Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of distillation towers, and in particular relates to a distillation tower condensing device. Background Art
[0002] A distillation tower, also known as a rectification column or a distillation tower, is a device used to separate different components in a liquid mixture. It is one of the common devices in chemical engineering and petroleum industry. The distillation tower uses the difference in boiling points between the components to separate the components in the mixture, and the condensing device of the distillation tower is a heat exchanger, which is used to cool the steam output from the top of the distillation tower into liquid, thereby taking away the heat.
[0003] The utility model patent with authorization announcement number: CN209548747U discloses a distillation tower condensation device, including a horizontally placed elliptical condenser body, a condensate outlet end and a condensate inlet end arranged on both sides of the condenser body, a material inlet, a material outlet and a spoiler are arranged on the condenser body, the material inlet is arranged on one side of the top end of the condenser body, and the material outlet is arranged on the other side of the bottom end of the condenser body, and the spoiler is specifically a curved plate and is provided in multiple groups, fixedly arranged at the top and bottom ends of the inner wall of the condensing body, and adjacent spoilers are located at the top and bottom ends respectively. The curved spoiler has a larger contact area than the straight plate at the same vertical distance, so that the chemical material can be condensed more thoroughly; similarly, liquid will not accumulate on the curved spoiler, avoiding the situation where the liquid material after the material condensation accumulates on the spoiler and cannot be cleaned.
[0004] During actual use, steam enters multiple material inlets through the connecting pipe, and then enters the spoiler from the material inlet to condense. However, different logistics inlets are at different distances from the material outlet, so the condensation effect of the steam is also different. Steam at a closer distance is difficult to condense effectively, which affects the condensation performance and stability of the device.
[0005] Therefore, it is necessary to provide a new distillation tower condensing device to solve the above technical problems. Utility Model Content

[0009] In order to achieve the effect of cooling liquid flowing out, preferably, the outer side of the top of the steam flow cavity is connected with a second connecting pipe, and the other end of the second connecting pipe is connected with the condensation outer cavity.

[0016] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0017] Please refer to Figure 1 ,in Figure 1 The overall structure diagram of the distillation tower condensation device of the utility model is shown in FIG. The distillation tower condensation device comprises a condensation mechanism 1, which is used to cool the steam flowing through the condensation mechanism 1. The condensation mechanism 1 comprises a condensation outer chamber 11, a liquid inlet 2 is arranged on the outer side of the bottom of the condensation outer chamber 11, and a liquid outlet 3 is arranged on the outer side of the top of the condensation outer chamber 11.
[0018] In the specific implementation process, Figure 1 As shown, the interior of the condensation outer chamber 11 is hollow, the interior of the condensation outer chamber 11 is connected with a first connecting pipe 14 , one end of the first connecting pipe 14 is connected with the condensation inner chamber 12 , and a steam flow chamber 13 is provided between the condensation inner chamber 12 and the condensation outer chamber 11 .
[0019] refer to Figure 1 As shown, the outer side of the top of the steam flow chamber 13 is connected with a second connecting pipe 15 , and the other end of the second connecting pipe 15 is connected with the condensation outer chamber 11 .
[0020] refer to Figure 1 As shown, a feed port 16 is disposed at the top of the condensation outer chamber 11 , and a discharge port 17 is disposed at the bottom of the condensation outer chamber 11 . Both the feed port 16 and the discharge port 17 are connected to the steam flow chamber 13 .
[0021] refer to Figure 1 As shown, a flow valve 4 is provided at one end of the liquid inlet 2, and a supply pump 5 is provided at one side of the flow valve 4.
[0022] It should be noted that the interior of the condensation outer chamber 11 is hollow and is used for the flow of cooling liquid. The condensation outer chamber 11 is connected to the condensation inner chamber 12 through the first connecting tube 14 and the second connecting tube 15. The steam flow chamber 13 is used for the flow of steam to be cooled. The interior of the condensation inner chamber 12 is hollow and is used for the flow of cooling liquid.
[0023] The working principle of a distillation tower condensing device provided by the utility model is as follows:
[0024] When in use, steam enters the steam flow chamber 13 from the feed port 16 and flows out from the discharge port 17. During this process, the supply pump 5 is started to pump the coolant into the liquid inlet 2 through the flow valve 4. The flow valve 4 can adjust the flow rate of the pumped coolant. The coolant enters the condensation outer chamber 11 from the liquid inlet 2, and enters the condensation inner chamber 12 from the condensation outer chamber 11 through the first connecting pipe 14. The coolant flows from bottom to top. During the flow of the coolant, since the condensation outer chamber 11 and the condensation inner chamber 12 are both curved surfaces, the contact area with the steam is large. The coolant can fully absorb the heat of the steam passing through the steam flow chamber 13. The coolant finally passes through the second connecting pipe 15 and flows out from the liquid outlet 3. The cooled liquid finally flows out from the discharge port 17.
