Description

Technical Field

[0001] The invention belongs to the technical field of carbon black reactors, and in particular relates to a carbon black reactor capable of improving quality and efficiency. Background Art

[0002] Carbon black is a pure carbon produced by incomplete combustion. It is an amorphous carbon. In its normal state, it is a light, loose and extremely fine black powder with a very large specific surface area. Carbon black is an indispensable chemical raw material in industry and a modified additive for most plastic and rubber products. The carbon black currently produced is mainly prepared by the oil furnace method. Additives, fuel gas and preheated air are introduced into the reactor, and the mixture is burned in the combustion chamber. Then, the preheated crude oil is sprayed into the reactor, and incomplete combustion is carried out in a relatively closed space and a limited oxygen environment. Carbon black is produced in a high temperature environment of about 800°C. In the prior art, the crude oil entering the reactor is generally injected into the reactor through an oil nozzle perpendicular to the axis of the reactor. The atomized oil is sprayed out, and the flame produced by the combustion will move to the right. At this time, the direction of the flame will be perpendicular to the nozzle, so that the crude oil may flash back when it is sprayed out and burned: in order to make the crude oil generate as much carbon black as possible during incomplete combustion, in the prior art, the speed of the crude oil sprayed through the nozzle is generally controlled within a smaller range per unit time, so that the crude oil can be completely converted into carbon black during incomplete combustion. However, the lower flow rate of the crude oil may sometimes be lower than the flame combustion speed in the combustion chamber, and there is a certain probability of causing flashback. The oil pipeline connected to the nozzle is also connected, which may cause combustion or even explosion and other dangerous phenomena, so it is urgent to solve the problem. Summary of the invention

[0005] As a preferred solution of the present invention, the throat pipe sections are arranged in four groups, and the transfer bin is installed on the top of the leftmost throat pipe section.

[0006] As a preferred solution of the present invention, the axis of the guide column is parallel to the axis of the reactor body, the two groups of guide columns are distributed in parallel front and back, the top cross-sectional shape of the sealing plate is "U"-shaped, the left side of the shift block 1 abuts against the inner wall of the transfer bin, and an oil gap is left between the side of the shift block 1 facing the oil inlet pipe and the inner wall of the transfer bin.

[0007] As a preferred solution of the present invention, the cross-sectional shape of the shift block 1 is a right triangle, the cross-sectional shape of the shift block 2 is a right trapezoid, and the inclined surfaces of the shift block 1 and the shift block 2 are parallel to each other.

[0008] As a preferred solution of the present invention, the through grooves are arranged in two groups and are symmetrically distributed on the left and right sides of the bottom of the outer surface of the through pipe. The through grooves are in the shape of long strips, and the sealing sleeves cover parts of the through grooves.

[0009] As a preferred solution of the present invention, the horizontal right-angle length of the shift block one is greater than the distance between the right side of the sealing plate and the right side of the inner wall of the transfer bin, and the number of the shift block two is one, and it is fixedly installed on the top of the connecting block on the right side.

[0010] As a preferred solution of the present invention, the thermal expansion liquid is made of kerosene or diesel and is located between the placement groove and the bottom of the inner wall of the sealing cylinder, and the other end of the heat conducting rod is adapted to be engaged in the placement groove.

[0011] As a preferred solution of the present invention, the bottom end of the fuel injection pipe is inclined to the right and faces away from the combustion chamber, and the shape of the atomizing block is a cross.

[0012] The beneficial effects of the present invention are as follows:

[0013] The device is designed with a set of brand-new transfer chambers, which cooperate with the oil inlet pipe and the oil injection pipe to realize the automatic adjustment function of the crude oil injection speed. The transfer chamber is provided to connect the oil inlet pipe and the oil injection pipe, which is responsible for the transfer of crude oil output. A through pipe located in the middle of the transfer chamber is provided, and two sets of through grooves are opened on the surface of the through pipe to provide a channel for the crude oil to pass through. The effective passing area of ​​the through groove is adjusted with the up and down movement of the sealing sleeve. The temperature of the flame of the combustion reaction in the inner cavity of the throat section is felt by the bottom of the heat conducting rod. When the temperature of the heat conducting rod is normal, it means that the injection amount is normal, and the speed of incomplete combustion of crude oil is equal to the speed of injection. When the combustion speed is greater than the injection speed, the burning flame begins to move upward and approaches the oil injection pipe and the heat conducting rod. At this time, the temperature of the heat conducting rod rises abnormally, and heats the thermal expansion liquid in the placement groove to expand its volume, and pushes the piston, the connecting block and the sealing sleeve upward, thereby reducing the area of ​​the sealing sleeve covering the through groove, increasing the effective oil passing area of ​​the through groove, and improving the injection speed of the device, thereby avoiding the occurrence of backfire.

[0014] The device is also designed with a "U"-shaped sealing plate, which is used to directly and automatically cut off the crude oil supply to the transfer bin. When the tempering phenomenon occurs inside the injection pipe, the heat-expanding liquid in the placement tank is heated by the heat-conducting rod at its highest temperature to reach the maximum expansion volume, and the piston, the connecting block and the second shift block are pushed upward to the highest position. The second shift block abuts against the first shift block, so that the first shift block is pushed to the right, driving the sealing plate to move to the right and abut against the right side of the inner wall of the transfer bin, so that the oil gap connecting the inner cavity of the transfer bin and the oil inlet pipe is squeezed to disappear, and the crude oil supply to the transfer bin is directly cut off, ensuring the safe operation of the device.

[0015] The device also redesigned the fuel injection pipe, tilting the fuel injection end of the fuel injection pipe to the right at a certain angle, so that the crude oil sprayed from the fuel injection pipe can produce a certain displacement in the horizontal direction, extending the burning time of the crude oil after being sprayed into a mist, and giving the finished carbon black a horizontal driving force to assist in the discharge of carbon black. The tilted right design can also prevent the flame from approaching the inside of the fuel injection pipe, effectively ensuring the safe operation of the device and improving reliability.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The device is designed with a set of brand-new transfer chambers 8, and cooperates with the oil inlet pipe 9 and the oil injection pipe 10 to realize the automatic adjustment function of the crude oil injection speed. The transfer chamber 8 is connected with the oil inlet pipe 9 and the oil injection pipe 10 to be responsible for the transfer of crude oil output. A through pipe 84 is provided in the middle of the transfer chamber 8, and two sets of through grooves 85 are opened on the surface of the through pipe 84 to provide a passage for the crude oil to pass through. The effective passing area of ​​the through groove 85 is adjusted with the up and down movement of the sealing sleeve 86, and the condition for triggering the adjustment depends on the heat-conducting rod 89. A set of heat-conducting rods 89 are installed inside the sealing tube 88, and the bottom of the heat-conducting rod 89 senses the combustion in the inner cavity of the throat section 21. The temperature of the reaction flame, when the temperature of the heat conducting rod 89 is normal, it means that the fuel injection amount is normal, and the speed of incomplete combustion of crude oil is equal to the speed of fuel injection. When the combustion speed is greater than the fuel injection speed, the burning flame begins to move upward and approaches the fuel injection pipe 10 and the heat conducting rod 89. At this time, the temperature of the heat conducting rod 89 rises abnormally, and heats the thermal expansion liquid in the placement groove 813, causing its volume to expand and push the piston 810, the connecting block 811 and the sealing sleeve 86 upward, thereby reducing the area of ​​the sealing sleeve 86 covering the through groove 85, increasing the effective oil passing area of ​​the through groove 85, and improving the fuel injection speed of the device, thereby avoiding the occurrence of backfire.

[0028] The throat sections 21 are arranged in four groups, and the transfer bin 8 is installed on the top of the leftmost throat section 21;

[0029] The reactor body 2 is composed of multiple groups of throat sections 21 and combustion chambers 22 which are connected and fixed to each other through flanges and bolts. The transfer chamber 8 is located close to the combustion chamber 22, which is conducive to the immediate combustion of crude oil after being injected into the inner cavity of the throat section 21.

[0030] The axis of the guide column 81 is parallel to the axis of the reactor body 2, and the two groups of guide columns 81 are parallelly distributed front and back. The top view cross-section of the sealing plate 82 is "U" shaped. The left side of the shift block 83 abuts against the inner wall of the transfer bin 8, and an oil gap is left between the side of the shift block 83 facing the oil inlet pipe 9 and the inner wall of the transfer bin 8.

[0031] The device is also designed with a "U"-shaped sealing plate 82, which is used to directly and automatically cut off the crude oil supply to the transfer bin 8. When the tempering phenomenon occurs inside the injection pipe 10, the heat-conducting rod 89 heats the heat-expanding liquid in the placement groove 813 at its highest temperature to make it reach the maximum expansion volume, and pushes the piston 810, the connecting block 811 and the second shift block 812 to the highest position. The second shift block 812 abuts against the first shift block 83, so that the first shift block 83 is pushed to the right, driving the sealing plate 82 to move to the right and abut against the right side of the inner wall of the transfer bin 8, so that the oil gap connecting the inner cavity of the transfer bin 8 and the oil inlet pipe 9 is squeezed to disappear, and the crude oil supply to the transfer bin 8 is directly cut off, thereby ensuring the safe operation of the device.

[0032] The cross-sectional shape of the first shift block 83 is a right triangle, the cross-sectional shape of the second shift block 812 is a right trapezoid, and the inclined surfaces of the first shift block 83 and the second shift block 812 are parallel to each other;

[0033] When the inclined surfaces of the shift block 1 83 and the shift block 2 812 are in contact, relative sliding can occur, and the shift block 1 83 will be pushed to the right by the shift block 2 812, thereby realizing the function of cutting off the crude oil supply in the inner cavity of the transfer bin 8.

[0034] The through grooves 85 are arranged in two groups and are symmetrically distributed on the left and right sides of the bottom of the outer surface of the through pipe 84. The through grooves 85 are in the shape of long strips, and the sealing sleeves 86 cover part of the through grooves 85.

[0035] The through grooves 85 are arranged in two groups to ensure the minimum oil injection amount during the operation of the device. The long strip design of the through grooves 85 enables the sealing sleeve 86 to dynamically adjust the effective passage area of ​​the through grooves 85 that can actually pass the crude oil by changing the area covered by the sealing sleeve 86 when the sealing sleeve 86 moves up and down.

[0036] The horizontal right-angle length of the shift block 1 83 is greater than the distance between the right side of the sealing plate 82 and the right side of the inner wall of the transfer bin 8. The number of the shift block 2 812 is one, and it is fixedly installed on the top of the right connecting block 811.

[0037] The horizontal right-angle length of the shift block 1 83 is the maximum distance it can move to the right. This design ensures that even if the sealing plate 82 is tightly against the inner wall of the transfer bin 8, the shift block 2 812 and the inclined surface of the shift block 1 83 can still maintain contact.

[0038] The thermal expansion liquid is made of kerosene or diesel and is located between the placement groove 813 and the bottom of the inner wall of the sealing cylinder 88. The other end of the heat conducting rod 89 is adapted to fit in the placement groove 813.

[0039] The volume of the thermal expansion liquid expands when heated, and the piston 810 can automatically move upward. In this device, the maintenance personnel can freely select the raw materials according to the actual situation.

[0040] The bottom end of the fuel injection pipe 10 is tilted to the right and faces away from the combustion chamber 22, and the atomizing block 11 is in the shape of a cross;

[0041] The device also redesigns the fuel injection pipe 10, and tilts the fuel injection end of the fuel injection pipe 10 to the right at a certain angle, so that the crude oil sprayed from the fuel injection pipe 10 can produce a certain displacement in the horizontal direction, extending the burning time of the crude oil after being sprayed into a mist, and giving the finished carbon black a horizontal driving force to assist in the discharge of the carbon black. The design of tilting to the right can also prevent the flame from approaching the interior of the fuel injection pipe 10, effectively ensuring the safe operation of the device and improving reliability.

[0042] Working principle:

[0043] First, the air supply pipe 3, the additive supply pipe 4, and the gas supply pipe 5 are connected to the preheated air, additive, and natural gas, respectively, and enter the combustion chamber 22, and are ignited and burned by the igniter located at the top of the combustion chamber 22. The flame begins to move to the right and gradually approaches the fuel injection pipe 10;

[0044] Then, the crude oil enters the inner cavity of the transfer bin 8 through the oil inlet pipe 9. Figure 4 As shown, the sealing plate 82 is pushed to the left by the crude oil, so that an oil gap is formed between the right side of the sealing plate 8 and the right side of the inner wall of the transfer bin 8. The crude oil quickly fills the entire inner cavity of the transfer bin 8 through the oil gap, and then enters the through pipe 84 and the oil injection pipe 10 through the through groove 85, and finally is sprayed and atomized into the inner cavity of the throat section 21 through the atomizing block 11, and is incompletely burned with the flame and the air entering the inner cavity of the throat section 21 and the combustion chamber 22 to form carbon black. When it moves to the right along the inner cavity of the throat section 21, the cooling water pipe 6 sprays cooling water and terminates the reaction, so that the carbon black is discharged through the discharge pipe 7;

[0045] Finally, when the injection speed through the injection pipe 10 is too slow, the crude oil entering the inner cavity of the throat section 21 is quickly consumed. At this time, the flame generated by the combustion will move upwards towards the injection pipe 10 and the heat conducting rod 89. After sensing the abnormally high temperature, the heat conducting rod 89 will transfer the heat to the heat expansion liquid in the placement groove 813, causing the liquid to expand in volume, pushing the piston 810, the connecting block 811 and the sealing sleeve 86 upwards, and compressing the spring 87 to generate a downward rebound force. At this time, the sealing sleeve 86 moves upwards, causing the sealing sleeve 86 to The area covered by the through groove 85 is reduced, thereby increasing the passing area of ​​the crude oil in the through groove 85 and increasing the crude oil passing speed per unit time, thereby realizing the automatic adjustment function of the crude oil injection speed. When the flame is too close to the fuel injection pipe 10, the temperature of the heat conducting rod 89 reaches the highest state. At this time, the shift block 812 is driven upward by the piston 810 and the connecting block 811, and abuts against the shift block 83, so that the shift block 83 and the guide column 81 are pushed to the right, the oil gap is blocked, and the crude oil input is directly cut off.
