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.

Daye Peak Declared 4 Invention Patents Last Year
In 2019, Daye Jianfeng Cement Company changed its thinking, actively explored and tested the use of new materials, and summarized the research results in a timely manner, and successively declared 4 invention patents. In the production process of low-alkali cement, Daye Peak changed the traditional scheme of using high-grade sandstone ingredients alone to replace part of the sandstone and part of the iron correction material with iron ore waste soil, which not only controlled the alkali content in the clinker, but also increased the Al2O3 content in the clinker, ensuring the easy burnability and high early strength of the clinker. Innovation has also been made in the raw material batching scheme, breaking the original high-grade and low-grade sandstones used together and changing them to separate batching of high-grade and low-grade sandstones respectively, thus avoiding the disadvantage of easy material segregation in the process of high-grade and low-grade sandstones used together. At the same time, the original four-component batching is changed to five-component batching, so that low-alkali clinker can be freely switched, which is convenient for production organization and production cost. On the basis of a series of innovative achievements, Daye Peak declared four invention patents in 2019: "a technology for producing clinker from gas sludge and dust collection in steel mills", "a method for treating sludge in machine-made sand mills", "an improvement in raw material batching method" and "a technology for producing low cement from iron ore mining waste soil", all of which have high practical value.
