Zusammenfassung:The invention provides a cement production tail exhaust flue gas purification system and a process method. The cement production tail exhaust flue gas purification system comprises an oxidation module, a circulating purification module, a byproduct extraction module, a pit module, a process water washing module and an absorbent balance module. The oxidation module is used for conveying oxygen into the purification tower to carry out oxidation reaction, the circulation purification module is used for carrying out circulation purification on flue gas through an absorption spraying layer and a water washing spraying layer in the purification tower, and the by-product extraction module is used for filtering and extracting by-products discharged from the purification tower. The pit module is used for overflowing and refluxing a solution in the purification tower, the process water washing module is used for flushing the purification tower, and the absorbent balancing module is used for balancing the concentration
