Research Progress of Heat Energy Recycling for Thermal Phosphoric Acid Production
摘要
Abstract
Thermal phosphoric acid process is the cornerstone of China's phosphorus chemical industry based on thermal method.The production energy consumption of the process is analyzed at three levels:production of yellow phosphorus from reduced phosphorus ore,oxidative combus-tion of yellow phosphorus and hydration of phosphorus pentoxide.For the reduction process,the progress and effectiveness of the current energy saving and consumption reduction initiatives in the section are introduced from the three perspectives of raw material taste enhancement,yellow phosphorus slag and tail gas heat recycling,respectively.At the same time,it focuses on reviewing the current status of domestic research on the recycling of yellow phosphorus combustion heat and reaction heat in the hydration process of phosphorus pentoxide,and summarizes the problems of low utilization rate of hydration heat and terminal tail gas heat,and insufficient technology of total heat recycling in this section of the process at present.On this basis,the summary points out that optimizing each link of thermal phosphoric acid production,adopting symbiotic coupling and synergistic development of thermal phosphoric acid and wet phosphoric acid,and exploring a technical route of full thermal energy recycling of oxidative hydration from the perspective of the whole system are of great significance for realizing high efficiency and energy saving and reduction of consumption of the thermal basic phosphorus chemical industry.关键词
