Description

Technical Field

[0001] This invention belongs to the field of oil fume treatment technology, specifically referring to an oil fume purification device for residential buildings based on wind speed sensing control. Background Technology

[0002] Most modern high-rise residential buildings are designed with a continuous flue system, where each household connects its range hood to the flue. The cooking fumes are then centrally discharged through exhaust vents located on the roof. This centralized design makes it possible to purify the cooking fumes emitted from high-rise residential buildings before discharging them, greatly reducing environmental pollution. However, the emission of cooking fumes is generally concentrated during cooking time, with very little or no emission at other times. Running the purification equipment all day would undoubtedly increase power consumption and shorten the equipment's lifespan. If it is only turned on during designated time periods, the experience for residents using it at other times would be unpleasant. Therefore, the most reasonable solution is to detect whether cooking fumes are passing through, thereby controlling the opening and closing of the purification equipment. Summary of the Invention

The device uses a vortex booster to transform weak airflow into rapid flow, thereby driving the rotating device. The speed of the impeller is measured by a speed measuring device. When the speed reaches a critical value, the controller drives the purification device to purify the air in the duct. This effectively solves the problem of the difficulty in determining the opening time of centralized fume purification devices in high-rise residential areas currently on the market.
