The development of high and new technology and new industries makes the demand for zinc chloride strong and green upgrade is the general trend! [zinc oxide Forum]

SMM: at the ninth green zinc salt and zinc oxide industry summit forum held by SMM in 2021, Ma Ruixia, executive vice president of Weifang Hengfeng Zinc Industry Co., Ltd., said that the output of zinc chloride in China is developing rapidly. China began to export in 1964, and there is a big gap in product quality compared with foreign manufacturers, such as electronics industry and medical zinc chloride. The average price of imported products is more than 40% higher than that of China's export zinc chloride. Although China is the largest producer of zinc chloride in the world, zinc chloride production enterprises are uneven, and most of them have small production scale and scattered capacity. Therefore, there is a lack of unity and coordination in the development of high-grade zinc chloride products. With the development of national high and new technology and the rise of new industries, the demand for high-grade zinc chloride is strong, and it is a process of sustained growth.

The "13th five-year Plan" period (2016 Muhammad 2020) is an extraordinary historical period for China's economic and social development. Novel coronavirus's epidemic situation is seriously impacted, the trade war limit pressure is exerted, and the pressure of safety and environmental protection is unprecedented. The zinc chloride industry is facing an unprecedented complex environment, unprecedented difficulties and unprecedented challenges. Especially in the United States and others in response to the impact of the COVID-19 epidemic, the long-term implementation of quantitative easing monetary policy, the prices of bulk energy resources have risen sharply, the production and operating costs of China's chemical enterprises have increased rapidly, and the profit space has shrunk. Competitiveness is further weakened.

The total energy consumption of the industry continues to grow, and the total energy consumption exceeds 600 million tons for the first time in 2019. In particular, the problem of hazardous waste management in the industry is prominent, with large production, many types, complex components and difficulties in treatment and disposal. At the same time, the water use system of the industry is complex and water consumption is large, and wastewater treatment has become a bottleneck perplexing the development of the industry for a long time. The high concentration of refractory organic wastewater and high concentration saline wastewater in the industry requires high technical requirements for reducing discharge and harmless disposal. Pollution control can not achieve results for a long time, and treatment is more difficult, which has become one of the difficult problems that must be overcome by great efforts in the development of the industry.

Green upgrade is the trend of the times

The 19th CPC National Congress has listed the principle of harmonious symbiosis between man and nature as the basic strategy of socialism with Chinese characteristics in the new era. The chemical industry, as the pillar industry of the national economy, energy conservation and environmental protection, pollution discharge, technical research, implementation of circular development leading plan, promote the circular link of production and life system, and speed up the utilization of waste resources. Environmental safety has always been the top priority throughout development.

To break the traditional industry image of "high energy consumption and high pollution" and upgrade to "green" is the general trend, which is the direction of joint efforts of the global zinc chloride industry. Zinc chloride enterprises should join the tide of the development of the green chemical industry, continue to adhere to the ingenuity of intelligent manufacturing and green innovation, and continue to forge ahead on the development road of pioneering and optimizing innovation. It is necessary to constantly strengthen the main responsibility of green development, establish and complete the green development management system, realize the spiral rise of the green development level of zinc chloride enterprises, and contribute to the construction of China's intelligent and national industrial brands. Promote China's zinc chloride industry to move towards the middle and high end of the global value chain, and cultivate world-class advanced manufacturing clusters. " This is not only an important requirement of the 19th CPC National Congress for the establishment of a modern economic system, but also a successful practice of economic development in developed countries. In the current situation, zinc chloride enterprises how to take the road of high-quality development in a targeted and down-to-earth way has become the focus of attention of all parties in the industry.

Green industry, green park

We will promote the recycling production transformation of existing industrial parks and the design of the industrial chain of pre-circular economy in newly-built industrial parks, and realize the cascade utilization of energy, the recycling of water resources, the exchange and utilization of waste, and the saving and intensive use of land. As of May 2021, 57 chemical parks have carried out recycling transformation with the support of the Industrial Development Department of the National Development and Reform Commission, and 33 chemical parks have been awarded the "National New industrialization Industry demonstration Base" by the Ministry of Industry and Information Technology. Twelve parks were selected into the "Green Chemical Park" list, and 8 parks were selected as "Green Chemical Park" (creation) units. 64 chemical parks signed the global charter of responsible care, and 8 parks spontaneously set up responsible care working organizations.

Establish a perfect enterprise environmental protection system

Specifically, we should pay attention to the prevention and control of the risk of environmental pollution: analyze and study the possibility of the risk of environmental pollution. In the process of recognizing and paying attention to the risk assessment, the various factors of environmental pollution are comprehensively evaluated and analyzed, and then the corresponding management plans and rectification measures are made. At the same time, for the risk analysis of major environmental impact factors or hazard sources, emergency risk plans and prevention and control should be initiated, which can not only effectively protect the environment, but also better ensure the safety of people's lives and property.

Establish a dynamic management system of enterprise environment: enterprises should take green development as their new development goal, and be able to establish a perfect dynamic management system.

Establish a comprehensive environmental protection management assessment and incentive management system: through a perfect evaluation and assessment system, we can comprehensively evaluate the environmental indicators of the enterprise, the energy consumption of equipment, the discharge of waste, the responsible party of pollution accidents, and so on. At the same time, score assessment is carried out according to these contents and serve as an important basis for the final enterprise assessment.

Strengthen Scientific and technological Innovation and promote Green Development

Strengthen scientific and technological innovation to protect the green development of zinc chloride enterprises. Scientific and technological innovation is the only way for development, and it will also become an important guarantee for the green development of zinc chloride enterprises. We will vigorously develop environmental protection and clean technologies, develop and apply new technologies, new processes and new products with low investment, low consumption, low pollution and good benefits, reduce and reduce energy consumption of raw materials, and achieve reduction, resource utilization and reuse of pollutants. The specific measures include:

It is necessary to be able to seize the commanding heights of international and domestic technological innovation. Develop environmentally friendly processes and develop environmentally friendly products. Combined with the competition requirements of the development of new products in the market and the industrialization of technological achievements, enterprises have increased their investment in technological progress every year, and have developed a large number of new technologies, processes and products that are conducive to saving energy and reducing consumption, improving product quality and enhancing market competitiveness. It is also beneficial for enterprises to protect the environment and control pollution.

National laws and regulations and relevant policies strongly encourage the recycling of resources, such as the Law on the Prevention and Control of Environmental pollution by solid waste, which clearly requires the full recovery and rational use of solid waste. There are many valuable components in different types of hazardous wastes. if they can be recycled and comprehensively utilized through reasonable and environmental protection measures, it will not only reduce the pressure of hazardous waste disposal, but also turn waste into treasure. to obtain objective economic benefits. Waste can be converted into valuable resources as long as it is economically and technically feasible.

Green system

National incentive policy

In recent years, the state has issued a number of policies and measures to encourage the development of recycling of renewable resources. Including the Circular of the State Council on issuing the Development Strategy and short-term Action Plan of Circular economy, the Circular on Investment and financing policies and measures to support the Development of Circular economy, the opinion of the State Council on speeding up the Development of Energy Saving and Environmental Protection Industry, and the Circular of the State Council on doing a good job in Building an economical Society in the near future. the circular has made corresponding provisions on the development of recycling of renewable resources.

However, the traditional zinc chloride production process has some disadvantages, such as waste gas and waste water discharge, noise pollution, insufficient utilization of resources and so on. Zinc chloride is called zinc ash because most of it is gray or scattered slag, which is a kind of hazardous waste. Zinc-containing waste is toxic, if discharged at will, it will cause great harm to the environment and human health.

In addition, the production of zinc chloride is accompanied by a large amount of waste water, which contains a large amount of zinc chloride, alcohols, and a small amount of esters and ketones, and the loss of a large amount of zinc chloride causes pollution and leads to a waste of resources. however, because zinc chloride requires high purity, the waste water can not be directly separated and reused. How to remove organic pollution from water and achieve high purity extraction of zinc chloride has become a difficult problem for the industry.

After a series of process improvements, the improved zinc chloride production equipment has the following advantages compared with ordinary equipment:
