Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen removal tanks, in particular to a hydrogen removal tank. Background Art

[0002] Hydrogen is a highly flammable and explosive gas that easily accumulates, especially in closed environments. When it reaches a certain concentration, it may cause an explosion. Therefore, in the production process of petrochemical, metallurgical and other industries, timely and effective removal of hydrogen from the environment to ensure workplace safety has become an important technical requirement.

[0003] An existing hydrogen removal tank and ballast water treatment system with the same (Announcement No.: CN205023893U) have at least the following disadvantages: the above-mentioned device electrolyzes to separate hydrogen from seawater, and then discharges the hydrogen mixed with air through an explosion-proof blower. However, the hydrogen removal tank cannot effectively remove hydrogen by directly discharging the hydrogen, and hydrogen is extremely prone to explosion after mixing with air. If the discharge is improper or sparks are encountered during the discharge process, an explosion accident may occur, resulting in poor performance of the hydrogen removal tank. For this reason, we propose this utility model. Utility Model Content

Then, hydrogen is injected into the tank through the air inlet pipe. The hydrogen reacts with the dehydrogenation agent. The activated copper oxide reacts with the hydrogen in a high-temperature environment to produce copper and water.

Through the setting of the hydrogen removal structure, the staff starts the heater 203 through the temperature controller 301 to raise the temperature inside the tank body 1 to 200°C. Then, hydrogen is injected into the tank body 1 through the air inlet pipe 2. The hydrogen reacts with the hydrogen removal agent 202, and the active copper oxide and hydrogen react in a high temperature environment. The reaction occurs in an environment to generate copper and water, and the water vaporizes in a high-temperature environment and is discharged from the outlet pipe 201.

The mesh partition 7 can isolate the dehydrogenating agent 202 from the outlet end of the air inlet pipe 2 to prevent the dehydrogenating agent 202 from clogging the air inlet pipe 2.

[0026] In this embodiment, the top end of the air inlet pipe 2 is connected to and fixed with a first diversion pipe 4, and the two air inlet ends of the first diversion pipe 4 are connected to and fixed with an air inlet valve 401. The two air inlet valves 401 are arranged up and down. When the staff inputs hydrogen into the tank body 1, the air inlet valve 401 located above can be opened. When inputting oxygen, the air inlet valve 401 located below can be opened, so that oxygen and hydrogen can enter the tank body 1 respectively through the first diversion pipe 4.

[0027] In this embodiment, the top end of the air outlet pipe 201 is connected to and fixed with a second diversion pipe 5, and the air outlet end of the second diversion pipe 5 is connected to and fixed with an exhaust valve 501. The exhaust valve 501 can control the discharge of water vapor to avoid excessive heat loss in the tank body 1.

[0028] In this embodiment, a mounting plate 6 is fixed to the bottom surface of the tank body 1, and connection holes 601 are opened at the four corners of the top surface of the mounting plate 6. Through the mounting plate 6 and the connection holes 601, the staff can install the tank body 1 at a designated position.

[0029] Working principle: During use, through the setting of the dehydrogenation structure, the staff starts the heater 203 through the temperature controller 301, raises the temperature in the tank body 1 to 200°C, and then injects hydrogen into the tank body 1 through the air inlet pipe 2. The hydrogen reacts with the dehydrogenation agent 202, and the active copper oxide reacts with the hydrogen in a high temperature environment to generate copper and water. The water vaporizes in a high temperature environment and is discharged from the air outlet pipe 201. No oxygen is required in the dehydrogenation process, and the gas does not need to contain oxygen, so dehydrogenation can be carried out. The dehydrogenation effect will not be affected by the amount of oxygen content, which ensures the use effect of the dehydrogenation tank. When the hydrogen removal is completed, the staff can inject oxygen into the tank body 1 through the air inlet pipe 2. The copper and The oxygen reaction produces active copper oxide, thereby activating and regenerating the active copper oxide after the complete reaction. The dehydrogenating agent 202 can be isolated from the outlet end of the air inlet pipe 2 by the mesh partition 7 to prevent the dehydrogenating agent 202 from clogging the air inlet pipe 2. When the staff inputs hydrogen into the tank body 1, the upper air inlet valve 401 can be opened. When inputting oxygen, the lower air inlet valve 401 can be opened to allow oxygen and hydrogen to enter the tank body 1 respectively through the first diversion pipe 4. The exhaust valve 501 can be used to control the discharge of water vapor to avoid excessive heat loss in the tank body 1. The staff can install the tank body 1 at the designated position through the mounting plate 6 and the connecting hole 601.
