Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a dicyclopentadiene distillation apparatus. Background Technology

[0002] Dicyclopentadiene (DCPD) is an important component of the C9 fraction produced by ethylene cracking and a dimerization product of cyclopentadiene (CPD) in the C5 fraction. It is mainly used in pharmaceuticals, pesticides, resin products, and as the third monomer in ethylene propylene diene monomer (EPDM) rubber. Industrially produced dicyclopentadiene is divided into chemical-grade and polymer-grade dicyclopentadiene. To provide high-purity dicyclopentadiene for high-end product applications, distillation equipment is required for rectification.

[0003] In existing distillation units, dicyclopentadiene feedstock is usually directly introduced into the distillation unit for distillation. However, in actual use, it is not possible to quickly and conveniently liquefy the dicyclopentadiene feedstock before distillation, and the liquefaction process is slow, which reduces the working efficiency of the distillation unit.

[0004] Therefore, we urgently need to provide a dicyclopentadiene distillation apparatus. Utility Model Content

A second water pump is fixedly installed on the inner wall of the spraying box. One end of the second water pump is connected to a material guide pipe.

[0009] A further improvement is that there are two air inlet pipes, which are symmetrically distributed on the inner wall of the spray box. Several vent holes are opened on one side of each air inlet pipe, so that dicyclopentadiene gas can be quickly and conveniently mixed with water, thereby enabling rapid and convenient cooling and liquefaction.

[0011] A further improvement is that the distillation mechanism includes a support rod, a filter box, a gas guide pipe, an exhaust gas pipe, and a baffle plate. The top of the support rod is connected to the bottom of the filter box, the bottom of the filter box is connected to the top of the gas guide pipe, the top of the distillation box is connected to one end of the exhaust gas pipe, the inner wall of the filter box is connected to one side of the baffle plate, a filter screen is pressed against the inner wall of the baffle plate, a fixing plate is fixedly installed at the bottom of the filter screen, an adjusting box is fixedly installed on the outer wall of the filter box, a limit rod is slidably connected to the inner wall of the adjusting box, and a blocking plate is fixedly installed on the outer wall of the limit rod.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] Example 1:

[0027] A dicyclopentadiene distillation apparatus includes a distillation tank 1 and a spray tank 2, with a distillation structure provided on the outside of the distillation tank 1.

[0028] The distillation structure includes a spraying mechanism 3 and a distillation mechanism 4;

[0029] The spraying mechanism 3 includes an air inlet pipe 301, a motor 302, a rotating rod 303, a stirring rod 304, and a water pump 305. The inner wall of the spray box 2 is connected to the outer wall of the air inlet pipe 301. The output end of the motor 302 is connected to the bottom of the rotating rod 303. The outer wall of the rotating rod 303 is connected to the inner wall of the stirring rod 304. The inner wall of the spray box 2 is connected to one end of the water pump 305. A water guide pipe 306 is connected to one end of the water pump 305. A spray head 307 is connected to one end of the water guide pipe 306. An installation plate 308 is fixedly installed on the top of the spray head 307. A second water pump 309 is fixedly installed on the inner wall of the spray box 2. A material guide pipe 310 is connected to one end of the second water pump 309.

[0030] In this embodiment, there are two air inlet pipes 301, which are symmetrically distributed on the inner wall of the spray box 2. Several ventilation holes are opened on one side of the air inlet pipe 301, so that the dicyclopentadiene gas can be quickly and conveniently mixed with water, thereby enabling the cooling and liquefaction work to be carried out quickly and conveniently.

[0031] Furthermore, there are three stirring rods 304, which are symmetrically distributed on the outer wall of the rotating rod 303. There are several spray heads 307, which are symmetrically distributed at the bottom of the two mounting plates 308, so that water can be sprayed out quickly and conveniently, thereby further cooling the dicyclopentadiene gas.

[0032] Furthermore, a spray box 2 is provided on one side of the distillation tank 1. The bottom of the spray box 2 is connected to the top of the motor 302. One side of the distillation tank 1 is connected to one end of the air inlet pipe 301. The top of the distillation tank 1 is connected to the bottom of the support rod 401.

[0033] When dicyclopentadiene needs to be distilled, since the freshly prepared dicyclopentadiene is in a gaseous state, the operator introduces it into the spray box 2 through the gas inlet pipe 301. At this time, the motor 302 is started, which drives the rotating rod 303 to rotate. The rotation of the rotating rod 303 drives the stirring rod 304 to rotate. The rotation of the stirring rod 304 can stir and mix the dicyclopentadiene gas entering the spray box 2 with the water inside the spray box 2, thereby quickly and conveniently cooling the dicyclopentadiene gas and liquefying it. At this time, the water pump 305 operates to... Water inside the spray box 2 is transported to the spray head 307 through the water pipe 306 and sprayed out through the spray head 307, which can better mix with the dicyclopentadiene gas and further improve the cooling rate of the dicyclopentadiene gas. After the dicyclopentadiene gas is liquefied, the dicyclopentadiene liquid inside the spray box 2 can be quickly and conveniently transported to the distillation tank 1 through the feed pipe 310 by starting the water pump 2 309. By starting the distillation tank 1, the dicyclopentadiene can be distilled, which makes it more convenient for operators to use.

[0034] Example 2:

[0035] Based on Embodiment 1, the distillation mechanism 4 includes a support rod 401, a filter box 402, a gas guide pipe 403, an exhaust gas pipe 404, and a baffle plate 405. The top of the support rod 401 is connected to the bottom of the filter box 402. The bottom of the filter box 402 is connected to the top of the gas guide pipe 403. The top of the distillation box 401 is connected to one end of the exhaust gas pipe 404. The inner wall of the filter box 402 is connected to one side of the baffle plate 405. The inner wall of the baffle plate 405 is in contact with a filter screen 406. A fixing plate 407 is fixedly installed at the bottom of the filter screen 406. An adjusting box 408 is fixedly installed on the outer wall of the filter box 402. A limiting rod 409 is slidably connected to the inner wall of the adjusting box 408. A baffle plate 410 is fixedly installed on the outer wall of the limiting rod 409.

[0036] In this embodiment, there are four baffles 405, which are symmetrically distributed on the inner wall of the filter box 402. There are two filter screens 406, which are symmetrically distributed on the inner wall of the filter box 402. This allows for quick and convenient filtration of dicyclopentadiene, thereby enabling better distillation.

[0037] Furthermore, a limiting hole is provided on one side of the fixing plate 407, and one end of the limiting rod 409 is inserted into the inner wall of the limiting hole. A spring is fixedly installed between one side of the blocking plate 410 and the inner wall of the regulating box 408, so that the filter screen 406 can be quickly and conveniently disassembled and assembled, and thus can be used better.

[0038] When dicyclopentadiene needs to be distilled, since the freshly prepared dicyclopentadiene is in a gaseous state, the operator introduces it into the spray box 2 through the inlet pipe 301. By activating the spray mechanism 3, the dicyclopentadiene gas can be quickly and conveniently liquefied, and the dicyclopentadiene liquid can be transported into the distillation tank 1. By activating the distillation tank 1, the dicyclopentadiene can be distilled. Controlling the temperature can evaporate the water in the dicyclopentadiene liquid, and the water vapor can be discharged through the exhaust pipe 404. Other components in the dicyclopentadiene liquid need to be distilled again at a higher temperature. At this time, the distilled gas is transported to the filter box 402 through the gas guide pipe 403. The baffle 405 can reduce the gas flow in the filter box 402. The internal flow rate increases the time the gas spends inside the filter box 402, filtering impurities from the gas through the filter screen 406 and discharging and recovering the gas through the exhaust pipe at the top of the filter box 402. When the filter screen 406 needs to be removed, the limiting rod 409 is pulled to slide against the inner wall of the regulating box 408. The sliding of the limiting rod 409 moves the baffle plate 410, which in turn compresses the spring and pulls the limiting rod 409 out from the side of the fixing plate 407, thus releasing the limiting fixation of the filter screen 406 and allowing it to be removed from the filter box 402. When installation is required, the above steps are repeated in reverse, thus enabling better distillation.
