In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0048] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0049] See also Figure 1-9 The utility model provides a technical solution: a steam separation container for hydrogen production and purification, comprising a base 1, a container lower shell 2, a container upper shell 3, a top cover 4 and a reinforcement mechanism 5.

[0050] The base 1, the container lower shell 2, the container upper shell 3, and the top cover 4 are fixedly connected in sequence from bottom to top.

[0051] A drain pipe 21 is integrally connected to the lower end of one side of the container lower shell 2 .

[0052] A feed pipe 31 is integrally connected to the bottom of the container upper shell 3, and the lower end of the feed pipe 31 is transversely fixed and penetrated into one side of the upper end of the container lower shell 2. A discharge pipe 1 32 is integrally connected to one side of the container upper shell 3, and a discharge pipe 2 33 is integrally connected to the other side of the container upper shell 3. A discharge pipe 3 34 is integrally connected to the back of the container upper shell 3, and a plurality of drainage holes 38 are opened through the bottom of the container upper shell 3.

[0053] The bottom of the feed pipe 31 is fixedly connected with a liquid accumulation pipe 311, and the liquid accumulation pipe 311 is arranged outside the lower shell 2 of the container. Specifically, by setting the liquid accumulation pipe 311, it is possible to avoid excessive liquid accumulation inside the feed pipe 31 to affect the steam flow and separation effect, avoid the problem of liquid accumulation caused by excessive moisture content in the input steam, and reduce heat loss and pollution risks.

[0054] The inner side of the container upper shell 3 is fixedly connected with a folding plate 1 35 , a folding plate 2 36 and a folding plate 3 37 in sequence from bottom to top.

[0055] The front of the folding plate 1 35, the folding plate 2 36 and the folding plate 3 37 are in a matching "V" shaped structure. The folding plate 1 35 is located in the center of the inner side of the container upper shell 3 in the vertical direction, the folding plate 2 36 is located on the left side of the inner side of the container upper shell 3 in the vertical direction, and the folding plate 3 37 is located on the right side of the inner side of the container upper shell 3 in the vertical direction. For details, refer to the attached manual Figure 4-9After the steam is input from the feed pipe 31, the steam first collides with the fold plate 1 35, and then the steam continues to rise from the gaps on both sides of the fold plate 1 35, and then the steam collides with the fold plate 2 36, and the steam continues to rise from the gap on the right side of the fold plate 2 36, and then the steam collides with the fold plate 37, and finally the steam continues to rise from the gap on the left side of the fold plate 37. In the process of the steam colliding with the fold plates 1 35, 2 36 and 37, the gathered water droplets will accumulate on the fold plates 1 35, 2 36 and 37, thereby removing the liquid medium in the steam medium to achieve the purification effect. Since the suspended water droplets have a large mass and inertia, they condense and fall to the inner bottom of the upper shell 3 of the container, and finally fall into the lower shell 2 of the container through the drainage hole 38.

[0056] Specifically, by setting the folding plate 1 35, the folding plate 2 36 and the folding plate 3 37, the retention time of the steam inside the container is increased, the fluid changes the flow direction multiple times in the container, the chance of the steam colliding with the solid component is increased, and the separation efficiency and quality are improved.

[0057] A top row of pipes 41 is integrally connected to the top of the top cover 4 .

[0058] The reinforcement mechanism 5 is arranged on the base 1, and includes a first ring body 51, a second ring body 52, a plurality of groups of reinforcement bolts 53, a plurality of groups of nuts 54 and a plurality of groups of brackets 55, wherein:

[0059] The first ring body 51 is connected to the top of the base 1;

[0060] The second ring body 52 is connected to the lower end surface of the container lower shell 2;

[0061] A plurality of groups of reinforcing bolts 53 are fixedly connected to the top of the base 1 in a regular annular array, and the reinforcing bolts 53 are passed through the inner sides of the first ring body 51 and the second ring body 52;

[0062] A plurality of sets of nuts 54 are respectively connected to the upper ends of a plurality of sets of reinforcing bolts 53 through threaded structures;

[0063] A plurality of sets of brackets 55 are fixedly connected between the top of the first ring body 51 and the top of the second ring body 52 , and the plurality of sets of brackets 55 are arranged in a regular annular array.

[0064] For details, please refer to the attached manual. Figure 1-3 The side of the bracket 55 close to the lower shell 2 of the container is designed as an inclined surface. A group of reinforcing bolts 53 is provided between every two groups of brackets 55. The bracket 55 plays a protective role for the reinforcing bolts 53. The first ring body 51 and the second ring body 52 are fixed to the top of the base 1 and the outer side of the lower shell 2 of the container through nuts 54.

[0065] The lower shell 2 of the container is a truncated cone-shaped hollow structure, and the inner wall surface of the first ring body 51 and the inner wall surface of the second ring body 52 are both connected to the surface of the lower shell 2 of the container. Specifically, the lower shell 2 of the container is a truncated cone-shaped hollow structure that is narrow at the top and wide at the bottom, which effectively increases the space of the lower shell 2 of the container, facilitates the collection and discharge of liquid, and makes the overall center of gravity of the container sink. The inner diameter length of the first ring body 51 is smaller than the inner diameter length of the second ring body 52. ​​The inner walls of the first ring body 51 and the second ring body 52 are tightly fitted on the surface of the lower shell 2 of the container. The first ring body 51 and the second ring body 52 have a limiting effect on the lower shell 2 of the container, which can increase the strength and stability of the lower shell 2 of the container and prevent deformation or rupture caused by pressure changes.

[0066] The middle parts of the folding plate 1 35, the folding plate 2 36 and the folding plate 3 37 are all provided with through holes. Figure 6-8 The through hole is a rectangular structure. The setting of the through hole can increase the fluidity and distribution uniformity of the steam, and can prevent the accumulation or blockage of droplets on the folding plate, and discharge the droplets in time to avoid affecting the separation effect.

[0067] Specifically, flanges are installed on the drain pipe 21, feed pipe 31, liquid accumulation pipe 311, drain pipe 1 32, drain pipe 2 33, drain pipe 3 34, and top drain pipe 41 to facilitate the connection of external output pipelines and equipment. Valves can also be installed on the pipelines to achieve pipeline closure.

[0068] Specifically, row pipe 1 32 and row pipe 2 33 are both arranged horizontally to facilitate the connection of horizontal output pipes and equipment. Row pipe 1 32 and row pipe 2 33 are both arranged above folding plate 3 37 in a horizontal position, and the inner diameter length of row pipe 1 32 is smaller than the inner diameter length of row pipe 2 33, which can meet the parameter requirements of external equipment that accepts different input amounts.

[0069] Specifically, the drain pipe 34 is arranged in a horizontal position below the folding plate 1 35. The drain pipe 34 can be installed with pressure monitoring equipment such as pressure sensors through flange parts, so as to realize the function of monitoring the internal pressure of the container and improve safety.

[0070] Specifically, the top row of pipes 41 is vertically arranged to facilitate connection with the longitudinal output pipelines and equipment above.

[0071] Specifically, the steam separation container for hydrogen production and purification is provided with a plurality of discharge pipes, which facilitates the discharge of reactants and products and increases the operational flexibility and controllability of the container.

[0072] Specifically, the steam separation container for hydrogen production and purification utilizes structures such as folding plates and drainage holes 38 provided in the container to achieve effective separation and collection of steam and liquid. Under the action of the folding plates, the steam and liquid collide and condense. The liquid flows along the folding plates to the lower shell 2 of the container and is discharged through the drain pipe 21, while the steam continues to rise to the top of the container and is output through the top drain pipe 41, drain pipe one 32, and drain pipe two 33. The container can greatly improve the purity of the steam and provide higher-purity steam for the next work section.

[0073] Specifically, the steam separation container for hydrogen production and purification has a simple structure, low manufacturing cost, and easy operation. It can effectively avoid liquid contamination and interference with steam, ensure the efficiency and quality of steam separation, save energy consumption, reduce operating costs, and improve hydrogen production efficiency.
