Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction equipment technology, specifically to a novel ignition gun and ignition device. Background Technology

[0002] During oil drilling, when drilling reaches a high-pressure oil and gas layer, if the drilling fluid column pressure is lower than the layer pressure, the high-pressure oil and gas flow will invade the wellbore and gradually rise towards the wellhead, potentially causing a blowout or well kick. In this situation, drilling workers will shut off the blowout preventer and take appropriate measures such as throttling and venting. The vented natural gas needs to be ignited; otherwise, if it mixes with air in a certain proportion, it poses a risk of explosion. Furthermore, the vented gas contains harmful gases such as H2S, which can endanger human lives.

[0003] Existing ignition guns are typically simple, have a low ignition success rate, and lack adjustment functions, making it difficult to control the direction of the flame during ignition. This is especially problematic in harsh ignition environments and when installation locations are limited. Utility Model Content

[0004] The present invention aims to solve the problem that the flame jet direction of the ignition gun is not easy to control during ignition, resulting in a low ignition success rate.

[0005] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows:

[0006] A novel ignition gun includes a burner head and an injector installed inside a casing. A conductive rod is installed above the casing, and the ignition head, connected to the conductive rod, extends into the casing and is positioned above or in front of the nozzle of the injector. The burner head has a bent structure and is fixed to the casing via a rotating flange. The direction of the flame jet during ignition can be changed by adjusting the installation position of the rotating flange, thereby ensuring a high ignition success rate.

[0007] Furthermore, the ignition head and the conductive rod are connected by an elbow.

[0008] Furthermore, the injector adjusts the damper distance via an adjusting rod, and the damper distance is not less than 6mm.

[0009] Furthermore, the ignition gun is provided with a heat insulation box on the outside, and a lifting ring is provided on the outside of the heat insulation box.

[0010] Furthermore, a support base is provided on the outside of the casing.

[0011] An ignition device includes an ignition gun as described above, a control skid, and an ignition gas reservoir. The ignition gas reservoir is connected to the injector of the ignition gun via a gas pipe. The control skid is connected to the conductive rod of the ignition gun via an ignition cable. The control skid is equipped with a power source or has an external power supply. Preferably, the gas pipe is an armored liquefied petroleum gas (LPG) hose.

[0012] Furthermore, the control skid includes a skid body, a solar panel on the top of the skid body, and a battery inside the skid body that is connected to the solar panel. The battery supplies power to the electrical components and ignition gun mounted on the skid body.

[0013] Furthermore, the ignition device also includes a remote control box. The skid is equipped with an electrical control box, a solar power supply system, and a valve group. The remote control box is connected to the actuator on the control skid.

[0014] Furthermore, it also includes an oil tank, and an oil drip basin is provided below the side of the burner head of the ignition gun, which is connected to the oil tank through an oil pipe.

[0015] Furthermore, the fuel tank is equipped with a filler port, a drain port, and a drip port. A level gauge is installed on the fuel tank, and an oil receiving tray is located below the fuel tank. A transport skid is located below the oil receiving tray.

[0016] The beneficial effects of this utility model are:

[0017] I. This utility model proposes a novel ignition gun. The ignition gun adopts a bent combustion head, and the combustion head is fixed to the protective sleeve by a rotating flange. This allows the entire ignition gun to be stably fixed in a suitable position (on the discharge pipeline). By adjusting the installation position of the rotating flange, the direction of the flame jet during ignition can be changed. The operator can determine the orientation of the combustion head according to the specific conditions of the ignition site, which is conducive to successful ignition. This novel ignition gun has a wider range of applicable environments.

[0018] II. In this utility model, the ignition head and the conductive rod are connected by an elbow, wherein the elbow structure is preferably made of a high-temperature resistant material, and the elbow structure facilitates the ignition head to turn and extend into the inside of the protective tube.

[0019] Third, in this utility model, the injector adjusts the damper distance via an adjusting rod. The damper distance is not less than 6mm to ensure air intake and facilitate successful ignition.

[0020] Fourth, in this utility model, a heat insulation box is provided on the outside of the ignition gun. The heat insulation box reduces the heat radiation received by the ignition gun to a certain extent. A lifting ring is provided on the outside of the heat insulation box. The lifting ring facilitates the transfer of the ignition gun by the lifting tool during transportation and installation.

[0021] V. In this utility model, a support base is provided on the outside of the protective sleeve, and the main components of the ignition gun are fixed inside the protective sleeve. The design of the support base facilitates the installation and fixing of the ignition gun.

[0022] VI. This utility model also proposes an ignition device with a preferred structure, including an ignition gun, a control skid, and an ignition gas source storage tank. The ignition gas source storage tank stores flammable gases such as liquefied petroleum gas (LPG) or propane. During use, LPG or propane is used as the ignition gas source to burn off the released gas. The ignition gas source storage tank is connected to the injector of the ignition gun via a gas pipe. The control skid is connected to the conductive rod of the ignition gun via an ignition cable. The control skid is equipped with a power supply or has an external power supply. Preferably, the gas pipe is an armored LPG hose. The ignition gun is the type of ignition gun described in this utility model that can change the direction of the flame during ignition to ensure a high success rate. More preferably, the power supply in this ignition device uses a solar power system including solar panels and batteries as the main power source, making the ignition device more widely applicable, especially in work locations lacking power.

[0023] VII. This utility model also includes an oil tank. An oil drip basin is located below and to the side of the ignition gun's burner head, connected to the oil tank via an oil pipe. When there are excessive impurities in the released gas, especially in harsh working conditions or weather, or when the ignition gas source tank is depleted, oil can be supplied to the drip basin from the oil tank to ignite the fuel and achieve continuous flame ignition. Preferably, the oil tank in the ignition device is equipped with a filler port, a drain port, and an oil drip port. A level gauge is installed on the oil tank to monitor the fuel level, prompting workers to replenish fuel promptly. An oil receiving tray is located below the oil tank to collect overflowing fuel during use, preventing fuel or fuel-containing waste from dripping / falling directly onto the ground, polluting the environment, and posing certain safety hazards.
