Embodiment Construction
[0070] The technical solutions in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0071] It should be noted that all directional indications (such as up, down, left, right, front, back...) in this embodiment are only used to explain the relative relationship between the various components in a certain posture (as shown in the figure). If the positional relationship, movement conditions, etc., change the specific posture, the directional indication will also change accordingly.
[0072] In the present invention, unless otherwise specified and limited, the terms "connection" and "fixa...

The invention discloses a tail gas treatment system for a hydrogen-oxygen fuel cell, which comprises a gas buffer module, a hydrogen treatment module, a residual oxygen treatment module, a temperature control module, a safety early warning module and a PLC control module. Among them, the hydrogen treatment adopts a special microchannel reactor through non-fire combustion, and the remaining oxygen is treated through the reaction of relevant chemical reagents. The invention uses a gas mass flowmeter to control the flow rate of the reaction gas, and realizes the control of the reaction temperature of the microchannel reactor through the temperature control module. The invention can realize the real-time online operation temperature, exhaust gas concentration and exhaust gas pressure in the process of tail gas treatment. Monitor and regulate the flow and pressure of the exhaust gas, the temperature of the microchannel reactor, the temperature of the temperature control module and other functions. The present invention can automatically give an early warning for emergencies and failures, and is equipped with nitrogen one-key purge and emergency shutdown functions, which can effectively avoid unnecessary accidents caused by hydrogen leakage.
Description
technical field [0001] The invention belongs to the field of new energy and relates to a fuel cell technology, in particular to an exhaust gas treatment system for a hydrogen-oxygen fuel cell. Background technique [0002] A hydrogen-oxygen fuel cell is a power generation device that directly converts the chemical energy stored in hydrogen and oxygen into electricity in an efficient and green manner. Submarines powered by proton exchange membrane fuel cells have the characteristics of low noise, low infrared radiation, and zero pollution. Compared with submarines powered by nuclear power, they have the advantages of high safety and simple structure. In recent years, many domestic and foreign shipbuilders and research institutions have invested a lot of manpower, material and financial resources in the research and development, design and production of fuel cells for submarines. However, due to the characteristics of exhaust emissions, there are still many corresponding prob...
