1、敞开式循环冷却水系统产生的问题:腐蚀、结垢、微生物生长。2、敞开式循环冷却水处理的重要性:减少腐蚀、防止结垢、控制微生物及生物粘泥形成。如前所述,循环水长期循环使用后,必然会带来沉积物附着、金属腐蚀和微生物滋生这三个问题,而循环水处理就是通过水质处理的办法解决这些问题。这样做法的好处如下:(1)保持设备的正常运转:没有沉积物附着、腐蚀穿孔和粘泥堵塞等危害,循环水系统中的换热器就可以始终在良好的环境中工作。除计划中的检修外,意外的检修事故就会减少,从而在循环水方面为设备的正常运转提供了最有效的运行保证。(2)节约水资源:如果某企业采用直流冷却水系统,则每小时耗水量达23500m3;若改为循环冷却水系统后以1.5倍的浓缩倍数运行,每小时耗水量降为1100m3,如果将浓缩倍数提高到3倍,则每小时耗水量只需550m3。节水效果明显。(3)节省电力、降低能耗:资料介绍,当机组蒸发压力一定时,冷凝温度每增加1℃,压缩机单位制冷理的耗功率将增加3~4%。据中央空调机组运行数据表明,凡未进行水处理的空调机组运行电耗将增加10~30%。若机组容量300RT,设备效率0.78KW/RT,平均负荷80%,一年运行5000小时,则一年多浪费电力为:300×80%×0.78×5000×(10-30%)=9.36-28.08万度。若每度电1.20元,则浪费电费11....

  • 1.Central air conditioning yellow water how to do?
    A:
    Central air-conditioning chilled water and condensate water are recycled water, the cycle will be adsorbed in the air of dust, foreign bodies, etc., water will generate microorganisms, so require regular replacement of water, if dirty very interested, or even to add special cleaning agent Cleaning; if condensation in the condenser more scale, will result in cooling effect of central air conditioning decreased, electricity consumption increased, so also regularly open the cleaning condenser. The way to do this is to change the frequency of cooling water and condensate and to clean the condenser……
  • 2.Circulating cooling water algae growth in a lot of how to deal with?
    A:
    Circulating water due to nutrient concentration, temperature and summer prolonged sunshine, bacteria and algae to create a rapid breeding conditions. Much like the mucilage secreted by bacteria, it allows dust and chemical buoys floating in the water to bond together to form slimy sediments. A biofouling sludge attaches to the heat transfer surfaces of the host condenser Heat transfer filler), in addition to causing corrosion under the scale, but also to reduce the flow of circulating water, reducing heat exchange efficiency, increase power consumption and host load, in severe cases will plug the pipeline……
  • 3.Cooler fouling can clean it?
    A:
    Can be cleaned. Cooler fouling is generally divided into two types of tube fouling and tube fouling, as circulating water generally use soft water, so fouling tube generally does not appear, unless your circulating water is not soft water, remove the detergent first Use soft water cycle. Most of the cooler scaling is outside the tube scaling, there are two reasons for its study, first, the circulating water pipe is too high, because the spray water is generally used groundwater that is hard water, so if the tube temperature is too high will make the spray water temperature Rise, the formation of scale in the pipe wall, the second is spray water itself with high Mg and other elements, especially in mountainous areas, the water is relatively hard……
