Yunnan Peak Uses Staggering Peak Production to Make Technical Transformation
Release time:
2022-08-24
Following the replacement of the high-efficiency fan by the coal vertical mill ventilator in July
#, the power consumption of Yunnan peak system has decreased, but the pressure difference of the large cloth bag is still as high as3千帕, which is quite different from the 1千帕 of 2 at the beginning of the design, which not only affects the ventilation in the mill, but also affects the efficiency of the ventilator. For this reason, Yunnan peak actively communicated with the manufacturer of large bag dust collector at the beginning of 7 , and determined that the dust collector shell should be raised by 1 meters, and the filter bag and bag cage should be increased by 1 meters to increase the filter area and reduce the wind speed. at the same time, a single air chamber should blow the dust from the filter bag to separate each filter bag, drag reduction optimization scheme for improving injection efficiency. In addition, the resistance reduction transformation of large cloth bags for coal vertical mills was started in 8 September. After nearly half a month of construction, the main work was completed two days ahead of schedule and the machine test stage was entered. This technological transformation will effectively reduce the filtering wind speed and pressure difference of the large bag dust collector, and the specific impact on the output and the efficiency of the ventilator has yet to be tested in subsequent production. is affected by sulfur, alkali and other components in the original combustion material or unreasonable operation control will cause crust in the smoke chamber at the end of the kiln. Serious crust will greatly increase the labor intensity of employees, in high temperature environment exposure time will bring danger, while the growth of crust will also reduce the inner diameter of the smoke chamber shrinkage, resulting in reduced ventilation area, kiln ventilation decreased, resulting in the destruction of kiln system conditions, resulting in a greater impact on the quality of production. At present, the inner diameter of the constriction of the smoke chamber of 3200t/d
clinker production line is2.3 m. when the crust is not serious, the daily production can reach
4600t/d. when the crust is not serious, the oxygen content in the kiln is greatly reduced, and the hourly production is difficult to stabilize. During the staggered peak production of 8 months, Yunnan Jianfeng removed the traditional anti-crust castable for the shrinkage of the smoke chamber and replaced it with nano-metal ceramic microcrystalline bricks. Microcrystalline cermet materials have the advantages of excellent anti-skinning performance, excellent wear resistance, stable high temperature resistance, excellent acid and alkali corrosion resistance, and convenient installation and construction. After 3 days of construction, it will be completed on 8 15 , which will be of great help in reducing the labor intensity and operation risks of employees and stabilizing the quality of kiln system.

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
