Old, big, thick and black are the impressions left by the Dazu industry on the outside world.

This image is now being rewritten. The reporter recently found out in Dazu that the Dazu industry is turning gracefully to move toward a recycling economy with high technological content, energy saving, environmental protection, and low carbon.

The emerging industries with high technological content have risen in the past. The industries are dominated by traditional hardware, coal, cement, and stone. Since Zhongshun Solar's national high-tech key project was settled in 2010, Dazu has taken steps to develop new industries.

Zhongshun Solar Energy Co., Ltd. is an energy-saving company introduced by Dazu. This company used its national high-tech key research projects to build a concentrated photovoltaic research center and a tracking photovoltaic system demonstration base, a tracked flat photovoltaic assembly system, and a concentrating photovoltaic assembly center in Dazu County.

Experts in the industry have stated that the technology of tracking the sun with the sun is the core of the concentrated photovoltaic power generation industry. This technology mainly reduces the use of solar cells to increase the efficiency of light collection, thereby significantly reducing manufacturing costs. At present, the world-accepted technology that is difficult to break with the device must meet the following three conditions at the same time: First, high precision. It is required that the sun leans on the solar cell every day and does not exceed 0.5°, and there is no cumulative error. The second is high reliability. Requires 20 years of use once installed. The third is to lower costs.

According to reports, Zhongshun has made breakthroughs in this core technology through independent research. The self-designed and manufactured high-power concentrator photovoltaic modules have the features of high photoelectric conversion efficiency, mature domestic components, and easy industrial production. Based on this core technology, the solar power station system can reduce the construction cost per kilowatt. To more than 9000 yuan, the cost of the fixed-plate solar power station is 50% lower than that of the current domestic tradition, which means that the cost of solar power will be reduced to 0.6-0.8 yuan/degree.

Now, Zhongshun Solar has cooperated with Sichuan Hanlong Group to do solar power generation equipment industry in Dazu, and has signed 15 billion yuan orders with European countries. If the power generation equipment is widely used, this industry will bring 20 billion, 30 billion annual output value.

Domestic advanced technology to replace the small electroplating factory Dazu small hardware can not be separated from electroplating, over the years, in Dazu County developed more than 40 small electroplating factories with Dazu hardware support, these small electroplating plants become the biggest source of pollution in the Dazu industry.

In transforming the mode of economic development, these more than 40 small electroplating factories will all be closed by the end of July this year.

Closed a small electroplating factory, hardware matching electroplating?

In the Dazuo Post Pavilion Industrial Park, a new environmentally friendly electroplating park covering 120 acres is under construction. This electroplating park is a standardized electroplating factory newly established by the Guangdong New Daxie Group Technology Co., Ltd. with a current investment of 180 million yuan. At the same time, the county also set up a pickling center in Longshui to fundamentally solve the pollution problems brought by the hardware industry.

Circular economy industry chain gradually formed from small hardware to large hardware, from traditional hardware to modern hardware, and the Dawu hardware industry, which has a history of over a thousand years, is undergoing butterfly transformation.

In the Dazu Industrial Park, a circular economy industrial park built on traditional hardware has been launched. This circular economy industrial park covering an area of ​​2 square kilometers is currently constructing 400,000 tons of recycled lead.

Last year, Hongyuan Metals, a lead smelting company in Dazu County, cooperated with Italy’s Melloni, the most advanced lead smelting technology in the world, to build a 200,000-ton-agricultural lead production project. Subsequently, Jiangsu Chunxing Group, the largest lead smelter in China, is also building a recycling lead production project with an annual output of 200,000 tons in the circular economy industrial park. Both of these companies are purchasing waste batteries and extracting lead from them to produce automobiles, mining batteries, and lithium batteries. After the completion of the two major projects, it will centralize the acquisition of used batteries in the entire southwest region and form an annual output value of nearly 20 billion yuan.

In the Dazu hardware industry, the scrap metal market is also an important part of it. At present, the annual acquisition of scrap metal has reached 1 million tons, plus a large amount of scrap metal will be produced in the hardware industry. Scrap metal will become a surplus resource. Dazu County introduced Juhang Company to use scrap metal to produce alloy steel, and then use alloy steel to produce steel components to form a recycling industry chain.

At present, 9 production lines of the first phase of Juhang Company's steel construction project have been put into production, and eventually 50 production lines will be built, with an annual output of 3 million tons. With the extension of products, the annual output value of this industrial chain will reach 30 billion yuan.
