Continue to tackle key problems and stimulate new vitality through scientific and technological innovation
"Now, conch group is not only successful in the cement industry, but also in the environmental protection industry." A Zhejiang cement enterprise executive commented on Anhui conch group. In the industry, in order to ensure the reliable quality of some key engineering projects, which bidding enterprise can get conch cement will also become one of the bonus factors before bidding.
The reporter recently went to Anhui conch group to visit the password behind its industry development and innovation.
Gao dengbang, party secretary and chairman of Anhui conch group, said that at the beginning of his transfer from Wuhu Municipal Party Secretary to conch group, he was regarded as a "layman" by the outside world and the market to take over the class of "old cement", and the stock price of conch cement was once reduced from 15 yuan and 16 yuan to more than 13 yuan.
Gao dengbang said that, on the one hand, there are many things to learn to take over the class of "old cement". On the other hand, he had worked in a large state-owned enterprise for 15 years, and he was no stranger to enterprise management, production and operation“ We handed over the answer sheet with real enterprise development achievements. The operating efficiency, operating efficiency and operating quality have been greatly improved. The stock price has increased steadily in recent years and is currently stable at more than 50 yuan, reflecting that the market is optimistic about conch. "
Behind the outstanding achievements is the vitality brought by conch's continuous tackling of key problems and scientific and technological innovation.
Gao dengbang told reporters that conch group has been tracking the world's most cutting-edge technologies and exploring carbon emission reduction in the cement industry through process improvement, energy consumption control, new technology and new energy application. In October 2018, the world's first 50000 ton annual "carbon dioxide capture and purification demonstration project for cement kiln flue gas" (CCS) was built in Wuhu Baimashan cement plant, with an investment of more than 55 million yuan, which can produce carbon dioxide products with 99.9% industrial purity and 99.99% food purity at the same time. At present, Baimashan cement plant is planning to convert carbon dioxide products. The dry ice project with an annual output of 3000 tons will be completed in January 2020, further extending the carbon dioxide recycling industrial chain.
The industry believes that the project is a landmark project of the world cement industry, which effectively solves the problem of disposal and utilization of carbon dioxide generated in the production process of the cement industry, opens up a new journey of environmental governance in the cement industry, and further lays the technical foundation for low-carbon and green development of the building materials industry.
Through the research on the improvement of the comprehensive energy efficiency of the production line, the conch has implemented the technical transformation, the standard coal of the system has been reduced by about 10kg, and the comprehensive power consumption of cement clinker has been reduced by about 10 degrees. According to the annual output of 2 million tons of clinker of a production line, the annual carbon dioxide emission has been reduced by about 67500 tons.
In October 2020, conch completed and put into operation a technical transformation project with an annual alternative fuel of 300000 tons, which can consume 260000 tons of rice straw, rape rod and bark every year, save 75000 tons of standard coal and reduce 200000 tons of carbon dioxide every year. The waste heat power generation system and oxygen enriched combustion system of cement clinker production line developed and implemented by conch can reduce about 11 million tons of carbon dioxide per year.
In addition, the conch investment company established by conch group has laid out industries such as photovoltaic, wind power generation and energy storage. By the end of 2020, the installed capacity is 130 MW, the cumulative power generation is 279 million kwh, and the carbon dioxide emission reduction is about 250000 tons.
The story behind the "change of command" of industry leaders
Five years ago, the change of the chairman of conch group once attracted great attention from the cement industry and the capital market.
The Anhui provincial Party committee and the Anhui provincial government originally decided to arrange for conch to be listed on the list. One of the clear tasks is to bring conch into the world's top 500 during the 13th Five Year Plan period“ We will achieve the goal of entering the world's top 500 for the first time in 2019, ranking 441 and 367 in 2020. The sales revenue of conch has quadrupled, the profit has increased steadily from about 10 billion yuan, and has been stable at more than 40 billion yuan for three consecutive years. " Gao dengbang said.
The road to success has never been smooth. At the end of the 12th Five Year Plan, the operating performance of the national cement industry fell sharply, and conch faced the same dilemma.
Gao dengbang told reporters that the performance decline at that time was an industry wide adjustment. After a period of rapid development, resources, environment, market, talents, technology and management need to be adjusted. After a short adjustment, the benefit of conch doubled. This is actually a cumulative causal effect, which is the basis of predecessors. It has been well laid and the production capacity and quality are relatively high“ Why adjust? With China's economic transformation, there is a deviation between the original growth mode of cement industry and resource endowment structure and social demand, which is mainly reflected in environmental protection, forming a huge risk exposure. "
"To converge this exposure is to solve the contradiction between enterprises and the environment and promote energy conservation and emission reduction." Gao dengbang said that conch has continuously introduced advanced technology from a number of foreign enterprises and spent billions of yuan every year to transform the original production line, which has achieved remarkable results, making a balance between our enterprise production and environmental protection. In 2020, with the superposition of epidemic situation and flood situation in Anhui, the production capacity utilization rate of conch cement furnace exceeded 90%, far higher than the industry average of 60%. The role of advanced production capacity has been reflected in the market competition, and the economic benefits have been greatly improved.
In terms of intelligence, in 2018, conch group completed the whole pepper conch intelligent factory. After putting into operation, the comprehensive operation rate of the two production lines reached 94.26%, and the company's labor productivity increased by 19.96%. In addition, conch has also developed and applied mine car driverless technology in some mines. Through a series of "scientific and technological empowerment" and "digital empowerment", the advanced technology of conch group is systematized and standardized, and some original technologies such as carbon capture and development and utilization are extended to more fields.
Explore the environmental protection attribute into a "purifier" in the city
Gao dengbang said that we were not so clear about the positioning of the "purifier" of the urban environment at the beginning, but as we did, the environmental protection attribute of the cement industry was discovered. We found that the cement industry and the environmental protection industry are not antagonistic, and we are part of the environmental protection industry. The more to the later stage of urbanization and industrialization, the stronger the environmental protection attribute of cement industry. The future direction is to make the cement plant become the standard configuration for industrialization and urbanization.
In the early stage, conch developed and applied the low-temperature waste heat power generation technology of cement kiln, which solved 60% of the power consumption of cement enterprises and was written into the standard for the construction of cement plants in China; Later, conch deeply integrated the modern cement industry with the green industry, used the cement kiln for collaborative disposal of domestic waste, solid waste and hazardous waste, and first applied the cement kiln collaborative treatment of urban domestic waste project in Tongling City, with a cumulative treatment of 1285000 tons“ The treatment capacity in 2020 is 170000 tons. If the kiln is not opened for two weeks, the local urban waste treatment will become a big problem. " Fang Yuan, assistant general manager of conch group, said.
It is reported that the cement kiln has large hot melting capacity and high temperature. The temperature of the firing zone can reach 1700 to 1800 degrees Celsius. The kiln can meet the needs of full combustion of hazardous wastes. The organic part is burned directly, and the inorganic heavy metal salt is degraded and solidified into the clinker crystal, which can truly achieve harmless treatment. Based on the unique advantage of cement kiln, conch group has built the first "demonstration project of collaborative disposal of solid waste by cement kiln" in the industry. The project closely combines cement production with solid waste treatment, uses the heat energy generated by incineration of solid waste as cement production, and uses the "residue" after incineration as auxiliary raw material of cement, so as to achieve zero emission treatment of solid waste and open up a new mode of energy conservation and environmental protection. Through technical transformation, conch shall be disposed according to the safe proportion of national standards. The mixing of hazardous waste shall not exceed 5%, and the general solid waste can reach 10% to 15%. According to the rough calculation of the national annual cement clinker output of 2 billion tons, 200 million tons and 300 million tons of waste can be treated every year.
According to Fang Yuan, at present, conch has successfully promoted 106 environmental protection projects in 20 provinces, autonomous regions and overseas, and built 36 domestic waste treatment projects and solid and hazardous waste disposal projects using cement kilns. After all the planned projects are completed, it will form a disposal scale of 10.62 million tons of domestic waste and 4.43 million tons of solid and hazardous waste, truly transforming the traditional cement industry into a green industry, Become an important part of the industrial chain of circular economy.
Gao dengbang told reporters that if conch began to enter the environmental protection industry due to the passive response of external pressure, with the establishment and maturity of conch technology innovation system, these advanced technologies are rooted in the enterprise and form the internal evolution ability. These internal capabilities have repeatedly improved the environmental protection and emission reduction potential of conch and led the world.
The average emission concentrations of key indicators such as sulfur dioxide, nitrogen oxides and particulate matter of conch group are far lower than national standards and much lower than foreign standards such as European standards. For example, the national standard for dust emission is 30 mg / m3, and conch has been reduced to 10 mg / m3; The national standard for NOx emission is 400 mg / m3, and conch is reduced to less than 200 mg / m3; The national standard for sulfur dioxide emission is 200 mg / m3, and the lowest level of conch has been reduced to 50 mg / m3.
The continuous development of technology has blurred the original industrial boundary. In the future, the main value of cement kiln is not only the production of cement, but also the collaborative treatment of urban domestic waste and industrial waste. Generally speaking, there are hundreds of tons of garbage in a county every day, thousands to thousands of tons of garbage in a medium-sized city every day, and there are a large number of wastes, surface polluted soil and polluted river sludge in the process of industrialization. Other methods have high cost and poor effect. And put it in the cement plant, the effect is better.
Gao dengbang said that during the "14th five year plan" period, the overseas production capacity of conch will strive to increase from 50 million tons to 100 million tons. Conch has formed a complete cement manufacturing industry chain and has the leading advantage of building and operating the world's most advanced cement plant from a high starting point. For going global projects, conch adheres to the principle of "internationalization must be localized", makes good use of local people and obtains the support of the host country. At the same time, pay attention to the long-term effect, combine the reality of overseas projects, apply advanced environmental protection technology and successful experience, take lean management as the main line, promote cleaner production, use new technology to reduce energy consumption, and build a green ecological factory overseas.
"Whenever we run to catch up with conch and reach the destination, we find that conch has stood at a higher position. Taking the lead in scientific and technological innovation, talent reserve and enterprise management, conch can realize higher profits than the same industry. These profits enable conch to have more funds to invest in scientific research and higher salary to attract talents. Such repetition has formed a closed-loop virtuous circle. " An industry insider who has visited conch for many times commented.
