Multiscale Simulation of Phosphoric Acid Productionby Thermal Process
From the perspective of combustion thermodynamics,reaction-mass transfer mechanism and the whole process synthesis,the influence of technological and structural parameters on the combustion characteristics of the phosphorus tower was analyzed,and the"three transfer and one reverse"mechanism of yellow phosphorus combustion was explored.The results show that if the air excess coefficient is lower,the center temperature of the phosphorus burning tower will be higher,and if it is higher,the energy will be wasted,so the middle value is 1.5.The increase of the spray gun Angle can improve the preheating recovery rate,but it will affect the temperature distribution of the tower body.Therefore,when the spray gun Angle is 41°,the maximum temperature in the tower will decrease and the combustion area will increase when the number of spray guns is 3,which is better than the tower type with two spray guns,but the cost will increase.This study optimizes the heat recovery efficiency of phosphorus-burning furnace,which can provide a reliable reference for the optimization scheme of phosphoric acid by thermal process in the factory.
