beijing bluestar cleaning company completed the high-pressure water efflux cleaning for cooling and heat exchanging equipment during the 2014 annual overhaul of changyi petrochemical. during the 18 days, 207 sets of equipment were cleaned, covering a total area of 120,000m2. this is the highest efficiency ever seen in domestic industrial cleaning.
at the end of 2012, after careful comparison and examination, beijing bluestar cleaning company imported fully automated shellside, three-nozzle tubeside, and five-nozzle tubeside high-pressure water efflux cleaning equipment from a renowned european manufacturer of cleaning equipment, becoming the first to possess this kind of equipment in china. compared with traditional equipment, it shows obvious advantages. with remote control, it allows operators to stay away from the dangerous operation area and thus ensures their safety. when cleaning tubes, the equipment covers 6 to 10 times the original number of tubes per unit time; while for shellside cleaning, the efficiency can be improved by more than 10 times. fully automated, the equipment removes human factors in the operation, ensures project quality, and prevents damage to the exchangers caused by water stains. also, the equipment effectively collects the scales cleaned off, thus ensuring sanitation at the operation site and prevents grease from staining operators.
if traditional equipment had been used in this cleaning project at changyi petrochemical, no less than eight sets of equipment and 80 highly skilled operators who work 24 hours a day would have been required to complete it within the same time frame. in comparison, only three sets of the new large-flow high-pressure efflux equipment, one five-nozzle tubeside cleaning system, one shellside cleaning system, and 20 operators were needed, and the quality was immensely higher than the traditional manual operation, especially when working on large exchangers. facing an atmospheric unit 1.5m in diameter and exchanger tubes totally clogged, beijing bluestar cleaning company used a five-nozzle tubeside high-pressure water efflux device, completed the cleaning with high efficiency and great quality, and won high recognition from the customer.
completing this project at changyi petrochemical, beijing bluestar cleaning company has fully harnessed this whole set of new imported equipment. it will devote itself to providing safe, quality, efficient, and professional cleaning services to all customers, and win more high-end customers by providing quality services.
