Description

Desulfurizing tower capable of carrying out endoscopic examination Technical Field The utility model relates to the technical field of desulfurizing towers, in particular to a desulfurizing tower capable of carrying out endoscopic examination. Background In the aluminum electrolysis production, due to the technical development and the environmental protection requirement of flue gas emission, the electrolytic flue gas purification system is required to be provided with a flue gas purification desulfurization system, along with the service time increase of each electrolytic aluminum enterprise desulfurization system, internal components such as inner wall glass flakes of a desulfurization tower, an inner demister, a spraying layer and the like have uncontrollable factors such as aging, scouring, stripping, falling, mechanical damage and the like, so that the inner wall glass flakes of the desulfurization tower, the inner demister, the spraying layer and the like are aged and damaged to different degrees, the safe and stable operation of the desulfurization system is influenced, at the moment, the periodic inspection of the inside of the desulfurization tower becomes an indispensable management and control measure, the operation of the desulfurization system is stopped, manhole door personnel are opened to enter the inside for inspection, the inspection mode is required to close a flue valve, the desulfurization tower is stopped for limited space operation, great consumption of manpower, material resources and financial resources is caused, and the risk of instantaneous exceeding of electrolytic flue gas emission is borne. Disclosure of utility model The utility model mainly aims to provide a desulfurizing tower capable of carrying out endoscopic examination, which aims to solve the problems that the desulfurizing tower in the prior art needs to be stopped for limited space operation during the internal examination of the desulfurizing tower, so that great consumption of manpower, material resources and financial resources is caused, and the instantaneous exceeding standard risk of the electrolysis flue gas emission is borne. In order to achieve the above purpose, the utility model provides a desulfurization tower capable of carrying out endoscopic examination, which comprises a tower body, wherein an inspection tube is fixedly connected to the side wall of the tower body, the outer end of the inspection tube is positioned at the outer side of the tower body, the inner end of the inspection tube is positioned at the inner side of the tower body, a duckbill-shaped blocking bag for preventing smoke from being discharged out of the tower body is arranged in the inspection tube, the blocking bag is made of tetrafluororubber, one end of the blocking bag is provided with a round opening which is connected with the inspection tube and faces the outer side of the tower body, and the other end of the blocking bag is an elongated flat opening which faces the inner side of the tower body. Further, the inspection tube comprises an outer tube and an inner tube, wherein the inner end of the inner tube is positioned in the outer tube and fixedly connected with the blocking bag, the outer end of the inner tube is positioned outside the outer tube, the outer wall of the inner tube is provided with a convex ring, and the convex ring is fixedly connected with the outer end of the outer tube through a nut. Further, a gasket is arranged at the joint of the convex ring and the outer tube. Further, the outer end of the inspection tube is detachably and fixedly connected with an end cover. The utility model is convenient to extend the industrial endoscope into the desulfurizing tower for inspection through the inspection pipe by arranging the inspection pipe, does not need to stop the desulfurizing tower and enter a limited space by workers during inspection, and can block the inspection pipe when the industrial endoscope extends into the inspection by arranging the blocking bag, so that the exhaust of the flue gas in the desulfurizing tower through the inspection pipe is reduced as far as possible.
