A mine-used intelligent controllable waste gas circulation device and control method

Abstract

The invention relates to the field of environmental protection of explosion-proof diesel engine emissions, in particular to a novel mining intelligent controllable exhaust gas circulation device and a control method. The inlet of the thermal insulation type exhaust gas temperature regulator is connected to the outlet of the explosion-proof electronically controlled diesel engine. The temperature sensor and the pressure sensor are installed in the thermal insulation type exhaust gas temperature regulator. The thermal insulation type exhaust gas temperature regulator passes through insulation pipe I, insulation pipe II and insulation pipe III respectively. It is connected with the inlets of the three groups of intelligent follow-up multi-channel control devices for exhaust gas circulation. The outlet of the device is connected to the explosion-proof proportional solenoid valve, and the exhaust gas outlet of the explosion-proof proportional solenoid valve is connected to the explosion-proof electronically controlled diesel engine; the explosion-proof host is respectively connected to the explosion-proof electronically controlled diesel engine, temperature sensor, pressure sensor, and exhaust gas circulation through the electrical circuit. Intelligent follow-up multi-channel control The device is connected to the explosion-proof proportional solenoid valve.

Description

technical field [0001] The invention relates to the field of explosion-proof diesel engine emission and environmental protection, in particular to an intelligent and controllable exhaust gas circulation device for mining 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 ver...
