In the kitchen of each hotel, there are four groups of main smoke exhaust equipment: smoke hood, smoke exhaust pipe, smoke exhaust fan / cabinet and front and back-end oil fume purifiers. The smoke exhaust equipment of hotel kitchen is the equipment to discharge oil fume and keep the kitchen air fresh. After a long time of use, oil, smoke and other substances gather in the smoke hood and smoke exhaust pipe, which is easy to cause potential fire hazards. Next, Gao Lijie Zou Sheng, I will introduce the cleaning methods of these equipment.

一、排烟罩和前端油烟净化器的清洗方法

1、 Cleaning method of smoke exhaust hood and front end oil fume purifier

油烟进化器排烟罩和前端油烟净化器一般是设置为一体的。

The smoke exhaust hood of the fume evolution device and the front-end fume purifier are generally set as one.

部件：烟罩包含罩体和罩盖、防爆灯，前端净化器包括UV灯、川铁油网、运水烟罩等。

Components: the smoke hood includes cover body, cover and explosion-proof lamp. The front-end purifier includes UV lamp, Sichuan railway oil network, water transportation smoke hood, etc.

清洗方法：防爆灯、UV灯可以经常用湿抹布擦干净，含有挡水板、运水扇、油网、过滤网等前端净化部件的和排烟罩面板一样，都需要先将表面油垢铲干净，然后放在火碱水里泡，待油泥完全泡除后，再用高压水枪(清水)洗净。据经验证明，80%左右的厨房排烟不畅主要原因是油烟净化器的内置过滤网不洁堵塞。所以前端净化器的部件清洁是非常重要的

Cleaning method: the explosion-proof lamp and UV lamp can often be cleaned with a wet rag. The front-end purification parts including water baffle, water transport fan, oil screen, filter screen and so on, like the smoke exhaust hood panel, need to shovel the oil dirt on the surface first, and then soak it in caustic soda water. After the oil mud is completely soaked, wash it with a high-pressure water gun (clean water). According to experience, about 80% of the kitchen smoke exhaust is not smooth, mainly due to the unclean and blocked built-in filter screen of oil fume purifier. Therefore, it is very important to clean the components of the front-end purifier

二、排烟管道的清洗方法

2、 Cleaning method of smoke exhaust pipe

排烟管道.

Smoke exhaust duct

部件：包含主管道、防火阀、止回阀、调节阀、消音管道、软连接、弯头、三通等。

Components: including main pipe, fire damper, check valve, regulating valve, silencing pipe, soft connection, elbow, tee, etc.

清洗方法：油烟管道清洗是排烟口和烟罩相连处，和与烟罩平行的排油烟管道内部，这些地方需要清洗。清洗管道拐弯位置，例如弯头、三通，必要时在弯头上方开口。外部油烟管道每隔一个季度清洗一次，不过一个季度只需清洁管道弯头。

Cleaning method: the cleaning of oil fume pipe is the connection between the smoke outlet and the smoke hood, and the interior of the oil fume pipe parallel to the smoke hood. These places need to be cleaned. Clean the turning position of the pipeline, such as elbow and tee, and open the opening above the elbow if necessary. The external oil fume pipe shall be cleaned every other quarter, but only the pipe elbow needs to be cleaned every quarter.

三、排烟风机/风柜的清洗方法

3、 Cleaning method of smoke exhaust fan / air cabinet

风柜

Air cabinet

部件：风机包含电机等部件，风柜就是把风机放在柜子里，包含风机和柜体。

Components: the fan includes motor and other components. The fan cabinet is to put the fan in the cabinet, including the fan and cabinet body.

清洗方法：清洗时，先拆开电机或拆开电机扇叶，再用铲刀铲干净风机扇叶上的油污及风机里面的油渣，然后用除油剂清洗，洗完后再用清水冲洗干净。

Cleaning method: when cleaning, first disassemble the motor or the fan blade of the motor, then shovel the oil on the fan blade of the fan and the oil residue in the fan with a shovel, then clean it with degreasing agent, and then rinse it with clean water.

风机的内部和外部都要清洗，防止锈蚀。

The inside and outside of the fan shall be cleaned to prevent corrosion.

四、后端油烟净化器的清洗方法

4、 Cleaning method of rear end oil fume purifier

排空油烟净化器.

Drain the fume purifier

部件：电机和油烟处理系统（如滤料、静电处理装置、离心装置等）

Components: motor and oil fume treatment system (such as filter material, electrostatic treatment device, centrifugal device, etc.)

清洁：按照油烟处理装置的类型进行相应的清洁工作，如更换滤料，清洁静电处理装置等。注意：在清洗酒店厨房排烟设备时，带电的设备提前关掉电源。

Cleaning: carry out corresponding cleaning work according to the type of oil fume treatment device, such as changing filter material, cleaning electrostatic treatment device, etc. Note: when cleaning the smoke exhaust equipment in the hotel kitchen, the charged equipment shall be turned off in advance.

要想排烟设备使用寿命长，还需要定期做一些日常的保养：如清洁风机、运水扇、分水扇表面污渍，保持管道通畅，保证运水箱内水质洁净，避免控水箱缺油等等。

In order to prolong the service life of the smoke exhaust equipment, it is also necessary to do some daily maintenance regularly: such as cleaning the surface stains of the fan, water transport fan and water distribution fan, keeping the pipeline unobstructed, ensuring the clean water quality in the water transport tank, avoiding the lack of oil in the control tank, etc.

一旦发现任何反常现象，都要找到原因并及时。只有这样才能减少隐患，不耽误厨房的繁忙工作。

Once any abnormal phenomenon is found, find the reason and solve it in time. Only in this way can we reduce hidden dangers and not delay the busy work of the kitchen.
