Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a method for separating, purifying, or concentrating a gas that is easily adsorbed on an adsorbent or a gas that is hardly adsorbed from a mixed gas by using a pressure fluctuation adsorption (PSA) method or a heat fluctuation adsorption (TSA) method. It 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 adsorbent is placed in the adsorption tank using the PSA method or the TSA method. An adsorption device filled with is often used. FIG. 6 shows an example of such a conventional suction device.
[0003]
As shown in FIG. 6, the adsorption tower 101 has an upper gas passage 102 and a lower gas passage 103. Below the inside of the adsorption tower 101, a perforated plate 150a having a plurality of through holes is provided, and the upper surface of the perforated plate 150a is covered with a wire net 150b. An alumina particle layer 108, a zeolite layer 107, and a ceramic ball layer 106 are formed on the perforated plate 150a whose top surface is covered with a wire mesh 150b, with the wire meshes 109a and 109b interposed therebetween. The ceramic ball layer 106 is provided in order to suppress the adsorbent forming the alumina particle layer 108 and the zeolite layer 107 formed as an adsorption layer from being fluidized by the rising gas flow.
[0004]
In such an adsorption device, when the mixed gas is fed into the adsorption tower 101 from the lower gas passage 103, the mixed gas flows through the through holes of the perforated plate 150a and the wire mesh 150b, and flows into the alumina particle layer 108 and the zeolite layer 107. A predetermined gas component (for example, water vapor and nitrogen in the air) in the mixed gas is selectively adsorbed by each adsorbent in the alumina particle layer 108 and the zeolite layer 107. The gas not 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]
When the adsorption of the predetermined gas component by each of the adsorbents filled in the alumina particle layer 108 and the zeolite layer 107 becomes saturated as described above, the supply of the mixed gas is stopped, and the adsorption from the upper gas passage 102 is stopped. By sending 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 outlet 103 to the outside of the adsorption tower 101 to be collected. 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 the amount of the processing gas, a method of increasing the filling height or a method of increasing the bed area of the adsorbent bed can be considered. However, in the method of increasing the filling height, the resistance when the mixed gas passes through the adsorbent increases, so that the pressure loss increases.If the power required for the adsorption treatment is not increased, the treatment speed can be increased. Can not. In addition, the method of increasing the floor area of the adsorbent bed is disadvantageous in that the installation area of the adsorption device is increased, and also increases the possibility that the gas passing through the adsorbent layer will drift.
[0007]
As an example of an adsorption device that can increase the amount of processing gas without increasing power consumption and installation area, it is necessary to provide a vertical adsorption layer in the adsorption tower and flow the mixed gas horizontally from the side of the adsorption tower. An apparatus for separating and purifying a gas is known. (For example, refer to Patent Document 1.)
[0008]

[Problems to be solved by the invention]
However, in the adsorption device disclosed in Patent Document 1, the adsorption tower is filled with the adsorbent by inverting the adsorption tower sideways and introducing the adsorbent through an adsorbent introduction pipe provided on a side surface of the adsorption tower. Be done. Therefore, the introduction of the adsorbent is very troublesome, and a plurality of adsorbent introduction tubes are required to uniformly fill the adsorbent, which is disadvantageous in cost and work efficiency. In addition, if the adsorption tower is installed vertically and the adsorption operation is repeated after filling the adsorbent, the adsorbent layer is compressed. Therefore, it is necessary to provide a sealing structure with a pressurizing device at the head of the adsorption tower in order to prevent the gas from passing through the space at the head of the adsorption tower caused thereby, and the structure is complicated. Further, when actually separating and refining the mixed gas 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, gas flows more easily to the adsorbent layer near the gas inlet and gas outlet (at the center in the height direction of the adsorption tower) due to the apparatus configuration. Therefore, it is considered that the mixed gas drifts with respect to the adsorbent layer, and the adsorbent near the upper end and the lower end of the adsorbent layer cannot be fully utilized.
[0010]
The present invention has been conceived under such circumstances, and provides an adsorber that does not have the above-described problems, is compact, has a simple structure, and can increase a processing gas amount. The purpose is to.
[0011]
[Means for Solving the Problems]
In order to solve the above problems, the present invention takes the following technical measures.
[0012]
That is, according to the first aspect of the present invention, the adsorption device includes an upper gas passage, a lower gas passage, and an intermediate gas passage provided on a side wall between the upper gas passage and the lower gas passage. A gas-passing space provided by supporting a cylindrical adsorption tower provided with 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, is capable of moving up and down along the inner surface of the side wall, and is provided so that the intermediate gas passage opening and the gas passage space communicate with each other; Fillers filled on both upper and lower sides of the partition structure.
[0013]
By providing the partition structure, the adsorption tower is divided into two parts. Therefore, it is possible to obtain the same effect as securing twice the area for treating the mixed gas as compared with an adsorption tower of the same size having no 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 is likely to occur in the adsorption tower having a large diameter. That is, it is possible to provide a compact adsorption device having a large amount of processing gas. Furthermore, by dividing the filler by the partition structure, the filling height of the filler at each of the upper and lower portions of the partition structure can be reduced, so that compared to the case where the cumulative flow resistance due to the filler 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 own weight of the partition structure and the weight of the filler filled above the partition structure. As a result, the filler filling the lower side of the partition structure becomes compacted due to vibration or gas flow during operation, and even if the layer is compressed, the filler is filled under the partition structure and the lower side of the partition structure. A space can be prevented from being formed with the filled 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]
Further, the filler in the adsorption tower can be filled in order from the upper gas passage, for example, with the adsorption tower installed vertically. Therefore, there is no need to tilt the adsorption tower sideways when filling the packing material, or to separately provide an inlet for introducing the packing material on the side of the adsorption tower, which is excellent in cost and work efficiency. ing.
[0016]
Preferably, the first and second partition members have a seal structure including a sealant for preventing the 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 movement of the filler through the gap between the first and second partition members and the inner surface of the side wall. It becomes. Therefore, the processing of the mixed gas can be performed more effectively, and problems such as outflow of the filler can be suppressed. The first and second partition members are preferably made of a flat metal mesh, a perforated plate, or a laminate of 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 formed so as to be symmetrical above and below the partition structure. By laminating the filler so as to be symmetrical above and below the partition structure, it is possible to suppress a difference in the filling state of the filler above and below the partition structure, that is, to suppress a gas single 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 dispersion balls and a layer made of at least one adsorbent.
[0019]
According to the second aspect of the present invention, the adsorption device comprises a plurality of upper gas passages, a lower gas passage, and a plurality of vertically spaced side walls provided between the upper gas passage and the lower gas passage. A tubular adsorption tower having an intermediate gas passage, 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 structures including a plurality of support members for forming a passage space, and movable up and down along an inner surface of a side wall provided so that the intermediate gas passage and the gas passage space communicate with each other. And fillers filled on both upper and lower sides of each partition structure.
[0020]
With this 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 structures. Therefore, the same effect as securing the area for processing the mixed gas four times as compared with an adsorption tower of the same size having no partition structure is obtained, and the diameter of the adsorption tower itself is increased. Therefore, it is possible to suppress an increase in installation area and a drift of gas that is likely to occur in an adsorption tower having a large diameter. Therefore, it is possible to provide a compact adsorption device having a large processing gas amount. Further, by dividing the adsorption tower into four or more parts, the filling height of the packing material can be further reduced, so that the flow resistance due to the packing material is reduced.

Note that the order of filling the second filler layers 7a and 7b and the third filler layers 8a and 8b may be changed according to the gas flow direction or the like.
[0034]
Although the present embodiment has been described as an adsorption apparatus suitable for producing oxygen from air by the PSA method or the TSA method, the present invention is not limited to the above-described one. It is also applicable to the separation and purification and concentration of gases such as hydrogen, carbon dioxide, methane, and moisture.
[0035]
In the adsorption apparatus X1 having the above configuration, the provision of the partition structure 5 divides the adsorption tower 1 into upper and lower sides. Therefore, as compared with an adsorption tower of the same size in which the partition structure 5 is not provided, an effect similar to that of securing twice the area for processing the mixed gas is obtained, and the diameter of the adsorption tower 1 itself is increased. Therefore, it is possible to prevent an increase in installation area and a drift of gas which is likely to occur in an adsorption tower having a large diameter. That is, it is possible to provide a compact adsorption device having a large amount of processing gas. In addition, by separating the filler layers 6a, 7a, 8a and the filler layers 6b, 7b, 8b with the partition structure 5, the filling height of the filler at each of the upper and lower portions of the partition structure 5 can be reduced. The flow resistance due to the packing material is reduced as compared to the case where the flow resistance due to the packing material is received over almost the entire height of the adsorption tower. Further, since the partition structure 5 can be moved up and down, the partition structure 5 can be moved downward by its own weight and the weight of the filler filled in each of the filler layers 6b, 7b, 8b. . Therefore, each of the filler layers 6a, 7a, 8a becomes compacted due to vibration or gas flow during operation, and even when the layers are compressed, for example, between the partition structure 5 and the third filler layer 8a. The formation of a space can be prevented. Therefore, it is not necessary to separately provide a pressurizing device or the like in order not to generate the space, and the configuration of the device can be simplified. Further, each of the filler layers 6a, 6b, 7a, 7b, 8a, 8b in the adsorption tower 1 is formed by filling the filler sequentially from the upper gas passage 2 with the adsorption tower 1 installed vertically. It can be carried out. Therefore, it is not necessary to tilt the adsorption tower 1 sideways when filling the packing material, or to separately provide an inlet for introducing the packing material on the side surface 10 of the adsorption tower 1, and it is possible to reduce cost and work efficiency. Are better.
[0036]
By providing the seal structure 53 on the first and second partition members 50 and 51, the movement of the filler through the gap between the first and second partition members 50 and 51 and the inner surface 10a of the side wall 10 is prevented. Can be prevented. Therefore, the processing of the mixed gas can be performed more effectively, and problems such as outflow of the filler can be suppressed. Further, by providing the seal structure 53, the dimensional accuracy between the first and second partition members 50 and 51 and the side wall 10 of the adsorption tower 1 does not have to be strictly required.
[0037]
By laminating each of the filler layers 6a, 6b, 7a, 7b, 8a, 8b so as to be symmetrical above and below the partition structure 5, the difference in the filling state of the filler above and below the partition structure 5, that is, One-sided flow of gas due to a difference in flow resistance can be suppressed. Therefore, the mixed gas can be more effectively processed.
