Description

一种中央空调水系统清洗方法
技术领域
本发明涉及一种中央空调水系统清洗方法，属于空调清洗技术领域。
背景技术
中央空调在调控温度方面起着举足轻重的作用。空调经过长时间运行，空调冷冻水、冷却水系统、制冷主机及风机散热盘管不可避免的出现了水垢、锈蚀和粉尘问题。
空调系统的冷却、冷冻水未经处理有极强的腐蚀性，如将普通钢片或铁钉放入水中，几天后就会出现铁锈，放置时间越长则锈蚀越严重。设备内壁常因腐蚀造成锈渣脱落，甚至于穿孔，脱落的锈渣会堵塞盘管，使制冷效果下降；同时腐蚀的存在使设备的使用寿命大为缩短。管道内溶于水中的无机盐结晶后，在冷凝器等换热面管壁上形成水垢，导致热交换效率降低，制冷效果下降，严重时下降30%。同时垢的增加，则用电量增加或燃料消耗量上升，严重时增加35%。此外，由于水的泥土、泥沙、腐殖物形成污垢，加上细菌、藻类等微生物及其分泌物形成的生物粘泥，严重时造成管路堵塞；而污垢、粘泥会影响热交换效率，多耗电能，造成高压运行，严重时造成超压停机。所有这些严重地影响了空调系统的正常运行。所以中央空调系统出现水垢、锈蚀、淤泥、细菌和藻类问题将直接导致制冷能力减弱，使用寿命缩短、运行可靠性降低、能耗提高导致运行费用增加。
发明内容
本发明的目的在于提供一种中央空调水系统清洗方法，以便更好地针对中央空调水系统进行清洗清洁处理，改善其使用效果。
为了实现上述目的，本发明的技术方案如下。
一种中央空调水系统清洗方法，具体步骤如下：
（1）杀菌灭藻清洗：清洗膨胀水箱，在水箱中投加杀菌灭藻剂，开泵循环8～24小时，进行全系统的杀菌灭藻和污泥清理处理；
（2）清洗系统：在冷冻水系统最低闸阀处排放冷冻水后，加至水满，然后于膨胀水箱投加系统清洗剂，开泵循环24～36小时，将系统内的浮锈、油污渗透剥落；
（3）预膜：排放冷冻水，将清洗出的锈渣、污泥排出冷冻系统之外；拆开冷冻系统的过滤网，清除滤网杂物，再封好过滤器，向系统注水排气至冷冻水满；然后在膨胀水箱投加预膜剂，开冷冻泵循环2～48小时，排放2/3水进行第四步；
（4）缓蚀阻垢：在膨胀水箱中投加缓蚀剂，开泵循环2小时，使药物均匀分布在系统中；试测PH值，PH值正常在8～10的情况下做浸片试验；
（5）用高压水枪清洗冷却塔盘，洗净其灰尘、污泥和青苔；在冷却塔盘中投加杀菌灭藻剂，开泵循环16～24小时，进行灭菌灭藻处理；在塔中投加系统清洗剂，开泵循环16～24小时，该药剂能把冷却系统的浮油污渗透剥落；排放冷却水，清洗冷却塔，拆开冷却水系统Y型过滤器，清洗过滤网内杂物，加满；在冷却塔中投加预膜液，开泵循环48小时，该药剂能在金属表面涂上一层膜，防止水中溶解氧吸附在管壁上。
进一步地，上述清洗方法中，所使用杀菌灭藻剂由以下物质混合制备而成：异噻唑啉酮5份、脂肪胺6份、甲叉二硫氰酸酯30份、N，N‐二甲基甲酰胺40份、异丙醇25份，聚丙烯酸钠12份，去氢松香胺聚氧乙烯醚9份，三氯异氰尿酸4份、过醋酸5份。
