Condensed water of boiler treatment process design

Abstract
　　The boiler steam condensation water reuse is a industry for energy conservation and emissions reduction. This article through the condensed water use of good benefit analysis method is introduced , this paper discusses the feasibility of the steam condensation water recycling, necessity and importance.
　　This paper expounds the main industrial boiler water quality indexes, and the boiler water supply and pan of water of the water treatment method and principle are summarized. This design is divided into the pot and the pot water treatment water treatment. The condensed water pot water treatment after into recycling equipment, sodium hydrogen ion exchange chromatography, except the iron processing, oxygen treatment, sewage treatment, and finally the water treatment in the pot. The condensed water boiler water treatment process has been quite mature. The condensed water of boiler treatment production of the raw material technology is already quite mature, and the advantages of this technology are: functional layout area clear, smooth process, the pipeline simple, smooth transportation, the production process proper waste disposal reasonable, production areas are relatively concentrated layout, the workshop is also close to the load center etc. The operation result shows that this system has better economic and environmental benefits due to its advanced technique, simple operation, high recovery and high pollution control efficiency.
　　　The design of water quality stabilization process design include: process design, material balance, process equipment selection, Energy calculations.
Keywords: Boiler condensate water; Recovery ; Energy saving ;Sewage ; Lon exchange .
