廚房排煙罩是一種大型油煙凈化設備，它以傳質理論和兩種模式為基礎，利用撞擊、冷凝和吸附過濾技術凈化烹飪過程中的油霧和氣味等有害物質，在酒店廚房排煙中起到了重要的作用，那么大家知道它的通風能力和凈化原理嗎?下面濟南排煙罩廠家為您講解一番。

Kitchen smoke hood is a large-scale oil fume purification equipment. Based on mass transfer theory and two modes, it uses impact, condensation and adsorption filtration technology to purify harmful substances such as oil mist and odor in the cooking process. It plays an important role in hotel kitchen smoke exhaust. Do you know its ventilation capacity and purification principle? Next, Jinan smoke exhaust hood manufacturer will explain it to you.

排風罩在凈化設備中設有集氣體收集、洗滌、反應吸收、洗滌劑循環、機械過濾、氣體輸送、降溫、防火等結構單元，集氣體收集、凈化、輸送于一體;排煙罩是集、消防、于一體的多功能的油煙凈化設備。

The exhaust hood is provided with structural units in the purification equipment, including gas collection, washing, reaction absorption, detergent circulation, mechanical filtration, gas transmission, cooling and fire prevention, which integrates gas collection, purification and transmission; Smoke exhaust hood is a multifunctional oil fume purification equipment integrating environmental protection, fire protection and energy saving.

1.廚房排煙罩的通風能力：

1. Ventilation capacity of kitchen smoke exhaust hood:

(1)用消聲器降低風扇噪音。

(1) Use muffler to reduce fan noise.

(2)特制的高壓大風量專用高速風扇，足以擊潰雜亂的管道阻力。通風效果好。

(2) The special high-speed fan with high pressure and large air volume is enough to break up the disordered pipe resistance. Good ventilation effect.

(3)外接電機耐高溫、耐水蒸氣，可靠性也高。

(3) The external motor is resistant to high temperature, water vapor and high reliability.

2.凈化原理：

2. Purification principle:

(1)少量剩余油煙進入過濾桶進行二次凈化，固體顆粒沉積在濾料上，廢油精通道流入油箱。濾筒中的過濾材料可以輕松更換。

(1) A small amount of residual oil smoke enters the filter barrel for secondary purification, solid particles are deposited on the filter material, and the waste oil fine passage flows into the oil tank. The filter material in the filter cartridge can be easily replaced.

(2)在風機的抽吸作用下，油煙進入濾油器進行初步凈化，油煙的大部分灰粒和液滴被截留，廢油沿油路流入油箱，顆粒沉積在金屬濾油器上。機油濾清器易于拆卸和清潔。

(2) Under the suction of the fan, the oil fume enters the oil filter for preliminary purification. Most of the ash particles and liquid droplets of the oil fume are intercepted. The waste oil flows into the oil tank along the oil path, and the particles are deposited on the metal oil filter. The oil filter is easy to remove and clean.

(3)經排煙罩凈化的空氣通過風機和風管排室外。

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

Relevant precautions:

在人們的日常生活中，每個廚房都需要一個廚房排煙罩來保證廚房空氣的清新，所以廚房排煙罩是局部排煙的一種形式。在設計過程中，需要保證風帽處風速的穩定性。風量由罩口風速計算，得到廚房排煙罩所需的總風量。通過計算總風量來確定廚房排煙管的截面積。然后根據廚房整體高度確定管道高度。

In people's daily life, every kitchen needs a kitchen smoke exhaust hood to ensure the fresh air in the kitchen, so the kitchen smoke exhaust 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. The air volume is calculated by the wind speed at the hood mouth to obtain the total air volume required by the kitchen smoke hood. The cross-sectional area of the kitchen smoke exhaust pipe is determined by calculating the total air volume. Then determine the pipe height according to the overall height of the kitchen.

安裝廚房排煙罩時，記得處理漏油和漏氣。在處理過程中，為所有材料選擇耐火材料。管道安裝過程中設置防火閥，以確保廚房排煙罩在使用過程中發生火災后，防火閥應自動關閉，以防止甚燒毀營地的現象。

When installing the kitchen exhaust hood, remember to deal with oil and air leakage. Select refractory materials for all materials during treatment. Fire damper shall be set during pipeline installation to ensure that the fire damper shall be automatically closed after a fire occurs in the kitchen smoke hood during use to prevent even burning the camp.

廚房排風罩風機選型時應準確計算風道的風速、流量和風阻，以便在風機選型過程中準確確定風機的風量、風壓和電機功率。從而達到的良好效果，在日常運行中對降低成本起著關重要的作用。

The wind speed, flow and wind resistance of the air duct shall be accurately calculated during the selection of the kitchen exhaust hood fan, so as to accurately determine the air volume, pressure and motor power of the fan during the selection of the fan. So as to achieve the good effect of energy saving and play a vital role in reducing costs in daily operation.
