Daye Jianfeng Cement Co., Ltd. Kiln End Flue Gas Desulfurization Project
Completion Environmental Protection Acceptance Publicity
According to the requirements of Interim Measures for Environmental Protection Acceptance of Construction Project Completion (National Environmental Planning and Environmental Assessment [2017] No. 4 ) of the Ministry of Environmental Protection,
The environmental protection acceptance information of "Kiln End Flue Gas Desulfurization Project" of daye Jianfeng Cement Co., Ltd. is now publicized. Basic Information of
1. Project
Project Name: Kiln End Flue Gas Desulfurization Project
Project Construction Unit: Daye Jianfeng Cement Co., Ltd.
Project Construction Location: Yongguang Village, Baoan Town, daye city, nature of
Project in the existing factory area of daye Jianfeng Cement Co., Ltd: the construction content of the technical renovation
project is as follows:
This technical renovation project is mainly to build a wet desulfurization system for the kiln tail flue gas of the company's existing daily production 4000t cement clinker production line, adopting limestone - gypsum wet flue gas desulfurization process. The project covers a total area of 500m 2 , with a new construction area of about 450 m 2 . It mainly builds desulfurization complex building, flue gas system, SO 2 absorption system, limestone powder conveying and limestone slurry preparation system, process water system, gypsum dehydration system and supporting pipelines, etc. Power supply, water supply, compressed air and other public works rely on the existing plant.
Project Total Investment and Environmental Protection Investment: The total investment of the project is 1037 Yuan , all of which are environmental protection investment. The
project was commissioned by Huangshi Changjiang Environmental Engineering Design Institute to conduct an environmental impact assessment on 2017 9 . On 2017 11 16 , daye city Environmental Protection Bureau approved the document No.78 [2017]354 .
Implementation of 2. Environmental Protection Measures
The scope of this acceptance is Kiln End Flue Gas Desulfurization System and Supporting Facilities .
(1) Exhaust Gas Pollution Prevention Measures
Project Organized Exhaust Gas Emission Main Pollutants are SO 2 ; The main pollutant of unorganized exhaust gas emission is dust. In the
slurry preparation system, the processes of transportation, feeding, ash separation and silo are fully enclosed, and the pulping process is equipped with ash and dehumidification devices. The SO 2 in the waste gas of the rotary kiln is treated by limestone - gypsum method and discharged from the 110m high chimney at high altitude; the emission concentration of SO 2 and unorganized dust can meet the emission limit requirements of (GB4915-2013 ) "Comprehensive Emission Standard for Air Pollutants in Cement Industry.
(2) Water Environment Pollution Prevention and Control Measures
Project Drainage is divided into rain and sewage, and rainwater ditches (cement hardening) are set up. Rainwater at the project site enters the existing rainwater system in the plant area. Drainage ditches and water collecting tanks are built, equipped with cyclone machines and filtrate collection tanks. The wastewater is collected by the water collecting tanks and recycled for production without external discharge; A 570m 3 accident slurry tank has been built. The slurry discharged from the absorption tower during the accident will be collected in the accident slurry tank and recycled to the absorption tower without being discharged outside, thus having little impact on the outside world.
(3) noise prevention measures
project noise mainly comes from production equipment such as fans and water pumps, equipment is low noise equipment; The fans and pumps are all placed in closed compartments, and measures such as vibration reduction, noise elimination and distance attenuation are taken.
(4) Solid Waste Pollution Prevention Measures
The solid wastes discharged during the operation period of the project are mainly domestic garbage and desulfurization gypsum. A standardized temporary storage room for solid waste is built on the first floor of the desulfurization station. The dehydrated gypsum is collected by the temporary storage room and regularly transported to the gypsum storage yard in the plant area. As raw material, it enters the cement mill and is not discharged. Domestic waste is uniformly removed and transported by the local environmental protection department for centralized treatment.
3. Acceptance Survey Results
(I) Construction Period
During the construction period, various environmental protection measures were implemented with little impact on the surrounding environment.
(II) operation period
1 , acceptance monitoring condition
acceptance monitoring period (2019 3 July 21-22 ; 2019 172 5 March 27-28 ), the project is operating normally, design and production of cement 4000t/d ; The actual 3 September 21-22 day, 5 March 27-28 day production load all reached above 82% of , the completion acceptance monitoring condition was greater than 75% of , and the monitoring data were valid.
and Waste Gas
3 monitoring points were set up at the factory boundary to monitor the unorganized particulate matter emitted by the project for two days. The maximum concentration of unorganized particulate matter emitted from the factory boundary is lower than 0.5 mg/m 3 , does not exceed the unorganized emission limit of in table of "cement industry comprehensive emission standard for air pollutants " (GB 4915-2013 ).
During this acceptance monitoring period, SO 219 in the inlet and outlet exhaust gas of the desulfurization tower at the end of the rotary kiln was monitored. The monitoring results show that the average desulfurization efficiency of the desulfurization tower at the end of the rotary kiln reaches above 91% in the desulfurization 223. in the exhaust gas at the outlet of the exhaust pipe

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.
