在厨房设计中，排烟罩的选择是建立在厨房布局设计的基础上的，科学合理的设备布局，为排烟罩的选择提供了方便。排烟罩设计首先要确定类型、结构尺寸和安装位置，根据排烟罩计算排风量。所以，科学合理地设计排烟罩对系统运行效果和运行成本有很大的影响。济南酒店厨房排烟罩设应注意以下几点：

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:

选用型号。

Select the model.

排风罩的类型、结构形式，应根据烟气的类别和特点确定，排风罩应能有效捕集烟气。大型厨房设备尽量采用接收式排烟罩，靠明档的烧烤煎扒设备，应尽量选用带侧排烟的设备,则吸畑I距离汽气源近，受汽流扰动小，比上置的斗式排烟罩效率更高；

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;

节能设计与调试。

Energy-saving design and commissioning.

排风量计算应按防止烟气外逸的原则，通过计算确定。在保证吸排效果的前提下，尽量减小排烟罩罩口面积。用小的排风量达到好的控制效果，以较小的能耗有效捕集烟气。再通过风量平衡调试，做到罩内产生的负压首先保证排烟部位，在排烟罩设就要考虑到排烟风口设置位置。

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.

提高排烟效率。

Improve smoke exhaust efficiency.

尽量采用接收式排烟罩，罩口应尽可能接近烟气源，提高排烟效率。

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.

避开气流扰动。

Avoid airflow disturbance.

排烟罩应设置在避免气流干扰的位置，或采取有效措施避免气流扰动。在排烟罩旁有门窗，或气流直接穿过排烟罩，在避不开时，要采取规避措施。

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.

确定参数满足要求。

Confirm that the parameters meet the requirements.

排气罩罩口产生的负压区要大于烟气源，酒店厨房排烟罩设计扩大排烟的有效范围。

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.

封堵无效空隙。

Seal the void.

采用简单的封板封堵安装时产生的空当。如图9-19所示，由于柱体阻挡排烟罩贴墙安装，出现条缝，排烟罩需要按现场实际测虽的尺寸制作，工艺复杂，可以釆用条缝封板的方法减小无效吸气面积，提高排烟效率。

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.

足够的储气空间。

Enough gas storage space.

接收式斗式烟罩要有足够的储气空间，容纳爆锅或开启蒸柜时产生的大量烟气。当空间受到限制时，可釆取增加容气空间的措施。

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.

此外排烟罩的设置应做到方便人员操作和设备维修。根据排烟罩的大小，排风罩尽量釆用足够强度的不锈钢制作，酒店厨房排烟罩设计便于清除油烟产生的污油。还有什么问题就来我们网站http://www.jntfgd.com咨询吧！

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.
