Description

Technical Field

[0001] The present invention relates to a carbon black reactor, and more specifically, to a carbon black reactor with a cooling function, which generates carbon black by inducing a chemical reaction at a high temperature through continuous cooling, so that the diameter of a combustion port arranged inside the reactor does not change. Background Art

[0002] Carbon black is widely used in a variety of applications, including inks, coatings, reinforcing fillers, conductive materials, cathode materials for secondary batteries, electromagnetic shielding materials, and heating components. Due to its excellent physical and chemical properties, including conductivity, chemical resistance, weather resistance, and heat resistance, carbon black is manufactured in pellet or powder form along with various ceramic materials and used as an additive in various products.

[0003] Therefore, producing a uniformly dispersed carbon black product is an important factor in casting processes such as slip-casting, tape-casting, injection molding and die casting.

[0004] Carbon black can be produced through furnace process, channel process, thermal process, acetylene process, etc. Among them, the furnace process is widely used because it can produce carbon black more efficiently.

[0005] In the furnace process, such as Figure 1 As shown, liquid or gaseous combustion oil is supplied together with air through a nozzle into a heating furnace 10 heated at high temperature, where it reacts with an oxidant to generate high-temperature combustion gas. The generated combustion gas passes through a reactor 20 into which raw oil (such as high-viscosity bunker C oil) is injected through an injection nozzle 21. The generated combustion gas chemically reacts with the raw oil at a high temperature (above 1500 degrees Celsius), causing incomplete combustion, thermal decomposition, or dehydrogenation reaction, thereby generating a mixed gas containing carbon black. The generated mixed gas is then processed into a predetermined shape such as pellets or beads through a general capture process and molding process as a subsequent process and is commercialized.

[0006] At this time, the reaction furnace 20 forms a high-temperature environment due to the combustion of the combustion gas and the raw material oil, and the moving speed increases, so a refractory material 23 having high heat resistance must be used inside.

[0007] like Figure 2 As shown, the refractory material 23 is disposed inside the reactor while maintaining a predetermined thickness, and a circular combustion port 25 is formed in the center thereof. The supplied raw material oil and combustion gas are burned in the combustion port 25 .

[0008] However, even if the refractory material 23 has high heat resistance, since the burner 25 continuously maintains a high temperature environment, the inner diameter of the burner 25 of the refractory material 23 will gradually melt within a usage period of about 3-4 months, resulting in changes in the inner diameter shape, so the reactor 20 needs to be replaced regularly.

[0009] If the operation is continued in a state where the inner diameter of the burner 25 changes, a fatal problem will arise in which the production volume based on the preset data value of the burner changes and the quality of the carbon black is deteriorated.

[0010] In addition, since the material of the refractory material is made of a Class I carcinogen, there are also environmental problems when it is discarded.

[0014] (Patent Document 2) Korean Patent No. 10-0602542 Summary of the Invention

[0015] (1) Technical issues to be resolved

[0016] The present invention is proposed to solve the above-mentioned problems and technical prejudices. The purpose of the present invention is to provide a carbon black reactor with a cooling function. The burner of the reactor is made of metal material, and the coolant is continuously circulated in the burner heated to a high temperature to prevent the burner diameter from changing by cooling the entire burner.

[0017] (2) Technical solution

[0018] In order to achieve the above-mentioned purpose, the carbon black reactor with cooling function of the present invention includes: a main body, which is made of a metal material, has a pair of flanges set apart, and has a burner connecting the separated flanges, the center part of the burner is formed through, and the combustion gas and raw oil react in the center part; a plurality of injection nozzles, which inject raw oil into the inside of the burner; a pair of cooling chambers, which are respectively arranged on the inner plate surfaces of the flanges facing each other, so as to diffuse the coolant to the entire surface of the flange while performing heat exchange on the flange; a distribution cooling pipe, which surrounds the outer peripheral surface of the burner in a separated manner to form a flow channel, and is divided into a first supply flow channel and a second supply flow channel by a partition, so that the supplied coolant performs heat exchange on the entire burner while flowing to each of the cooling chambers; a pair of coolant supply pipes, which are respectively installed in the first supply flow channel and the second supply flow channel, and supply coolant; and a coolant discharge pipe, which is respectively installed in the pair of cooling chambers, and discharges the coolant after heat exchange.

[0019] At this time, preferably, the cooling chamber includes: a cooling shell, which is circular and is arranged on the inner plate surface of the flange while passing through the distribution cooling pipe, and forms a cooling space so that the coolant flows from the distribution cooling pipe into the cooling space to perform heat exchange on the flange; and a spiral guide, which is arranged inside the cooling shell and forms a flow channel so that the coolant flowing in from the distribution cooling pipe diffuses spirally toward the outer side of the flange plate surface.

[0020] In addition, preferably, inflow holes communicating with the cooling chambers are respectively formed at both ends of the distribution cooling pipe, so that the coolant supplied to the first supply flow channel and the second supply flow channel respectively flows into each cooling chamber.

[0021] In addition, preferably, an annular clustering baffle is provided on each inner side of the first supply flow channel and the second supply flow channel of the distribution cooling pipe. When the clustering baffle is fixed to the distribution cooling pipe, it forms a gap separated from the outer peripheral surface of the burner port at an inclination in the range of 25 degrees to 35 degrees, so that the flow of coolant passing through the gap is concentrated at the end parts on both sides of the burner port.

[0022] In addition, preferably, a recessed end is formed on the flange plate surface where the cooling chamber is provided, and the recessed end delays the flow time of the coolant so that the heat exchange of the coolant flowing in the cooling chamber is concentrated around the terminal end of the burner.

[0023] On the other hand, preferably, the injection nozzle is coupled to a plurality of injection brackets that pass through the distribution cooling pipe in a state of being radially disposed at the burner.

[0024] In addition, preferably, a cutout portion made of a heat-resistant metal material is further provided around the diameter of the terminal portion on one side of the burner port to prevent carbonization of the diameter edge of the burner port.

[0025] Finally, preferably, a plurality of supporting members are radially arranged between the pair of flanges to maintain the flanges in a spaced-apart state.

[0026] (3) Beneficial effects

[0027] According to the carbon black reactor with cooling function of the present invention having the above-mentioned structure, the burner port of the carbon black reactor is made of heat-resistant metal material, and the cooling efficiency of the burner port heated to a high temperature is improved by supplying coolant in both directions. The supplied coolant flows through the burner port in an air accumulation state and cools the burner port, thereby having an excellent effect of fundamentally preventing the change in the burner port diameter due to continuous exposure to high temperature as in the prior art.

[0028] In particular, the structural effect of concentrating the flowing coolant at the fragile portion around the diameter of the burner tip, thereby further enhancing the stability of the fragile portion, is also very outstanding.

[0029] In addition, since the shape of the combustion port of the carbon black reactor is maintained, the quality of the produced carbon black can be kept stable, and more importantly, no refractory waste is generated as before. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 7 It is along Figure 5 This is a main cross-sectional view taken along line II-II, with the cooling housing without the cooling chamber.

[0040] like Figures 3 to 7 As shown, the carbon black reactor 100 of the present invention includes: a main body 110, which is made of a metal material and has a pair of flanges 111 set apart and a burner 113 connected to the separated flanges 111, and the center of the burner 113 is formed through, and the combustion gas and the raw oil react in the center; a plurality of injection nozzles 120, which inject the raw oil into the burner 113; a pair of cooling chambers 130, which are respectively provided on the inner side plates of the flanges 111 facing each other, so as to diffuse the coolant to the entire surface of the flange 111 while cooling the flange 111. Heat exchange; a distribution cooling pipe 140, which surrounds the outer peripheral surface of the burner 113 in a separated manner to form a flow channel, and is divided into a first supply flow channel 142 and a second supply flow channel 143 by a partition 141, so that the supplied coolant performs heat exchange on the entire burner 113 while flowing to each of the cooling chambers 130; a pair of coolant supply pipes 150, which are respectively installed in the first supply flow channel 142 and the second supply flow channel 143, and supply coolant; and a coolant discharge pipe 160, which is respectively installed in the pair of cooling chambers 130, and discharges the coolant after heat exchange.

[0041] Before explaining, the most significant feature of the carbon black reactor 100 of the present invention is that the burner 113 of the reactor for generating a mixed gas containing carbon black by the reaction of combustion gas and crude oil is made of a metal material, and a structure for cooling the burner 113 that is continuously exposed to a high-temperature environment is provided in the reactor, thereby preventing the diameter of the burner 113 from changing.

[0042] In addition, structures forming the carbon black reaction furnace 100 to be described later are made of a heat-resistant metal material, and the respective structures are set by welding.

[0043] In addition, a pair of components having the same structure are given the same reference numerals, and in order to avoid confusion in the description, only a single structure is described.

[0044] like Figure 3 As shown, the carbon black reaction furnace 100 of the present invention is combined with the heating furnace 10 on the left side of the figure, in which liquid or gas combustion oil and air supplied together from a system pipeline for producing carbon black react with an oxidant to generate high-temperature combustion gas.

[0045] A separate conveying pipe is installed on the right side of the carbon black reactor 100 in the figure, so that the mixed gas containing carbon black generated by the reaction of combustion gas and raw oil in the carbon black reactor 100 can be transported to the subsequent process. The subsequent process of the mixed gas is a routine matter, so the description is omitted.

[0046] In the main body 110 , the combustion gas flowing from the heating furnace 10 and the supplied raw oil react, and thus the main body includes a pair of flanges 111 and a burner 113 made of a metal material.

[0047] like Figure 4 and Figure 5 As shown, the pair of flanges 111 are in the shape of disks having a predetermined thickness and are spaced apart by a predetermined distance in a direction facing each other.

[0048] The burner port 113 is cylindrical in shape, connecting the separated flanges 111 so that the pair of flanges 111 form an integrated shape. The center portion of the burner port 113 is formed in a circular shape along the length direction so that the combustion gas flowing in from the heating furnace 10 reacts with the raw oil supplied through the injection nozzle 120 described below.

[0049] Here, the pair of flanges 111 and the burner 113 are made of different heat-resistant metal materials. The burner 113 is preferably made of SUS316 with reduced carbon content so as to be able to withstand high temperature (above 1500 degrees) environment, while the pair of flanges 111 are preferably made of SUS304 with chromium, nickel and manganese added to iron.

[0050] And, as Figure 5 As shown, a pair of flanges 111 and a burner port 113 are formed into a single body 110 shape by welding.

[0051] Furthermore, a plurality of coupling holes 111 b are formed on the outer peripheral portion of the flange 111 , through which unillustrated bolts for coupling the adjacent pipes and the flange 111 pass.

[0052] In this embodiment, the materials of the burner 113 and the flange 111 are only examples, and there is no limitation on the materials as long as they are metals that can withstand high temperature environments.

[0053] On the other hand, Figure 5 As shown, a cutout portion 114 of a heat-resistant metal material can be further provided around the diameter of the end portion on one side of the burner port 113 (the direction of exhaust of the mixed gas - the right side in the figure) to prevent carbonization of the diameter edge of the burner port 113 due to the high temperature generated by the reaction of the combustion gas and the crude oil.

[0054] At this time, the cutout portion 114 is preferably made of duplex steel 2207 which is a heat-resistant metal material, and is fixed to the diameter edge of the burner port 113 by welding.

[0055] The injection nozzle 120 is used to inject the raw oil (high viscosity bunker oil (Bunker C oil)) directly into the burner 113, so that the combustion gas flowing into the burner 113 can react with the raw oil, such as Figures 4 to 7 As shown, four injection nozzles 120 are radially arranged along the diameter of the burner 113.

[0056] At this time, the injection nozzle 120 is respectively coupled to four injection brackets 121, and the four injection brackets 121 are radially coupled to the burner 113 along the diameter of the burner 113 while passing through the distribution cooling pipe 140 to be described later, and the injection nozzle 120 is connected to the supply line pipe of the raw oil supply tank not shown.

[0057] Here, the injection bracket 121 is installed to pass through the distribution cooling pipe 140 , with the purpose of supporting the injection bracket 121 coupled to the burner 113 while ensuring stable support of the injection nozzle 120 coupled to the injection bracket 121 .

[0058] In addition, the injection nozzle 120 is connected to a raw oil supply tank (not shown), and injects the raw oil into the interior of the burner 113 by supply pressure.

[0059] In this embodiment, four injection nozzles 120 are shown to be installed, but the number can be changed according to the diameter of the burner 113, so the number is not limited.

[0060] The cooling chamber 130 is used to diffuse the coolant flowing in through the distribution cooling pipe 140 to be described later to the entire surface of the flange 111 to perform heat exchange (cooling) on ​​the flange 111. The cooling chamber 130 is composed of a pair and is arranged on the inner plate surfaces of the pair of flanges 111 facing each other.

[0061] Specifically, the cooling chamber 130 serves to allow the coolant supplied to the distribution cooling pipe 140 and primarily cooling the burner 113 to secondarily cool the entire surface of the flange 111 while flowing toward the coolant discharge pipe 160 to be described later.

[0062] Here, as Figures 4 to 7 As shown, the pair of cooling chambers 130 may have the same structure, and thus only a single cooling chamber 130 will be described, and the cooling chamber 130 includes a cooling housing 131 and a spiral guide 133 .

[0063] like Figure 5 As shown, the cooling shell 131 is provided on inner side plate surfaces of the flange 111 facing each other in a circular shape corresponding to the flange 111 in a state of passing through a distribution cooling pipe 140 to be described later.

[0064] At this time, the cooling housing 131 maintains a predetermined height to form a cooling space into which the coolant flows from the distribution cooling pipe 140 to perform heat exchange on the entire surface of the flange 111 , and a spiral guide 133 to be described later may be provided.

[0065] like Figure 6 and Figure 7 As shown, the spiral guide 133 maintains a vortex shape having a predetermined height, thereby forming a flow path through which the coolant flowing into the cooling housing 131 can flow.

[0066] Specifically, the spiral guide 133 is arranged inside the cooling shell 131 and forms a spiral flow channel so that the coolant that has undergone heat exchange with the burner 113 and flows in through the distribution cooling pipe 140 diffuses spirally from the center of the flange 111 to the outside of the plate surface and performs heat exchange on the entire surface of the flange 111.

[0067] Therefore, the spiral guide 133 increases the heat exchange contact area by forming a long coolant flow path, while allowing the coolant to flow quickly through the spiral flow path.

[0068] If the spiral guide 133 is not present, the coolant around the coolant discharge pipe 160 to be described later can be discharged quickly, but the coolant discharge at a location farther away from the coolant discharge pipe 160 will be slower, resulting in different temperature distributions of the coolant flowing inside the cooling chamber 130, and thus uneven heat exchange.

[0069] On the other hand, Figure 5As shown, a circular recessed end 111a recessed at a predetermined height and a predetermined width with the burner port 113 as the center can be formed on the plate surface of the flange 111 covered by the cooling shell 131 of the cooling chamber 130, so that the heat exchange of the coolant flowing along the spiral guide 133 of the cooling chamber 130 is concentrated around the terminal end of the burner port 113.

[0070] like Figure 5 As shown, the recessed end 111a can expand the flow channel through which the coolant can flow deeper and wider, and at least delay the flow time of the coolant flowing through the spiral guide 133 in the recessed end 111a, so that heat exchange can be concentrated around the terminal end of the burner 113.

[0071] In addition, if Figure 5 As shown, the spiral guide 133 forming the portion of the recessed end 111 a may extend to the recessed end 111 a.

[0072] The distribution cooling pipe 140 is used to allow the coolant supplied through the coolant supply pipe 150 to be described later to perform heat exchange with the entire burner 113 while flowing to the respective cooling chambers 130 provided in the pair of flanges 111 .

[0073] For this reason, Figures 4 to 7 As shown, the distribution cooling pipe 140 is in a cylindrical shape with a predetermined length, and its two ends are fixed to the inner surfaces of a pair of flanges 111 in a state of being spaced apart around the outer peripheral surface of the burner 113, thereby forming a flow channel for the coolant to flow between the distribution cooling pipe 140 and the outer peripheral surface of the burner 113.

[0074] The flow channel between the distribution cooling pipe 140 and the outer peripheral surface of the burner 113 is divided into a first supply flow channel 142 and a second supply flow channel 143 by a partition 141 arranged at the center of the longitudinal direction of the distribution cooling pipe 140, so that the supplied coolant can flow simultaneously to each cooling chamber 130 arranged in a pair of flanges 111.

[0075] In addition, if Figures 5 to 7 As shown, inflow holes 140 a communicating with the cooling chamber 130 are formed at both ends of the distribution cooling pipe 140 , so that the coolant supplied to the first supply channel 142 and the second supply channel 143 respectively flows into the cooling chambers 130 provided on the two flanges 111 .

[0076] like Figure 6 and Figure 7 As shown, the inflow hole 140 a communicates with an inlet portion of the cooling chamber 130 where the spiral guide 133 starts, so that the inflow coolant starts to flow from the center portion of the spiral guide 133 .

[0077] Therefore, the distribution cooling pipe 140 can enable the coolant supplied to the first supply channel 142 and the second supply channel 143 respectively to contact the entire surface of the burner 113 in the process of flowing into each cooling chamber 130 through each connecting hole, so that the entire burner 113 can be continuously heat exchanged using the initially supplied coolant.

[0078] On the other hand, Figure 5 As shown, a clustering baffle 144 is provided inside each of the first supply channel 142 and the second supply channel 143 of the distribution cooling pipe 140 . The clustering baffle 144 is in a plate-shaped ring shape with an inclination ranging from 25 degrees to 35 degrees.

[0079] The outer periphery of the cluster baffle 144 is fixed to the inner circumference of the distribution cooling pipe 140, and the inner inner diameter passes through the outer circumference of the burner 113 and is separated from the outer circumference, forming a gap t between the inner diameter and the outer circumference of the burner 113 for the coolant to pass through.

[0080] The above-mentioned gap t makes the flow rate of the coolant passing through the gap t as follows Figure 5 As shown by the arrows in the enlarged view, the heat is concentrated on the edge of the end portion on both sides of the burner port 113, guiding the concentrated heat exchange on the edge that is continuously under pressure due to the reaction between the combustion gas and the crude oil, thereby fundamentally preventing the inner diameter of the edge A, which is the relatively fragile portion, from melting due to long-term exposure to a high-temperature environment.

[0081] At this time, if the inclination of the clustering baffle 144 is less than or equal to 25 degrees, the inclination is relatively gentle, and the flowing coolant hits the clustering baffle 144 and forms a vortex, resulting in stagnation, which slows down the flow through the gap t and the heat exchange of the fragile part A cannot be concentrated. On the other hand, if the inclination is greater than or equal to 35 degrees, the inclination is relatively steep, and the coolant passes through the gap t too quickly, which reduces the heat exchange efficiency of the fragile part A.

[0082] Therefore, it is most ideal to keep the inclination of the cluster baffle 144 within the range of 25 degrees to 35 degrees. Within this inclination range, the flow rate of the coolant passing through the gap t can maximize the heat exchange of the fragile part A.

[0083] The coolant supply pipe 150 is composed of a pair of Figures 4 to 7 As shown, the coolant supply pipe 150 is directly installed in the first supply flow channel 142 and the second supply flow channel 143 to supply the coolant.

[0084] The coolant discharge pipe 160 is composed of a pair of Figures 4 to 7 As shown, coolant discharge pipes 160 are respectively installed in the cooling housings 131 of the cooling chambers 130 provided in the flanges 111 to discharge the coolant flowing through the burner 113 and the cooling chamber 130 and performing heat exchange.

[0085] At this time, the coolant discharged through the coolant discharge pipe 160 flows into a cooling tower not shown, and the coolant cooled by the cooling tower is supplied to the first supply flow channel 142 and the second supply flow channel 143 again through the coolant supply pipe 150, and performs heat exchange on the reaction furnace by continuing to circulate.

[0086] On the other hand, a plurality of support members 115 may be radially disposed between the pair of flanges 111 to maintain the flanges 111 in a spaced-apart state.

[0087] That is, the radial support members 115 fundamentally prevent the separated flanges 111 from tilting to any side, thereby maintaining the connection state between the structures fixed by welding.

[0088] In the present embodiment, it is shown that the support member 115 is provided between the pair of cooling chambers 130 , but the position thereof is not limited.

[0089] Hereinafter, the heat exchange process of the carbon black reaction furnace 100 according to the present invention will be described with reference to the accompanying drawings.

[0090] When the raw oil is supplied to the carbon black reaction furnace 100 through the injection nozzle 120 , the inflowing combustion gas and the supplied raw oil react at high temperature inside the combustion port 113 to generate a mixed gas containing carbon black.

[0091] At this time, the coolant is supplied to the first supply flow channel 142 and the second supply flow channel 143 of the distribution cooling pipe 140 through the two coolant supply pipes 150 , respectively, to cool the carbon black reaction furnace 100 .

[0092] The coolant supplied to the first supply flow passage 142 and the second supply flow passage 143 exchanges heat with the burner port 113 by coming into contact with the burner port 113 while flowing inside the first supply flow passage 142 and the second supply flow passage 143 .

[0093] The coolant passing through the burner 113 is accelerated in the process of passing through the gap t of the cluster baffle 144, and Figure 5 As shown in the enlarged view of FIG, heat exchange is concentrated on the fragile portion A at the end of the burner 113.

[0094] The coolant passing through the fragile portion A flows into the spiral guide 133 of the cooling chamber 130 through the inflow hole 140 a and flows in a spiral direction along the spiral guide 133 while being spread over the entire surface of the flange 111 .

[0095] At this time, the coolant contacts the flange 111 and exchanges heat with the coolant while flowing along the spiral guide 133 , and is finally supplied to a cooling tower (not shown) through the coolant discharge pipe 160 .

[0096] The coolant supplied to the cooling tower is supplied to the first supply flow channel 142 and the second supply flow channel 143 again through the coolant supply pipe 150 in a low-temperature state, and is repeatedly circulated inside the carbon black reaction furnace 100 for heat exchange.

[0097] As described above, according to the carbon black reactor of the present invention, the burner port of the carbon black reactor is made of a heat-resistant metal material, and the cooling efficiency of the burner port heated to a high temperature is improved by supplying a coolant in both directions. The supplied coolant flows through the burner port in an air accumulation state and cools the burner port, thereby having an excellent effect of fundamentally preventing the burner port diameter from changing due to continuous exposure to high temperature as in the prior art.

[0098] In particular, the structural effect of concentrating the flowing coolant at the fragile portion around the diameter of the burner tip, thereby further enhancing the stability of the fragile portion, is also very outstanding.

[0099] Furthermore, since the shape of the burner port of the carbon black reactor is maintained, the quality of the produced carbon black can be kept stable, and most importantly, no refractory waste is generated as before.

[0100] The carbon black reactor of the present invention has been described above through preferred embodiments and drawings, but this is only to help understand the present invention and is not intended to limit the technical scope of the present invention.

[0101] That is, those skilled in the art can make various changes or improvements without departing from the technical spirit of the present invention, and such changes or improvements fall within the technical scope of the present invention in terms of the interpretation of the claims.
