DETAILED DESCRIPTION

[0021] like Figures 1 to 4 As shown, a regenerative converter gas diffusion ignition device comprises a combustion head 1, a gas pipeline 6, a support plate 7 and a sliding rod 10.

[0022] The burner head 1 is arranged above the gas pipeline 6, and the bottom end of the burner head 1 is fixedly arranged on the side wall of the gas pipeline 6 through a fixing clamp ring 101. An air inlet 5 is arranged on the side wall of the burner head 1.

[0023] An ignition chamber 2 is disposed in the combustion head 1 , and a first telescopic ignition tube 3 and a second telescopic ignition tube 4 are provided on the right end surface of the ignition chamber 2 , and the first telescopic ignition tube 3 and the second telescopic ignition tube 4 have different heights.

[0024] A support plate 7 is fixedly arranged on the outer wall of the gas pipeline 6, a sliding rod 10 is slidably arranged on the upper surface of the support plate 7, a lifting frame 11 is arranged on the upper end of the sliding rod 10 through a top screw 1101, and an insulating column 12 is arranged on the left end surface of the lifting frame 11. A high-voltage generator 13 cooperating with the insulating column 12 is fixedly arranged on the lower surface of the lifting frame 11.

[0025] When the insulating column 12 cooperates with the first telescopic ignition tube 3, the second telescopic ignition tube 4 is blocked by a plug; when the insulating column 12 cooperates with the second telescopic ignition tube 4, the first telescopic ignition tube 3 is blocked by a plug.

[0026] Specifically, the lower surface of the sliding rod 10 cooperates with the sliding groove 701 on the supporting plate 7 , and a driving block 1001 is fixedly provided on the sliding rod 10 .

[0027] The support plate 7 is fixedly provided with a vertical plate 8 , and the vertical plate 8 is provided with a lead screw 901 threadably matched with the driving block 1001 , and the lead screw 901 is driven by a motor 9 .

[0028] The use process of the utility model is as follows:

[0029] First, open the gas valve, and the gas is discharged into the combustion head 1 through the gas pipe 6. At this time, air is mixed into the air inlet 5 on the combustion head 1. At this time, the air and gas are mixed and enter the ignition chamber 2. Then, the lead screw 901 and the drive block 1001 are controlled to push the sliding rod 10 to drive the insulating column 12 to insert into the first telescopic ignition tube 3 or the second telescopic ignition tube 4 until the high-temperature resistant and high-voltage wire on the insulating column 12 is inserted into the ignition chamber 2. Then, the high-voltage generator 13 is controlled to generate high voltage electricity, which is transmitted to the ignition chamber 2 through the high-temperature resistant and high-voltage wire. At this time, the high-temperature resistant and high-voltage wire generates a high-voltage arc in the ignition chamber 2, thereby igniting the gas after the mixture of gas and air, and spraying a flame from the upper part of the ignition chamber 2 to ignite the released gas for combustion. Finally, the lead screw 901 and the drive block 1001 drive the high-temperature resistant and high-voltage wire on the insulating column 12 to exit the ignition tube to avoid damage caused by long-term high-temperature combustion. The above is the use process of the entire heat storage converter gas release ignition device.
