Technical Field

[0001] This utility model relates to the field of carbon black reactor technology, and in particular to a device for optimizing airflow distribution inside a carbon black reactor. Background Technology

[0002] Optimizing the airflow distribution within the carbon black reactor is a key step in improving carbon black quality and yield, reducing energy consumption, and minimizing byproducts.

[0003] In the prior art, such as Chinese Patent No. CN206308302U, a reactor device for carbon black production is disclosed. An insulation shell is added to the outside of the reactor body. The cavity between the insulation shell and the outer wall of the reactor body can be filled with water. During the carbon black production process, the heat of the outer shell of the reactor body is absorbed by the water, and this heated water can provide hot water for the factory.

[0004] In the above technical solution, since the contact area between hot crude oil and hot air during the reaction in the reactor is maintained within a certain small gradient range, the types of carbon black products that can be produced are relatively few.

[0005] Based on this, a device for optimizing airflow distribution in a carbon black reactor is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a device for optimizing airflow distribution in a carbon black reactor to solve the problems mentioned in the background art.

[0007] The technical solution of this utility model is: a device for optimizing airflow distribution in a carbon black reactor, comprising a furnace body, and further comprising:

[0008] A fixed half-pipe is fixedly connected to the inner wall of the furnace body. A rotating half-pipe is rotatably connected to one side of the fixed half-pipe. Multiple gas outlet pipes are fixedly connected to the surface of the rotating half-pipe. A flow divider is fixedly connected to the inner wall of the rotating half-pipe.

[0009] A spoiler cylinder has multiple spoiler plates fixedly connected to its surface. One end of the spoiler cylinder is fixedly connected to one side of the flow divider cavity, and the surface of the exhaust pipe is in contact with the surface of the spoiler cylinder.

[0010] In some embodiments, a motor is fixedly installed at one end of the furnace body, and the output end of the motor passes through one end of the furnace body and is fixedly connected to one side of the diversion chamber.

[0011] In some embodiments, one end of the furnace body is fixedly connected to two air inlet pipes, and one end of each of the two air inlet pipes is fixedly connected to the surface of a fixed half-pipe.

[0012] In some embodiments, an annular diverter pipe is fixedly connected to the inner wall of the furnace body, and a plurality of oil nozzles are fixedly connected to the surface of the annular diverter pipe. An oil inlet pipe is fixedly connected to the surface of the furnace body, and one end of the oil inlet pipe is fixedly connected to the surface of the annular diverter pipe.

[0013] In some embodiments, the surface of the furnace body is fixedly connected to two water inlets and two water outlets, which are symmetrically fixedly connected to the surface of the furnace body.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] This invention utilizes a diversion chamber to disperse air, thereby increasing the contact area between the incoming air and the hot crude oil, thus improving the airflow distribution effect. The combination of a baffle tube, baffle plates, and multiple outlet pipes arranged in a ring array ensures that the incoming air is evenly pushed forward, mixing with the crude oil sprayed from the nozzle. Furthermore, the rotating baffle tube and baffle plates generate a rotating airflow, further enhancing the contact and mixing effect between the air and the hot crude oil, thereby improving the carbon black reaction efficiency inside the furnace.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved airflow distribution optimization device within a carbon black reactor. The technical solution of this utility model is as follows:

[0024] like Figures 1-3 As shown, the airflow distribution optimization device inside the carbon black reactor includes a furnace body 1, and also includes:

[0025] A fixed half-pipe 4 is fixedly connected to the inner wall of the furnace body 1. A rotating half-pipe 13 is rotatably connected to one side of the fixed half-pipe 4. Multiple air outlet pipes 14 are fixedly connected to the surface of the rotating half-pipe 13. A flow divider 6 is fixedly connected to the inner wall of the rotating half-pipe 13. Through the rotatable connection between the fixed half-pipe 4 and the rotating half-pipe 13, the motor 3 can drive the flow divider 6 and the turbulence cylinder 7 to rotate without affecting the air intake or causing motion interference. Multiple air outlet pipes 14 are arranged in a ring array on the surface of the rotating half-pipe 13.

[0026] The spoiler 7 has multiple spoiler vanes 8 fixedly connected to its surface. One end of the spoiler 7 is fixedly connected to one side of the diversion cavity 6. The surface of the air outlet pipe 14 is in contact with the surface of the spoiler 7. The rotating spoiler 7 and spoiler vanes 8 can drive the air to generate a rotating airflow, thereby improving the contact and mixing effect between the air and the hot crude oil.

[0027] like Figure 2 and Figure 3 As shown, in one embodiment, a motor 3 is fixedly installed at one end of the furnace body 1. The output end of the motor 3 passes through one end of the furnace body 1 and is fixedly connected to one side of the diversion cavity 6. The motor 3 can drive the diversion cavity 6 and the rotating half-pipe 13 to rotate, thereby realizing the rotation of the turbulence tube 7 and improving the airflow distribution effect.

[0028] Two air inlet pipes 5 are fixedly connected to one end of the furnace body 1, and one end of each air inlet pipe 5 is fixedly connected to the surface of the fixed half-pipe 4.

[0029] An annular manifold 10 is fixedly connected to the inner wall of the furnace body 1. Multiple oil nozzles 11 are fixedly connected to the surface of the annular manifold 10. An oil inlet pipe 9 is fixedly connected to the surface of the furnace body 1. One end of the oil inlet pipe 9 is fixedly connected to the surface of the annular manifold 10.

[0030] like Figure 1 and Figure 2As shown, in one embodiment, the surface of the furnace body 1 is fixedly connected to two water inlets 2 and two water outlets 12, respectively. The two water inlets 2 and two water outlets 12 are symmetrically fixedly connected to the surface of the furnace body 1. The inner wall of the furnace body 1 is provided with a heat insulation layer, and water can be added through the water inlets 2. The heat insulation layer provides heat insulation for the inside of the furnace body 1, and the waste heat generated during the carbon black production inside the furnace body 1 can heat the cold water injected through the water inlets 2, and finally turn it into hot water and discharge it through the water outlets 12, so that the heat generated during the carbon black production reaction can be partially recovered and utilized.

[0031] The specific working method is as follows: During the carbon black reaction production process, air is injected into the furnace body 1 through the air inlet pipe 5. The air in the air inlet pipe 5 can pass through the distribution chamber 6 and the fixed half pipe 4 and the rotating half pipe 13, and then be sprayed out from the through hole on the distribution chamber 6 and the air outlet pipe 14 on the rotating half pipe 13. The distribution chamber 6 can disperse the air, thereby increasing the contact area between the incoming air and the hot crude oil, thus improving the airflow distribution effect. Through the cooperation of the set baffle cylinder 7, baffle plate 8 and multiple air outlet pipes 14 distributed in a ring array, the incoming air can be pushed evenly, thereby mixing with the crude oil sprayed from the oil nozzle 11. The rotating baffle cylinder 7 and baffle plate 8 can drive the air to generate a rotating airflow, thereby improving the contact and mixing effect between the air and the hot crude oil, thereby improving the carbon black reaction efficiency inside the furnace body 1.

[0032] Crude oil is supplied to the annular splitter pipe 10 through the oil inlet pipe 9. The crude oil inside the annular splitter pipe 10 is atomized and diffused from the oil injector 11 under pressure. The atomized and diffused crude oil inside the furnace body 1 mixes with the hot air injected through the air inlet pipe 5 to carry out the carbon black production reaction.
