由換熱器的損壞原因來看,腐蝕是一個(gè)十分重要的原因,而且換熱器的腐蝕是大量的普遍存在的,能夠解決好腐蝕問題,就等于解決了換熱器損壞的根本。要想防止換熱器的腐蝕,就得弄清楚腐蝕的根源,現(xiàn)就換熱器的腐蝕的原因從以下幾方面進(jìn)行討論。一、換熱器的用材的選擇：使用何種材料的決定因素是其經(jīng)濟(jì)性,管子材料有不銹鋼,銅鎳合金,鎳基合金,鈦和鋯等,除了工業(yè)上不能使用焊接管的情況以外都使用了焊接管,耐蝕材料*用于管程,殼程材料是碳鋼。二、換熱器的金屬腐蝕：金屬腐蝕的原理：金屬腐蝕是指在周圍介質(zhì)的化學(xué)或電化學(xué)的作用下,并且經(jīng)常是在和物理、機(jī)械或生物學(xué)因素的共同作用下金屬產(chǎn)生的破壞,也即金屬在它所處環(huán)境的作用下所產(chǎn)生破壞。換熱器幾種常見的腐蝕破壞類型：1、均勻腐蝕，在整個(gè)暴露于介質(zhì)的表面上,或者在較大的面積上產(chǎn)生的,宏觀上均勻的腐蝕破壞叫均勻腐蝕。2、接觸腐蝕，兩種電位不同的金屬或合金互相接觸,并浸于電解質(zhì)溶解質(zhì)溶液中,它們之間就有電流通過,電位正的金屬腐蝕速度降低,電位負(fù)的金屬腐蝕速度增加。3、選擇性腐蝕，合金中某一元素由于腐蝕,優(yōu)先進(jìn)入介質(zhì)的現(xiàn)象稱為選擇性腐蝕。4、孔蝕集中在金屬表面?zhèn)€別小點(diǎn)上深度較大的腐蝕稱為孔蝕。焊接式板式換熱器的優(yōu)點(diǎn)是什么？河南換熱器哪里有</p><p

背景技術(shù)：換熱器在石油、化工、垃圾處理等行業(yè)廣泛應(yīng)用。在燃煤鍋爐、垃圾焚燒爐等工藝中，排放的煙氣中含有大量粉塵和余熱，為了實(shí)現(xiàn)節(jié)能減排，常在煙氣管道上安裝換熱器來回收煙氣熱量。隨著使用時(shí)間的增加，煙氣中粉塵污垢會(huì)大量粘附在換熱器的表面，降低熱交換效果。所以需要經(jīng)常清洗換熱器，而長時(shí)間停機(jī)清洗換熱器會(huì)導(dǎo)致大量熱量損失。因此，需要研發(fā)一種能夠在線清洗的換熱器，來減小停機(jī)時(shí)間，減少熱量損失，保證熱交換效果。技術(shù)實(shí)現(xiàn)要素：本實(shí)用新型的目的是提供一種自清洗型換熱器，旨在解決上述現(xiàn)有技術(shù)中換熱器長時(shí)間運(yùn)行污垢粘附導(dǎo)致?lián)Q熱效果差，停機(jī)清洗時(shí)間長熱量損失大的技術(shù)問題。為解決上述技術(shù)問題，本實(shí)用新型所采取的技術(shù)方案是：一種自清洗型換熱器，包括換熱管、清洗系統(tǒng)及與煙道相連的殼體，所述換熱管為若干根、且并列設(shè)置在殼體內(nèi)，所述清洗系統(tǒng)設(shè)置于殼體及換熱管的外側(cè)，若干根換熱管的頂部均連通內(nèi)充待吸熱介質(zhì)的介質(zhì)進(jìn)管，若干根換熱管的底部均連通介質(zhì)出管；所述清洗系統(tǒng)包括噴淋管、輸送泵、清洗管路和清洗箱，內(nèi)充清洗液的清洗箱設(shè)置于殼體的底部、且與殼體連通。所述噴淋管上設(shè)有若干個(gè)朝向殼體內(nèi)換熱管的噴淋口。西藏?fù)Q熱器生產(chǎn)廠家</p></p><br
