VENTILATION SYSTEM OF WELDING AREA OF INDUSTRIAL ENTERPRISE Russian patent published in 2014 - IPC F24F7/00 

FIELD: ventilation.

SUBSTANCE: exhaust ventilation of the welding area of the industrial enterprise, comprising air-ducts, an exhaust hood, an exhaust fan, an automatic control device, a temperature sensor, and a sensor of concentration of harmful substances. It also comprises a photosensor; all sensors are mounted near the area of welding operations on the exhaust hood; the algorithm of the system operation is based on registration of the light emission with the appearance of the electric arc during welding operations and the exhaust fan turning on for a certain period of time, which enables to accelerate removal of harmful substances from the working area due to faster turning on the exhaust ventilation; hereinafter the microclimate parameters are maintained by the sensor of concentration of harmful substances and the temperature sensor.

EFFECT: improvement of microclimate of the working area during welding operations due to accelerated removal of harmful substances from the working area.
