Optionally, in this embodiment, on the basis of the coal ash having been subjected to acid leaching treatment, the coal ash after the acid leaching treatment is subjected to material extraction to obtain metal oxides, for example, aluminum-containing fly ash after the acid leaching treatment is subjected to material extraction to obtain aluminum oxide, which is only used as an example and is not specifically limited.

[0054] As an optional embodiment, the method further includes: using steam to drive a steam turbine in the nano-carbon hydrogen unit; controlling the steam turbine to drive a generator in the nano-carbon hydrogen unit to generate electricity to obtain the first electrical energy.

[0057] In this embodiment, after using steam to drive the steam turbine in the nano-carbon hydrogen unit, the steam turbine is controlled to drive the generator in the nano-carbon hydrogen unit to generate electricity to obtain the first electric energy. Optionally, this embodiment controls the steam turbine to drive the generator in the nano-carbon hydrogen unit to generate electricity on the basis of driving the steam turbine in the nano-carbon hydrogen unit to obtain the first electric energy.

[0058] As an optional implementation method, step S104, based on the second installed capacity of the photovoltaic group in the electrolysis system, electrolyzes the metal oxide to obtain the metal element, including: based on the second installed capacity, controlling the photovoltaic group to convert light energy to obtain second electrical energy; based on the first electrical energy and the second electrical energy, electrolyzes the metal oxide to obtain the metal element.

[0059] In this embodiment, the second electric energy can be used to represent the electric energy generated by photovoltaic power generation.

[0060] In this embodiment, after the metal oxide is extracted from the processed raw coal, the photovoltaic unit is controlled to convert the light energy based on the second installed capacity to obtain the second electric energy. Optionally, based on the extraction of the metal oxide, the embodiment adjusts the adapted installed capacity of the photovoltaic unit in the electrolysis system to obtain the second installed capacity. According to the obtained second installed capacity, the photovoltaic unit in the electrolysis system is controlled to convert the light energy to obtain the second electric energy.

[0061] In this embodiment, after the photovoltaic unit is controlled to convert light energy based on the second installed capacity to obtain the second electric energy, the metal oxide is electrolyzed based on the first electric energy and the second electric energy to obtain the metal element. Optionally, based on the determination of the second electric energy, this embodiment uses the electric energy generated by thermal power generation and the electric energy generated by photovoltaic power generation to electrolyze the metal oxide to obtain the metal element.

For example, a solution containing aluminum ions is electrolyzed to obtain aluminum element, which is only used as an example and is not specifically limited.

[0066] In the embodiment of the present invention, when electrolyzing metal, the first installed capacity of the nano-carbon hydrogen unit in the electrolysis system can be determined. According to the determined first installed capacity, the raw coal in the nano-carbon hydrogen unit can be processed, and metal oxides can be extracted from the processed raw coal, and according to the second installed capacity of the photovoltaic unit in the electrolysis system, the metal oxides can be electrolyzed to obtain metal elements, thereby achieving the purpose of avoiding the generation of a large amount of carbon emissions in the process of electrolyzing aluminum oxide using electricity generated by thermal power generation, thereby solving the technical problem of high carbon emissions during aluminum electrolysis, and further achieving the technical effect of increasing carbon emissions during aluminum electrolysis.

[0067] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0068] In the process of electrolysis of aluminum, aluminum oxide is electrolyzed using electricity generated by thermal power generation to obtain aluminum. However, in the process of electrolyzing aluminum oxide using electricity generated by thermal power generation, a large amount of carbon emissions will be generated, resulting in a technical problem of high carbon emissions during electrolysis of aluminum.

[0069] In order to solve the above technical problems, an embodiment of the present invention proposes a method for electrolyzing metals. When electrolyzing metals, the first installed capacity of the nano-carbon hydrogen unit in the electrolysis system can be determined. According to the determined first installed capacity, the raw coal in the nano-carbon hydrogen unit can be processed, and metal oxides can be extracted from the processed raw coal. According to the second installed capacity of the photovoltaic unit in the electrolysis system, the metal oxides can be electrolyzed to obtain metal elements, thereby achieving the purpose of avoiding the generation of a large amount of carbon emissions in the process of electrolyzing aluminum oxide using electricity generated by thermal power generation, thereby solving the technical problem of high carbon emissions during aluminum electrolysis, and further achieving the technical effect of increasing carbon emissions during aluminum electrolysis.

[0070] In this embodiment, the metal electrolysis method in this application can be realized through a coal-electricity-aluminum integrated energy system for a low-carbon circular economy. For example, FIG2(a) is a schematic diagram of a coal-electricity-aluminum integrated energy system for a low-carbon circular economy according to an embodiment of the present invention. As shown in FIG2(a), the system combines thermal power generation, electrolytic aluminum, and photovoltaic power generation into a system that can fully utilize matter and energy. In this system, high-aluminum coal is processed by nano-processing technology to obtain coal-based nano-carbon hydrogen fuel (containing aluminum); after the above-mentioned coal-based nano-carbon hydrogen fuel is burned, boiler steam and aluminum-containing fly ash under high temperature and high pressure can be obtained; in the electrolysis system 205, the aluminum-containing fly ash is subjected to acid leaching treatment, and aluminum oxide can be extracted from the aluminum-containing fly ash after acid leaching treatment, wherein the remaining part after acid leaching can be sold as ordinary fly ash for use as building materials; thermal energy is provided by a part of the steam in the boiler steam, and the aluminum-containing fly ash can be subjected to acid leaching treatment by using the above-mentioned thermal energy provided, and the steam turbine 201 in the nano-carbon hydrogen unit is driven by another part of the steam in the boiler steam, and the driven steam turbine 201 is controlled to drive the generator 202 in the nano-carbon hydrogen unit to generate thermal power, and the electric energy generated by thermal power generation can be obtained; the electric energy generated by the thermal power generation system 203 and the electric energy generated by the photovoltaic system 204 are used to electrolyze aluminum oxide to obtain aluminum element.

[0071] In this embodiment, the high-aluminum coal, water and a small amount of additives can be processed through an advanced nano-processing process to produce a liquid coal-based special fuel with a basic particle size of nanometers and high surface activity - coal-based nano-hydrocarbon fuel (containing aluminum). The fuel has at least one of the following characteristics: low calorific value of the raw materials, low fuel solid content, low ignition temperature and high fuel calorific value.

[0072] In this embodiment, the flow of the above-mentioned substances and energy can be shown in Figure 2(b), which is a schematic diagram of the flow of substances and energy according to an embodiment of the present invention. Among them, by performing a combustion operation on the coal-based nano-carbon hydrogen fuel, aluminum-containing fly ash can be obtained, and the aluminum-containing fly ash is subjected to acid leaching treatment. Alumina can be extracted from the aluminum-containing fly ash after the acid leaching treatment. In addition, aluminum oxide can also be extracted from aluminum ore. Electrolysis of the extracted aluminum oxide can obtain aluminum element and CO2. Aluminum-containing fly ash can be used to make fly ash sintered bricks. By performing a combustion operation on the coal-based nano-carbon hydrogen fuel, CO2 can be obtained, and the process of making fly ash sintered bricks can use the obtained CO2. The electric energy required for the above-mentioned electrolytic aluminum process can be provided by the electric energy generated by thermal power generation and the electric energy generated by photovoltaic power generation.

[0073] For example, in the coal-electricity-aluminum integrated energy system for a low-carbon circular economy, 2.927×107 KJ heat calculation, assuming that 40% of it is converted into electrical energy, can generate 1.1708×10 7 KJ of electricity. The average electricity consumption for producing one ton of aluminum is 1.3×10 4 KWh, which is 4.68×10 7 KJ. Take α = 0.4, that is, photovoltaic power generation accounts for 0.4 of the electricity required for electrolytic aluminum, and thermal power generation accounts for 0.6. Therefore, thermal power generation is required to provide 4.68×10 7 KJ×0.6=2.808×10 7 KJ of electricity. It can be calculated that under this structure, each ton of electrolytic aluminum needs to burn (2.808×10 7 KJ) / (1.1708×10 7 KJ) = 2.4 tons of standard coal to provide electricity, while 4 tons of standard coal were needed before the introduction of this structure. Among them, 2.4 tons of standard coal can produce 0.3312 tons of aluminum fly ash when burned. If the aluminum oxide content in the aluminum fly ash is 38%, it can produce 0.0666 tons of electrolytic aluminum. If the aluminum ore contains 65% aluminum oxide, 2.71244 tons of aluminum ore need to be purchased for each ton of aluminum obtained by electrolysis.

[0074] First, calculate carbon emissions.

[0075] First, regarding the coal combustion part: the relationship between the mass of CO2 produced by coal combustion, the mass of fly ash and the mass of coal can be shown as follows:

[0076] m CO21 =k1k2m coal (1)

[0077] m ash =k3m coal (2)

[0078] Among them, m CO21 Can be used to express the mass of CO2, m ash Can be used to express the mass of fly ash, m coal It can be used to indicate the quality of coal. It should be noted that this part is the direct emission of carbon dioxide, which is included in the calculation of carbon tax.

[0079] Furthermore, k1 = 2.5, k3 = 0.138, that is, 1 ton of standard coal burns to produce 2.5 tons of CO2 and 0.138 tons of fly ash; the conversion coefficient of clean coal to standard coal k2 = 0.9. The relationship between the mass of alumina in fly ash and the mass of fly ash can be shown as follows:

[0080] m Al2O31 =k4m ash (3)

[0081] Among them, k4=0.38, that is, the content of aluminum oxide in fly ash is 38%.

[0082] Second, regarding the secondary utilization of fly ash: the recycling of other elements in fly ash, such as gallium, lithium, scandium, etc., is not considered. The rest of the fly ash can be mixed into concrete, bricks, etc. as building materials to make full use of it, because fuel is needed when sintering bricks, and the combustion of fuel requires the emission of carbon dioxide. Taking the fly ash sintered bricks made by mixing 80% fly ash as an example to calculate its carbon emissions. For every 10,000 bricks produced, about 0.6 tons of standard coal can be saved. Each fly ash sintered brick weighs about 1.67kg, and the mass of fly ash is 1.336kg. The relationship between the mass of fly ash and the mass of standard coal saved can be shown as follows:

[0083] Δm coal =k5(1-k4)m ash (4)

[0084] Among them, according to the proportion calculation, k5 = 0.045. It should be noted that this part is an indirect reduction of carbon dioxide emissions and is not included in the calculation of carbon tax.

[0085] Third, for electrolytic aluminum: According to the chemical formula of electrolytic aluminum The relationship between CO2 and Al2O3 produced by electrolytic aluminum can be obtained as shown in the following formula:

[0086]

[0087] According to the chemical equation, k6 = 0.65. It should be noted that this part is the direct emission of carbon dioxide and is included in the calculation of carbon tax.

[0088] Fourth, regarding the restoration of green plants on reclaimed land: the land area of ​​a 100MW open-pit mine reclamation area governance photovoltaic project is 262.6452 hectares. If the average green plant absorbs 10 tons of carbon dioxide per hectare per year, it can reduce carbon dioxide emissions by 2,626.452 tons per year. It should be noted that this part is an indirect reduction of carbon dioxide emissions and is not included in the calculation of carbon tax.

[0089] Furthermore, according to the calculation of the electric energy required for electrolytic aluminum mentioned above, the aluminum oxide extracted from the fly ash produced by coal combustion required to produce one ton of aluminum is far from enough to meet the aluminum oxide consumed by electrolytic aluminum. Among them, the proportion of aluminum extracted from fly ash is β = 0.0666. Without considering the carbon dioxide emitted from other processes such as aluminum production from aluminum ore, the total carbon dioxide emitted from producing one ton of aluminum can be shown as follows:

[0090]

[0091] Among them, it is calculated that the direct CO2 carbon emissions after the introduction of photovoltaic power generation are: 6.63 tons, and the direct CO2 carbon emissions without the introduction of photovoltaic power generation are: 10.23 tons. The secondary utilization of fly ash building materials can reduce carbon dioxide emissions as shown in the following formula:

[0092]

[0093] From the above, it can be seen that through comparison, it can be found that the structure proposed in this application can significantly reduce the emission of carbon dioxide both directly and indirectly.

[0094] Second, calculate the cost savings.

[0095] First, regarding the carbon tax part: the carbon emission cost is 30 yuan / ton of CO2. When the coal-electricity-aluminum integrated structure is not introduced, the carbon emission cost of producing one ton of aluminum is 306.9 yuan. After the coal-electricity-aluminum integrated structure is introduced, the carbon emission cost of producing one ton of aluminum is 198.9 yuan.

[0096] Second, regarding the cost of aluminum ore: based on an aluminum ore price of 1,000 yuan / ton and containing 65% alumina (excluding transportation costs), the cost of purchasing aluminum ore before the introduction of this structure is 2,905.98 yuan, and the cost of purchasing aluminum ore after the introduction of this structure is 2,712.44 yuan (based on the value of aluminum ore).

[0097] Third, regarding the cost of coal: 2.4 tons of standard coal are needed for each ton of electrolytic aluminum, while 4 tons of standard coal were needed before the introduction of this structure. Calculated at 1,200 yuan per ton of standard coal, the cost of coal-fired power generation is 2,880 yuan and 4,800 yuan respectively (in terms of standard coal value).

[0098] Fourth, for the secondary utilization of fly ash: without considering the recycling of other elements in fly ash (such as gallium, lithium and scandium, etc.), the fly ash is sold at 100 yuan / ton, then its recoverable cost is 2.4k3(1-k4)×100=20.5 yuan, and all the fly ash is sold before the introduction of this structure, and the recoverable cost is 4k3×100=55.2 yuan. In summary, the cost of aluminum per ton is 7957.68 yuan (including coal cost) before the introduction of the coal-electricity-aluminum integrated structure, and the cost of aluminum per ton is 5770.84 yuan (including coal cost) after the introduction of the coal-electricity-aluminum integrated structure. It can be seen from this that the introduction of the system in this application can greatly reduce the cost of producing aluminum.

After the introduction of photovoltaic power generation, the total power generation cost is 0.45×0.6+0.1×0.4=0.31 yuan / kWh. The weight coefficient is taken as 0.4.

[0106] In terms of recycling benefits: ① The comprehensive energy consumption of electrolytic aluminum is 2.4 tons of standard coal per ton of commercial aluminum, and the weight coefficient is 0.2; ② The standard coal consumption for power generation is calculated as follows: but Take the weight coefficient as 0.1; ③ Alumina consumption

[0107] 2.71244×0.65=1763.09 kg, and the weight coefficient is 0.1.

[0108] It should be noted that in this application, the expert consultation method is adopted to divide the evaluation results of each indicator into 5 levels: excellent, good, medium, low and poor. Among them, the formulation of the standard values ​​of each indicator has consulted the opinions of industry managers, front-line employees, government managers and experts, and also referred to industry standards and local standards, see Table 3 below:

[0109] Table 3 Standard values ​​for evaluation of various indicators

[0110]

[0111]

[0112] According to Table 3 and the calculated economic and recycling benefits, the detailed scores of each indicator can be calculated, and combined with the weight coefficients of each indicator, the overall weighted score can be further calculated. Finally, the excellence of the structure is evaluated based on the weighted score, and the calculation results are shown in Table 4.

[0115] Furthermore, for system planning and design optimization:

[0116] On the basis of the original structure, comprehensive consideration is given to electricity (installation cost, operating cost and income, etc.), heat (profit from heat sales of cogeneration units), carbon emissions (carbon tax costs) and electrolytic aluminum production benefits. The photovoltaic output data of a typical photovoltaic day is used as the photovoltaic power data, and multi-objective optimization is carried out to improve the system planning and design. The optimal installed capacity of coal-based nano-carbon hydrogen units and photovoltaic units can be obtained.

[0117] According to the calculation formula obtained above, the objective function is obtained by comprehensively considering electricity (installation cost, operation cost and income, etc.), heat (heat generated by cogeneration units and sold for profit), carbon emissions (carbon tax cost) and electrolytic aluminum production benefits in a typical photovoltaic day. The objective function can be shown as follows:

[0119] Among them, f1 can be used to represent the system installation cost, operating cost and revenue, f2 can be used to represent the profit from the sale of heat generated by the cogeneration unit, f3 can be used to represent the carbon tax cost, and f4 can be used to represent the cost of electrolytic aluminum load fluctuations.

The remaining coefficients can be obtained according to the calculation formula involved above. In addition, the carbon cost consumed by the nano-carbon hydrogen fuel unit has been included in the operating cost of the nano-carbon hydrogen unit and does not need to be considered separately.

[0123] Alternatively, the profit from selling heat produced by the CHP unit can be calculated by the following formula:

[0124]

[0125] Among them, c heat Can be used to express the unit revenue factor for heat sales.

[0126] Alternatively, the cost of the carbon tax can be calculated as follows:

[0127]

[0128] Among them, c C It can be used to represent the carbon tax cost of emitting unit mass of carbon dioxide; c coal It can be used to express the mass coefficient of carbon dioxide produced by coal combustion, which can be obtained according to the chemical equation; m coal Can be used to indicate the mass of coal consumed; It can be used to express the ratio of total heat to electricity when coal is burned; c al It can be used to express the mass coefficient of carbon dioxide emitted by producing a unit mass of aluminum through electrolysis, which can be obtained according to the chemical equation; m al Can be used to express the mass of aluminum produced by electrolysis.

[0129] Alternatively, the cost of electrolytic aluminum load fluctuation can be calculated by the following formula:

[0130]

[0131] Among them, P al Can be used to indicate real-time power, Can be used to indicate rated power, c delta Can be used to represent penalty coefficients. For example, according to the existing structure, the rated power It can be taken as 100 (unit: MW), which is only used as an example here and is not specifically limited.

[0132] Furthermore, for the objective function, the following constraints are set: power balance constraint, nano-hydrocarbon unit constraint, load constraint and installed capacity constraint.

[0133] The power balance constraint condition can be expressed as follows:

[0134] P al，t =P pv,t +P gt,t (13)

[0135] The constraints of the nano-hydrocarbon unit may include: output constraints and ramp rate constraints. The output constraints may be as shown in the following formula (14), and the ramp rate constraints may be as shown in the following formula (15):

[0136] P gt_min ≤P gt,t ≤P gt_r (14)

[0137] r down ≤P gt,t -P gt，t-1 ≤r up (15)

[0138] Among them, r up It can be used to indicate the maximum upward ramp rate of the nano-hydrocarbon unit, r down It can be used to indicate the maximum downward climbing rate of the nano-hydrocarbon unit.

[0139] The load constraint condition can be expressed as follows:

[0140] P al,min ≤P al，t ≤P al,max (16)

[0141] The installed capacity constraint conditions may include: the installed capacity constraint conditions of the nano-carbon hydrogen unit and the installed capacity constraint conditions of the photovoltaic unit. The installed capacity constraint conditions of the nano-carbon hydrogen unit may be as shown in the following formula (17), and the installed capacity constraint conditions of the photovoltaic unit may be as shown in the following formula (18):
