Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of offshore industrial equipment, in particular to an anti-sloshing gas-liquid separator device for a marine fluctuating environment. BACKGROUND

[0002] With the increasing demand for green energy worldwide, using marine renewable energy (such as wind energy, solar energy) to electrolyze water to produce hydrogen is considered a promising clean energy solution. Deploying an electrolytic hydrogen production system on an offshore platform or a ship can directly utilize abundant offshore renewable energy and achieve on-site production of hydrogen energy. The gas-liquid mixture produced by electrolysis needs to be efficiently separated in a gas-liquid separator to obtain high-purity hydrogen or oxygen.

[0003] Traditional gas-liquid separators for electrolytic hydrogen production systems are usually designed based on stable land environments. In marine platform or ship application scenarios, continuous rolling, pitching, and heaving movements will cause the liquid level in the gas-liquid separator to fluctuate dramatically, leading to a series of problems. Large fluctuations in the liquid level can seriously affect the gas-liquid separation effect, possibly causing liquid to be entrained in the separated gas or allowing liquid to enter the gas output pipeline, resulting in reduced gas purity and possibly causing damage to downstream compression, storage, and use equipment or even safety accidents. Conventional rigid support structures cannot effectively buffer the energy transmitted from the foundation to the tank, exacerbating overall instability.

[0004] In the prior art, anti-sloshing plates are provided in the tank to reduce the impact of liquid sloshing. For example, patent number CN223328255U discloses a "liquid storage tank with anti-sloshing function", which solves the technical problem of liquid sloshing affecting transportation stability by providing multiple anti-sloshing plates with flow passages in the liquid storage tank. However, this type of solution does not fully consider the particularity of gas-liquid separators. During gas-liquid separation, both liquid and gas need to maintain continuous flow states, making it difficult to directly apply to gas-liquid separation scenarios and unable to meet the high-efficiency separation requirements. SUMMARY

[0005] To address the deficiencies of the prior art, the present application provides an anti-sloshing gas-liquid separator device for a marine fluctuating environment to solve the above problems.

[0006] The present application provides the following technical solutions: An anti-sloshing gas-liquid separator device for a marine fluctuating environment, comprising a tank body with an exhaust port, a liquid inlet, and a liquid outlet, a left baffle and a right baffle are arranged in the inner cavity of the tank body between the liquid inlet and the liquid outlet, and the left baffle and the right baffle are arranged alternately left and right along the longitudinal axis direction of the tank body. A flexible hole net is arranged between the adjacent left baffle and right baffle, and extends from the left sidewall of the tank to the right sidewall along the contour of the lower part of the tank cross section. A telescopic rod is connected to the middle part of the upper edge of the flexible hole net.

[0007] Preferably, the tank has a whole shape of a hollow cylindrical body without edges, and the outer wall is provided with an anticorrosive coating layer.

[0008] Preferably, the outer pipe connected to the liquid inlet and liquid outlet of the tank is made of flexible and strong alkali corrosion resistant material.

[0009] Preferably, the left baffle and right baffle are both provided with a flow channel between the tank inner bottom wall, and the left baffle and right baffle are both lower than the tank inner top wall.

[0010] Preferably, the flexible hole net is made of flexible polymer mesh resistant to alkali corrosion.

[0011] Preferably, the tank bottom is provided with a bottom support spring buffer for reducing the shaking amplitude of the tank along the column length direction, and the outer wall of the tank is provided with a lateral buffer spring assembly at the height position of the center of gravity for inhibiting and reducing the shaking amplitude of the tank along the diameter direction.

[0012] Preferably, the left and right side edges of the flexible hole net are respectively fixed to the left and right sides of the tank inner wall, and the horizontal height is higher than the left baffle and right baffle.

[0013] Preferably, the flexible hole net has a porosity range of 0.6-0.75, and a pore diameter range of 2mm-5mm.

[0014] Preferably, the telescopic rod is an elastic telescopic rod with a length tending to shorten, and is installed on the tank; or The length of the telescopic rod is fixed and fixed on the foundation, the tank is installed on the foundation through a buffer support device, and one end of the telescopic rod is movably penetrated into the tank.

[0015] Preferably, the tank bottom is provided with a monitoring gyroscope, and the monitoring gyroscope sends an alarm signal when reaching a preset critical value.

[0016] The present application has the following beneficial technical effects: When the tank is shaken by the external marine environment, the flexible hole net is self-adapting and telescopic with the liquid surface shaking, and the dynamic inhibition of the fluid movement in the tank is realized through the cooperation of the telescopic rod and the flexible hole net, which is an active adjustment mode of "soft overcomes hard".

[0017] By designing the gas-liquid separator tank body as a hollow cylindrical body without corners and internally arranging the left and right baffles in a staggered manner, in combination with the bottom support spring assembly and the lateral buffer spring assembly at the bottom and sides of the tank, a passive mechanical anti-sloshing structure is constructed, which can significantly physically attenuate and absorb the energy transmitted from the ocean waves, effectively inhibiting the violent sloshing and impact of the liquid in the tank.

[0018] At the same time, the monitoring gyroscope integrated in the tank body can sense the sloshing amplitude in real time and timely alarm when reaching the critical value, providing a key safety warning window for the operator. This multiple safety guarantee mechanism of "passive inhibition + active regulation + real-time warning" greatly enhances the adaptability and reliability of the equipment in severe sea conditions.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Embodiment: A kind of anti-sloshing gas-liquid separator device for ocean wave environment, such as Figures 1-7As shown, it comprises a gas-liquid separator tank 1, a buffer support device 2 and a liquid level flexible adjustment and early warning module 3.

[0023] The gas-liquid separator tank 1 comprises a tank body 11, an exhaust port 12, a liquid inlet port 13, a liquid outlet port 14, a left baffle 15 and a right baffle 16. The tank body 11 is used for gas-liquid sedimentation separation, and has a whole shape of a hollow cylindrical body without edges and corners. An outer wall is sprayed with a corrosion-resistant coating layer (such as an epoxy zinc-rich primer combined with a polyurethane topcoat) to avoid tank corrosion caused by sea spray and salt mist. The tank body 11 is made of high-strength alloy steel to withstand internal pressure and liquid impact force caused by shaking. The exhaust port 12 is used for discharging separated hydrogen or oxygen, and is arranged on the top wall of the tank body 11 and close to the liquid outlet port 14. The exhaust port 12 is connected with a subsequent hydrogen / oxygen purification system through a pipeline. The liquid inlet port 13 is used for introducing lye containing gas. The corresponding external pipeline is made of flexible and strong alkali corrosion-resistant material (such as fluororubber or polytetrafluoroethylene PTFE composite material). The external pipeline is coupled with the liquid inlet port 13 of the tank body 11 by using a flexible flange. The liquid outlet port 14 is used for discharging lye after gas-liquid separation. The corresponding external pipeline is made of flexible and strong alkali corrosion-resistant material (such as fluororubber or polytetrafluoroethylene PTFE composite material). The external pipeline is coupled with the liquid outlet port 14 of the tank body 11 by using a flexible flange. The liquid inlet port 13 and the liquid outlet port 14 are oppositely arranged at the left and right ends of the tank body 11.

[0024] The flexible flange can contain a rubber sealing ring or a corrugated structure inside to allow a certain displacement and deflection of the external pipeline in multiple directions, so as to isolate the direct stress of the hull or platform shaking on the tank body 11 interface.

[0025] The left baffle 15 and the right baffle 16 are used to reduce the fluctuation amplitude of the liquid level in the shaking state. The left baffle 15 and the right baffle 16 are arranged in a staggered manner along the axial direction of the tank body 11, so as to realize the zigzag flow of the liquid in the longitudinal direction (axial direction) of the tank body 11 and reduce the liquid impact in the tank body 11 caused by shaking.

[0026] The left baffle 15 is fixed on the left inner wall of the tank body 11 from top to bottom, but the lower end of the left baffle 15 does not contact the bottom of the tank body 11, leaving a flow passage. The upper end of the left baffle 15 is lower than the tank top of the tank body 11 and is oppositely arranged at the middle position of the tank body 11. Similarly, the right baffle 16 is fixed on the right inner wall of the tank body 11. The left baffle 15 and the right baffle 16 partially overlap along the axial direction of the tank body 11. Such staggered arrangement forces the liquid to flow longitudinally along a zigzag path in the tank body 11, greatly increases the flow resistance, effectively consumes the kinetic energy of liquid shaking, and thus significantly reduces the large amplitude impact and sloshing of the liquid surface caused by ocean waves.

[0027] The buffer support device 2 includes a bottom support spring assembly 21 and a lateral buffer spring assembly 22. The bottom support spring assembly 21 uses a high elastic modulus spring, whose stiffness is sufficient to stably support the static load of the tank 11 and its internal medium. The bottom of the tank 11 is mounted on the foundation by evenly arranging multiple bottom support spring assemblies 21. When the foundation (such as a ship deck) experiences vertical or longitudinal swaying, the compression and rebound of the bottom support spring assembly 21 itself absorbs most of the vibration energy, significantly reducing the swaying amplitude of the tank 11 along the column length direction (vertical or longitudinal direction). Multiple sets of lateral buffer spring assemblies 22 are evenly arranged around the circumference of the tank 11 and are located near the center of gravity height of the tank 11. One end of the lateral buffer spring assembly 22 is connected to the outer wall of the tank 11, and the other end is fixed to the rigid support of the surrounding foundation. When the tank 11 attempts to swing in the horizontal plane due to the ship's roll and pitch, the lateral buffer spring assembly 22 will provide restoring force, suppressing and reducing the swaying amplitude of the tank 11 along the diameter direction (i.e., lateral).

[0028] The liquid level flexible adjustment and early warning module 3 includes a telescopic rod 31, a flexible perforated mesh 32, and a monitoring gyroscope 33.

[0029] The flexible perforated mesh 32 can be made of alkali-resistant flexible polymer mesh, such as nylon or ultra-high molecular weight polyethylene woven mesh, which has a certain degree of elasticity and small mesh size. The two edges of the flexible perforated mesh 32 are fixed to the left and right sides of the inner wall of the tank 11, respectively. Figure 7 The two sides of the flexible perforated mesh 32 shown are located above the left baffle 15 and the right baffle 16 or in the intersecting space, and the flexible perforated mesh 32 (partially folded for easy unfolding) extends from the left side of the tank 11 along the lower part of the cross section of the tank 11 (perpendicular to the length and axial direction of the tank 11) to the right side wall.

[0030] Because the flexible perforated mesh 32 has a relatively dense mesh, it does not obstruct the center of the tank 11 under normal conditions. When the environment is relatively stable, the flexible perforated mesh 32 itself is relatively low in height, so it does not affect the free settling and mixing of the liquid in the tank 11. If the flexible perforated mesh 32 is placed in the tank 11 at a relatively high height (obstructing the center of the tank 11) for a long time, its holes are prone to blockage, which will affect the normal settling and mixing of the liquid in the tank 11.

[0031] In one configuration of the telescopic rod 31, the length of the telescopic rod 31 is fixed and it is fixed to the foundation. A through hole is provided at the bottom of the tank body 11. One end of the telescopic rod 31 passes through the through hole at the bottom of the tank body 11 and enters the interior of the tank body 11, connecting to the middle of the upper edge of the flexible perforated mesh 32. A flexible sealing ring is provided between the through hole at the bottom of the tank body 11 and the telescopic rod 31 to achieve a seal without affecting the relative movement between the telescopic rod 31 and the tank body 11. With the length of the telescopic rod 31 fixed, it allows for telescopic movement within the tank body 11 as the tank body 11 moves relative to the foundation.

[0032] The second mode of the telescopic rod 31 is that the telescopic rod 31 is flexible and can be telescoped up and down, and the telescopic rod 31 can adopt a multi-section sleeve structure or a bellows structure to ensure that it can be telescoped up and down in the axial direction. The elastic telescopic rod tends to be shortened in the normal state, and the fixed end of the telescopic rod 31 is installed on the tank body 11, and the movable end of the telescopic rod 31 is connected with the middle part of the upper edge of the flexible hole net 32.

[0033] When the tank body 11 shakes, the telescopic rod 31 will be telescoped up and down in the tank body 11 relative to the tank body 11 under the action of the liquid pushing force and its own gravity. The telescopic rod 31 drives the flexible hole net 32 to be telescoped in the tank together with the shaking of the tank body 11, so as to change the width of the flexible hole net 32 and realize the change of the width of the flexible hole net 32 to block the center position of the tank body 11, wherein the flexible hole net 32 will limit the flow of the liquid generated by the shaking tank body 11. In this way, the flexible hole net 32 is lifted only when the tank body 11 shakes, and the liquid flow is blocked to form the liquid tank oscillation phenomenon.

[0034] The holes of the flexible hole net 32 allow gas and liquid to pass normally to maintain the separation process, but the mesh structure of the flexible hole net 32 forms a physical barrier to the macro flow of the liquid, and when the mesh structure of the flexible hole net 32 moves with the telescopic rod 31, when the tank body 11 shakes to one side, the mesh structure of the flexible hole net 32 will be lifted on that side, realizing adaptive and flexible adjustment, further limiting the violent shaking of the liquid, and playing the role of an “internal damper”.

[0035] The monitoring gyroscope 33 is installed at the bottom of the tank body 11, and the monitoring gyroscope 33 can monitor the attitude angle change (such as roll angle and pitch angle) and / or angular velocity of the tank body 11 in space in real time and dynamically. In the system control unit, a shaking amplitude critical value reflecting the safety operation limit (for example, the inclination angle of the tank body exceeds 5 degrees or the angular velocity exceeds a certain threshold value) is set in advance. The monitoring gyroscope 33 continuously transmits the collected shaking data to the control unit. Once it is monitored that the shaking amplitude reaches or exceeds the set critical value, the control unit immediately triggers the alarm system. Through the on-site warning and alarm signal remote transmission to the central control room, the two ways of warning and alarm signal together warn and prompt the operator to pay close attention to the operation state of the hydrogen production system or take necessary stabilizing measures or shut down the machine.

[0036] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
