The manufacturer of the exhaust hood says that the gas (smoke) hood is usually handled through the entire process, including filtration, oil collection, water collection and other equipment. Shape should be uniform, beautiful and easy to clean. This is a product that every user needs to use. There are three main types. What is it? Let's introduce it to the manufacturer of exhaust hood!

　?。?）機罩簡單，無油吊索和供氣設備，適用于各種靈活的操縱場所，易于加工和安裝，便宜。 然而，由于缺少空氣供應設備，集風效果相對較差，并且容易使煙灰在廚房工作人員面前旋轉，并且容易引起油滴飛散。

　　(1) The hood is simple, oil-free sling and air supply equipment, suitable for various flexible control places, easy to process and install, and cheap. However, due to the lack of air supply equipment, the effect of collecting air is relatively poor, and it is easy to make soot rotate in front of kitchen staff, and easy to cause oil droplets to disperse.

　?。?）帶有擋油板和供氣裝置的集氣罩可以更好地收集烹飪過程中產(chǎn)生的油煙，油滴不會散落。 只要送風量合理，廚房操作員工作表面的空氣質量就良好。 但是，安裝要求較高，投資較大。

　　(2) Gas collecting hood with oil baffle and gas supply device can better collect cooking fumes and oil droplets will not scatter. As long as the air supply is reasonable, the air quality on the working surface of the kitchen operator will be good. However, the installation requirements are higher and the investment is larger.

　?。?）集水收集（煙）罩

　　(3) Water collection (smoke) cover

　　集水（煙）罩的設計原理是形成水幕循環(huán)，達到與油煙碰撞后凈化煙灰的目的。 影響集水（煙）罩使用的關鍵是形成連續(xù)的水幕并定期清潔循環(huán)水系統(tǒng)。 實際上，由于管理不善，目前大多數(shù)集水（煙）罩不能形成連續(xù)的水幕，而只能形成斷續(xù)的水滴或小的水柱，因此效果非常差。

　　The design principle of collecting water (smoke) cover is to form water curtain circulation to purify soot after collision with oil fume. The key to affect the use of water catchment (smoke) cover is to form a continuous water curtain and regularly clean the circulating water system. In fact, due to poor management, most of the current catchment (smoke) cover can not form a continuous water curtain, but can only form intermittent droplets or small water column, so the effect is very poor.

　　使用集水氣（煙）罩的優(yōu)點是可以去除集氣（煙）罩上的部分煙灰，減輕煙灰凈化裝置的處理負荷，提高系統(tǒng)凈化效果。 但是，如果通過集水（煙）罩的煙氣的間隙狹窄，則容易使排氣系統(tǒng)暢通。

　　The advantage of using water collecting gas (smoke) cover is that it can remove part of the soot on the gas collecting (smoke) cover, reduce the processing load of the soot purification device, and improve the purification effect of the system. However, if the gap of the smoke passing through the water collecting hood is narrow, the exhaust system will be easily unobstructed.

　　排氣罩的制造商說，介紹了氣體收集（煙）罩的類型。 你聽得懂么？ 希望可以幫到您！
