A, kitchen flue cleaning
1, disassembly method
This method is the most thorough, the cleaning effect is the best way, but the construction is difficult, the number of workers is also more, at the same time the cost is also relatively high. Cleaning program is: technicians in accordance with the actual situation of the pipeline, measured every certain distance to dismantle a section of the pipeline and extend the cleaning in both directions to ensure that the quality of cleanup by the construction team leader to check the cleanliness of the oil-free allow installation.
2, open hole method
This method is relatively easier than the demolition method, the cost is relatively low, but the cleaning effect is also relatively have a certain gap. Specific method is: by the technicians measured the distance between the need to open the hole, the hole location, size and number of holes, through the opening of holes in the pipe for cleaning; and finally sealing treatment for each hole.
3, mechanical equipment method
This method is the easiest to operate, the minimum difficulty and workload, the lowest cost, but the cleaning effect is also the worst, but for the cleaning cycle of half a year or less of the vertical pipeline, this cleaning method is undoubtedly the best choice. Specific method is: in the vertical pipe at the upper end of the inward spraying of chemical grease oil stains automatically slide down until the horizontal pipeline, the construction workers operating process at the same time clean up.
Two, kitchen cleaning notes
1, some of the old fume extraction equipment fume hood aging, resulting in fume hood leakage, smoke emissions drop; fume exhaust fan aging resulting in a decline in the speed of rotation, the decline in the amount of smoke emissions, the old fume extraction equipment, fume pipe are relatively thin, due to the long time the accumulation of grease and dirt and inconvenient to clean, but also the same cause The effect of smoke exhaust is not good.
2, hood in the use of a period of time, hood impeller, flue will be stuck with a lot of oil, which increases the weight of the impeller, so it is bound to increase the rolling kinetic energy of the wind turbine, at the same time to make the motor starting current increase.
3, a long time without cleaning the hood, the current is 3-6 times the normal value of the power on, so it is easy to burn the motor, so regularly clean the hood, the motor is an excellent maintenance effect, can extend the life of the hood.
4, oil sticking to the motor shaft, increasing the friction, so that the motor load increased - electricity. Oil pollution for a long time accumulation, oxidation occurs to constitute acidic substances, the hood corrosion, rust, accelerate the hood aging.
5, oil pollution long time accumulation in the hood inside and inside the flue, will also constitute a fire hazard. Impeller, flue oil on the increased viscosity, so that the exhaust is not unclogged, increasing the dispersion of fumes on the kitchen space, damage to everyone's health.
