Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a hydrogenation reactor for reducing the sulfur content of dicyclopentadiene. 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 EPDM rubber. Industrially produced dicyclopentadiene is divided into chemical-grade and polymer-grade dicyclopentadiene. However, dicyclopentadiene raw materials usually contain a certain amount of sulfur impurities, which can affect the quality and performance of subsequent products, such as reducing the vulcanization rate of rubber and affecting the stability of resins. Therefore, desulfurization treatment is required before using dicyclopentadiene, necessitating the use of a hydrogenation reactor.

[0003] In existing hydrogenation reactors, dicyclopentadiene feedstock is typically fed into the reactor for desulfurization. However, in actual use, it is not possible to quickly and easily fuse the dicyclopentadiene feedstock with hydrogen, nor is it possible to quickly and easily perform filtration, thus reducing the working efficiency of the hydrogenation reactor.

[0004] Therefore, we urgently need to provide a hydrogenation reactor for reducing the sulfur content of dicyclopentadiene. Utility Model Content

[0005] The purpose of this invention is to provide a hydrogenation reactor for reducing the sulfur content of dicyclopentadiene, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydrogenation reactor for reducing the sulfur content of dicyclopentadiene, comprising a reaction chamber and a support frame, wherein a reaction structure is provided inside the reaction chamber;

[0007] The reaction structure includes a processing mechanism and an auxiliary mechanism;

[0008] The processing mechanism includes a motor, a rotating rod, a stirring blade, a dividing plate, and a gas guide pipe. The output end of the motor is connected to the bottom of the rotating rod, the outer wall of the rotating rod is connected to the inner wall of the stirring blade, the inner wall of the reaction chamber is connected to the outer side of the dividing plate, the top of the dividing plate is connected to one end of the gas guide pipe, a baffle is fixedly installed on the inner wall of the reaction chamber, an installation plate is fixedly installed on the inner wall of the reaction chamber, a filter screen is pressed against the inner side of the installation plate, a limit plate is fixedly installed at the bottom of the filter screen, and a fixing bolt is threadedly connected to the inner wall of the limit plate.

[0009] A further improvement is that the number of stirring blades is four, and the stirring blades are symmetrically distributed on the outer wall of the rotating rod. The number of gas guide pipes is several, and the gas guide pipes are symmetrically distributed on the top of the dividing plate. This allows for quick and convenient mixing of dicyclopentadiene and hydrogen, thereby enabling better desulfurization.

[0010] A further improvement is that the number of baffles is six, which are symmetrically distributed on the inner wall of the reaction chamber, and the number of filters is two, which are symmetrically distributed on the inner side of the mounting plate, thereby enabling quick and convenient filtration of dicyclopentadiene and improving the desulfurization effect.

[0011] A further improvement is that the limiting plate is L-shaped, the bottom of the mounting plate has a limiting hole, and the top of the fixing bolt is threaded to the inner wall of the limiting hole, so that the filter screen can be quickly and easily disassembled and assembled, thereby enabling better filtration.

[0012] A further improvement is that the auxiliary mechanism includes a liquid inlet pipe, a connecting plate, an atomizing nozzle, and a temperature sensor. One end of the liquid inlet pipe is connected to one end of the atomizing nozzle, the top of the atomizing nozzle is connected to the bottom of the connecting plate, and the top of the baffle is connected to the bottom of the temperature sensor.

[0013] A further improvement is that the number of atomizing nozzles is several, and the atomizing nozzles are symmetrically distributed at the bottom of the connecting plate. The number of temperature sensors is six, and the temperature sensors are symmetrically distributed at the top of the six baffles. This enables the dicyclopentadiene to be atomized and sprayed quickly and conveniently, thereby improving the desulfurization process.

[0014] A further improvement is that the outer wall of the reaction chamber is connected to the inner wall of the support frame, the bottom of the reaction chamber is connected to the top of the motor, an air inlet pipe is provided at the bottom of the reaction chamber, and the inner wall of the reaction chamber is connected to the top of the connecting plate.

[0025] 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.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] Example 1:

[0028] A hydrogenation reactor for reducing the sulfur content of dicyclopentadiene includes a reaction chamber 1 and a support frame 2, wherein a reaction structure is provided inside the reaction chamber 1.

[0029] The reaction structure includes a processing mechanism 3 and an auxiliary mechanism 4;

[0030] The processing mechanism 3 includes a motor 301, a rotating rod 302, a stirring blade 303, a dividing plate 304, and a gas guide pipe 305. The output end of the motor 301 is connected to the bottom of the rotating rod 302. The outer wall of the rotating rod 302 is connected to the inner wall of the stirring blade 303. The inner wall of the reaction chamber 1 is connected to the outer side of the dividing plate 304. The top of the dividing plate 304 is connected to one end of the gas guide pipe 305. A baffle plate 306 is fixedly installed on the inner wall of the reaction chamber 1. An installation plate 307 is fixedly installed on the inner wall of the reaction chamber 1. A filter screen 308 is pressed against the inner side of the installation plate 307. A limit plate 309 is fixedly installed at the bottom of the filter screen 308. A fixing bolt 310 is threadedly connected to the inner wall of the limit plate 309.

[0031] In this embodiment, there are four stirring blades 303, which are symmetrically distributed on the outer wall of the rotating rod 302. There are several gas guide pipes 305, which are symmetrically distributed on the top of the dividing plate 304. This allows for quick and convenient mixing of dicyclopentadiene and hydrogen, thereby enabling better desulfurization.

[0032] Furthermore, there are six baffles 306, which are symmetrically distributed on the inner wall of the reaction chamber 1. There are two filter screens 308, which are symmetrically distributed on the inner side of the mounting plate 307. This allows for quick and convenient filtration of dicyclopentadiene, thereby improving the desulfurization effect.

[0033] Furthermore, the limiting plate 309 is L-shaped, and the mounting plate 307 has a limiting hole at the bottom. The top of the fixing bolt 310 is threaded to the inner wall of the limiting hole, so that the filter screen 308 can be quickly and easily disassembled and assembled, thereby enabling better filtration.

[0034] When it is necessary to reduce the sulfur content of dicyclopentadiene, the operator introduces dicyclopentadiene into the reaction chamber 1 through the auxiliary mechanism 4. Hydrogen is then introduced into the reaction chamber 1 through the inlet pipe located at the bottom, and dispersed through the dividing plate 304 and the gas guide pipe 305, thus ensuring uniform mixing of the hydrogen and dicyclopentadiene raw material. At this point, the motor 301 is started, driving the rotating rod 302 to rotate. The rotation of the rotating rod 302, in turn, drives the stirring blade 303 to rotate. The rotation of the stirring blade 303 quickly and easily mixes the hydrogen and dicyclopentadiene raw material, thereby achieving more efficient mixing. To facilitate desulfurization, the installation of baffle 306 reduces the flow rate of dicyclopentadiene and hydrogen, thereby increasing their time within the reaction chamber 1. The filter 308 then quickly and easily filters them, improving the desulfurization effect. To remove the filter 308, rotate the fixing bolt 310 to move it along the inner wall of the limiting plate 309. Moving the fixing bolt 310 allows it to be pulled out from the bottom of the mounting plate 307, enabling removal of the filter 308. Reinstallation is achieved by repeating the above steps.

[0035] Example 2:

[0036] Based on Embodiment 1, the auxiliary mechanism 4 includes an inlet pipe 401, a connecting plate 402, an atomizing nozzle 403, and a temperature sensor 404. One end of the inlet pipe 401 is connected to one end of the atomizing nozzle 403. The top of the atomizing nozzle 403 is connected to the bottom of the connecting plate 402. The top of the baffle 306 is connected to the bottom of the temperature sensor 404.

[0037] In this embodiment, there are several atomizing nozzles 403, which are symmetrically distributed at the bottom of the connecting plate 402. There are six temperature sensors 404, which are symmetrically distributed at the top of the six baffles 306. This enables the dicyclopentadiene to be atomized and sprayed quickly and conveniently, thereby improving the desulfurization process.

[0038] Furthermore, the outer wall of the reaction chamber 1 is connected to the inner wall of the support frame 2, the bottom of the reaction chamber 1 is connected to the top of the motor 301, an air inlet pipe is provided at the bottom of the reaction chamber 1, and the inner wall of the reaction chamber 1 is connected to the top of the connecting plate 402.

[0039] When it is necessary to reduce the sulfur content of dicyclopentadiene, the operator delivers dicyclopentadiene to the atomizing nozzle 403 through the liquid inlet pipe 401. At this time, by activating the atomizing nozzle 403, the dicyclopentadiene is atomized and sprayed out, so that the liquid falls evenly in the form of fine droplets, increasing the contact area between the liquid and hydrogen. By installing multiple temperature sensors 404 at different heights inside the reaction chamber 1, the temperature changes at various locations inside the reaction chamber 1 can be monitored in real time. By monitoring the temperature data, the flow rate of the cooling or heating medium can be adjusted in a timely manner to ensure that the reaction takes place within a suitable temperature range, thereby improving the reaction efficiency and desulfurization effect.
