Description

Technical Field

[0002] Municipal waste incineration technology is gaining increasing attention in my country for its harmlessness, volume reduction, and resource utilization. However, domestic waste has a low calorific value and complex composition, primarily consisting of kitchen waste, low combustibles, and high water content. This far from meeting the required incinerator temperature. Furthermore, due to the large fluctuations in waste calorific value, incinerators struggle to maintain a constant incinerator temperature above 850°C, making it difficult to ensure dioxin decomposition and combustion stability.

[0003] For example, the publication number "CN117869898A" is named a garbage fly ash melting treatment device and treatment method, in which the fuel is cracked and burned by the igniter in the burner, and then further burned in the secondary burner to meet the melting treatment requirements of the garbage fly ash. The setting of the first feed port and the second feed port facilitates the addition of fuel at any time, thereby being able to control the combustion temperature. The second flame outlet provides a melting flame for the melting furnace. However, in the existing garbage fly ash melting treatment device and treatment method, an ignition and flame-retardant burner is required to complete the ignition and combustion of the fuel. In actual use, the burner is installed inside the garbage incinerator using an upper suspension fixing method. However, the suspended installation method causes the burner to be only fixed horizontally on the inner wall of the garbage incinerator, and the installation location and installation direction cannot be adjusted according to the type of garbage incinerator. This makes the installation and use of the burner easily restricted by spatial position, which is inconvenient for the installation and fixation of the burner. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] See also Figure 1-5 : In this embodiment, an ignition and combustion-supporting device for a waste incinerator includes a waste incinerator furnace wall 1 and an ignition burner body 2. The ignition burner body 2 is movably connected to the side wall of the waste incinerator furnace wall 1. An ignition burner positioning and mounting structure 3 is provided on the outside of the waste incinerator furnace wall 1. A burner fixing structure 4 is provided on the outside of the ignition burner body 2. An auxiliary support and reinforcement structure 5 is provided under the ignition burner body 2.

[0022] The ignition burner positioning and mounting structure 3 includes embedded parts 31 and a connecting frame 35. The two embedded parts 31 are fixedly mounted on the outer wall of the waste incinerator furnace wall 1. The other side of the two embedded parts 31 is fixedly connected to a fixing block 32. The embedded parts 31 are made of high-temperature resistant metal carbon steel material. The embedded parts 31 can be lifted and fixed on the waste incinerator furnace wall 1 where the ignition burner needs to be installed by screws or riveting welding. The other end of the two fixing blocks 32 is fixedly connected to two positioning blocks 33.

[0023] The fixing block 32 welds the two positioning blocks 33 to the outside of the embedded part 31. The side walls of the two positioning blocks 33 are fixedly connected with a connecting frame 35. Two connecting frames 35 extend from the rear side of the positioning frame 33. The other side of the connecting frame 35 is fixed with two positioning blocks 33. In this way, the inner sides of the two opposing positioning blocks 33 are fixedly connected with the ignition burner body 2 that can be installed and clamped. The other ends of the two connecting frames 35 are fixedly connected with another two positioning blocks 33. The inner sides of the multiple positioning blocks 33 are fixedly connected with two positioning rings 34.

[0024] The burner fixing structure 4 includes an extrusion plate 41 and a reserved hole 46. Multiple extrusion plates 41 are movably connected to both sides of the outer wall of the ignition burner body 2. The other ends of the multiple extrusion plates 41 are fixedly connected with stud bolts 43. The ends of the multiple stud bolts 43 pass through the inner side of the positioning block 33. The threads at both ends of the stud bolts 43 are opposite. The threads at the lower end of the stud bolts 43 can be connected to the side wall threads of the positioning ring 34. In this way, when the stud bolts 43 are screwed, the lower end threads can drive the multiple extrusion plates 41 to move closer to the outer wall of the ignition burner body 2 inside the positioning ring 34. The outer sides of the lower ends of the multiple stud bolts 43 are threadedly connected with multiple first nuts 44, and the outer sides of the top ends of the multiple stud bolts 43 are threadedly connected with multiple second nuts 45. The reserved holes 46 are fixedly opened on the inner side of the connecting frame 35.

[0025] There is a tight connection layer 42 between the multiple extrusion plates 41 and the outer wall of the ignition burner body 2. The fitting layer 42 is made of a stainless steel plate with many lines that can press the ignition burner body 2 by friction. The multiple inward extrusion plates 41 can firmly clamp the ignition burner body 2 to the inner side of the positioning ring 34. The side walls of the multiple first nuts 44 are tightly pressed against the inside of the positioning ring 34. The outer walls of the multiple second nuts 45 are tightly pressed against the outer wall of the positioning block 33. The first nuts 44 are sleeved on the outer side of the threads below the multiple stud bolts 43. The second nuts 45 are tightly pressed against the outer wall of the positioning block 33. The nut 45 is sleeved on the outer side of the threads above the multiple stud bolts 443, and the first nut 44 and the second nut 45 are rotated in opposite directions. The first nut 44 and the second nut 45 are respectively pressed against the outer side of the positioning block 33 and the inner side of the positioning ring 43, which can lock the position of the stud bolts 43 so that both sides of the stud bolts 43 are restricted and not easy to loosen. The two positioning rings 34 are arranged parallel to each other, and the other ends of the two fixing blocks 32 are fixedly connected to the two ends of the positioning ring 34. The lower side of the reserved hole 46 is arranged opposite to the feed port of the ignition burner body 2;

[0026] The ends of the multiple stud bolts 43 pass through the inner side of the positioning block 33, and the threads at both ends of the stud bolts 43 are opposite. The threads at the lower ends of the stud bolts 43 can be connected with the threads on the side wall of the positioning ring 34. In this way, when the stud bolts 43 are screwed, the threads at the lower ends can drive the multiple extrusion plates 41 to move closer to the outer wall of the ignition burner body 2 inside the positioning ring 34. The first nut 44 is sleeved on the outer side of the threads below the multiple stud bolts 43, and the second nut 45 is sleeved on the outer side of the threads above the multiple stud bolts 443. The first nut 44 is rotated in the opposite direction. And the second nut 45, the first nut 44 and the second nut 45 are respectively pressed against the outside of the positioning block 33 and the inside of the positioning ring 43, which can lock the position of the stud bolt 43, so that both sides of the stud bolt 43 are restricted and not easy to loosen. The embedded parts cooperate with the outer side to tighten the installation structure of the ignition burner body 2, so that the ignition burner body 2 can be installed wherever the embedded parts are installed. Compared with the suspended installation method, the installation position is wider and less likely to be restricted, which improves the installation and fixing effect of the ignition and combustion-supporting device for the waste incinerator.

[0027] Working principle:

[0028] When using the ignition and combustion-supporting device for the garbage incinerator, the ignition and combustion-supporting device for the garbage incinerator is installed inside the garbage incinerator, which can ignite the incinerator and provide sufficient flame to complete the garbage incineration process;

[0029] The specific structure of the ignition burner body 2 is the same as the disclosed structure of a waste fly ash melting treatment device and treatment method with publication number CN117869898A. The ignition burner body 2 consists of an igniter, a burner, a heating core and a flame straightening assembly. The burner can melt the discarded waste fly ash for recycling, which can reduce pollution to the environment and alleviate the discharge pressure of the waste fly ash. The igniter in the burner cracks and burns the fuel, and then further burns it in the secondary burner to meet the melting treatment requirements of the waste fly ash. The first feed port and the second feed port are arranged to facilitate the addition of fuel at any time, thereby being able to control the combustion temperature. The second flame outlet provides a melting flame for the melting furnace;

[0030] Then the induction coil on the igniter quickly heats the heat storage layer and the heating core through medium frequency induction, which can quickly heat the heating core from room temperature to above 800℃. The heating core uses a spiral blade structure to greatly increase the residence time of the fuel in the heating core, which is about several times the residence time of the DC type. It can greatly reduce the size of the equipment and at the same time ensure the heat exchange area of the fuel in the heating core, so that the fuel can be fully cracked into combustible gas, thereby achieving the purpose of igniting the fuel. In addition, by adjusting the stability or length of the heating core, different fuels can be ignited to meet the needs of different fuels.

[0031] The heating core is designed as a structure with spiral blades fixed outside a hollow circular tube. When in use, the air and fuel mixture enters the igniter from the first feed port, with most of the mixture entering from the spiral pulverized coal channel and a small part of the mixture entering from the circular tube. The speed in the circular tube is fast, while the flow speed in the spiral pulverized coal channel is relatively slow. In this way, a certain negative pressure area is formed at the outlet of the heating core, which reduces the resistance at the outlet of the spiral pulverized coal channel and facilitates the smooth passage of the mixture in the spiral pulverized coal channel.

[0032] A flame straightening assembly is provided to guide and straighten the high-speed swirl flame at the first flame outlet, so that the flame is output at high speed along an axial straight line, which greatly increases the length of the flame output. The straightened flame can smoothly enter the interior of the secondary burner, thereby improving the combustion effect in the secondary burner. The specific working principle and working process of the ignition burner body 2 are the same as those of the publication number CN117869898A;

[0033] The ends of the multiple stud bolts 43 pass through the inner side of the positioning block 33, and the threads at both ends of the stud bolts 43 are opposite. The threads at the lower ends of the stud bolts 43 can be connected with the threads of the side wall of the positioning ring 34. In this way, when the stud bolts 43 are tightened, the threads at the lower ends can drive the multiple extrusion plates 41 to move closer to the outer wall of the ignition burner body 2 inside the positioning ring 34. The first nut 44 is sleeved on the outer side of the threads below the multiple stud bolts 43, and the second nut 45 is sleeved on the outer side of the threads above the multiple stud bolts 443. By rotating the first nut 44 and the second nut 45 in opposite directions, the first nut 44 and the second nut 45 are respectively pressed against the outer side of the positioning block 33 and the inner side of the positioning ring 43, which can lock the position of the stud bolts 43, so that both sides of the stud bolts 43 are restricted and not easy to loosen. The embedded part cooperates with the outer side to tighten the installation structure of the ignition burner body 2, so that the ignition burner body 2 can be installed wherever the embedded part is installed. Compared with the suspended installation method, the installation position is wider and less restricted.

[0034] Example 2:

[0035] See also Figure 1-5: In this embodiment, an ignition and combustion-supporting device for a waste incinerator also includes an auxiliary support and reinforcement structure 5 including an extension plate 51 and an upper bracket 54. The upper bracket 54 is movably connected to the bottom end of the outer wall of the ignition burner body 2. A pad 53 is fixedly connected to the bottom of the upper bracket 54. The pad 53 is made of a high-carbon steel metal block that is resistant to pressure and heat. The pad 53 is set at the end of the extension plate 51. The pad 53 cooperates with the upper bracket 54 to lift the lower end of the ignition burner body 2 and apply an upward lifting force. The installation of the sample ignition burner body 2 is more secure, and the force on the embedded parts is more balanced. The extension plate 51 is fixedly connected to the middle side wall of the positioning ring 34, and the other end of the extension plate 51 is fixedly connected to the pad 53. The lower end of the extension plate 51 is fixedly connected to the oblique frame 52, which is made of high-strength heat-resistant aluminum alloy. The oblique frame 52 and the extension plate 51 form a triangular support structure, which can effectively improve the support and reinforcement effect. The other end of the oblique frame 52 is fixedly connected to the lower end side wall of the positioning ring 34.

[0036] Working principle:

[0037] The pad 53 is made of a high-carbon steel metal block that is pressure-resistant and heat-resistant. The pad 53 is arranged at the end of the extension plate 51. The pad 53 cooperates with the upper bracket 54 to lift the lower end of the ignition burner body 2 and apply an upward lifting force. In this way, the installation of the ignition burner body 2 is more secure and the force on the embedded parts is more balanced. The oblique frame 52 is made of high-strength and heat-resistant aluminum alloy. The oblique frame 52 and the extension plate 51 form a triangular support structure, which can effectively improve the support and reinforcement effect.
