Abstract
The utility model relates to a reboiler used for preventing a pipe column from vibrating. The reboiler used for preventing the pipe column from vibrating comprises the reboiler, the reboiler is characterized in that the outlet of a shell side of the reboiler is provided with a support ring, and the inlet of the shell side is provided with a scour prevention pipe. The reboiler provided by the utility model has the advantages that the structure is simple, the pressure drop of the shell side is not increased, the vibration breakage of a heat exchange tube is effectively avoided, the normal operation of the reboiler is guaranteed, and the service life of the reboiler is prolonged.
Description
Technical field
The utility model relates to a kind of reboiler of anti-tube bundle vibration.
Background technology
Reboiler is the equipment of oil, chemical field boiling heat transfer; Mainly be used for required thermal source being provided to the tower distillation process; Its operation principle is that liquid medium gets into enclosure interior from the shell side below, is heated vaporization at shell side, and steam after the vaporization and liquid mixture get in the tower from outlet; Whole process is to utilize before and after the medium vaporization density different and differential static pressure that form is realized Automatic Cycle, does not need additionaling power.Because the tower distillation process needs a large amount of thermals source,, be easy to cause heat exchanger tube flutter failure so the flowing velocity of reboiler import and export medium is very big.Too high for preventing import department's flow rate of liquid, traditional reboiler generally can be provided with impingement baffle, but can cause near the flow rate of liquid of the regional area of impingement baffle too high after impingement baffle is set, and heat exchanger tube produces vibration very soon and lost efficacy.In addition, because of reboiler shell side medium is an Automatic Cycle, so that the shell side required pressure falls is very little, pressure falls to exceed standard and will cause the shell side medium can't carry out Automatic Cycle, thereby influences the quality of rectifying product.Reboiler has housing, heat exchanger tube, deflection plate and support plate, and heat exchanger tube places the housing inner chamber, and relative heat exchanger tube is provided with deflection plate and support plate in the housing inner chamber.Traditional shell-and-tube reboiler, baffle(s) spacing is bigger, and the heat exchanger tube vibration damage often takes place in the position bigger at shell side import and export velocity of medium.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of reboiler that can overcome the anti-tube bundle vibration of above-mentioned defective is provided, can effectively avoids heat exchanger tube vibration causing reboiler to damage.
The utility model solves the technical scheme that its technical problem adopted: a kind of reboiler of anti-tube bundle vibration, comprise reboiler, and it is characterized in that the shell side exit of described reboiler is provided with bracing ring, the import department of shell side is provided with anti-washing pipe.
In the described bracing ring is grid-like.
Described anti-washing pipe is the import department that a row or two rows are arranged on shell side, and the heat exchanger tube in anti-washing pipe and the reboiler parallels.
The beneficial effect that the utility model had is: simple in structure, and do not increase shell side pressure and fall, can effectively avoid the vibration damage of heat exchanger tube, guarantee the reboiler normal running, improve the service life of reboiler.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the bracing ring structural representation;
Among the figure: 1, reboiler; 2, bracing ring; 3, anti-washing pipe; 4, grid space.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Reboiler like the anti-tube bundle vibration of Fig. 1～shown in Figure 2 comprises reboiler 1, and the shell side exit of described reboiler 1 is provided with bracing ring 2, and the import department of shell side is provided with anti-washing pipe 3.In the bracing ring 2 is grid-like.Anti-washing pipe 3 is the import department that a row or two rows are arranged on shell side, and the heat exchanger tube in anti-washing pipe 3 and the reboiler 1 parallels.
Heat exchanger tube passes the grid space 4 exchange heat pipes of bracing ring 2 and plays a supporting role, and anti-washing pipe 3 plays the effect of erosion control and shunting, and really the flow rate of liquid of shell side import department does not increase, and improves the service life of reboiler 1.
