, Qingzhou Zhonglian has found a new way of "cement +" from single cement clinker manufacturing to integrated operation of "cement + clinker + aggregate + commercial mixing" with firm belief and steady pace. Over the years, the company has adopted advanced technologies and processes encouraged by the state, strengthened the concept of energy conservation and environmental protection, adhered to the development concept of "innovation, coordination, green, open and sharing" as the starting point, and taken the road of technological innovation and development to promote transformation and upgrading. In September 2019, the company was selected as a national green factory by the Ministry of Industry and Information Technology.
Energy saving and emission reduction
is the cornerstone of green cement plant construction. The company has introduced advanced energy-saving technology and equipment to continuously reduce energy consumption and emissions in the cement production process by optimizing the production process and improving energy efficiency. Industrial solid wastes such as fly ash and desulfurized gypsum are actively used to realize the harmless treatment of raw materials. In terms of product quality control, advanced online equipment such as online neutron analyzer, online f-CaO analyzer and online laser particle size analyzer are equipped to realize real-time monitoring of the quality of each process and ensure the high quality and stability of products.
Resource recycling
company pays attention to the treatment and reuse of waste. Through the construction of a perfect waste treatment system, the waste produced in the production process will be classified, recycled and treated to maximize the use of resources. At the same time, the company actively explores alternative ways of waste utilization, such as the use of industrial wastes such as waste residue and fly ash as raw materials, and the implementation of technological innovation projects such as roller finishing grinding to improve the quality and performance of cement products. After putting into operation, the demonstration project of carbon
reduction and carbon sequestration, which helps carbon reach its
peak with an annual output of 200000 tons of carbon dioxide enrichment and purification by oxy-fuel combustion, has achieved an annual capture and purification of 200000 tons of carbon dioxide, which is widely used in many industries such as oil field flooding, carbon-rich agriculture, beer and beverage, and cold chain transportation. "Turn waste into treasure" to realize resource recycling. It can reduce the emission of 200,000 tons of captured and purified liquid CO and reduce the emission of 180,000 tons of CO paifang every year, which is equivalent to planting nearly 1.8 million trees and stopping nearly 120,000 economic cars for one year. It has become the largest and most advanced CCUS demonstration of CO de capture and purification in the global cement industry.
