\u3000\u3000 “In order to consolidate the achievements of circular transformation of the park, we actively develop green industry, join the green alliance of national development zones, and take the first special action of energy conservation and carbon reduction in the Corps, guide enterprises to optimize and transform industrial kilns and production equipment, guide enterprises to actively make comprehensive utilization of industrial silicon kiln tail gas, reduce carbon emissions, and actively promote green and low-carbon development zones Carbon transformation and high-quality development. ” On March 2, Wang Jigang, head of fixed asset investment post of economic development center of Shihezi Development Zone Management Committee, said in an interview with reporters.
In recent years, Shihezi Development Zone has always paid attention to the green transformation and development of the park, adhered to classified guidance, implemented policies according to enterprises, and made great efforts around the construction of circular industrial chain, comprehensive utilization of waste, construction of public service facilities, so as to guide and drive the green circular and low-carbon transformation and development of enterprises in the park.
During the 13th Five Year Plan period, the comprehensive energy consumption per 10000 yuan output value in Shihezi Development Zone decreased by 36%, the total emissions of sulfur dioxide and nitrogen oxides decreased by about 18% respectively, and the comprehensive utilization rate of industrial solid waste increased from 82% to 93%; The reuse rate of industrial water increased from 93.4% to 45.4%; The industrial chain relevance of circular economy in the park has increased from 30% in 2013 to 64.9% in 2020. The effect of circular economy and green development is obvious.
In 2021, Shihezi Development Zone successfully passed the final acceptance of the state and became the first batch of demonstration pilot parks of circular transformation of Xinjiang production and Construction Corps.
In the interview, you can feel the atmosphere of green industry everywhere Tianshan Aluminum Group Co.Ltd(002532) Co., Ltd. invested 580 million yuan to carry out ultra-low emission in-depth treatment and transformation of enterprise electrolytic flue gas desulfurization, and added wet desulfurization process on the basis of the original dry treatment to double purify the tail gas, so as to reduce the particulate matter in the tail gas emission to the ultra-low national emission standard. This process upgrade alone can reduce about 3000 tons of sulfur dioxide and about 30 tons of hydrogen fluoride every year.
Deng Mingshun, deputy director of Tianshan Aluminum Group Co.Ltd(002532) flue gas purification advanced treatment center, said: “At present, our desulfurization index – sulfur dioxide has been reduced by two-thirds from 60-80 mg / m3 to less than 30 mg / m3 in our original dry purification progress. Hydrogen fluoride is now basically in a zero state, because wet desulfurization is designed to have an outward flow of 20 m3 per hour, but through our current process optimization, I After being treated, the waste water is returned to our desulfurization tower for use. It goes round and round, saving about 480 cubic meters of water every day. “
The new desulfurization process not only meets the high-efficiency desulfurization of flue gas, but also ensures that the quality of desulfurization gypsum reaches more than 90%. Through the solid waste treatment process, after crushing, pulping and chemical reaction treatment, the solid waste is filtered into harmless fuel, which is supplied to the generator set for combustion, recycling and turning waste into treasure.
Lu Mingyuan, director of Tianshan Aluminum Group Co.Ltd(002532) solid waste workshop, said: “After the hazardous waste is put into operation last year, we can make a comprehensive use of the hazardous waste. The total investment is about 40 million tons of solid waste. After the hazardous waste is put into operation last year, we can make a comprehensive use of the hazardous waste. We can produce about 19 million tons of solid waste every year.”
Xinjiang West Hoshine Silicon Industry Co.Ltd(603260) Co., Ltd. actively brings gratifying benefits to the enterprise through independent research and development of new technologies and energy conservation and consumption reduction. Meng pengpeng, a post-90s generation, and his colleagues developed the automatic power distribution project of industrial silicon furnace based on DCS control system, realizing the remote operation of power distribution, which is also unique in the industrial silicon industry. You Zhilin, the dispatcher of the fourth branch of Xinjiang western Hoshine Silicon Industry Co.Ltd(603260) Co., Ltd., said: “when I came to 2012, all the power distribution in the operation distribution room was carried out manually. In 2019, the company fully implemented automatic configuration, automatic power distribution and mechanized pushing. The overall past few years have been almost a qualitative leap, and the overall furnace life cycle has been extended by 200%.”
Zhu Zhiqiang, deputy general manager of Shihezi Park of Xinjiang West Hoshine Silicon Industry Co.Ltd(603260) Co., Ltd., said: “Hesheng is a circular economy industrial park, so all solid wastes produced in production are fully recycled. More than 100 million yuan is invested to recycle the silicon slag and fly ash produced by power plants. In addition, in terms of environmental protection, more than 200 million yuan is invested to desulfurize industrial silicon, greatly reducing the emission concentration and total emission of pollutants. In the next step, energy-saving transformation will be carried out for industrial silicon production links of enterprises, including furnace type, so as to further reduce energy consumption and reduce energy consumption. “
During the “14th five year plan” period, Shihezi Development Zone takes energy conservation and carbon reduction as an important starting point to accelerate the construction of ecological civilization and promote the high-quality development of the park. It adheres to building an ecological district and manufacturing a strong district, actively responds and seeks change, completes the “addition” of facility investment and “subtraction” of carbon emission, and jointly promotes the green transformation of the park.
Wang Jigang said: “we have successfully applied for a central fund of 130 million yuan to improve the infrastructure construction of the Development Zone, encourage small circulation within enterprises, medium circulation among enterprises and large circulation between parks, and build a circulation demonstration of the development zone from upstream to downstream as a whole.”
