Description

technical field [0001] The invention belongs to the technical field of industrial waste heat utilization, and in particular relates to a flexible power generation device utilizing industrial waste heat and a manufacturing method. Background technique [0002] Many industrial processes are accompanied by heat generation, such as industrial sewage treatment, ammonia and sulfuric acid manufacturing processes, etc. The essence of these processes are chemical exothermic reactions. The most typical example is that the neutralization exothermic reaction of sulfuric acid and lime water is usually used to produce calcium sulfate precipitation, so as to realize the treatment of acid sewage; the three steps in sulfuric acid production are all exothermic reactions: S+O 2 =SO 2 ;2SO 2 +O 2 =SO 3 ; nSO 3 +H 2 O=H 2 SO 4 +(n-1)SO 3 , and the heat generated by each process is 3310.08KJ / mol, 99KJ / mol, and 132.5KJ / mol respectively. Therefore, the waste heat energy generated by indus...
