閉式冷卻塔在工程選型、應用中需考慮的事項
Closed cooling tower in the project selection, application of
consideration
一、使用環境
1、應避開酸性排氣、爆炸性粉塵、嚴重煤煙、超量水蒸氣場所；
2、安放在建築物旁邊，應與進風口保持足夠的距離（0.5-3m，根據型號而定）；
3、安放在井式圍牆裡，應警惕溼熱空氣迴流造成排熱故障，特殊環境可考慮引風裝置。
Ⅰ、Application Environment
1、Should avoid acid exhaust, explosive dust, soot and excess water vapor
serious places
2、Air intake should be keep enough distance (0.5 3 m, according to product
model) in next to building;
3. Installed In the well type walls, Should be vigilant the hot humid air
reflow waste heat caused by fault , please consider induced air device in the
special environment.
二、配管問題
1、配管、泵閥應安裝在冷卻塔執行水位以下，防止溢流和空氣吸入；
2、考慮裝置安放位置時，應有足夠的水泵揚程，應該考慮沿程的壓力損失和冷卻盤管的壓力損失；
3、流體冷卻的介面法蘭壓力設計為1Mpa,所有管道應考慮吊架或支撐。
Ⅱ，Tubing use
1. Tube,pump valve should be installed in the cooling tower operation under
water level, prevent overflow and air inhaled
2. Equipment placement, should have enough water pump head,should consider
the path of pressure loss and cooling coil pipe pressure loss.
3. Cooling fluid of the interface flange design pressure for 1 Mpa, all
pipeline should consider hanger frame or support.
三、噴淋系統的維護
1、隨著閉式冷卻塔的執行，水中的礦物質和其它雜質都會沉澱下來積聚在水槽裡，因此必須定期檢查水質，定期排汙清洗，這樣能較好的控制水質和防止結垢。
2、噴淋水水質要求：參照{GB50050-95頁迴圈冷卻水處理設計規範}，水質特別差的地區，應考慮水的淨化（軟化）處理。
3、噴淋水的補充量：蒸發量≤流量0.8%+漂水率≤0.1%+排汙量≤0.3%=迴圈流量的≤1.2%。
Ⅲ. Spray system maintenance
1. When closed cooling tower working, the water of minerals and other
impurities can precipitate accumulate in the sink, so must be regularly check
water quality, regularly clean sewage,This can better control water quality and
scaling prevention.
2. Spray water quality requirements: Refer to {GB50050-95 page-Cooling water
circulation processing design standard} , poor water quality special areas,
should consider water purification (softened) processing.
3. Spray water stock-recruitment: Evaporation capacity≤Rate of flow
0.8%+Drift water rate≤0.1%+Discharge capacity≤0.3%=Quantity of fluid flow
≤1.2%。
四、迴圈水
閉式冷卻塔內的迴圈水，應符合生產工藝對水質的要求，可採用軟化水或純淨水等。
Ⅳ. Circulating water
The circulating water in the closed cooling tower, should comply with the
production process on the quality of the water requirements, can use soft water
or pure water, etc.
五、閉式冷卻塔冷卻盤管的防凍（非常重要）
1、當環境溫度≤0℃時，可在噴淋水槽裡與內迴圈管路內設定加熱器，一般採用侵沒式電加熱器，同時閉式冷卻塔內的迴圈水保持最小流量。
2、裝置閒置不用時，應把管內迴圈水排除，以免低溫天氣損傷凍裂盤管。
3、最有效的方法是在閉式冷卻塔冷卻器內加註防凍液，乙二醇或丙二醇液即可，加註比例可參考下表：
防凍液適配比例表（見word文件）
Ⅴ. Closed cooling tower cooling coil anti-freeze (Very important )
1. When the ambient temperature ≤0℃, can use heater in the spray sink and
circulation within the tube, General use submerged type electric heater, at the
same time the closed cooling tower circulating water to keep the minimum
flow.
2. When equipment at break , should be let off circulating water, to prevent
cold weather damage the pipe coil.
3. The most effective way is charging antifreeze solution (Ethylene glycol or
Propylene glycol) in the closed cooling tower , Charging ratio can reference
the table below:
Antifreeze solution list （refer to WORD document）
乙二醇 0 10 20 30 40 50 60 70 80 90
凝固點 -0.0 -3.5 -8 -15 -24 -36 -48 -47 -29 -13
