WELDING FUME AND GAS ELIMINATOR

摘要

A weld-fume removing device for treating concurrently a particulate and gaseous phases is provided to remove both particulate and gaseous weld-fumes, to maximize electric efficiency by utilizing an air-cooled type of heat exchanger in a gas phase removing device, and to prevent the temperature in a workplace from being increased with the welding heat by installing a discharged-air cooling unit, that is, a cooler to cool air in workplace. A weld-fume removing device for treating concurrently a particulate and gaseous phases comprises: a duct(2) connected with a weld-fume suction hood; a fume particle removing unit(3) for eliminating the particulate phase of weld-fumes; a dust removing unit(4) for intermittently eliminating the collected fume particles; an absorbing unit(5) for collecting the gaseous fume; a ring blower(6) sucking the weld-fumes and discharging purified air; a catalytic unit(9) for completely resolving the gaseous fume; a heat exchanger(7) preheating the gaseous fume inflowing to the catalytic unit and cooling the purified air discharged from the catalytic unit; a heater(8) increasing temperature of the gaseous fume passing through the heat exchanger and inflowing to the catalytic unit; and a cooler(10) falling temperature of the purified air discharge from the heat exchanger.
