2021-12-13
News from our newspaper In the context of "Carbon Peak, Carbon Neutral " , in order to fully fulfill corporate social responsibility and promote the green development of the cement industry. In view of the current situation that the emission of CO2 in the production process is difficult to be utilized, the bulk waste residue is difficult to be eliminated, and the added value of traditional utilization methods is low, Daye Jianfeng Cement Company actively carries out school-enterprise cooperation and cooperates with Southeast University to explore new carbon capture, storage and utilization technologies to promote the resource utilization of CO2 and industrial waste residue.
This project is jointly carried out by Daye Peak and Professor Qian Chunxiang's team from Southeast University. The aim is to fix CO2 in kiln tail flue gas by using microorganisms to cooperate with industrial waste residue, and to prepare high-quality new auxiliary cementitious materials in batches to realize efficient utilization of CO2 at normal temperature and pressure. As the first demonstration application project in China to prepare carbon-fixing auxiliary gelding materials using cement kiln tail flue gas CO2 , the research and development results can provide a new way for carbon capture and utilization in the cement industry, which is original. In order to ensure the smooth progress of the experimental project, daye peak and Southeast University team have completed the whole process design, equipment construction and installation of cement kiln tail flue gas capture, maintenance and monitoring. 10 January 28 , with the first batch of steel slag powder into the experimental device, marking the official start of the experimental project. It is reported that the experimental project to complete four batches of microbial carbon fixation experiments, the follow-up will also carry out auxiliary cementitious material product preparation, concrete application experiments and other projects.
At present, the experimental project is progressing smoothly and the carbon fixation effect is obvious. The activity index of auxiliary cementitious material 28 prepared by this technology is greater than 85% , and its performance is better than the first-class technical index of GB/T 20491 "Steel Slag Powder for Cement and Concrete. Project related technology patent applications and research papers will be completed step by step.

The company requires to do a good job in summer safety production
The high temperature season is approaching, and the group company issued a notice a few days ago to make arrangements for safe production in summer. The notice requires all subordinate units of the company to attach great importance to the work of production safety in summer, and all production and business units should hold a special meeting on production safety in summer. According to the characteristics of production in summer, they should focus on safety risk analysis for mines, outdoor operations and high-temperature posts, and implement control measures to avoid the occurrence of safety accidents such as scalding, heatstroke and electric shock. In order to further strengthen the safety production management in the high temperature season, the notice requires the main person in charge of each production and business unit to lead a team to conduct a comprehensive inspection of the production and business premises according to the characteristics of summer production; strengthen the daily safety production inspection of key posts and special posts; timely rectify the found unsafe behaviors and hidden dangers; Strengthen the management of the storage and use of flammable, explosive, dangerous chemicals and drugs; cooling measures shall be taken for the space exceeding the storage temperature limit of articles. If it is found that the electrical equipment circuit and exhaust fan circuit are aged and damaged, replace them in time and keep the grounding wire in good condition. Do a good job in checking the fire pool, pipeline water pressure and fire extinguishing equipment to ensure that the fire fighting facilities are sensitive, intact and reliable. The high temperature in summer is also a period of frequent occurrence of heatstroke and other diseases. The notice requires all units to do a good job in heatstroke prevention and cooling, implement various relevant measures, and equip necessary cooling facilities or materials such as fans, air conditioners, ice cubes and other cooling facilities or materials according to the conditions of the production site; do a good job in the distribution of heatstroke prevention drugs, supplies and cool drinks in workshops, warehouses, construction sites and other production lines; strengthen canteen management to prevent food poisoning.
