Description

Technical Field

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

[0002] Hydrogen is a highly flammable, colorless, transparent, odorless and tasteless gas. Hydrogen is the smallest known gas in the world, with a density of only 1 / 14 of that of air, that is, at 0°C and a standard atmospheric pressure, the density of hydrogen is 0.0899g / L. When hydrogen is produced, it needs to be desulfurized in a desulfurization tank.

[0003] The utility model with application number 201920009784.2 discloses a desulfurization tank for hydrogen production, including a desulfurization tank body, an air inlet pipe inserted in the desulfurization tank body, and a desulfurization cavity is arranged in the desulfurization tank body, an air inlet cavity is arranged on the desulfurization cavity, and an air inlet hole connected with the desulfurization cavity is arranged on the air inlet cavity. The desulfurization tank for hydrogen production is provided with an independent desulfurization cavity in the desulfurization tank, and the air inlet pipe injects the hydrogen to be desulfurized into the air inlet cavity respectively, and the through holes on the air inlet cavity allow the hydrogen to enter the desulfurization cavity evenly. The second air outlet pipe can input the desulfurized hydrogen into the desulfurization cavity again for impact stirring to improve the hydrogen desulfurization efficiency.

[0004] However, hydrogen desulfurization generally uses a method of passing hydrogen through a desulfurization compound solvent. When sulfur-containing hydrogen is ejected from a nozzle immersed in the solution, bubbles are formed in the solution. The hydrogen in the bubbles cannot come into contact with the solution, resulting in the hydrogen being in the solution but unable to react with the solution immediately. Multiple cycles are required to completely desulfurize the hydrogen, thereby reducing the desulfurization efficiency of the hydrogen. Therefore, considering the quality of hydrogen preparation, multiple desulfurization cycles have to be carried out, which increases time and cost.

[0005] Therefore, based on the above problems, we propose a new type of desulfurization tank for hydrogen production. Utility Model Content

DETAILED DESCRIPTION

[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a new type of desulfurization tank for hydrogen production, including a desulfurization tank body 1, a desulfurization cavity 3 is arranged inside the desulfurization tank body 1, the interior of the desulfurization cavity 3 can provide a closed space for the desulfurization reaction of sulfur-containing hydrogen, an air inlet pipe 2 is fixedly connected to the surface of the desulfurization tank body 1, and sulfur-containing hydrogen can enter the interior of the desulfurization cavity 3 through the air inlet pipe 2, the interior of the air inlet pipe 2 and the interior of the desulfurization cavity 3 are interconnected, and a feed pipe 16 is fixedly connected to the upper surface of the desulfurization tank body 1, the feed pipe 16 passes through the surface of the desulfurization tank body 1 and is interconnected with the interior of the desulfurization cavity 3, and the desulfurization compound can be loaded into the interior of the desulfurization cavity 3 through the feed pipe 16.

[0027] A driving motor 4 is fixedly connected to the surface of the desulfurization tank body 1, and the output end of the driving motor 4 passes through the surface of the desulfurization tank body 1 and extends to the interior of the desulfurization cavity 3. The connection between the driving motor 4 and the surface of the desulfurization tank body 1 is set in a sealed state. The output end of the driving motor 4 is fixedly connected to a rotating shaft 5, and the rotating shaft 5 can rotate under the drive of the driving motor 4. The end of the rotating shaft 5 away from the driving motor 4 is rotatably connected to the inner bottom wall of the desulfurization cavity 3.

[0028] The surface of the rotating shaft 5 is slidably connected with a sliding cylinder 7, and two springs 9 are movably sleeved on the surface of the rotating shaft 5. The two ends of the two springs 9 are fixedly connected to the surface of the rotating shaft 5 and the inner wall of the sliding cylinder 7 respectively, and the spring 9 can restore the position of the sliding cylinder 7. The end of the sliding cylinder 7 away from the rotating shaft 5 is fixedly connected to a support rod 6, and the end of the support rod 6 away from the rotating shaft 5 is fixedly connected to a scraper 8. The side of the scraper 8 away from the support rod 6 is tightly attached to the inner wall of the desulfurization tank body 1, and the scraper 8 can scrape off the solid compounds attached to the inner wall of the desulfurization tank body 1. The surface of the sliding cylinder 7 is fixedly connected with a mesh plate 10, and the mesh plate 10 can move synchronously with the sliding of the sliding cylinder 7. The mesh plate 10 can move up and down step by step, and can rotate synchronously with the rotation of the mesh plate 10. The surface of the mesh plate 10 is provided with mesh holes 11, which are convenient for the smooth passage of hydrogen and the immersion of the mesh plate 10 in the desulfurization solution. The lower surface of the mesh plate 10 is fixedly connected with stirring blades 15 arranged evenly in a circle. When the rotating shaft 5 rotates, the rotation of the rotating shaft 5 can drive the sliding cylinder 7 to rotate synchronously. At this time, the rotation of the sliding cylinder 7 can also drive the mesh plate 10 to rotate synchronously. Similarly, when the mesh plate 10 rotates along with the sliding cylinder 7, it can drive the stirring blades 15 to rotate around the rotating shaft 5, thereby realizing the stirring of the desulfurization solution in the desulfurization cavity 3.

[0029] The inner wall of the desulfurization tank body 1 is fixedly connected with a protrusion 13, and the upper side of the protrusion 13 is set to be relatively inclined, so that the scraper 8 can pass smoothly on its surface. The surface of the desulfurization tank body 1 is fixedly connected with a reflux pipe 12, which runs through the surface of the desulfurization tank body 1 and is interconnected with the interior of the desulfurization cavity 3. The sulfur-containing hydrogen gas can reflux through the reflux pipe 12, thereby realizing the secondary desulfurization of the sulfur-containing hydrogen gas. The end of the reflux pipe 12 close to the bottom of the desulfurization tank body 1 is set in a U shape, which can make the sulfur-containing hydrogen gas more dispersed. The surface of the reflux pipe 12 is fixedly connected with air nozzles 14 arranged equidistantly. The cross-section of the air nozzle 14 is conical, which can increase the force of the ejected gas and facilitate the flow rate of the sulfur-containing hydrogen gas. The surface of the desulfurization tank body 1 is provided with air inlet holes 17 arranged equidistantly. The cross-section of the air inlet hole 17 is conical, and the interior of each air inlet hole 17 is interconnected with the interior of the air inlet pipe 2 and the interior of the desulfurization cavity 3.

[0030] Furthermore, when the device desulfurizes sulfur-containing hydrogen gas, the sulfur-containing hydrogen gas that enters the desulfurization cavity 3 through the air inlet pipe 2 and the air inlet hole 17 will enter the interior of the reflux pipe 12 after the first desulfurization, and then be ejected from the interior of the air nozzle 14 under the action of the air pump. At this time, the drive motor 4 is operated, and the output end of the drive motor 4 can rotate after operation. The rotation of the output end of the drive motor 4 will drive the rotating shaft 5 to rotate synchronously, and then the rotating shaft 5 can drive the sliding cylinder 7 to rotate synchronously while rotating. At this time, the sliding cylinder 7 can drive the grid plate 10 to rotate synchronously while rotating. Similarly, when the grid plate 10 rotates along with the sliding cylinder 7, it can drive all the stirring blades 15 to rotate around the rotating shaft 5 as the center, thereby realizing the stirring of the desulfurization solution in the desulfurization cavity 3. In this process, it can ensure that the reaction between the compounds in the solution and the catalyst is more sufficient, and drive the sulfur-containing hydrogen gas in the solution to move, thereby accelerating the desulfurization of the sulfur-containing hydrogen gas and saving time cost.

[0031] In addition, when the rotating shaft 5 drives the sliding cylinder 7 to rotate synchronously, the sliding cylinder 7 can drive the support rod 6 to rotate synchronously at the same time. At this time, the rotation of the support rod 6 can drive the scraper 8 to rotate synchronously, so that the scraper 8 can scrape off the solid compounds attached to the inner wall of the desulfurization tank body 1, and when the sliding cylinder 7 drives the scraper 8 to rotate to contact the inclined surface of the protrusion 13 on the inner wall of the desulfurization tank body 1, the surface of the scraper 8 will be squeezed by the inclined surface of the protrusion 13 on the inner wall of the desulfurization tank body 1 and move upward, thereby driving the sliding cylinder 7 to slide on the surface of the rotating shaft 5, and the sliding cylinder 7 can squeeze the spring 9 while sliding on the surface of the rotating shaft 5 so that the spring 9 has a certain elastic force, and then when the scraper 8 is separated from the protrusion 13 on the inner wall of the desulfurization tank body 1, the sliding cylinder 7 returns to its original position under the elastic force of the spring 9, and in this process, the scraper 8 can be shaken up and down, so that the solid compounds attached to the surface of the scraper 8 can be shaken off, and a large amount of solid compounds can be prevented from being attached to the surface of the scraper 8.

[0032] When the scraper 8 is squeezed by the inclined surface of the protrusion 13 and drives the sliding cylinder 7 to move on the surface of the rotating shaft 5, the movement of the sliding cylinder 7 can drive the mesh plate 10 to move synchronously, and then return to its original position under the elastic force of the spring 9. In this way, during the operation of the device, the mesh plate 10 can move up and down in the desulfurization solution. At this time, the mesh plate 10 can squeeze and chop the bubbles of sulfur-containing hydrogen in the solution during the movement, thereby avoiding the situation that the hydrogen is located in the bubbles and cannot react with the solution, allowing the sulfur-containing hydrogen to react more fully with the desulfurization solution, increasing the desulfurization amount of hydrogen in a single time, and then improving the desulfurization effect of sulfur-containing hydrogen, further accelerating the desulfurization speed of hydrogen preparation, reducing the number of desulfurization times, and saving resources and time costs.

[0033] Working principle: when the scraper 8 is squeezed by the inclined surface of the protrusion 13 and drives the sliding cylinder 7 to move on the surface of the rotating shaft 5, the movement of the sliding cylinder 7 can drive the mesh plate 10 to move synchronously, and then return to the original position under the elastic force of the spring 9. In this way, during the operation of the device, the mesh plate 10 can move up and down in the desulfurization solution. At this time, the mesh plate 10 can squeeze and chop the bubbles of sulfur-containing hydrogen in the solution during the movement, thereby avoiding the situation that the hydrogen is located in the bubbles and cannot react with the solution, so that the sulfur-containing hydrogen can react more fully with the desulfurization solution, increase the desulfurization amount of hydrogen in a single time, and then improve the desulfurization effect of sulfur-containing hydrogen, and further accelerate the desulfurization speed of hydrogen preparation.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
