If I open a small restaurant, can the kitchen exhaust smoke be discharged into the underground pipe?

The kitchen of the small dining room should not be used to exhaust smoke from underground pipes.

1. According to Article 81 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution, catering service operators who emit fumes shall install fume purification facilities and maintain normal use, or take other fume purification measures to make the fume discharge up to the standard and prevent pollution to the normal living environment of nearby residents;

2. It is forbidden to build, reconstruct or expand catering service projects that produce oily smoke, peculiar smell and exhaust gas in residential buildings, commercial and residential complexes that are not equipped with special flues, and commercial and residential floors adjacent to residential floors, and no unit or individual shall provide a venue for open-air barbecue food in the area prohibited by the local people's government;

3. According to Article 80 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution: Enterprises, public institutions and other producers and operators that produce odorous gases in their production and business activities shall scientifically select sites, set reasonable protective distances, and install purification devices or take other measures to prevent the discharge of odorous gases;

4. According to Article 79 of the Law of the People's Republic of China on the Prevention and Control of Air Pollution, enterprises, public institutions, and other producers and operators who discharge persistent organic pollutants into the atmosphere, as well as the operating units of waste incineration facilities, shall, in accordance with the relevant provisions of the state, adopt technical methods and processes conducive to reducing the discharge of persistent organic pollutants, and equip them with effective purification devices to achieve the discharge standards.

It is not recommended to discharge to the underground pipeline, because the specific gravity of oil smoke is lighter than that of air, and the selectivity of the smoke exhaust fan is forced to be discharged to the underground pipeline, so that the noise is also large; In addition, the underground pipe can not meet your kitchen smoke exhaust requirements, the smoke exhaust effect is not good, once it rains or the underground pipe is blocked for a long time, it can not ......be discharged at all(1590) I know a friend who has more than ten years of experience in smoke exhaust design and installation (587) and is professionally engaged in this.

No, when the air pressure is low on a rainy day, this will cause the smoke to go backwards...In other words, the smoke will be reversed, and the smoke will go up and down the sewer, and the gas will often not pass normally, and if the gas does not melt, then the exhaust smoke will collect at the sewer mouth....

No, the EIA and Environmental Protection Bureau clearly stipulate that catering enterprises must have legal and qualified smoke exhaust pipes, and smoke exhaust pipes are prohibited from being discharged through sewers.

After you open your restaurant, the Environmental Protection Bureau will measure the smoke exhaust in the smoke exhaust pipe to see if it meets the standard, so basically your idea can be dispelled.

If you have a way, it may be a different story.

No, some sewers have problems with the exhaust system, which can lead to the accumulation of large amounts of biogas. If the fumes are discharged into the sewer at this time, an explosion may occur.
