Basically, every kitchen needs smoke hood, which is a product that plays a vital role in our kitchen environment. However, if we don't clean up for a long time, it will have a lot of bad effects. We need to explore the details of this problem step by step! Then this article has prepared some basic cleaning methods of smoke exhaust equipment for you, hoping to be useful to you!

1、排風罩及前端油煙凈化器清洗

1. Cleaning of exhaust hood and front end oil fume purifier

防爆燈和紫外線燈可經常用濕抹布清洗。對于有擋水板、輸水風機、油網、濾網等前端凈化部件及防煙罩面板的，應先在油垢表面噴高溫燒堿水?；蛴脽龎A水浸泡，待污泥完全去除后用高壓水槍(清水)沖洗。

Explosion proof lamp and ultraviolet lamp can often be cleaned with wet cloth. For front-end purification components such as water baffle, water delivery fan, oil screen and filter screen and smoke hood panel, spray high-temperature caustic soda water on the oil dirt surface first. Or soak it in caustic soda water and wash it with high-pressure water gun (clean water) after the sludge is completely removed.

2、排氣管的清潔

2. Cleaning of exhaust pipe

排氣管組件：包括主管、防火閥、止回閥、調節(jié)閥、消聲管、柔性連接、彎頭、三通等。

Exhaust pipe components: including main pipe, fire damper, check valve, regulating valve, silencing pipe, flexible connection, elbow, tee, etc.

油煙管道清洗的要點是排煙口與通風柜的連接處，油煙管道內部與通風柜平行。這些地方需要清潔完整。清理管道轉彎處，如彎頭、三通等，必要時在彎頭上方打開。外部油煙管道每隔一季度清洗一次，但每季度只清洗一次管道彎頭。

The key point of oil fume pipeline cleaning is the connection between smoke exhaust outlet and fume hood, and the interior of oil fume pipeline is parallel to fume hood. These places need to be clean and complete. Clean the pipe bends, such as elbows and tees, and open them above the elbows if necessary. The external oil fume pipe shall be cleaned once every quarter, but the pipe elbow shall be cleaned only once every quarter.

3、排風機/通風柜清潔

通風柜部件：風機包括電機等部件。通風柜是把風機放在柜子里，包括風機和柜子。

Components of fume hood: fan includes motor and other components. The fume hood places the fan in the cabinet, including the fan and cabinet.

清洗時先將電機或風機葉片拆開，然后用刮刀將風機葉片上的油污和風機內的油渣清理干凈，再用脫脂劑清洗干凈，清洗后用清水沖洗干凈。

When cleaning, first disassemble the motor or fan blade, then clean the oil stain on the fan blade and the oil residue in the fan with a scraper, then clean it with degreasing agent, and then rinse it with clean water.

應清潔風扇的內部和外部，以防腐蝕。

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

4、后端煙氣凈化器清洗

煙氣凈化器部件：電機及煙氣處理系統(如過濾材料、靜電處理裝置、離心裝置等)

Components of flue gas purifier: motor and flue gas treatment system (such as filter material, electrostatic treatment device, centrifugal device, etc.)

清潔：根據油煙處理裝置的類型，進行相應的清潔工作，如更換過濾材料、清潔靜電處理裝置等。注：清潔酒店廚房排煙設備時，應該提前關閉帶電設備。

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

為了延長排煙設備的使用壽命，需要定期進行一些日常維護，如清洗風機、輸水風機、配水風機的表面污漬，保持管道通暢，保證輸水罐內水質清潔，避免控制油箱等缺油。

In order to prolong the service life of the smoke exhaust equipment, some routine maintenance needs to be carried out regularly, such as cleaning the surface stains of the fan, water delivery fan and water distribution fan, keeping the pipeline unobstructed, ensuring the clean water quality in the water delivery tank and avoiding the lack of oil in the control oil tank.
