Welding fume treatment avoids heat loss in the workshop
The principle of layered air supply is different from the traditional welding fume treatment equipment . In fact, the layered air supply technology can be used to treat welding fume. Is this really possible? Let's take a look below:
If there is a workshop with a heat source, we have a stable temperature gradient in height, then at a lower wind speed, if it is a larger air volume, the fresh air temperature will be smaller (Δt = 2 ~ 4 ℃) Directly into the indoor work area. In this case, the low-temperature fresh air first sinks under the effect of gravity, and then slowly diffuses, 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.
When the welding smoke treatment equipment reaches stability, the indoor air will form two areas in temperature and concentration The fresh air heater is installed in the processing equipment, so that the fresh air sent to the workshop will not affect the workshop temperature because the temperature is too low. In this way, direct discharge of pollutants to avoid thermal energy loss in the workshop is avoided.
