Description

Technical Field

[0001] This utility model relates to the field of low-NOx burner equipment, specifically a hydrogen-assisted low-NOx burner. Background Technology

[0002] Low-NOx burners are burners that emit low levels of nitrogen during fuel combustion, reducing nitrogen oxide emissions. However, existing ultra-low-NOx burners do not recycle the flue gas completely, which easily produces more combustion exhaust gas. At the same time, incomplete flue gas combustion reduces the calorific value of the combustion and lowers the combustion ratio of the raw materials.

[0003] According to the patent document CN209763065U, a hydrogen-assisted low-NOx burner device includes a main body, a front plate, a control panel, a protective shell, a fixing pipe, a flue pipe, a blower, a top cover, and a water outlet pipe. The main body is installed inside the protective shell. The control panel for controlling the burner is fixedly connected to the front of the protective shell with screws. A switch is installed on the side of the control panel, and user operation buttons are provided on the surface of the control panel. The front plate for protecting the control panel is snapped into the front of the protective shell. A blower for promoting airflow is installed at the bottom right side of the protective shell. In use, this technical solution utilizes the pressure difference between the flue pipe and the air inlet to generate a pressure head that draws back some of the flue gas flowing out of the flue pipe and into the burner, where it mixes with air for combustion. Through flue gas recirculation, the combustion of hydrogen is fully utilized. The combustion flue gas has a large heat capacity, a lower combustion temperature, and less nitrogen oxides, ensuring complete combustion of fuel. However, although this technical solution achieves the recycling of flue gas, it cannot filter impurities in the flue gas during the recirculation process, which is inconvenient in use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hydrogen-assisted low-NOx burner to solve the problems mentioned in the background technology. This utility model has a novel structure. In use, the flue gas is drawn into the mixing seat by the connecting pipe. Driven by the stirring wheel inside the mixing seat, it is blown downward into the fixed pipe. The gas is filtered through the filter plate. At the same time, the stirring wheel cleans the surface of the filter plate by scraping.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a hydrogen-assisted low-NOx burner, comprising a fixed base, a support base fixed on the fixed base, a burner body fixed on the top of the support base, a drive motor fixedly installed on one side of the burner body, a feed pipe fixedly installed on the other side of the burner body, a fixed pipe fixed on the burner body, a fixed cover fixed at one end of the fixed pipe, a connecting pipe fixed on the fixed cover, a mixing seat fixed at one end of the connecting pipe, and the mixing seat fixedly installed on the fixed pipe.

[0006] Furthermore, a support pipe and a slag discharge port are respectively installed on the side of the mixing seat, a sealing cover is rotatably installed on the slag discharge port, and a movable pipe is movably installed inside the fixed pipe.

[0007] Furthermore, a fixing groove is provided on the movable tube, and an ignition mechanism is movably installed inside the fixing groove. The ignition mechanism is fixedly installed on the inner wall of the fixing tube.

[0008] Furthermore, a ring tube is fixed on the inner wall of the fixing cover, and an opening is made in the ring tube. The ring tube is fixedly installed at one end of the connecting tube.

[0009] Furthermore, a support frame is fixedly installed on the fixed base, and the support frame is fixedly installed at the bottom of the fixed tube.

[0010] Furthermore, a rotating motor is fixedly installed on the mixing seat, and a stirring wheel is installed on the rotating motor. The stirring wheel is rotatably installed inside the mixing seat.

[0011] Furthermore, a filter plate is fixedly installed between the mixing seat and the fixed pipe, and the stirring wheel is rotatably installed on the top of the filter plate.

[0012] Furthermore, a pressure wheel is rotatably mounted inside the burner body, and the pressure wheel is mounted on the drive motor via an output shaft. A fixing hole is provided on the fixing base.

[0013] The beneficial effects of this utility model are:

[0014] This hydrogen-assisted low-NOx burner operates by drawing flue gas through a connecting pipe into a mixing chamber. The gas is then blown downwards into a fixed pipe by a stirring wheel inside the mixing chamber. The gas is filtered through a filter plate, and the stirring wheel simultaneously cleans the surface of the filter plate by scraping it.

[0015] This hydrogen-assisted low-NOx burner has a connecting pipe that works in conjunction with a ring pipe. By using openings at different positions on the ring pipe, it extracts flue gas, thus avoiding the impact of flue gas moving outward. The movable pipe moves inside the fixed pipe later to adjust the position of the combustion exhaust hot spot to meet the needs of different situations. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a hydrogen-assisted combustion low-NOx burner, including a fixed base 1, a support base 3 fixed on the fixed base 1, a burner body 4 fixed on the top of the support base 3, a drive motor 5 fixedly installed on one side of the burner body 4, a feed pipe 6 fixedly installed on the other side of the burner body 4, a fixed pipe 7 fixed on the burner body 4, a fixed cover 11 fixed at one end of the fixed pipe 7, a connecting pipe 10 fixed on the fixed cover 11, a mixing seat 8 fixed at one end of the connecting pipe 10, the mixing seat 8 fixedly installed on the fixed pipe 7, a support pipe 9 and a slag discharge port 17 respectively installed on the side of the mixing seat 8, a sealing cover rotatably installed on the slag discharge port 17, a movable pipe 12 movably installed inside the fixed pipe 7, and the drive motor 5 drives a pressure wheel to drive gas into the fixed pipe 7 for moving combustion.

[0023] In this embodiment, a fixing groove 22 is provided on the movable tube 12, and an ignition mechanism 20 is movably installed inside the fixing groove 22. The ignition mechanism 20 is fixedly installed on the inner wall of the fixing tube 7. An annular tube 13 is fixed on the inner wall of the fixing cover 11. An opening 15 is provided on the annular tube 13. The annular tube 13 is fixedly installed at one end of the connecting tube 10. A support frame 16 is fixedly installed on the fixing seat 1. The support frame 16 is fixedly installed at the bottom of the fixing tube 7. The annular tube 13 extracts flue gas from different positions through the opening 15.

[0024] In this embodiment, a rotating motor 19 is fixedly installed on the mixing seat 8, and an agitator 18 is installed on the rotating motor 19. The agitator 18 is rotatably installed inside the mixing seat 8. A filter plate 21 is fixedly installed between the mixing seat 8 and the fixed pipe 7. The agitator 18 is rotatably installed on the top of the filter plate 21. A pressure roller is rotatably installed inside the burner body 4. The pressure roller is installed on the drive motor 5 through the output shaft. A fixing hole 2 is opened on the fixed seat 1. Air or hydrogen is introduced later through the support pipe 9. After the hydrogen comes into contact with and mixes with the flue gas inside the mixing seat 8, it re-enters the fixed pipe 7 and the movable pipe 12 for complete combustion.

[0025] In use, the fixed base 1 is fixedly installed in the operating position through the fixed hole 2. The movable tube 12 slides inside the fixed tube 7. The movable tube 12 slides horizontally through the ignition mechanism 20. During horizontal sliding, the rotation of the movable tube 12 is avoided. After the movable tube 12 is adjusted, the feed tube 6 is brought into contact with the burning material. The material is fed into the burner body 4 through the feed tube 6. While the drive motor 5 drives the pressure wheel to rotate, it pushes the fuel into the fixed tube 7 and the movable tube 12. The ignition switch is turned on to ignite the fuel. After ignition, the flame leaks out from one end of the movable tube 12 and burns. The flue gas produced by combustion stays inside the fixed cover 11. The rotating motor 19 is started to drive the stirring wheel 18 to rotate. 18 generates suction, which is transmitted to the inside of the ring pipe 13 through the connecting pipe 10. The flue gas is extracted through the opening 15 on the ring pipe 13. After the flue gas enters the mixing seat 8, air or hydrogen enters through the support pipe 9. The hydrogen mixes with the flue gas inside the mixing seat 8 and then re-enters the fixed pipe 7 and the movable pipe 12 for complete combustion, making full use of the combustion of hydrogen. The combustion flue gas has a large heat capacity, a lower combustion temperature, and less nitrogen oxides, ensuring complete combustion of fuel. Before the flue gas enters the fixed pipe 7, it is filtered by the filter plate 21 to prevent impurities from re-entering the movable pipe 12 and causing damage. Later, the support pipe 9 is closed and the slag discharge port 17 is opened. The rotation of the stirring wheel 18 pushes the impurities outward and discharges them for cleaning.
