"Washing" Healthier
News from our newspaper Yunnan Jianfeng Cement Company took advantage of the overhaul of 8 to invite professional cleaning personnel to carry out a comprehensive cleaning of coolers and waste heat power generation condensers at all oil stations in the clinker production line.
In the production process of the cement industry, due to various reasons, heat exchangers and pipeline lines will inevitably produce oil dirt, scale, deposits, corrosion products, slime, etc. These dirt will greatly reduce the heat exchange efficiency of the equipment, and the system will have a decrease in production capacity and an increase in energy consumption. When the dirt corrosion is particularly serious, the process will be interrupted, and the device system will be forced to stop, which will directly cause various economic losses, and even malignant production accidents may occur. This cleaning adopts chemical cleaning as the main method, supplemented by physical cleaning, the main process is divided into dispersion stripping, pickling, neutralization passivation and other processes.
heat exchange equipment can prolong the service life of the equipment after cleaning, maintain its normal use, and have the effect of preventing equipment corrosion; After cleaning, the equipment has better performance, reduces energy consumption and reduces its cost. Heat exchanger cleaning can reduce the probability of equipment failure, reduce production accidents and improve safety for the production process. (Chen Shiye)
