Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen purification, in particular to an automatic purification device for hydrogen preparation. Background Art

[0002] Hydrogen has the advantages of high calorific value and pollution-free combustion. It is an ideal fuel gas. The development and utilization of hydrogen can effectively solve energy problems. However, in the process of hydrogen preparation, hydrogen needs to undergo a series of purification.

[0003] There are many hydrogen purification technologies in the prior art, among which pressure swing adsorption is a common one. It mainly provides silica gel and activated alumina layers at the air inlet of the adsorption tower to intercept easily adsorbed components such as water vapor, carbon dioxide and macromolecular hydrocarbons, and plays the role of a pretreatment bed. A molecular sieve layer is provided at the air outlet end to ensure the purity of the product hydrogen, and an activated carbon layer is provided in the middle. During purification, the compressed gas mixture is passed into the adsorption tower, and the adsorbent selectively adsorbs hydrogen, while other gases are excluded. The pressure of the adsorption tower is reduced, and the adsorbent releases the adsorbed hydrogen, thereby achieving the purification of hydrogen.

[0004] However, there are great troubles in replacing the adsorbent. Every time, it is necessary to use equipment to reach the designated maintenance port. However, when using the equipment to shovel out and clean the adsorbent, debris will inevitably fall down during this cleaning, which will affect the adsorbent in the lower layer. At the same time, when adding adsorbent, the same situation occurs. You can only choose to fill the upper layer first and then clean the lower layer, which is very troublesome.

[0005] Therefore, we proposed an automatic purification device for hydrogen preparation that does not affect the normal flow of gas and is easy to clean and replace the adsorbent to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic purification device for preparing hydrogen to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 5 In this embodiment, an automatic purification device for preparing hydrogen includes an adsorption purification tower 1, one side of the adsorption purification tower 1 is evenly penetrated and fixedly connected with an inspection port 2, the interior of the adsorption purification tower 1 is evenly fixedly connected with a lower fixed seat 6, the top of the lower fixed seat 6 is provided with a cloth cover 4, the bottom end of the cloth cover 4 is tilted and fixedly connected with a discharge pipe 14, the inner surface of the adsorption purification tower 1 above the lower fixed seat 6 is correspondingly fixedly connected with an upper fixed seat 8, the top of the upper fixed seat 8 is fixedly connected with a filter bucket 5, the bottom end of the filter bucket 5 is slidably connected with a filter cartridge 9, the bottom end of the filter cartridge 9 is hinged with a filter cover 10, and the interior of the adsorption purification tower 1 above the filter bucket 5 is slidably connected with a filter screen 3.

[0027] like Figure 2 In this embodiment, a molecular sieve layer is arranged between the filter screen 3 and the filter bucket 5 at the lower end of the adsorption purification tower 1, an activated carbon layer is filled between the filter screen 3 and the filter bucket 5 in the middle of the adsorption purification tower 1, and silica gel and activated alumina layers are filled inside the filter screen 3 and the filter bucket 5 at the upper end of the adsorption purification tower 1. The silica gel and activated alumina layers are used to intercept easily adsorbable components such as water vapor, carbon dioxide and macromolecular hydrocarbons, and play the role of a pretreatment bed. The activated carbon layer is used for further adsorption treatment, and the purity of the product hydrogen is ensured by the molecular sieve layer. When the pressure of the adsorption tower is reduced, the adsorbent releases the adsorbed hydrogen, and the automatic purification of the hydrogen can be achieved.

[0028] like Figure 2, Figure 3 and Figure 5 In this embodiment, the top of the cloth cover 4 is evenly fixedly connected with an annular plate 7. By arranging multiple annular plates 7, it is convenient to send the annular plates 7 into the adsorption purification tower 1. The annular plate 7 is fixedly connected to the lower fixing seat 6 by bolts, so that the cloth cover 4 can be unfolded and fixed.

[0029] like Figure 2 , Figure 3 and Figure 5 The cloth cover 4 in this embodiment is in the shape of a funnel to facilitate the diversion of the adsorbent material or debris, and the bottom end of the discharge pipe 14 extends into the interior of the inspection port 2 to facilitate the diversion of the adsorbent material or debris to the outside.

[0030] like Figure 2 and Figure 4 In this embodiment, the inner diameter of the bottom end of the filter bucket 5 is equal to the outer diameter of the filter cartridge 9, and the top end of the filter cartridge 9 is flush with the bottom end of the filter bucket 5 to avoid affecting the adsorbent material, so that the gas can flow evenly.

[0031] like Figure 2 The inspection port 2 in this embodiment is located between the filter screen 3 and the cloth cover 4, so as to facilitate filling or removing the adsorbent material, and also to facilitate fixing and installing the cloth cover 4.

[0032] like Figure 4 In this embodiment, a pull rope 11 is fixedly connected to one side of the bottom end of the filter cover 10, and one end of the pull rope 11 is fixedly connected to a fixing ring 13.

[0033] It can be understood that the automatic purification device for hydrogen preparation can receive the adsorbent material or debris through the cloth cover 4, so that the adsorbent material can be quickly discharged, while reducing the trouble of subsequent debris cleaning, thereby greatly facilitating the replacement and addition of the adsorbent material.

[0034] The complete usage steps and working principle of the utility model are as follows:

[0035] First, the compressed mixed gas is introduced into the adsorption purification tower 1, and the easily adsorbed components such as water vapor, carbon dioxide and macromolecular hydrocarbons are intercepted through the silica gel and activated alumina layers, which play the role of a pretreatment bed. The activated carbon layer is further used for adsorption treatment, and the purity of the product hydrogen is ensured by the molecular sieve layer. When the pressure of the adsorption tower is reduced, the adsorbent releases the adsorbed hydrogen, and the automatic purification of hydrogen can be achieved;

[0036] When the adsorbent needs to be replaced, the staff can enter the adsorption purification tower 1 through the inspection port 2, and then loosen the fixing bolts 12 to cancel the fixing of the fixing ring 13, so that the filter cover 10 can be unfixed and turned downward, so that the adsorbent on the filter bucket 5 falls through the filter cartridge 9, thereby realizing the rapid discharge of the adsorbent and avoiding the trouble of shoveling out or negative pressure suction;

[0037] Before unloading, the cloth cover 4 can be inserted into the adsorption purification tower 1, and the annular plate 7 can be fixed on the lower fixed seat 6 to unfold the cloth cover 4 for installation, and one end of the discharge pipe 14 can be extended out of the inspection port 2. The adsorbent material can be received and output through the cloth cover 4, and the debris can also be collected and discharged during loading, thereby finally realizing the rapid output of the adsorbent material and avoiding the trouble of cleaning the loading debris.

[0038] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
