Gravity effect of welding fume processing equipment in welding workshop
In the welding workshop, the welding smoke processing equipment has a stable temperature gradient in height. If the wind speed is low, fresh air with a small difference in supply air temperature is directly sent to the indoor work area. The low-temperature fresh air is first lowered by gravity. Shen, then slowly spread, forming a thin layer of air on the ground. The hot air flow generated by the indoor heat source rises due to the buoyancy and continuously entrains the surrounding air. In this way, the fresh air above the floor slowly moves upward due to the entrainment effect of the rising hot air flow, the subsequent fresh air boosting effect and the suction effect of the lion song high-pressure fan, so that the flow is similar to an upward uniform flow, so the work area The foul air is replaced by subsequent fresh air.
Due to the gravity of the fan, the welding smoke exhaust gas is sucked into the air inlet of the equipment through the universal dust hood. The flame arrester is installed at the air inlet of the welding smoke treatment equipment . The spark is blocked by the flame arrester, and the smoke gas enters the sedimentation chamber. First, the coarse dust is directly lowered to the ash hopper. The particulate soot is captured on the outer surface by the filter element. After the clean gas is filtered and purified by the filter element, it flows into the clean room from the center of the filter element, and the clean air is further purified by adsorption by the activated carbon filter. The air outlet meets the standard and is discharged.
