Abstract
Description
Technical Field
[0001] The utility model relates to the field of ventilation devices, in particular to a ventilation device for rail transit subway construction. Background Art
[0002] Ventilation systems for rail transit subway construction are key equipment for ensuring air quality, temperature regulation, and fire safety within the subway system. The subway is a relatively closed space with a dense population. Ventilation systems continuously provide fresh air to the subway while simultaneously expelling carbon dioxide exhaled by passengers, human odor, and other pollutants. Through the operation of the ventilator and the guidance of the air duct system, multiple air exchanges can be achieved every hour, ensuring that the air quality inside the subway meets national standards and providing a healthy and comfortable breathing environment for passengers and staff. Current ventilation systems for rail transit subway construction often use a single ventilator for ventilation, but this is inconvenient for filtering odors in the air. Therefore, a ventilation system for rail transit subway construction is needed.
[0003] Existing ventilation systems used in rail transit and subway construction are inconvenient to filter out odors in the air, resulting in unpleasant odors filling the station. Passengers experience discomfort in such an environment, and may even experience physiological reactions such as nausea and dizziness. Furthermore, it is inconvenient to regularly remove and replace the internal filter element. Therefore, a ventilation system for rail transit and subway construction is urgently needed.
