因此,使用手工计算的工程设计根本没有发展的希望。

使用现代软件技术代替手工计算是不可逆转的局势,也是科学技术为我们带来的福音。

20世纪90年代,Microsoft Windows中文Windows 9X的成熟和普及又为中文界面的计算机软件提供了大发展的良机。

但是,由于开发队伍的知识老化和旧的编程思路的束缚,此项工作在工程技术界的进展异常艰难。

相当数量的工程计算软件向Windows环境的过渡仅仅是旧功能的照搬,没有充分利用Windows强大的功能优势。

还有部分软件仅仅是把手工计算模式原本不动地写成软件,因而其中充斥着手工计算时的近似、估算、简化、假说等不精确类容,大量的更加精确的数学模型没有体现在软件中。

这些软件充其量也仅仅利用了计算机优势的一半。

在换热器设计软件方面,国内的产品为数不多,功能一般。

国外同类软件价格昂贵(年租金10万元人民币以上)。

开发一个功能全面、方便实用的换热器计算软件是本系统开发者上个世纪的理想,跨越世纪的目标!终于在新世纪到来之际—公元2000年10月,THEM Ver 1.1横空出世,圆了开发者—不,是广大工艺工程师的世纪之梦。

板 式 换 热 器
使用手册
南京润维热工设备有限公司
一、概述
我公司生产的M/T/ TS型等截面与不等截面板式换热器,具有换热效率高,物料流阻小,结构紧凑,温度控制灵敏,操作弹性大,装拆方便,使用寿命长等特点,是目前国内最先进的高效节能换热设备。

该产品可处理的物料非常广泛,从普通的工业用水,到高粘度的液体,从卫生要求较高的食品液体,医药物料到具有一定腐蚀性的酸碱液体,从含小颗粒分体的液态物料到含少量纤维的悬浮液体均可采用板式换热。

二、结构原理
可拆卸板式换热器是由许多冲压有波纹槽的金属薄板按一定间隔,四周通过垫片密封,并用框架和压紧螺栓重叠压紧而成,板片和垫片的四个角孔形成了流体的分配管和汇集管,同时又合理的将冷热流体分开,使其分别在每块板片两侧的流道中流动,从而完成热交换。

其结构如下图所示:
三、换热器的工作原理
板式换热器传热机理是根据传热机理是根据热力学定律: “热量总是由高温物体自发地传向低温物体 , 两种流体存在温度差 , 就必然有热量进行传递 ”, 两种存在温度差的流体在受迫对流传热过程中 , 由于热传递板表面采用瓦楞波结构优化设计 , 其热交换率达到95%以上, 即使流体流速在雷诺准数值以下,流体在板片之间的运动亦呈三维运动 , 促使流体形成剧烈紊动 , 减少边界层热阻强化传热效率。

流程如下图所示:
板式换热器热交换原理图
四、设备操作、维护保养
1.操作前的准备
1.1首次启动换热器时,请检查夹紧尺寸a值是否处于名牌的标值之内。

1.2检查设备外形是否符合图样要求,是否在运输中产生碰伤情况。

1.3检查各接口件是否有生锈影响密封的情况。

1.4检查各紧固件是否有松动、锈斑、裂纹及螺纹磕碰现象。

2.操作注意事项
2.1使用前应对设备进行水压试验,对冷热两侧分别试压,试验压力为操作压力的1.3倍,保压时间为30分钟,各密封部位无泄漏方可投入使用。

2.2当设备用于卫生要求较高的食品工业或医药工业时,使用前应对设备进行清洗和消毒,消除设备内的油和杂物。

2.3当操作介质含有大量泥沙或其它杂物时,设备前应置有过滤装置。

2.4冷热介质时出口接管应按设备压紧板上端标记进行连接,否则,会影响设备操作性能。

2.5设备操作时,应缓慢注入低压液体,然后再注入高压液体:停车时,缓慢切断高压测流体,再切断低压测流体。

3.维护保养
3.1设备长期运行后,板片表面将产生不同程度的水垢或沉物,这样会降低传热效率并增加流阻,因此设备定期打开检查,清除污垢。

清洗板片时,不得用金属刷子,以免划伤板片,降低耐腐蚀性能。

3.2损坏的地板片应及时进行更换,若没有备用板片,在操作允许的情况下,可以拆下两张相邻板片(注:拆下的板片不应是换向板片,而应是带四孔的板片),同时相应减少压紧尺寸。

3.3维修时,对于已经老化的密封垫片应进行更换,脱落的垫片应重新更换新的卡口胶垫,如需要粘接时应清洗垫片槽,涂上粘接剂,将垫片摆正扣好。

五.设备清洗
5.1板式换热器定期检修,热效率明显降低、压降明显变化时进行清洗。

5.2清洗工作可将设备打开,逐张板片清洗,如果结垢严重,应将板片拆下,放平清刷。

5.3如果使用化学清洗剂,可在设备内部打循环,若用机械清洗,要使用软刷,禁止使用钢刷,避免划伤板片。

5.4设备冲洗后,须用干净布擦干,板片及胶垫间不允许存有异物颗粒及纤维之类杂物。

5.5清洗完毕后,应对板片、胶垫仔细检查,发现问题及时处理。

5.6在清洗过程中,对于要更换的胶垫应找准位置扣牢,并在组装前仔细检查是否完全复位。

六.故障处理
6.1设备在运行过程中常出现的故障有渗漏、泄漏、串液。

6.2产生渗漏的原因有夹紧尺寸过大,垫圈卡扣不严,垫圈表面有异物颗粒或缺陷。

应根据情况夹紧螺栓或拆装设备。

6.3若在运行过程中出现少量渗漏,应将压力降至零,拧紧螺栓,每次拧紧量2~3mm,不可过多,若拧紧后仍然渗漏则需要更换胶垫。

6.4长期运行后出现渗漏或泄漏,尺寸夹紧后仍不能解决,说明胶垫老化,应重新更换胶垫。

6.5设备出现串液现象,原因是板片裂纹或穿孔。

应打开设备,检查板片情况,个别板片出现问题应更换板片。

若使用年限过长,应更换设备。

注意:1.严禁超温,超压运行。

2.内部有压力时,不得进行任何修理或紧固工作。
