Problems solved by technology
[0005] If the hydrogen cannot be discharged and accumulates, after mixing with the air, a hydrogen explosion may occur and damage the pressure vessel and the containment body. In severe cases, the long-term pollution to adjacent land is likely to far exceed that of a nuclear weapon explosion

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] Combine below Figure 1 to Figure 4 As shown, the present invention includes components with different heights and different catalytic capabilities. The height is determined according to the hydrogen concentration, and at the same time, considering the quadratic flow velocity distribution when the fluid flows in the pipeline, in order to reasonably arrange the catalysts, set components with strong catalytic capabilities. Placed at high flow rates, components with weaker catalytic capabilities are placed at low flow rates. and, Figure 1 to Figure 4 The different colors of the component units in are used to indicate the difference in catalytic ability.
[0028] figure 1 A hydrogen recombiner is shown, generally including a housing and internal catalytic components, although a limited number of components are shown, it should ...

The invention provides an optimization device of a hydrogen recombiner with an assembly structure. The device comprises a series of catalytic assembly units with different heights and different catalytic capabilities, and catalytic device bodies arranged in different areas according to a certain mode, wherein the catalytic assembly units are catalyst carriers for dehydrogenation reaction. The external geometric structures of the assembly units are the same in form, but the activity and the form of the catalyst filled in the assembly units are different, so that the reaction activity of the units as a whole is different; the catalytic device body is divided into a plurality of areas, and units with different reaction activities and different heights are selected in each area according to requirements, so that the reaction rate and the catalytic performance of the whole device are optimized. The assembly units are regularly arranged according to a certain mode to divide the whole catalytic device into a plurality of areas, and units with different reaction activities are selected according to the catalytic requirements of different areas, so that the reaction rate of the whole device is optimized.
Description
technical field [0001] The invention belongs to the technical field of hydrogen catalytic recombiners, discloses an optimization device for a hydrogen recombiner with component structure, and relates to an optimization device capable of efficiently eliminating hydrogen when a dehydration accident occurs in a nuclear reactor. Background technique [0002] An accident occurred at the Fukushima Daiichi Nuclear Power Plant in Japan. The accident was caused by an explosion caused by an earthquake and a nuclear leak. The accident was also rated as a level 6 nuclear accident. Among them, the accident caused the core to melt down, resulting in the leakage of radioactive materials, and at the same time, the nuclear fuel leaked due to the temperature being too high beyond the melting point of the zirconium-tin alloy of the fuel rod. [0003] When the temperature rises and the high-temperature water vapor formed after the water boils contacts with the zirconium-tin alloy, hydrogen gas ...
