Problems solved by technology
Broken ceramics may accumulate in the exhaust bag, causing exhaust obstruction and weak acceleration, and when the engine decelerates rapidly, the broken ceramic powder will be sucked back into the cylinder with the fluctuation of exhaust pressure, causing engine damage. Severe wear and tear, serious even make the engine scrapped
[0012] Based on the above-mentioned defects of the three-way catalytic converter, someone has studied a tail gas treatment device that washes the vehicle tail gas with water and then discharges the washed tail gas. exhaust gas treatment standard

The invention discloses a tail gas treatment device. The tail gas treatment device comprises a cavity, an electro-adsorption part and an electro-oxidation part. The electro-adsorption part is arranged in the cavity and comprises a plurality of first electrodes, at least one of the first electrodes is electrically connected to an anode of a power source, and at least another one of the first electrodes is electrically connected to a cathode of the power source. The electro-oxidation part is arranged in the cavity and comprises conducting liquid and a plurality of second electrodes, the second electrodes are partially electrically connected to the anode of the power source, the other second electrodes are electrically connected to the cathode of the power source, and the second electrodes are electrically connected through the conducting liquid. By application of the tail gas treatment device, various pollutants in tail gas can be thoroughly removed through electrostatic precipitation and electrochemical oxidation, and various problems in use of an existing three-way catalytic converter can be avoided. In addition, the tail gas treatment device has advantages of energy saving and environment friendliness.
Description
technical field [0001] The invention relates to the field of vehicle exhaust treatment, in particular to an exhaust treatment device. Background technique [0002] The main components of vehicle exhaust are CO, HC, NO x , solid particles and a small amount of lead, phosphorus, sulfur compounds and other harmful substances are the main factors causing air pollution. [0003] The vehicle exhaust treatment device currently used is mainly a three-way catalytic converter. The three-way catalytic converter is the most important external purification device installed in the vehicle exhaust system. Its shell is mostly made of double-layer stainless steel sheet, and the inside is composed of a shock absorber, a carrier and a catalyst coating. Shock absorbing pads are divided into expansion pads and steel wire mesh pads; the carrier is divided into metal carrier and honeycomb ceramic carrier, the main function is to support the active component, and a higher specific surface area ca...
