This project is a cooperative control technology and applied technology project of ningbo University, located in Meishan Campus of Ningbo University. The Meishan Campus of Ningbo University is jointly built by Ningbo University and Beilun District Government (Management Committee of Meishan Bonded Port Area). The campus has been moved to the School of Marine Affairs, The School of Oceanography and the newly established School of Food and Pharmacy of Ningbo University, and part of the research platform of the Institute of New Drugs of Ningbo University has also settled in the campus. The campus will strive to become an important platform for high-tech r&d of Ningbo International Marine Ecological Science and Technology City/Meishan International Logistics Industry cluster, a major gathering place for high-level talents, an important training base for innovative talents, and an important window for international educational science and technology cooperation.
The project unit is 1100KW Marine diesel engine, and 1 set of C-DPF, 1 set of DOC and 1 set of SCR are set in its export flue for treating PM, HC, CO and NOx in exhaust gas. After c-DPF, DOC and SCR, the exhaust emission performance of the diesel engine should be guaranteed. It is required that the emission concentration of HC+NOx, CO and PM should not be higher than 11g/ KWH, 5.0g/ KWH and 0.27g/ KWH for the final system export.
This project realizes the emission control of most major pollutants of internal combustion engine (except sulfide), and fully demonstrates the professionalism, extensiveness and advancement of internal combustion engine tail gas treatment technology of our company. In addition, on the basis of conventional DPF, the electric heating function was added to realize the regeneration of DPF catalyst, which was also a highlight of the project. During the unit commissioning, our company actively cooperated with the owner to adjust the requirements. After the exhaust gas of the unit went through the whole system of C-DPF, DOC and SCR, the PM, HC, CO and NOx emissions all met the performance indexes and were put into operation successfully.
