Abstract

PURPOSE:To facilitate the partial replacement of an adsorbing material, by constituting the titled apparatus so that adsorbing materials each molded into a cylindrical form are stacked and gas to be treated is alternately flowed through inner flow passages and outer passages. CONSTITUTION:A large number of adsorbing materials 1 each molded into a cylindrical form are stacked in a cylindrical container 2 through plate shaped partitions 3 and ring shaped partitions 4 to form inner flow passages inside the adsorbing materials and outer flow passages between the outsides of the adsorbing materials 1 and the inner wall of the container 2 and a gaseous mixture is alternately passed through the inner flow passages and the outer flow passages. By this method, the gas to be treated passed through the adsorbing materials 1 without short-pass and sufficient adsorptive separation can be performed and the adsorbing materials can be partially taken out.

の低下が避λ Cloth Shell Force [Industrial Application Field] The present invention relates to an improvement in a gas adsorption separation device using a selective adsorbent. [Prior Art] For example, one method for separating oxygen and nitrogen in the air is to adsorb and remove nitrogen using a selective adsorbent such as zeolite to obtain an oxygen-enriched gas. In order to use adsorbents effectively, it is necessary to repeat adsorption and desorption, and as is well known, there are pressure swing methods and temperature swing methods. The gas adsorption separation apparatus conventionally used to carry out these methods is one filled with granular or pellet-shaped adsorbents at an appropriate density. However, there are problems in that the adsorbent materials rub against each other due to pressure swings, resulting in powdering or a decline in functionality. This is a problem to varying degrees in the temperature swing method as well. Either method avoids a decrease in contact efficiency with the adsorbent due to uneven flow of the gas to be treated.

Additionally, if the device is placed horizontally, there will be a gap at the top, which may cause a short path for the gas. Furthermore, if the performance of the adsorbent deteriorates due to moisture absorption or other causes, it is necessary to take it out and regenerate it, but it is difficult to take out only the adsorbent from the inlet portion, which is prone to deterioration. [Problem to be solved by the invention] The purpose of the present invention is to solve the above-mentioned problems, to ensure that the gas to be treated always passes through the adsorbent to ensure smooth selective adsorption, and to replace only the adsorbent at the gas inlet where performance tends to deteriorate. An object of the present invention is to provide a gas adsorption separation device that can be regenerated. Five bowls of plates [Means to solve the problem]

ある。The gas adsorption separation device of the present invention is a device that separates gas by selectively adsorbing a specific gas in a mixed gas, as shown in FIG. , stacked in a cylindrical container 2 via a plate-shaped partition 3 and an annular partition 4, with an internal flow path 5 inside each adsorbent and an external flow path between the outside of each adsorbent and the inner wall of the container. It is characterized in that a passage 6 is formed so that the mixed gas passes through the internal passage and the external passage alternately. (Function) By making the adsorbent into a molded body, there is no need to worry about deterioration caused by friction due to pressure or temperature swings, which is the case with particles or pellets.The porosity of the molded body can be freely controlled within a certain range. Since the adsorbent is completely divided into many segments by partitions, the gas to be treated passes through the adsorbent without short-passing, and sufficient adsorption separation is performed. The adsorbent can be partially taken out. [Example] Zeolite powder was molded to prepare a cylindrical adsorbent having an outer diameter of 77 m, an inner diameter of 19 Nn, a height of 70 m, and a weight of approximately 2,509 kg as shown in Fig. 2. Four pieces of this were prepared. , 8, 12, 16 or 20 pieces were used to assemble a gas adsorption separation device with the structure shown in Figure 1. This device was operated under the following conditions to obtain concentrated oxygen from air (as described in the Example) Pressure adsorption Adsorption pressure 0.6 Kg/cri G
Decompression desorption Desorption pressure -60CIRHg cycle
120 sec For comparison, the same number of adsorbent molded bodies were used, however, an apparatus was configured in which all of the gas to be treated flows from the inside to the outside, and oxygen was concentrated under the same conditions (Comparative Example 1) . In addition, a packed tower was constructed using spherical zeolite with a particle size of 4 to 18 mesh in a weight corresponding to the number of molded bodies, and gas adsorption separation was attempted under the same conditions (Comparative Example 2
). The graph in FIG. 2 shows the relationship between the number of zeolite molded bodies and the oxygen concentration of the obtained concentrated gas. From this graph, it is clear that the apparatus of the present invention has the highest separation efficiency. Although the present invention has been described above with respect to the case of obtaining oxygen-enriched gas, various embodiments of the present invention are possible, such as obtaining nitrogen-enriched gas by replacing the adsorbent and using, for example, molecular sieve type carbon. Effects of the Invention The gas adsorption separation device of the present invention is constructed by stacking molded adsorbents so that the gas to be treated flows alternately through the internal flow path and the external flow path. Unlike when it is used, it can withstand changes in pressure and temperature and maintain its function over a long period of time. Even when the performance of the adsorbent deteriorates partially, it is easy to replace and regenerate only that part. As shown in the examples, the separation efficiency is excellent.
