Mingsheng environmental protection and Zhongyuan Dahua Co., Ltd. This ammonia desulfurization cooperation project is applicable to the flue gas ammonia desulfurization and ammonium sulfate device of the methanol division of Henan Zhongyuan Dahua Group Co., Ltd. and the No. 1, 2 and 3 boiler flue gas desulfurization and ammonium sulfate device of the chemical fertilizer business department. The flue gas treatment is set according to the configuration of three boilers and one tower, and the flue gas treatment capacity of methanol division is designed according to the total flue gas volume of three boilers with a total of 1050000m3 / h The chemical fertilizer division is designed according to the flue gas volume of 780000m3 / h with three boilers fully opened. The SO2 emission index at the outlet of desulfurization tower is less than 35mg / Nm3 (standard state, dry basis, 6% oxygen), and the emission index of total dust (including soluble dust) is less than 5mg / Nm3 (standard state, dry basis, 6% oxygen). When the dust content in flue gas at the inlet of desulfurization tower is not more than 30mg / Nm3, the quality of ammonium sulfate can reach the GB535-1995 qualified product standard.
Through the painstaking work of Mingsheng "craftsman", a fine project of ammonia desulfurization has been established in the Central Plains!
