Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen purification, in particular to an integrated station device for purifying high-purity hydrogen from hydrogen-containing gas and hydrogenation. Background Art

[0002] Hydrogen is an environmentally friendly energy source. It only produces water during its combustion and releases energy, achieving pollution-free conditions. Therefore, people have begun to strengthen their research on hydrogen. During the preparation process, hydrogen contains other impurities such as water vapor. Generally, hydrogen needs to be purified before use to ensure the purity of the hydrogen discharged from the hydrogenation integrated station. However, the existing hydrogenation integrated station still has certain defects in use, such as:

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0031] Embodiment 1: This embodiment Figure 1-Figure 2 As shown, in order to solve the problem that there is no hydrogen purification in the process of gasification in the integrated device, a process of purifying high-purity hydrogen from hydrogen-containing gas and purifying hydrogen by an integrated hydrogenation station device is disclosed, which achieves the effect of improving the purity of the hydrogen. The specific contents are as follows:

[0032] A device body 1 and an air inlet pipe 2 and an air outlet pipe 3 fixedly installed outside the device body 1;

[0033] A barrier layer 4 is fixedly installed inside the device body 1, and a first one-way valve 5 is fixedly installed inside the barrier layer 4, a heater 6 is fixedly installed on the right side of the device body 1, and a heating tube 7 is fixedly installed on the side of the heater 6 located inside the device body 1, a second one-way valve 8 and a pressure relief valve 9 are fixedly installed on the side of the device body 1 close to the intake pipe 2, and the second one-way valve 8 is located inside the intake pipe 2, and an activated carbon plate 10 is slidably installed inside the intake pipe 2, and an adsorption plate 11 is snap-fitted inside the left side of the device body 1.

[0034] When using the integrated station device for purifying high-purity hydrogen and hydrogenation from hydrogen-containing gas, first place the device at the position where it needs to work. After placing the device at the required position, the integrated station can transport hydrogen. In this process, low-temperature hydrogen needs to be first injected into the interior of the device body 1 through the intake pipe 2 (hydrogen low temperature is a prior art and does not need to be further explained). In this process, hydrogen will pass through the activated carbon plate 10 inside the intake pipe 2. At this time, the activated carbon plate 10 will absorb the water vapor in the hydrogen, and then the hydrogen will enter through the second one-way valve 8. The hydrogen enters the right side of the barrier layer 4, and the heater 6 heats the heating tube 7. At this time, the heated heating tube 7 contacts with the water vapor at low temperature, which condenses the water vapor into water droplets outside the heating tube 7, thereby separating it from the hydrogen and ensuring the dryness of the hydrogen. After that, the hydrogen passes through the barrier layer 4 through the first one-way valve 5 and enters the left side of the device body 1. At this time, the hydrogen will pass through the adsorption plate 11 to adsorb the impurities contained therein again, and finally the hydrogen will be discharged through the outlet pipe 3 to obtain pure hydrogen, thereby completing the hydrogen purification process of the device.

[0035] Embodiment 2: This embodiment is as follows Figure 1-Figure 4 As shown, in order to solve the problem that the activated carbon plate 10 cannot be replaced in time during use, a process in which the activated carbon plate 10 in the intake pipe 2 can be replaced in time is disclosed, so that the adsorption effect of the activated carbon plate 10 can be guaranteed during the use of hydrogen. The specific contents are as follows:

[0036] A prompting structure is provided inside the air intake pipe 2, and the prompting structure realizes the effect of prompting to replace the activated carbon plate 10 by changing the sliding position of the sliding rod 15;

[0037] A support spring 12 and a contact plate 13 are provided inside the prompt structure. The contact plate 13 is slidably mounted on the upper end of the activated carbon plate 10, and the support spring 12 is fixedly mounted on one end of the contact plate 13 close to the activated carbon plate 10, and the upper end of the contact plate 13 is always in contact with the inner surface of the upper end of the intake pipe 2;

[0038] Three groups of activated carbon plates 10 and adsorption plates 11 are arranged inside the air intake pipe 2, and a support plate 14 is mounted on the lower end of the activated carbon plate 10, and a sliding rod 15 is fixedly mounted on the lower end of the support plate 14, and the sliding rod 15 is slidably connected to the air intake pipe 2;

[0039] A return spring 16 is sleeved on the outer side of the sliding rod 15 and is located inside the intake pipe 2 . Two sets of fixing plates 17 are fixedly installed inside the intake pipe 2 and the fixing plates 17 are slidably connected to the left and right ends of the support plate 14 .

[0040] When the integrated station device for purifying high-purity hydrogen and hydrogenation from hydrogen-containing gas is used, hydrogen passes through the activated carbon plate 10 through the air inlet pipe 2 and the water vapor therein is adsorbed by the activated carbon plate 10. After the activated carbon plate 10 absorbs the water vapor in the hydrogen, the weight of the activated carbon plate 10 itself will increase. After the internal water vapor of the activated carbon plate 10 reaches a certain content, it cannot continue to absorb the water vapor in the hydrogen. Then the activated carbon plate 10 needs to be replaced. When the water content inside the activated carbon plate 10 increases, the weight of the activated carbon plate 10 will increase and expand the pressure on the support plate 14. At this time, the pressure of the support plate 14 on the return spring 16 can be enhanced. At this time, the activated carbon plate 10 and the support plate 14 can make the sliding rod 15 slide downward. In this process, the return spring 16 will be squeezed and contracted. At this time, the downward sliding distance of the sliding rod 15 can be observed through the scale line on the outside of the sliding rod 15, so as to judge the adsorption capacity of the activated carbon plate 10 at this time, and the activated carbon plate 10 can be replaced in time.

[0041] During the downward movement of the activated carbon plate 10, the contracted support spring 12 will expand and push the contact plate 13 to move upward, and the contact plate 13 will always be in contact with the upper inner surface of the intake pipe 2 during the upward movement, so that the contact plate 13 and the activated carbon plate 10 can seal the interior of the intake pipe 2, preventing hydrogen from directly entering the interior of the device body 1 through the intake pipe 2.

[0042] Embodiment 3: This embodiment is as follows Figure 1-Figure 2 and Figure 5-Figure 6 As shown, in order to solve the problem that the condensed water flow inside the device body 1 cannot be discharged, the process of purifying high-purity hydrogen from hydrogen-containing gas and discharging the water flow inside the hydrogenation integrated station device is disclosed, and the effect of the device completely purifying hydrogen is achieved. The specific contents are as follows:

[0043] A drainage structure is provided inside the right side of the device body 1, and the drainage structure can discharge the water dripping from the heating tube 7 into the device body 1;

[0044] A drainage groove 18 is provided inside the lower end of the device body 1, and the drainage groove 18 is located on the right side of the barrier layer 4, and a sealing member 19 is slidably installed inside the drainage groove 18, and a connecting spring 24 is fixedly installed on one side of the sealing member 19 close to the device body 1;

[0045] A support frame 22 is provided inside the drainage structure, and the support frame 22 is fixedly installed on the outside of the device body 1, and the inner thread of the support frame 22 is connected to the threaded rod 21, and the outer side of the threaded rod 21 is slidably connected to the support rod 20, and the upper end of the support rod 20 is located inside the sealing member 19;

[0046] Two sets of drainage holes 23 are formed inside the device body 1 , and the drainage holes 23 are located inside the drainage groove 18 .

[0047] When using the integrated station device for purifying high-purity hydrogen and hydrogenation from hydrogen-containing gas, during the process of replacing the activated carbon plate 10, the water flow gathered in the drainage groove 18 can be discharged. In this process, the threaded rod 21 needs to be rotated. During the rotation of the threaded rod 21, it will move upward inside the support frame 22, and during the upward movement of the support frame 22, it will push the support rod 20 to move upward, and the upward movement of the support rod 20 will cause the seal 19 to move upward synchronously. The upward movement of the seal 19 will open with the drainage groove 18 and the drainage hole 23, and then the water flow gathered in the device body 1 will be discharged through the drainage hole 23, and during the upward movement of the seal 19, the connecting spring 24 will expand. Similarly, the reverse rotation of the threaded rod 21 can make the seal 19 seal with the drainage groove 18 again. By discharging the water flow, the drying effect of the device on hydrogen is effectively guaranteed, thereby increasing the overall practicality.

[0048] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
