Description

TECHNICAL FIELD

[0001] The utility model relates to the field of roasting equipment, and specifically relates to a burner for anode carbon block roasting. BACKGROUND

[0002] For anode carbon block, after calcined petroleum coke and pitch are mixed, the mixture is conveyed to a forming device for forming, and then the anode carbon block is roasted, so that the finished product of the anode carbon block can be prepared. For the roasting environment of the anode carbon block, the anode carbon block needs to be subjected to high-temperature roasting operation in an oxygen-free environment, so that the inner and outer layers of the anode carbon block can meet the use requirements of the anode end of the electrolytic cell. Therefore, the anode carbon block roasting operation is very important. The existing roasting method needs to convey natural gas to the anode carbon block roasting furnace, so that a high temperature is generated in the roasting furnace, thereby reaching the roasting temperature of the anode carbon block. However, when roasting in this way, the natural gas combustion flame directly roasts the anode carbon block, so that the roasting temperature of the surface of the anode carbon block cannot be controlled. Moreover, because the natural gas is conveyed and contacts less oxygen, the conveyed natural gas cannot be completely burned when the natural gas is conveyed to the roasting furnace for roasting, thereby causing waste of fuel and failing to better act on the anode carbon block roasting link.

[0003] Based on the above problems, a burner for anode carbon block roasting is needed, which can ensure that the roasted anode carbon block meets the production requirements, does not cause roasting failure of the anode carbon block, and ensures that the natural gas input into the roasting furnace can be completely burned to provide heat, thereby ensuring that the anode carbon block is roasted to the maximum extent. SUMMARY

[0004] The utility model aims at providing a burner for anode carbon block roasting, which can ensure that the roasted anode carbon block meets the production requirements, does not cause roasting failure of the anode carbon block, and ensures that the natural gas input into the roasting furnace can be completely burned to provide heat, thereby ensuring that the anode carbon block is roasted to the maximum extent.

[0005] The utility model discloses a technical scheme to realize the above-mentioned purpose:

[0006] A burner for anode carbon block roasting, comprising an input part and a combustion part, the input part is connected to the combustion part; the combustion part comprises a combustion pipe and an outer sleeve, the outer sleeve is sleeved outside the combustion pipe, and an air inlet hole is formed in the outer sleeve; a spiral flow dividing member is arranged at the outlet end position inside the combustion pipe, and the spiral flow dividing member divides the natural gas sprayed into the combustion pipe.

[0007] The spiral diverter is a spiral guide column, and spiral guide grooves are arranged in a circumferential array on the side of the spiral guide column. When natural gas passes through the spiral guide column, it flows into multiple spiral guide grooves.

[0008] The multiple air inlets are arranged in a circumferential array on the outer tube, and each air inlet is located at a different height on the outer tube.

[0009] The outlet end of the combustion tube is positioned beyond the positions of the multiple air inlets, and the lower end of the outer sleeve is much longer than the outlet end of the combustion tube.

[0010] The input section includes an input pipe and a docking chuck. The input pipe is connected to the combustion pipe of the combustion section. The docking chuck is located on the outside of the input pipe and is used to limit the length of the input pipe inserted into the roasting furnace.

[0011] A docking cap is provided at the input end of the input pipe, and the docking cap is adapted to the natural gas hose.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This device, when configured, utilizes an input section and a combustion section to deliver and burn natural gas. The combustion section incorporates a spiral diverter within the combustion tube. This diverter distributes the natural gas entering the combustion tube, directing it outwards in various directions. Simultaneously, the high-velocity gas exiting the combustion tube creates an inlet port that allows oxygen to enter the outer casing and oxidize at the end of the combustion tube. This maximizes the combustion of the dispersed natural gas, ensuring complete combustion and heat release. This, in turn, maximizes the heating of the anode carbon blocks in the roasting furnace, ensuring optimal roasting performance. Attached Figure Description

[0021] The utility model will be further explained in combination with specific embodiments. It should be understood that these embodiments are only used for illustrating the utility model and are not used for limiting the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the present application.

[0022] For the traditional combustor, there are some drawbacks when baking anode carbon blocks. First, because in the process of conveying natural gas to the baking furnace for baking anode carbon blocks, the natural gas input into the combustion furnace is wasted due to insufficient combustion at the combustor position; second, because the natural gas is not fully combusted, it is easy for the natural gas to carry the flame directly to the surface of the anode carbon blocks, causing the anode carbon blocks to crack due to the direct action of the flame, which is not conducive to the baking operation of the anode carbon blocks.

[0023] Therefore, through the above problems, the need for a kind of anode carbon block roasting burner, including input 1, combustion part 2, the input 1 is connected with the combustion part 2 docking connection;The input part 1 is used for the docking of natural gas pipeline and the input task of natural gas, and the combustion part 2 is mainly used in the internal space of the roasting furnace to realize the heating of the roasting furnace space. The combustion part 2 includes combustion pipe 3, sleeve pipe 4, the sleeve pipe 4 is arranged outside the combustion pipe 3, and the air inlet hole 5 is formed on the sleeve pipe 4;Spiral flow dividing piece 6 is arranged at the outlet end position in the combustion pipe 3, and the natural gas sprayed in the combustion pipe 3 is divided by the spiral flow dividing piece 6. For the sleeve pipe 4, it is used for the entering operation of oxygen, and the combustion pipe 3 in the inside is used for the output task of natural gas. In the initial stage, natural gas flows out from the port position of the combustion pipe 3, at this time, the outflow of natural gas will produce a fast flow rate, so that the pressure of the port position of the combustion pipe 3 becomes smaller, so that the air in the external environment enters the inside of the sleeve pipe 4 under the action of air pressure and burns with the natural gas at the end position of the combustion pipe 3;After the combustion of natural gas and oxygen in the air, the heat generated causes the pressure to further decrease, so that in the continuous combustion state, the flame only appears at the end position of the combustion pipe 3, so as to ensure that the preparation material of the combustion pipe 3 meets the long-time combustion demand of natural gas. Most importantly, when the combustion pipe 3 is arranged, the spiral flow dividing piece 6 is arranged at the position close to the outlet end in the combustion pipe 3. The spiral flow dividing piece 6 can divide the natural gas sprayed in the combustion pipe 3, so that the natural gas can flow out at the port position of the combustion pipe 3, and the conveying rate of the natural gas can be slowed down, so that the natural gas can better contact with oxygen to burn, so as to achieve the purpose of burning as much natural gas as possible.

[0024] The above structure is further provided and optimized as follows:

[0025] The spiral flow dividing piece 6 is a spiral flow guide column 7, and a spiral flow guide groove 8 is arranged in a circumferential array on the side surface of the spiral flow guide column 7. When the natural gas flows into the plurality of spiral flow guide grooves 8 through the spiral flow guide column 7, the high-flow-rate natural gas is buffered through the spiral flow guide groove 8, so as to reduce the flow speed of the natural gas;At the same time, the natural gas is dispersed at the port position of the combustion pipe 3, so that the natural gas can diffuse in multiple directions outward at the port position of the combustion pipe 3, so as to achieve the purpose of fully contacting the oxygen.

[0026] The plurality of air inlet holes 5 are arranged in a circular array on the outer sleeve 4, and each air inlet hole 5 is located at a different height position of the outer sleeve 4; so that air can enter the combustion tube 3 from different directions at different size positions of the outer sleeve 4, so that the natural gas divided by the spiral flow divider 6 can be in contact with oxygen in the air at each position to maximize combustion, avoiding incomplete combustion of natural gas so that the flame directly acts on the anode carbon block without the burner. The outlet end position of the combustion tube 3 is arranged beyond the position of the plurality of air inlet holes 5, and the lower end position of the outer sleeve 4 is longer than the outlet end position of the combustion tube 3, so as to ensure that even if the natural gas cannot be completely burned at the port position of the combustion tube 3, because of the lengthened arrangement of the outer sleeve 4, it can also ensure that the natural gas will not escape from the outer sleeve 4 and directly act on the internal space of the roasting furnace.

[0027] The input part 1 includes an input pipe 9 connected to the combustion tube 3 of the combustion part 2, and a docking chuck 10 arranged outside the input pipe 9 to limit the length of the input pipe 9 inserted into the roasting furnace, facilitating the installation and arrangement of the device. A docking end cap 11 is arranged at the input end position of the input pipe 9, which is adapted to the natural gas hose to facilitate the connection operation of the natural gas pipe and the device.

[0028] Therefore, the burner for roasting anode carbon blocks can ensure that the roasted anode carbon blocks meet the production requirements and do not have roasting failure problems, and can ensure that the natural gas input into the roasting furnace can be completely burned to provide heat, so as to ensure the maximum roasting operation of the anode carbon blocks.
