Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and more specifically to an anti-clogging propane removal tower reboiler structure. Background Art

[0002] The reboiler plays a vital role in the distillation tower. Its main function is to vaporize the liquid again by heating, providing the necessary vapor phase for the distillation process. This vaporization process not only helps to prevent the "dry plate" phenomenon in the distillation tower and ensures that there is always enough liquid on the tower plate, but also significantly improves the stability and efficiency of the distillation process by maintaining the pressure in the tower and improving the contact mass transfer efficiency between the vapor and liquid phases. In addition, the reboiler also ensures the quality of the distillate, allowing different components in the mixture to be separated more effectively.

[0003] When a distillation tower is used to remove propane, the feed to the distillation tower is the oil phase after alkali washing and water washing. This material will contain a certain amount of sodium salt. When the reboiler heats the distillation tower, the sodium salt is easily precipitated in the distillation tower, and the pipe mouth at the interface of the reboiler is adhered and adsorbed to cause blockage. If blockage occurs, the heat exchange effect is reduced, which will cause the device to stop completely and the process production cannot be carried out, resulting in huge economic losses. The reboiler needs to be disassembled and cleaned, which seriously affects the production efficiency. A device is needed to clean the sodium salt that is blocked at the pipe mouth of the reboiler.

[0004] In view of this, the utility model provides a propane removal tower reboiler structure that is anti-clogging. Utility Model Content

[0010] As a further improvement of the technical solution, the valve assembly includes a closing valve, the top of the closing valve is movably connected to a rotating rod, and the top of the rotating rod is fixedly installed with a rotating ring.

[0011] As a further improvement of the technical solution, the closing valve is installed inside the mounting groove, and the top of the rotating rod passes through the mounting sleeve and extends to the inside of the rotating ring.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] like Figure 1-4 As shown, the device includes a reboiler body 1, a pipe 2 connected to the top of a distillation tower is installed on the top of the outer wall of the reboiler body 1, a pipe 2 connected to the outer wall of the distillation tower is installed on the bottom of the outer wall of the reboiler body 1, a flushing pipe 4 for flushing the sodium salt blocked in the reboiler body 1 is installed on the outer wall of the pipe 2 3, an opening and closing component 5 for opening and closing the flushing pipe 4 is installed on the outer surface of the flushing pipe 4, and a control component 6 for controlling the flushing water flow is provided on the outer wall of the pipe 2 3.

[0022] By installing a flushing pipe 4 on the pipe 2 3 connecting the distillation tower and the reboiler body 1, the water flow in the flushing pipe 4 is controlled by the opening and closing component 5 and the control component 6, and the sodium salt that is blocked at the pipe mouth of the reboiler body 1 is flushed to avoid blockage at the pipe mouth of the reboiler body 1.

[0023] First, the specific structure of the opening and closing component 5 is disclosed. The opening and closing component 5 includes a switch valve 3 501, and the switch valve 3 501 controls the flow of flushing water in the flushing pipe 4. The switch valve 1 301 is installed on the left side of the connection between the outer wall of the pipe 2 3 and the flushing pipe 4, and the switch valve 2 302 is installed on the right side of the connection between the outer wall of the pipe 2 3 and the flushing pipe 4.

[0024] When the reboiler body 1 provides the gas phase to the distillation tower, the switch valve 1 301 and the switch valve 2 302 are opened, and the switch valve 3 501 is closed, so that the gas phase flows in the distillation tower and the reboiler body 1. When the sodium salt adhering to the reboiler body 1 is to be flushed, the switch valve 1 301 is closed, and the switch valve 2 302 and the switch valve 3 501 are opened, so that the water flow transported in the flushing pipe 4 flushes the pipe mouth pair of the reboiler body 1, and the sodium salt adhering and clogging is flushed, so as to achieve the effect of preventing the sodium salt from adhering and clogging the reboiler body 1.

[0025] According to the above disclosure of the specific structure of the control component 6, the control component 6 includes a mounting sleeve 601 that is docked and installed inside the pipe 2 3, a fixing ring 602 is installed inside the mounting sleeve 601, a plurality of through water holes 603 are provided inside the fixing ring 602, a mounting groove 604 is provided on the outer surface of the fixing ring 602, and a valve component 7 that opens and closes the mounting groove 604 is installed inside the mounting groove 604.

[0026] The valve assembly 7 includes a closing valve 701, the top of the closing valve 701 is movably connected to a rotating rod 702, and the top of the rotating rod 702 is fixedly installed with a rotating ring 703. The closing valve 701 is installed inside the installation groove 604, and the top of the rotating rod 702 penetrates the installation sleeve 601 and extends to the inside of the rotating ring 703. The rotating ring 703 rotates to drive the rotating rod 702 to rotate, so that the closing valve 701 rises to open the installation groove 604.

[0027] When the water in the flushing pipe 4 enters the installation sleeve 601 through the switch valve three 501 and the switch valve two 302, the sodium salt adhesion is not easy to be flushed out. The rotating rod 702 is rotated to make the closing valve 701 close the installation groove 604 of the fixed ring 602 in the installation sleeve 601. The water flow can only flow out through the water flow hole 603 opened on the fixed ring 602. The flushing force of the water flow can be strengthened, and it is easier to flush out the adhered sodium salt. After flushing for a certain period of time, the rotating rod 702 is rotated again to make the closing valve 701 rise, open the installation groove 604, increase the water flow, and thoroughly flush out the sodium salt, thereby achieving the effect of flushing and cleaning the sodium salt blocked inside the reboiler body 1.

[0028] In summary, the working principle of this solution is as follows:

[0029] When the reboiler body 1 provides the gas phase to the distillation tower, the switch valve 1 301 and the switch valve 2 302 are opened, and the switch valve 3 501 is closed, so that the gas phase flows in the distillation tower and the reboiler body 1. When the sodium salt adhering to the reboiler body 1 is to be flushed, the switch valve 1 301 is closed, and the switch valve 2 302 and the switch valve 3 501 are opened, so that the water flow transported in the flushing pipe 4 flushes the pipe mouth pair of the reboiler body 1, and the sodium salt adhering and clogging is flushed, so as to achieve the effect of preventing the sodium salt from adhering and clogging the reboiler body 1.

[0030] When the water in the flushing pipe 4 enters the installation sleeve 601 through the switch valve three 501 and the switch valve two 302, the sodium salt adhesion is not easy to be flushed out. The rotating rod 702 is rotated to make the closing valve 701 close the installation groove 604 of the fixed ring 602 in the installation sleeve 601. The water flow can only flow out through the water flow hole 603 opened on the fixed ring 602. The flushing force of the water flow can be strengthened, and it is easier to flush out the adhered sodium salt. After flushing for a certain period of time, the rotating rod 702 is rotated again to make the closing valve 701 rise, open the installation groove 604, increase the water flow, and thoroughly flush out the sodium salt, thereby achieving the effect of flushing and cleaning the sodium salt blocked inside the reboiler body 1.
