If the hot pot restaurant is adjacent to a tall chimney, there are the following solutions:

1. Install efficient chimney purification equipment: You can install efficient purification equipment on the chimney of the hot pot restaurant, such as smoke filter or soot settling equipment, to reduce the pollutants emitted by the chimney. This can reduce the impact of smoke and oil fume generated in the store on the surrounding environment.

2. Increase the chimney height: If the chimney height is not enough, consider increasing the chimney height to exceed the height of surrounding high-rise buildings. In this way, the smoke and oil fume emitted by the chimney of the hot pot restaurant will be more easily dispersed into the surrounding air, reducing the impact on neighboring buildings and residents.

3. Consultation with the property and residents: Hot pot restaurants can communicate and negotiate with the property and residents of surrounding high-rise buildings to discuss how to reduce the impact of smoke and oil fume on the surrounding environment. You can seek the same solution, for example, you can invest in building efficient purification equipment or improving chimney design.

4. Clean the chimney and exhaust equipment in time: clean and maintain the chimney and exhaust equipment regularly to ensure their normal operation. This can effectively reduce the emission of smoke and lampblack.

it should be noted that the specific solutions need to be determined according to local laws and regulations and environmental protection requirements. If none of the above solutions can effectively solve the problem, it is recommended to consult relevant departments or professionals to seek more professional opinions and solutions.
