Daye Peak for Cooling Technical Transformation
Release time:
2022-07-03
1 cooling fan in waste heat power generation circulating pool and the technical transformation of 2 cement mill cement storage cooling, and has been officially put into use. Daye Peak Waste Heat Power Generation Circulating Pool has a total of
2cooling fans. Since the establishment of the plant, traditional transmission shafts and reducers have been used to drive the blades. The driving method has the disadvantages of high noise, high transmission loss, large energy loss and deformation of the link diaphragm. With the application of direct drive technology in the market, and the direct drive drive has the incomparable superiority of the traditional drive. For this reason, Daye Peak carried out transmission transformation on 2 cooling fan in 2021 , and achieved the expected results. In order to further promote energy saving and consumption reduction, Daye Peak carried out transmission transformation on the cooling fan of by using medium repair on 5 and 29 . The transformation not only reduces the overall cost of the equipment, but also improves the service life of the equipment, while also saving energy. 6
20, daye peak completed 2# cement mill cement storage cooling technical transformation, and passed the process, equipment, electrical appliances, safety and environmental protection acceptance on 23 . For a long time, the high storage temperature of cement has been a long-standing problem. Daye Peak has successively tried measures such as cooling the materials entering the mill and spraying water in the mill, but the cooling effect is not great. 2021 , Daye Peak uses advanced coolers currently on the market for cement cooling. The cooler realizes indirect heat release based on the principle of reverse flow and immersion, that is, there is no direct contact between the cooled cement and the cooling medium. While the screw conveyor is lifted from the bottom of the cooling cylinder to the discharge outlet on the top of the cooling cylinder, the surface of the cooler cylinder is cooled by a uniform and stable water curtain flowing down along the outer surface of the cylinder. In order to improve the cooling effect, Daye Peak also adds a soaking cylinder at the lower part of the cylinder, so that the lower part of the cooling cylinder is soaked in water at a lower temperature to achieve sufficient heat exchange. When the cooler is put into use, the temperature of the cement out of the mill can be reduced by about 15 ℃, and the temperature of the cement in the warehouse will be well controlled, effectively solving the problem of high temperature of the cement out of the factory in summer, and the performance and stability of the cement will be further improved.

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
