Instructions for the use of smoke exhaust hood in hotels: The smoke exhaust hood of fans generally used in hotels will take away a lot of air from the hotel. When the air make-up fan of lampblack hood is used to extract lampblack, it needs to supplement air to the hotel, which provides about 80% of the air volume of lampblack exhaust. Fresh air pre-treatment fan in the working area - provides the hotel working area (staff working position) with pretreated fresh air.
This machine provides a lampblack exhaust fan that accounts for about 20% of the lampblack exhaust air volume - to exhaust the oil and gas from the lampblack hood in the cooking area. Air leakage prevention measures shall be taken at the connection of each air duct. In order to ensure the infectious effect of the equipment, the variable diameter air duct adjacent to the equipment inlet and outlet shall be as smooth as possible. In order to ensure the infectious effect of the equipment, straight pipes with a length more than 4 times the pipe diameter must be assembled and connected with smooth pipes. Therefore, flexible connection must be used when connecting the air pipes of the equipment's light fans. The equipment will not work normally if it is subject to vibration during operation.
Kitchen lampblack in catering industry mainly floats in the air in the form of aerosol, which is one of the important sources of inhalable particulate matter pollution in urban atmosphere. Jinan smoke exhaust pipe will cause great harm to the atmospheric environment and human health.
Jinan kitchen smoke provides a legal basis for lampblack control, which effectively controls the lampblack pollution of urban Chinese food and beverage industry. However, in practice, there are still a considerable number of lampblack purifiers that have not achieved the expected effect due to unreasonable design or poor management and low purification efficiency.
Explosion proof lamps and UV lamps can often be wiped clean with a wet rag. Those containing water baffle, water fan, oil screen, filter screen and other front-end purification components are the same as those of the smoke exhaust hood panel. Jinan smoke exhaust pipes need to shovel the oil dirt on the surface first, and then soak in caustic water. After the oil sludge is completely soaked, they can be cleaned with a high-pressure water gun (clean water). According to experience, about 80% of kitchens have poor smoke exhaust, which is mainly caused by the dirty and blocked filter screen inside the oil smoke purifier. Therefore, it is very important to clean the components of the front-end purifier.
Each kitchen has a flue, and the flue can be divided into main flue and auxiliary flue. The main flue runs through the whole building, while the auxiliary flue is relatively independent. Generally, the lampblack in the home will go to the auxiliary flue first, and then enter the main flue through the hole on the partition board, so as to ensure that the lampblack in each household is isolated. If the auxiliary flue is directly connected to the main flue, the pressure will be too low, which will lead to the phenomenon of back smoke or smoke.
Jinan smoke exhaust hood focuses on the production and processing of kitchen smoke exhaust hood and other products. For more highlights, please click here: http://www.jnqsg.com , we will have more wonderful content for you to check
