style="text-indent:25px">煙囪是排風(fēng)排煙系統(tǒng)的排氣裝置。由于凈化后的氣體中仍然還含有一定濃度的污染物，這些污染物經(jīng)煙囪排放后在大氣中擴(kuò)散、稀釋?zhuān)⒊两档降孛?。為了保證地面污染物濃度不超過(guò)環(huán)境空氣質(zhì)從標(biāo)準(zhǔn)，煙囪必須具有一定的高度。此外，為了保證廢氣凈化系統(tǒng)能夠正常運(yùn)行，根據(jù)凈化處理對(duì)象的不同，在凈化系統(tǒng)中往往增設(shè)必要的輔助設(shè)備。例如：處理高溫氣體時(shí)的冷卻裝置、余熱利用裝置，滿足鋼材熱脹冷縮變化的管道補(bǔ)償器，輸送易燃易爆氣體時(shí)的防爆裝置，以及用來(lái)調(diào)節(jié)系統(tǒng)風(fēng)量和壓力平衡的各種閥門(mén)，用于測(cè)量系統(tǒng)內(nèi)各種參數(shù)的測(cè)量?jī)x器、控制儀器和測(cè)孔，用于支撐和固定管道、設(shè)備的支架，用于降低風(fēng)機(jī)噪聲的消音裝置等。</p><p style="text-indent:25px">排風(fēng)排煙系統(tǒng)設(shè)備的工作原理是將氣體中的污染物分離，變成無(wú)害的物質(zhì)，以達(dá)到凈化氣體的目的。塔體充填料是氣液兩相接觸的基本組成部分，屬于差動(dòng)觸頭逆流式。它提供了足夠的表面積來(lái)保持氣體流動(dòng)而不會(huì)產(chǎn)生太多的阻力。吸收劑是處理廢氣的主要介質(zhì)。根據(jù)不同廢氣的性質(zhì)選擇其性能和濃度。每單位氣體的消耗是通過(guò)計(jì)算吸收劑與惰性氣體摩爾流量的比值來(lái)確定的。吸入的廢氣是空氣管和通過(guò)填料層從上到下：循環(huán)吸收劑均勻地噴到包裝層通過(guò)液體分離器從塔頂和填料層的下表面流入循環(huán)水池。當(dāng)上升氣流與下吸塔在填料層中不斷接觸時(shí)，上升氣流中的流動(dòng)質(zhì)量濃度越來(lái)越低，達(dá)到塔頂?shù)呐欧艠?biāo)準(zhǔn)。排風(fēng)排煙系統(tǒng),借助燃?xì)饣蛉加偷容o佐燃料焚燒廢氣。</p><div

style="text-indent:25px">排風(fēng)排煙系統(tǒng)的常用吸附劑：活性炭具有孔穴豐富、比表面積大的優(yōu)點(diǎn)，適用于大部分VOCs的吸附凈化，但是當(dāng)廢氣濕度>60%時(shí)，其吸附效果會(huì)較大降低。除此之外，活性炭應(yīng)用于實(shí)際中常常會(huì)引發(fā)安全問(wèn)題，因其不穩(wěn)定性遇熱空氣會(huì)自燃起火，因此再生應(yīng)使用水蒸氣。在油漆的噴灑車(chē)間里面，無(wú)用的氣體潮濕程度rh在百分之八十五到百分之九十之間，假設(shè)用活性炭相關(guān)的材料進(jìn)行吸收，則必須把這些氣體先把水汽弄出去，操作流程非常不簡(jiǎn)單，所以該方法不建議采用。相對(duì)于活性炭，沸石吸附劑的特性為:不可燃；耐溫1000℃，可用熱空氣高溫再生；有較強(qiáng)的疏水性，當(dāng)廢氣濕度RH<90%時(shí)，表現(xiàn)出很好的VOCs吸附效果。排風(fēng)排煙系統(tǒng)力求運(yùn)行穩(wěn)定、費(fèi)用低、管理方便、維護(hù)容易，從而達(dá)到治理污染、保護(hù)環(huán)境的目的。通風(fēng)消防排煙系統(tǒng)批發(fā)價(jià)</p><p

style="text-indent:25px">排風(fēng)排煙系統(tǒng)安裝要注意哪些？不同的排放場(chǎng)合和不同的廢氣，有不同的工藝流程。但不論采取哪種工藝流程，都由如下工藝單元組成。廢氣預(yù)處理為了避免催化劑床層的堵塞和催化劑，廢氣在進(jìn)入床層之前必須進(jìn)行預(yù)處理，以除去廢氣中的粉塵、液滴及催化劑的毒物。在進(jìn)行催化燃燒的工藝設(shè)計(jì)時(shí)，應(yīng)根據(jù)具體情況，對(duì)于處量較大的場(chǎng)合，設(shè)計(jì)成分建式流程，即預(yù)熱器、反應(yīng)器裝設(shè)，其間用管道連接。對(duì)于處量小的場(chǎng)合，可采用催化焚燒爐把預(yù)熱與反應(yīng)組合在一起，但要注意預(yù)熱段與反應(yīng)段間的距離。在催化劑用量計(jì)算上，需要綜合考慮到催化劑的類(lèi)型、VOCs的組成、反應(yīng)溫度等因素，不能只參照某一因素考慮。催化劑選擇應(yīng)嚴(yán)謹(jǐn)。比如催化劑對(duì)含鹵素氣體要求較高，需優(yōu)先對(duì)該種廢氣進(jìn)行預(yù)處理，然而這樣會(huì)較大增加處理成本，因此要在工藝優(yōu)化、成本綜合計(jì)算之后才能確定催化劑。對(duì)于可能會(huì)導(dǎo)致催化劑毒的物質(zhì)，需要對(duì)毒物質(zhì)進(jìn)行預(yù)先去除。通風(fēng)消防排煙系統(tǒng)批發(fā)價(jià)</p><p
