Description

Technical Field

[0001] The present application relates to the field of fuel preparation technology, and in particular to a wind power-based coordinated hydrogen preparation method. Background Art

[0002] As a fuel, hydrogen has a wide range of application scenarios, and the preparation of hydrogen has also become one of the main development directions of fuel preparation technology. For example, the publication (announcement) number is CN104327902A, and the patent title is: "A device for desulfurizing and producing hydrogen by electrolyzing water-coal slurry" (main classification number: C10L9 / 02). The electrolyte used is recycled, saving time and resources, with mild reaction and convenient operation. For another example, the publication (announcement) number is CN110819418A, and the patent title is: "A method for efficient desulfurization and hydrogen production based on solar energy STEP thermal-electrochemical coupling" (main classification number: C10L9 / 02), which realizes the preparation of hydrogen based on solar energy. On the one hand, it can be shown that the preparation technology of hydrogen as a fuel has strong technical feasibility; on the other hand, it can also be shown that the technical mining in this field still has a relatively broad expansion prospect.

In order to achieve these conditions, there will be a certain consumption of electric energy. If the electricity that wind turbines can feed into the power grid is affected in order to meet the conditions for hydrogen production, it will affect the electricity consumption of enterprises and residents. How to effectively convert the remaining electricity into chemical energy such as hydrogen on the basis of meeting the electricity consumption of enterprises and residents to achieve the synergy between power supply and hydrogen production has become an urgent problem to be solved.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, and this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0020] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0021] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0022] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, the wind power-based hydrogen synergistic production method in this specification includes the following steps: S100: using the surplus electric energy generated by the wind turbine generator set but not fed into the power grid to heat the electrolyte in the second electrolytic cell.

[0024] The method in this specification is based on a collaborative hydrogen production device, which includes a first electrolyzer and a second electrolyzer arranged on the outer peripheral side of the first electrolyzer. The internal spaces of the first electrolyzer and the second electrolyzer are isolated, so that there is no material exchange between the first electrolyzer and the second electrolyzer, but there is heat exchange, and the heat exchange can be in the form of thermal radiation. In an optional embodiment of the present specification, the collaborative hydrogen production device also includes a thermal insulation layer; the thermal insulation layer is arranged on the side of the second electrolyzer facing the external environment. In addition, the collaborative hydrogen production device in this specification may also include an electrode arranged in the first electrolyzer, an electrode arranged in the second electrolyzer, a downstream hydrogen evolution device, etc.

[0025] The surplus electric energy in this specification refers to the electric energy that cannot be connected to the power grid and cannot be consumed by other means. The cooperative hydrogen production device in this specification can be completely powered by wind turbines, so it is difficult to accurately estimate the amount of surplus electricity at different times. In other words, at different times, the cooperative hydrogen production device can provide different conditions for hydrogen production. When the surplus electricity is not enough to provide complete hydrogen production conditions, you can first choose to use the surplus electricity to heat the electrolyte in the second electrolyzer. As for whether the temperature of the heated electrolyte can reach the reaction temperature of the hydrogen production reaction, it depends on the amount of surplus electricity. The hydrogen production reaction in this specification is hydrogen production by electrolysis, so the electrolyte can be water, or other catalysts can be added.

[0026] Of course, in an online production environment, it is possible that all the electricity obtained by the wind turbine generator set is connected to the power grid and there is no surplus electricity, so there is no need to execute the method in this specification.

[0027] S102: When the first condition is met, energize the electrodes in the second electrolytic cell so that the current of the electrodes in the second electrolytic cell reaches a first current.

[0028] The electrolysis reaction cannot be carried out by simply heating the electrolyte; the electrolyte must also be energized.

[0029] The first condition in this specification includes one of the following: the duration of the wind turbine generator set being in a full-load state reaches a preset first duration, and the duration of the electrolyte heating in the second electrolyzer reaches a preset second duration (indicating that the wind turbine generator set is outputting electrical energy at a relatively large power for a certain period of time, the probability of an instantaneous decrease in output power is relatively small, and the remaining electrical energy is relatively sufficient, and the possibility of achieving hydrogen production is relatively large), wherein the first duration and the second duration can both be empirical values, which are related to the capacity of the wind turbine generator set; the temperature of the electrolyte in the second electrolyzer reaches the first reaction temperature (indicating that the reaction conditions have been met), and the first reaction temperature is the reaction temperature of the second electrolyzer that can achieve the highest efficiency under the condition of the first current when the reaction is stable (stable reaction is a reaction state in which the reaction rate changes less, which can be regarded as a constant reaction rate). The correspondence between the first current and the first reaction temperature can be obtained by experiment. In this specification, the first reaction temperature is a reaction temperature with a lower reaction rate. This correspondence is related to factors such as catalysts. In the case where the second electrolyzer is an electrolyzer based on anion exchange membrane technology, the first reaction temperature is between 50 degrees Celsius and 70 degrees Celsius. The hydrogen production process in this specification is intended to keep the reaction in a stable state, thereby ensuring energy conversion efficiency.

[0030] S104: When the second condition is met, increasing the current of the electrodes in the second electrolytic cell to a second current.

[0031] Due to the conditions of wind power generation, the surplus electric energy may be on an increasing trend, and the first reaction temperature may not be able to achieve the full conversion of the surplus electric energy, and the reaction needs to be adjusted smoothly.

[0032] The second condition in this specification includes one of the following: within a first time period after the first condition is met (the first time period may be an empirical value, which is related to the capacity of the wind turbine generator set and the historical demand for electric energy of the power grid), the change in the instantaneous output power of the wind turbine generator set is less than a preset change threshold, and the oxygen content of the electrolyte in the second electrolyzer reaches a preset oxygen content threshold (indicating that the output of the wind turbine generator is stable, and the electrolysis reaction in the second electrolyzer has reached the maximum reaction efficiency under the current reaction conditions, and there are conditions for improving the reaction efficiency. The change threshold may be an empirical value. The oxygen content threshold may be the saturated content of oxygen in the electrolyte under the current conditions); the temperature of the electrolyte in the second electrolyzer reaches a second reaction temperature, which is the reaction temperature of the second electrolyzer that can achieve the highest efficiency and stable reaction under the second current (the second reaction temperature is higher than the first reaction temperature. In order to meet the needs of the hydrogen production reaction, in addition to power supply from other aspects, the remaining electric energy is used to heat the second electrolyzer, that is, the temperature of the second electrolyzer also has the function of monitoring the amount of remaining electric energy. The temperature of the second electrolyzer reaches the second reaction stability, indicating that there is a lot of remaining electric energy and the reaction rate should be increased). The corresponding relationship between the second reaction temperature and the second current can also be obtained through experiments.

[0033] In an optional embodiment of the present specification, when the second electrolytic cell is an electrolytic cell based on anion exchange membrane technology, the second reaction temperature is between 70 degrees Celsius and 90 degrees Celsius.

[0034] S106: If it is detected that the temperature of the electrolyte in the first electrolytic cell reaches the first reaction temperature, energize the electrodes in the first electrolytic cell so that the current of the electrodes in the first electrolytic cell reaches the first current, so that the first electrolytic cell performs an electrolytic hydrogen production reaction.

[0035] Since the second electrolytic cell is arranged on the outer peripheral side of the first electrolytic cell, the second electrolytic cell can also serve to heat the first electrolytic cell. When the amount of residual electric energy is large and the reaction of the second electrolytic cell is not sufficient to completely convert it into chemical energy, the first electrolytic cell can also carry out hydrogen production reaction to improve the energy conversion efficiency.

[0036] When the output power of the wind turbine generator set is continuously high, the amount of residual electric energy may be large. At this time, the first electrolyzer has reached a stable reaction and should not be destroyed. In an optional embodiment of the present specification, when the first electrolyzer has been performing a hydrogen production reaction under the first current, the heating of the first electrolyzer is turned on (a heating device may be provided in the first electrolyzer), and the reaction in the first electrolyzer reaches a stable reaction corresponding to the second reaction temperature.

[0037] In an optional embodiment of the present specification, the first electrolytic cell is also an electrolytic cell based on anion exchange membrane technology, and the composition of the material in the first electrolytic cell can be the same as the composition of the material in the second electrolytic cell. In order to improve the first electrolytic cell's ability to switch from a stable reaction corresponding to the first reaction temperature to a stable reaction corresponding to the second reaction temperature more sensitively, and to avoid the second electrolytic cell heating the first electrolytic cell and causing the second electrolytic cell to heat too slowly, in an optional embodiment of the present specification, the capacity of the first electrolytic cell is less than the capacity of the second electrolytic cell. According to the temperature of the electrolyte in the first electrolytic cell, a temperature variation curve is drawn; when the temperature variation curve indicates that the first electrolytic cell is in a heating state, and the heating rate is greater than a preset rate threshold, the judgment of the first condition is performed; the rate threshold is negatively correlated with the difference in the capacity of the first electrolytic cell and the second electrolytic cell.

[0038] The technical solution in the present application realizes the coordination between power supply for the power grid and hydrogen production through the design of the cooperative hydrogen production device, and ensures that the surplus electric energy is more effectively converted into the chemical energy of hydrogen while ensuring the power supply demand. The first electrolyzer is surrounded by the second electrolyzer. In addition to adjusting the reaction conditions of the second electrolyzer, the heat provided by the cooperative hydrogen production device to the second electrolyzer can also indirectly adjust the reaction conditions for the first electrolyzer, and the electrolyte in the first electrolyzer can also provide insulation for the reaction in the second electrolyzer through its heat capacity to improve the energy conversion rate of the surplus electric energy. When the chemical reaction is in a stable state, its energy conversion efficiency is more stable than that in a non-steady state, and it is also beneficial to the efficiency of the downstream hydrogen precipitation process, thereby improving the overall working efficiency of the cooperative hydrogen production device and reducing the overall energy consumption of the cooperative hydrogen production device. In the method in the present application, under certain conditions, the first electrolyzer can also carry out hydrogen production reaction. Although the hydrogen production efficiency may not be higher than that of the second electrolyzer, when the electrolyte temperature is appropriate, the surplus electric energy can also be converted into chemical energy, thereby improving the hydrogen production efficiency.

[0039] The electric energy output by the wind turbine generator set may be in an increasing trend or in a decreasing trend. In the case where the electric energy output by the wind turbine generator set is in a decreasing trend, the remaining electric energy will also decrease. In an optional embodiment of the present specification, it is determined whether the third condition is met. If the third condition is met, stop energizing the electrodes in the first electrolyzer (if the heating device in the first electrolyzer is turned on, the heating device in the first electrolyzer also needs to be turned off); the third condition includes: the duration of the change in the instantaneous output power of the wind turbine generator set is greater than the change threshold, and is greater than a preset third duration (indicating that there is fluctuation, and the fluctuation is continuous, making it difficult to provide stable conditions for hydrogen production under current conditions); the third duration is negatively correlated with the maximum single-unit capacity of the wind turbine generator set (fluctuations are mostly caused by wind conditions, and the larger the single-unit capacity, the higher the possibility of increased fluctuations, resulting in more obvious fluctuations and easy to detect), negatively correlated with the total capacity of the wind turbine generator set, and positively correlated with the volume of the second electrolyzer (due to the large specific heat capacity of water, the larger the volume, the more obvious the delay caused by the impact of changes in reaction conditions, and there is no need to rush to adjust).

[0040] As the output power of the wind turbine generator set further decreases, the remaining electric energy will also further decrease. When the fourth condition is reached, stop energizing the electrodes in the second electrolytic cell; the fourth condition includes: the temperature of the electrolyte in the first electrolytic cell is lower than the first reaction temperature. In this specification, in addition to being able to keep the second electrolytic cell warm, the temperature of the first electrolytic cell also has the function of detecting the remaining electric energy. When the temperature of the first electrolytic cell is lower than the first reaction temperature, it indicates that the temperature of the second electrolytic cell has also dropped to near the first reaction temperature, or even below the first reaction temperature, and at this time the remaining electric energy is still on a downward trend. It is difficult to continue to power the electrodes and maintain the electrolysis reaction. Therefore, the electrolysis reaction in the second electrolytic cell is stopped.
