1、運(yùn)水集氣(煙)罩：運(yùn)水集氣(煙)罩的設(shè)計(jì)原理是形成水幕循環(huán)，與油煙碰撞后達(dá)到凈化油煙的目的。影響運(yùn)水集氣(煙)罩使用效果的關(guān)鍵是要形成連續(xù)的水幕而只是形成了斷續(xù)流動(dòng)的水滴或小水柱，因此使用效果非常差。

　　1, the water transport gas (smoke) Hood: water transport gas (smoke) hood design principle is to form a water curtain cycle, and after soot collision, to achieve the purpose of soot purification. The key to influence the effectiveness of the water transport (gas) hood is to form a continuous water screen, but only to form intermittent water droplets or small water column, so the use effect is very poor.

　　2、使用運(yùn)水集氣(煙)罩的優(yōu)點(diǎn)是能夠在集氣(煙)罩處除掉部分油煙，減輕油煙凈化設(shè)備的處理負(fù)荷，提高系統(tǒng)的凈化效果。但如果運(yùn)水集氣(煙)罩的過(guò)煙縫隙較窄，容易引起排煙系統(tǒng)不通暢。

　　2, the advantages of using the water collection gas (smoke) cover is to remove part of the soot in the gas collection hood, reduce the handling load of soot purification equipment, and improve the purification effect of the system. But if the exhaust gas collector (smoke) cover of the smoke gap is narrow, easy to cause smoke exhaust system is not smooth.

　　3、濟(jì)南排煙罩的設(shè)計(jì)對(duì)于排煙系統(tǒng)具有重要的影響。集氣罩設(shè)計(jì)不合理就很容易造成整個(gè)排煙系統(tǒng)不暢。引起排煙系統(tǒng)不通暢的因素有：

　　The design of /3 and gas collecting hood has important influence on smoke exhaust system. The design of the gas collecting hood is unreasonable, and it is easy to cause the whole smoke exhaust system to be impeded. There are some factors causing the smoke exhaust system to be unblocked:

　　1)油板間或者運(yùn)水集氣(煙)罩縫隙過(guò)小，這種情況較多;

　　1) the gap between the oil plate and the water collection gas (smoke) cover is too small, this situation is more;

　　2)煙罩內(nèi)收集油煙的開(kāi)口總的截面積太小而引起整體排煙不通暢;

　　2) the opening of the smoke collecting hood in the smoke hood is too small, so that the integral smoke exhaust is not unobstructed;

　　3)開(kāi)口分布不合理或是開(kāi)口沒(méi)有隨著與主管道的距離增大而增大，從而引起局部排煙不通暢。

　　3) the opening distribution is unreasonable or the opening does not increase with the distance between the main pipe and the main pipe, thus causing partial smoke exhaust is not smooth.

　　4、簡(jiǎn)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(dòng)場(chǎng)所，便于加工安裝，便宜。但由于沒(méi)有送風(fēng)設(shè)備，集風(fēng)效果相對(duì)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。

　　4 、 simple air hood without oil baffle and air supply equipment is suitable for all kinds of flexible and flexible place, easy to process and install, and the price is cheap. But because there is no air supply equipment, the effect of collecting air is relatively poor, it is easy to make the oil smoke whirl in front of the kitchen staff, and easy to cause oil droplets scattered.

　　5、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(guò)程產(chǎn)生的油煙，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。但安裝要求較高，投資較大。

　　5. The gas collecting hood with oil baffle and air supply device can better collect the smoke produced by cooking process, and the oil drops are not scattered. As long as the air supply volume is reasonable, the air quality of the working face of the kitchen operator is good. But the installation requirements are higher and the investment is larger.
