When building a house, the kitchen is like this. It must be designed with a kitchen to exhaust the smoke. Otherwise, it is usually impossible to exhaust the smoke in the later stage, which will not only cause air pollution in the home, but also harm the health. But many people don't understand the design of kitchen exhaust, so it can't be designed normally. So, next, let's take a look at the principle and design points of kitchen exhaust system. In addition, in daily use, the kitchen exhaust pipe must be cleaned to ensure normal use.
Jinan kitchen smoke exhaust system is mainly composed of smoke collection hood, smoke exhaust pipe, fume purifier, smoke exhaust fan (including muffler), kitchen air supply device, etc.
Because the layout of the building where the kitchen is located is different from the orientation of the kitchen in the building, the conditional kitchen should be orderly ventilated by the air conditioning system connected to the building. But in most cases, the building does not have a kitchen air supply. Many buildings with restaurants, kitchens, etc. have only one combined heating system, but not one combined air conditioning system. When the kitchen is in operation state, put the exhaust system into operation, and the kitchen is in negative pressure state. The fresh air source includes outdoor fresh air infiltration and a large number of restaurant air entering the kitchen.
Many people know there is a flue, but they don't know there is a secondary flue. The main flue runs through the whole building, while the auxiliary flue is independent. There is a partition wall with holes between it and the main flue, and the upper and lower layers are sealed. And the oil smoke in the home is first to the secondary flue and then to the secondary flue. The secondary flue has a buffering effect. The oil smoke enters the main flue through the hole on the partition plate, so as to ensure that the oil smoke is not separated and avoid smoke.
