Description

technical field [0001] The invention relates to a comprehensive balance utilization system of yellow phosphorus tail gas waste heat by an electric furnace method, in particular to a yellow phosphorus tail gas waste heat power generation and heat balance system used in the production of yellow phosphorus by an electric furnace method. Background technique [0002] When producing yellow phosphorus by the electric furnace method, phosphate rock, silica, and coke are mixed according to the proportion of ingredients. In the electric furnace, the phosphorus element in the phosphate rock is reduced to simple phosphorus, and the coke is oxidized to carbon monoxide during the reaction process. The carbon monoxide produced by the reaction escapes from the electric furnace together with gaseous elemental phosphorus, ash and a small amount of water vapor, and is washed and cooled by spray water in a three-stage spray cooling tower, so that the gaseous elemental phosphorus is condensed in...
