Measures to reduce the electricity consumption of compressed air in tons of clinker Wang Yongchun (Yunnan Hongta West Cement Co., Ltd. Yunnan Hongta West Anhui Cement Co., Ltd., established in 1991, is located in Dali City, Yunnan Province, is a company specialized in cement production. After more than 10 years of development, 4 cement clinker production lines have been built, and the clinker production capacity is 6000t, among which 3 production lines for clinking clinker are produced, and 1 production line for clinking clinker is 3 000t. Among them, 3 clams produce 1 000t. The clinker production line shares an air compressor station for gas supply, and there are 7 L-20 double-piston air compressors. According to statistics, since April 2009, the air compressor station of our company has a long boot time and often starts three sets. Up to 5 units can be turned on, but the compressed air pressure can not meet the production needs. Through each additional air compressor, the daily power consumption will increase by 2 880 kW.h, the number of air compressors will increase, and the power consumption will rise sharply. To this end, the company set up a research team, from the strengthening, good and implementation of the management system to tackle the air compressor electrical and mechanical consumption 1 air pressure and electrical consumption increased the reasons for the analysis and analysis (1) compressed air network branches too much, There are many gas points and large pressure loss. There are 1021 gas points for compressed air in the workshop. It does not include temporary gas points, and there are many gas equipment. The compressed air pipeline is almost all over the whole process. (2) Post personnel error The use of compressed air preheater 5 level discharge pipe and kiln tail slope sometimes cause blockage and accumulation of materials. For the convenience of the individual positions, the compressed air pipe is placed in the discharge pipe and on the slope for a long time. Low air pressure is actually the wrong way to use compressed air in the cutting pipe. It can not only avoid clogging, but also increase coal consumption and accelerate crust. In addition, the grate cooler is caused by heat radiation, poor lubrication, etc. Is successful, the design is feasible, the entire transformation project reflects the small investment, short cycle, good effect
