Condensate recycling.
Background technique
Condensed water results from steam during heating and conveying, and present many condensed water collecting boxes are open types, with
Atmosphere communicates, and since pressure reduces suddenly when condensed water enters collecting box, water temperature is higher than the corresponding boiling point of the pressure, generates a large amount of
Secondary flash vapour, remaining condensate temperature are about 100 DEG C.In fact, due to flash distillation heat dissipation or sometimes for prevent conveying water
Pump cavitation and be blended into cold water, recycle water temperature only at 70 DEG C or so.In addition Recovery with Open-loop mode has air and enters condensing hot air furnace
Pipeline easily causes corrosive pipeline.But open system device is simple, invests less.But the recycling of condensed water reuses rate with regard to big
It reduces greatly.
Summary of the invention
