1、附錄 附錄 C關(guān)于電旋風(fēng)除塵器模擬實(shí)驗(yàn)報(bào)告本文實(shí)驗(yàn)室的旋風(fēng)除塵器在標(biāo)度下對(duì)氣體流程領(lǐng)域做了一次詳細(xì)的實(shí)驗(yàn)性調(diào)查，從入口分離向排氣管輸送的報(bào)告。這個(gè)研究活動(dòng)的主要目的是對(duì)這些工業(yè)設(shè)備的復(fù)雜流程領(lǐng)域的研究來(lái)做一個(gè)完全的數(shù)據(jù)集，以便用 CFD 數(shù)字模仿更好的理解的檢驗(yàn)。作為工作的引伸，企圖被確定的一些設(shè)備的重要區(qū)域，在那里固相與氣相在相對(duì)滑動(dòng)速度下被分散，其起到分離作用。一般，氣體通過(guò)一臺(tái)離心通風(fēng)機(jī)被捕捉，其被開(kāi)閉環(huán)路控制。在管口流程線上被插

2、入一個(gè)流量測(cè)量計(jì)，用來(lái)測(cè)量氣體流量，由一個(gè)節(jié)流孔閥門(mén)控制著。在各個(gè)實(shí)驗(yàn)過(guò)程中，流量變化率在 1%之內(nèi)。旋風(fēng)除塵器在一個(gè)密閉的環(huán)路下別控制，被捕獲的固體顆粒通過(guò)排灰裝置被排出。有一部分的顆粒有被氣流帶走，接著到了一個(gè)袋式除塵器，是最后的氣體清洗階段。由于吹風(fēng)機(jī)引起的壓縮作用，可變的環(huán)流最基本的導(dǎo)致氣體發(fā)熱：類型 K（鋁鎳合金）的熱電偶被放在流量測(cè)量計(jì)上方的氣流流線上，它的作用是對(duì)該階段的氣流溫度的測(cè)量，當(dāng)達(dá)到熱平衡的條件時(shí)，可變的動(dòng)態(tài)分析

3、就可以實(shí)現(xiàn)了[10]。在旋風(fēng)除塵器的邊緣條件的氣流樣本的主要成分被 CFD 數(shù)據(jù)檢驗(yàn)并且進(jìn)行了分析，對(duì)主要的物理過(guò)程的更好的理解。結(jié)果各組成成分分別的被報(bào)告和分析。在操作條件 A 下，對(duì)旋風(fēng)除塵器入口和排氣管之間的環(huán)行空間進(jìn)行了速度測(cè)量，邊緣速度的測(cè)量，由于光學(xué)的可及性，從旋風(fēng)除塵器的頂蓋的產(chǎn)物是非常困難的，因?yàn)樗臄?shù)量級(jí)比切線方面要低。探針容量對(duì)準(zhǔn)線的任意偏差都是以一個(gè)正確的體積為基準(zhǔn)的，即使非常的小，導(dǎo)致不正確的測(cè)量，因?yàn)閺较蛏系那?/p>
