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. A column is fixed in the middle of the hollow spiral cooling plate, which is filled with flowing coolant. Adjacent spirals of the hollow spiral cooling plate cooperate with the inner wall of the separation heat exchange cylinder to form a flue gas spiral flow channel. Two sealing plates are fixed on the inner wall of the separation heat exchange cylinder, located at opposite ends of the flue gas spiral flow channel. This invention integrates flue gas spiral heat exchange, centrifugal oil-gas separation, wall anti-clogging, and self-driven enhanced heat exchange into a single unit, meeting the comprehensive requirements of high-efficiency separation, waste heat recovery, long-term anti-clogging, and low-consumption operation in rubber flue gas treatment.

The utility model relates to the technical field of industrial flue gas treatment, and discloses a system for recovering sulfur in sulfur-containing flue gas, which comprises a cooling and condensing device, a bag-type dust collector and a tail gas washing system, and the cooling and condensing device comprises a high-temperature condensing assembly, a low-temperature condensing assembly, a connecting box and an anti-blocking assembly, the cooling and condensing device composed of the high-temperature condensing assembly and the low-temperature condensing assembly is adopted, graded cooling is carried out according to different phase change temperatures of sulfur, the high-temperature condensing assembly preliminarily cools high-temperature sulfur-containing flue gas to 150-200 DEG C, most of sulfur steam is efficiently condensed into liquid sulfur, and the temperature interval ensures that the sulfur steam is fully liquefied, and the sulfur steam can be efficiently condensed into liquid sulfur. And then, the flue gas is further cooled to 80-120 DEG C by the low-temperature condensation assembly, so that the residual sulfur steam is condensed into solid sulfur, the sulfur in the flue gas can be fully recovered by the stage treatment mode, and the recovery rate of the sulfur is greatly improved.
