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、排煙罩和前端油煙凈化器的清洗方法

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

油煙進化器排煙罩和前端油煙凈化器一般是設置為一體的。

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

部件：煙罩包含罩體和罩蓋、防爆燈，前端凈化器包括UV燈、川鐵油網、運水煙罩等。

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：防爆燈、UV燈可以經常用濕抹布擦干凈，含有擋水板、運水扇、油網、過濾網等前端凈化部件的和排煙罩面板一樣，都需要先將表面油垢鏟干凈，然后放在火堿水里泡，待油泥完全泡除后，再用高壓水槍(清水)洗凈。據經驗證明，80%左右的廚房排煙不暢主要原因是油煙凈化器的內置過濾網不潔堵塞。所以前端凈化器的部件清潔是非常重要的

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、排煙管道的清洗方法

2、 Cleaning method of smoke exhaust pipe

排煙管道.

Smoke exhaust duct

部件：包含主管道、防火閥、止回閥、調節閥、消音管道、軟連接、彎頭、三通等。

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

清洗方法：油煙管道清洗是排煙口和煙罩相連處，和與煙罩平行的排油煙管道內部，這些地方需要清洗。清洗管道拐彎位置，例如彎頭、三通，必要時在彎頭上方開口。外部油煙管道每隔一個季度清洗一次，不過一個季度只需清潔管道彎頭。

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、排煙風機/風柜的清洗方法

3、 Cleaning method of smoke exhaust fan / air cabinet

風柜

Air cabinet

部件：風機包含電機等部件，風柜就是把風機放在柜子里，包含風機和柜體。

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：清洗時，先拆開電機或拆開電機扇葉，再用鏟刀鏟干凈風機扇葉上的油污及風機里面的油渣，然后用除油劑清洗，洗完后再用清水沖洗干凈。

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.

風機的內部和外部都要清洗，防止銹蝕。

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

四、后端油煙凈化器的清洗方法

4、 Cleaning method of rear end oil fume purifier

排空油煙凈化器.

Drain the fume purifier

部件：電機和油煙處理系統（如濾料、靜電處理裝置、離心裝置等）

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

清潔：按照油煙處理裝置的類型進行相應的清潔工作，如更換濾料，清潔靜電處理裝置等。注意：在清洗酒店廚房排煙設備時，帶電的設備提前關掉電源。

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.

要想排煙設備使用壽命長，還需要定期做一些日常的保養：如清潔風機、運水扇、分水扇表面污漬，保持管道通暢，保證運水箱內水質潔凈，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.

一旦發現任何反?，F象，都要找到原因并及時解決。只有這樣才能減少隱患，不耽誤廚房的繁忙工作。

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.
