On May 27, the Chinese society of Environmental Sciences held a meeting in Shijiazhuang, Hebei Province, which was developed by Shandong Mingsheng Chemical Engineering Co., Ltd“ Integrated technology of step separation and purification of ammonia desulfurization and dust removal ”Achievement appraisal meeting.
The appraisal committee composed of Hao Jiming, academician of Tsinghua University and other experts, after on-the-spot investigation of desulfurization industrial device, review of relevant data, and after inquiry and discussion, unanimously agreed that the technology has developed a "dual structure" multi-functional integrated dual cycle desulfurization process and supporting equipment to solve the problems of ammonia desulfurization and dust removal and ammonia escape of coal-fired boiler flue gas The high-efficiency oxidation of ammonium sulfite is realized by reasonably setting the liquid level in the oxidation section, selecting the appropriate pH value and adopting the distributed oxidation method. At the same time, the secondary ammonia and ammonium salt washing and demisting device are developed to effectively control the escape of ammonia and ammonium salt. All agreed to pass the appraisal.
According to the appraisal committee, the process equipment is compact, the floor area is small, the one-time investment is low, there is no secondary pollution, and the by-product ammonium sulfate can be used as resource. The appraisal committee identified that the research results achieved International advanced level 。
