The invention discloses a ventilation and purification circulating device capable of effectively reducing pollutants, and belongs to the field of
air purification. The ventilation and purification circulating device capable of effectively reducing pollutants. The ventilation and purification circulating device comprises an air inlet pipeline, a dust removal channel, a
microorganism filtering
system, a secondary filtering module, an air sampling head, a negative
ion detection and supplement
system, an air outlet pipeline and the like, and is arranged at a
fresh air inlet of an air conditioningunit according to the characteristics that an
air conditioning system is large in ventilation quantity and high in
fresh air dust content. According to the device, an air
pipe type electronic dust removal technology is used for removing dust, a
biofilm culturing technology is used for eliminating
bacteria to the maximum extent, multiple
layers of filter screens in the secondary filtering system are used for filtering
fresh air in a multiple mode, the air sampling head is used for sampling and warning the content of accumulated dust in an air
pipe, and the negative
ion chamber technology is used for carrying out concentration detection and automatic supplement on the negative
ion content in the filtered air, so that the removal rate of small and medium-sized particulate matter in the air isguaranteed, and the air quality and the
human body comfort are effectively improved.
