It's troublesome to block the oil smoke pipe. The kitchen is full of oil smoke and it's smoky. So, how to dredge the oil fume pipeline? Beijing Decoration Network Xiaobian tells you about the cleaning method of oil fume pipeline and how often it is cleaned. 1. Cleaning method of oil fume pipeline 1. Cleaning method of oil fume pipeline 2: Manual entry This method is suitable for parallel flue larger than 41 cm, and manual drilling is used for cleaning. This method is labor intensive, so attention should be paid to ventilation and low-voltage lighting equipment 2. Cleaning method of oil fume pipeline 3: Dismantling. When there is no way for manual entry into the oil fume pipeline, the disassembly method can be used. This method is the most thorough cleaning method, but it is difficult to construct, requires a lot of labor and costs a lot. Technicians first calculate the distance difference of disassembly according to the actual situation of the flue, and then extend the two sides to clean. 3. Cleaning method of oil fume pipeline 1: This method of opening holes is relatively easy and the cost is relatively low. Technicians are required to calculate the interval distance, opening position, opening size and opening number, and then clean the oil fume pipeline through these holes, and finally seal each hole. Opening method is used when manual method and disassembly method cannot be cleaned. 4. Cleaning method 4 of oil fume pipeline: The cleaning of machinery and equipment cannot be entered manually, so it is inconvenient to disassemble, and the oil fume pipeline with less oil pollution and short cleaning cycle can use this method. This method is the least difficult, easy to operate, and has the least workload and the lowest cost. Spray cleaning agent in the pipeline, and after the oil stain softens, clean it with electric flexible shaft brush. 5. Cleaning method of oil fume pipeline 5: Airborne this method is mainly suitable for cleaning vertical oil fume pipelines over 51 cm. The top and bottom sections of the pipeline are disassembled by technicians, who wear safety ropes to clean the dirt in the flue from top to bottom. This method is dangerous, with high technical requirements and high cost, but the cleaning effect is good.
