Description

Technical Field

[0001] This utility model belongs to the field of PEM electrolysis for hydrogen production, specifically relating to a box-type hydrogen toxicity treatment device. Background Technology

[0002] Hydrogen energy, as a zero-carbon energy carrier, is increasingly demonstrating its core value in areas such as power system peak shaving, transportation power substitution, and industrial decarbonization. As the source equipment in the hydrogen energy industry chain, the technological level of hydrogen generators directly determines the cost, purity, and carbon emission safety of hydrogen.

[0003] Hydrogen gas has physical properties such as small molecular size, high permeability, and fast diffusion speed, which makes it easier for it to seep out from gaps, sealing surfaces, or micropores in materials inside equipment than other gases. This makes hydrogen generators potentially prone to leakage. Currently, to prevent internal hydrogen leakage, hydrogen leak detectors are often installed inside the generator to issue an alarm when a leak occurs. However, if the generator is not shut down in time, these leak detection methods can still pose a safety threat.

[0004] In view of this, based on the above-mentioned means, this utility model provides a box-type hydrogen hazard treatment device, which is used to catalytically oxidize hydrogen in the event of hydrogen leakage, thereby effectively reducing the possibility of hydrogen hazard.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model relates to a box-type hydrogen toxicity treatment device, such as... Figures 1-4 As shown, the device includes a housing 11 and a suction module 12 disposed opposite to the housing 11 to create convection between the inside and outside of the housing 11. The suction module 12 is, for example, an exhaust fan or a blower, and is connected to the control system of the hydrogen generator. In this embodiment, preferably, the suction module 12 is a blower. Inside the housing 11, along its convection direction, are sequentially arranged a filter section for filtering air, a catalyst section 15 for catalytically oxidizing hydrogen, and a guide section 16 for collecting catalytic reactants.

[0025] Among them, such as Figures 3-4 As shown, the filtration section includes a first filter layer 13 and a second filter layer 14, the catalytic section 15 includes a honeycomb ceramic, an active coating covering the inner wall of the honeycomb ceramic pores, and a palladium catalyst dispersed and embedded in the active coating, and the flow guide section 16 includes a water collection box 161 that is attached to the flow end of the catalytic section 15.

[0026] Specifically, in this embodiment, the first filter layer 13 is made of multi-layered stainless steel sintered felt, used to intercept solid particulate impurities of different sizes in the gas drawn by the suction module 12; the second filter layer 14 includes a breathable bag 141 and an adsorption layer 142 disposed within the breathable bag 141. The breathable bag 141 is a common breathable bag, and the adsorption layer 142 is boron nitride modified carbon nanotube powder wrapped inside the breathable bag. After the drawn gas passes through the first filter layer 13, it can be further adsorbed and filtered by the second filter layer 14.

[0027] Furthermore, the active coating is an Al2O3 coating, which has a high specific surface area. By coating it on the inner wall of the honeycomb ceramic pores, the smooth inner wall of the honeycomb ceramic pores can be transformed into a "nanoscale rough" surface, so that the subsequently loaded palladium catalyst can be highly dispersed. The palladium catalyst can catalyze the reaction of hydrogen and oxygen to produce water at room temperature.

[0028] Furthermore, the flow guide 16 includes a water collection box 161 that is attached to the flow end of the catalyst section 15. When hydrogen reacts with oxygen in the catalyst section 15 to produce water, it will flow into the water collection box 161 through the pores of the honeycomb ceramic for collection. The heat generated by the reaction is discharged to the outside of the hydrogen production equipment through the suction module 12 at the flow end.

[0029] Preferably, a drain hole 162 for connecting to the water tank of the hydrogen production equipment can be provided inside the water collection box 161. The drain hole 162 extends out of the box body 11 so that the collected water can be discharged into the water tank of the hydrogen production equipment for collection and reuse. At the same time, in order to facilitate the flow of water into the drain hole 162, the inner wall of the water collection box 161 is set as an inclined surface. The inclined surface gradually shrinks from the edge of the water collection box 161 towards the drain hole 162 so that when the reaction water enters the water collection box 161, it can be quickly discharged from the drain hole 162 through the guidance of its inner wall.

[0030] In use, the device is installed inside the hydrogen generator. The drain hole 162 at the bottom of the housing 11 is connected to the water tank inside the hydrogen generator through a pipe. When the hydrogen leak detector inside the hydrogen generator sounds an alarm, the control system of the hydrogen generator can control the suction module 12 to operate, so that it can suck up the leaked hydrogen inside the hydrogen generator. After being sucked by the suction module 12, the hydrogen enters the housing 11 and passes through the first filter layer 13, the second filter layer 14 and the catalyst section 15 in sequence to generate water, which flows into the water collection box 161. Excess gas is discharged to the outside of the hydrogen generator through the suction module 12 at the end of the flow. The water produced by the reaction is guided by the inner wall of the water collection box 161, so that the water enters the drain hole 162 and flows into the water tank inside the hydrogen generator for collection and reuse.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
