山東閉式冷卻塔產(chǎn)生腐蝕的原因介紹(山東 閉式冷卻塔生產(chǎn))

特菱閉式冷卻塔把各種配套設(shè)備全部放到塔內(nèi),比如管殼式換熱器,通過(guò)空氣和水、噴淋水和循環(huán)水熱交換保證降溫的效果,這種塔型不會(huì)產(chǎn)生較大的污染,因?yàn)槊芊馊忾],不與空氣接觸。那么在使用過(guò)程中產(chǎn)生腐蝕的原因又是哪些原因呢,詳細(xì)情況如下介紹。

特菱閉式冷卻塔整體塔型的材質(zhì)主要還是不銹鋼和鍍鋅鋼板為主,在使用不同材質(zhì)的過(guò)程中,,管板和列管之間有很大焊縫,這種焊縫會(huì)出現(xiàn)腐蝕泄漏現(xiàn)象,泄漏物進(jìn)入冷卻水系統(tǒng)會(huì)造成污染環(huán)境及物料的浪費(fèi)。閉式冷卻塔在制作時(shí),管板與列管的焊接一般采用手工電弧焊,焊縫形狀存在不同程度的缺陷,如凹陷、氣孔、夾渣等,焊縫應(yīng)力的分布也不均勻。使用時(shí)管板部分與工業(yè)冷卻水接觸,而工業(yè)冷卻水中的雜質(zhì)、鹽類(lèi)、氣體、微生物都會(huì)構(gòu)成對(duì)管板和焊縫的腐蝕。研究表明,工業(yè)水無(wú)論是淡水還是海水,都會(huì)有各種離子和溶解的氧氣,其中氯離子和氧的濃度變化,對(duì)金屬的腐蝕形狀起重要作用。另外,金屬結(jié)構(gòu)的復(fù)雜程度也會(huì)影響腐蝕形態(tài)。針對(duì)閉式冷卻塔防腐問(wèn)題,傳統(tǒng)方法以補(bǔ)焊為主,但補(bǔ)焊易使管板內(nèi)部產(chǎn)生內(nèi)應(yīng)力,難以消除,可能造成冷卻塔管板焊縫再次滲漏。現(xiàn)西方國(guó)家多采用高分子復(fù)合材料的方法進(jìn)行保護(hù)閉式冷卻塔的清洗與保養(yǎng)。

 

以上就是冷卻塔改造廠家廣東特菱節(jié)能空調(diào)為大家?guī)?lái)山東閉式冷卻塔產(chǎn)生腐蝕的原因介紹(山東 閉式冷卻塔生產(chǎn))的內(nèi)容,廣東特菱空調(diào)專(zhuān)業(yè)從事冷卻塔改造,冷卻塔維修,冷卻塔清洗,冷卻塔保養(yǎng),服務(wù)工業(yè)領(lǐng)域,產(chǎn)品包括玻璃鋼冷卻塔,工業(yè)冷卻塔等并提供全方位的冷卻塔改造方案,涵蓋深圳,廣州,珠海,惠州,東莞等,致力于打造變成優(yōu)質(zhì)的冷卻系統(tǒng)和配套設(shè)施服務(wù)項(xiàng)目的廠家。
