兰州石化公司空分车间在氧、氮生产系统的循环冷却水供求,有一套比较完善的独立自供系统。负责着车间制氧装置、1500m~3/h、3000m~3/h制氮装置的生产用循环水供应。该供水系统主要包括供水泵、玻璃钢冷却塔和储水池及供水管网,每小时的循环供水量约为550—600m~3/h。多年来,由于该系统的独立性和不易受到其它系统的污染,所以较好地保证了循环水的水质,平稳地确保了空分系统和钢厂压缩机系统的正常生产。由于空分系统基本上无污染源,所以该供水系统区別于炼油厂供水系统的一、二、三循环水场的最大特点就是没有油品污染。多年生产中,这个小系统补充新鲜水量很少,除了系统蒸发的水量损耗外基本无损耗。影响水质质量的最大因素就是通过冷却塔开口、以及凉水塔布水盘从自然界落入的灰尘和泥土,受气候影响最大的就是春季当兰州地区刮起沙尘暴
Lanzhou Petrochemical Company air separation plant oxygen and nitrogen production systems in the circulating cooling water supply and demand, there is a relatively complete system of independent self-supply. Is responsible for the workshop oxygen plant, 1500m ~ 3 / h, 3000m ~ 3 / h nitrogen plant production with recycled water supply. The water supply system mainly includes water supply pumps, fiberglass cooling towers, water storage tanks and water supply networks. The water supply capacity per hour is about 550-600m 3 / h. Over the years, due to the independence of the system and its being less susceptible to contamination by other systems, the quality of the recycled water is well ensured and the normal production of air separation systems and steel compressor systems is smoothly ensured. Because air separation system is basically non-polluting source, the biggest characteristic of this water supply system that distinguishes it from the first, second and third circulating water systems of the refinery water supply system is that there is no oil pollution. Years of production, this little system to add very little fresh water, in addition to the loss of water evaporation system basically no loss. Affect the quality of the water is the biggest factor through the cooling tower openings, as well as the cold water Taub trash fall into the dust and dirt from nature, the most affected by the climate is when the spring in Lanzhou scrape sandstorms
