[0034] In this embodiment, a method for improving the flow uniformity of a reactor is provided. Figure 2 It is a flowchart of a method for improving the flow uniformity of a reactor according to an embodiment of the present application, as Figure 2 shown, and the process includes the following steps:

[0035] Step S202, obtain the flow field distribution data of the reactor, wherein the reactor is used for electrolytic reaction of wastewater to obtain hydrogen, and the flow field distribution data at least includes fluid velocity data and fluid residence time data;

[0036] Optionally, in the above step S202, the velocity distribution and residence time distribution data of the fluid flow in the reactor can be obtained based on CFD (Computational Fluid Dynamics) simulation or PIV (Particle Image Velocimetry) laser velocimeter, as Figure 3 shown, Figure 3 It is the fluid velocity distribution diagram of the electrode cross-section of the wastewater hydrogen production reactor.

[0037] Step S204, calculate the fluid velocity data of the electrode cross-section of the reactor to obtain a first quantization value, wherein the first quantization value is used to represent the flow uniformity of the electrode cross-section of the reactor;

[0038] Step S206: Calculate the fluid residence time data to obtain a second quantization value, where the second quantization value is used to represent the overall flow uniformity of the reactor.

[0039] Step S208: Adjust the adjustable structure of the reactor according to the first quantization value and the second quantization value to improve the flow uniformity of the reactor.

[0040] Through the above steps, the flow field distribution data of the reactor can be obtained. The flow uniformity of the electrode cross-section of the reactor is quantified according to the fluid velocity data in the flow field distribution data, and the overall flow uniformity of the reactor is quantified according to the fluid residence time data in the flow field distribution data. Then, the reactor structure is adjusted based on the quantization results to improve the flow uniformity. Thus, the problem of how to improve the flow uniformity of the reactor in the related art is solved, and the effect of improving the flow uniformity of the reactor is achieved.

[0041] In an exemplary embodiment, obtaining the flow field distribution data of the reactor includes: establishing a three-dimensional geometric model of the reactor, dividing the fluid domain of the three-dimensional geometric model by unstructured grids to obtain a meshed model; setting the initial parameters of the meshed model, and solving the flow field of the meshed model based on the fluid mechanics equations to obtain the flow field distribution data.

[0042] Optionally, in the above embodiment, establishing a three-dimensional geometric model of the reactor includes dividing the fluid domain by unstructured grids with a grid size of 0.1 - 2 mm to ensure grid encryption on the electrode surface and at the fluid inlet. Then, boundary conditions are set. For example, the wastewater flow rate at the inlet boundary is set to 0.5 - 3 m / s, and the reactant concentration is dynamically adjusted according to the wastewater composition. The outlet boundary is set to atmospheric pressure conditions, and the electrode surface is defined as a no-slip wall surface. Based on the Navier-Stokes equations (the basic equations describing the dynamic behavior of Newtonian fluids under the assumption of a continuous medium in fluid mechanics) and a turbulence model, the velocity distribution data of the electrode cross-section and the residence time distribution function of the entire reactor are derived by solving the flow field distribution through the finite volume method.

[0043] In an exemplary embodiment, calculating the fluid velocity data of the electrode cross-section of the reactor to obtain a first quantization value includes: calculating the fluid velocity data of the electrode cross-section of the reactor according to the following formula to obtain the first quantization value:

[0044]

[0045] where VUI represents the first quantization value, and v(x, y) represents the fluid velocity at the point (x, y) on the electrode cross-section. represents the average fluid velocity across the electrode cross-section, and A represents the area of the electrode cross-section.

The Z-axis is parallel to the reactor, and the point coordinates on the electrode cross-section are represented by the X-axis coordinates and the Y-axis coordinates. The above first quantization value VUI (Velocity Uniformity Index) represents the flow velocity uniformity index. A value close to 1 indicates good uniformity of the electrode cross-section; a value close to 0 indicates worse uniformity of the electrode cross-section.

[0047] In an exemplary embodiment, the fluid residence time data is calculated to obtain a second quantization value, including: calculating the second quantization value according to the following formula for the fluid residence time data:

[0048]

[0049] where θ represents the second quantization value, t m represents the average fluid residence time, τ represents the space time of the reactor, V represents the volume of the reactor, and Q represents the flow rate of the reactor.

[0050] Optionally, in the above embodiments, θ is a dimensionless time quantity. A value close to 1 indicates a higher overall flow uniformity of the reactor. The above average fluid residence time t m The calculation process is as follows:

[0051]

[0052] where E(t) is the residence time distribution function, representing the proportion of substances leaving the system before time t, and N(t) represents the amount of substances leaving the system at time t, represents the total amount of substances, is the normalization condition, and F(t) is the cumulative distribution function, representing the proportion of substances leaving the system before time t.

[0053] In an exemplary embodiment, adjusting the structure of the reactor according to the first quantization value and the second quantization value includes: when it is determined that at least one of the first quantization value belonging to the first preset interval and the second quantization value belonging to the second preset interval does not hold, determining a first electrode spacing value of the reactor, where the first electrode spacing value represents the electrode spacing between the cathode and the anode of the reactor; obtaining a second electrode spacing value from an adjustment value interval preset for the electrode spacing value; and updating the first electrode spacing value to the second electrode spacing value, where the flow uniformity corresponding to the second electrode spacing value is higher than the flow uniformity corresponding to the first electrode spacing value.

[0054] Optionally, for example, define the first preset interval as 0.8 - 1 and the second preset interval as 0.75 - 1. If the first quantization value of the reactor is greater than 0.8 and the second quantization value is greater than 0.75, it indicates that the flow uniformity of the reactor is good and no adjustment is required. If the quantization value of the reactor does not meet the preset interval, the structure of the reactor can be optimized to improve the flow uniformity of the reactor. Specifically, the structure optimization design includes but is not limited to the following operations:

[0055] 1. Electrode spacing adjustment: Control the electrode spacing within the range of 5 - 20 mm, and adjust the spacing gradient according to the VUI value to optimize the local flow velocity distribution;

[0056] 2. Reactor shape optimization: Design the reactor main body as a gradually expanding or gradually contracting structure to reduce flow dead zones, and control the aspect ratio within 3:1 - 5:1;

[0057] 3. Inlet layout improvement: Adopt a multi-inlet symmetric distribution design, with the number of inlets being 2 - 4, and the flow velocity deviation of a single inlet not exceeding ±10%.

[0058] In an exemplary embodiment, after adjusting the adjustable structure of the reactor, the method further includes: performing an electrolysis reaction on wastewater in the reactor after adjusting the adjustable structure to obtain hydrogen, measuring the energy consumption cost and hydrogen production of the electrolysis reaction; calculating the unit hydrogen production cost according to the energy consumption cost and the hydrogen production, and when it is determined that the difference between the unit hydrogen production cost and the initial unit hydrogen production cost is greater than a preset difference, using the adjusted reactor to produce hydrogen.

[0059] Optionally, through the above embodiments, the flow uniformity of wastewater hydrogen production reactors of different scales and types can be evaluated, providing data support for the optimized design of the reactor structure, and further improving the energy efficiency and economy of the wastewater hydrogen production reaction. In addition to the field of wastewater hydrogen production, the present application can also be applied to other chemical processes that require high-efficiency fluid flow uniformity, such as sewage treatment, biological fermentation and other fields.
