Abstract

The utility model discloses a combined corrosive liquid storage device and a catalytic flue gas desulfurization device, and solves the technical problems that a regenerated liquid tank is heavy in structure, high in construction cost, long in period and insufficient in corrosion resistance. Comprising a prefabricated storage tank, the main body of the prefabricated storage tank is made of a corrosion-resistant thermoplastic polymer, sleeves made of the corrosion-resistant thermoplastic polymer are distributed and installed in the prefabricated storage tank, and the two ends of each sleeve are installed on the two opposite side walls of the prefabricated storage tank respectively and are in sealed connection and conduction with a pair of corresponding side wall openings respectively; the supporting structure comprises an outer frame and pull rods, the outer frame is installed outside the prefabricated storage tank and used for containing and supporting the prefabricated storage tank, the pull rods are distributed and installed in the outer frame, the pull rods are arranged in the corresponding sleeves in a penetrating mode in a one-to-one correspondence mode, and the two ends of each pull rod are connected to the two opposite side walls of the outer frame in a pulling mode respectively. Factory prefabrication production is achieved, the site construction workload is greatly reduced, the site construction period is greatly shortened, civil engineering investment is reduced, and long-term safety and reliability of corrosive liquid storage are guaranteed.
