如果油烟机是每天都开，而且油烟只从一个烟道出去，时间一长很快就会积满油污的，两三个月就已经能积起比较厚的一层油，有一指多厚，不及时对油烟机进行清洗，将会对正常使用产生较大的阻碍。

　　If the range hood is turned on every day and the oil fumes only go out from one flue, they will quickly accumulate oil stains over time. Within two or three months, a thick layer of oil can already accumulate, which is over a finger thick. If the range hood is not cleaned in time, it will cause significant obstacles to normal use.

　　因为怕出现烟道着火的事故，所以我们平时就经常把油烟管道清洗一下，把通烟口百叶窗的油洗掉，经常清洗，这样可能就会避免事故。所以这个具体看你这边的实际情况。也是根据当地消防部门要求定期清洗，如果是不太清楚，可以咨询我们艺源环保来公司帮你免费检测油烟机是不是需要清洗。

　　Because we are afraid of accidents such as flue fires, we often clean the oil fume ducts, wash off the oil from the louvers of the smoke vent, and clean them regularly to avoid accidents. So it depends on the actual situation on your end. It is also required by the local fire department to clean regularly. If you are not sure, you can consult our Yiyuan Environmental Protection company to help you check for free whether the range hood needs to be cleaned.

　　一、油烟管道清洗的介绍

　　1、 Introduction to cleaning oil fume ducts

　　油烟管道不经常清洗，会有很多油渍残留在烟机上和油烟管道表面，时间久了会形成油垢，简单的油烟管道清洗是处理不掉的，这样会影响油烟机、油烟管道清洗的使用，使烟流不易排除。

　　If the oil fume duct is not cleaned regularly, there will be a lot of oil stains remaining on the hood and the surface of the oil fume duct. Over time, oil stains will form. Simple cleaning of the oil fume duct cannot remove them, which will affect the use of the hood and oil fume duct cleaning and make it difficult to remove the smoke flow.

　　８０％左右的厨房排烟不畅，主要原因都是由于长时间没有对油烟净化器的内置过滤网清洁而而造成，油污堵塞过滤网而造成的，针对不同类型的油烟净化器有独特的方法。采用高压射流强力化油剂，对油烟管道清洗进行除油处理后，再做保养，使油烟气流明显好转，并形成保护膜使油渍不易残留在表面。

　　About 80% of kitchens have poor smoke exhaust, mainly due to long-term lack of cleaning of the built-in filter screen of the oil fume purifier, which is caused by oil pollution blocking the filter screen. There are unique methods for different types of oil fume purifiers. Using high-pressure jet powerful oil refining agent, after cleaning the oil fume pipeline and removing oil, maintenance is carried out to significantly improve the oil fume airflow and form a protective film to prevent oil stains from remaining on the surface.

　　油烟管道清洗内容包括烟罩表面、烟罩内的灯罩、排风口、排烟口以及电机、灶台表面。油烟管道清洗清洗的重点是排烟口与烟罩相连处并和烟罩同步平行的排油烟管道清洗。重点对平行油烟管道内部进行彻底清洁。采用的主要方法是专业人员进入油烟管道清洗内部进行清洁。对于排烟口窄小，人工无法进入油烟管道或由于油烟管道走身狭窄、人工触及不到无法进行清洁，但又存在着重大隐患的，本公司可利用特殊设备进行清洁，不留死角，并可拍摄清洁前后的对比照片，打消客户的疑虑和担心，消除一切潜在的火灾隐患。

　　The cleaning of oil fume ducts includes the surface of the hood, the lampshade inside the hood, the exhaust outlet, the smoke exhaust outlet, as well as the surface of the motor and stove. The key to cleaning the oil fume duct is to clean the exhaust duct that is connected to the smoke hood and runs parallel to the smoke hood. Focus on thoroughly cleaning the interior of parallel oil fume ducts. The main method used is for professionals to enter the oil fume duct and clean the interior. For narrow smoke exhaust outlets that cannot be manually entered into the oil fume duct, or for oil fume ducts that are too narrow to be manually touched and cannot be cleaned, but still pose significant risks, our company can use special equipment for cleaning, leaving no blind spots, and can take comparative photos before and after cleaning to dispel customers' doubts and concerns and eliminate all potential fire hazards.

　　风机、风柜与油烟管道连接的方法一般有两种情况：一种是用帆布相连的软连接，而另一种是直接与油烟管道相连的硬连接。可提供更换风机、风柜连接帆布的服务。如果是油烟管道硬连接，我们将与风机、风柜相连的油烟管道进行彻底清洁。

　　There are generally two methods for connecting fans, cabinets, and oil fume ducts: one is a soft connection using canvas, and the other is a hard connection directly connected to the oil fume duct. We can provide services for replacing fans and connecting canvas to wind cabinets. If it is a hard connection of the oil fume duct, we will thoroughly clean the oil fume duct connected to the fan and cabinet.

　　二、油烟管道清洗方法

　　2、 Cleaning methods for oil fume ducts

　　1、油烟管道清洗方法二：人工进入

　　1. Method 2 for cleaning oil fume ducts: manual entry

　　这种方法适用于大于40公分的平行烟道，人工钻进去清洗，该方法劳动强度比较大，要注意通风及配备低压照明用具。

　　This method is suitable for parallel flues larger than 40 centimeters, which can be manually drilled in for cleaning. This method has a relatively high labor intensity and requires attention to ventilation and the provision of low-pressure lighting fixtures.

　　2、油烟管道清洗方法三：拆卸

　　2. Oil fume duct cleaning method three: disassembly

　　当人工没有办法进入油烟管道时可采用拆卸法。这个方法是清洗最彻方法，但是施工难度比较大，需要的人工也很多，费用高。技术人员先根据烟道的实际情况，测算出拆卸的距离差，再两边延伸清洁。

　　When manual access to the oil fume duct is not possible, the dismantling method can be used. This method is the most thorough cleaning method, but the construction difficulty is relatively high, requiring a lot of labor and high cost. Technicians first calculate the distance difference for disassembly based on the actual situation of the flue, and then extend cleaning on both sides.

　　3、油烟管道清洗方法一：开孔

　　3. Method 1 for cleaning oil fume ducts: opening holes

　　这个方法比较容易，费用也比较低。需要技术人员先测算出需要开孔的间隔距离，开孔位置，开孔大小和开孔数量，再通过这些孔对油烟管道内进行清洗，最后再密封每个孔。开孔法是在人工法和拆卸法都无法清洗的时候用的。

　　This method is relatively easy and cost-effective. Technicians need to first measure and calculate the spacing distance, position, size, and quantity of openings required, and then clean the inside of the oil fume duct through these holes. Finally, seal each hole. The perforation method is used when neither manual nor disassembly methods can clean it.

　　4、油烟管道清洗方法四：机器设备清洗

　　4. Method 4 for cleaning oil fume ducts: Cleaning of machinery and equipment

　　人工不能进入，不方便拆卸，油污比较少，清洗周期较短的油烟管道可以用这个方法，这个方法难度最小，容易操作，且工作量最小，费用最低。在管道内喷洒清洗剂，油污软化后，再电动软轴刷刷干净。

　　This method can be used for oil fume ducts that cannot be manually entered, are inconvenient to disassemble, have less oil pollution, and have a shorter cleaning cycle. This method is the least difficult, easy to operate, requires the least amount of work, and has the lowest cost. Spray cleaning agent inside the pipeline, soften the oil stains, and then clean them with an electric soft shaft brush.

　　5、油烟管道清洗方法五：空降

　　5. Cleaning method five for oil fume ducts: airborne

　　这个方法主要适用于清洗50公分以上的竖油烟管道。管道的最上截和最下截先由技术人员拆开，技术人员系着安全绳从上而下清洗烟道内的污垢。这个方法比较危险，技术要求高，费用高，但清洗效果好。

　　This method is mainly suitable for cleaning vertical oil fume ducts over 50 centimeters. The top and bottom sections of the pipeline are first opened by technicians, who wear safety ropes to clean the dirt inside the flue from top to bottom. This method is quite dangerous, with high technical requirements and high costs, but the cleaning effect is good.

　　三、清洁必要性：

　　3、 The necessity of cleaning:

　　烟道、烟罩常年处于高温工作环境，油烟气化形成积油、积炭或油腻的胶状物，这三种物质非常容易引起火灾。若不经常清洗，积油越积越多，顺着烟罩自然倒流，不仅影响饭菜质量，而且还有损酒店信誉。同时，烟道中易寄生老鼠、蟑螂，不符合国家卫生标准。油腻胶状物长期扒附在金属表面，还会腐蚀金属材料，缩短烟道使用寿命。所以要定时进行油烟管道清洗，以免发生火灾危险。

　　Smoke ducts and hoods are exposed to high temperatures all year round, and the gasification of oil fumes can form oily, carbonaceous, or greasy gelatinous substances, which can easily cause fires. If not cleaned regularly, the accumulated oil will accumulate more and more, flowing back naturally along the hood, which not only affects the quality of the food, but also damages the hotel's reputation. Meanwhile, the smoke ducts are prone to parasitizing mice and cockroaches, which does not meet national hygiene standards. Long term adhesion of oily and sticky substances to metal surfaces can corrode metal materials and shorten the service life of the flue. So it is necessary to regularly clean the oil fume ducts to avoid the risk of fire.
