Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixed gas technology, specifically to a flue gas mixing and heating device. Background Technology
[0002] In industrial production processes, flue gas mixing is a crucial step in improving energy efficiency and reducing pollutant emissions. Traditional flue gas mixing technologies suffer from problems such as uneven mixing, high energy consumption, and poor temperature control accuracy.
[0003] In the prior art, such as the furnace drying gas pipe device of a hydrogen-rich carbon circulating furnace with announcement number CN218175006U, a gas-fired medium is used. The furnace is dried by the flue gas generated by the combustion of the furnace drying device, so that the entire blast furnace masonry and furnace top equipment are gradually heated to near the production state. In order to ensure that the carbon bricks of the furnace bottom and the side wall of the hearth can be heated evenly and the moisture dried, the furnace drying device is prepared in 3 sets, one set equipped with cold air and two sets used for heating by the combustion of flue gas.
[0004] In the above, the gas can be heated and discharged through the coordinated use of multiple systems. However, after reading the technical solution, it is found that when the cold air flows inside the oven, eddies or blockages are easily generated in the middle area, resulting in greater pollution of the discharged gas. In addition, after the cold air is filled into the oven, it is easy to clump together at the bottom, which may lead to uneven density of the mixed gas and affect stable discharge. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a flue gas mixing and heating device, which can effectively solve the problem that when cold air flows inside the oven, eddies or blockages are easily generated in the middle area, resulting in greater pollution of the exhaust gas.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a flue gas mixing and heating device, including a base frame, an inclined surface on the inner side of the base frame, a flue gas pipe and a wind pipe passing through the outer side of the base frame, and an air volume compression component in the inner cavity of the base frame.
[0008] The air volume compression assembly includes a cylinder, and an mounting plate is fitted on the outer surface of the cylinder. The mounting plate is adapted to be installed on the top of the base frame, and a top plate is adapted to be installed on the output end of the cylinder. A side post is provided on the outer side of the top plate, and a spring is fitted on the outer surface of the side post. One end of the spring is fixedly connected to a lower plate, and a deflection plate is rotatably fitted on the bottom of the lower plate. The deflection plate is equipped with an eddy current removal assembly.
[0009] Furthermore, the eddy current removal assembly includes a support spring that abuts against the side of the deflection plate. The support spring is installed in the inner compartment of the base frame. The outer surface of the deflection plate is fitted with shovel teeth. The bottom of the shovel teeth is movably engaged with a translation tooth plate. An extension rod is fixedly connected to the end face of the translation tooth plate.
[0010] Furthermore, one of the extension rods is fitted with a rotating member, the rotating member including a bevel gear rotatably sleeved with the end face of the extension rod, the end face of the bevel gear being movably engaged with a separator ring, and the inner side of the separator ring being rotatably connected to a base.
[0011] Furthermore, a heating wire is provided inside the base frame, and the heating wire is kept at a certain distance from the top plate.
[0012] Furthermore, the base is fixedly connected to the inner side of the base frame, and there are several partition rings, with the same ring track fixedly connected to the upper surface of each partition ring.
[0013] Furthermore, the same ring channel is slidably fitted with a conical bucket via an adapter rod, the outer surface of the conical bucket is snapped into another extension rod, and the center of the conical bucket coincides with the center of the separating ring.
[0014] Furthermore, an inner ring is fixedly connected to the inner side of the conical bucket. The inner rings are spaced apart, and a positioning plate is fitted onto the upper surface of the inner rings.
[0015] Furthermore, an air outlet is provided on the inner side of the base frame, and the air outlet is arranged parallel to the flue pipe and the wind pipe.
[0016] Beneficial effects
[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0018] 1. An inclined surface is set on the inner side of the base frame, which allows the mixed gas to rise along the inclined surface, reducing the formation of lateral vortices. A flue gas pipe and a wind pipe are installed through the outer side of the base frame, allowing the flue gas and wind to directly enter the interior of the base frame. Then, the cylinder is connected to the top plate. After the cylinder is activated, it pushes the top plate to move linearly. After the lower plate contacts the inclined surface, it squeezes the spring inward, thus making the lower plate stably fit with the inclined surface. Then the lower plate continues to move, and the deflection plate set at the bottom contacts the inclined surface again and deflects itself. Then, it works with the vortex removal component. Through the driving action of the cylinder, the mixed gas in the base frame can be compressed to increase the density of the mixed gas, making the gas discharge more uniform. The compressed mixed gas can be affected by the vortex removal component to further reduce the mixing vortex.
[0019] Second, a support spring is then installed on the side of the deflection plate to provide support for the deflection plate. Next, the deflection plate drives the shovel teeth to engage with the translation tooth plate, which in turn pushes the extension rod. The corner teeth move closer to the separator ring, and the corner teeth push the separator ring, causing the separator ring to rotate along the outer surface of the base. When the mixed gas comes into contact with the separator ring, the gas mass is rotated and separated, which significantly solves the problem of gas accumulation. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The present invention will be further described below with reference to the embodiments.
[0029] See attached document Figure 1-5 A flue gas mixing and heating device includes a base frame 1, an inclined surface 11 is provided on the inner side of the base frame 1, a flue gas pipe 2 and a wind pipe 3 are provided through the outer side of the base frame 1, and an air volume compression component 5 is fitted in the inner cavity of the base frame 1.
[0030] The air volume compression component 5 includes a cylinder 51. A mounting plate 52 is fitted on the outer surface of the cylinder 51. The mounting plate 52 is adapted to be installed on the top of the base frame 1. A top plate 53 is adapted to be installed at the output end of the cylinder 51. A side post 54 is provided on the outer side of the top plate 53. A spring 55 is fitted on the outer surface of the side post 54. One end of the spring 55 is fixedly connected to a lower plate 56. A deflection plate 57 is rotatably fitted at the bottom of the lower plate 56. The deflection plate 57 is equipped with an anti-eddy current component 6.
[0031] An inclined surface 11 is provided on the inner side of the base frame 1, which allows the mixed gas to rise along the inclined surface 11, reducing the formation of lateral vortices. A flue gas pipe 2 and a wind pipe 3 are provided through the outer side of the base frame 1, allowing the flue gas and wind to directly enter the interior of the base frame 1. Then, the cylinder 51 is connected to the top plate 53. After the cylinder 51 is activated, it pushes the top plate 53 to move linearly. After the lower plate 56 contacts the inclined surface 11, it squeezes the spring 55 inward, thereby making the lower plate 56 stably fit against the inclined surface 11. Then, the lower plate 56 continues to move, and the deflection plate 57 set at the bottom contacts the inclined surface 11 again and deflects itself. Then, it works with the vortex removal component 6. Through the driving action of the cylinder 51, the mixed gas in the base frame 1 can be compressed, thereby increasing the density of the mixed gas, making the gas discharge more uniform, and the compressed mixed gas can be affected by the vortex removal component 6, further reducing the mixing vortex and improving the purity of the mixed gas.
[0032] The eddy current removal assembly 6 includes a support spring 61 that abuts against the side of the deflection plate 57. The support spring 61 is installed in the inner compartment of the base frame 1. The outer surface of the deflection plate 57 is fitted with a shovel tooth 62. The bottom of the shovel tooth 62 is movably engaged with a translation tooth plate 63. The end face of the translation tooth plate 63 is fixedly connected with an extension rod 64. One of the extension rods 64 is fitted with a rotating member 65. The rotating member 65 includes a bevel tooth 651 that is rotatably sleeved with the end face of the extension rod 64. The end face of the bevel tooth 651 is movably engaged with a separator ring 652. The inner side of the separator ring 652 is rotatably connected to a base 653.
[0033] Then, a support spring 61 is installed against the side of the deflection plate 57 to provide support for the deflection plate 57. Next, the deflection plate 57 drives the shovel tooth 62 to engage with the translation tooth plate 63, so that the translation tooth plate 63 pushes the extension rod 64, and the angle tooth 651 moves closer to the separator ring 652. The angle tooth 651 pushes the separator ring 652, so that the separator ring 652 rotates along the outer surface of the base 653. When the mixed gas comes into contact with the separator ring 652, the gas mass is rotated and separated, which significantly improves the problem of gas accumulation.
[0034] A heating wire 4 is installed inside the base frame 1. The heating wire 4 is kept at a certain distance from the top plate 53. The base 653 is fixedly connected to the inner side of the base frame 1. There are several partition rings 652. The upper surface of the several partition rings 652 is fixedly connected to the same ring channel 654.
[0035] The heating wire 4 allows for direct heating of the mixed gas, facilitating temperature rise.
[0036] A conical bucket 655 is slidably fitted to the same ring channel 654 via an adapter rod. The outer surface of the conical bucket 655 is snapped onto another extension rod 64. The center of the conical bucket 655 coincides with the center of the dividing ring 652. An inner lining ring 656 is fixedly connected to the inner side of the conical bucket 655. The inner lining rings 656 are spaced apart. A standing plate 657 is fitted onto the upper surface of the inner lining rings 656.
[0037] Following the above, another extension rod 64 drives the conical bucket 655 to slide along the inner side of the same ring channel 654, so that the gas separated by the dividing ring 652 re-enters the inner side of the conical bucket 655, and is blocked and divided by the inner ring 656, which helps to prevent the further formation of gas clusters. At the same time, a positioning plate 657 is adapted and installed on the upper surface of the inner ring 656 to guide the direction of the gas that is about to be discharged.
[0038] An air outlet 7 is provided on the inner side of the base frame 1. The air outlet 7 is set parallel to the flue pipe 2 and the wind pipe 3.
[0039] Parallel arrangement helps reduce gas accumulation during inlet and outlet, making gas mixing easier.
[0040] Working principle: An inclined surface is set on the inner side of the base frame, which allows the mixed gas to rise along the inclined surface, reducing the formation of lateral vortices. A flue gas pipe and a wind pipe are installed through the outer side of the base frame, allowing the flue gas and wind to directly enter the interior of the base frame. Then, the cylinder is connected to the top plate. After the cylinder is activated, it pushes the top plate to move linearly. After the lower plate contacts the inclined surface, it squeezes the spring inward, thus making the lower plate stably fit with the inclined surface. Then the lower plate continues to move, and the deflection plate set at the bottom contacts the inclined surface again, deflecting itself. This works in conjunction with the vortex removal component. Through the driving action of the cylinder, the mixed gas in the base frame can be compressed, thereby increasing the density of the mixed gas, making the gas discharge more uniform, and the compressed mixed gas can be further reduced by the vortex removal component, improving the purity of the mixed gas.
[0041] Then, a support spring is installed on the side of the deflection plate to provide support for the deflection plate. Next, the deflection plate drives the shovel teeth to engage with the translation tooth plate, so that the translation tooth plate pushes the extension rod and the corner teeth move closer to the separator ring. The corner teeth push the separator ring, so that the separator ring rotates along the outer surface of the base. When the mixed gas comes into contact with the separator ring, the gas mass is rotated and separated, which significantly improves the problem of gas accumulation.
[0042] Following the above, another extension rod drives the conical bucket to slide along the inner side of the same ring channel, allowing the gas separated by the dividing ring to re-enter the inner side of the conical bucket, where it is blocked and separated by the inner ring, which helps to prevent the further formation of gas clusters. At the same time, a positioning plate is fitted and installed on the upper surface of the inner ring to guide the direction of the gas that is about to be discharged.
[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
