Description

Technical Field

[0001] This utility model relates to the technical field of waste incineration equipment, and in particular to a high-efficiency and energy-saving waste incinerator burner. Background Technology

[0002] In the waste incineration process, the burner is a crucial core component, and its performance directly affects the combustion efficiency, energy utilization efficiency, and the amount of pollutants generated. Currently, commercially available waste incinerator burners suffer from numerous problems. On the one hand, poor fuel-air mixing leads to incomplete combustion, resulting not only in energy waste but also a large amount of unburned pollutants. On the other hand, existing burner structures are difficult to adjust flexibly according to the characteristics of different wastes and combustion conditions, failing to meet diverse combustion requirements. Furthermore, the flame shape and combustion range of the burner are difficult to control precisely, affecting the stability and uniformity of combustion, further reducing the effectiveness of waste incineration.

[0003] Therefore, this application provides a high-efficiency and energy-saving waste incinerator burner to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a high-efficiency and energy-saving waste incinerator burner to solve the problems of insufficient fuel-air mixing and difficulty in flexibly adjusting the combustion state in existing waste incinerator burners, so as to achieve efficient and complete combustion of waste, improve energy utilization efficiency, and reduce pollutant emissions.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-efficiency and energy-saving waste incinerator burner, comprising a burner body, a motor on the left side of the burner body for driving the movement of internal components, an air inlet on the right side of the burner body, a flame tube at the front of the burner body, a fuel pipe for conveying fuel inside the flame tube, an ignition head at the front outlet of the flame tube, an ignition wire connected to the rear of the ignition head, the ignition head generating an electric spark under the action of the ignition wire to ignite the fuel, and the fuel pipe and the ignition wire passing through the burner body for connection to an external fuel supply system and ignition control system;

[0006] The front outlet of the flame tube is provided with an installation ring, and a bracket is arranged in a ring array inside the installation ring. A bolt seat is provided at the junction center of the brackets. An adjusting bolt is threadedly connected to the bolt seat. A connecting rod is hinged to the rear end of the adjusting bolt. There are multiple sets of connecting rods, and the other end of the connecting rod is slidably connected to the bracket. Each connecting rod is provided with a guide plate. By using the adjusting bolt to change the position and angle of the guide plate, the direction and range of fuel injection can be adjusted to adapt to different combustion requirements.

[0007] The front end of the flame tube is fitted with a flow guide, the front part of which is inwardly curved to guide the airflow and form a specific airflow pattern at the outlet of the flame tube, which helps to promote more complete mixing of fuel and air and improve combustion efficiency.

[0008] Preferably, the rear end of the adjusting plug is provided with a guide cap, the rear part of which is conical, and the front end of the fuel pipe is provided with a nozzle, the nozzle being positioned corresponding to the guide cap. The conical structure of the guide cap can guide and disperse the fuel sprayed from the nozzle, making the fuel more evenly distributed in the outlet area of ​​the flame tube, further optimizing the fuel spraying effect and improving the uniformity of fuel-air mixing.

[0009] Preferably, the connecting rod is hinged to the front side of the guide cap, and the bracket is provided with a guide groove. The end of the connecting rod is slidably connected in the guide groove, which makes the connecting rod more stable during sliding and can more accurately transmit the movement of the adjusting bolt to the guide plate, ensuring the accuracy and reliability of the adjustment.

[0010] Preferably, the guide plate is fan-shaped and can block the front outlet of the flame tube. The adjacent guide plates are staggered, which allows for flexible adjustment of the fuel injection range and direction by changing the position and angle of the guide plates. The staggered guide plates can further optimize the fuel dispersion effect and avoid motion interference, so that the fuel forms a more reasonable distribution at the outlet of the flame tube, thereby improving the completeness of combustion.

[0011] Preferably, the guide plate is provided with air guide vanes, which are arranged in multiple groups and evenly. Each group of air guide vanes has an air guide hole on its rear side, which can guide and distribute the air more precisely, so that the air and fuel can be mixed more efficiently at the outlet of the flame tube, thereby further improving the combustion efficiency and reducing energy consumption.

[0012] Preferably, the front end of the adjusting bolt is provided with a butterfly cap, which makes it easy for the operator to rotate the adjusting bolt, thereby improving the convenience of adjustment and the comfort of operation.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Improve combustion efficiency: By adjusting the bolt, connecting rod and guide plate, the direction and range of fuel injection can be flexibly adjusted.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figure 1-6 The high-efficiency and energy-saving waste incinerator burner shown includes a burner body 1, a motor 10 on the left side of the burner body 1, an air inlet chamber 11 on the right side of the burner body 1, a flame tube 2 at the front of the burner body 1, a fuel pipe 12 for conveying fuel inside the flame tube 2, an ignition head 15 at the front outlet of the flame tube 2, and an ignition wire 14 connected to the rear of the ignition head 15. The fuel pipe 12 and the ignition wire 14 pass through the burner body 1.

[0027] The front outlet of the flame tube 2 is provided with an installation ring 20. There are six sets of brackets 21 arranged in a ring inside the installation ring 20. A bolt seat 22 is provided at the junction center of the brackets 21. An adjusting bolt 4 is threadedly connected to the bolt seat 22. Six sets of connecting rods 50 are hinged to the rear end of the adjusting bolt 4. The other end of the connecting rod 50 is slidably connected to the bracket 21. Each connecting rod 50 is provided with a guide plate 5.

[0028] The front end of the flamethrower tube 2 is fitted with a flow guide 3, and the front part of the flow guide 3 is recessed.

[0029] As one implementation method in this embodiment, in order to guide and disperse the fuel sprayed from the nozzle 13, such as... Figure 4 , Figure 5 As shown, the rear end of the adjusting plug 4 is provided with a guide cap 40, the rear part of the guide cap 40 is conical, and the front end of the fuel pipe 12 is provided with a nozzle 13, the nozzle 13 is positioned corresponding to the guide cap 40.

[0030] As one implementation method in this embodiment, to ensure the stability and reliability of the linkage 50's movement, such as Figure 4 , Figure 5 As shown, a connecting rod 50 is hinged to the front side of the guide cap 40, and a guide groove is provided on the bracket 21. The end of the connecting rod 50 is slidably connected in the guide groove.

[0031] As one implementation method in this embodiment, to ensure the effectiveness of the guide plate 5 in adjusting the fuel injection range and angle, and to avoid motion interference, such as Figure 5 , Figure 6 As shown, the guide plate 5 is fan-shaped and can block the front outlet of the flame tube 2. The adjacent guide plates 5 are staggered.

[0032] As one implementation method in this embodiment, to improve the mixing level of fuel and air and increase combustion efficiency, such as... Figure 6 As shown, multiple sets of air guide plates 51 are evenly arranged on the guide plate 5, and each set of air guide plates 51 has an air guide hole 52 on its rear side.

[0033] As one implementation method in this embodiment, to facilitate manual rotation of the adjusting bolt 4, such as Figure 5 As shown, the front end of the adjusting plug 4 is equipped with a butterfly cap.

[0034] The working principle of this practical application is as follows: In actual use, firstly, the burner body 1 is installed on the waste incinerator, and the fuel pipe 12 is connected to the external fuel supply system, and the ignition wire 14 is connected to the ignition control system to ensure normal fuel supply and ignition function. Then, according to the characteristics of the waste to be treated and the expected combustion conditions, the operator can move the adjusting plug 4 back and forth on the plug seat 22 by rotating the butterfly cap at the front end of the adjusting plug 4.

[0035] When the adjusting bolt 4 moves forward, the guide cap 40 moves forward accordingly. The connecting rod 50, which is hinged to the front side of the guide cap 40, slides in the guide groove of the bracket 21, causing the outer side of the guide plate 5 to move away from the center of the flame tube 2. At this time, the area of ​​the guide plate 5 blocking the outlet of the flame tube 2 increases, the direct injection range of the fuel decreases, and the fuel is guided by the air guide plate 51 under the blowing of the air and sprayed out from the air guide hole 52. The fuel and air are mixed more fully, which is suitable for processing waste with low calorific value that requires a larger combustion space, and ensures that the fuel can fully contact the air and burn.

[0036] Conversely, when the adjusting bolt 4 moves backward, the guide plate 5 moves towards the center of the flame tube 2, the obstruction area of ​​the flame tube 2 outlet decreases, and some fuel can be ejected outward along the mounting ring 20 with the air, expanding the direct injection range of the fuel. This is suitable for processing waste with high calorific value and fast combustion speed, and enables the fuel to burn quickly and completely in a small area.

[0037] During combustion, the motor 10 starts, and the burner body 1 draws air in from the air inlet chamber 11. The air then mixes with the fuel ejected from the nozzle 13 in the burner tube 2. During fuel injection, the fuel ejected from the nozzle 13 is guided and dispersed by the conical structure of the guide cap 40, and is evenly distributed in the outlet area of ​​the burner tube 2. It mixes thoroughly with the air introduced from the air inlet chamber 11, and under the action of the guide shroud 3, forms a specific airflow pattern towards the center. Finally, the ignition head 15 generates an electric spark under the action of the ignition wire 14, igniting the mixed fuel and air, thus achieving efficient combustion of waste.

[0039] Components not described in detail in this article are existing technologies.
