</p> <p> <span style="font-size:14px;"> （1）主排煙管道通風(fēng)面積不夠，氣體流速過大。根據(jù)工程經(jīng)驗(yàn)，排煙主管道內(nèi)風(fēng)速不能超過15m/s。否則在運(yùn)行一個(gè)時(shí)期以后（如一年以后）很容易造成排煙系統(tǒng)不通暢。在油煙凈化器的運(yùn)行實(shí)踐中，閔行區(qū)廚房通風(fēng)排煙專業(yè)公司，大部分案例都是因排煙管道通風(fēng)面積不足引起的不通暢，管道內(nèi)氣體的流速都在15m/s以上。</span> </p> <p> <span style="font-size:14px;"> （2）排煙管道由于要穿過建筑梁而使管道通風(fēng)截面積變小，截面上阻力增加，造成氣流不通暢。（3）排煙管道在穿過建筑梁或躲避其它設(shè)備管道時(shí)，排煙管道中的一段會(huì)低于整體排煙管道平面，閔行區(qū)廚房通風(fēng)排煙專業(yè)公司。在使用一段時(shí)間后，由于油水混合物會(huì)積聚在較低的那段排煙管道中，直接影響排煙通暢，閔行區(qū)廚房通風(fēng)排煙專業(yè)公司。 </span> </p> <p> <span style="font-size:14px;">（4）不同樓層的廚房油煙通過同一主管道排出，離出口近的樓層廚房排煙效果較好，而較低樓層的廚房排煙不通暢。</span> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

廚房排煙風(fēng)量計(jì)算與工廠、實(shí)驗(yàn)室排除有害氣體一樣，要把所產(chǎn)生的有害氣體全部排除干凈，屬于專業(yè)排煙技術(shù)。排煙風(fēng)量計(jì)算應(yīng)該以捕捉全部的油煙熱氣為基準(zhǔn)，不是*等同于簡(jiǎn)單的通風(fēng)換氣。根據(jù)流體力學(xué)原理，對(duì)排煙罩吸排氣體的流動(dòng)過程加以說明，這樣有助于計(jì)算方法的比較，也有助于對(duì)其他類型排煙設(shè)備進(jìn)行分析。 </p> <p> 排煙罩的排風(fēng)原理 </p> <p> 壓力的傳播和聲音的傳播是一樣的，在空氣中壓力也是以聲音的速度在傳播。氣體被吸入負(fù)壓區(qū)，形成氣流，以負(fù)壓區(qū)為中心形成一個(gè)球形的等壓面，也稱作等速面。在這個(gè)等壓面上壓力的大小相等，壓力引起氣流的流動(dòng)速度也相同，流線處處與球形等壓面垂直。在不同半徑的等壓面上，球形面積不同，流速不同，通過球形面積流量相等，也就是與吸風(fēng)口的流量相同。也就是以負(fù)壓區(qū)中心形成一個(gè)球形的等壓面，流速與到中心的距離的平方成反比，一個(gè)完全無遮擋的吸風(fēng)口，壓力傳播是整個(gè)球形空間，擴(kuò)散角為4*3.14159，由于流場(chǎng)為球形空間，所以流速衰變的特別快。吸風(fēng)口徑為do,當(dāng)吸風(fēng)口距離S=0.8do時(shí)流速就降為吸風(fēng)口流速uo的10%也就等于0.1uo，所以排煙罩的大小要考慮盡量靠近灶臺(tái)，要求大小尺寸合理的傘型罩子。
