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.

2022 China's Top 100 Building Materials Enterprises 2022 China's Top 100 Cement Clinker Production Capacity Peak even on two authoritative lists

In March, the authoritative organization of the cement industry successively released two series of lists of China's top 500 building materials enterprises in 2022 and China's top 100 cement clinker production capacity in 2022. Jianfeng Group ranked among the "top 100" in the two lists ". The list of China's top 500 building materials enterprises was officially released in early March. This series of lists was selected by the China Building Materials Enterprise Management Association. Through more than 20 years of comprehensive data research on China's building materials industry, referring to international practices, the rankings are based on the company's annual operating income., Cement products, building ceramics, waterproof materials, aluminum-plastic profiles, coatings, glass, building materials equipment manufacturing and other sub-industries related to building materials. Jianfeng Group ranks 96th among the companies on the list and 27th among the cement manufacturers on the list. On March 16, the awarding ceremony of 2022 China's top 100 cement clinker production capacity list was held in Hangzhou. This series of lists is released by China Cement Network, an authoritative organization in China's cement industry. The ranking is based on the total production capacity (excluding the production capacity of other kiln types and grinding stations) of new dry clinker production lines completed and put into operation by Chinese cement enterprises in China as of December 31, 2022. The data statistics are calculated based on the design production capacity and 310 days of annual operation. Jianfeng Group ranked 53rd with an annual design capacity of 3.627 million tons.
