Vertical type sleeving device of pipe bundle assembly of heavy floating head heat exchanger

Abstract

The invention discloses a vertical type sleeving device of a pipe bundle assembly of a heavy floating head heat exchanger. The vertical type sleeving device comprises an upper hoop 7 and a lower hoop 10. The upper hoop 7 and the lower hoop 10 are used for fixing the pipe bundle assembly. Fixation of the hoops and the pipe bundle assembly is completed on a pipe bundle assembling and welding platform, the barrel simulation effect is achieved, it is ensured that pipe bundles are not bent or moved in the erecting process, the pipe bundle assembly is well protected, vertical hoisting of the pipe bundle assembly is achieved, and difficulty and risks caused by horizontal sleeving are avoided. The device is novel in structure, high in practicability, convenient to detach and capable of being repeatedly used. The pipe bundle assembly can be hoisted to an acid pickling site from the pipe bundle assembling and welding platform to be subjected to acid pickling and passivating operation of stainless steel surfaces after pipe end and pipe plate welding. Rolling can be achieved on a roller frame, and automatic welding operation of a circumferential weld of an end socket assembly and an upper pipe plate is completed.

Description

technical field [0001] The invention relates to the technical field of thermal engineering, in particular to a vertical set device for a tube bundle assembly of a heavy-duty floating head heat exchanger. Background technique [0002] The air-gas heat exchanger is a floating head heat exchanger with a total length of 17.5 meters, a diameter of 1.9 meters and a net weight of 95.5 tons; the weight of the tube bundle assembly is 45.1 tons, and the length of the cylinder is 12 meters. [0003] Due to the long cylinder and the heavy weight of the tube bundle components, there are many difficulties and disadvantages in the horizontal casing, such as ① due to the heavy weight of the tube bundle components, the friction between the tube bundle components and the cylinder is relatively large, and the introduction of the cylinder is difficult; ②There is only a 4mm gap between the tube bundle support plate and the inner wall of the cylinder, which is difficult to adjust during introduct...

Problems solved by technology

[0003] Due to the long cylinder and the heavy weight of the tube bundle components, there are many difficulties and disadvantages in the horizontal casing, such as ① due to the heavy weight of the tube bundle components, the friction between the tube bundle components and the cylinder is relatively large, and the introduction of the cylinder is difficult; ②There is only a 4mm gap between the tube bundle support plate and the inner wall of the cylinder, which is difficult to adjust during introduction; body splicing, the amount of misalignment can meet the standard, but it is difficult to ensure the horizontal package requirements; ④Due to the heavy weight of the tube bundle components, there may be a risk of the tube bundle scratching the tube wall or even the tube bundle support plate and the tube body being stuck; ⑤Cylinder body It is difficult to adjust the misalignment with the lower tube plate after assembly

[0004] The above-mentioned difficulties can be avoided if the tube bundle assembly is installed vertically, but if the tube bundle is directly erected, the tube bundle will be bent and deformed, and there is no lifting point
