Acetone washing device capable of improving suction effect of volatile gas

The utility model relates to an acetone washing device capable of improving a suction effect of volatile gas, and the acetone washing device comprises an acetone washing trough, a steam valve, a nitrogen valve, a spinneret cap hanger and a VTA (stainless steel pipe orifice) suction port, and the acetone washing device is characterized in that a copper VTA arc guide plate is arranged above the VTA suction port 6 of the acetone washing trough to form a suction guide device. Due to the adoption of the acetone washing device, acetone gas volatized from the acetone washing trough can be inhibited to form airflow to be rapidly sucked through the VTA suction port below the arc guide plate, so that workers can be basically prevented from smelling the acetone when standing by the acetone washing trough and repeatedly washing each cap hung on the spinneret cap hanger immersed in hot acetone liquid through a piece of silk cloth inside the opened acetone washing trough. The operation personnel are safer by the side of th
