Specific embodiments

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a heating furnace device for improving combustion efficiency, including a heating furnace body 1, a gas inlet pipe 6, an air inlet pipe 8 and a PLC controller 24. A combustion chamber 22 is provided inside the heating furnace body 1. A heat conduction cylinder 23 is fixedly connected to the inner top end of the heating furnace body 1, and the heat conduction cylinder 23 is located inside the combustion chamber 22. Air injection pipes 19 are uniformly and fixedly installed at the bottom end of the combustion chamber 22. Air spray heads 20 are uniformly and fixedly installed at the top ends of the air injection pipes 19. A second filter screen 18 is fixedly installed above the air spray heads 20 inside the combustion chamber 22 for secondary filtration, and the second filter screen 18 can disperse the air sprayed from the air injection pipes 19 so that the air enters the combustion chamber 22 evenly. Gas injection pipes 16 are uniformly and fixedly installed above the second filter screen 18 inside the combustion chamber 22. Gas spray heads 17 are uniformly and fixedly installed at the top ends of the gas injection pipes 16. Oxygen content sensors 21 are uniformly and fixedly installed inside the combustion chamber 22.

[0021] On both sides of the heating furnace body 1, a first gas delivery pipe 12, a first air delivery pipe 14, a second gas delivery pipe 13, and a second air delivery pipe 15 are respectively provided. One end of the gas injection pipe 16 is fixedly installed on the first gas delivery pipe 12, and the other end of the gas injection pipe 16 is fixedly installed on the second gas delivery pipe 13. One end of the air injection pipe 19 is fixedly installed on the first air delivery pipe 14, and the other end of the air injection pipe 19 is fixedly installed on the second air delivery pipe 15.

[0022] The gas inlet pipe 6 and the air inlet pipe 8 are both arranged at one end of the heating furnace body 1. The ends of the first gas delivery pipe 12 and the second gas delivery pipe 13 far from the gas injection pipe 16 are respectively fixedly installed at the end of the gas inlet pipe 6 close to the heating furnace body 1. The ends of the first air delivery pipe 14 and the second air delivery pipe 15 far from the air injection pipe 19 are respectively fixedly installed at the end of the air inlet pipe 8 close to the heating furnace body 1. The end of the gas injection pipe 16 farthest from the gas inlet pipe 6 close to the first gas delivery pipe 12 is connected to the tail end of the first gas delivery pipe 12. The end of the gas injection pipe 16 closest to the gas inlet pipe 6 close to the second gas delivery pipe 13 is connected to the tail end of the second gas delivery pipe 13. The end of the air injection pipe 19 farthest from the air inlet pipe 8 close to the first air delivery pipe 14 is connected to the tail end of the first air delivery pipe 14. The end of the air injection pipe 19 closest to the air inlet pipe 8 close to the second air delivery pipe 15 is connected to the tail end of the second air delivery pipe 15. The air inlet pipe 8 divides the air through shunt and delivers the air to the air injection pipes 19 through the first air delivery pipe 14 and the second air delivery pipe 15 respectively. Moreover, due to the reverse connection of the air injection pipes 19 with the first air delivery pipe 14 and the second air delivery pipe 15, the air flow in the uniformly distributed air injection pipes 19 is relatively uniform.

[0023] At the top end of the gas inlet pipe 6, a first flow sensor 7 is fixedly installed to monitor the gas flow in real time through the first flow sensor 7. At the top end of the air inlet pipe 8 near one end of the heating furnace body 1, a second flow sensor 9 is fixedly installed to monitor the air flow in real time through the second flow sensor 9. Inside the air inlet pipe 8 at the end far from the heating furnace body 1, a fan 10 is fixedly installed to convey air into the air inlet pipe 8 through the fan 10. At the end of the air inlet pipe 8 near the fan 10, a first filter screen 11 is fixedly installed. The first filter screen 11 filters out impurity particles in the air to reduce the influence of impurities on combustion. At the top of the heating furnace body 1, a smoke exhaust pipe 2 is fixedly installed, and the smoke exhaust pipe 2 is communicated with the combustion chamber 22. Inside the heat conduction cylinder 23, a storage rack 5 is movably inserted. One end of the storage rack 5 far from the gas inlet pipe 6 is fixedly connected with a sealing door 3. At one end of the heating furnace body 1 near the sealing door 3, an inspection cover 4 is fixedly installed, and the inspection cover 4 is located below the sealing door 3 to facilitate later maintenance through the inspection cover 4.

[0024] The PLC controller 24 is respectively wired and electrically connected to the first flow sensor 7, the second flow sensor 9, the fan 10 and the oxygen content sensor 21. Through the PLC controller 24, the proportion of oxygen and gas can be automatically adjusted, thereby improving the gas combustion efficiency.

[0025] Working principle: During use, first set the control program through the PLC controller 24 according to the type and purity of the gas, and connect the gas inlet pipe 6 to the output end of the gas pipeline. When heating is enabled, the gas is respectively transported to the first gas delivery pipe 12 and the second gas delivery pipe 13 through the gas inlet pipe 6. The first gas delivery pipe 12 and the second gas delivery pipe 13 respectively transport the gas to the inside of the gas injection pipe 16 and spray it inside the combustion chamber 22 through the gas nozzle 17. At the same time, the PLC controller 24 controls the fan 10 to start. The fan 10 transports the external air to the first air delivery pipe 14 and the second air delivery pipe 15 respectively through the air inlet pipe 8. The first air delivery pipe 14 and the second air delivery pipe 15 respectively transport the air to the inside of the air injection pipe 19 and spray it inside the combustion chamber 22 through the air nozzle 20. When the air enters the air inlet pipe 8, impurities in the air are filtered by the first filter screen 11, and the air sprayed through the air nozzle 20 blows on the bottom end of the second filter screen 18 for secondary filtration, reducing the influence of air impurities on gas combustion. At the same time, the air can be evenly dispersed into the combustion chamber 22 through the second filter screen 18. The first flow sensor 7 and the second flow sensor 9 respectively monitor the flow rates of the gas and the air in real time and transmit the monitored data to the PLC controller 24 in real time. The PLC controller 24 adjusts the power of the fan 10 according to the preset program, thereby adjusting the air flow rate so that the ratio of oxygen and gas entering the combustion chamber 22 reaches the optimal ratio. The oxygen content sensor 21 monitors the oxygen content inside the combustion chamber 22 in real time. When the oxygen content fluctuates greatly and exceeds the optimal threshold range of the oxygen and gas ratio, the PLC controller 24 controls the fan 10 to adjust the power to regulate the oxygen concentration inside the combustion chamber 22.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
