The present invention discloses a VOCs treatment system, which relates to the technical field of waste gas treatment. When a VOCs concentration detection sensor detects that the exhaust gas concentration reaches a certain value, an electric telescopic rod is started through a controller, and the electric telescopic rod begins to extend and pushes down an upper fixed plate, so that the upper fixed plate drives two symmetrical telescopic pipes at the upper ends to fall synchronously. At the same time, the upper fixed plate exerts a downward squeezing effect on the upper ends of two spiral shells, so that the two spiral shells together with the catalytic units inside are gradually compressed. At this time, the spiral amplitude of the spiral shell increases, and the rising speed of the exhaust gas in the spiral shell is reduced again, and the contact time with the inner wall of the channel is increased again, thereby further improving the adsorption efficiency of the catalytic unit. At the same time, when the VOCs concentration of the exhaust gas is lower than the qualified range, the spiral shell begins to reset to the initial state, so as to always keep the catalytic unit inside the spiral shell with a high-efficiency adsorption effect.
