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 as

3千帕, 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 is

2.3 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.
