清洗Square Cooling Tower填料前需做好安全防护与前期准备，以下是完整的操作方案：
一、清洗剂选择
- 常规水垢场景：选用zhongs-206高效冷却塔填料水垢清洗剂，可深入填料缝隙分解水垢，恢复冷却效率。
- 粘泥藻类场景：选用GJ-1B杀菌粘泥剥离剂，彻底清除生物污垢，防止菌群再生。
- 安全适配场景：优先选中性有机酸类清洗剂，避免强酸碱腐蚀填料与塔体结构。
二、主流清洗方法
方法1：在线不拆卸清洗
- Close冷却塔供水回水阀门，排空塔内积水，避免清洗剂被稀释。
- 按说明书比例将清洗剂配制成清洗液，注入塔内循环30~60分钟，让清洗液充分覆盖填料。
- 用高压水枪反复冲洗填料表面，冲脱松动的污泥水垢。
- 排尽污水，用清水反复冲洗填料及塔身内外，彻底清除残留药剂。
方法2：离线拆卸浸泡清洗
- 拆除塔体百叶板，轻拿轻放逐层拆下填料，避免风化老化的填料破损。
- 用塑料布在塔旁搭建临时药池，将清洗剂与清水配制成清洗液。
- 将填料完全浸入药池浸泡2~4小时，让污垢充分溶解脱落。
- 取出填料用高压水枪逐块冲洗至表面见本色，检查无破损后回装。
- 同步疏通补水器、清理塔底盘水垢，最后整体清水冲洗后复位。
三、关键注意事项
- 清洗前必须切断冷却塔总电源，作业人员穿戴耐酸碱手套、护目镜，做好通风防护。
- 严禁过度稀释清洗剂，否则会大幅降低除垢效果，还需避免药剂长时间残留腐蚀填料。
- 若填料老化坍塌、破损率超过30%，清洗后也无法恢复性能，建议直接更换新填料。

FAQ
How to choose between a closed-circuit and an open cooling tower?
For working conditions that demand clean water (such as vacuum furnaces, high-frequency furnaces, and injection machine hydraulic oil cooling), a closed-circuit tower is preferred: the cooled medium circulates inside the coil without direct contact with air, so it resists scaling, algae and particle contamination, with stable heat transfer and low maintenance. For ordinary recirculating water scenarios with tight water budgets or cost sensitivity, an open tower costs less upfront but requires supporting water treatment.
What are the footprint and connections of a 100 t closed-circuit cooling tower?
Taking a standard 100 m3/h closed-circuit tower as an example: overall dimensions are approximately 3500 x 1500 x 2800 mm with a footprint of about 5.25 m2; inlet and outlet piping is typically DN100, with a 5-10 C temperature drop under standard conditions. Refer to the product specification table for details; non-standard dimensions can be customised on site.
How do I size the pump and head for a cooling tower?
Pump flow is selected according to the rated circulating water volume of the cooling tower; head must account for pipeline friction losses, local resistance, equipment elevation difference and the necessary margin. Pressure-bearing equipment such as injection machines also requires reserve for the working pressure. It is recommended to hand the operating data (flow, temperature difference, installation height, pipe diameter and length) to technical staff for calculation, to avoid an undersized pump or excessive head that wastes energy.
What water treatment does a closed-circuit cooling tower need?
The outer circulating water of a closed-circuit tower still contacts air, so softened make-up water, periodic corrosion and scale inhibitor dosing, and control of the concentration ratio are recommended. The inner circulating medium should be softened water, antifreeze or pure water according to process requirements; outdoor installation in winter requires freeze protection (electric tracing or draining).
