The invention belongs to the field of battery experiments, in particular to a power battery test smoke and exhaust gas treatment system, comprising a combustion chamber, an exhaust gas output end of the combustion chamber is connected with an exhaust gas treatment component, and the exhaust gas treatment component includes a cyclone dust collector, a pulse bag filter, a UV Photolysis + activated carbon adsorption integrated equipment, alkali washing spray tower. In the present invention, a connecting shaft is arranged in the box, and the connecting shaft is manually pulled to drive the connecting rod to move, so that the compression spring is compressed, so that the rubber plate is pressed down and deformed, and the movement of the connecting shaft drives the supporting plate to move downward and pull the filter bag, so that the filter bag is deformed , Release the connecting shaft, the compression spring resets to make the filter bag vibrate, and then the dust on the filter bag is loosened by vibration, and at the same time, the connecting shaft is rotated to make the connecting rod rotate, and the connecting rod drives the rubber plate to rub against the inner wall of the box, so that the inside of the box is rubbed. Dust is cleaner when removed.
