With the proposal of my country’s “carbon peak in 2030 and carbon neutrality in 2060″, it will have a revolutionary impact on new energy, chemical industry, construction, environmental protection and other industries. The National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Finance, and the Ministry of Science and Technology jointly issued the “Guiding Opinions on Expanding Investment in Strategic Emerging Industries to Cultivate and Expand Growth Points of New Growth Points”. The inclusion of energy and so on to encourage development indicates that the new energy era with solar photovoltaic power generation as the main driving force has come.
The research shows that the cumulative installed capacity of global photovoltaics in 2020 will be 725GW, and the cumulative installed capacity of global photovoltaics will reach 14,000GW in 2050. From this, it is estimated that the growth rate of the photovoltaic industry from 2020 to 2050 will be 10.4%, and the growth space of the industry is extremely high. Photovoltaic emission reduction projects can sell their carbon dioxide emission reductions in the national carbon market to obtain economic benefits.In the photovoltaic industry chain, quartz sand resources are located upstream and are the basic raw materials. According to the national strategic plan of “carbon peaking and carbon neutrality”, the photovoltaic industry will lead to explosive development, and the demand for low-iron quartz sand is expected to grow at a rate of more than 30% per year. There will be bottlenecks in the supply of low iron sand raw materials. Because the reserves of high-quality quartz sand resources are extremely limited, and medium and low-quality quartz sand resources are abundant, to solve this supply problem, it is imperative to develop quartz sand purification and impurity removal technologies and improve the quality of quartz sand.
There are various impurities in quartz sand raw materials, such as Fe, Ti, Al, K, Na, Ca, Cr, etc., and the most harmful in photovoltaic glass production is iron impurities. The states of Fe2O3 in quartz sand are: associated There are several forms of iron impurities in clay and accompanying heavy minerals, argillaceous and thin-film iron on the particle surface, iron impurities in silica sand particles and primary inclusions distributed in crystals. In the process of quartz sand processing and production, appropriate iron removal technology and equipment should be selected according to the properties of the ore.
In recent years, Huate Magneto has carried out a lot of process research and equipment research and development in the purification and decontamination of quartz sand, and successfully made low-iron photovoltaic sand from medium and low quality quartz sand, sea sand and river sand after decontamination. Large quartz sand bases and ports (imported sand) have been successfully applied.
It is believed that with the carbon peak and the continuous advancement of the carbon neutralization process, my country’s photovoltaic industry will usher in a golden period of development. The development of the photovoltaic industry will also become a “big trend” in the future.
Huate quartz sand purification application case
01
The quartz sand concentrator customized Huate LHGC2500 vertical ring magnetic separator to completely replace the flotation purification process in the original process.
02
The project has an annual output of 500,000 tons of quartz sand. The 2745 ball mill production line (CTN1230 permanent magnet drum ➕LHGC2500 vertical ring) is used to remove mineral impurities in the quartz sand and obtain high-purity quartz sand with particle size and impurity content that meet the requirements.
03
The project has an annual output of 1 million tons of quartz sand, using 4 LHGC2500 oil-water composite cooling vertical ring high gradient magnetic separators + 4 SGB strong magnetic plate magnetic separators, the purification effect is good, and the quality index of the obtained fine sand is excellent.
04
The project has an annual output of 500,000 tons of quartz sand, and is the second 2745 ball mill production line in the project supporting 2 LHGC2500 vertical ring high gradient magnetic separator production lines.
