DBHZ2、CDBHZ2系列冷却塔安装及使用说明

一、安装时的注意事项

为了能充分发挥冷却塔的功能，应选择良好的安装场所。

（1）应放置在通风良好洁净的场所。（2）由冷却塔排出的湿热空气不会被再吸入冷却塔内的场所。（3）应避免在多灰尘，酸性气体的场合使用，否则会导致热交换器以及配管的腐蚀。（4）应避免在烟窗以及能受到热源辐射处使用。（5）冷却塔的进风口和墙壁之间的距离如下：单塔型为2米，双塔型为2.5米，三塔型为3.5米，四塔以上为5米以上，墙壁高度应低于冷却塔整体高度。墙壁过高时，因风向回返引起短路，以致影响冷却塔的性能。（6）冷却塔的排气口和障碍物之间的距离应为5米以上为宜。

二、管道配置

（1）对制冷设备和冷却塔之间的管道配置一般按管道配置图进行。同时也应参考制冷设备和其它机器的使用说明书进行。

（2）除了循环水输入口外，应按S311规范 { P { = } 9 . 8 x 1 0 ^ { 4 } P a } 进行法兰与管道的连接。

（3）循环水泵吸入部分应设置在低于冷却塔水盘水面的位置。

（4）应设置管道台架使冷却塔不承受管道的重量。

（5）布水槽有若干个时，应在各布水槽的输入口设置蝶阀。

（6）在冷却塔的附近应对供水管设置支撑台架。

三、配线

应按照设备技术标准及电力规范正确的进行电机的配线工作。

（1）应确定适用适当的热继电器，交流接触器、保险丝、开关装置及配线。（2）有关电机的配线，对于正相应进行U和V的交换。（逆相配线下，风机作正回转），必须确认从上往下看时风机回转方向应为顺时针方向。（3）应检查电机接线端子是否拧紧。即使只有1根电线松动，也会造成电机单项运转，以致烧坏电机，应十分注意。

四、运转时注意事项

（1)运转7-10天后，应重新调整皮带。在运转初期，因皮带与皮带轮之间的磨合等原因，皮带的张力会减弱。（2）冷却塔的性能与循环水量有关，应检查是否达到标准水量。（3）应充分注意噪音，振动和电流值。有异常时应参（故障原因和对策表）尽快进行处理。（4）填料的耐热温度为65摄氏度，不要流入超过耐热温度的循环水。在风机停止状态下，流入循环水时更应注意。即使是临时流入超过耐热温度的循环水，也会导致填料的弯曲变形。

五、维修管理

应定期进行冷却塔的检查工作：

（1）应定期消除布水槽和过滤网上的残留物，保证其运行畅通。（2）应进行适当的抽风，并充分进行循环水的水质管理，否则会导致冷却塔及制冷设备、管道等的故障，详细情况请参第八条“循环水水质管理”及第九条“补给水量”。（3）以每天运转8-10小时计算，每三个月应进行一次减速机轴承检查并添加油脂。（4）皮带过紧会导致轴承磨损，皮带过松会导致皮带打滑发热从而降低使用寿命。（5）V型联组皮带的正常使用寿命为1年，应备有V型联组皮带的备用品。（6）应注意是否有因风机表面粘附灰尘而引起失去平衡的情况。（7）应除去皮带轮表面的锈斑，否则会加快皮带的磨损。

（2）进行开关运运转时，应保证叶轮上不积雪。
（3）用低温水进行循环时，有可能布水槽及填料会冻结，应十分注意。

八、循环水的水质管理

任何良好的循环水中也稍微存在腐蚀物质及碳酸钙等难容物质，并且会随着时间的增长而浓缩，再加上受大气污染的影响，腐蚀性物质及难溶物质的浓度将逐渐增大，以致引起故障。一般情况下，应参考水质标准值来决定补充水的流量及是否需要投入水质处理药剂等，以进行适当的处理。

九、有关补充水量

循环水因以下（1）一（3）原因而减少，应按此减少量进行补充。

（1）蒸发损失：冷却塔将蒸发一部分的水，以使循环水冷却，循环水量因此将减少。（2）水滴损失：随湿热气体一起排出的水滴和由进风百叶窗处飘散的水量的和。（3）排污：因冷却塔经常蒸发一部分的水，以致留下的循环水中的溶剂热成分并浓缩。为使循环水在一定的水质条件下进行运转，将一部分的循环水排出于外部，以保持适当的水质，这种工作称为排污。（4）补充水量 \mathbf { \Sigma } = \mathbf { \Sigma } 蒸发量 ^ + 水滴损失 ^ + 排污量：一般可以认为补充水量为循环水量的 2 8 % 左右。

6、Precautions for long-term shutdown

(1) In winter,thepipeline willbreakdue tofreezing,sothe circulating watershouldbedischarged,and the
waterin thewatersupplypipeand its valveshould also be discharged. (2)The water in the ponding disk and water tank shallbe drained and cleaned internallyThe drain valve
shallbeopenedtodrainuntil it isexhausted. (3) Check whether the lock nutsof each part,especially the fanand motorare loose. (4)Loosenthebeltso thatitdoesnot takeunnecessarytension. (5)The exhaust port and towerbody shallbe protectedbya cover. 7、Precautions for winter operation in cold areas (1) It shallbe noted that the louver shallnotbesealed bysnoworice,otherwise the motor current will rise
andburn out. (2)When the switch isoperated,it shallbe ensured that there is no snowon the impeller. (3) Whencirculating with low-temperature water,it ispossiblethatthe waterdistribution tankandfiller will
freeze,so greatattentionshouldbe paid. 8、Waterqualitymanagementofcirculatingwater

Any good circulating wateralso has slightly corrosive substances,calciumcarbonateand other hard to containsubstances,whichwillbeconcentrated withthe increaseoftime.Inadition,due totheimpactof air polltion,the concentration of corrosive substances and hard to dissolve substances willgradually increase, resulting in failure.In general,the flowrate of make-up waterand the need for water quality treatment chemicals should be determined by reference to the standard value of water quality,soas to carry out appropriate treatment.

冷却塔系列产品 Coolingtower series products

9、Relevantsupplementarywatervolume

If thecirculating water isreduced due tothe followingreasons (1)-(3),it shallbesupplemented accordingtothereducedamount.

(1)Evaporation loss:the cooling towerwillevaporatepartof the water tocool thecirculating water,so the circulatingwatervolumewillbereduced.

(2) Water drop loss: the sum of the water drop discharged together with the hot and humid gas and the waterflowfromtheairinlet louver.

(3)Blowdown: because the cooling tower often evaporates part of the water,the solvothermal compositionof theremainingcirculating waterisconcentrated.Inordertooperate thecirculating waterunder certainwater quality conditions,a partof the circulating water is discharged from the outside to maintain properwaterquality,which iscalled blowdown.

(4) Make up water \mathbf { \Sigma } = \mathbf { \Sigma } evaporation ^ + water drop loss ^ + sewage discharge:Generally speaking,make-up water isabout 2 8 % of circulating water.

十、故障原因及对策

10、Fault causesand Countermeasures

闭式冷却塔

选型方法

闭式冷却塔选型，一般先求得设备满负荷运行产生的热量Qs（kcal/h），根据冷却塔的技术参数，然后找到相对应冷却塔的冷却能力。

在常见的环境条件下，我们可以用以下简便方法计算设备运行产生的热量Qs:

1： { Q s } = 流量（L/h）流体比热 x 温升
2: \scriptstyle { \mathsf { Q } } _ { { S } ^ { = } } 设备运行的无效功率 x 8 6 0
3： \scriptstyle { \mathsf { Q } } _ { \mathsf { S } ^ { = } } 淬火工件产量 ( { k s / h } ) x 工作的热熔
4： \scriptstyle { \mathsf { Q } } _ { { S } ^ { = } } 压缩机功率 x 1 . 2 x 8 6 0

Fortheselectionof closedcooling tower,the heatQS(kcal/h) generatedbyfulloadoperationof the equipment is generally obtained first,and then the cooling capacityof thecorresponding cooling tower is foundaccording tothe technical parametersof thecooling tower.

Under common environmental conditions,we canuse thefolowing simple methods to calculate the heat QS generatedby the operationof the equipment:

1:QS \mathbf { \Sigma } = \mathbf { \Sigma } flow ( \mathsf { L } / \mathsf { h } ) specific heatoffluid x temperaturerise 2 : { \mathsf { Q S } } = invalidpowerofequipmentoperation x ~ 8 6 0 （20号 3 : Q S = output of quenched workpiece (KS /h) x working hot melting 4: Q \mathsf { S } = compressorpower x \ 1 . 2 x 8 6 0

型号说明Model description

闭式冷却塔

工作原理

冷却流体在闭式冷却塔的盘管内流过，热量向盘管管壁传导：塔顶风机做抽风运行，外循环喷淋水与风机引入的新风在塔内充分接触，进行潜热和显热交换，使喷淋水水温降低，温度较低的喷淋水在盘管管壁外形成水膜，吸收盘管管壁的热量，从而带走介质的载热，达到冷却的目的。塔内的预冷填料片有助于外循环的进一步冷却。

在热交换过程中，盘管内的载热介质因为没有与空气直接接触而保持其原来的品质特性，不会被污染、吸湿、挥发。盘管外的喷淋水除少量的蒸发损失外，汇聚于塔底水池，循环使用。

闭式塔适用于被冷却流体不能与外界空气直接接触，且进口温度低于 8 0 ^ { \circ } { C } ，有充足的喷淋水源及水源水质不易结垢的场合。

结构特点说明

1、采用预冷散热填料和换热盘管协同排热结构，冷效好，体积小。
2、进风处设进风百叶，避免阳光直射入塔内，藻类滋生，喷淋水质清洁。
3、换热管采用T2紫铜管，设计耐压 1 . 6 { M P a } ，保持流体免于污染。
4、换热盘管采用模块式设计，设有检修门，可方便维护喷头、填料、浮球阀等内部构件。
5、采用铝合金轴流风机，出口风速高，避免热空气回流，运行噪声低。

说明

1.查表的相互顺序为湿球温度t℃-水温（△t℃）-出水温度（ { t _ { 2 } { ^ { 2 } C } } )-待修正的冷却水量QA，当水温降\triangle t = 1 0 ^ { \circ } C 或带近度 t _ { 2 } - t = 6 ^ { \circ } C 时，不要修正，即修正系数 { k } { = } 1 ，其它参数查右表确定k值，则冷却水量 { Q = K \bullet Q A } 0

2.图表中细线为一例题，设计湿球温度： { t = } 2 5 . 3 { { ^ circ C } } ， t _ { 1 } { } ^ { = } 5 3 ^ { \circ } { C } ， t _ { 2 } { = } 3 3 ^ { \circ } C ， \triangle { \sf t } = 2 0 ^ { \circ } { C } ， { t _ { 2 } - t } { = } 7 . 7 ^ { \circ } { C } 。选用 { G F N S _ { 3 } } { - } 2 0 0 0 型冷却塔 { \mathsf { Q A } } { = } 2 2 5 5 { { m } } ^ { 3 } /h， { k } { = } 0 . 8 8 0 ，则冷却水量 * \mathsf { Q } { = } 2 2 5 5 x 0 . 8 8 0 { = } 1 9 8 4 { m } ^ { 3 } / { h } . 0

3.如已知t、△t、Q求 { t } _ { 2 } ，或已知t、 { t } _ { 2 } 、Q求△t可用试算方法。
