Shenyang smoke exhaust project What should we pay attention to in the catering industry?

For the kitchen of the catering industry, whether the smoke exhaust is unobstructed is directly related to whether the kitchen can work normally, and the oil smoke purification is only a mandatory function of the kitchen smoke exhaust system to purify the air.

1. Composition of kitchen smoke exhaust system.

The smoke exhaust system of the kitchen is mainly composed of the smoke collecting hood, smoke exhaust pipe, oil smoke purifier, smoke exhaust fan and the overall air supplement device of the kitchen.

The type and operation mode of the fume purifier can be selected according to the actual situation. Before the installation of the fume purifier, the actual operating parameters of each part of the smoke exhaust system, including the operating resistance and exhaust air volume, should be calculated first.

As the layout of the building where the kitchen is located and the position of the kitchen in the building are different, conditional kitchens should be orderly supplied by the central air-conditioning system of the building.

2. The disordered air supply will cause a bad working environment in the kitchen. Especially in summer, although some local cabinet air conditioners are usually installed in the dining room to reduce the indoor temperature of the dining room, the supplement of indoor air into the kitchen cannot eliminate the heat load of the kitchen and reduce the kitchen temperature. Due to the large oil smoke in the kitchen, if a local cabinet air conditioner is set in the kitchen to reduce the temperature in the kitchen, the return air filtration of the cabinet air conditioner should be cleaned regularly.

For buildings with centralized air conditioning systems, the working environment of the kitchen can ensure that the air supply is mostly orderly and flexible.

The gas collecting hood is generally processed as a whole, including filtration, oil collection, water collection and other equipment, which are mostly made by professional companies. Its appearance should be unified, beautiful and easy to clean. In the kitchen ventilation, a certain amount of fresh air should be added. On the one hand, it can balance the air pressure to avoid excessive negative pressure in the kitchen. On the other hand, it can reduce the temperature in the kitchen and improve the working environment.

3. Smoke exhaust pipe.

The horizontal section of the kitchen smoke exhaust pipe should not be too long, and the horizontal end should be equipped with a movable joint to facilitate the cleaning of oil dirt. The exhaust speed shall not be less than 10m/s according to the specification to prevent the oil from adhering to the flue due to the low wind speed. The branch pipe connected to the exhaust hood shall be equipped with an air volume regulating valve.
