[0001] This application relates to the field of hydrogen removal technology in closed environments, and in particular to a hydrogen removal device for closed environments. Background Technology
[0002] Hydrogen systems for underwater and confined environments are becoming increasingly common, such as hydrogen fuel cells used in underwater unmanned vehicles. These fuel cells employ various hydrogen supply methods, including liquid hydrogen storage, high-pressure hydrogen storage, metal hydrogen storage, methanol reforming for hydrogen production, and hydrogen production through the reaction of aluminum-based composite materials or compounds (such as sodium borohydride) with water.

Detailed Implementation
[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0041] In one exemplary embodiment, such as Figure 1 As shown, a hydrogen removal device for a closed environment is provided. The device includes an air inlet structure, a hydrogen removal structure, and a drying structure, wherein:
[0042] The air intake structure and the hydrogen elimination structure are connected in series, and the hydrogen elimination structure and the drying structure are connected in series.
[0043] The air intake structure includes a filter element, an air inlet, and an air intake frame. The air inlet is located on both sides of the frame, and the filter element is located in the air intake frame.
[0044] The air intake structure is used to draw in gas from a closed environment and transfer the gas to the hydrogen removal structure.
[0045] The hydrogen elimination structure includes a hydrogen concentration sensor, a first temperature sensor, an upwind section, and a downwind section. The upwind section includes a first explosion-proof fan and a first check valve, and the downwind section includes a second explosion-proof fan, a flame-arresting hydrogen elimination component, and a second check valve.
[0046] The hydrogen removal structure is used to remove hydrogen from the gas and then transfer the gas after hydrogen removal to the drying structure.
[0047] The drying structure includes a second temperature sensor, the drying structure itself, and a first air outlet.
[0048] The drying structure is used to dry and adsorb the gas after hydrogen removal treatment, and then discharge the gas after drying and adsorption treatment to a closed environment.
[0049] The air inlet's air intake direction is perpendicular to the air outlet's air outlet direction.
[0050] Optionally, the air inlet structure further includes a second air outlet, and the air inlet direction is perpendicular to the air outlet direction; the second air outlet is used to transmit the gas drawn in by the air inlet to the hydrogen elimination structure; the second air outlet is connected to the hydrogen concentration sensor of the hydrogen elimination structure.
[0051] In this embodiment, when the air inlet frame is a cubic structure, the air inlets are located at the front ends of the four sides of the air inlet frame. When the air inlet frame is a cylindrical structure, the air inlets are arranged around the front ends of the side curved surfaces of the air inlet frame. The air inlets can be in the shape of a complete rectangle, a mesh structure, or a fish-scale structure, etc. The design of the air inlet frame can be adjusted according to the size of the sealing environment and is not limited to a fixed style. The air inlets and the second air outlet are always perpendicular to each other.
[0052] Optionally, the air intake structure also includes: a detachable connection between the filter element and the air intake frame.
[0053] The detachable connection includes, but is not limited to, threaded connection, snap-fit connection, pin connection, and other connection methods.
[0054] Optionally, a hydrogen concentration sensor and a first temperature sensor are connected in series. The first temperature sensor is connected in series with both the upwind and downwind routes, and the upwind and downwind routes are connected in parallel. The hydrogen concentration sensor is wirelessly connected to both the first explosion-proof fan in the upwind route and the second explosion-proof fan in the downwind route. The hydrogen concentration sensor is used to control the start and stop status of the first and second explosion-proof fans. The first temperature sensor is used to monitor the pre-processing temperature of the gas and feed it back to the operator's client. The first explosion-proof fan is used to control the opening and closing of the upwind route, and the second explosion-proof fan is used to control the opening and closing of the downwind route. A first check valve is used to close the reverse flow of gas in the upwind route, and a second check valve is used to close the reverse flow of gas in the downwind route.
[0055] In this embodiment, the upwind path directly connects the air inlet to the second air outlet and also performs a sweeping drying process on the drying structure, thereby restoring the drying adsorption equipment in the drying structure to its original state. The downwind path performs catalytic combustion treatment on the intake gas, thereby reducing the hydrogen content in the intake gas.
[0056] Optional, such as Figure 2 As shown, the flame arrestor and hydrogen elimination component includes a flame arrester and a hydrogen elimination core, and the flame arrestor and hydrogen elimination component is connected in series with the second explosion-proof fan and the second check valve, respectively; the flame arrester is connected in series with the hydrogen elimination core; the hydrogen elimination core is used to eliminate hydrogen from the gas through catalytic combustion; the flame arrester is used to block the combustion state of the gas after the gas has completed the catalytic hydrogen elimination treatment and to transfer the gas to the second check valve.
[0057] Optionally, the second temperature sensor, the drying structure, and the first air outlet are connected in series. The second temperature sensor is used to monitor the temperature of the gas after hydrogen removal treatment and to feed back the temperature of the gas after hydrogen removal treatment to the operator's client. The drying structure is used to dry and adsorb the gas after hydrogen removal treatment and to discharge the dried and adsorbed gas to a closed environment through the first air outlet.
[0058] The drying structure includes adsorbent materials for adsorbing water vapor and moist liquids from the gas.
[0059] Optionally, the drying structure may also include: when the upwind path is open, the drying structure is in a purging and cleaning state; when the downwind path is open, the drying structure is in a drying and adsorption state.
[0060] In this embodiment, during actual operation, only one of the upwind and downwind routes will be open: the upwind route is open while the downwind route is closed, and vice versa. When the sludge removal structure is in the purging and cleaning state, the moisture adsorbed in the drying structure will evaporate and be lost with the high-speed flowing gas, thus restoring the adsorbent material in the drying structure to its original dry state. In the dry adsorption state, the adsorbent material in the drying structure will adsorb water vapor and moist liquid in the flowing gas, thus ensuring that the discharged gas is dry gas and preventing water vapor from condensing and accumulating in the confined space.
[0061] During the hydrogen removal process in a closed environment, the hydrogen removal equipment acquires hydrogen concentration sensor data of the current gas and identifies the type of hydrogen concentration in the current gas based on the hydrogen concentration sensor data.
[0062] The hydrogen concentration types are divided into three categories: no hydrogen concentration, hydrogen-free concentration, and high hydrogen concentration. The no-hydrogen concentration type corresponds to a hydrogen concentration of 0-0.5%, the hydrogen-free concentration type corresponds to a hydrogen concentration of 0.5%-3%, and the high-hydrogen concentration type corresponds to a hydrogen concentration greater than 3%. The terminal adapts to the hydrogen concentration sensor data for the current gas based on the hydrogen concentration range to which the sensor data falls.
[0063] The hydrogen removal equipment controls the hydrogen removal structure by using a hydrogen removal structure control strategy corresponding to the hydrogen concentration type, and performs hydrogen removal treatment on the current gas to obtain hydrogen-removed gas.
[0064] Among them, the hydrogen-free concentration type and the high hydrogen concentration type are both non-hydrogen-removal concentration types. The hydrogen removal structure control strategy for the non-hydrogen-removal concentration type is to directly discharge the current gas into a closed environment without hydrogen removal treatment. The hydrogen removal structure control strategy for the hydrogen removal concentration type is to treat the current gas through a hydrogen removal structure to obtain hydrogen-removed gas.
[0065] The hydrogen removal equipment controls the drying structure to dry the hydrogen-removed gas, thus completing the hydrogen removal task for the current gas.
[0066] Specifically, in the case of non-hydrogen-removed concentration, the drying structure will perform purging and drying treatment on the hydrogen-removed gas, while in the case of hydrogen-removed concentration, the drying structure will perform adsorption and drying treatment on the hydrogen-removed gas.
[0067] Based on the above scheme, the current hydrogen concentration is intelligently determined, and the gas is treated to remove hydrogen and also dried. This not only effectively improves the removal of hydrogen from the gas, but also reduces the amount of water vapor released into the closed environment, thereby effectively reducing the hydrogen removal effect in the closed environment.
[0068] Optionally, when the hydrogen concentration type is a hydrogen elimination type, the hydrogen elimination structure is controlled by the hydrogen elimination structure control strategy corresponding to the hydrogen concentration type to perform hydrogen elimination treatment on the current gas, including: generating a fan speed command for the second explosion-proof fan based on the hydrogen concentration sensor data; controlling the transmission rate of the current gas by the second explosion-proof fan based on the fan speed command, and performing hydrogen elimination treatment on the current gas through the hydrogen elimination structure.
[0069] In this embodiment, the terminal generates a fan speed command for the second explosion-proof fan based on hydrogen concentration sensor data. This fan speed command controls the rotational speed of the second explosion-proof fan, thereby indirectly controlling the gas flow rate to the hydrogen elimination structure. The terminal presets a gas flow rate algorithm and a fan speed algorithm. Then, the terminal first uses the current hydrogen concentration data and the gas flow rate algorithm to calculate the appropriate gas flow rate to be transported to the hydrogen elimination structure. This gas flow rate is then input into the fan speed algorithm to calculate the corresponding fan speed value. Finally, based on this speed value, the terminal queries the specifications of the explosion-proof fan to identify the command corresponding to the speed value and obtain the fan speed command.
[0070] The terminal controls the transmission rate of the current gas by the second explosion-proof fan based on the fan speed command, and performs hydrogen removal treatment on the current gas through the hydrogen removal structure.
[0071] Based on the above scheme, by combining the actual hydrogen concentration data of the current gas, a fan speed command is generated, thereby improving the hydrogen removal efficiency in the current gas.
[0072] Optionally, when the hydrogen concentration type is a non-hydrogen-removal type, the hydrogen removal structure is controlled by the hydrogen removal structure control strategy corresponding to the hydrogen concentration type to remove hydrogen from the current gas, including: generating a start command for the first explosion-proof fan; and controlling the first explosion-proof fan based on the start command to transfer the current gas to the drying structure.
[0073] In this embodiment, the terminal generates a start command for the first explosion-proof fan. This start command controls the first explosion-proof fan to turn on. Then, based on the start command, the terminal controls the first explosion-proof fan to transfer the current gas to the drying structure.
[0074] Based on the above scheme, when the hydrogen concentration in the current gas is too high or almost non-existent, there is no need to perform hydrogen removal treatment. The gas can be directly circulated into a closed space. Furthermore, the gas needs to flow at high speed to purge and dry the drying structure. Therefore, there is no need to control the wind speed of the first explosion-proof fan. It can be directly turned on to the maximum value, thereby effectively improving the circulation efficiency of the current gas and the restoration effect on the drying structure.

These modules can be embedded in or independent of the processor in a computer device, or stored in the memory of a computer device as software, so that the processor can call and execute the operations corresponding to each module.
