style="text-indent:25px">鍋爐點(diǎn)火排汽消聲器（TB）型為控制高壓汽流排放噪聲，當(dāng)前世界上已具有多種形式的的消聲器，其原理大多采用多級(jí)節(jié)流降壓，由于其結(jié)構(gòu)復(fù)雜、重量大、難以解體檢修，因而限制了其應(yīng)用范圍。本新型結(jié)構(gòu)的消聲器克服了上述缺點(diǎn)。本型排汽消聲器系綜合了比較合理的消聲原理所設(shè)計(jì)。高壓蒸汽在排汽消聲器內(nèi)經(jīng)一次控流后進(jìn)入降壓體經(jīng)大容積擴(kuò)壓后，往往會(huì)因排汽偏離設(shè)計(jì)值等諸原因，使噪聲仍然高于標(biāo)準(zhǔn)值。為此，在降壓體外設(shè)計(jì)了一只雙層結(jié)構(gòu)的阻聲罩，連云港消聲器，它系根據(jù)降壓體所發(fā)出的剩余噪聲的頻譜特性所是設(shè)計(jì)，用以有效地吸收剩余噪聲，連云港消聲器，連云港消聲器。當(dāng)用戶按要求安裝后，總噪聲量要達(dá)36～42分貝。高頻噪音會(huì)隨著距離的增加或遇到障礙物而迅速衰減。連云港消聲器</p><div

空氣管道消音器是主要建立在“小孔噴注”理論結(jié)合阻抗擴(kuò)容吸聲的消音原理，鍋爐蒸汽排放一般流速快，氣流噪聲高，需先以通孔擴(kuò)流，經(jīng)過(guò)多次通孔后的蒸汽在抗性擴(kuò)張室得到降壓降流，氣流再經(jīng)小孔噴出，噴出后其各倍頻帶的聲功率已降低，而聲壓級(jí)的頻率被推高到20000Hz以上范圍，其噪聲大為削弱，但部分頻率的二次噪音還需要進(jìn)一步消音，我們?cè)跀U(kuò)張室外加裝阻性吸聲棉結(jié)構(gòu)，它系根據(jù) 降壓體所發(fā)出的剩余噪聲的頻譜特性所設(shè)計(jì)，用以有效地吸收剩余噪聲。當(dāng)用戶按要求安裝后，消音量可達(dá)30-42分貝。使之達(dá)到工業(yè)企業(yè)噪聲標(biāo)準(zhǔn)要求。 </p> <p> 空氣管道消音器也是一種利用渦流消音原理的消音器，與馬克沁消音器的區(qū)別是將膜片換成螺旋片，螺旋片中心開(kāi)有彈頭通道。 </p> <p> 吸熱消音原理 </p> <p>

每個(gè)企業(yè)所需要的消聲器是不同的是要根據(jù)自己所需的配套實(shí)施來(lái)計(jì)算所需的消聲器大小，消聲器的發(fā)明創(chuàng)造是通過(guò)必定的數(shù)據(jù)驗(yàn)算，而且不計(jì)其數(shù)的試驗(yàn)終究得來(lái)的，而且不同的場(chǎng)合使用的消聲器也是不同的，在這樣的基礎(chǔ)上應(yīng)該清晰的就是消聲器核算的過(guò)程中存在著壓力丟失，現(xiàn)在我們就來(lái)看下壓力丟失是怎么進(jìn)行核算的。 </p> <p> 風(fēng)機(jī)消聲器的壓力丟失包含兩個(gè)方面，也就是消聲器內(nèi)通道壁面和氣流矛盾所發(fā)生的矛盾壓力丟失，別的一種就是消聲器內(nèi)部架構(gòu)通道拐折、截面變化等導(dǎo)致氣流活動(dòng)狀況改變所發(fā)生的部分壓力丟失。 </p> <p> 在消聲器使用的過(guò)程中前面的部分丟失仍是占有主導(dǎo)地位的，導(dǎo)流管對(duì)部分丟失補(bǔ)償仍是很大的，這個(gè)時(shí)分核算能量損耗的話就是通過(guò)前后導(dǎo)流管出流的速度進(jìn)行比較的，也就是兩者之間的差值越大的話，樣例著壓力丟失也越大。 </p> <p> 在核算消聲器的壓力丟失的時(shí)分，其間不能忽視的一個(gè)概念就是消聲量，也就是風(fēng)機(jī)消聲器在聲學(xué)課程中是重要的目標(biāo)，一般采用的都是刺進(jìn)丟失進(jìn)行比較的，也就是在消聲器的前后、左右都進(jìn)行的聲源共同的時(shí)分進(jìn)行檢測(cè)，這個(gè)時(shí)分滿意的就是距離統(tǒng)一、方向共同、聲學(xué)環(huán)境也一樣的情況下檢測(cè)聲級(jí)之間的差值。

微穿孔板消聲器一般是用厚度小于1mm的純金屬薄板制作，在薄板上用孔徑小于1mm的鉆頭穿孔，穿孔率為1%一3%。選擇不同的穿孔率和板厚不同的腔深，就可以控制消音器的頻譜性能，使其在需要的頻率范圍內(nèi)獲得良好的消音效果。生產(chǎn)過(guò)程中如果產(chǎn)生較大的噪音，那么工人在這種情況下會(huì)心情煩躁，同時(shí)也影響他們的工作質(zhì)量和效率。連云港消音器安裝</p><p
