Daye Peak Magnetic Levitation Centrifugal Blower Renovation
On October 28, Daye Peak Cement Company completed the upgrading and renovation of 2# Roots Blower for coal mill. The magnetic levitation centrifugal blower was successfully used to replace Roots Blower. After a week of operation, the energy saving and consumption reduction effect was remarkable.
magnetic levitation centrifugal blower is a mechatronics product, which is mainly composed of three parts: magnetic levitation bearing, permanent magnet synchronous motor and fan. It adopts the direct drive structure of high-speed permanent magnet synchronous motor, which integrates the centrifugal impeller and the motor drive. The integrated design drives the rotor to rotate at a high speed through the variable frequency power supply to generate alternating current with controllable frequency to drive the centrifugal impeller to rotate at a high speed, under the guidance and pressurization of the volute, the air becomes a gas with a certain flow rate and pressure, which is blown out from the air outlet to realize the blowing of the fan. It is put into use in the case of the same outlet pressure to make the motor running current from 291A to 261A, motor power from 157kW to 137kW, the basic realization of no vibration, no noise operation, both energy saving and environmental protection.
At the same time, in order to ensure the safe operation of the magnetic levitation centrifugal blower, on November 2, Daye Jianfeng specially invited technicians from Nanjing Magnetic Valley Technology Co., Ltd. to conduct magnetic levitation fan training. The technical personnel introduced in detail the structure of the fan, the working principle of the fan and the key technology of the magnetic bearing and the high-speed and high-power permanent magnet synchronous motor. The magnetic bearing has no contact, no lubricating oil, and ultra-low power consumption; the permanent magnet synchronous motor is small in size, light in weight and high in speed. During the training, the employees also interacted with the technicians on the daily maintenance and maintenance of the fan and the matters needing attention. (Shi Zhangliang, Liu Chao, Wang Xuejun)

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
