Promoting high-quality development of energy-based cities
Seek breakthrough through innovation and promote development through transformation. In recent years, relying on industrial transformation and upgrading, Yulin, Shaanxi Province, has continuously promoted the high-quality development of energy cities.
In the past, when it comes to plastic products, people are often associated with pollution. However, there is a plastic material that can be completely harmless degradation in soil, sea water and other environments. The biodegradable material, called polyglycolic acid, can be widely used in food packaging such as disposable plastic bags, and in materials such as medical surgical sutures. In September last year, the National Energy Group Yulin Chemical Co., Ltd. 50,000 tons/year polyglycolic acid degradable materials demonstration project was completed and put into operation, marking the realization of industrial production of coal-to-polyglycolic acid degradable materials.
Entering Yulin Chemical Industry, a series of products such as methanol, ethylene glycol and polyglycolic acid produced from raw coal were placed on the display platform. "Here, coal has changed from a simple fuel to a raw material for industrial production." Yang Xuechao, technical management engineer of Yulin Chemical Technology and Quality Department, said, "We have realized the complete industrial chain from coal to methanol to polyolefin and various chemical products. Black coal has thus become white 'rice'."
In recent years, Yulin Chemical industry has focused on improving the comprehensive utilization efficiency of coal as a chemical raw material, promoting the high-end, diversified and low-carbon development of coal chemical industry, and taking strengthening scientific and technological innovation as the most urgent task to accelerate the key core technology research.
In accordance with the guiding spirit of the "Fourteenth Five-Year Plan" modern energy system planning, at present, Yulin has started the construction of Shaanxi steam hydrogen fuel cell heavy truck phase I project, comprehensive construction including hydrogen production, purification, storage and transportation, hydrogen stations and other links including the industrial chain, and strive to make breakthroughs in the key technologies of the whole hydrogen energy industry chain, and promote the development and demonstration of hydrogen energy technology. In addition, Yulin is also actively developing unmanned aerial vehicle, robot and other intelligent unmanned system industry, to expand more directions for industrial transformation.
To adapt to the new trend of industrial science and technology, it is necessary to accelerate the promotion of industrial intelligence, rely on intelligence to reduce cost, increase efficiency and improve quality.
Wearing work clothes, head wearing miner's lamp, deep underground 330 meters, in Shaanxi Shaanxi coal Caojiatan Mining Co., LTD. 10 meters large mining height intelligent fully mechanized mining face, amazing is not only created here a mining height of 10 meters and many other "world first", the intelligent construction of coal mine is also impressive.
From the ground to the ground, from artificial to robot. In recent years, Shaanxi Coal Group has accelerated the construction of data standardization governance and intelligent private network. Now, even if you are in the field, you can open your mobile phone to see the specific location of workers underground; Massive coal mining equipment can operate on its own with the help of a handle... At present, Caojiatan Mining Co., Ltd. has realized the intelligent operation of the whole process of mine mining, transportation safety and production management.
"The most obvious result of intelligent production and operation of coal mine is that the number of staff required is reduced, and the labor intensity is also reduced a lot." Wang Rui, chief engineer of Caojiatan Mining Co., LTD., said that the reduction of workers and burdens at the mining face brings efficiency and safety. At present, only five to seven people are needed for one working face, but the maximum daily production capacity can reach 62,000 tons of coal. In terms of safety production, the ventilation system of the coal mine realizes intelligent generation of ventilation control schemes through real-time calculation of ventilation parameters, intelligent remote monitoring of equipment and other technologies. Intelligent systems such as gas disaster prevention and control system and intelligent and accurate fire monitoring and early warning also greatly reduce production risks.
