Description

Technical Field

[0001] This invention relates to the field of carbon black production technology, and in particular to a novel carbon black axial reaction oil gun device. Background Technology

[0002] In high-temperature reaction processes such as carbon black production, the axial reaction oil gun serves as a crucial fuel supply device, and its atomization performance directly affects combustion efficiency, reaction stability, and pollutant emission levels. Currently, most widely used oil guns employ a traditional circular nozzle structure, achieving fuel atomization through high pressure or air assistance. However, this structure has significant limitations and struggles to meet the requirements of modern processes for high-efficiency combustion and low emissions.

[0003] Traditional fuel injectors have a relatively simple nozzle design, typically a single circular outlet. This results in poor uniformity of fuel distribution, with large and unevenly distributed droplets, affecting subsequent mixing with air. To compensate for incomplete combustion due to poor atomization, it is often necessary to increase the oxygen supply and introduce a large amount of excess air to ensure the fuel burns as completely as possible. However, this not only wastes energy and increases heat loss carried away by flue gas, but also significantly increases the formation of nitrogen oxides (NOx), exacerbating environmental pollution. Furthermore, because the fuel flow at the nozzle is relatively stable and lacks an effective disturbance mechanism, localized fuel-rich zones can easily form near the nozzle, further reducing combustion efficiency and potentially causing coking and clogging, affecting the continuous operation and maintenance frequency of the fuel injector. Especially in carbon black production processes, the high reaction temperatures and complex operating conditions place higher demands on the atomization stability, anti-coking properties, and high-temperature resistance of the fuel injector. Existing technologies still have significant shortcomings in these aspects, hindering the optimization and improvement of the overall reaction system.

[0004] Therefore, it is urgent to innovate and improve the structure of the oil gun atomizing nozzle. By optimizing the nozzle shape and internal flow channel design, the dispersion and uniformity of oil spray can be enhanced, thereby reducing the dependence on excess oxygen, improving combustion efficiency while reducing pollutant emissions, and enhancing the reliability and economy of equipment operation. Summary of the Invention

[0005] The purpose of this invention is to provide a novel carbon black axial reaction oil gun device to improve the problems existing in the prior art.

[0006] This invention is implemented as follows: A novel carbon black axial reaction oil gun device is provided, comprising an axial oil channel, a mechanical atomizing nozzle, a compressed air inlet valve, an axial gas direct injection channel, and an axial circulating water channel. One end of the axial oil channel is connected to the mechanical atomizing nozzle. A compressed air inlet valve is located on the side of the axial oil channel away from the mechanical atomizing nozzle. An axial gas direct injection channel is sleeved outside the axial oil channel, and an axial circulating water channel is sleeved outside the axial gas direct injection channel. The mechanical atomizing nozzle is provided with uniformly distributed nozzles, each nozzle being frustoconical in shape.

[0007] More preferably, the nozzle is provided with a protrusion for blocking the liquid ejected from the nozzle.

[0008] More preferably, the side of the nozzle closest to the inner wall of the mechanical atomizing nozzle is the feed side, and the side closest to the outer wall of the mechanical atomizing nozzle is the discharge side, wherein the diameter of the nozzle feed side is smaller than the diameter of the discharge side.

[0009] More preferably, the atomization pressure of the mechanical atomizing nozzle is 0.8-1.2 MPa.

[0010] More preferably, the mechanical atomizing nozzle has eight nozzles.

[0011] More preferably, the axial oil channel, the mechanical atomizing nozzle, the compressed air inlet valve, the axial gas direct injection channel, and the axial circulating water channel are all made of high-temperature resistant alloy steel.

[0012] Compared with existing technologies, the present invention has the following advantages: By setting a larger outlet diameter for the nozzle, the present invention allows the fuel to spread more widely during spraying, forming a wider spray angle. This helps fuel particles mix with air over a larger area, thereby improving atomization quality. Introducing compressed air into the axial oil channel through the compressed air inlet valve significantly improves fuel atomization quality. After the compressed air mixes with the fuel, finer and more uniformly distributed droplets are formed at the nozzle's outlet side. This improvement helps increase the contact area between the fuel droplets and oxygen, promoting more complete combustion. Furthermore, the protrusions inside the nozzle allow for irregular fuel spraying, and the introduction of compressed air further enhances this irregularity, ensuring that the fuel is more evenly dispersed throughout the combustion space, avoiding localized rich or poor fuel distribution. Simultaneously, appropriate airflow helps remove residual fuel near the nozzle, reducing the risk of blockage due to prolonged operation. The scouring effect of the airflow on the nozzle's interior also helps reduce the possibility of coking, extending the equipment's service life. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, 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 scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, but does not exclude other elements or objects.

[0017] Example 1: This invention provides a novel carbon black axial reaction oil gun device, comprising an axial oil channel 1, a mechanical atomizing nozzle 2, a compressed air inlet valve 3, an axial gas direct injection channel 4, and an axial circulating water channel 5. The mechanical atomizing nozzle 2 is connected to the right end of the axial oil channel 1, the compressed air inlet valve 3 is provided on the left side of the axial oil channel 1, the axial gas direct injection channel 4 is sleeved on the outside of the axial oil channel 1, and the axial circulating water channel 5 is sleeved on the outside of the axial gas direct injection channel 4. The mechanical atomizing nozzle 2 is provided with uniformly distributed nozzles 6, and the nozzles 6 are frustoconical in shape.

[0018] Furthermore, a protrusion 7 is provided inside the nozzle 6 to block the liquid sprayed from the nozzle 6. The side of the nozzle 6 near the inner wall of the mechanical atomizing nozzle 2 is the feed side, and the side near the outer wall of the mechanical atomizing nozzle 2 is the discharge side. The diameter of the feed side of the nozzle 6 is smaller than the diameter of the discharge side. The larger outlet diameter allows the oil to spread more widely when sprayed, forming a wider spray angle, which helps the oil particles mix with the air over a larger range, thereby improving the atomization quality.

[0019] Specifically, by introducing compressed air into the axial oil channel 1 through the compressed air inlet valve 3, the atomization quality of the oil can be significantly improved. After the compressed air mixes with the oil, it forms finer and more uniformly distributed droplets at the discharge side of the nozzle 6. This improvement helps to increase the contact area between the oil droplets and oxygen, promoting more complete combustion. Furthermore, the protrusion 7 inside the nozzle 6 allows the oil to be sprayed out irregularly, and the introduction of compressed air can further enhance this irregularity, ensuring that the oil is more evenly dispersed throughout the combustion space, avoiding localized oil richness or leanness. At the same time, appropriate airflow can help remove residual oil near the nozzle, reducing the risk of blockage caused by long-term operation. The scouring effect of the airflow on the inside of the nozzle also helps to reduce the possibility of coking and extend the service life of the equipment.

[0020] In one embodiment, the atomization pressure of the mechanical atomizing nozzle 2 is 0.8-1.2 MPa.

[0021] In one embodiment, the mechanical atomizing nozzle 2 has eight nozzles 6.

[0022] In one embodiment, the axial oil channel 1, the mechanical atomizing nozzle 2, the compressed air inlet valve 3, the axial gas direct injection channel 4, and the axial circulating water channel 5 are all made of high-temperature resistant alloy steel.

However, it should be understood that such modifications and variations fall within the scope and spirit of the invention as defined in the claims.
