Daye Peak Desulfurization Project Breaking Earth
News # July 22 , accompanied by a series of firecrackers and a wave of the excavator's vibrating arm, Daye Peak Cement Company's desulfurization project officially broke ground. This is another environmental protection project implemented by the company after the denitration project.
In the "Emission Standard for Air Pollutants from Cement Industry" implemented on 3 1 , 2014 , the emission of sulfur dioxide (SO2 ) per standard cubic meter in cement production is required to be no higher than 200 mg, while the standard in economically developed regions such as Guangdong, Shandong, Beijing, Tianjin, Hebei and Hangzhou is no higher than 100 mg, some provinces that implement total emission control will control the emission requirements below 20 mg. The continuous stringent emission standards have brought great environmental pressure to the cement industry. Sulfide in cement production mainly comes from sulfur-containing raw materials such as coal, limestone and clay. At present, the mainstream desulfurization methods include wet desulfurization, dry desulfurization technology, ammonia desulfurization technology and compound desulfurization technology. The desulfurization project implemented by Daye Peak this time adopts limestone wet flue gas desulfurization process, which is currently the most widely used and mature standard desulfurization process technology in the world. The process uses cheap and easy-to-get limestone as a desulfurization absorbent, limestone is crushed and ground into powder and water mixed into an absorption slurry, in the absorption tower contact with the flue gas mixed, the sulfur dioxide in the flue gas and the calcium carbonate in the absorption slurry, the air drum into the chemical reaction is removed, the final reaction product is gypsum. The flue gas after desulfurization is removed by the mist eliminator and discharged into the chimney after warming up. The desulfurization gypsum slurry is dehydrated by the dewatering unit and recycled for cement grinding. The completion and operation of this project can not only effectively reduce the content of sulfur dioxide in flue gas, but also realize the partial self-sufficiency of desulfurization gypsum in cement grinding.

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.
