Problems solved by technology
[0003] The heat exchange tube is the key part of the reboiler, which is the most sensitive to vibration, and is most likely to be damaged in the bending area where the fluid induces vibration. The large-scale reboiler makes the flow rate of the fluid entering the reboiler too high, directly impacting the heat exchange tubes, causing strong vibration of the heat exchange tubes, such long-term use will cause the heat exchange tubes to crack and fail

Embodiment Construction
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0027] see Figure 1-7 , a fractionation column reboiler, comprising a reboiler body 1, two soft bellows 2 are fixedly connected to the inner wall of the reboiler body 1, and heat exchange tubes are fixedly connected to the opposite surfaces of the two soft bellows 2 3. The upper surface of the reboiler body 1 is fixedly connected with an oil tank 14 and a buffer tank 15, and the inner wall of the buffer tank 15 is fixedly connected with a three-stage spring 1...

The invention relates to the technical field of heat exchangers, and discloses a fractionating tower reboiler which comprises a reboiler body, two soft corrugated pipes are fixedly connected to the inner wall of the reboiler body, heat exchange pipes are fixedly connected to the opposite faces of the two soft corrugated pipes, an oil tank and a buffer tank are fixedly connected to the upper surface of the reboiler body, and third-stage springs are fixedly connected to the inner wall of the buffer tank. According to the fractionating tower reboiler, oil in the oil tank is squeezed into the buffer tank through cooperation of moving rods and moving blocks, vibration of a heat exchange pipe in the vertical direction can be reduced through second-stage springs and vibration reduction plates, and front-back movement of a U-shaped frame is facilitated through cooperation of first-stage springs, grooves and sliding blocks; and meanwhile, vibration in the front-back direction of the heat exchange pipe is reduced through the combined action with a sponge pad, and therefore the problems that the heat exchange pipe is damaged most easily in a bending area where vibration is induced by fluid, and the heat exchange pipe is cracked and fails after being used all the year round are solved.
Description
technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a fractionation tower reboiler. Background technique [0002] Fractionation reboiler is a material-liquid separation equipment widely used in chemical industry, petroleum, energy, power, metallurgy and other industrial sectors. Fractionation tower and reboiler are used in combination. A special heat exchanger that provides energy for vaporization of the incoming feed liquid. [0003] The heat exchange tube is the key part of the reboiler, which is the most sensitive to vibration, and is most likely to be damaged in the bending area where the fluid induces vibration. The large-scale reboiler makes the flow rate of the fluid entering the reboiler too high, directly impacting the heat exchange tubes, causing strong vibration of the heat exchange tubes, such perennial use will cause the heat exchange tubes to crack and fail. Contents of the invention [0004] Aiming at th...
