The structure of the heat exchanger is similar to that of a condenser, but one of the heat exchanger and the reboiler is used for cooling, the reboiler is used for heating and vaporizing, and the reboiler is mostly used together with a fractionating tower. The level of feed in the reboiler and the level of the fractionation column are at the same height. The liquid phase is supplied from the bottom line into the reboiler. Typically 25-30% of the liquid phase is vaporized in the reboiler. The vaporized two-phase flow is sent back to the fractionating tower, the gas-phase component in the returned tower passes through the tray upwards, the liquid-phase component drops back to the tower bottom, the material is heated and expanded in the reboiler and even vaporized, the density becomes small, the material leaves the vaporization space and returns to the tower smoothly, the gas-liquid two-phase in the returned tower, the gas phase passes through the tray upwards, and the liquid phase drops to the tower bottom. The bottom of the column will be constantly replenished with the part of the liquid level that is evaporated due to the static pressure difference.

During operation, the heat exchange tubes 17 are easy to bend and deform due to gravity due to lack of support among the heat exchange tubes 17, so that normal use of the heat exchange tubes 17 is influenced.

As an embodiment of the present invention, as shown in fig. 5 and 7, the gasket 24 and the annular groove 23 are engaged with each other in a T-shaped structure, and the first slider 43 and the first runner 42, the second slider 44 and the second runner 45, and the third slider 47 and the second runner 45 are also engaged with each other in a T-shaped structure.

When the heat exchange pipe 17 works, the sealing gasket 24 is easy to wear after being used for a long time, so that the sealing effect of the sealing gasket is influenced, the sealing gasket 24 is convenient to disassemble and assemble by mutually clamping the sealing gasket 24 and the annular groove 23 in a T-shaped structure, the sealing gasket 24 is prevented from being worn after being used for a long time, so that the sealing effect of the sealing gasket 24 is influenced, the first sliding block 43 and the first sliding groove 42, the second sliding block 44 and the second sliding groove 45 and the third sliding block 47 and the second sliding groove 45 are also mutually clamped in a T-shaped structure, so that stress is generated between the first sliding block 43 and the sliding groove, between the second sliding block 44 and the second sliding groove 45 and between the third sliding block 47 and the second sliding groove 45, and the heat exchange pipe 17 is better supported and fixed.

As an embodiment of the present invention, as shown in fig. 7, a limiting groove 26 is formed on an inner surface of the annular groove 23 near the opening, and a limiting plate 27 is fixedly connected to the inner surface of the limiting groove 26 by a screw.

In the working process, the sealing gasket 24 needs to be replaced, so that the sealing gasket 24 is not tightly connected with the annular groove 23, the sealing gasket 24 is easily separated from the annular groove 23, and the sealing effect of the sealing gasket 24 is influenced.

The working principle is as follows: the invention arranges the connecting mechanism 2, when the heat exchange tube 17 is damaged, firstly, the front sealing cylinder 11, the rear sealing cylinder 12 and the liquid in the heat exchange tube 17 are emptied and dried, then the water outlet tube 14 and the feed tube 15 are closed, water is added into the water inlet tube 13, a water pump connected with the water outlet tube 16 is started, so that the water in the main shell 1 enters the heat exchange tube 17 from the damaged part of the heat exchange tube 17 and flows out to the rear sealing cylinder 12, then the screw is screwed to separate the first flange 21 from the second flange 22, thereby separating the rear sealing cylinder 12 from the main shell 1, because the inner wall of the damaged heat exchange tube 17 is wetted by water, the wetted state of the inner wall of the heat exchange tube 17 can be detected, which heat exchange tube 17 is damaged, by arranging the fixing mechanism 3, when the heat exchange tube 17 needs to be maintained, the damaged heat exchange tube 17 is detected firstly, then the rear sealing cylinder 12 is disassembled, and then the first connecting plate 33 or the second connecting plate 34 connected with the damaged heat exchange tube 17 is taken out, when taking out the second connecting plate 34, the first slider 43 slides along the first sliding groove 42, and the second slider 44 slides along the second sliding groove 45, so as to support the second connecting plate 34, and when taking out the first connecting plate 33, the first connecting plate 33 is supported by mutually attaching the first sliders 43 and the first sliding grooves 42.

The electric elements in the document are electrically connected with an external main controller and 220V mains supply through a transformer, the main controller can be a conventional known device controlled by a computer and the like, the product model provided by the invention is only used according to the structural characteristics of the product, the product can be adjusted and modified after being purchased, so that the product is more matched with and accords with the technical scheme of the invention, the product model is a technical scheme of the optimal application of the technical scheme, the product model can be replaced and modified according to the required technical parameters, and the product model is familiar to the technical personnel in the field, so that the technical scheme provided by the invention can clearly obtain the corresponding use effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
