This utility model discloses an acetic anhydride distillation guiding and collecting device, relating to the field of acetic anhydride distillation technology. The utility model includes a support frame, with a guiding tank inserted inside the support frame. An inlet pipe is fixedly connected to the top of the guiding tank, and a drain pipe is fixedly connected to the bottom of the guiding tank. A collection bottle is disposed at the bottom of the drain pipe. It also includes a guiding mechanism disposed inside the guiding tank, comprising an inner tank fixedly connected to the inner wall of the guiding tank. This utility model, by setting guiding deceleration plates, specifically, guides and slows down acetic anhydride vapor after it enters the inner tank. Simultaneously, serpentine ribs further slow down the flow of acetic anhydride vapor. The multiple guiding deceleration plates cause the acetic anhydride vapor to flow in a serpentine manner, thereby ensuring more complete liquefaction of the acetic anhydride vapor, significantly reducing the escape loss of acetic anhydride vapor, and improving the yield.

This invention discloses a flue gas purification device for rubber production and processing, relating to the field of rubber processing flue gas purification technology. It includes a separation heat exchange cylinder, a dust collector, and a catalytic processor. The separation heat exchange cylinder has a top cover and further includes a hollow spiral cooling plate fixed inside the cylinder.
