On the shore of Shengxi Lake, the water and sky are colorful.
Stepping into the factory area of Xiaoyi Dongyi Coal, Electricity and Aluminum Group Company, the lush trees and lawns on both sides of the road come into view, and when you look around, the blue factory buildings, yellow traffic markings, green plants, and red flowers look colorful against the background of blue sky and white clouds.
"For coking companies, a clean factory environment means a clear effect of low emissions and low pollution." The company's chairman Mu Jinhun wrote the slogan "Environmental protection is a conscience project" in many key locations in the factory.
Coincidentally. Next to the closed coal greenhouse of Xiaoyi Jinda Coal Coke Company, there is a vegetable garden with tomatoes, Chinese cabbage and so on. "All the dishes here are served in the staff canteen, and everyone can eat with peace of mind and happiness." It's also called self-sufficiency! Yao Shoucai, head of the coal preparation workshop, said.
"The coal storage greenhouse is 385 meters long, 89 meters wide and 38 meters high, and through fully enclosed transmission, it achieves zero pollution, which not only saves costs, but also reflects green development." Yao Shoucai introduced.
"The coking industry must develop green." Liang Hong, director of the Xiaoyi Municipal Bureau of Industry and Information Technology, said with emotion that in recent years, the Xiaoyi coking industry has been "big and small", and the 10 million-ton coal chemical circular economy park has integrated the city's coking capacity and promoted the green and low-carbon cycle development of the park. At the same time, we will extend the industrial chain, comprehensively improve quality and efficiency, and realize the transformation of enterprises to innovative, high-end intensive and green environmental protection.
Disposable cutlery, gloves, tablecloths, slippers, food bags... In the exhibition cabinet of the office building of Xiaoyi Jinhui Zhaolong High-tech Co., Ltd., a series of plastic products witness the green technology transformation of the Xiaoyi coking industry.
"These products can be completely naturally degraded, non-toxic and odorless, and are safe and harmless to the human body." Li Yajuan, the head of the company, introduced. Jinhui Zhaolong is a wholly-owned subsidiary of Jinhui Energy Group Co., Ltd., which belongs to the transformation project that seeks transformation, conforms to the trend of the times and develops a green economy. "We produce new environmentally friendly plastic raw materials that account for 15% of global production capacity and 33% of domestic production capacity. The finished product has obtained the authoritative certification of the industry at home and abroad, and is exported to more than 30 countries and regions. ”
The transformation of resource-based enterprises is committed to making "old trees blossom and new flowers" while "starting a new stove". The coking industry consumes high energy and promotes waste heat power generation; coke oven gas pollutes the air, extends the industrial chain, and turns it into liquefied natural gas, methanol, synthetic ammonia, etc.; wet quenching coke consumes aquatic pollution, and starts dry quenching coke technology...
The development of the coking industry has gone through the stages of artificialization, mechanization and electrification, and is now developing in the direction of automation and intelligence. "The progress of transformation and technological upgrading is constantly reshaping the coking industry." Mu Jinhun thinks.
In the real-time picture of the headquarters of Changxin Coal Mine, in the central substation 200 meters underground 115 kilometers away, explosion-proof track inspection robots are using 5G technology for video and data transmission.
"Intelligent robot underground operation is a highlight of the smart mine, and we want to build the country's first unmanned smart mine." Zheng Peng, the investor of Changxin Coal Mine and chairman of the board of directors of Xiaoyi Pengfei Group, is full of confidence.
From 2020 onwards, Pengfei Group will comprehensively carry out the construction of 5G smart coal chemical industry and establish the "5G + Smart Coal Chemical Joint Laboratory". The overall reduction of project operation is more than 50%, the operating cost is reduced by 12%, the production cost is reduced by more than 20%, the production efficiency is increased by 40%, and the energy conversion rate is increased by more than 44%; remote control and on-site unmanned production are realized.
Liu Mingliang, deputy general manager of Xiaoyi Jinda Coal Chemical Technology Co., Ltd., is satisfied with the intelligent development of the fully enclosed arch refined coal greenhouse. He told reporters that the greenhouse coal storage is large, the use of PLC automatic coal blending control system in the transportation process, through the automatic scraper reclaimer, to achieve unmanned operation on site, to solve the problem of coal transportation continuity, large-scale operation, effectively improve the accuracy and uniformity of coal blending, coal saving results are remarkable, reduce atmospheric dust pollution.
According to the company's operational data analysis, the greenhouse can save 10,000 to 20,000 tons of coal per year, and the automation of the coal preparation system plays an important role in the staggered peak procurement of refined coal. In the winter of 2020 alone, the company purchased more than 200,000 tons of refined coal in advance when coal prices were low, and the cost was reduced by more than 20 million yuan.
Nowadays, Xiaoyi coking industry has taken the lead in entering the era of large-scale modern coke ovens in the province, continuously promoting the transformation and upgrading of equipment and green cycle development in the coking industry, and making every effort to build a modern coking industry base with the strongest, best environment, best industry and green development in the country.
