this year,
the output value of Queshi Cement increased by 30% year on year. Once on the verge of bankruptcy, the small cement plant has now become a state-level high-tech enterprise integrating cement clinker , commercial concrete production and land and water transportation, and its Yangluo Industrial Park in the Yangtze River New Area has been recognized as a green factory by the Ministry of Industry and Information Technology.On June 28, Wei Huashan, Party Secretary and Chairman of Queshi Group, said in an interview with reporters: "Many key projects in China use Queshi cement." The most advanced cement production line
built
by Washi Group
covers more than
30% of the key projects in Wuhan. "Washi" implies the spirit of Nuwa mending the sky and the quality of five-color stone. Wei Huashan said: "The name of Queshi Group is to show the pragmatic spirit of constantly surpassing oneself, vigorous progress and down-to-earth."
Queshi Cement Laboratory
Queshi Cement was a state-owned enterprise, initially established in 1970, renamed Wuhan Yangluo Cement Plant in 1983, changed to Hubei Queshi Co., Ltd. in 1996, restructured into a private joint-stock enterprise in 2004, and established Queshi Cement Group in 2014. Before the restructuring of the
enterprise, due to the single product and the backward technology of the vertical kiln production line, it was facing bankruptcy. In 2008, the enterprise eliminated backward production capacity, invested 1.5 billion yuan to optimize and upgrade the technology and equipment, introduced the world's advanced new dry process production technology for clinker production, and used the domestic advanced roller press semi-finished grinding production technology for cement grinding to support the slag powder production line, which was popularized and applied by the industry. Xu Baoguo, director of the
grinding plant, recalled that after the green cement grinding production line was put into operation, one person could now complete what the original 10 people had done.
In order to promote the development of green and intelligent transformation, in recent years, enterprises have started the transformation of intelligent manufacturing production lines, initially realizing the networking, digitalization, intensive management of factories and intelligent control of some processes. In addition, through technological transformation and energy-saving and consumption-reducing technology, the power consumption per ton of cement grinding is less than 23 kilowatt-hours, reaching the first-class energy efficiency, saving about 10 million kilowatt-hours of electricity annually, reducing the dust emission concentration to less than 5 mg per cubic meter, achieving ultra-low emission and realizing cleaner production. Wang Guojian, Chief Quality Engineer of Queshi Cement Group, Queshi
Cement Intelligent Control Center
, introduced that the company's leading product "Queshi" brand cement factory quality rate reached 100%, which was assessed as "national authoritative testing standard product" by China Quality Inspection Association. The company's laboratory has been assessed by the National Cement Quality Inspection Center as the fixed value inspection unit of the national cement standard sample.
At present, the Group's cement and commercial concrete products cover more than 30% of key projects in Wuhan, and are sold to surrounding provinces. It has participated in key projects such as Beijing-Kowloon Expressway, Wuhan Rail Transit, Tianhe Airport Phase 3, Shuangliu Bridge, the main pier of Yanji Bridge and Hefei-Wuhan High-speed Railway. Many projects have been awarded national and provincial model and demonstration projects, forming a brand effect. On June 15, the reporter came to Yangluo Cement Park, located in the Yangtze River New Area, to
build the greenest garden-style factory
to reduce carbon emissions by 15730 tons
a year. Entering the factory area, we can see the shade of trees, tall trees standing tall and straight around the factory, green leaves shining in the sunshine, in sharp contrast to the tall cement cylinders in the factory area. There are small green gardens on both sides of the spacious road
in Queshi Cement Factory
. There is a quiet and beautiful pond in the west of the factory area, surrounded by various flowers and trees, which are reflected in the water and interesting with the fish.
It used to be "grey on sunny days and muddy on rainy days", but now it is a garden-style factory. The head of the comprehensive management department of Queshi Cement Group Co., Ltd. provided two black-and-white photos to reporters. The old cement plant in the photo is dilapidated, poorly equipped and dirty, which is quite different from today's Yangluo factory area.
In
Queshi Cement Factory, it is reported that the Group has carried out factory greening and home decoration in the park, with the greening rate of the factory reaching more than 30%, and has built a garden-style factory. The factory adopts advanced energy-saving and environmental protection equipment and technology at home and abroad, and implements fully enclosed production for dust collection and pollution point sources. The annual comprehensive utilization of industrial waste residues such as fly ash and desulfurization gypsum from power plants is 1 million tons.
High pollution and high energy consumption are the stereotypes of the traditional cement industry. "In fact, that is already history." Wang Guojian said that modern cement enterprises pay attention to green manufacturing, comprehensive utilization of solid waste and development of circular economy.
In Queshi cement production workshop, a large number of solid wastes such as industrial waste, desulfurized gypsum and fly ash are used as green materials for cement and clinker production, which not only solves the environmental pollution caused by solid waste discharge, but also reduces the consumption of natural raw materials. There is also an intelligent energy storage facility next to the
production workshop, which uses high-safety lithium iron phosphate batteries, cold energy storage equipment, energy management system and other information technology to charge at low electricity prices and discharge at high electricity prices, with an estimated annual discharge of about 2.2 million kilowatt-hours, reducing carbon emissions by 15730 tons a year.
