The invention relates to environmental protection treatment of explosion-proof diesel engine emissions; the current domestic explosion-proof diesel engine emission technology is seriously lagging behind, containing a large amount of nitrogen oxides NO X , which is very harmful to the health of coal mine workers, the invention provides an explosion-proof diesel engine with intelligent control of precise cylinder temperature to reduce NO X Device and method to ensure that the gas indicators in the emissions do not deteriorate, so as to reduce NO X As the main purpose, the exhaust gas recycling rate is calibrated taking into account indicators such as hydrocarbons HC, CO and smoke. The explosion-proof intelligent centralized control system uses the sensor detection system and the pneumatic flow control system to automatically control and adjust the pressure and flow of the gas in the multi-fluid cooling device. , the pressure, temperature and flow of the gas in the multi-fluid cooling device can be precisely controlled, and the combustion temperature in the cylinder of the power system can be precisely controlled by controlling the flow of the circulating gas to reduce NO X emissions.
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...
