Wind speed of welding fume processing equipment on welding shop
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.
The soldering fume purification system is composed of a purifier main body, a fume removing arm, a fume removing cover, a pipe and a bracket, etc., which can realize the functions of extraction, transportation and purification of fume. This system is specially designed for the purification of manual welding fumes. It is divided into KFC series single and double station smoke purification systems and KFF series multi-station smoke purification systems. They all use imported special fans with large air volume and high wind pressure. Low noise and continuous operation;
