Detailed implementation manners

[0023] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0024] As Figures 1 to 5 shown, a water vapor separation and purification device for a portable pure water hydrogen generator of the present utility model includes an outer tube 1. A steam inlet pipe 11 and an exhaust pipe 12 are provided on the side wall of the outer tube 1. A top cover 2 is provided on the outer tube 1. A handle 21 is provided on the top cover 2. A chassis 3 is provided at the bottom of the outer tube 1. A support frame 31 is provided at the bottom of the chassis 3. The outer tube 1, the top cover 2 and the chassis 3 enclose an inner cavity 4. An inner tube 5 is provided in the inner cavity 4. The inner tube 5 divides the inner cavity 4 into a separation cavity 41 and an air outlet cavity 42. The steam inlet pipe 11 communicates with the separation cavity 41, and the exhaust pipe 12 communicates with the air outlet cavity 42. A plurality of communication holes 51 are provided on the side wall of the inner tube 5. The communication holes 51 communicate the separation cavity 41 with the air outlet cavity 42. A water vapor uniform flow assembly 6 and a water vapor separation assembly 7 are sequentially arranged in the inner tube 5 from top to bottom;

[0025] Through optimizing the structural design, adopting a compact structure composed of the outer tube 1, the top cover 2 and the chassis 3, and providing a handle 21 on the top cover 2, not only makes the whole device easy to carry, but also ensures its practicability, which is suitable for scenarios that need to be frequently moved or used at different locations; through the double-layer structure formed by the inner tube 5 and the outer tube 1, and the design of a plurality of communication holes 51 on the side wall of the inner tube 5, it helps the water vapor to effectively condense and settle in the separation cavity 41, while the gas can smoothly pass through the communication holes 51 into the air outlet cavity 42 to achieve efficient water vapor separation; through the setting of the water vapor uniform flow assembly 6 and the water vapor separation assembly 7, the gas flow state is more carefully controlled, further optimizing the water vapor separation efficiency and ensuring the dryness of the output hydrogen.

[0026] The water vapor uniform flow component 6 includes a lower conical section 61. Above the lower conical section 61, there is an upper conical section 62. At the bottom of the lower conical section 61, there is a uniform flow plate 63. The uniform flow plate 63 is provided with a plurality of through holes. Between the lower conical section 61 and the upper conical section 62, there are a plurality of uniform flow pipes 64. The uniform flow pipes 64 are communicated with the lower conical section 61 and the upper conical section 62. Through the design of the cooperation of the lower conical section 61 and the upper conical section 62 with the uniform flow pipes 64, the air flow direction can be effectively guided, so that the gas carrying water vapor gradually decelerates during the flow process, which helps the water droplets to condense, and thus better separates from the gas. The plurality of through holes on the uniform flow plate 63 further evenly distribute the incoming gas, reduce eddy currents and dead corners, ensure the stable flow of the gas, and improve the water vapor separation efficiency.

[0027] As a preference of the above embodiment, the diameter of the lower conical section 61 increases sequentially from top to bottom, and the diameter of the upper conical section 62 decreases sequentially from top to bottom. Through the gradually decreasing diameter of the upper conical section 62 from top to bottom, it helps to smoothly decelerate the air flow, while the gradually increasing diameter of the lower conical section 61 can gradually expand the air flow channel, avoiding drastic speed changes and pressure losses when the air flow passes through different parts, thereby reducing energy consumption and noise. Through the upper conical section 62, the condensed water droplets are urged to slide down along the conical surface, improving the effect of separating the water droplets from the gas.

[0028] As a preference of the above embodiment, sealing plates 65 are provided at the top of the lower conical section 61 and the bottom of the upper conical section 62. The sealing plates 65 are provided with through holes corresponding to the uniform flow pipes 64. Through the sealing plates 65, the sealing performance between the lower conical section 61 and the upper conical section 62 is ensured, preventing the gas from flowing through unexpected positions.

[0029] As a preference of the above embodiment, the water vapor separation component 7 includes multiple layers of filter meshes 71 arranged in parallel. The diameters of the filter holes of the multiple layers of filter meshes 71 decrease sequentially from top to bottom. Through the setting of the multiple layers of filter meshes 71, the effect of hierarchical filtration is achieved, gradually removing the moisture and impurities carried in the gas, and improving the efficiency and thoroughness of water vapor separation.

[0030] As a preference of the above embodiment, a water outlet pipe 32 is provided at the bottom of the chassis 3. The water outlet pipe 32 is communicated with the separation chamber 41. Through the water outlet pipe 32, the function of discharging water is realized. When the water collected in the separation chamber 41 accumulates to a certain extent, it will naturally flow into the chassis and be discharged through the water outlet pipe 32, ensuring the continuous and stable operation of the system.

[0031] As a preference of the above embodiment, a drain valve 33 is provided on the water outlet pipe 32 for controlling the water flow rate in the water outlet pipe 32. Through the drain valve 33, the operator can accurately adjust the water flow speed and drainage volume in the water outlet pipe 32 according to actual needs. When it is necessary to stop draining urgently, the drain valve 33 can be quickly closed, enhancing the controllability and safety of the device.

[0032] Preferably, as in the above embodiments, the bottom of the inner tube 5 is of an inverted conical structure; the inverted conical design helps the water to slide down smoothly, improving the drainage efficiency.

[0033] Preferably, as in the above embodiments, the inner tube 5 is coaxially arranged with the outer tube 1; the coaxial design ensures the precise alignment between the inner tube 5 and the outer tube 1, which helps to improve the mechanical stability and operation smoothness of the whole device, reduce vibration and unnecessary wear; the coaxial design is more compact, occupies less space and is suitable for portable movement.

[0034] Preferably, as in the above embodiments, the handle 21 includes a mounting seat 22, and handles 23 are symmetrically arranged on both sides of the mounting seat 22. The handles 23 are rotatably connected to the mounting seat 22; the rotational connection between the handles 23 and the mounting seat 22 improves the flexibility and comfort during handling; when not in use, the handles 23 are placed against the top cover 2, reducing the space required for storage and transportation and facilitating storage in narrow or crowded environments.

[0035] In the operation of a portable pure water hydrogen generator water vapor separation and purification device of the present utility model, first, the hydrogen generator is connected to the water vapor separation and purification device through a pipeline. The hydrogen generator undergoes an electrolysis reaction to produce hydrogen and oxygen. The hydrogen mixed with a certain amount of water vapor enters the separation chamber 41 inside the outer tube 1 through the steam inlet pipe 11; the gas first enters the water vapor equalizing component 6, where the lower conical section 61, the upper conical section 62 and the equalizing plate 63 work together to equalize the gas flow velocity and distribution, reduce turbulence, and at the same time, during the equalizing process, part of the water vapor begins to condense into small water droplets on the upper conical section 62; the gas after equalizing continues to flow downward and passes through the water vapor separation component 7. Through the filter screens 71 with gradually decreasing pore diameters from top to bottom in multiple layers, hierarchical filtration is achieved, gradually removing the remaining water droplets and particles in the gas and improving the purity of hydrogen; the gas then enters the air outlet chamber 42 through the communication holes 51 on the side wall of the inner tube 5. At this time, most of the moisture has been effectively separated and deposited at the bottom of the separation chamber 41. The drain valve 33 is opened, and the moisture is discharged through the drain pipe 32; after the above series of purification steps, dry and pure hydrogen is output through the outlet pipe 12, ready to be used in a hydrogen fuel cell or other applications that require high-purity hydrogen; when necessary, the device can be easily moved or maintained through the handle 21.

[0036] For the portable pure water hydrogen generator water vapor separation and purification device of the present utility model, its installation method, connection method or setting method are all common mechanical methods, and any implementation that can achieve its beneficial effects can be carried out.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
