At present, the energy utilization efficiency of automobile engines is generally low. Only about 1/3 of the chemical energy released by engine fuel is effectively used. Most of the energy is lost or discharged into the atmosphere in the form of waste heat, which causes a great waste of energy. Based on the above problems, this work proposes a device for the purification of automobile exhaust gas and the efficient use of automobile residual energy. This design effectively increases the contact area of the harmful gas and the catalyst and improves the catalytic efficiency. At the same time, a thermoelectric power generation system is arranged in the electrostatic precipitator room, which converts the heat energy of automobile engine exhaust into electrical energy, and realizes energy recovery and utilization. The device of the invention realizes the recycling of the exhaust energy of the engine exhaust, effectively solves the defects existing in the traditional three-way catalyst, and reduces the pollution and harm caused by the exhaust gas.
