Embodiment Construction

[0019] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0020] As shown in FIG. 1 , the ignition control method disclosed in the present invention is applied in the waste gas high-altitude flare ignition system in the petrochemical industry. The ignition control method mainly includes the automatic key steps of gas mixing, ignition, and flameout monitoring. The ignition includes igniting the internal pilot combustion head and igniting the eternal flame combustion head. As shown in Figure 2, the gas enters through the gas inlet 4 and passes into the inner ignition pipe and the permanent flame pipe respectively. The inner ignition control valve 2 and the pressure regulating valve 6 connected in series are arranged on the inner ignition pipe. Pilot control valve 2 and pressure regulating valve 6 are in parallel bypass control valve. First press the opening button of the automatic control system 11, the ex...

Abstract

The invention disclose an ignition control method, specially relates to an ignition control method for igniting another combustible gas by employing inner ignition mode, and is used for solving the weakness existing in current ignition method such as unsafe aloft ignition work, low ignition success rate, inconvenient maintain and so on. The method includes steps as following: mixing ignition gas with air, igniting inner ignition burning head, adjusting flame of the inner ignition burning head, igniting all-time fire burning head, shutting off the inner ignition system, automatically monitoring flameout and so on. For employing the inner ignition mode, the method can realize ground ignition, and ignition will not be affected by climate, environment, and the ignition success rate can be enhanced, and the method has better safety, is widely applicable for ignition control in petroleum chemical industry or other.

Description

technical field [0001] The invention relates to an ignition control method, in particular to an ignition control method for igniting another combustible gas by means of internal ignition. Background technique [0002] At present, waste gas (such as hydrogen sulfide, etc.) in the petrochemical industry is not easy to recycle, and most of them are vented and burned by high-altitude torches. The traditional ignition method is mostly to directly ignite the vented exhaust gas at high altitude, or to ignite the burning head of the eternal flame at high altitude. Both of these methods use high-altitude ignition as the main method. The high-altitude ignition head has been in a high-altitude, polluted, and high-temperature environment for a long time, and there are maintenance difficulties and potential safety hazards. The long-term pollution and high temperature of the ignition head will greatly reduce its service life. . In addition, there is also an external string fire ignition...
