Power battery test smoke waste gas treatment system and treatment method thereof

The invention belongs to the field of battery experiments, and particularly relates to a power battery test smoke waste gas treatment system, which comprises a combustion chamber, the waste gas output end of the combustion chamber is communicated with a waste gas treatment assembly, and the waste gas treatment assembly comprises a cyclone dust collector, a pulse bag type dust collector, UV photolysis and activated carbon adsorption integrated equipment and an alkali washing spray tower. A connecting shaft is arranged in the box body, the connecting shaft is manually pulled to drive a connecting rod to move, so that a compression spring is compressed, a rubber plate is pressed downwards to deform, the connecting shaft moves to drive a supporting plate to move downwards to pull a filter bag, the filter bag deforms, the connecting shaft is loosened, the compression spring is reset, the filter bag vibrates, and then dust on the filter bag is vibrated to be loosened; meanwhile, a connecting rod is rotated by rotat
