廚房內的排煙罩是為飲食開發的大型飲食油煙凈化設備，它是依據傳質雙模理論、選用磕碰、冷凝、吸收過濾的技術，凈化烹調過程中發作的油霧、氣味等有害物質。下面濟南酒店廚房排煙罩廠家來講講廚房排煙罩的通風能力以及凈化原理。

The smoke exhaust hood in the kitchen is a large-scale cooking oil fume purification equipment specially developed for catering. It is based on the dual-mode theory of mass transfer and the technology of bump, condensation, absorption and filtration to purify the oil mist, odor and other harmful substances that occur during cooking. Next, the manufacturer of kitchen smoke exhaust hood of Jinan Hotel will talk about the ventilation capacity and purification principle of kitchen smoke exhaust hood.

1、通風能力：

1. Ventilation capacity:

（1）配消聲器降低風機噪聲。

(1) Equipped with muffler to reduce fan noise.

（2）分外制作的專用高速轉速風機、壓力高、風量大，足以打敗凌亂管道的阻力。它的通風效果好。

(2) The special high-speed fan made by the company has high pressure and large air volume, which is enough to defeat the resistance of messy pipes. It has good ventilation effect.

（3）分外電機耐高溫、耐水汽，并且它的可靠性也高。

(3) The extra motor is resistant to high temperature, water and steam, and its reliability is also high.

2、凈化原理：

2. Purification principle:

（1）剩下少量的油煙再進入高能效過濾桶進行二次凈化，固態顆粒沉積在濾料上，廢油精槽道流入油盒。濾筒內濾料可便當的替換。

(1) The remaining small amount of oil fume enters the high-efficient filter barrel for secondary purification, solid particles are deposited on the filter material, and the waste oil fine channel flows into the oil box. The filter material in the filter cartridge can be easily replaced.

（2）在風機的抽吸力效果，油煙進入濾油柵進行初級凈化，大多數油煙的灰粒和液滴被截留，費油順油道流入油盒，顆粒沉積在金屬濾油柵上。濾油柵可以便當的取下清洗。

(2) In the suction effect of the fan, the oil fume enters the oil filter for primary purification, most of the ash particles and liquid droplets of the oil fume are intercepted, the waste oil flows into the oil box along the oil passage, and the particles are deposited on the metal oil filter. The oil strainer can be easily removed and cleaned.

（3）通過排煙罩凈化后的空氣經風機、氣管排向室外。

(3) The purified air through the smoke exhaust hood is discharged to the outside through the fan and air pipe.

在人們的日常生活中，每家的廚房都需要用廚房排煙罩來保障廚房空氣的清新，所以廚房排煙罩為局部排煙的一種形式。在設計過程須要確保罩口風速的穩定。通過罩口風速計算風量，從而得到廚房排煙罩的所需的總風量。通過總風量計算確定廚房排煙管道的橫截面積。再根據廚房整體高度確定管道高度。

In people's daily life, every kitchen needs to use a kitchen smoke hood to ensure the fresh air in the kitchen, so the kitchen smoke hood is a form of local smoke exhaust. In the design process, it is necessary to ensure the stability of the wind speed at the hood mouth. The air volume is calculated by the wind speed at the hood opening, and the total air volume required for the kitchen smoke exhaust hood is obtained. Determine the cross-sectional area of the kitchen smoke exhaust pipe through the total air volume calculation. Then determine the pipe height according to the overall height of the kitchen.

廚房排煙罩安裝切記漏油與漏風的處理。處理時所有材料一定要選用防火材料。在管道安裝過程中一定要設置防火閥，確保廚房排煙罩在使用過程中發生火災后防火閥應該自動閉，防止火燒連營的現象發生。

When installing the kitchen smoke exhaust hood, remember the treatment of oil and air leakage. All materials must be fireproof during treatment. The fire damper must be set during the installation of the pipeline to ensure that the fire damper should be closed automatically after the fire occurs in the use of the kitchen smoke exhaust hood, so as to prevent the phenomenon of burning the camp.

廚房排煙罩選用風機時應準確計算風管的風速、流量、風阻，這樣在選擇風機過程中能準確的確定風機的風量、風壓、電機功率。從而達到節能的良好效果，對日常經營中減低成本起到重中之重的作用。

When selecting the fan for the kitchen smoke exhaust hood, the wind speed, flow and wind resistance of the air duct should be accurately calculated, so that the air volume, air pressure and motor power of the fan can be accurately determined during the selection of the fan. So as to achieve a good effect of energy conservation and play a key role in reducing costs in daily operation.

此外排煙罩在凈化設備中設置了氣體收集、洗刷、反應吸收、洗刷劑循環、機械過濾器、氣體運送、降溫防火等結構單元，是集氣體的收集-凈化-運送于一體，您有相關需求就來我們網站http://www.159969.cn咨詢吧！

In addition, the smoke exhaust hood is equipped with gas collection, scrubbing, reaction absorption, scrubbing agent circulation, mechanical filter, gas transportation, cooling and fire prevention and other structural units in the purification equipment, which is a collection, purification and transportation of gas.
