In oil drilling, natural gas extraction, and chemical production processes, it is often necessary to burn off vented gases to prevent direct pollution. The following problems are frequently encountered when handling vented gases:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] like Figure 1-7As shown, embodiments of this utility model provide an adaptive wide-range adjustable low-emission internal combustion venting ignition device and control strategy:

[0043] The entire equipment adopts a closed combustion design, using naturally circulated air as the combustion / cooling medium. Combustion is completed inside the ground flare incineration tower, achieving no open flame or black smoke on the outside during combustion.

The bottom of the cylinder 1 is fixed to the movable base 12. The main burner 2, which enables multi-stage combustion, is installed inside the cylinder 1.

A windbreak 8 is installed on the lower outer side of the cylinder 1. The intelligent control system 17 is installed outside the windbreak 8.

[0045] As a preferred technical solution: the cylindrical body 1 and the movable base 12 of the ground flare incineration tower are designed as separate units; the movable base 12 is composed of multiple equally divided units, the middle part of which is a circular structure for supporting the cylindrical body 1; see appendix. Figure 4 Each equal-divided unit includes a base plate 12-2, a connecting plate 12-3, and a lifting ring 12-1. The base plates 12-2 are spliced ​​together, and the connecting plates 12-3 on the sides of the base plates 12-2 are connected by bolts or other connectors. The lifting rings 12-1 are located at the four corners of the base plates. In this embodiment, there are three base plates 12-2, each with an obtuse 120° angle on its inner side. The three base plates 12-2 are spliced ​​together, forming a circular structure at their center. The connecting plate 12-3 includes a plate at the center and plates at the edges. After two base plates are joined, the two sides of the connecting plate are fixed to the two base plates by quick-connect bolts, achieving base plate connection. This allows for quick installation, convenient relocation, and shared use across different work locations, saving on equipment procurement investment. For larger bases, a splicing design can be adopted to achieve flexible movement and relocation. The lifting rings 12-1 are used to lift the base plates.

[0046] Preferably, the inner wall of the cylinder 1 is provided with a refractory layer of lightweight refractory material. The refractory layer is made of ceramic fiber modules spliced ​​together and fixed to the cylinder wall by high-temperature resistant stainless steel claw studs; the surface of the refractory layer is sprayed with a refractory-reinforced coating. In this embodiment, the internal combustion venting ignition device adopts a closed combustion design, using naturally circulated air as the combustion / cooling medium. Combustion is completed inside the ground flare incineration tower cylinder, achieving combustion without external open flames or black smoke. The cylinder 1 is a vertical structure, made of rolled steel plate, with externally rolled reinforcing hoops to improve cylinder strength. Multiple lifting lugs are designed on the cylinder 1 for convenient horizontal and vertical hoisting.

[0047] In another preferred embodiment, the main burner 2 adopts a double-layer low-NOx burner head structure; low-NOx ejector nozzles 19 are installed on the nozzles of both the inner burner head 1-2 and the outer burner head 1-1. The inner burner head 1-2 has three concentrically arranged rings of nozzles; the outer burner head 1-1 has two concentrically arranged rings of nozzles. The inner and outer burner heads can be flexibly adjusted and controlled according to the required combustion air release volume, allowing the inner or outer rings to burn independently, or the inner and outer rings to burn together, achieving adaptive wide-range adjustment.

[0048] Preferably, the nozzle of the burner head is equipped with a low-NOx ejector nozzle 19, which can entrain surrounding natural air and flue gas produced after combustion, mix them evenly, and disperse and uniformly distribute the airflow. This can reduce the temperature of the combustion flame, effectively suppress the generation of CO and NOx, and achieve the purpose of low-NOx and low-carbon combustion emissions to meet increasingly stringent environmental protection requirements.

[0049] In a preferred embodiment, the ignition and flame detector 3 includes an igniter 3-1 and a flame detector 3-2. The igniter 3-1 comprises 2-4 small, individually controlled ignition burners that burn continuously throughout the entire operation, providing a stable flame for the ground flare. The flame detector 3-2 is a flame monitor. In this embodiment, the igniter 3-1 uses an ejector-type atmospheric burner with automatic electrode discharge ignition. The ignition burners are arranged at multiple locations, allowing for continuous combustion during operation, providing a stable flame for the ground flare, and also providing wind and rain protection.

[0050] The emission monitoring system 16 includes an outlet pipe, a gas analyzer, and a data acquisition module. The outlet pipe is located on the upper side of the cylinder; the gas analyzer and the data acquisition module are both housed within the intelligent control system.

[0051] The main gas flow process 5 is the main gas delivery process during the combustion of the main burner, including a gas pretreatment device, a main gas electric gate valve, a main pressure detection device, and an inner / outer layer flame gas electric control valve. The gas pretreatment device includes filters and flame arresters installed on the main gas delivery pipeline; the main pressure detection device includes pressure gauges and pressure transmitters installed on the main gas delivery pipeline; an emergency venting process 7 is also provided on the main gas flow process 5, equipped with an emergency venting electric valve. A multi-position igniter 3-1 is installed on the cylinder 1, connected to the ignition gas flow process 6. The ignition gas flow process 6 is the branch gas delivery process for the igniter, including a manual ball valve, a pressure regulating valve, an ignition solenoid valve, and a branch pressure detection device installed on the branch gas delivery pipeline; the branch pressure detection device includes pressure gauges and pressure transmitters installed on the branch gas delivery pipeline; a flame detector, i.e., a flame detector 3-2, is also installed next to the igniter.

[0052] The cylinder body is equipped with a temperature-measuring thermocouple 4, an emission monitoring system 16, and also includes components such as an air barrier 8, a ladder 9, an electric damper 10, a maintenance manhole 11, a bracket 13, a lifting ring 14, and a rain cap 15. Furthermore, the air barrier 8 and ladder 9 on the cylinder body 1 adopt a hook-and-loop structure, secured with a central screw for easy assembly and disassembly; a viewing hole is provided near the ignition burner, which can be used as a manual ignition channel, enabling manual ignition in case of ignition system failure; a rain cover is provided on the mounting hole of the temperature-measuring thermocouple 4; a rain cap 15 is provided on the top of the cylinder body 1; and a fall-prevention safety ring is provided at the top of the ladder 9 to improve safety when removing the hook during installation.

[0053] As a preferred technical solution: An intelligent operation control box 17 and a high-voltage igniter electrical control cabinet 18 are configured on-site. The intelligent operation control box 17 is located outside the windbreak 8. It incorporates a PLC programmable controller, a touchscreen, and low-voltage electrical components for ignition control and flame detection. The intelligent operation control box 17 is a fully enclosed, rainproof type. It also features wireless remote control, enabling remote operation of equipment ignition and shutdown within a 200m radius in open areas or a 100m radius in general locations. The intelligent control system is interlocked with electrical components such as the main gas flow 5, ignition gas flow 6, emergency venting flow 7, temperature measuring thermocouple 4, inner and outer flame gas electric control valves, and emission monitoring system.

[0054] As a preferred technical solution, the intelligent control system has two selectable functions: one is a combination of manual and automatic control, and the other is a fully automatic program control mode. Regardless of the control mode, it can achieve one-button start of the ignition program and has functions such as flame monitoring and temperature alarm.

[0055] An emission monitoring system 16 is installed on-site for the internal combustion venting ignition device, including an outlet pipe, a gas analyzer, and a data acquisition module. The outlet pipe is located on the upper side of the cylinder and is used for gas collection during gas analysis. Both the gas analyzer and the data acquisition module are housed within the intelligent control system and can display data on a touchscreen and an industrial computer. The gas analyzer can monitor the composition of the gases after combustion in real time, including the concentrations of pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM). The data acquisition module transmits the monitored data to the control system, providing a basis for combustion adjustment.

[0056] As a preferred option, the intelligent control system adopts centralized control using an industrial computer, an S7-200smart, and a touch screen. Based on data from the emission monitoring system and parameters such as temperature and pressure inside the cylinder, the control system adjusts the operating parameters of the ignition system and the combustion regulation system in real time. It adjusts the gas valve opening through PID control, adjusts the air valve opening according to the air-fuel ratio, and corrects the air-fuel ratio value based on monitoring data to achieve adaptive wide-range adjustment and low-emission combustion control.

[0057] To further explain, the combustion regulation system includes an electric regulating device for the size of the gas flame (i.e., the inner flame gas control valve 5-1 and the outer flame gas control valve 5-2) and an electric regulating device for the air (i.e., the electric damper 10).

[0058] Furthermore, igniter 3-1 employs electrode ignition, using oilfield vent gas as the ignition gas. Interfaces for other high-calorific-value gases are also reserved. During the operation of the flare wall, it will continuously burn, serving as a pilot flame to provide a reliable and stable ignition source for the flare.

[0059] Furthermore, the ignition gas source is drawn from the vent supply pipeline, passing through a manual ball valve, pressure regulator, and solenoid valve before entering the ignition burner. The PLC control system determines the ignition signal, and the ignition process is initiated through various methods, including operating the touchscreen buttons or pressing the remote control ignition button. This automatically executes ignition electrode discharge, valve opening, and flame detection. Additionally, a purge fan and CH4 concentration detection can be added as optional purging features.

[0060] Furthermore, the control strategy of this utility model includes the following steps:

[0061] (1) Initial ignition stage

[0062] When the vented gas enters the combustion equipment inside the cylinder, the ignition controller automatically selects the appropriate ignition electrode for ignition based on the gas composition and flow rate. The ignition time and ignition intensity are dynamically adjusted according to the temperature and pressure inside the combustion chamber to ensure rapid and stable ignition of the vented gas.

[0063] (2) Ignition of the main burner stage

[0064] The PLC collects the flame signal captured by the flame detector. Once the ignition flame signal is stable, the PLC outputs a signal to open the main gas electric butterfly valve or manually open it.

[0065] (3) Adaptive wide-range regulation and monitoring stage of combustion process

[0066] After the main burner is ignited, the PLC control system automatically adjusts the combustion parameters in the combustion chamber based on changes in the flow rate, composition, and pressure signals of the vented gas.

[0067] When the venting gas flow rate is small, the inner flame gas control valve is opened first, and the air intake volume is automatically matched according to the venting gas volume.

[0068] When the venting gas flow gradually increases to the point that the inner layer is not sufficient for combustion, the outer layer flame gas control valve is opened, the fuel injection device increases the fuel injection quantity, the air conditioning device increases the air intake quantity, and at the same time the ignition controller adjusts the ignition intensity to ensure a stable combustion environment in the combustion chamber.

[0069] When the composition of the vented gas changes, the intelligent control system adjusts the operating parameters of the ignition system and combustion regulation system in real time based on the data from the gas analyzer and parameters such as temperature and pressure inside the cylinder. It adjusts the gas valve opening through PID control, adjusts the air valve opening according to the air-fuel ratio, corrects the air-fuel ratio value based on monitoring data, optimizes the combustion process, adapts to vented gas with different compositions, and achieves adaptive wide-range regulation and low-emission combustion control.

[0070] During combustion, the emission monitoring system monitors the composition of the gases after combustion in real time, and the control system determines whether combustion is complete based on the monitoring data. If the concentration of pollutants such as CO and NOx exceeds the standard, the control system will adjust the operating parameters of the fuel injection device and the air conditioning device to optimize the combustion process, making combustion more complete and reducing pollutant emissions.

[0071] (4) Safety protection and control stage

[0072] The intelligent control system also has safety protection functions. If the flame signal feedback is interrupted during the adjustment process, or if the temperature or pressure inside the combustion tower exceeds the set safety value, an alarm will be issued and the emergency venting pipeline solenoid valve will be opened immediately and the main gas electric regulating valve will be automatically shut off after a delay to stop ignition and prevent the pressure or temperature in the combustion chamber from being too high, thus ensuring the safe operation of the device.

[0073] The four stages of control include semi-automatic control and fully automatic control;

[0074] (1) Semi-automatic control includes the main gas flow and ignition gas flow connected to the venting pipeline. Manual valve groups are installed in the main gas flow. The ignition detector is connected to the intelligent control system, and the intelligent control system is connected to the temperature measuring thermocouple.

[0075] When venting is required, oilfield gas is delivered as venting air through pipelines to the valve group interface of the flare incinerator. Under normal operating conditions, the oilfield gas is adjusted to a suitable pressure by the pressure regulator in the ignition gas flow. At this time, ignition can be performed on the touch screen or remote control of the intelligent control system. The intelligent control system automatically executes the ignition process. The ignition electrode of the igniter generates an electric spark, the ignition solenoid valve opens, and the ignition gun is ignited. The main gas electric gate valve is manually and slowly opened to gradually increase the main gas flow and ignite the main burner for venting. When the pressure regulator or solenoid valve in the ignition gas flow malfunctions, manual ignition is used. The ignition electrode discharges, the manual valve group in the main gas flow is manually opened, fuel enters the igniter burner, and after confirming the establishment of the ignition flame, the main gas gate valve is manually opened to ignite the main burner.

[0076] (2) Fully automatic control: Compared with semi-automatic control, the main gas flow process is equipped with an automatic venting valve group, a regulating valve group, a gas pressure detection device and an emergency venting electric valve.

[0077] The venting gas enters the main burner through a pipeline. The main burner and igniter are controlled by pressure transmitters in the main gas flow and ignition gas flow, respectively, as triggering conditions.

[0078] The intelligent control system automatically executes the ignition process. The ignition electrode of the igniter generates an electric spark, the ignition solenoid valve opens, and the ignition gun is ignited.

[0079] The combustion and pressure transmitter settings of the main burner are related to pressure. When the pipeline pressure reaches the system's set start-up pressure, after confirming the establishment of the ignition flame, the automatic valve group and regulating valve group of the main burner of the flare are activated to ignite the main burner. When the pressure is lower than the burner's shut-off pressure, the emergency venting electric valve opens to extinguish the burner. The intelligent control system is connected to the temperature measuring thermocouple 4 and the emission monitoring system 16, and can collect emission flow signals as the basis for adjustment.

[0080] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles, scope and spirit of the present invention, all of which fall within the scope of the present invention as claimed, defined by the appended claims and their equivalents.
