With the acceleration of industrialization process, diesel engine as an important power equipment, has been widely used in various fields, diesel exhaust emissions of pollutants to the environment and human health posed a serious threat, therefore, the laboratory diesel exhaust comprehensive treatment technology research and application is particularly important.
Diesel exhaust mainly contains carbon monoxide, hydrocarbons, nitrogen oxides NOx and particulate matter PM, which are potential hazards to the environment and human health. SCR denitrification technology is one of the most widely used diesel exhaust aftertreatment technologies. Under a certain temperature and catalyst, NH₃ reforms NOx into N₂ and H₂ ₃. Due to high selectivity, NH₃ preferreforms NOx and does not react with O₂ first. In order to avoid secondary pollution caused by NH₃, excess NH₃ should be coated with ammonia escape catalyst ASC at the end of the SCR carrier to ensure that NH₃ reacts with O₂ to form N₂ or H₂O.
Diesel particle catcher DPF captures particulate matter in exhaust gas by physical means, which can effectively reduce PM emissions. DPF needs to be regenerated regularly to maintain its capture efficiency. In the laboratory of a scientific research institution, through local ventilation and exhaust gas collection, activated carbon adsorption technology and exhaust gas monitoring and emission steps, effectively control exhaust gas emissions, to protect the laboratory environment and personnel health.
Environmental protection and human health are vital. Through the use of SCR, DPF, RGR, low temperature plasma technology and catalytic purification technology and other comprehensive treatment measures, can effectively reduce the emissions of pollutants in diesel exhaust, to achieve the sustainable development of the environment, with the continuous progress and innovation of technology, the future laboratory diesel engine treatment technology will be more environmentally friendly and efficient.
