The invention relates to an integral lifting hot phosphoric acid afterheat utilization device. The device comprises a steam pocket, a steam guide pipe, a descending pipe, an upper seal, a combustion radiation heat exchange evaporator, a phosphorus spraying combustion gun, a lower seal, an elastic lifting hook and a bracket. The combustion radiation heat exchange evaporator is provided with upper,middle and lower annular headers; a vertical annular film water cooling wall is arranged between the upper header and the middle header; a conical film water cooling wall is arranged between the middle header and the lower header; a combustion chamber and a radiation heat exchanger chamber are synthesized to form an integral water circulating system; and meanwhile, the combustion radiation heat exchange evaporator is suspended on the bracket by adopting the elastic lifting hook. The conical film water cooling wall structure is adopted to replace a double-jacket lower seal, so that the heat ofthe bottom combustion chamber is totally used; and the whole device adopts a lifting mode, is integrally operated to expand buffer space of equipment, and is simple in structure, low in weight, high in heat recovery efficiency and safe and reliable in operation.
Description
technical field [0001] The invention relates to the technical field of chemical equipment, in particular to an integrated hoisting type thermal phosphoric acid waste heat utilization device. Background technique [0002] Phosphoric acid is an important chemical raw material and intermediate, which can be used to manufacture phosphate fertilizers and various phosphates. Thermal phosphoric acid can obtain phosphoric acid with high concentration and high purity. The purified high-purity phosphoric acid can be used in food, medical, electronics, Biology and other industries. [0003] In thermal production, the phosphate rock is first smelted in an electric furnace to obtain elemental phosphorus, and then the elemental phosphorus is atomized and burned with air in a combustion tower to generate P 4 o 10 The gas is then hydrated to obtain thermal phosphoric acid. The process of thermal phosphoric acid includes one-step combustion hydration process and two-step combustion hydrat...
