The invention relates to environment-friendly treatment of emissions of an explosion-proof diesel engine. At present, an explosion-proof diesel engine emission technology in China lags behind seriously, a large amount of nitric oxide NO<X> is contained, and the great harm is generated to body health of underground coal mine operators. The invention provides an explosion-proof diesel engine intelligent control accurate cylinder temperature NO<X> reduction device and method. The gas indexes in the emissions are not deteriorated, reducing NO<X> is the main purpose, the exhaust gas recycling efficiency is calibrated by taking into account hydrocarbon HC, CO, smoke index and the like, the pressure and flow of gas in a multi-fluid cooling device are automatically controlled and adjusted througha sensor detection system and a pneumatic flow control system by an explosion-proof intelligent centralized control system, and accurate control over the pressure, temperature and flow of the gas in the multi-fluid cooling device is achieved; and accurate control over the combustion temperature in a power system cylinder is achieved by controlling the flow of circulating gas, and the emission amount of NO<X> is reduced.
Description
technical field [0001] The invention relates to environmental protection treatment of explosion-proof diesel engine emissions, and more specifically, relates to an explosion-proof diesel engine intelligently controlling precise cylinder temperature to reduce NO X Devices and methods. Background technique [0002] Explosion-proof rubber-tyred vehicles have become the main equipment for trackless auxiliary transportation in coal mines, and explosion-proof diesel engines, as the main power source of explosion-proof rubber-tyred vehicles, are more and more used in underground explosion-proof rubber-tyred vehicles. At present, the emission requirements of domestic explosion-proof diesel engines are much lower than those of construction machinery diesel engines and road diesel engines, and the emission technology seriously lags behind other power equipment. Emissions are very harmful to the health of underground coal mine workers, especially the emissions contain a large amount o...
