This utility model relates to the technical field of waste heat recovery systems in sulfuric acid plants, specifically a tube bundle fixing structure for a sulfuric acid steam generator. In traditional steam generators, the tube box, the tube sheet of the U-shaped tube bundle, and the shell-side cylinder are directly connected via the same set of flanges. During maintenance and repair of the U-shaped tube bundle, the flange connection needs to be disassembled, causing the tube box, U-shaped tube bundle, and shell-side cylinder to loosen, and the sealing gaskets used for connection and sealing to wear down, affecting the sealing effect. Therefore, this invention adds a short cylindrical section between the tube sheet of the U-shaped tube bundle and the shell-side cylinder, and uses a short cylindrical flange on the short cylindrical section to connect to the shell-side cylinder. During maintenance of the U-shaped tube bundle, only the connection between the tube box and the tube sheet of the U-shaped tube bundle needs to be disassembled. Since the U-shaped tube bundle is connected to the shell-side cylinder via the short cylindrical section, disassembly does not affect the seal between the U-shaped tube bundle and the shell-side cylinder. This reduces wear on the sealing components and makes disassembly and assembly quicker and more convenient.
