Technical Field

[0001] The present invention relates to the technical field of chemical production, in particular to an o-phenylphenol production device. Background Art

[0002] o-Phenylbenzene, also known as 2-phenylphenol, is an organic compound with the chemical formula C12H10O. It is a white, light yellow or light red crystalline powder with a faint phenolic odor. It is insoluble in water but soluble in ethanol, acetone, isopropanol, ether, benzene and alkaline solutions. o-Phenylphenol is an organic chemical product with a wide range of uses. It is widely used in sterilization and antiseptics, printing and dyeing auxiliaries and surfactants, and in the synthesis of new plastics, stabilizers for resins and polymer materials, as well as flame retardants.

[0003] o-phenylphenol is mainly made from cyclohexanone, which is condensed and dehydrated to obtain the dimer - cyclohexenylcyclohexanone, which is then catalytically dehydrogenated and refined to obtain o-phenylphenol.

The process consists of mixing, pre-cooling, cooling crystallization, centrifugal separation, drying and other processes.

Under the reaction force after the elastic deformation of the return spring 23, the partition plate 5 is in a vibrating state, and the elastic carbon fiber rod 13 will swing slightly, thereby improving the contact effect between the elastic carbon fiber rod 13 and the volatilized petroleum ether in the reactor body 3, accelerating the condensation, liquefaction and reflux dripping of the volatilized petroleum ether, and facilitating the liquefied petroleum ether to be thrown off from the elastic carbon fiber rod 13 and the return liquid protrusion 14.

[0032] Furthermore, if Figure 6 and Figure 7As shown, the temperature control component includes a spiral heating tube 24 and a heat exchanger 25. The spiral heating tube 24 is located inside the temperature control chamber 4, and the heat exchanger 25 is located below the semiconductor refrigeration plate 10. A rectangular groove is provided on the heat exchanger 25, and the heat dissipation port 17 is connected to the inner wall of the rectangular groove by bolts; an air intake cavity and an exhaust cavity are provided inside the heat exchanger 25, and an exhaust seat 28 is provided on the heat exchanger 25. The exhaust seat 28 is connected to the exhaust cavity by bolts, the heat dissipation port 17 is located in the air intake cavity, and the inner wall of the air intake cavity is connected by bolts. Two symmetrical air inlet pipes 26 are bolted together, and the other end of the air inlet pipe 26 is bolted to the upper tube of the spiral heating tube 24. The inner wall of the exhaust chamber is bolted to three equidistant exhaust pipes 27, and the other end of the exhaust pipe 27 is bolted to the lower tube of the spiral heating tube 24. During the transportation of the heated gas in the spiral heating tube 24, the heat-conducting liquid (oil) in the temperature-control chamber 4 is heated, thereby increasing its temperature and thus increasing the temperature of the reactor body 3, thereby achieving the effect of promoting the mixed reaction of crude o-phenylphenol and petroleum ether.

[0033] Furthermore, Figure 1 and Figure 8 As shown, the stirring assembly includes a shaft 29 and three stirring crank rods 30. The shaft 29 is connected to the rotating shaft 9 by bolts, and the three stirring crank rods 30 are located at the bottom end of the shaft 29 and are equidistantly distributed around the circumference. The three stirring crank rods 30 are connected to the shaft 29 by bolts; the three stirring crank rods 30 are connected to the shaft 29 by bolts; the three stirring crank rods 30 are connected to the inner support plate 31 by bolts, and the upper outer wall of the inner support plate 31 is connected to a plurality of equidistant elastic rods 32 by bolts, and the top ends of the plurality of elastic rods 32 are connected to spherical heads 33 by bolts. The elastic rods 32 shake slightly due to the centrifugal force and the pressure exerted by the internal liquid, so that the elastic rods 32 and the spherical heads 33 improve the contact effect with the internal liquid, thereby promoting the mixing between the crude o-phenylphenol and petroleum ether.

[0034] Furthermore, Figure 2 As shown, circular holes of different sizes are provided on both sides of the reactor body 3. The inner wall of the large circular hole is connected to a feeding pipe 34 by bolts, and the inner wall of the small circular hole is connected to a petroleum ether adding pipe 35 by bolts. A discharge port is provided at the bottom of the reactor body 3, and the inner wall of the discharge port is connected to a discharge pipe 36 by bolts. The other end of the discharge pipe 36 passes through the bottom wall of the outer cylinder 1, and a valve is provided on the discharge pipe 36.

[0035] Working Principle: After the device is powered on, crude o-phenylphenol is added to the reactor body 3 from the feeding pipe 34, and then an appropriate amount of petroleum ether is added from the petroleum ether adding pipe 35. The motor 7 drives the rotating shaft 9 to rotate, and the shaft 29 drives the stirring crank 30 to stir and mix the crude o-phenylphenol and petroleum ether. During the stirring process, as the stirring crank 30 rotates, the elastic rod 32 shakes slightly due to the centrifugal force and the pressure exerted by the internal liquid. This improves the contact effect between the elastic rod 32 and the spherical head 33 with the internal liquid, promoting the mixing of the crude o-phenylphenol and petroleum ether.

[0036] At the same time, the semiconductor refrigeration sheet 10 is in the power-on working state. The cold gel in the condenser tube 12 circulates in the condenser tube 12 and the refrigeration tube 18 under the action of the pressure pump 21. In the refrigeration tube 18, the cold gel will directly contact the refrigeration port 16, and the cold gel will be absorbed by the heat, so that the overall temperature of the condenser tube 12 drops. The condenser tube 12 contacts the graphene heat conducting plate 11, and the overall temperature of the graphene heat conducting plate 11 drops. The temperature of the elastic carbon fiber rod 13 drops, and the petroleum ether volatilized in the reactor body 3 and the elastic carbon fiber rod 13 are heated. After contact, it will condense into liquid and reflux and drip into the liquid in the reactor body 3. The stirring process of the rotating shaft 9 will exert force on the partition plate 5. Under the reaction force after the elastic deformation of the return spring 23, the partition plate 5 is in a vibrating state, and the elastic carbon fiber rod 13 will swing slightly, thereby improving the contact effect between the elastic carbon fiber rod 13 and the volatilized petroleum ether in the reactor body 3, accelerating the condensation and liquefaction of the volatilized petroleum ether and reflux dripping, and at the same time facilitating the liquefied petroleum ether to be thrown off from the elastic carbon fiber rod 13 and the liquid return protrusion 14;

[0037] The heat dissipation port 17 on the semiconductor refrigeration plate 10 heats the gas in the air inlet cavity of the heat exchanger 25, and after being transported through the spiral heating tube 24, it undergoes secondary circulation from the exhaust cavity, and part of the gas is discharged from the exhaust seat 28. During the transportation of the heated gas in the spiral heating tube 24, it heats the heat transfer fluid (oil) in the temperature control cavity 4, thereby increasing its temperature and thus increasing the temperature of the reactor body 3, thereby promoting the mixed reaction of crude o-phenylphenol and petroleum ether. At the same time, the gas temperature in the spiral heating tube 24 is controlled by adjusting the exhaust efficiency of the exhaust seat 28. When the temperature of the reactor body 3 is high, the exhaust effect of the exhaust seat 28 is improved, and the amount of gas in the secondary circulation in the spiral heating tube 24 is reduced. Conversely, the exhaust effect of the exhaust seat 28 is reduced, and the amount of gas in the secondary circulation is increased.

[0038] During the mixing of crude o-phenylphenol and petroleum ether, the air pressure in the reactor body 3 is regulated by the airflow exchange tube 6. The airflow exchange tube 6 is connected to an external air pump to keep the reactor body 3 in a low-pressure state. On the one hand, this improves the mixing reaction effect between the crude o-phenylphenol and petroleum ether, and on the other hand, reduces the volatilization of petroleum ether and promotes the condensation and liquefaction of petroleum ether.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
