The invention discloses a dielectric barrier discharge tube based on a needle type collaborative double-helix electrode. The dielectric barrier discharge tube comprises a quartz tube, the middle of the quartz tube is sleeved with a high-voltage electrode, an inner electrode is arranged in the quartz tube, a driving fan is arranged at the end of the inner electrode, a spray point set is arranged on the surface of the inner electrode, and a spiral discharge wire is erected at the tip of the spray point set in a suspended mode. After a high-voltage electric field is externally applied to the high-voltage electrode, the spray point group and the spiral discharge wire discharge, so that the discharge area in the quartz tube can be enlarged, the discharge sequences are different, and the treatment effect and adaptability to target gas are improved; when the gas passes through the driving fan, the flow direction of the gas is changed, so that the effect of disturbing the gas flow is achieved. The contact area of the
