回填土回填土實(shí)際就是用于填充埋地?fù)Q熱器與地層之間得填充材料。填充到鉆井內(nèi)，包裹在鉆井周圍不但可以起到固定U型管，防止污染物向深井泄漏與各含水層之間水的滲透，而且還應(yīng)促進(jìn)埋地?fù)Q熱器的傳熱[10][11]。不同的回填土導(dǎo)熱系數(shù)不同，原則上是導(dǎo)熱系數(shù)大的有利于埋地?fù)Q熱器傳熱。若比土壤導(dǎo)熱系數(shù)大得很多，U型管內(nèi)的循環(huán)水的熱量能及時通過回填土擴(kuò)散到土壤中，但土壤不能來不及向周圍擴(kuò)散，導(dǎo)致熱量都聚集在鉆井周圍。從而，選擇回填土必須考慮與土壤的匹配。本節(jié)對深度相同的60mA井、B井與62mG井進(jìn)行回填土的實(shí)驗(yàn)研究。60m的A井與B井的埋管都采用高密度聚乙烯(HDPE-100)，62mG井埋管采用HDPE-80，分別回填了50％膨潤土50％的泥漿與100％泥漿，純水泥和重量比為5％的膨潤土粉，經(jīng)測定三者的導(dǎo)熱系數(shù)分別為、與。循環(huán)水的流速設(shè)定為，分別對各井做了三組熱響應(yīng)實(shí)驗(yàn)。分析回填土對鉆井的傳熱率的影響，為選擇與土壤導(dǎo)熱相匹配的回填土提供參考意見。對于兩個其它條件相同的A井與B井，回填土對鉆井的熱阻與傳熱率的影響比較明顯。導(dǎo)熱系數(shù)大的回填土促進(jìn)鉆孔的傳熱。如圖1-12所示，A井的傳熱率大于B井的傳熱率。如圖1-13所示，導(dǎo)熱系數(shù)小的熱阻較大，影響熱量的傳遞。板式換熱器清洗方便嗎？</p><div

對碳鋼、低合金鋼、銅合金和某些牌號的不銹鋼而言,熔解氧是影響它們在水中腐蝕行為的**重要因素。其他溶解氣體在水中無氧時CO2將導(dǎo)致銅和鋼的腐蝕,但不促進(jìn)鋁的腐蝕。微量的氨腐蝕銅合金,但對鋁和鋼沒有影響。H2S促進(jìn)銅和鋼的腐蝕,但對鋁無影響。SO2降低了水的pH值,增加了水對金屬的腐蝕性。硬度一般說來,淡水的硬度增高對銅、鋅、鉛和鋼等金屬的腐蝕減小。非常軟的水腐蝕性很強(qiáng),在這種水中,不宜用銅、鉛、鋅。相反,鉛在軟水中耐蝕,在硬度高的水中產(chǎn)生孔蝕。pH值鋼在pH>11的水中腐蝕較小,pH<7時腐蝕增大。離子的影響氯離子可以破壞不銹鋼等鈍化金屬的表面,誘發(fā)孔蝕或。垢的影響淡水中的CaCO3垢。CaCO3垢層對傳熱不利,但是有利于防止腐蝕。4·傳熱過程對腐蝕的影響金屬在有傳熱和沒有傳熱的條件下,腐蝕行為是不相同的。一般說來,傳熱使金屬的腐蝕加劇,特別是在有沸騰、汽化或過熱的條件下更明顯。在不同介質(zhì)中,或?qū)Σ煌慕饘?傳熱的影響也不相同。5·防腐方法知道了換熱器各種腐蝕的原因,合理的選擇防腐措施,才能達(dá)到***利用設(shè)備的目的。折疊防護(hù)針對以上討論的有關(guān)腐蝕情況,提出以下防腐方法:這里主要介紹緩蝕劑,電化學(xué)保護(hù)。海南板式換熱器哪個品牌好</p></p><br
