Description

Technical Field

[0001] This invention relates to the field of natural gas extraction equipment technology, and in particular to an energy-saving natural gas extraction flare regulating device. Background Art

[0002] On natural gas extraction platforms, flare heads are used to safely burn off excess combustible gases generated or released during production. Flare heads are typically located in the open, and their flame stability is highly susceptible to severe weather conditions such as strong winds and heavy rain. Strong winds can cause the flame to tilt, resulting in incomplete combustion and the production of large amounts of black smoke and harmful substances; rainwater can directly cause the flame to extinguish, resulting in unburned natural gas being released directly into the atmosphere, posing serious safety hazards (such as the risk of explosion), as well as causing energy waste and environmental pollution.

[0003] Currently, although some torch heads have been fitted with simple rain shelters or windbreaks, these are mostly fixed structures that cannot be adjusted according to weather conditions. In the absence of wind and rain, they may actually hinder flame combustion, affecting heat dissipation and combustion efficiency. Furthermore, their poor sealing makes them difficult to effectively resist the intrusion of slanting wind and rain.

[0004] Therefore, we propose an energy-saving natural gas extraction flare regulating device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving natural gas extraction flare regulating device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An energy-saving natural gas extraction flare adjustment device includes a fixed base and a movable cover. The movable cover is composed of at least two movable cover plates symmetrically hinged around a fixed ring. The cover plates open or close around the flare head axis. A connecting plate is fixed to the lower end of the hinge point of the cover plate. A screw cylinder is rotatably installed between the fixed base and the fixed ring. A screw ring is threaded onto the outer periphery of the screw cylinder. A support rod is hinged to each connecting plate corresponding to the screw ring. A motor and a worm gear are also installed on the fixed base. A worm wheel ring is meshed around the worm gear and is coaxially and fixedly connected to the screw cylinder.

[0008] In a further embodiment, the fixed base is installed below the torch head, the torch head passes through the fixed base, and the bottom of the fixed base is symmetrically provided with L-shaped support legs.

[0009] In a further embodiment, the movable cover is umbrella-shaped or an inverted petal shape formed by multiple cover plates.

[0010] In a further embodiment, the cover is composed of an inner and outer aluminum foil layer, a ceramic fiber felt layer, and a metal outer shell layer.

[0011] In a further embodiment, a sealing strip is attached to the side of the cover plate.

[0012] In a further embodiment, the fixing ring has a through hole at its center for the torch head to pass through, and the fixing ring is fixedly connected to the outer wall of the torch head.

[0013] In a further embodiment, a corrugated telescopic cover is installed between the fixed ring and the screw ring, and between the screw ring and the fixed base, and the corrugated telescopic cover completely covers the screw cylinder.

[0014] In a further embodiment, an anemometer is also included, and both the anemometer and the motor are externally connected to a control system.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention controls the opening and closing of the movable cover through a motor-driven transmission mechanism. In windless and rainless weather, the cover is fully open to ensure complete combustion of the torch flame, smooth heat dissipation, and avoid black smoke and energy waste caused by incomplete combustion. In strong winds or heavy rain, the cover can be closed or adjusted to a suitable angle to effectively reduce the direct impact of wind and rain on the flame, stabilize combustion conditions, and thus significantly reduce the direct emission of greenhouse gases such as methane and pollutants caused by flameout or low combustion efficiency.

[0017] The invention features a movable cover composed of multiple circumferentially symmetrical hinged panels. When closed, it forms a sealed space resembling an "umbrella" or "petal". Combined with the sealing strip design on the side of the cover panels, it greatly improves the overall sealing performance and can effectively resist the invasion of wind and rain from all directions, especially oblique wind and rain, preventing the flame from being blown off or extinguished by rain, thus ensuring high safety.

[0023] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Please see Figure 1-4 An energy-saving natural gas extraction flare adjustment device is provided. The device is installed outside the flare head 1 of the flare system. The fixed base 2 is fixedly installed at a suitable position on the flare tower by a plurality of L-shaped legs 21 at its bottom. The flare head 1 is protruding from the center of the fixed base 2. The fixing ring 33 is sleeved and fixedly connected to the outer wall of the flare head 1 through the through hole in its center.

[0027] The movable cover 3 consists of six identical cover plates 31 (which can be more or fewer as needed) circumferentially hinged to the fixing ring 33. In this embodiment, the cover plates 31 form an umbrella-shaped structure when closed. Each cover plate 31 is composed of an aluminum foil layer, a ceramic fiber felt layer, and a metal outer shell layer from the inside out, which has excellent high temperature resistance, heat insulation, and structural strength. To ensure the sealing when closed, a high temperature resistant sealing strip 34 is installed on the mating side of adjacent cover plates 31.

[0028] A connecting plate 32 is fixedly connected to the lower end of the hinge point of the cover plate 31. Between the fixed base 2 and the fixed ring 33, a screw cylinder 4 is rotatably installed through a bearing (not shown in the figure). A screw ring 5 is screwed to the external thread of the screw cylinder 4 through its internal thread. A support rod 6 is hinged to each connecting plate 32 through a hinge seat on the periphery of the screw ring 5. The other end of the support rod 6 is hinged to the corresponding connecting plate 32.

[0029] The drive unit includes a motor 9 fixedly mounted on a fixed base 2. The output shaft of the motor 9 is connected to a worm 8. A worm wheel ring 7 is coaxial with the screw barrel 4 and fixedly connected through a keyway. The worm wheel ring 7 meshes with the worm 8, forming a drive mechanism with a self-locking function.

[0030] To prevent environmental impurities from corroding the transmission components, corrugated telescopic covers 10 are installed between the fixed ring 33 and the screw ring 5, and between the screw ring 5 and the fixed base 2, to completely cover the entire screw barrel 4, screw ring 5 and drive mechanism, forming a protective layer.

[0031] In addition, an anemometer 11, such as an ultrasonic anemometer, is installed near the torch head 1. Both the anemometer 11 and the motor 9 are connected to the platform's control system, such as a PLC or DCS system, via cables.

[0032] Working principle: When the anemometer 11 detects an increase in wind speed or the control system receives a rainfall signal, the control system sends a command to the motor 9. The motor 9 starts, driving the worm gear 8 to rotate. The worm gear 8 drives the worm wheel ring 7, which meshes with it, to rotate. This causes the screw cylinder 4, which is fixed to the worm wheel ring 7, to rotate synchronously. Since the screw ring 5 is fitted onto the screw cylinder 4 through a threaded pair and is constrained from rotating, the rotation of the screw cylinder 4 is converted into the upward linear motion of the screw ring 5. The screw ring 5 moves upward and pushes all the connecting plates 32 through the support rod 6, which is hinged to it. The connecting plates 32 drive all the cover plates 31 to rotate synchronously inward around their hinge point with the fixed ring 33, so that the movable cover 3 gradually closes, reducing the ventilation opening and providing an effective protective space for the torch flame. Conversely, when the wind and rain weaken, the motor 9 rotates in the opposite direction, driving the screw ring 5 to move downward. Through the support rod 6, the connecting plate 32 is pulled, so that all the cover plates 31 rotate outward synchronously and open, restoring the torch head 1 to a fully open state and ensuring unobstructed combustion.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
