Shijiazhuang Zhengyuan chemical fertilizer Co., Ltd
From October 25, 2015 to January 20, 2016, Mingsheng project department entered the construction site and successfully started the system at one time, which lasted for 88 days. Bad weather conditions such as rain and snow brought bad conditions to the construction. At present, the whole system has been accepted by the local environmental protection department. The desulfurization system runs well and stably, the export emission index reaches the national ultra-low emission standard, and the output effect of ammonium sulfate is fully affirmed by the owner. Mingsheng people once again proved their construction ability with facts, and once again created an industry miracle!
two thousand and sixteen On May 27, 2006, 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 academician Hao Jiming of Tsinghua University and other experts, after field inspection of desulfurization industrial device, review of relevant data, 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 achieve sulfur dioxide and smoke dust By reasonably setting the liquid level of the oxidation section, selecting the appropriate pH value and adopting the distributed oxidation method, the efficient oxidation of ammonium sulfite is realized; at the same time, the secondary ammonia and ammonium salt washing and demisting device are developed, which 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 。
