Fresh air ventilator with dust removal and intelligent humidity control functions

The invention relates to a fresh air ventilator with dust removal and intelligent humidity control functions. The dust containing fresh air enters a fresh air passage from a fresh air inlet, is filtered, humidified or dehumidified by a wet type filter section and is subjected to energy recovering by a cross-flow type fresh exhaust air heat exchanger and indoor exhaust air, and the clean air meeting the humidity requirement is sent into a room by a blower. An automatic rotary high-pressure spray head of the wet type filter section continuously sprays and filters dust in the fresh air. An indoorrelative humidity sensor measures the relative humidity of the indoor air, transmits the data to a control module, and then the heating quantity of a pipeline type electric heater is adjusted and controlled to adjust the water feeding temperature of the wet type filter section to realize the humidification or dehumidification of the fresh air. According to the fresh air ventilator with the dust removal and intelligent hu
