1. 隔離設備系統,并將換熱器里面的水排放干凈。

2. 采用高壓水清洗管道內存留的淤泥、藻類等雜質后,封閉系統。

3. 在隔離閥和交換器間裝上(不小于1英寸=2.54厘米),進水和回水口都應安裝。

6. 反復循環清洗到推薦的清洗時間。隨著循環的進展和沉積物的溶解,反應時產生的氣體也會增多,應隨時通過放氣閥將多余的空氣排出。隨著空氣的排出,換熱器內的空間會增大,可加入適當的水,不要一開始就注入大量的水,可能會造成水的溢出。

7. 循環中要定時檢查清洗劑的有效性,可以使用PH 試紙測定。如果溶液保持在PH值2‐3時,那么清洗劑仍然有效。如果清洗劑的PH 值達到5‐6時,需要再添加適量福世泰克清洗劑。最終溶液的PH值在2‐3時保持30分鐘沒有明顯變化,證明達到了清洗效果。注意:福世泰克清洗劑可以回收后重復使用,排放會造成浪費。

8. 達到清洗時間后,回收清洗溶液。并用清水反復沖洗交換器,直到沖洗干凈至中性,用PH試紙測定PH值6~7。

10. 設備穩定后,記下當前的介質過流量、工作壓力、換熱效率等數據。

13. 如企業需要設備進行鈍化預膜處理,可按以下流程進行操作:將鈍化預膜劑按推薦稀釋比泵入設備中(同時在循環槽內懸掛試片);按推薦時間循環、浸泡;檢測預膜效果(紅點法或藍點法);排放;水沖洗干凈至中性(用PH試紙測定PH值6~7)。

1. Isolate the equipment system and drain the water from the heat exchanger. 2. High-pressure water is used to clean the mud, algae and other impurities in the pipeline, then the closed system is closed. 3. Install ball valve not less than 1 inch 2.54 cm between isolation valve and exchanger, both inlet and outlet shall be installed. 4. Connect a delivery pump and a conduit so that the cleaning agent is pumped in and out from the bottom of the heat exchanger. 5. The required proportion of FUSITEC cleaning agent can be adjusted according to the specific situation. 6. Repeat the cycle until the recommended cleaning time. As the cycle progresses and the sediment dissolves, the gas produced during the reaction increases, and excess air should be vented at any time through a vent valve. As the air is discharged, the space inside the heat exchanger will increase. Appropriate water can be added. Do not start with a large amount of water, which may cause water overflow. Kill. To check the effectiveness of the cleaning agent regularly during the cycle, the Ph test paper can be used. If the solution is kept at a Ph of 2 something 3, the detergent is still effective. If the PH of the cleaning agent reaches 5 something 6, you need to add an appropriate amount of FUSITEC cleaning agent. The PH value of the final solution remained unchanged for 30 minutes at 2 something 3, which proved that the cleaning effect was achieved. Note: FUSITECH cleaning agent can be recycled and reused, emissions will cause waste. 8. After the cleaning time is reached, the cleaning solution is recycled. The exchanger was rinsed repeatedly with water until it was clean and neutral. The Ph value of the exchanger was determined with Ph test paper 6 ~ 7. 9. After the completion of cleaning can start running. You can also suppress the test to see if there is a leak. If there is a leak, you can use meijiahua polymer composite materials for repair and protection, and can greatly extend the service life of equipment. 10. After the equipment is stable, record the current media flow rate, working pressure, heat transfer efficiency and other data. Kill. By comparing the change of the value before and after cleaning, we can calculate the production cost, such as electricity and coal cost, and the improved work efficiency, which is the value compensation of adopting fusitech technology. 12. The same operation method can also be used for plate type, frame type heat exchanger cleaning. 13. If the enterprise needs equipment for passivating pre-film treatment, the following procedures can be followed: The passivating pre-film agent is pumped into the equipment at the recommended dilution ratio while hanging the test piece in the circulation tank; Red Dot method or blue dot method; discharge; Rinse Clean to neutral Ph test paper to determine Ph 6 ~ 7. 14. After passivation prefilming, it is better to use ventilation equipment such as fan to dry the system, which can ensure and enhance the passivation prefilming effect.
