Description

Technical Field

[0001] This utility model relates to the field of burner cooling, specifically to a waste incinerator burner cooling air device. Background Technology

[0002] The waste inside the waste incinerator needs to reach a certain temperature to begin combustion. Therefore, when the waste incinerator starts up, it uses a burner to burn fuels such as oil and gas to provide a heat source for the waste combustion and bring it to the ignition temperature. Once the temperature inside the waste incinerator reaches a certain condition, the burner will stop operating. However, because the burner is fixed to the waste incinerator, it will be subject to backheating from the high temperature inside the waste incinerator during normal operation. This poses a safety hazard to the burner, increases the failure rate of the electrical components in the burner, and reduces overall reliability. Utility Model Content

[0003] The purpose of this utility model is to provide a cooling air device for a waste incinerator burner, in order to solve the technical problem mentioned above that the burner is subjected to backheating from the high temperature inside the waste incinerator, which increases the failure rate of electrical components in the burner body and reduces the overall reliability.

[0004] To solve the above-mentioned technical problems, this utility model provides a waste incinerator burner cooling air device, which includes a burner and a cooling air component. The cooling air component is installed at the end of the burner and includes an air inlet, an annular pipe and an air outlet. The air inlet is provided at the top of the cooling air component and is connected to the annular pipe. Several air outlets are provided on the inner side of the annular pipe and the air outlets are at a certain angle to the burner.

[0005] Furthermore, it also includes a burner support, the burner is mounted on the burner support, and the burner support is provided with an annular fixing frame along the outer edge of the burner, on which a cooling air component is fixedly connected.

[0006] Furthermore, the axial angle between the air outlet and the burner is 60°-80°.

[0007] Furthermore, there are at least 16 air outlets, the air outlets are equidistant from each other, and the air outlets are arranged in a circular pattern.

[0008] Furthermore, the inner diameter of the cooling air component is larger than the outer diameter of the burner end.

[0009] Furthermore, a furnace wall is provided inside the burner support, and the furnace wall includes refractory castable and insulating castable.

[0010] Furthermore, the furnace wall is tapered at the end of the burner.

[0011] The beneficial effects of this invention are as follows: Compared with existing technologies, the cooling air device for a waste incinerator burner introduces cold air through an air inlet.

Obviously, the described embodiments are only one embodiment 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.

[0017] To make the objectives, technical solutions and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0018] In the following description, references to "an embodiment," "an embodiment," "an example," "example," etc., indicate that the described embodiment or example may include a particular feature, structure, characteristic, property, element, or limitation, but not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Furthermore, the repeated use of the phrase "an embodiment according to this application," while possibly referring to the same embodiment, does not necessarily refer to the same embodiment.

[0019] In this embodiment: as Figure 1As shown, the device includes a burner 1 and a cooling air component 7. The cooling air component 7 is installed at the end of the burner 1. The cooling air component 7 includes an air inlet 3, an annular pipe 4, and an air outlet 6. The air inlet 3 is located at the top of the cooling air component 7 and is connected to the annular pipe 4. Several air outlets 6 are provided on the inner side of the annular pipe 4. The air outlets 6 are at a certain angle to the burner 1. By installing the cooling air component 7 at the end of the burner 1, a compact design layout is achieved, ensuring that the cooling air can directly act on the surface of the burner 1, thereby improving the cooling efficiency, effectively reducing the operating temperature of the burner 1, and improving its service life and working efficiency.

[0020] It also includes a burner support 2, on which the burner 1 is mounted. The burner support 2 has an annular fixing frame 5 along the outer edge of the burner 1. The cooling air component 7 is fixedly connected to the annular fixing frame 5. The annular fixing frame 5 on the burner support 2 ensures that the cooling air component 7 is securely connected to the burner 1, preventing loosening or displacement during operation and ensuring the overall stability of the system.

[0021] The axial angle between the air outlet 6 and the burner 1 is 60°-80°. The design of the annular pipe 4 of the cooling air component 7 and the specific angle setting of the air outlet 6 ensure that the cold air can be evenly distributed around the burner 1, optimize the coverage and cooling effect of the cooling air, reduce the risk of local overheating, and enhance the cooling effect.

[0022] There are at least 16 air outlets 6. Specifically, in this embodiment, the most preferred number of air outlets 6 is 24. The air outlets 6 are evenly spaced and arranged in a circle. The circular arrangement and even spacing of the air outlets 6 make the cooling air flow smoother. The evenly spaced and circularly arranged air outlets 6 design ensures the uniform distribution of cooling air, eliminates the problem of uneven cooling, improves the temperature control effect of each part of the burner 1, and further improves the cooling efficiency.

[0023] The inner diameter of the cooling air component 7 is larger than the outer diameter of the burner 1 end. This design provides sufficient space to ensure the free flow of cold air, avoids airflow obstruction, and enhances cooling efficiency.

[0024] A furnace wall 21 is installed inside the burner support 2. The furnace wall 21 includes refractory castable and insulating castable. The furnace wall 21 installed on the burner support 2 further improves the thermal stability and safety of the entire system through the combination of refractory castable and insulating castable.

[0025] The furnace wall 21 is tapered at the end of the burner 1. The tapered furnace wall 21 design helps to guide the hot airflow, reduce heat loss, improve combustion efficiency, and enhance the stability and durability of the structure.

[0026] Working principle: Cooling air component 7 introduces cold air through air inlet 3. After entering the annular pipe 4, the air is evenly sprayed out through multiple air outlets 6. Since the axial angle between the air outlets 6 and the burner 1 is 60°-80°, the cold air can cover the surface of the burner 1 at the optimal angle, forming a uniform cooling airflow. This design effectively reduces the surface temperature of the burner 1 and prevents overheating damage.

[0027] Installation process: Fix the burner bracket 2 in the predetermined position, install the furnace wall 21 inside the burner bracket 2 using refractory castable and insulating castable, the furnace wall 21 is tapered 22 along the end of the burner 1, install the burner 1 on the burner bracket 2, the air outlet 6 of the cooling air component 7 is at an angle between 60° and 80° with the axial direction of the burner 1, and fix the cooling air component 7 on the burner bracket 2 by the annular fixing bracket 5.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
