Description

Technical Field

[0001] The invention relates to the technical field of natural gas reforming hydrogen production, and in particular to a natural gas reforming manufacturing device for hydrogen energy production. Background Art

[0002] As the global demand for clean energy continues to grow, hydrogen energy, as an efficient and clean energy form, is receiving more and more attention. There are various ways to produce hydrogen energy. Among them, natural gas reforming technology is widely used due to its abundant raw materials and mature processes. Natural gas reforming manufacturing equipment converts natural gas into a hydrogen-rich gas mixture through a series of chemical reactions, which is then used for the production and supply of hydrogen energy. Existing equipment often feeds natural gas into the reaction chamber of the equipment, which contains one or more reformers. Reformer tubes are usually set inside the reformer. Natural gas contacts with high-temperature catalysts in the reformer tubes to undergo reforming reactions. In this process, natural gas is decomposed into gases such as hydrogen, carbon monoxide and carbon dioxide. The converted gas is transported through pipelines, flows through coolers and adsorbers to filter impurities, and is finally compressed and collected. However, in the process of natural gas reforming, methane and water vapor react at high temperatures to generate carbon monoxide and hydrogen. However, if the reaction conditions are not appropriate, carbon deposits may be generated. In addition, at high temperatures, methane may also undergo cracking reactions to generate Carbon and hydrogen are important pathways for the formation of carbon deposits. Finally, during the reforming process, carbon monoxide may also undergo a disproportionation reaction to generate carbon deposits and carbon dioxide. This reaction is usually more likely to occur at lower temperatures. These carbon deposits will be deposited inside the conversion tube, especially on the surface of the catalyst. The formation of carbon deposits will not only reduce the activity of the catalyst, leading to a decrease in the efficiency of the reforming reaction, but may also clog the conversion tube, affecting the flow and mixing of the gas, further reducing the production efficiency of the equipment. Existing equipment often reduces the impact of carbon deposits by optimizing the selection of catalysts and adjusting operating conditions, but these methods do not reduce the impact of carbon deposits on the equipment.

[0023] The working principle of the natural gas reforming manufacturing equipment for hydrogen energy production provided by the present invention is as follows: Natural Gas Reforming: Start the igniter, and when the temperature in the reformer 2 reaches the required level, the natural gas, which is mainly composed of methane and water vapor, is sent into the reaction chamber 1. The natural gas and water vapor are preheated in the heat conduction chamber 8 and flow into the reformer 2. The reformer 2 is provided with three layers of reforming tubes 4. The natural gas passes through the reforming tubes 4 from top to bottom and undergoes reforming reaction under the action of the high-temperature catalyst. The main reactions include the methane steam reforming reaction CH 4 + H 2 O → CO + 3H 2 , methane cracking reaction CH 4 → C + 2H 2 and the carbon monoxide disproportionation reaction 2CO → C + CO 2 These reactions are carried out under high temperature, appropriate pressure and water-carbon ratio conditions to generate hydrogen, carbon monoxide, carbon dioxide and other gases. The reacted gas flows out from the bottom of the conversion tube 4 and flows into the heat exchange coil 10 in the water tank 9 through a pipeline to transfer heat to water. Then the gas flows into the cooler 12 through a pipeline. After the water vapor in the gas is removed, the gas flows into the adsorber 13 on the left through a pipeline. After the adsorber 13 adsorbs the impurities, hydrogen flows out from the top of the adsorber 13. Carbon deposit filtration: When the reaction gas passes through the middle-layer conversion tube 6, the gas passes through the gap between the upper cone plate 17 and the lower cone plate 21. The solid particles will be adsorbed on the side wall of the lower cone plate 21 during the rising process of the gas. The fan blade 19 drives the rotating ring 15 to rotate under the action of the airflow, and then drives the scraper 20 to rotate. The scraper 20 scrapes off the carbon deposits attached to the side wall of the lower cone plate 21 and drives the carbon deposits to move, so that the carbon deposits fall into the carbon storage box 25. When the gas passes through the filter plate 23, the carbon deposit particles carried by the gas will collide and adsorb with the irregular filter holes, reducing the amount of carbon deposits flowing into the lower cone plate 21, thereby avoiding catalyst poisoning. Replacement of catalyst and removal of carbon deposits: The handle 39 is pulled outward to rotate the sleeve 40 out of the L-shaped column 38, the locking of the plug column 37 is released, and the middle-level conversion tube 6 is rotated away from the limiting ring 36. Then, one hand supports the catalytic bed 24, and the other hand opens the multiple sets of protective sleeves 32 in turn and squeezes the first limiting column 31 on one side of the short plate 27 to release the locking of the second limiting column 33 by the first limiting column 31. The first limiting column 31 squeezes the spring 30 and rotates the long plate 29 out. The spring 30 squeezes the first limiting column 31 to reset, and the carbon storage box 25 is taken out from the circular support plate 26. The hand supporting the catalytic bed 24 moves downward. The catalytic bed 24, the lower cone plate 21 and the filter plate 23 will move downward synchronously due to their own gravity. The catalytic bed 24, the lower cone plate 21 and the filter plate 23 are taken out of the middle-level conversion tube 6, and the carbon storage box 25, the catalytic bed 24, the lower cone plate 21 and the filter plate 23 are processed accordingly and then put back according to the above reverse steps.
