[0024] Referring to Figs. 1-2 As shown in the figure, the utility model discloses a novel high-strength high-stability sky ladder type ion igniter, including power supply 1, the output of power supply 1 is connected to circuit assembly, the circuit assembly includes first transformer 2 and circuit board 3, the output of circuit assembly is connected to second transformer 11, including body 4, the electrode assembly is arranged in body 4, second transformer 11 is connected to electrode assembly through high-voltage cable 13, the electrode assembly includes electrode positive pole 5 and electrode negative pole 6, electrode positive pole 5 is arranged at the central position of body 4, the top of body 4 is conical structure 7, the periphery of conical structure is uniformly distributed with electrode negative pole at the position of electrode positive pole.
[0025] Circuit assembly includes cooling fan 8 and fin 12, the input parameter of power supply 1 is 220V, 50HZ, is converted into 24V direct current after first transformer 2, is converted into 11kV high-frequency high-voltage by second transformer 11. Because the design of the igniter is used in high-altitude torch, it is different from the igniter used on the ground, and the problem of high-altitude transportation cannot be avoided. Considering the convenience of maintenance, the power supply 1, the circuit assembly, two transformers and other parts of the device must be installed on the ground, and the electrode assembly is installed in the high altitude, and only high-voltage cable 13 can be used to connect them.
[0026] One side of first transformer 2 is provided with cooling fan 8, and the input end of power supply 1 inputs 220V, 50HZ. A pollution discharge groove 9 is arranged on the body 4 close to the bottom of the conical structure 7, and the electrode assembly is made of 310S and 304 stainless steel materials to ensure its strength in high-temperature environment.
[0027] The diameter of the top of the conical structure 7 is greater than that of the bottom, the diameter of the bottom of the conical structure 7 is 25-57mm, and the maximum diameter of the top of the conical structure 7 is 159mm, and the minimum can be 32mm, but the diameter of the top is definitely greater than that of the bottom.
[0028] The performance is as follows:
[0029] 1. Covering characteristics: the arc covering area is large, and the flame is in the shape of a candle, rather than a filament or a spark. The minimum arc length is 8 mm (i.e. the minimum electrode gap), and the maximum arc length is 20 mm (i.e. the maximum electrode gap). The flame covering area is 20 mm-480 mm in the axial direction; due to the electrode gap and the electrode lengthening, the arc covering area is larger, which is good for preventing carbon deposition in media containing dust and heavy components (C5 and above). It can also be used for companion burning.
[0030] 2. High temperature characteristics: the arc temperature is high, which is tested to be >1200℃. The paper is ignited in 1s, the cigarette is ignited in 2s, the wood is ignited in 3s, the iron wire (0.6mm in diameter) is melted in 5s, and the steel plate (2mm) is red in 10s; it is beneficial to the ignition of low calorific value media.
[0031] 3. Wind resistance characteristics: the arc has strong wind resistance, and the flame will waver in the electrode axial direction when blown by an electric hair dryer (wind speed 18m / s), but it will not be extinguished;
[0032] 4. Water resistance characteristics: the arc has strong water resistance, and will not be extinguished when sprayed by a watering can;
[0033] 5. Low temperature characteristics: the arc has low temperature resistance, and the electrode arc gap will be reduced (by at least 5mm) in a -5℃ environment, but the arc will not be affected. As the electrode heats up and the temperature rises, the electrode arc gap will gradually increase to normal.
[0034] 6. Arc characteristics: the arc can be continuously drawn, and can be continuously drawn for 3.5h in destructive use, without the need to stop power or store energy during the period when the circuit and electrical components are intact. The continuous arc mode can be set to 5min when igniting. It can also be used for companion burning.
[0035] 7. Arc characteristics: the arc characteristics are not affected by air density, and can be drawn in a vacuum, which means that thin air will not affect the temperature; it is more targeted for high-altitude projects.
[0036] 8. The design of the ignition rod is suitable for all media discharged by torches in the fields of petroleum, chemical industry, metallurgy, etc.
[0037] 9. Lifetime design: according to the continuous arc of 3min / each, 10 times / day, and the total number of days is 15 months. Therefore, the reliability test is continuous arc for 3h, and the lifetime test is continuous arc for 3min, stop for 1min, continuous arc for 3min, stop for 1min, and so on, for 10 consecutive days.
[0038] 11. Insulation design: In order to prevent running electricity, leakage, breakdown and short circuit, under the premise of "resisting high voltage 10kV and high temperature 800℃", the tensile tube of more than 99% alumina ceramic is adopted and the size is customized, and the concentricity of the ceramic tube is ensured, the wall thickness is uniform, and there is no porosity, shrinkage, crack. In fact, 99% ceramic corundum ceramic tube with a wall thickness of 2.5 is used to ensure that the ceramic tube does not run electricity, does not leak electricity, does not break down, and does not short circuit.
[0039] 12. Cost control: A set of torch device installs the igniter 2-4 sets. And 2-4 sets of igniter may be ignited at the same time, or may be ignited separately. In order to save cost, the common negative electrode can be used, that is, n positive electrodes + 1 common negative electrode.
[0040] 13. Since the electrode is installed in the high altitude and cannot be visually observed, a high voltage output indicator lamp is installed on the second transformer 11 to facilitate the judgment of whether the high altitude electrode is arcing, and to facilitate the on-site installation and debugging.
[0041] The characteristics of the electrode assembly are as follows:
[0042] Through test: The electrode arcing gap is 18-63mm, the axial (longitudinal) is 160mm, which means that a "wavy push, endless" fan-shaped flame with a minimum opening of 18mm, a maximum opening of 63mm, and a longitudinal (axial) of 160mm (designed according to actual situation) can be formed between the electrodes, and the arc strength is large, the temperature is high, and the duration is durable.
[0043] In order to prevent the electrode from softening and deforming due to the influence of high temperature environment, affecting the arcing, the positive electrode is thickened, and the negative electrode is a three-dimensional (cone) structure, which ensures that it does not deform, dislocate and misplace in high temperature environment.
[0044] In order to expand the ignition surface, the positive electrode is set as the center, and the electrode rigidity is increased to avoid deformation and misplacement of the electrode due to high temperature environment. Therefore, the center electrode is set as the positive electrode, the circumference is the negative electrode, and small holes are opened on the circumference of the upper part of the cone. Since the fuel gas comes from the small head of the cone, the fuel gas in the 360° direction meets the cone and collides, part of the fuel gas enters the inside of the cone through the small hole and ignites with the arc between the electrodes. At the same time, it can also avoid the water and dust mixed in the fuel, which is beneficial to protect the electrode and reduce the accumulation of dust to affect the conduction.
[0045] As can be seen from the above, the igniter is a three-dimensional ignition mode product, the mode is: axial: wave propulsion, endless; radial: 360° all-around; working condition: suitable for strong wind, heavy rain, heavy snow, lack of oxygen and low temperature (0- -40℃).
[0046] The above-described embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitutions or transformations made by the skilled in the art based on the present application are within the protection scope of the present application. The protection scope of the present application is subject to the claims.
