The invention discloses smog emission equipment capable of purifying electronic welding fume. The smog emission equipment is characterized by comprising a support (1), a suction fan (2), a purification tank (3), an exhaust fan (5), an air suction device and a controller (10), wherein the suction fan (2), the purification tank (3) and the exhaust fan (5) are all arranged on the support (1); the airsuction device is connected with the suction fan (2); the controller (10) is separately connected with the suction fan (2) and the exhaust fan (5). The smog emission equipment disclosed by the invention has the advantages of simple structure and strong practicability; as the air suction device and the suction fan are matched, the equipment can effectively suck fume generated by electronic welding; meanwhile, the purification tank is arranged to filter a rosin component in the electronic welding fume, and the electronic welding fume can be cleaner and can be exhausted from the exhaust fan; thus, the equipment can well solve the problem that existing electronic welding fume equipment cannot perform purification treatment on the fume, and harm caused by the welding fume to the human body iseffectively avoided.
