Research on energy-saving and emission reduction technology for steam boilers in printing and dyeing enterprises
Steam boilers have been applied in various industries,but has problems such as high resource waste rate and serious emissions pollution.To address this problem,an energy-saving and emission reduction scheme based on phosphorus free water treatment technology was proposed and applied to the energy-saving and emission reduction of steam boilers in printing and dyeing enterprises.Simulation experiments were conducted on phosphorus free water treat-ment technology.The results showed that the compliance rate of various indicators in the discharge of wastewater treated with this technology was 100%,the phosphorus mass concentration was reduced to 0.000 1 mg/L,and the mass concentra-tions of mercury and acute toxicity of wastewater were reduced to 0 mg/L.The effectiveness of energy-saving and emission reduction scheme using this technology in the printing and dyeing industry was further analyzed.The results showed that af-ter using this scheme,the natural gas consumption,sewage discharge,boiler water preparation cost,and phosphate dosage of the steam boiler were significantly reduced every quarter.The energy-saving and emission reduction scheme based on phosphorus free water treatment technology can reduce the energy consumption of steam boilers,decrease sewage dis-charge,and reduce the usage costs.
