螺旋板换热器定期清(qing)洗(xi)的作用有(you)哪些?

　　目前，作为(wei)热(re)交换(huan)(huan)的(de)核心设(she)备(bei)，换(huan)(huan)热(re)器(qi)分为(wei)管(guan)壳换(huan)(huan)热(re)器(qi)、板(ban)式换(huan)(huan)热(re)器(qi)、螺(luo)旋板(ban)换(huan)(huan)热(re)器(qi)的(de)常见三种。以(yi)管(guan)壳式换(huan)(huan)热(re)为(wei)主(zhu)，在化(hua)工(gong)生(sheng)产(chan)中(zhong)，换(huan)(huan)热(re)器(qi)水侧结垢(gou)(gou)堵塞(sai)(sai)，氧化(hua)腐(fu)(fu)蚀(shi)穿孔，工(gong)艺侧结垢(gou)(gou)堵塞(sai)(sai)等问题严重(zhong)影响化(hua)工(gong)装(zhuang)置的(de)生(sheng)产(chan)。螺(luo)旋板(ban)换(huan)(huan)热(re)器(qi)结垢(gou)(gou)的(de)腐(fu)(fu)蚀(shi)的(de)主(zhu)要以(yi)加强冷却(que)水处(chu)理的(de)质量(liang)管(guan)理，第二定期对换(huan)(huan)热(re)器(qi)进行(xing)化(hua)学清洗钝化(hua)保护处(chu)理。钝化(hua)后换(huan)(huan)热(re)器(qi)管(guan)束表面(mian)不(bu)会发生(sheng)氧化(hua)腐(fu)(fu)蚀(shi)从而(er)避免产(chan)生(sheng)严重(zhong)的(de)垢(gou)(gou)下腐(fu)(fu)蚀(shi)发生(sheng)。从而(er)保护换(huan)(huan)热(re)器(qi)和(he)延(yan)长设(she)备(bei)的(de)使用寿命。

　　大型(xing)化(hua)工装(zhuang)置定(ding)期每年检修清(qing)洗钝化(hua)工程经验(yan)，认为换(huan)热(re)器的定(ding)期清(qing)洗有以下作(zuo)用(yong)：第(di)一：提(ti)高换(huan)热(re)效(xiao)(xiao)率，节(jie)约能源(yuan);第(di)二：延长设备使用(yong)寿命第(di)三：提(ti)高生产(chan)效(xiao)(xiao)率和产(chan)品质量 第(di)四：减少经济损失..=

　　换热器一般(ban)结垢原因是(shi)换热器设(she)备等(deng)和(he)管道(dao)线路(lu)线中都会(hui)(hui)产(chan)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)很多(duo)如结焦、油(you)(you)污垢、水垢、沉(chen)积物、腐蚀(shi)产(chan)物、聚(ju)合(he)物、菌类(lei)、藻类(lei)、粘泥等(deng)污垢。产(chan)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的这些污垢会(hui)(hui)使(shi)换热器堵塞腐蚀(shi)和(he)管道(dao)线路(lu)失效，造成化(hua)(hua)(hua)工(gong)(gong)(gong)装置(zhi)系统会(hui)(hui)发生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)产(chan)下降，能(neng)(neng)耗、物耗增(zeng)加等(deng)不(bu)(bu)良情况(kuang)，污垢腐蚀(shi)特别(bie)严(yan)重时还会(hui)(hui)使(shi)流程中断，化(hua)(hua)(hua)工(gong)(gong)(gong)装置(zhi)系统被迫停产(chan)，直接造成各种造成经济损失，甚至还有可能(neng)(neng)发生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)恶性(xing)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)产(chan)事(shi)故(gu)。化(hua)(hua)(hua)工(gong)(gong)(gong)装置(zhi)换热器等(deng)设(she)备的清(qing)洗(xi)便成为工(gong)(gong)(gong)业生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)产(chan)，尤其是(shi)煤化(hua)(hua)(hua)工(gong)(gong)(gong)、石油(you)(you)化(hua)(hua)(hua)工(gong)(gong)(gong)及(ji)热电工(gong)(gong)(gong)厂生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)产(chan)中所(suo)不(bu)(bu)可缺少(shao)的一个重要环节。目前清(qing)洗(xi)换热器主要采(cai)用化(hua)(hua)(hua)学(xue)清(qing)洗(xi)和(he)高压水射流清(qing)洗(xi)两种方(fang)法。一般(ban)化(hua)(hua)(hua)工(gong)(gong)(gong)企业认为设(she)备清(qing)洗(xi)只有在(zai)严(yan)重影(ying)响生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)产(chan)的情况(kuang)下才会(hui)(hui)考虑，其不(bu)(bu)知水垢的生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)成在(zai)不(bu)(bu)断影(ying)响着企业的能(neng)(neng)耗，吞(tun)噬着企业的利润(run)。

　　而且，单一为了降低清(qing)(qing)洗(xi)的(de)(de)费(fei)用，选(xuan)择了对设(she)备有损害和(he)腐蚀的(de)(de)清(qing)(qing)洗(xi)方法，或者没有资质和(he)业绩的(de)(de)小清(qing)(qing)洗(xi)公(gong)司，造成设(she)备的(de)(de)报废和(he)生产的(de)(de)停滞，付出了比清(qing)(qing)洗(xi)费(fei)用高几(ji)百倍(bei)甚至(zhi)上千倍(bei)的(de)(de)代价。每年定期(qi)检修对螺旋板换热器和(he)其他设(she)备进行清(qing)(qing)洗(xi)钝化保护处(chu)理，有着深远的(de)(de)经济价值和(he)环境影(ying)响(xiang)价值。
