The present invention is a closed condensed water reclaimer, has following advantage:
1. condensed water can directly be supplied with boiler after reclaiming, and boiler feed temperature is improved, and reduces boiler coal consumption significantly;
2. condensed water is a pure water, does not need soft water to handle and just can directly get into the boiler use, thereby practiced thrift a large amount of cost of water treatment;
3. in the condensed water removal process, it is distilled water fully, and the hardness of water quality is very little, can not make boiler produce incrustation scale, and boiler blow-off reduces, and has stablized steam pressure, has reduced the boiler water consumption, and fuel savings has reached desirable energy-saving effect;
4. use because of condensed water reclaims recirculation, thereby reduce quantity of wastewater effluent, practiced thrift cost of sewage disposal;
5. reduce boiler operatiopn time and operating cost, improved boiler duty, saved boiler cleaning expense, water rate and the electricity charge;
6. increase hot biography speed, improve machine efficiency, reduce a pot interior water temperature difference, steam pressure is stable, improves boiler efficiency, the prolonged boiler life-span.
