集氣（煙）罩一般采用整體加工，包括過濾、集油、集水等設(shè)備，多為專業(yè)廚房公司制作。其外形應(yīng)統(tǒng)一、美觀、易于清理，廚房通風(fēng)中，需補(bǔ)充一定數(shù)量的新風(fēng)，一方面可以平衡氣壓，避免廚房負(fù)壓過大（一般不應(yīng)大于5pa），楊浦區(qū)廚房通風(fēng)排煙工程公司，另一方面可以降低廚房內(nèi)的溫度，改善工作環(huán)境。 </p> <p> 對于烹飪油煙的收集，采用的集氣（煙）罩主要有三種類別： </p> <p> （1）簡易不含擋油板和送風(fēng)設(shè)備的集氣罩適合各種靈活機(jī)動場所，便于加工安裝，價格便宜。但由于沒有送風(fēng)設(shè)備，集風(fēng)效果相對較差，容易使油煙在廚房工作人員面前回旋，并且容易造成油滴散落。 </p> <p> （2）含擋油板和送風(fēng)設(shè)備的集氣罩能夠較好地收集烹飪過程產(chǎn)生的油煙，楊浦區(qū)廚房通風(fēng)排煙工程公司，油滴不散落，只要送風(fēng)風(fēng)量合理，廚房操作人員工作面的空氣質(zhì)量就好，楊浦區(qū)廚房通風(fēng)排煙工程公司。但安裝要求較高，投資較大。 </p><div style="width:100%;text-align:

未定期清洗：油煙機(jī)在使用一段時間，油煙機(jī)葉輪、煙道上將粘有大量的油污，增加了葉輪的重量，這樣勢必增加了風(fēng)輪轉(zhuǎn)動動能，使電機(jī)起動電流加大。**機(jī)構(gòu)曾經(jīng)做過測試：長期未清洗的油煙機(jī)，在開機(jī)時的電流是正常值的3-6倍，這樣很容易燒毀電機(jī)，所以定期清洗油煙機(jī)，對電機(jī)是一個很好的保護(hù)作用，可以延長油煙機(jī)的使用壽命。油污粘住電機(jī)轉(zhuǎn)軸，加大了磨擦力，使電機(jī)負(fù)荷加大——費電。油污長期積累，發(fā)生氧化形成酸性物質(zhì)，對油煙機(jī)進(jìn)行腐蝕，生銹，加速油煙機(jī)老化。油污長期積累在油煙機(jī)內(nèi)部和煙道內(nèi)部，還將形成火災(zāi)***。葉輪、煙道上的油污增加了粘性，使排氣不暢通，增加了油煙在廚房空間上的擴(kuò)散，危害人們健康。

src="http://tyunfile.71360.com/UploadFile/shxianyu/637169547378476563/583528.jpg"></div><p> 如何計算廚房排風(fēng)量 </p> <p> 廚房排煙風(fēng)量計算與工廠、實驗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)量計算應(yīng)該以捕捉全部的油煙熱氣為基準(zhǔn)，不是*等同于簡單的通風(fēng)換氣。根據(jù)流體力學(xué)原理，對排煙罩吸排氣體的流動過程加以說明，這樣有助于計算方法的比較，也有助于對其他類型排煙設(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)為中心形成一個球形的等壓面，也稱作等速面。在這個等壓面上壓力的大小相等，壓力引起氣流的流動速度也相同，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)中心形成一個球形的等壓面，流速與到中心的距離的平方成反比，一個完全無遮擋的吸風(fēng)口，壓力傳播是整個球形空間，擴(kuò)散角為4*3.14159，由于流場為球形空間，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，要求大小尺寸合理的傘型罩子。
