An environmental protection treatment device for automobile exhaust, composed of three element catalytic converter, a gas inlet and a gas outlet and nickel metal mesh grid is provided in three element catalytic converter, nickel metal mesh grid is arranged on the catalyst coating, between the nickel metal mesh grille is arranged in the inlet and exhaust ports, and the three way catalytic converter automobile exhaust heat exchange device is arranged between the tube. The air inlet is connected with the exhaust pipe of the automobile exhaust. High temperature exhaust gas discharged by the engine enters the three way catalytic converter is composed of an air inlet, and the nickel metal mesh grille, reacts with the catalyst coating of nickel metal mesh on the gate, waste heat heating reaction heat from the exhaust pipe. After the reaction, the waste gas becomes harmless substances such as carbon dioxide, nitrogen gas and water. The invention avoids the problem that the three element catalytic converter is easy to lose catalytic action due to high temperature.
