The invention relates to the field of air pollutant removing devices, in particular to a haze pollutant removing device which comprises a ventilation system with a fan, an air filter device, purification devices and silencers. The ventilation system with the fan comprises a rainproof haze air inlet, an air pressure equalizing chamber, the fan and an air cleaning static pressure tank type spherical jet air outlet; the air filter device comprises a primary filter, an intermediate filter and a high-efficiency filter; the purification devices include one or a plurality of devices including an alkaline aqueous solution spray washing device, an activated carbon adsorption device, a negative ion purification device, a catalytic combustion purification device, an electrostatic dust collection device, an ultraviolet disinfection device, a photonic hydrogen ion purification device, a biological purification device and a three-way catalytic purification device; the silencers include one or a plurality of devices including a silencer at an induce draft end of the fan, a vibration damping muffler device and a silencer at an exhaust end. The haze pollutant removing device has the advantages that clean air can be exhausted to the atmosphere under the filter effects of filters and purification treatment effects of the various purification devices, and accordingly the purpose of quickly removing haze pollutants can be achieved.
