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.

Publicity of Environmental Protection Acceptance for Completion of Kiln End Flue Gas Desulfurization Project of daye peak cement co., ltd. According to the requirements of the Interim Measures for Environmental Protection Acceptance for Completion of Construction Projects (No.4 [2017] of the State Environmental Regulations) issued by the Ministry of Environmental Protection, the environmental protection acceptance information of "Kiln End Flue Gas Desulfurization Project" of daye peak cement co., ltd. is now publicized. Basic Information of 1. Project Project Name: Kiln End Flue Gas Desulfurization Project Construction Unit: daye Jianfeng Cement Co., Ltd. Project Construction Location: Yongguang Village, Baoan Town, daye city, nature of the project in the existing plant area of daye Jianfeng Cement Co., Ltd.: The construction content of the technological transformation project is: This technological transformation project is mainly to build a wet desulfurization system for kiln end gas of the company's existing 4000t cement clinker production line, adopting limestone-gypsum wet flue gas desulfurization process. The project covers a total area of 500 m2, with a new construction area of about 450 m2. It mainly builds desulfurization complex building, flue gas system, SO2 absorption system, limestone powder conveying and limestone slurry preparation system, process water system, gypsum dehydration system and supporting pipelines. Power supply, water supply, compressed air and other public works rely on the existing plant. Total investment and environmental protection investment: the total investment of the project is 10.37 million yuan, all of which are environmental protection investment. The project was entrusted to Huangshi Yangtze River Environmental Engineering Design and Research Institute to carry out environmental impact assessment in September 2017. On November 16, 2017, Daye Municipal Environmental Protection Bureau issued a reply with YEHAN [2017] No. 354. Implementation of 2. environmental protection measures The scope of this acceptance is the flue gas desulfurization system and supporting facilities at the end of the kiln. (1) Exhaust gas pollution
