冷却塔小型报价
1)冷却塔应冷效高、能耗省、噪声低、重量轻、体积小、寿命长、安装维修简单、飘水少。
2)选用的成品冷却塔应符合《玻璃纤维增强塑料冷却塔第2部分:大型玻璃纤维增强塑料冷却塔》 GB 7190.2-1997中要求。
3)如设计工况与低温型冷却塔的标准工况的规定差距较大时,应根据产品样本中提供的热力性能曲线选定。
4)制造厂家所提供的热力性能曲线,如采用模拟塔上的试验数据整理绘制,则应根据模拟塔的试验条件与设计塔的运行条件的差异,对模拟塔的试验数据进行修正,修正系数0.80~1.00。
5)冷却塔的位置,应与建筑物保持一定间距,并避免布置在热源、废气和烟气排放口附近,如不能满足上述要求时,应采取技术措施,同时对热力性能进行校核。
6) 循环冷却水中应不含油类及对玻璃钢溶蚀的物质,水的浊度不应大于50mg/L。并应采取灭藻及水质稳定措施。
7) 设计循环水量不宜超过成品冷却塔的额定水量,如循环水量达不到额定水量的80% 时,应对选定的冷却塔配水系统进行校核。
8)冷却塔的数量宜与空调制冷机组数量相匹配。
9)根据对民用建筑噪声控制要求,可通过噪声的空间 衰减计算,选定低噪声或超低噪声冷却塔,如仍不能满足环境噪声指标时,应采取降噪措施。
10)宜在冷却塔附近加设屋顶消火栓和冲洗设施,作为灭火和冲洗淋水填料和塔体内沉积物之用。
横流式冷却塔的剖面如图所示。环境空气在轴流风机B 产生的负压作用下从进风口横向流经冷却塔填料E,与纵向流过的冷却水进行换热后,从出风口流出,在此过程中,空气与冷却水进行显热和潜热交换,空气温度升高,相对湿度增大;冷却水从进水管 A 进入冷却塔,经过布水系统D均匀分布,在重力作用纵向流经冷却塔填料 E,与横向流过的环境空气进行换热后汇集至塔底的集水池 G,并通过冷却水出水管 F 流出,在此过程中,冷却水与空气接触传热和相变传热,冷却水温度下降,部分冷却水蒸发,达到冷却目的。
11)冷却塔材质应选用阻燃型,并符合防火要求,应在主要设备表和订货合同中标明。
12)选用成品冷却塔时,应注意电气控制的配合和协调。
优点
1、冷却介质全封闭循环,可防止杂物进入冷却管路系统和冷却介质的蒸发损耗。
2、使用软水作为冷却介质,不结垢,不堵塞管路,故障少。
3、采用风冷和喷淋水蒸发吸热双重冷却方式,冷却效率高。
4、该装置体积小,占用空间小,移动及放置方便,无需修建水池。
5、采用自动化智能控制,可根据工况要求自动变换冷却模式,操作简单可靠。
6、用途广,可直接冷却淬火液、油类、醇类等对换热器无腐蚀作用的介质,介质无损耗,成份稳定。

运行维护
由于多种原因,凉水塔的工业循环水未经水质处理就直接经冷却塔冷却,从而,凉水塔内填料运行一段时间后就产生粘泥,容易结疤,滋生菌藻等,致使填料淤塞、塌陷。造成塔内布水不均匀,通风不畅。形成有水区,无水区和疏水区,导致有风无水,有水无风的局面。导致凉水塔的冷却效果降低。因此,在进行冷却时应先对水质进行处理,防止因水质过脏导致冷却效果下降
