Description

Technical fields:

[0001] This invention relates to the field of filtration device design, and in particular to a marine adjustable fixed air intake filtration device and the vessel thereof. Background technology:

[0002] The marine atmosphere is complex, characterized by high humidity and high salt spray. Unfiltered air entering the intake passage can corrode components such as the compressor, combustion chamber, and turbine blades, thereby reducing the efficiency of the gas turbine and even causing power outages and affecting its service life. Therefore, it is essential to use an air-water separator to filter the intake airflow, ensuring that the gas turbine receives sufficient clean air and that the ship can navigate in all weather conditions.

[0003] There is an urgent need for a marine adjustable fixed air intake filter device, which would help solve the technical problem of the lack of a filter device to overcome poor air filtration quality in the existing technology. Summary of the Invention:

[0004] In one embodiment, the present invention provides a marine adjustable fixed air intake filter device that filters air through a multi-layered filter structure and de-ices the air by heating the anti-icing frame, thereby ensuring that the first and second side mesh pads open smoothly. This helps to solve the technical problem of the lack of a filter device in the prior art to overcome the poor air filtration quality.

[0005] The marine adjustable fixed air intake filter includes a door frame housing, a front inertial stage, a mesh pad, a rear inertial stage, and a heated anti-icing frame.

[0006] The mesh pad has a first side mesh pad and a second side mesh pad that can be opened to both sides;

[0007] The front inertial stage, the heated anti-icing frame, the mesh pad, and the rear inertial stage are disposed in the door frame housing.

[0008] In one embodiment, hexagonal prisms are respectively provided at the upper and lower ends of both sides of the mesh pad, so that the first side mesh pad and the second side mesh pad are rotatably connected to the door frame housing.

[0009] In one embodiment, the rotating side of the first side mesh pad has an arc-shaped structure, and the other side of the first side mesh pad has a serrated structure, so as to be fixed after abutting against the serrated structure corresponding to the second side mesh pad.

[0010] In one embodiment, the front inertial stage and the rear inertial stage are fixed to the door frame housing by snap-fit.

[0011] In one embodiment, the marine adjustable fixed air intake filter further includes a rotator and a pneumatic adjustment device, as well as a control device;

[0012] The rotator, the pneumatic adjustment device, and the control device are used to control the opening angle and direction of the first side mesh pad and the second side mesh pad.

[0013] In one embodiment, the heated anti-icing frame includes a temperature sensor and an electric heating wire;

[0014] The temperature sensor monitors the edge temperature of the first side mesh and the second side mesh in real time. When the temperature is lower than the preset lower threshold, the electric heating wire is automatically turned on to heat the first side mesh and the second side mesh. When the temperature of the marine adjustable fixed air intake filter reaches the upper threshold, the heating ends.

[0015] In one embodiment, the marine adjustable fixed air intake filter further includes a differential pressure sensor;

[0016] The differential pressure sensor is used to monitor the pressure difference between the two ends of the fixed intake air filter in real time.

[0017] In one embodiment, when the pressure drop reaches the alarm state, the number of rotations and the angle of the first side net mat and the second side net mat can be selected using the control device. After the pressure drop returns to normal, the net mat state can be selected again according to the actual navigation conditions.

[0018] In one embodiment, the ship's air-water separator uses the aforementioned marine adjustable fixed air intake filter to filter and clean the air. Attached image description:

[0046] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Various embodiments and features of this application are described herein with reference to the accompanying drawings.

[0048] These and other features of this application will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0049] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0050] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0051] Specific embodiments of this application are described below with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0052] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0053] The exhaust air from the air conditioning system cabins is directly discharged to the outdoor atmosphere after heat recovery by the heat wheel. Its temperature is generally no more than 28°C and it is not reused, resulting in a large amount of energy loss.

[0054] The ship's air-water separator consists of an adjustable louver 10, a fixed air intake filter 20, and an openable air intake filter (emergency bypass device) 30 before entering the combustion chamber. The openable air intake filter is equivalent to the marine adjustable fixed air intake filter discussed in this invention. The fixed air intake filter 20, compared to the openable air intake filter (emergency bypass device) 30, incorporates a mesh filter, significantly improving air-water separation capability. The adjustable louver 10 can be opened and closed, preventing large-diameter droplets from entering the air intake channel. The airflow passes through the fixed air intake filter 20 and the openable air intake filter (emergency bypass device) 30 before entering the combustion chamber.

[0055] Under normal navigation conditions, the open-type air intake filter (emergency bypass device) 30 is in the closed state. It is opened in an emergency, at which time some gas enters the gas turbine directly without being fully filtered, ensuring the ship's power supply.

[0056] The open-type air intake filter (emergency bypass device) 30 mostly adopts an integrated switch structure and is added near the device 20, increasing the size and weight of the air intake and air-water separator. The independent emergency bypass device 30 complicates the arrangement of the air-water separator on the hull, affecting the ship's aesthetics and stealth performance. In addition, the device 30 has a small air intake volume and poor air quality, which cannot meet the requirements of long-term, high-efficiency operation of the ship.

[0059] like Figures 1 to 9 As shown, in one embodiment, the present invention provides a marine adjustable fixed air intake filter device, the marine adjustable fixed air intake filter device including a door frame housing 1, a front inertial stage 2, a mesh pad 3, a rear inertial stage 4, and a heated anti-icing frame 5;

[0060] The mesh pad 3 has a first side mesh pad 31 and a second side mesh pad 32 that can be opened to both sides;

[0061] The front inertial stage 2, the heated anti-icing frame 5, the mesh pad 3, and the rear inertial stage 4 are installed in the door frame housing 1.

[0062] This embodiment provides a specific structure for a marine adjustable fixed air intake filter device. The front inertial stage 2, mesh pad 3, and rear inertial stage 4 are all mesh filter structures. Unlike existing technologies, their arrangement and the mesh pad 3's openable design on both sides allow for outward opening via the first side mesh pad 31 and the second side mesh pad 32. The front inertial stage 2, the rotating first side mesh pad 31 and the second side mesh pad 32, and the rear inertial stage 4 are sequentially installed inside the door frame housing 1. A heated anti-icing frame 5 is installed between the first side mesh pad 31, the second side mesh pad 32, and the door frame housing 1. The first side mesh pad 31 and the second side mesh pad 32 cannot rotate due to condensation and freezing. Furthermore, the use of a flexible connection structure enhances the device's sealing performance, helping to solve the technical problem of the lack of a filter device in the prior art to overcome poor air filtration quality.

[0063] In one embodiment, hexagonal prisms 33 are respectively provided at the upper and lower ends of both sides of the mesh pad 3, so that the first side mesh pad 31 and the second side mesh pad 32 are rotatably connected to the door frame housing 1.

[0064] This embodiment provides a specific implementation method for installing and fixing the mesh pad 3. The first side mesh pad 31 and the second side mesh pad 32 have completely identical structures and functions, and open in the same direction. The upper and lower left edges of the mesh pad 3 are provided with two hexagonal prism structures 11 of the same size for the installation, fixing and rotation of the mesh pad.

[0065] In one embodiment, the rotating side of the first side mesh pad 31 has an arc-shaped structure, and the other side of the first side mesh pad 31 has a serrated structure, so as to be fixed after being abutted against the serrated structure corresponding to the second side mesh pad 32.

[0066] In this embodiment, an arc-shaped structure is provided on the outer side of the first side mesh pad 31 to facilitate the rotation of the first side mesh pad 31, and the other layer is a sawtooth structure. When the second side mesh pad 32 is set with the corresponding sawtooth structure, the sawtooths engage after they abut against each other, and the connection and fixation of the first side mesh pad 31 and the second side mesh pad 32 are achieved so as to achieve a better filtration effect.

[0067] In one embodiment, the front inertial stage 2 and the rear inertial stage 4 are fixed to the door frame housing 1 by means of a snap fastener 6.

[0068] This embodiment provides a specific implementation method for connecting the front inertial stage 2 and the rear inertial stage 4 via a snap-fit ​​6. The snap-fit ​​6 is used to fix the rear front inertial stage 2 and the rear inertial stage 4 to the rear and front sides of the door frame housing 1, respectively, with sufficient space between the two devices for the first side mesh pad 31 and the second side mesh pad 32.

[0069] In one embodiment, the marine adjustable fixed air intake filter further includes a rotator 6, a pneumatic adjustment device 7, and a control device 8;

[0070] Rotator 6, pneumatic adjustment device 7, and control device 8 are used to control the opening angle and direction of the first side mesh pad 31 and the second side mesh pad 32.

[0071] This embodiment provides a specific implementation method for controlling the opening angle and direction of the first side mesh pad 31 and the second side mesh pad 32 through a rotator 6, a pneumatic adjustment device 7, and a control device 8. The heating and anti-icing device 5 is bolted to the door frame housing 1. To achieve better de-icing, the width of the heating and anti-icing device 5 is consistent with the rotation width of the mesh pad 3. Holes are provided on the upper, lower, and left sides of the rear inertial stage 4 to facilitate the connection of the hexagonal prism 33 to the door frame housing 1. A rotator 6 is provided at a corresponding position on the door frame housing 1. The rotator 6 has an internal hexagonal rotating structure. The rotator 6 is connected to the pneumatic adjustment device 7 and the control device 8 to control the rotation angle and direction of the first side mesh pad 31 and the second side mesh pad 32. A manual rotator may also be included for emergency adjustments in case of electrical control device failure, enhancing the reliability of the equipment.

[0072] In one embodiment, the heated anti-icing frame 5 includes a temperature sensor 51 and an electric heating wire 52;

[0073] Temperature sensor 51 monitors the edge temperature of the first side mesh pad 31 and the second side mesh pad 32 in real time. When the temperature is lower than the preset lower threshold, electric heating wire 52 automatically turns on to heat the first side mesh pad 31 and the second side mesh pad 32. When the temperature of the marine adjustable fixed air intake filter reaches the upper threshold, the heating ends.

[0074] This embodiment provides a specific structure for a heated anti-icing frame 15.

[0075] In one embodiment, the marine adjustable fixed air intake filter further includes a differential pressure sensor 9;

[0076] Differential pressure sensor 9 is used to monitor the pressure difference between the two ends of the filter device at the fixed intake in real time.

[0077] This embodiment provides a specific implementation method for real-time monitoring of the air pressure difference across the fixed intake filter using a differential pressure sensor 9.

[0078] In one embodiment, when the pressure drop reaches the alarm state, the number of rotations and the angle of the first side net pad 31 and the second side net pad 32 can be selected using the control device. After the pressure drop returns to normal, the net pad state can be selected again according to the actual navigation conditions.

[0079] In this embodiment, a specific implementation method under alarm state is provided. The opening of the first side mesh pad 31 and the second side mesh pad 32 can be adjusted automatically or manually. The differential pressure sensor 19 monitors the air pressure difference between the two ends of the fixed air intake filter at all times. When the pressure drop reaches the alarm state, the number of rotations and the angle of the first side mesh pad 31 and the second side mesh pad 32 can be selected by the control device 8. When the pressure drop returns to normal, the mesh pad state is selected again according to the actual navigation conditions.

[0080] In one embodiment, the present invention provides a ship that uses the aforementioned adjustable fixed air intake filter, wherein the ship's air-water separator uses the aforementioned adjustable fixed air intake filter to filter and clean the air.

[0081] In this embodiment, a specific implementation method for applying a marine adjustable fixed air intake filter device on a ship is provided.

[0082] Beneficial effects:

[0083] The advantages of this invention are that it incorporates a rotating air intake mesh within a fixed filter, enabling dynamic control of the air pressure drop within the intake duct and achieving continuous and stable air intake for ships under complex conditions. The marine adjustable fixed air intake filter combines filtration and bypass functions, reducing the number of shipboard devices, optimizing the intake device layout, minimizing hull openings, increasing the overall structural strength of the hull, and improving the reliability of the intake device under frigid conditions. This device is equipped with a differential pressure sensor, a pneumatic adjustment device, and a control device, enabling automatic or manual adjustment of the air intake, achieving a dynamic balance between intake flow and pressure drop, and enhancing the environmental adaptability of the intake device.

[0084] Based on the above structure, the marine adjustable fixed air intake filter device will be further described in detail:

[0085] Door frame housing 1, front inertia stage 2, left first side mesh pad with rotation function 31, right second side mesh pad with rotation function 32, rear inertia stage 4, heated anti-icing frame 5, pneumatic adjustment device 7, differential pressure sensor 9, and control device 15.

[0086] The first side mesh pad 31 and the second side mesh pad 32 are connected to the heating and anti-icing frame 5 and the door frame housing 1 via hexagonal prisms 33. The opening and closing actuator 101 is linked with the differential pressure sensor 9, the pneumatic adjustment device 10, and the control device 8. The rotation direction and amplitude of the actuator 101 can be controlled manually or automatically to regulate the airflow. When the intake airflow pressure drop is greater than a preset value, the control device 8 alarms. When the pressure drop is greater than a threshold, the actuator 101 rotates automatically, and both the first side mesh pad 31 and the second side mesh pad 32 open automatically. When the pressure drop is lower than the preset value, the second side mesh pad 32 closes. If the pressure drop remains below the preset value for 5 minutes, the first side mesh pad 31 automatically closes. During this process, the opening and rotation angle of the first side mesh pad 31 and the second side mesh pad 32 can be controlled manually.

[0087] The heated anti-icing frame 5 consists of a temperature sensor 51 and an electric heating wire 52, which is installed between the first side mesh pad 31, the second side mesh pad 32, and the door frame housing 1. When the temperature is lower than the temperature threshold, the electric heating wire 52 works, and when the temperature rises to the preset value, the electric heating wire 52 stops working, ensuring that the first side mesh pad 31 and the second side mesh pad 32 can still open and close freely under severe cold conditions, thus improving the overall reliability of the equipment.

[0088] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
