AI Technical Summary
The existing underground ventilation system has low efficiency in condensate treatment, which can easily interact with the air in the ventilation duct and cause secondary air pollution. Furthermore, the condensate drainage relies on manual or natural infiltration, which is difficult to do in a timely manner and is prone to bacterial growth.
A duct condensate collection and drainage system was designed, comprising a separate collection well and a drainage module. An automatic drainage pump is controlled by a liquid level sensor. Combined with a duct with an inclination of 0.7%-1% and a three-layer staggered arrangement, an antibacterial coating and a temperature and humidity detection module are used to achieve effective collection and drainage of condensate.
This effectively separates condensate from ventilation ducts, preventing secondary air pollution, ensuring timely drainage of condensate, reducing bacterial growth, improving system operating efficiency and air quality, and lowering maintenance costs.
