摘要： The present invention discloses an automatic source-seeking indoor pollution purifying and removing device and method for airborne pollutants. The device comprises pollutant concentration sensors, a control unit, a position sensor, a power plant, a moving mechanism, a telescopic device, a pollutant collection hood, and a filtering and purifying device. The control unit can identify the actual release positions and hourly release rates of relevant pollutants according to the concentration data monitored by the pollutant concentration sensors, and can control the pollutant collection hood in the device to move to a designated position in a space, so as to realize the collection and removal of pollutants at the release position of the pollutants.

摘要： The present invention discloses a ventilator with dual flow passages. There is a mode switcher on the partition board. The ventilator has a variety of operating modes, such as, the natural or mechanical driving mode according to outdoor wind speed, and single-effect or multi-effect filtration according to the outdoor air pollution conditions. The single-effect filtration uses only the primary-efficiency filter, while the three-effect filtration uses the primary-, medium-, and high-efficiency filters. The mode switcher on the partition board can open or close the by-pass baffle to bypass or go through the medium- and high-efficiency filters for switching between the single-effect and multi-effect filtration. In case some indoor pollution sources need to be removed quickly, the recirculated indoor air filtration can be run. In such situation, the primary-efficiency filter in the mechanically-driven flow passage is bypassed, while the fan drives indoor air passing the medium- and high-efficiency filters.
