1. 定位:根据预定的位置,确定循环水池的平面位置。
2. 挖掘基坑:挖掘基坑,清理基底,用碎石或砾石铺底,厚度一般为
30~50mm,并填实至高于地面50~80mm。
3. 防水处理:为了便于排水,在循环水池的内侧可以涂刷两遍沥青砂,铺两层油毡。
在池的外侧设置防水隔离层,通常用粘土夯填密实后做
成斜坡。
4. 砌筑:根据循环水池的需要,进行池壁、池底、进出水管、溢流管
等的砌筑。
5. 池内设备安装:进行池内的设备安装,如循环水泵的安装、管道的
铺设等。
6. 循环水的加入和抽出:根据需要确定加入和抽出循环水的办法。
如
果循环水较少,可以用水泵抽出,如果较多,可以在池内用管子引流
抽出。
同时注意定期观察水的流动情况,防止循环水在池内沉淀或溢出。
以上步骤完成后,循环冷却池就可以投入使用了。
注意:在建造和装修循环冷却池的过程中,应确保安全,避免对池内
设备或防水处理造成破坏,导致水源泄漏或污染。
同时,也要确保施
工质量和规范,防止出现安全隐患。
如果有任何疑问或需要进一步的
帮助,可以咨询专业的建筑或装修工程师。
冷却(冻)水不停机清洗预膜作业指导书一、冷却(冻)水系统清洗、预膜:1)冷却水系统清洗48小时清洗指标:PH值:5.00-6.00浊度:30mg/l2)冷却水系统预膜48小时预膜指标:PH值6.00-7.00浊度:20mg/l3)冷冻水系统清洗48小时清洗指标:PH值:5.00-6.00浊度:20mg/l2)冷冻水系统预膜48小时预膜指标:PH值9.00-10.00浊度:20mg/l二、冷却水系统水处理目的:1)清水清洗目的:清除系统中的杂质和污垢操作:系统充满水——开泵运行4小时——根据浊度(较高时)排水置换——测试浊度低于10 mg/l为止。
2)粘泥剥离、去油锈剂目的:剥离粘附在管壁、塔壁上的生物粘泥,以进一步净化金属表面。
操作:投药至冷却塔。
使用药剂为粘泥剥离去油锈剂。
3)化学清洗目的:清除设备内金属表面的水垢污物和油锈等杂质操作:投药至冷却塔。
使用药剂为清洗剂和消泡剂。
4)预膜处理目的:在金属表面形成一层保护膜,以起到防止腐蚀的作用操作::投药至冷却塔。
使用药剂为预膜剂冷冻水系统水处理目的:同上主要是清洗后预膜冷冻水一般将药剂投至膨胀水箱/或用泵压入系统三、通常时间安排(主要做冷却水系统,塔、泵、主机、还可单独清洗)第一天:将冷却系统清洗药剂运至现场第二天:安排人员对冷却塔填料采用化学药剂喷淋方式进行清洗;将盘内污泥进行清扫和冲刷,将悬浮物及污物清除干净。
计划:1)人员需:4+1=52)工具需:高压水枪、雨鞋、防护服、护目镜、橡胶手套、接线盘、水桶、长把刷、笤帚、簸箕、小推车、改锥一字和十字、钳子各1把、活扳手2把、350/600管钳各1把等3)材料需:塑料布或彩条布、绳子、6分塑料带线的水管1盘(50米)、6分喉箍5个麻、 14 #铁丝10米4)备料:DN15、DN20、DN32镀锌钢管短节各2个(约18公分长一头套丝)DN15、DN 20、DN32、DN40闸阀各2个第三天:系统上水——开循环泵——排水置换(4-6小时)第四天:投加去油锈剂和清洗剂。
