by dividing the adsorption tower into four or more, the filling height of the filler can be made smaller, so that the flow resistance due to the filler is also reduced.

Can be prevented. Therefore, the mixed gas can be processed more effectively, and problems such as the outflow of the filler can be suppressed. Further, since the seal structure 53 is provided, the dimensional accuracy between the first and second partition members 50 and 51 and the side wall 10 of the adsorption tower 1 is not strictly required.
[0037]
By stacking the filler layers 6a, 6b, 7a, 7b, 8a, and 8b so as to be symmetric with respect to the top and bottom of the partition structure 5, the difference in the filling state of the fillers above and below the partition structure 5, that is, It is possible to suppress a single gas flow caused by a difference in flow resistance. Therefore, the mixed gas can be more effectively processed.
