在廚房設計中，排煙罩的選擇是建立在廚房布局設計的基礎上的，科學合理的設備布局，為排煙罩的選擇提供了方便。排煙罩設計首先要確定類型、結構尺寸和安裝位置，根據(jù)排煙罩計算排風量。所以，科學合理地設計排煙罩對系統(tǒng)運行效果和運行成本有很大的影響。濟南酒店廚房排煙罩設應注意以下幾點：

In the kitchen design, the selection of smoke exhaust hood is based on the kitchen layout design. Scientific and reasonable equipment layout provides convenience for the selection of smoke exhaust hood. In the design of smoke exhaust hood, the type, structural size and installation position shall be determined first, and the exhaust air volume shall be calculated according to the smoke exhaust hood. Therefore, scientific and reasonable design of smoke exhaust hood has a great impact on the system operation effect and operation cost. The following points should be noted when designing the kitchen smoke exhaust hood of Jinan Hotel:

選用型號。

Select the model.

排風罩的類型、結構形式，應根據(jù)煙氣的類別和特點確定，排風罩應能有效捕集煙氣。大型廚房設備盡量采用接收式排煙罩，靠明檔的燒烤煎扒設備，應盡量選用帶側排煙的設備,則吸畑I距離汽氣源近，受汽流擾動小，比上置的斗式排煙罩效率更高；

The type and structural form of exhaust hood shall be determined according to the category and characteristics of flue gas, and the exhaust hood shall be able to effectively capture flue gas. Large-scale kitchen equipment should use the receiving smoke hood as far as possible, and the barbecue and grill equipment with open file should be used as far as possible, and the equipment with side smoke exhaust should be used as far as possible, so the smoke hood I is close to the steam source, less disturbed by steam flow, and more efficient than the upper bucket smoke hood;

節(jié)能設計與調(diào)試。

Energy-saving design and commissioning.

排風量計算應按防止煙氣外逸的原則，通過計算確定。在保證吸排效果的前提下，盡量減小排煙罩罩口面積。用小的排風量達到好的控制效果，以較小的能耗有效捕集煙氣。再通過風量平衡調(diào)試，做到罩內(nèi)產(chǎn)生的負壓首先保證排煙部位，在排煙罩設就要考慮到排煙風口設置位置。

The exhaust air volume shall be calculated according to the principle of preventing smoke from escaping. On the premise of ensuring the effect of suction and exhaust, the area of smoke exhaust hood shall be reduced as much as possible. Use small exhaust air volume to achieve good control effect, and effectively capture flue gas with small energy consumption. Then, through the air volume balance commissioning, the negative pressure generated in the hood should first ensure the key smoke exhaust parts, and the location of the smoke exhaust outlet should be considered when designing the smoke exhaust hood.

提高排煙效率。

Improve smoke exhaust efficiency.

盡量采用接收式排煙罩，罩口應盡可能接近煙氣源，提高排煙效率。

The receiving smoke exhaust hood shall be used as far as possible, and the hood mouth shall be as close to the smoke source as possible to improve the smoke exhaust efficiency.

避開氣流擾動。

Avoid airflow disturbance.

排煙罩應設置在避免氣流干擾的位置，或采取有效措施避免氣流擾動。在排煙罩旁有門窗，或氣流直接穿過排煙罩，在避不開時，要采取規(guī)避措施。

The smoke exhaust hood shall be set at the position to avoid airflow disturbance, or effective measures shall be taken to avoid airflow disturbance. There are doors and windows beside the smoke exhaust hood, or the airflow directly passes through the smoke exhaust hood. When it cannot be avoided, take evasive measures.

確定參數(shù)滿足要求。

Confirm that the parameters meet the requirements.

排氣罩罩口產(chǎn)生的負壓區(qū)要大于煙氣源，酒店廚房排煙罩設計擴大排煙的有效范圍。

The negative pressure area generated by the exhaust hood mouth is larger than the smoke source. The design of the hotel kitchen exhaust hood expands the effective range of smoke exhaust.

封堵無效空隙。

Seal the void.

采用簡單的封板封堵安裝時產(chǎn)生的空當。如圖9-19所示，由于柱體阻擋排煙罩貼墻安裝，出現(xiàn)條縫，排煙罩需要按現(xiàn)場實際測雖的尺寸制作，工藝復雜，可以釆用條縫封板的方法減小無效吸氣面積，提高排煙效率。

A simple sealing plate is used to block the gap generated during installation. As shown in Figure 9-19, because the column blocks the installation of the smoke exhaust hood against the wall, there are cracks. The smoke exhaust hood needs to be made according to the actual size measured on the site, and the process is complex. The method of seam sealing can be used to reduce the ineffective suction area and improve the smoke exhaust efficiency.

足夠的儲氣空間。

Enough gas storage space.

接收式斗式煙罩要有足夠的儲氣空間，容納爆鍋或開啟蒸柜時產(chǎn)生的大量煙氣。當空間受到限制時，可釆取增加容氣空間的措施。

The receiving bucket smoke hood shall have enough air storage space to accommodate a large amount of smoke generated when the boiler explodes or the steam cabinet is opened. When the space is limited, measures can be taken to increase the gas capacity space.

此外排煙罩的設置應做到方便人員操作和設備維修。根據(jù)排煙罩的大小，排風罩盡量釆用足夠強度的不銹鋼制作，酒店廚房排煙罩設計便于清除油煙產(chǎn)生的污油。還有什么問題就來我們網(wǎng)站http://www.rootsensor.com咨詢吧！

In addition, the smoke exhaust hood shall be set to facilitate personnel operation and equipment maintenance. According to the size of the smoke exhaust hood, the exhaust hood shall be made of stainless steel with sufficient strength as far as possible. The design of the smoke exhaust hood in the hotel kitchen is convenient to remove the dirty oil generated by the oil smoke.
