Pipeline fixing device for welding desulfurization tower

The utility model discloses a pipeline fixing device for welding a desulfurizing tower, and relates to the technical field of desulfurizing towers. The pipeline fixing device for welding the desulfurizing tower comprises a transverse plate and a cooling mechanism, two sets of electric push rods are hinged to the top of the transverse plate through two sets of hinge blocks, two sets of L-shaped connecting plates are fixedly installed at the top of the transverse plate through bolts, and a bent plate A and a bent plate B are arranged at the tops of the two sets of L-shaped connecting plates. According to the pipeline fixing device for welding the desulfurizing tower, through cooperative use of a water storage tank, a hose, a sponge pad, a water inlet pipe and a water outlet pipe, a pipeline can be cooled while being welded by a worker, damage to the pipeline during welding is effectively reduced, a heat affected zone is reduced, the situation that the pipeline deforms during welding is reduced, and the working
