Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen adsorption, in particular to a hydrogen adsorption tower regeneration device. Background Art

[0002] Hydrogen is a flammable and explosive gas. It is colorless, odorless and non-toxic at atmospheric pressure and room temperature. It has a very low boiling point (20.4K) and is non-corrosive. However, at high temperatures (>260°C), it will corrode certain metals, such as carbon steel, and react with the carbon in the metal to produce "hydrogen embrittlement". Hydrogen is the lightest of all elements, with a molecular weight of 2, a specific gravity to air of 0.07 (the specific gravity of air is 1), and a density of 0.09 kg / m 3 , it also has a high degree of permeability. Hydrogen cannot be used for breathing, so it can suffocate people at high concentrations. The auto-ignition point of hydrogen is 560°C.

[0003] The hydrogen adsorption tower is used to adsorb the organic phase of methyl ethyl ketone and sec-butyl alcohol entrained in hydrogen. However, when a single hydrogen adsorption tower is operated for a long time, the adsorption capacity of the adsorbent will decrease, affecting the quality of the adsorbent. Therefore, when the adsorbent is saturated, the hydrogen adsorption tower must be cut out for regeneration, otherwise the quality of the hydrogen product will be affected. Therefore, it is necessary to provide a hydrogen adsorption tower regeneration device to achieve the regeneration of the hydrogen adsorption tower. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a hydrogen adsorption tower regeneration device. When the hydrogen adsorption tower is regenerated, the hydrogen adsorption tower is first depressurized, and then the organic phase in the hydrogen adsorption tower is analyzed by water vapor. At the same time, the analyzed regenerated materials are recovered and reused through a material recovery unit, and then the hydrogen adsorption tower is purged with hot nitrogen and cold nitrogen in turn. Finally, the hydrogen adsorption tower is balanced with hydrogen by using qualified hydrogen, so that the regeneration of the hydrogen adsorption tower can be completed, and the stable operation of hydrogen adsorption is guaranteed.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown, the present embodiment provides a hydrogen adsorption tower regeneration device, comprising a hydrogen adsorption tower A1 and a hydrogen adsorption tower B2 connected in series, the hydrogen feed ports of the hydrogen adsorption tower A1 and the hydrogen adsorption tower B2 are respectively connected to a hydrogen feed pipeline 101 and a hydrogen feed pipeline 201, and a feed valve 102 and a feed valve 202 are respectively provided on the hydrogen feed pipeline 101 and the hydrogen feed pipeline 201, when hydrogen is subjected to organic phase adsorption, the feed valve 102 can be opened and the feed valve 202 can be closed, so that the hydrogen first enters the hydrogen adsorption tower A1 for adsorption, and then enters the hydrogen adsorption tower B2 for adsorption, and finally produces qualified hydrogen; conversely, the feed valve 202 can be opened and the feed valve 102 can be closed, so that the hydrogen first enters the hydrogen adsorption tower B2 for adsorption, and then enters the hydrogen adsorption tower A1 for adsorption, and finally produces qualified hydrogen.

[0024] like Figure 1As shown, the hydrogen outlets of the hydrogen adsorption tower A1 and the hydrogen adsorption tower B2 are respectively connected to the hydrogen outlet pipeline 103 and the hydrogen outlet pipeline 203, the hydrogen outlet pipeline 103 and the hydrogen outlet pipeline 203 are both connected to the main pipeline 7, the main pipeline 7 is connected to the hydrogen feed ports of the hydrogen adsorption tower A1 and the hydrogen adsorption tower B2 through the branch line 109 and the branch line 209, the hydrogen outlet pipeline 103 and the hydrogen outlet pipeline 203 are respectively connected to the hydrogen feed ports of the hydrogen adsorption tower A1 and the hydrogen adsorption tower B2. A discharge valve 104 and a discharge valve 204 are respectively provided on the branch line 109 and the branch line 209 are respectively provided with a discharge valve 3 110 and a discharge valve 4 210; the hydrogen discharge ports of the hydrogen adsorption tower A1 and the hydrogen adsorption tower B2 are also respectively connected to the product discharge pipeline 105 and the product discharge pipeline 2 205, and the product discharge pipeline 105 and the product discharge pipeline 2 205 are respectively provided with a discharge valve 106 and a discharge valve 2 206. The hydrogen adsorption tower A1 is connected in series with the hydrogen adsorption tower B2 through the hydrogen discharge pipeline 103, the main pipeline 7 and the branch pipeline 109, and the hydrogen adsorption tower B2 is connected in series with the hydrogen adsorption tower A1 through the hydrogen discharge pipeline 203, the main pipeline 7 and the branch pipeline 209, so that the hydrogen enters the two adsorption towers successively for organic phase adsorption, and the generated qualified hydrogen is discharged to the outside through the product discharge pipeline 105 or the product discharge pipeline 205.

[0025] A sampling point S is set between the two adsorption towers. When the quality of the S analysis sample decreases, it means that the adsorbent in the adsorption tower before the sampling point is saturated and the adsorption tower needs to be cut out and regenerated in time. Figure 1 As shown, the hydrogen feed ports of hydrogen adsorption tower A1 and hydrogen adsorption tower B2 are connected to pressure relief pipeline 1 107 and pressure relief pipeline 2 207 respectively, and pressure relief valve 1 108 and pressure relief valve 2 208 are respectively arranged on pressure relief pipeline 1 107 and pressure relief pipeline 2 207, and pressure relief pipeline 1 107 and pressure relief pipeline 2 207 are both connected to the condensing unit, and the condensing unit is connected to the venting pipeline 501, and the venting pipeline 501 is provided with a venting valve 502, and the liquid phase outlet of the condensing unit is connected to the material recovery unit through a pipeline. Taking the example that hydrogen first enters hydrogen adsorption tower A1 and then enters hydrogen adsorption tower B2, when the quality of S analysis sample decreases, it means that the adsorbent in hydrogen adsorption tower A1 before the sampling point is saturated and needs to be cut out and regenerated in time. At this time, you need to open the feed valve 202 first, close the feed valve 102 and the discharge valve 3 110, and the hydrogen only enters the hydrogen adsorption tower B2 for adsorption; open the pressure relief valve 108 and the vent valve 502, open the pressure relief pipeline 107, and relieve the pressure of the hydrogen adsorption tower A1 to 15KPa.

[0026] At the same time, in this embodiment, if Figure 1As shown, the hydrogen discharge pipeline 203 is connected to the steam feed pipeline 401, and the steam feed pipeline 401 is provided with a steam valve 402. After the pressure relief of the hydrogen adsorption tower A1 is completed, the steam valve 402 is opened, and the water vapor enters the top of the hydrogen adsorption tower A1 through the hydrogen discharge pipeline 203 and the hydrogen discharge pipeline 103 in sequence, and the organic phase in the hydrogen adsorption tower A1 is analyzed. When the temperature of the hydrogen adsorption tower A1 gradually increases, the organic phase is gradually analyzed, and the regenerated material enters the condensation unit through the pressure relief pipeline 107 for condensation. The gas phase generated during the condensation process is discharged, and the condensed liquid phase (methyl ethyl ketone, sec-butyl alcohol) enters the material recovery unit for recovery.

[0027] Specifically, in this embodiment, Figure 1 As shown, the condensing unit includes condenser 1 503 and condenser 2 504, the venting line 501 is connected to condenser 2 504, the pressure relief line 107 and the pressure relief line 207 are both connected to the feed port of condenser 1 503, the gas phase discharge port of condenser 1 503 is connected to the feed port of condenser 2 504 through a pipeline, and the liquid phase discharge ports of condenser 1 503 and condenser 2 504 are respectively connected to the material recovery unit through pipelines. Among them, the tube side of condenser 1 503 is connected with a circulating water feed pipeline 5031 and a circulating water discharge pipeline 5032, and the tube side of condenser 2 504 is connected with a brine feed pipeline 5041 and a brine discharge pipeline 5042. The regenerated material from hydrogen adsorption tower A1 through pressure relief line 107 enters condenser 1 503 and condenser 2 504 successively for condensation, and the liquid phases produced by the two condensers enter the material recovery unit.

[0028] Among them, Figure 1 As shown, the material recovery unit includes a material buffer tank 601, the liquid phase outlets of condenser 1 503 and condenser 2 504 are connected to the feed port of the material buffer tank 601 through a pipeline, and the gas phase outlet of the material buffer tank 601 is connected to the feed port of condenser 2 504 through a pipeline; the liquid phase outlet of the material buffer tank 601 is connected to the feed port of the material storage tank 602 through a pipeline, and the outlet of the material storage tank 602 is connected to the feed port of the recovery tank 603 through a pipeline, and the recovery tank 603 is connected to a methyl ethyl ketone outlet pipeline 6031 and a jacket is arranged outside the recovery tank 603, and the jacket is connected to a steam heating feed pipeline and a steam heating discharge pipeline, and low-pressure steam is passed into the steam heating feed pipeline.

[0029] After the regenerated material is condensed by condenser 1 503 and condenser 2 504, the generated liquid phase enters the material buffer tank 601, and the gas phase of the logistics buffer tank enters condenser 2 504 for further condensation. The regenerated material in the material buffer tank 601 then enters the material storage tank 602 and the recovery tank 603 in sequence. Among them, a nitrogen charging pipeline can be connected to the material storage tank 602 to pressurize the material storage tank 602 to 0.3MPa, ensuring that the material can smoothly pass through the pipeline into the recovery tank 603. Under the heating of low-pressure steam in the jacket of the recovery tank 603, the methyl ethyl ketone in the material is sent to the methyl ethyl ketone refining section through the methyl ethyl ketone discharge pipeline 6031.

[0030] In addition, if Figure 1 As shown, the hydrogen discharge pipeline 103 and the hydrogen discharge pipeline 203 are both connected to the nitrogen feed pipeline 301, the nitrogen feed pipeline 301 is connected to the heat exchanger 3, the heat exchanger 3 is connected to the nitrogen pipeline 304, and the pipe side of the heat exchanger 3 is connected to the heat transfer oil feed pipeline 302 and the heat transfer oil discharge pipeline 303. The material in the material buffer tank 601 is analyzed. When the water content is less than 99%, the steam valve 402 is closed and the steam is stopped from being passed to the hydrogen adsorption tower A1. Then, the heat transfer oil is passed to the pipe side of the heat exchanger 3 to preheat the nitrogen, and the nitrogen amount is controlled to be 100 kg / m 3 , the heated nitrogen enters the hydrogen adsorption tower A1 through the nitrogen feed pipeline 301, the pressure of the hydrogen adsorption tower A1 is controlled to be 2-5 kPa, the water vapor in the hydrogen adsorption tower A1 is purged, and the purged nitrogen enters the condenser 1 503 and the condenser 2 504 through the pressure relief pipeline 107, and then is vented through the vent pipeline 501. When the hydrogen adsorption tower A1 is free of water vapor, the heat transfer oil is stopped from being passed into the heat exchanger 3, and cold nitrogen is passed into the hydrogen adsorption tower A1 for purging and cooling.

[0031] Subsequently, the discharge valve 104, the pressure relief valve 108 and the vent valve 502 are closed, and the discharge valve 106 is opened to introduce the qualified hydrogen from the hydrogen adsorption tower B2 into the hydrogen adsorption tower A1 to replace the nitrogen in the regenerated hydrogen adsorption tower A1, and to balance the hydrogen. After each hydrogen is introduced into the hydrogen adsorption tower A1 to make the pressure of the hydrogen adsorption tower A1 reach the working pressure, the pressure relief valve 108 and the vent valve 502 are opened to release the pressure. After three times, the temperature of the hydrogen adsorption tower A1 drops to about 5°C, and it can be connected to the adsorption process. At this time, the discharge valve 204, the discharge valve 3 110 and the discharge valve 106 are opened, and the discharge valve 206 is closed to achieve that the hydrogen enters the hydrogen adsorption tower B2 first and then enters the hydrogen adsorption tower A1, thereby entering the next adsorption cycle.
