One, the introduction of grease duct cleaning
Grease ducts are not often cleaned, there will be a lot of grease residue on the hood and the surface of the grease ducts, over time will form grease, simple grease duct cleaning is not dealt with, which will affect the use of the hood, grease duct cleaning, so that the smoke flow is not easy to exclude.
About 80% of the kitchen exhaust smoke is not smooth, the main reason is due to a long time no built-in filter cleaning of the oil smoke purifier and caused by oil clogging filter and caused by different types of oil smoke purifier has a unique method. The use of high-pressure jet powerful oiling agent, grease duct cleaning for oil removal treatment, and then do maintenance, so that the oil smoke air flow significantly better, and the formation of a protective film so that the oil stains are not easy to remain on the surface.
The contents of the grease duct cleaning include the surface of the fume hood, the lampshade inside the fume hood, the air vent, the smoke vent and the motor, the surface of the stove. Smoke pipe cleaning cleaning focus is the exhaust smoke outlet and hood connected to and synchronized with the hood parallel smoke pipe cleaning. The main focus is to thoroughly clean the inside of the parallel grease ducts. The main method used is for professionals to enter the interior of the grease duct to clean it. For the exhaust port is narrow, artificial can not enter the oil smoke pipe or due to the oil smoke pipe walk body is narrow, artificial reach can not be cleaned, but there is a major hidden danger, the company can use special equipment to clean, leaving no dead ends, and can be photographed before and after the cleaning of the comparison photos, to dispel customer doubts and concerns, to eliminate all the potential fire hazards.
There are generally two ways of connecting fans, air cabinets and grease ducts: one is a soft connection connected with canvas, while the other is a hard connection connected directly to the grease duct. Replacement of canvas connection for fans and cabinets is available. In case of hard connection of grease ducts, we will thoroughly clean the grease ducts connected to fans and air cabinets.
Two, grease duct cleaning methods
1, grease duct cleaning method two: manual entry
This method applies to parallel flue greater than 40 centimeters, manual drilling in the cleaning, the method is more labor-intensive, pay attention to the ventilation and equipped with low-voltage lighting appliances.
2, grease duct cleaning method three: demolition
When there is no way to manually enter the grease duct can be used to disassemble the method. This method is the most thorough method of cleaning, but the construction is difficult, requires a lot of labor, high cost. Technicians first according to the actual situation of the flue, measured the demolition of the distance difference, and then extended on both sides of the cleaning.
3, grease duct cleaning method one: open hole
This method is easier and less expensive. Technicians need to measure the distance between the holes to be opened, the location of the holes, the size of the holes and the number of holes to be opened, and then clean the inside of the grease ducts through these holes, and then finally seal each hole. The hole-opening method is used when neither the manual method nor the dismantling method can be cleaned.
4, grease duct cleaning method four: machine and equipment cleaning
Artificial can not enter, not easy to dismantle, less oil, cleaning cycle shorter grease ducts can be used in this method, this method is the least difficult, easy to operate, and the minimum amount of work, the lowest cost. Spray cleaning agent in the pipe, the oil is softened, and then electric flexible shaft brush brush clean.
5, the oil pipe cleaning method five: airborne
This method is mainly suitable for cleaning more than 50 centimeters of vertical oil pipe. The top and bottom sections of the pipe are first dismantled by the technician, who is tied to a safety rope to clean the dirt in the pipe from above and below. This method is more dangerous, technically demanding and expensive, but the cleaning effect is good.
Three, the need for cleaning:
Flue, hood is always in a high-temperature working environment, soot aerosol formation of oil, carbon or greasy gel, these three substances are very easy to cause a fire. If not often cleaned, the accumulation of oil more and more, along the hood natural backflow, not only affect the quality of meals, but also damage the hotel's reputation. At the same time, the flue is easy to parasitic rats, cockroaches, does not meet national health standards. Greasy gelatinous material attached to the metal surface for a long time, but also corrosion of metal materials, shortening the life of the flue. Therefore, it is necessary to carry out regular cleaning of the fume pipe to avoid fire hazards.
1, cleaning tools:
High-pressure water gun, kerosene, drill, cap top gun, cap top, gloves, steel wire ball, spatula, long shovel, spool, plate, pliers, dowel cutter, overalls, water shoes.
2, cleaning content:
Cleaning content includes the fume hood surface, fume hood inside the lampshade, water transport system, fire net, grease duct cleaning, grease purifier cleaning, fan cleaning, environmental protection net cleaning, wind turbine cleaning smoke outlet, and the surface of the stove. The key part of the cleaning is through the smoke vent and hood synchronized parallel to the exhaust pipe.
What to pay attention to the cleaning of the oil pipe
A, the kitchen because of the long-term use of open fire, easy to be fumigated by fumes, long-term not cleaned resulting in a lot of grease stains adhering to the hood and the surface of the flue to form grease and grime. It is recommended that places with a kitchen, every two months to thoroughly clean the hood, remove grease and other dirt and other fire hazards in a timely manner, to avoid high temperatures in the kitchen caused by fire. Cleaning must be a professional grease duct cleaning company thoroughly cleaned.
Two, the use of grease duct cleaning phone qualified kitchen building materials. The fire department found in the inspection, some small restaurants in order to save costs, with flammable materials to make chimneys and hood pipes. Once the frying pan is on fire or the fire goes up, these flammable materials are likely to be directly ignited.
Third, the kitchen is equipped with a fire extinguisher. Once the fire, timely and effective fight the initial fire, you can avoid the expansion of the disaster, but also for the firefighters to fight time, so the kitchen is equipped with a fire extinguisher is a must. It is worth noting that the spread of fumes pipe fire is very fast, so the kitchen can be equipped with a "backup" near the fire extinguisher just in case.
Four, kitchen fire without leaving people. Smoke pipe fire, the cause of the fire is mostly kitchen fire "away from people". The fire department emphasized that all types of catering establishments, especially in the neighborhood of the hotel, should effectively improve the fire safety equipment, training operators to master fire safety knowledge, the development of the kitchen fire and electricity management system to ensure that the kitchen fire does not leave the person.
