The nozzle assembly 200 is arranged in the fire shield 100, and the ignition electrode 300 is arranged corresponding to the nozzle assembly 200 for igniting the nozzle assembly 200.

[0045] Among them, the fire protection cover 100 includes an access end cover 110, the nozzle assembly 200 includes a plurality of nozzle groups at different distances from the access end cover 110, each nozzle group is at least corresponding to an ignition electrode 300, each nozzle group includes a plurality of nozzles, the ignition electrode 300 is introduced by the access end cover 110 and is arranged corresponding to at least one nozzle of each nozzle group, and the ignition electrode ignites all the nozzles of the nozzle group.

[0047] like Figure 2 As shown, the multiple nozzles of each nozzle group of the nozzle assembly 200 of the linear burner ignition structure of the present invention are distributed in a ring shape.

[0048] In detail, in one embodiment of the linear burner ignition structure of the utility model, there are two nozzle groups, such as Figure 1 and Figure 2 As shown, there are a first nozzle group 210 and a second nozzle group 220, respectively. The first nozzle group 210 includes a plurality of first nozzles 211, and the second nozzle group 220 includes a plurality of second nozzles 221.

[0049] The ignition electrode 300 includes a first ignition electrode 310 disposed corresponding to the first nozzle group 210 and a second ignition electrode 320 disposed corresponding to the second nozzle group 220. The first ignition electrode 310 is disposed corresponding to at least one first nozzle 211 of the first nozzle group 210, and the first ignition electrode 310 is used to ignite each first nozzle 211 of the first nozzle group 210. The second ignition electrode 320 is disposed corresponding to at least one second nozzle 221 of the second nozzle group 220, and the second ignition electrode 320 is used to ignite each second nozzle 221 of the second nozzle group 220.

[0050] In one embodiment of the present invention, Figure 1 As shown, the first nozzle group 210 includes five first nozzles 211, and the first ignition electrode 310 is one and is set corresponding to the first nozzle 211A. The second nozzle group 220 includes six second nozzles 221, and the second ignition electrode 320 is one and is set corresponding to the second nozzle 221A. The nozzle assembly 200 is arranged in multiple layers with different heights (lengths). By setting corresponding ignition electrodes for each layer of the nozzle group, the one-time ignition success rate of the equipment is improved, and the risk of exceeding the standard of the non-methane total hydrocarbon value of the drying room exhaust is reduced.

[0051] In one embodiment of the present invention, Figure 2 As shown, the first nozzle group 210 includes six first nozzles 211, which are arranged in a ring.

The first nozzle group 210 is concentrically arranged with the second nozzle group 220, or in other words, the second nozzle group 220 is arranged around the first nozzle group 210.

[0052] In another embodiment of the linear burner ignition structure of the utility model, there are three nozzle groups. Figure 3 As shown, the difference from the previous embodiment is that, in addition to the first nozzle group 210 and the second nozzle group 220, this embodiment also has a third nozzle group 230. Preferably, the third nozzle group 230 is arranged concentrically with the first nozzle group 210 and the second nozzle group 220. Figure 1 The third nozzle group 230 includes a plurality of third nozzles 231, and the third nozzle 231 has a third distance from the access end cover 110, and the third distance is not equal to the first distance S1 or the second distance S2. For example, the third distance is less than the first distance S1, or the third distance is greater than the second distance S2, or the third distance is greater than the first distance S1 and less than the second distance S2, all of which are within the protection scope of the present utility model.

[0053] The ignition electrode 300 includes a third ignition electrode 330 disposed corresponding to the third nozzle group 230 . The third ignition electrode 330 is disposed corresponding to at least one third nozzle 231A of the third nozzle group 230 . The third ignition electrode 330 is used to ignite each third nozzle 231 of the third nozzle group 230 .

[0054] Each nozzle group may be provided with an ignition electrode. In some embodiments, each layer of nozzle groups may be provided with a plurality of ignition electrodes.

[0055] In one embodiment of the present invention, Figure 4 As shown, the first nozzle group 210 includes five first nozzles 211, and two first ignition electrodes 310 are respectively arranged corresponding to the first nozzles 211A and 211B. The second nozzle group 220 includes six second nozzles 221, and one second ignition electrode 320 is arranged corresponding to the second nozzle 221A.

[0056] In one embodiment of the present invention, Figure 5 As shown, the first nozzle group 210 includes five first nozzles 211, and one first ignition electrode 310 is provided corresponding to the first nozzle 211A. The second nozzle group 220 includes six second nozzles 221, and two second ignition electrodes 320 are provided corresponding to the second nozzles 221A and 221B respectively.

[0057] In one embodiment of the present invention, Figure 3 As shown, the first nozzle group 210 includes six first nozzles 211, and there is one first ignition electrode 310, which is arranged corresponding to the first nozzle 211A. The second nozzle group 220 includes six second nozzles 221, and there are two second ignition electrodes 320, which are arranged corresponding to the second nozzles 221A and 221B respectively. The third nozzle group 230 includes ten third nozzles 231, and there are two third ignition electrodes 330, which are arranged corresponding to the third nozzles 231A and 231B respectively.

[0058] When multiple ignition electrodes are set corresponding to each layer of nozzle groups, the two first ignition electrodes 310 corresponding to the first nozzle group 210 are staggered, the two second ignition electrodes 320 corresponding to the second nozzle group 220 are staggered, and the two second ignition electrodes 330 corresponding to the third nozzle group 230 are staggered, and their projections on the cross section of the nozzle group try to meet the angular distribution of 360° / n (n is the number of ignition electrodes). When all ignition electrodes on a single burner are ignited, they discharge simultaneously and ignite nearby nozzles at the same time, shortening the time required for complete ignition of all nozzles, reducing the risk of excessive non-methane total hydrocarbon value caused by failure of natural gas to burn at the moment of ignition, and improving the one-time ignition success rate of waste gas incineration equipment.

[0059] When implementing it, Figure 1 As shown, the ignition electrode 300 needs to be equipped with cooling compressed air 400 to prevent it from being burned by the high temperature flame. The specific number of ignition electrodes to be added needs to be determined according to the number of nozzle layers and whether there are redundant positions on the burner end cover.

[0060] The linear burner device of the present invention comprises an air supply assembly 500 and the above-mentioned linear burner ignition structure. The air supply assembly 500 is introduced into and connected to each nozzle group through the access end cover 110 of the linear burner ignition structure.

[0061] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
