The invention relates to the field of explosion-proof diesel engine emission environmental protection, in particular to a novel mining intelligent controllable waste gas circulation device and a control method. An inlet of a heat preservation type waste gas temperature regulator is connected with an outlet of an explosion-proof electric control diesel engine; a temperature sensor and a pressure sensor are installed in the heat preservation type waste gas temperature regulator; the heat preservation type waste gas temperature regulator is connected with inlets of three sets of waste gas circulation intelligent follow-up multi-way control devices through a heat preservation pipe I, a heat preservation pipe II and a heat preservation pipe III; the three sets of waste gas circulation intelligent follow-up multi-way control devices are communicated with an inlet of a water-cooled multi-pipeline temperature control device through high-temperature rubber pipes; an outlet of the water-cooled multi-pipeline temperature control device is communicated with an explosion-proof proportional electromagnetic valve; a waste gas outlet of the explosion-proof proportional electromagnetic valve is connected with the explosion-proof electric control diesel engine; and an explosion-proof host is connected with the explosion-proof electric control diesel engine, the temperature sensor, the pressure sensor, the waste gas circulation intelligent follow-up multi-way control devices and the explosion-proof proportional electromagnetic valve through electrical circuits.
Description
technical field [0001] The invention relates to the field of explosion-proof diesel engine emission and environmental protection, in particular to a novel mine-used intelligent and controllable exhaust gas circulation device and a control method. Background technique [0002] Mine explosion-proof vehicles have become the main equipment for trackless auxiliary transportation in coal mines. At present, the main power source of mine explosion-proof vehicles is mine explosion-proof diesel engine. With the increasing application of mine explosion-proof diesel engines in coal mine explosion-proof vehicles, the current emission requirements of explosion-proof diesel engines are the same as those of construction machinery diesel engines, but the emission The technology seriously lags behind diesel engines for construction machinery and road diesel engines, and these technologies need to meet explosion-proof requirements when they are applied underground in coal mines. Emissions are...
