Description

Technical Field

[0001] The invention belongs to the technical field of venting torch ever-burning lamps, and in particular relates to an venting torch electronic flame ever-burning lamp. Background Art

[0002] As a key facility for treating waste gas in the industrial field, the flare stack plays a vital role, especially in oil fields and chemical plants. Its core function is to convert harmful substances in the waste gas into carbon dioxide and water vapor with relatively small impact on the environment through the combustion process.

[0003] During this process, the gas pilot lamp plays the role of an ignition device, using gas as fuel to form a stable flame at the top of the torch, ensuring the continuity and stability of the torch combustion.

[0004] Faced with the global call for controlling the peak of carbon emissions and reducing carbon emissions, many petrochemical companies have begun to take effective measures to reduce emissions. In the use of venting torches, this is usually reflected in turning off the long-burning lamps that continuously consume gas and switching to a more environmentally friendly automatic ignition system. The system uses venting detection components such as flow switches, pressure switches, flow meters and pressure transmitters to monitor gas emissions in the venting pipeline in real time. Once emissions are detected, the system will automatically ignite and ignite the flare gas, realizing the so-called "venting first and then igniting" ignition method.

[0005] Although the automatic ignition system has obvious advantages in saving gas, the performance of this system depends largely on the sensitivity and reliability of the venting detection element. For example, under low flow rate conditions, the flow switch may malfunction; and in the detection of gas pressure in the pipeline, the pressure switch and pressure transmitter may not be completely accurate. In addition, in the case of large pipe diameter and low flow, the measurement accuracy of the flow meter may be affected, resulting in failure to trigger ignition in time, causing the leakage of combustible gas to pollute the environment. The instability of the venting air may also interfere with the reading of the flow meter. At the same time, the high cost of large-caliber flow meters is also an issue that cannot be ignored. It is neither economical nor practical. Frequent ignition operations may also increase the failure rate of the ignition device, reduce the success rate of ignition, and in some cases may cause combustible gas to leak from the venting torch, posing a safety hazard. Summary of the invention

[0006] In order to solve the problem in the above-mentioned prior art that when using traditional gas-fired ever-burning lamps, the long-term operation of the ever-burning lamps leads to excessive fuel gas consumption and high carbon emissions, and when using automatic ignition gas lamps, the failure rate increases and the ignition success rate decreases due to repeated and frequent ignition of the ignition device, which further leads to the leakage of combustible gas, the present invention proposes a venting torch electronic flame ever-burning lamp, which can generate an electronic flame to ignite the combustible gas discharged by the venting torch, does not need to consume fuel to maintain the flame, is more environmentally friendly and simple to maintain, is not prone to failure, and avoids the leakage of combustible gas.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: an electronic flame ever-burning lamp for a venting torch, comprising a ever-burning lamp body, an exhaust restraint device, a cable, a PLC control box and a high-voltage generator, wherein the ever-burning lamp body comprises an ignition electrode and a mounting bracket, wherein the ignition electrode is mounted on the mounting bracket, and the end of the ignition electrode is an ignition nozzle; the cable comprises a power supply cable and a high-voltage cable, wherein the power supply cable is connected to the power grid and the PLC control box, wherein the power supply cable supplies 220V industrial frequency AC power to the PLC control box, and the PLC control box transmits the power to the PLC control box. To the high-voltage generator, the high-voltage generator converts the alternating current into high-frequency pulse direct current, and the high-voltage generator transmits the high-frequency pulse direct current to the ignition electrode through the high-voltage cable; the high-voltage generator converts the AC220V industrial frequency alternating current into high-frequency pulse direct current, and then transmits it to the ignition electrode installed on the top of the venting torch through the high-voltage cable, so that the ignition nozzle of the ignition electrode continuously sprays out an electronic flame with a temperature exceeding 1200°C and an arc length exceeding 120mm, and when combustible gas passes through the ignition nozzle, it can be directly ignited by the electronic flame;

The RTU is usually installed at a remote location and is used to collect and process field data). The armored thermocouple is arranged on the top of the ignition electrode, and the armored thermocouple is connected to the RTU. The RTU is connected to the PLC control box through the control cable. The armored thermocouple is used to detect the temperature of the ignition electrode and feed it back to the PLC control box.
