On October 11-15, the 15th Meeting of the “CBD COP15” of the “Cybersecurity of Biological Multivariate” was held in Kunming. President Xi Jinping attended the Leader’s Summit on the 12th and delivered a purpose speech. He emphasized that people and nature should coexist harmoniously, and their birth environment is both natural and economic wealth. It is related to the potential and backbone of economic and social development. We must accelerate the structure of green development. She stood up and walked down the stage. Methods, promote the dual wins of economic development and environmental protection, and build a Earth homeland that cooperates with the environment. Climate change is a global problem facing humans. With carbon dioxide emissions from various countries, the temperature room gas has soared and the life system has been threatened. Under this scenario, countries around the world have reduced their temperature gas by global agreements, and my country has thus proposed the targets of carbonization peak and carbon neutrality.

Carbon neutrality and energy consumption dual control are applied, and production of high energy consumption and high carbon rankings is limited

Whether it is the green development method mentioned in the COP15 meeting, or the energy reduction request mentioned in the dual carbon targets, all touches carbon dioxide emissions. The non-ferrous metal smelting industry, as a major industry for carbon emissions, is currently receiving attention from the authorities and markets.

The preliminary statistics of the China Nonferrous Metal Industry Association: The total carbon dioxide emissions of my country’s nonferrous metal industry in 2020 are about 65 million tons, accounting for 6.5% of the country’s total emissions. Among them, the carbon dioxide emissions of electrolytic aluminium are about 42 billion tons, ranking first in the nonferrous metal industry.

In August this year, the National Development and Reform Commission prepared the “Barometer for the completion of dual-control targets for energy consumption in various regions in the first half of 2021″ based on the dynamic consumption situation in various regions in the first half of 2021”. Among them, the energy consumption intensity of the nine provinces (regions) in the first half of the year was less than the bottom. Is this dream true or false? Do you think it is the stone for the purpose of the knowledge competition? Reduced and rose, and there are 10 provincesSugar daddyThe energy consumption intensity reduction rate did not reach the progress request.

Information from China Aeronautics Network shows that the power consumption of the electrolytics industry is very high.Manila escort is large. Due to the differences in production technology installation levels, the electricity consumption of each production enterprise for each production of one aluminium is relatively large. Today, the large number of domestic aluminum alloys is between 14,000kwh-16,000kwh. my country’s main electrolytic aluminum alloy production areas, such as Qinghai, Ningxia, Xinjiang, Xi, Guangxi, Yunnan, etc. appeared in the first-level warning list. They all faced strict dual-control requests for energy consumption. Restriction in departmental areas has become a common phenomenon. This has undoubtedly had a practical impact on the production of electrolytic ash. As shown in Table 1.

The department has issued a notice on the national dual control policy. Escort manila

On the evening of September 16, Yunxiang Co., Ltd. announced that since May 2021, due to tight power supply, industrial enterprises in Yunnan Province have implemented orderly electricity use, and the electricity consumption burden of companies and subordinate enterprises has dropped significantly. As of the date of issuance of notice restrictions, the company has reduced the capacity of electrodischarge aluminum alloy production by about 770,000 tons. On the evening of September 17, Sugar baby issued a notice to announce that due to the tightening of power supply, the Sugar manila will be issued a notice. Since the 10th, Yunnan Electric Network Infinite Responsible Company (hereinafter referred to as “Yunnan Electric Network”) has implemented orderly power supply to domestic electrodischarge enterprises in Yunnan Province. The total supply and supply load of Yunnan Shenhuo Aluminum Co., Ltd. (hereinafter referred to as “Yunnan Shenhuo”) has dropped significantly. Since the hoped land has been suspended for 200,000 tons, its production capacity has dropped to 550,000 yuan. daddyTundes, the second series and third section 150,000 were not started as scheduled.

According to the Baichuan Statistics, as of September 30, 2021, the useful production capacity of China’s electrolytic electrolytics was 45.422 million tons, with a starting rate of 38.271 million tons, and an operating rate of 84.26%.

High energy-consuming aluminum materials industry attracts attention. The selection of original data of photovoltaic industry has led to thoughts

In the photovoltaic field, Sugar daddy aluminum materials are importantly used in the two parts of photovoltaic component frames and brackets. According to the futures date, the size of the photovoltaic frame is importantly affected by the total size of the silicon wafer battery in the assembly. Refer to the important products and sizes of the component Longtou enterprise, and use them as the dimensions of the aluminum frameAs shown in Table 2. There are three types of aluminum alloys used in photovoltaic frames: 6061, 6063 and 6082, with density of 2.75g/cm3, 2.69g/cm3 and 2.71g/cm3 respectively. In fact, Chen Jubai does not quite meet the standards of Song Wei. The aluminum consumption of the volts is calculated according to the formula, the cross-sectional area × component size length & width × alloy density, and finally the aluminum consumption of the single GW photovoltaic frame is about 9,000 to 11,000.

Photovoltaic power stations can be divided into distributed photovoltaic power stations and centralized photovoltaic power stations according to the construction method. It can be seen from the construction of the station, the material characteristics of the aluminum alloy data and the market application that domestic aluminum alloy brackets are more used in distributed photovoltaic stations. Refer to the Sugar daddy Planning and Design Institute of Nuclear Power in 2016 daddyThe Economic Comparison Analysis of Gold Stents and Steel Stents” is based on a 20MWp distributed photovoltaic power generation project in Huainan. The project has a basic wind pressure: 0.35kN/m2, and the basic snow pressure: 0.60kN/m2. The design application life of the stent is 25 years. Sugar is adopted. baby uses a single crystal silicon 270wp assembly, the component size is 1650×990×40mm, each assembly is 19.5kg, and the 44-piece assembly is a array, using a fixed type, and the bracket is obliquely angular.The degree is 23°. All battery assembly brackets are composed of columns, inclined beams, inclined shafts, slats and connecting accessories. The important material of aluminum alloy is 6063-T6. Sugar daddy uses yang oxidation treatment, and the connecting bolts and nut pads are made of C-level popular bolts. According to the calculation, the aerosol consumption of a bracket used in a single GW distributed photovoltaic station is about 19,000 tons, as shown in Table 3.

According to the data of the carbon buying and selling network, if a 13,500kwh of aluminum is consumed, the firepower power generation is equivalent to emitting 13,000 carbon dioxide, as shown in Table 4. According to the data of the intermediate data of non-ferrous information, the output of photovoltaic profiles (including photovoltaic component edge frames and bracket p TC:
