A distillation tower for the recovery of tributyltin chloride

Abstract

This utility model discloses a distillation tower for recovering tributyltin chloride, relating to the field of tributyltin chloride recovery technology. It includes a shell, a filtration mechanism at the top of the shell, and a separation mechanism inside the shell. The separation mechanism includes a partition, a conduit, a baffle, a connecting pipe, and a protrusion. Two partitions are fixedly installed inside the shell, and the space between the top of the partition and the inner wall of the shell forms a water storage cavity. In the technical solution provided by this utility model, the separation mechanism allows steam from the heating chamber to flow into the conduit. As the steam flows through the conduit, it passes through the connecting pipe and the baffle, contacting the filtration mechanism at the top of the shell, where it condenses into water droplets. These droplets fall onto the baffle and are guided by the protrusion to fall into the water storage cavity through the flow outlet, allowing for rapid separation of water from the tributyltin chloride solution and resulting in higher distillation efficiency.

[0001] This utility model relates to the field of tributyltin chloride recovery technology, and in particular to a distillation tower for tributyltin chloride recovery. Background Technology

[0002] Chemical manufacturers use distillation towers during production to accelerate the generation of chemical substances. In the production of tributyltin chloride, a mixture of tetrabutyltin and anhydrous tin tetrachloride is heated, then cooled in air and then in water. After cooling, it is heated again, the reaction mixture is filtered, and the filtrate is distilled, which requires the use of a distillation tower.

[0003] The current distillation towers used for tributyltin chloride recovery have a slow cooling rate, resulting in low condensation efficiency, which significantly affects distillation efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a distillation tower for the recovery of tributyltin chloride, so as to solve the problem that the cooling rate of the prior art is slow, resulting in low condensation efficiency, which will have a significant impact on the distillation efficiency.

[0005] In view of this, the present invention provides a distillation tower for the recovery of tributyltin chloride, including a shell, a filtration mechanism at the top of the shell, and a separation mechanism inside the shell;

[0006] The separation mechanism includes a partition, a conduit, a baffle, a connecting pipe, and a protrusion. The partition is fixedly installed inside the housing. There are two partitions. The space between the top of the partition and the inner wall of the housing forms a water storage cavity, and the space between the bottom of the partition and the inner wall of the housing forms a heating cavity. The conduit is fixedly installed inside the partition, the baffle is fixedly installed on the inner wall of the conduit, the protrusion is fixedly installed on the top of the baffle, and the connecting pipe is fixedly installed inside the protrusion.

[0007] Optionally, the protrusion is hemispherical.

[0008] Optionally, the inner wall of the conduit is provided with a flow port that communicates with the water storage cavity.

[0009] Optionally, an installation plate is fixedly installed on the inner wall of the heating chamber, a heating device is fixedly installed at the bottom of the installation plate, and a heat-conducting element is fixedly installed at the output end of the heating device, the heat-conducting element being located inside the heating chamber.

[0010] Optionally, a heat sink is installed between the two partitions, the heat sink is fixedly installed on the side wall of the conduit, and ventilation holes are provided inside the housing.

Detailed Implementation

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a distillation tower for recovering tributyltin chloride according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of a distillation tower for recovering tributyltin chloride provided by this utility model includes a shell 1, a filtration mechanism at the top of the shell 1, and a separation mechanism inside the shell 1;

[0027] The separation mechanism includes a partition 18, a conduit 13, a baffle 14, a connecting pipe 15, and a protrusion 16. The partition 18 is fixedly installed inside the housing 1. There are two partitions 18. The space between the top of the partition 18 and the inner wall of the housing 1 forms a water storage chamber, and the space between the bottom of the partition 18 and the inner wall of the housing 1 forms a heating chamber. The conduit 13 is fixedly installed inside the partition 18. The baffle 14 is fixedly installed on the inner wall of the conduit 13. The protrusion 16 is fixedly installed on the top of the baffle 14. The connecting pipe 15 is fixedly installed inside the protrusion 16. The inner wall of the conduit 13 has a flow port 17 that communicates with the water storage chamber.

[0028] It should be noted that the inner diameter of the top of the connecting pipe 15 is smaller than that of the bottom. By setting the conduit 13, the steam in the heating chamber can flow into the conduit 13. When the steam flows in the conduit 13, it will pass through the connecting pipe 15 and the baffle 14, and come into contact with the filter mechanism at the top of the shell 1, thereby condensing into water droplets. The water droplets fall on the baffle 14 and are guided by the protrusion 16 to fall into the water storage chamber through the flow port 17.

[0029] In some embodiments, such as Figure 3 As shown, the protrusion 16 is hemispherical, and a heat sink 12 is installed between the two partitions 18. The heat sink 12 is fixedly installed on the side wall of the conduit 13, and a ventilation hole 5 is provided inside the housing 1.

[0030] It should be noted that by setting the ventilation holes 5, external air can circulate between the partitions 18 through the ventilation holes 5, thereby rapidly cooling the duct 13 through the heat sink 12 and making the condensation speed faster.

[0031] In some embodiments, such as Figure 2 As shown, an installation plate 10 is fixedly installed on the inner wall of the heating chamber, and a heating device 9 is fixedly installed at the bottom of the installation plate 10. A heat-conducting component 11 is fixedly installed at the output end of the heating device 9. The heat-conducting component 11 is located inside the heating chamber. A feed pipe 2 is fixedly installed on one side of the shell 1, and a discharge pipe 3 and a drain pipe 4 are fixedly installed on the other side of the shell 1. Both the feed pipe 2 and the discharge pipe 3 are connected to the heating chamber, and the drain pipe 4 is connected to the water storage chamber.

[0032] It should be noted that the heating device 9 can be an electric heating wire. The heating device 9 can be used to heat the heat-conducting component 11, thereby heating the liquid in the heating chamber and causing the water in the liquid to evaporate. Solenoid valves are installed in the feed pipe 2, the discharge pipe 3 and the drain pipe 4. The feed pipe 2 can be used to add the liquid to be distilled into the heating chamber. The discharge pipe 3 can be used to discharge the distilled tributyltin chloride solution. The drain pipe 4 can be used to discharge the condensate in the water storage chamber.

[0033] Example 2

[0034] In some embodiments, such as Figure 2 As shown, the filtration mechanism includes an exhaust pipe 6, a first filter screen 7, and a second filter screen 8. The exhaust pipe 6 is fixedly installed on the top of the housing 1, and the first filter screen 7 and the second filter screen 8 are both fixedly installed on the inner wall of the exhaust pipe 6. The first filter screen 7 is located at the bottom of the second filter screen 8.

[0035] It should be noted that by setting the first filter 7 and the second filter 8, the gas passing through the exhaust pipe 6 can be filtered to ensure the safety of the exhaust gas.

[0036] Working principle: During use, the liquid to be distilled can be added into the heating chamber through the feed pipe 2. Then, the heating device 9 can be used to heat the heat-conducting component 11, thereby heating the liquid in the heating chamber and causing the water in the liquid to evaporate. The steam in the heating chamber can flow into the conduit 13 through the conduit 13. When the steam flows in the conduit 13, it will pass through the connecting pipe 15 and the baffle 14, and come into contact with the filter mechanism at the top of the shell 1, thereby condensing into water droplets. The water droplets fall on the baffle 14 and are guided by the protrusion 16 to fall into the water storage chamber through the flow port 17. The ventilation hole 5 allows the outside air to flow through the ventilation hole 5 between the partitions 18, thereby rapidly cooling the conduit 13 through the heat sink 12, making the condensation speed faster. The distilled tributyltin chloride solution can be discharged through the discharge pipe 3, and the condensate in the water storage chamber can be discharged through the drain pipe 4.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
