KR950014827A - Evaporation & Evaporative Concentration Drying Apparatus and Method with Steam Purification Capability - Google Patents

Abstract

The present invention conserves evaporation energy by using liquefied vaporization heat of steam generated in the process of forced evaporation or pressurized evaporation to recycle latent heat (539kca1 / l in water). Evaporative gases such as B.0.D., C.0.D. and other evaporative gases (water vapor impurities) which are deteriorated and deteriorate the water quality of condensate are removed by oxidative combustion or carbonization at high temperature to significantly clean high quality distilled water. In addition, the high temperature heating energy of steam can be absorbed as steam preheating energy by heat exchange method and reused to produce high temperature steam, thus saving energy, which can be used for distillation water purification treatment of wastewater and concentration and drying treatment of various environmental pollution sludge Evaporation & Evaporation Concentration Drying Apparatus & Method
