There is an air inlet box at the front end of the combustion-supporting air inlet. The air inlet box is provided with a combustion-supporting air inlet and a recycled flue gas inlet. Both the combustion-supporting air inlet and the recycled flue gas inlet are divided into two channels, and each channel is designed with an electric air regulating device, which are respectively connected to the swirl air, direct current air, and diffusion air of the ventilation channel, providing an ultra-low nitrogen hydrogen burner with high efficiency, energy saving, safety, and environmental protection.

However, before combustion operation, the gas may be unevenly mixed between the gases, which may affect the combustion efficiency and fuel utilization rate of the equipment. Therefore, a hydrogen burner with sufficient hydrogen-oxygen mixing and isolation of hydrogen leakage is designed. Summary of the Invention

[0005] To overcome the above defects, embodiments of the present invention provide a hydrogen burner, which solves the technical problem that in the prior art, the gas may be unevenly mixed before combustion, thereby affecting the combustion efficiency and fuel utilization rate of the equipment.

An ignition tube is fixedly penetrated through the surface of the burner body. A mixing cylinder is fixedly installed inside the burner body. A motor is fixedly installed at the bottom of the inner wall of the burner body. A mixing device for mixing hydrogen and oxygen is arranged on the surface of the burner body. The mixing device includes a hydrogen gas pipe, which is fixedly penetrated through the surface of the burner body. An air supply pipe is fixedly penetrated through the surface of the burner body. A gas stirring ring is fixedly installed at the output end of the motor. A drying cylinder is fixedly installed on the inner wall of the mixing cylinder. A blower is fixedly installed inside the burner body. A gas transmission pipe is fixedly penetrated through the top of the mixing cylinder.

The end of the gas transmission pipe away from the mixing cylinder is fixedly installed with a flame stabilizing disc. An electric rotating rod is fixedly installed on the surface of the burner body. A partition board is fixedly installed at the output end of the electric rotating rod. The mixing uniformity of hydrogen and combustion-supporting gas is improved, enabling the two gases to fully contact, providing more sufficient conditions for subsequent combustion, ensuring more complete and stable combustion, and enhancing the combustion efficiency.

[0007] For example, in a hydrogen burner provided by at least one embodiment of the present invention, it further includes: the hydrogen gas pipe is fixedly penetrated through the surface of the mixing cylinder, the air supply pipe is fixedly penetrated through the surface of the mixing cylinder. A desiccant for drying the mixed gas is arranged inside the drying cylinder, achieving isolation of the equipment in case of hydrogen leakage, effectively avoiding serious safety accidents such as fires and explosions caused by hydrogen leakage, and ensuring the safety of the equipment, the surrounding environment and personnel; the gas stirring ring is shaped like a semi-circle, the blower is fixedly penetrated through the top of the mixing cylinder. A hydrogen concentration sensor is arranged inside the burner body. The hydrogen concentration sensor includes a sensing module and a transmission module. The transmission module is electrically connected to the electric rotating rod, reducing the phenomenon of incomplete combustion caused by insufficient mixing, reducing energy waste and pollutant emissions.

[0008] According to another aspect, at least one embodiment of the present invention further provides a hydrogen burner, comprising: a drying device for drying the mixed gas inside the mixing barrel is provided on the inner wall of the mixing barrel, the drying device comprises a filter plate, the filter plate is slidably mounted on the inner wall of the mixing barrel, a fixing ring is fixedly mounted on the output end of the motor, a stirring rod is rotatably penetrated on the surface of the fixing ring, a turntable is fixedly mounted on the circumferential surface of the stirring rod, a fixing disk is fixedly mounted on the output end of the motor, a chamfered block is fixedly mounted on the bottom of the fixing disk, a telescopic elastic rod is fixedly mounted on the circumferential surface of the motor, a sleeve plate is sleeved on the circumferential surface of the motor, a limiting plate 1 is fixedly mounted on the surface of the sleeve plate, a closing plate 1 is fixedly mounted inside the hydrogen pipe, the contact area between the desiccant and the mixed gas is increased, thereby increasing the drying rate, so that the mixed gas can reach the required degree of dryness faster, ensuring that the gas entering the combustion link is dry and pure, avoiding the influence of gas moisture on the combustion effect, and also preventing the humid gas from corroding the internal components of the equipment, thereby extending the service life of the equipment.

[0009] The circumferential surface of the stirring rod is provided with a stirring plate, the turntable is in contact with the circumferential surface of the fixed ring, the surface of the limiting plate one is provided with an air outlet one, the surface of the closing plate one is provided with an air outlet two, and the air outlet one and the air outlet two are overlapped, thereby further improving the stirring and mixing effect of the desiccant. At this time, the fixed ring is realized to revolve while driving the stirring rod to rotate, thereby ensuring that the desiccant is in full contact with the mixed gas, maximizing the drying performance of the desiccant, and improving the drying efficiency and quality.

[0010] For example, in at least one embodiment of the present invention, a hydrogen burner is provided, which further includes: the free end of the telescopic elastic rod is fixedly connected to the sleeve plate, the surface of the bevel block is provided with an arc surface one for contacting and squeezing the cooling ring to move downward, the limit plate one is slidably connected to the inner wall of the hydrogen pipe, the number of the limit plates one is set to two, and the two limit plates one are slidably connected to the inner walls of the hydrogen pipe and the combustion-supporting gas pipe respectively, to avoid continuous supply of hydrogen when the system is abnormal or non-working, and reduce the risk of safety accidents such as explosion and fire caused by accumulation of hydrogen leakage. At the same time, discontinuous delivery of hydrogen can more flexibly adjust the hydrogen supply, so that the burner can quickly adapt to load changes and maintain good working performance.

[0011] A limiting device for restricting the gas outlet of the hydrogen gas pipe is arranged on the surface of the flame stabilizing disc. The limiting device includes a connecting rod fixedly installed on the surface of the flame stabilizing disc. A second closing plate is fixedly installed on the inner wall of the hydrogen gas pipe. A second limiting plate is slidably installed at one end of the hydrogen gas pipe close to the mixing cylinder. A linkage rod is fixedly installed at the bottom of the sleeve plate. A cleaning ring is fixedly installed on the circumferential surface of the motor. A cleaning cylinder is rotatably installed on the surface of the cleaning ring. A roller is fixedly installed on the circumferential surface of the cleaning cylinder. It is realized that hydrogen can only pass through when the combustion-supporting gas channel is opened, avoiding the separate transportation of hydrogen caused by misoperation or equipment failure, thus triggering potential safety hazards, further ensuring the safety and stability of equipment operation, and ensuring that hydrogen and combustion-supporting gas enter the combustion link in the correct sequence and conditions.

[0012] The roller contacts the drying cylinder. Brush hairs are arranged on the circumferential surface of the cleaning cylinder. The linkage rod is fixedly connected to the filter plate, avoiding being blocked by a large amount of dust or impurities, thereby affecting the drying efficiency of the drying cylinder, ensuring the normal functioning of the drying function of the drying device drying cylinder, maintaining the overall stable operation of the equipment, improving the combustion quality and equipment reliability, and at the same time reducing equipment failures and performance degradation caused by impurities and blockages.

[0013] The beneficial effects of the embodiments of the present invention are as follows: In the present invention, the output end of the motor rotates to drive the gas stirring ring to rotate. The rotation of the gas stirring ring mixes and stirs the hydrogen gas and the combustion-supporting gas inside the mixing cylinder, improving the mixing uniformity of the hydrogen gas and the combustion-supporting gas, enabling the two gases to fully contact, providing more sufficient conditions for subsequent combustion, ensuring more complete and stable combustion, enhancing the combustion efficiency, reducing the phenomenon of incomplete combustion caused by insufficient mixing, and reducing energy waste and pollutant emissions.

[0014] In the present invention, the output end of the electric rotating rod rotates to drive the partition plate to rotate. The rotation of the electric rotating rod physically isolates the flame spraying port of the burner body, realizing the isolation of the equipment when hydrogen leaks from the equipment, effectively avoiding serious safety accidents such as fires and explosions caused by hydrogen leakage, ensuring the safety of the equipment, the surrounding environment and personnel, and when the mixed gas passes through the gas transmission pipe, the cooling ring will cool the mixed gas, improving the gas utilization rate of subsequent combustion, and thus enhancing the combustion efficiency.

[0015] In the present invention, the rotation of the fixed ring stirs the desiccant inside the drying cylinder, increasing the contact area between the desiccant and the mixed gas, thereby improving the drying rate, enabling the mixed gas to reach the required drying degree faster, ensuring that the gas entering the combustion link is dry and pure, avoiding affecting the combustion effect due to humid gas, and at the same time preventing the humid gas from corroding the internal components of the equipment and extending the service life of the equipment.

[0016] In the present invention, the rotation of the turntable drives the rotation of the stirring rod. At this time, the rotation of the stirring rod drives the rotation of the stirring plate, further improving the stirring and mixing effect of the desiccant. At this time, while the fixed ring rotates around the sun, it drives the stirring rod to rotate around its own axis, ensuring full contact between the desiccant and the mixed gas, maximizing the drying performance of the desiccant, and improving the drying efficiency and quality. The first limiting plate releases the restriction on the hydrogen pipe and the combustion-supporting gas pipe. At this time, hydrogen and combustion-supporting gas enter the interior of the mixing cylinder, realizing the discontinuous transportation of hydrogen and combustion-supporting gas, avoiding continuous supply of hydrogen under abnormal or non-operating conditions of the system, reducing the risk of safety accidents such as explosion and fire caused by hydrogen leakage and accumulation. At the same time, the discontinuous supply of hydrogen can more flexibly adjust the hydrogen supply, enabling the burner to quickly adapt to load changes and maintain good working performance.

[0017] In the present invention, the second limiting plate moves downward under the action of the connecting rod until it coincides with the opening on the surface of the second closing plate. At this time, the hydrogen inside the hydrogen pipe can be transported, realizing that hydrogen can only be transported when the combustion-supporting gas channel is opened, avoiding the separate transportation of hydrogen caused by misoperation or equipment failure, thereby causing potential safety hazards, further ensuring the safety and stability of equipment operation, ensuring that hydrogen and combustion-supporting gas enter the combustion link in the correct order and conditions. The cleaning cylinder rotates to drive the brush to rotate, and the rotation of the brush scrapes off the dust or impurities blocked or attached to the surface of the drying cylinder, avoiding the reduction of the drying efficiency of the drying cylinder due to blockage by a large amount of dust or impurities, ensuring the normal functioning of the drying function of the drying cylinder of the drying device, maintaining the stable operation of the overall equipment, improving the combustion quality and equipment reliability, and at the same time reducing equipment failures and performance degradation caused by impurities and blockages.

[0026] As Figures 1 to 7 shown, it shows a hydrogen burner in an embodiment of the present invention, including a burner body 1. An ignition tube 2 is fixedly penetrated through the surface of the burner body 1. A mixing cylinder 3 is fixedly installed inside the burner body 1. A motor 4 is fixedly installed at the bottom of the inner wall of the burner body 1. A mixing device for mixing hydrogen and oxygen is arranged on the surface of the burner body 1. The mixing device includes a hydrogen gas pipe 51, and the hydrogen gas pipe 51 is fixedly penetrated through the surface of the burner body 1. An air pipe 52 for assisting combustion is fixedly penetrated through the surface of the burner body 1. A gas stirring ring 53 is fixedly installed at the output end of the motor 4. A drying cylinder 54 is fixedly installed on the inner wall of the mixing cylinder 3. A blower 55 is fixedly installed inside the burner body 1. An air delivery pipe 56 is fixedly penetrated through the top of the mixing cylinder 3. A detector 57 is fixedly installed on the inner wall of the burner body 1. A cooling ring 58 is fixedly installed on the inner wall of the burner body 1. A flame stabilizing plate 59 is fixedly installed at one end of the air delivery pipe 56 away from the mixing cylinder 3. An electric rotating rod 510 is fixedly installed on the surface of the burner body 1. A partition plate 511 is fixedly installed at the output end of the electric rotating rod 510. The electric rotating rod 510 is started under the signal action of the transmission module, and the output end of the electric rotating rod 510 rotates to drive the partition plate 511 to rotate.

[0027] In some examples, the hydrogen gas pipe 51 is fixedly penetrated through the surface of the mixing cylinder 3, the combustion-supporting gas pipe 52 is fixedly penetrated through the surface of the mixing cylinder 3, a desiccant for drying the mixed gas is arranged inside the drying cylinder 54, the mixed gas moves upward through the drying cylinder 54, and then is dried under the action of the desiccant inside the drying cylinder 54, and then the mixed gas passes through the gas transmission pipe 56 until it reaches the flame stabilizing disc 59.

[0028] The shape of the gas stirring ring 53 is set to be semicircular, the air blower 55 is fixedly penetrated through the top of the mixing cylinder 3, a hydrogen gas concentration sensor is arranged inside the burner body 1, the hydrogen gas concentration sensor includes a sensing module and a transmission module, and the transmission module is electrically connected to the electric rotating rod 510. When the hydrogen gas concentration sensor senses that the hydrogen gas concentration inside the burner body 1 is higher than a predetermined value, the hydrogen gas concentration sensor transmits a signal to the electric rotating rod 510 through the transmission module.

[0029] For example, as Figures 1 to 7 shown, the staff respectively input hydrogen gas and combustion-supporting gas into the inside of the mixing cylinder 3 through the hydrogen gas pipe 51 and the combustion-supporting gas pipe 52. At this time, the motor 4 is started, and the output end of the motor 4 rotates to drive the gas stirring ring 53 to rotate. The gas stirring ring 53 rotates to mix and stir the hydrogen gas and the combustion-supporting gas inside the mixing cylinder 3, improving the mixing uniformity of the hydrogen gas and the combustion-supporting gas, enabling the two gases to come into full contact, providing more sufficient conditions for subsequent combustion, ensuring more sufficient and stable combustion, improving the combustion efficiency, reducing the phenomenon of incomplete combustion caused by insufficient mixing, reducing energy waste and pollutant emissions. Then the mixed gas moves upward through the drying cylinder 54, and then is dried under the action of the desiccant inside the drying cylinder 54. Then the mixed gas passes through the gas transmission pipe 56 until it reaches the flame stabilizing disc 59. At this time, the ignition pipe 2 is started, and the ignition pipe 2 ignites the mixed gas inside the gas transmission pipe 56. At this time, the device operates by spraying flames through the flame stabilizing disc 59.

[0030] When the mixed gas inside the gas pipeline 56 leaks, during the operation of the detector 57, the air inside the burner body 1 will be sucked into the hydrogen concentration sensor arranged inside the burner body 1. When the hydrogen concentration sensor senses that the hydrogen concentration inside the burner body 1 is higher than the predetermined value, the hydrogen concentration sensor transmits a signal to the electric rotating rod 510 through the transmission module. The electric rotating rod 510 is activated under the action of the signal of the transmission module. The output end of the electric rotating rod 510 rotates to drive the partition plate 511 to rotate. The electric rotating rod 510 rotates to physically isolate the flame outlet of the burner body 1, achieving the isolation of the equipment when hydrogen leaks from the equipment, effectively avoiding serious safety accidents such as fires and explosions caused by hydrogen leakage, ensuring the safety of the equipment, the surrounding environment and personnel. Moreover, when the mixed gas passes through the gas pipeline 56, the cooling ring 58 will cool the mixed gas, improving the utilization rate of the gas for subsequent combustion and thus improving the combustion efficiency.

[0031] As Figures 1 to 7 shown, it shows that in another embodiment of the present invention, a drying device for drying the mixed gas inside the mixing cylinder 3 is provided on the inner wall of the mixing cylinder 3. The drying device includes a filter plate 61. The filter plate 61 is slidably installed on the inner wall of the mixing cylinder 3. The output end of the motor 4 is fixedly installed with a fixing ring 62. A stirring rod 63 passes through the surface of the fixing ring 62 in a rotating manner. A turntable 64 is fixedly installed on the circumferential surface of the stirring rod 63. The output end of the motor 4 is fixedly installed with a fixing plate 65. An inclined cutting block 66 is fixedly installed at the bottom of the fixing plate 65. A telescopic spring rod 67 is fixedly installed on the circumferential surface of the motor 4. A sleeve plate 68 is sleeved on the circumferential surface of the motor 4. A limiting plate 69 is fixedly installed on the surface of the sleeve plate 68. The limiting plate 69 releases the restriction on the hydrogen gas pipeline 51 and the combustion-supporting gas pipeline 52. At this time, hydrogen and combustion-supporting gas enter the inside of the mixing cylinder 3, realizing the discontinuous delivery of hydrogen and combustion-supporting gas. A closing plate 610 is fixedly installed inside the hydrogen gas pipeline 51. In some examples, stirring plates are arranged on the circumferential surface of the stirring rod 63. The turntable 64 contacts the circumferential surface of the fixing ring 62. The rotation of the fixing ring 62 drives the stirring rod 63 to rotate. The rotation of the stirring rod 63 drives the turntable 64 to rotate. The turntable 64 rotates with the fixing ring 62 as the center. An air outlet 1 is opened on the surface of the limiting plate 69. An air outlet 2 is opened on the closing plate 610. The air outlet 1 coincides with the air outlet 2.

[0032] The free end of the telescopic elastic rod 67 is fixedly connected to the sleeve plate 68. The surface of the inclined cutting block 66 is provided with a first arc surface for contacting and squeezing the cooling ring 58 to move downward. The first limiting plate 69 is slidably connected to the inner wall of the hydrogen gas pipe 51. The number of the first limiting plates 69 is set to two, and the two first limiting plates 69 are respectively slidably connected to the inner walls of the hydrogen gas pipe 51 and the combustion-supporting gas pipe 52. Under the action of the sleeve plate 68, the first limiting plate 69 moves downward until the air inlets coincide, and at this time, the first limiting plate 69 releases the restriction on the hydrogen gas pipe 51 and the combustion-supporting gas pipe 52.

[0033] The surface of the flame stabilizing disc 59 is provided with a limiting device for restricting the outlet of the hydrogen gas pipe 51. The limiting device includes a connecting rod 71. The connecting rod 71 is fixedly installed on the surface of the flame stabilizing disc 59. A second closing plate 72 is fixedly installed on the inner wall of the hydrogen gas pipe 51. A second limiting plate 73 is slidably installed at one end of the hydrogen gas pipe 51 close to the mixing cylinder 3. The bottom of the sleeve plate 68 is fixedly installed with a linkage rod 74. The circumferential surface of the motor 4 is fixedly installed with a cleaning ring 75. A cleaning cylinder 76 is rotatably installed on the surface of the cleaning ring 75. A roller 77 is fixedly installed on the circumferential surface of the cleaning cylinder 76. The rotation of the roller 77 drives the cleaning cylinder 76 to rotate. At the same time, the rotation of the cleaning cylinder 76 drives the brush bristles to rotate, and the rotation of the brush bristles scrapes off the dust or impurities blocked or attached to the surface of the drying cylinder 54.

[0034] The roller 77 contacts the drying cylinder 54. The circumferential surface of the cleaning cylinder 76 is provided with brush bristles. The linkage rod 74 is fixedly connected to the filter plate 61. The movement of the linkage rod 74 drives the filter plate 61 to move downward. At this time, the downward movement of the filter plate 61 shakes off the impurities or dust adsorbed in the mixed gas by moving.

[0035] For example, as Figures 1 to 7 shown, when the output end of the motor 4 rotates to drive the fixed ring 62 to rotate, the rotation of the fixed ring 62 stirs the desiccant inside the drying cylinder 54, increases the contact area between the desiccant and the mixed gas, and further improves the drying rate, enabling the mixed gas to reach the required drying degree faster, ensuring that the gas entering the combustion link is dry and pure, avoiding the influence of humid gas on the combustion effect, and at the same time preventing the humid gas from corroding the internal components of the equipment, extending the service life of the equipment. At the same time, the rotation of the fixed ring 62 drives the stirring rod 63 to rotate, and the rotation of the stirring rod 63 drives the turntable 64 to rotate. The turntable 64 rotates around the fixed ring 62 as the center. Since the turntable 64 contacts the circumferential surface of the fixed ring 62, the rotation of the turntable 64 causes it to rotate on its own under the action of the fixed ring 62. At the same time, the rotation of the turntable 64 drives the stirring rod 63 to rotate. At this time, the rotation of the stirring rod 63 drives the stirring plate to rotate, further improving the stirring and mixing effect of the desiccant. At this time, the revolution of the fixed ring 62 drives the self-rotation of the stirring rod 63, ensuring full contact between the desiccant and the mixed gas, maximizing the drying performance of the desiccant, and improving the drying efficiency and quality.

[0036] When the output end of the motor 4 rotates to drive the fixed disk 65 to rotate, the fixed disk 65 rotates to drive the inclined cutting block 66. At the same time, the inclined cutting block 66 rotates to contact and squeeze the sleeve plate 68 to move downward. The downward movement of the sleeve plate 68 drives the first limiting plate 69 to move downward. At the same time, under the action of the sleeve plate 68, the first limiting plate 69 moves downward until the air inlet coincides. At this time, the first limiting plate 69 releases the restriction on the hydrogen pipe 51 and the combustion-supporting gas pipe 52. At this time, hydrogen and combustion-supporting gas enter the interior of the mixing cylinder 3, realizing the discontinuous delivery of hydrogen and combustion-supporting gas, avoiding the continuous supply of hydrogen under abnormal or non-working conditions of the system, reducing the risk of safety accidents such as explosion and fire caused by the accumulation of hydrogen leakage, and at the same time, the discontinuous delivery of hydrogen can more flexibly adjust the hydrogen supply, enabling the burner to quickly adapt to load changes and maintain good working performance.

[0037] When the first limiting plate 69 moves downward under the action of the sleeve plate 68 to drive the connecting rod 71 to move, the downward movement of the connecting rod 71 drives the second limiting plate 73 to move. At the same time, under the action of the connecting rod 71, the second limiting plate 73 moves downward until it coincides with the opening on the surface of the closing plate 72. At this time, the hydrogen in the hydrogen pipe 51 can be transported, realizing that hydrogen can only be transported when the combustion-supporting gas channel is opened, avoiding the separate transportation of hydrogen caused by misoperation or equipment failure, thus causing potential safety hazards, further ensuring the safety and stability of equipment operation, and ensuring that hydrogen and combustion-supporting gas enter the combustion link in the correct order and conditions.

[0038] When the sleeve plate 68 moves downward under the action of the inclined cutting block 66, the movement of the sleeve plate 68 drives the linkage rod 74 to move downward. At the same time, the movement of the linkage rod 74 drives the filter plate 61 to move downward. At this time, the downward movement of the filter plate 61 shakes off the impurities or dust adsorbed in the mixed gas by moving, avoiding the influence of dust and the like adhering to the surface of the filter plate 61 on its performance of filtering the mixed gas. At the same time, the output end of the motor 4 rotates to drive the cleaning ring 75 to rotate. The rotation of the cleaning ring 75 drives the cleaning cylinder 76 to rotate around the cleaning ring 75 as the center. The rotation of the cleaning cylinder 76 drives the roller 77 to rotate. Because the roller 77 contacts the drying cylinder 54, and at the same time, the rotation of the roller 77 causes it to rotate on its own under the action of the drying cylinder 54. At this time, the rotation of the roller 77 drives the cleaning cylinder 76 to rotate. At the same time, the rotation of the cleaning cylinder 76 drives the brush bristles to rotate, and the rotation of the brush bristles scrapes off the dust or impurities blocked or attached to the surface of the drying cylinder 54, avoiding the influence on the drying efficiency of the drying cylinder 54 due to a large amount of dust or impurities being blocked, ensuring the normal functioning of the drying function of the drying device drying cylinder 54, maintaining the stable operation of the overall equipment, improving the combustion quality and equipment reliability, and at the same time reducing equipment failures and performance degradation caused by impurities and blockages.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
