[0023] Figure 3 This is a schematic diagram of the overall structure of the wind deflector. Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0027] Example 1

[0028] Reference Figure 2 This is the first embodiment of the present invention. This embodiment provides an installation structure that uses an electrode ignition unit for ignition. During ignition, the ignition needle extending into the combustion tube generates an electric arc after being energized, igniting the coke oven gas inside. This ignites the venting tower through the combustion tube, consuming the discharged gas and ensuring the safety and stability of the gas pipeline network. The ignition unit 1 includes a high-pressure porcelain insulator 11, an ignition electrode 12, and an ignition rod 14. The high-pressure porcelain insulator 11 is equipped with an ignition electrode 12, and the ignition electrode 12 is equipped with an ignition rod 14. The high-pressure porcelain insulator 11 electrically drives the ignition electrode 12, which in turn drives the internal ignition needle 142 to generate an electric arc, thereby igniting the internal gas. The high-voltage cable 13 located at one end of the ignition electrode 12 also better ensures the electric starting effect.

[0029] The main combustion tube 5 of the venting tower is provided with a second combustion tube 6 at one end and an ignition unit 1 on the second combustion tube 6. The other end of the main combustion tube 5 of the venting tower is provided with a first combustion tube 4. By providing combustion tubes on both sides of the main combustion tube 5 of the venting tower, the success rate of ignition can be guaranteed. At the same time, the two combustion tubes have different ignition methods, and dual-mode ignition can be achieved through different ignition methods.

[0030] When using the equipment, open the regulating valve 3 to open the coke oven gas pipeline 2, and start the ignition torch 8 and ignition unit 1. Ignite at the outlets of the first combustion pipe 4 and the second combustion pipe 6. After observing that the ignition is successful, open the main combustion pipe 5 of the venting tower and wait for the ignition to be successful to complete the ignition work.

[0031] Example 2

[0032] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an installation structure that solves the problem of shortened service life due to corrosion from sea winds. It includes a coke oven gas pipeline 2 installed on the first accompaniment pipe 4 and the second accompaniment pipe 6. A regulating valve 3 is installed on the coke oven gas pipeline 2. An installation bracket 61 is installed on the second accompaniment pipe 6. An outer sleeve 62 is installed inside the second accompaniment pipe 6. An inner tube 63 is installed inside the outer sleeve 62. Ignition is carried out by a double-layer pipeline. Coal gas is transported in the inner tube 63 and nitrogen is transported in the outer sleeve 62. Since nitrogen is an inert gas and is non-corrosive, it will not react with the coal gas and can also isolate the influence of the outside air on the inside. At the same time, nitrogen will not react with the internal ignition needle 142, thus ensuring its service life.

[0033] Preferably, the inner tube 63 is provided with a connecting partition 631, the inner tube 63 is provided with an ignition hole 632, the inner tube 63 is provided with a connecting pipe 64 connected to the coke oven gas pipeline 2, the outer side of the second accompaniment pipe 6 is provided with a connecting hole 65, the first accompaniment pipe 4 is provided with an ignition torch 8, the outer tube 62 is connected to the inner tube 63 through the connecting partition 631, and the center extension lines of the connecting hole 65 and the ignition hole 632 coincide with each other, so that the ignition needle 142 can be better installed and connected;

[0034] Furthermore, a wind deflector 7 is provided on the mounting bracket 61. Connecting ears 71 are provided at both ends of the wind deflector 7. A connecting groove 72 is provided at one end of the wind deflector 7. The wind deflector 7 has a semi-circular structure design. A protective groove is provided inside the wind deflector 7. The protective groove is filled with insulating material. The semi-circular structure of the wind deflector 7 can reduce the erosion of the ignition unit 1 by the external sea wind and better protect the ignition unit 1. The insulating material inside the wind deflector 7 can also reduce the damage to the wind deflector 7 caused by internal discharge.

[0035] During use, when the second combustion tube 6 is working, nitrogen is supplied through the outer tube 62. The nitrogen isolates the gas supplied through the connecting pipe 64 from the outside air, thereby reducing the leakage of internal gas. At the same time, the ignition rod 14 installed in the connection hole 65 on the outer tube 62 is protected by the insulating pad 141. During ignition, the supply of nitrogen is paused, and after ignition is completed, the supply of nitrogen in the outer tube 62 is resumed. The wind baffle 7 set on the outside of the ignition unit 1 can protect the ignition unit 1 from the corrosion of the outside sea wind and ensure the service life of the internal ignition unit 1.

[0036] Example 3

[0037] Reference Figures 1 to 3 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a solution to the problem of easy flameout and difficulty in ignition of the ignition device. It includes an ignition unit 1, which includes a high-pressure porcelain insulator 11, an ignition electrode 12, and an ignition rod 14. The high-pressure porcelain insulator 11 is provided with the ignition electrode 12, and the ignition rod 14 is provided with the ignition electrode 12. A high-voltage cable 13 is provided at the end of the ignition electrode 12 away from the ignition rod 14. An insulating pad 141 is provided on the ignition rod 14, and an ignition needle 142 is provided inside the insulating pad 141. The ignition needle 142 is protected by the frustum-shaped insulating pad 141, which can better reduce the damage to the outside caused by the electric arc when a discharge phenomenon occurs.

[0038] During use, when igniting, the regulating valve 3 is opened to open the coke oven gas pipeline 2, and the ignition torch 8 and ignition unit 1 are activated. Ignition occurs at the outlets of the first and second auxiliary combustion pipes 4 and 6. When the second auxiliary combustion pipe 6 is working, nitrogen is supplied through the outer casing 62. The nitrogen isolates the gas supplied through the connecting pipeline 64 from the outside air, thereby reducing the leakage of internal gas. At the same time, the ignition rod 14 installed in the connection hole 65 on the outer casing 62 is protected by the insulating gasket 141 by the internal ignition needle 1. 42. During the ignition process, the nitrogen supply is paused, the second combustion tube 6 is ignited, and the nitrogen supply in the outer tube 62 is resumed after ignition is completed. The wind baffle 7 located outside the ignition unit 1 can protect the ignition unit 1 from external sea wind corrosion and ensure the service life of the internal ignition unit 1. The ignition torch 8 used in the conventional ignition method will ignite the first combustion tube 4. After observing successful ignition, the main combustion tube 5 of the venting tower is opened and the ignition is completed.
