Vehicle tail gas waste heat recovery and corona purification zero-energy-consumption device

The invention discloses a vehicle tail gas waste heat recovery and a corona purification zero-energy-consumption device. A corona generator is arranged in a shell, a thermoelectric power generation piece and a heat dissipation module are arranged outside the shell, the shell transmits heat to the hot end of the thermoelectric power generation piece, and the heat dissipation module achieves low-temperature control over the cold end of the thermoelectric power generation piece and keeps the power generation temperature difference; and the power generation voltage drives the corona generator to work, so that harmful gas is subjected to chemical and ionization electrolytic reaction to further release heat, tail gas purification and reaction heat cyclic utilization are realized, mutual positive feedback of heat-electricity and electricity-heat conversion is achieved, and waste heat recovery and tail gas purification are organically integrated. 本发明公开了一种车辆尾气余热回收与电晕净化零能耗装置，在壳体内设置电晕发生器，在壳体外设置温差发电片和散热模块，壳体将热量传递给温差发电片热端
