Zusammenfassung:	The invention discloses a comprehensive recycling technology for low-grade steam containing acid non-condensable gas. The comprehensive recycling technology comprises the steps that an organic Rankine cycle low-temperature power generation technology is adopted for recycling heat energy, the acid non-condensable gas in the low-grade steam is recycled for producing 98% sulfuric acid, and low-pressure flash steam condensate is recycled after being purified. According to the comprehensive recycling technology for the low-grade steam containing the acid non-condensable gas, heat energy of the low-grade steam containing pollutants is converted into clean electric energy through an organic Rankine cycle low-temperature power generation technology, and sufficient recycling of heat is achieved; pollutants such as hydrogen sulfide and ammonia in the steam are used for preparing 98% sulfuric acid through a sulfur recovery device, so that waste is turned into wealth; and the condensate is purified and reused, so that th
