Description

Technical field:

[0001] The invention relates to the field of filter device design, in particular to an adjustable fixed air intake filter device for a ship and a ship thereof. Background technology:

[0002] The marine atmosphere is complex, with high humidity, high salt fog and other characteristics. Unfiltered air entering the air intake passage will corrode the compressor, combustion chamber, turbine blades and other components, thereby reducing the efficiency of the gas turbine and even causing the ship's power to be interrupted and affecting its service life. Therefore, an air-water separator must be used to filter the intake air flow to ensure that the gas turbine obtains sufficient pure air and that the ship can sail in all-weather conditions.

[0003] There is an urgent need for an adjustable fixed air intake filter device for ships, which helps to solve the technical problem that the prior art lacks a filter device to overcome the poor air filtration quality. Summary of the invention:

[0004] In one embodiment, the present invention provides an adjustable fixed air intake filter device for ships, which filters the air through a multi-layer filtering structure and de-ices by heating the anti-icing frame to ensure smooth opening of the first side mesh pad and the second side mesh pad, thereby helping to solve the technical problem that the prior art lacks a filtering device to overcome the poor air filtration quality.

[0005] The marine adjustable fixed air intake filter device comprises a door frame housing, a front inertia stage, a mesh pad, a rear inertia stage, and a heating anti-icing frame;

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

[0007] The front inertia stage, the heating anti-icing frame, the mesh pad, and the rear inertia stage are arranged in the door frame shell.

[0008] In one embodiment, hexagonal columns 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 can be rotatably connected to the door frame shell.

[0009] In one embodiment, one side of the first side mesh pad is an arc-shaped structure, and the other side of the first side mesh pad is a sawtooth structure, so as to be fixed after being abutted against the corresponding sawtooth structure of the second side mesh pad.

[0010] In one embodiment, the front inertia stage and the rear inertia stage are fixed to the door frame shell by snap fastenings.

[0011] In one embodiment, the marine adjustable fixed air intake filter device further comprises a rotator and a pneumatic adjustment device, and 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 pad and the second side mesh pad in real time. When the temperature is lower than a preset lower threshold, the electric heating wire automatically turns on to heat the first side mesh pad and the second side mesh pad. When the temperature of the marine adjustable fixed air intake filter device reaches an upper threshold, the heating ends.

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

[0016] The pressure difference sensor is used to monitor the air pressure difference at both ends of the fixed air intake filter device in real time.

[0017] In one embodiment, when the pressure drop reaches an alarm state, the control device can be used to select the rotation number and angle of the first side mesh pad and the second side mesh pad. When the pressure drop returns to normal, the mesh pad state is selected again according to actual navigation conditions.

[0046] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

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

[0048] These and other characteristics of the present application will become apparent from the following description of a preferred form of embodiment given as a non-limiting example with reference to the accompanying drawings.

[0049] It should also be understood that, although the present application has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present application that have the features described in the claims and are therefore within the scope of protection defined thereby.

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

[0051] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to determine the true intent based on the user's historical operations and to avoid unnecessary or redundant details that make the present application unclear. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but are merely used as the basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of 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 the present application.

[0053] The cabin exhaust air of the air-conditioning system is directly discharged to the outdoor atmosphere after heat recovery by the heat wheel. Its temperature generally does not exceed 28°C and is not reused, resulting in a large amount of energy loss.

[0054] The gas-water separator of the ship enters the combustion chamber after being connected to the adjustable shutter 10, the fixed air intake filter device 20 and the open air intake filter device (emergency bypass device) 30, wherein the open air intake filter device is equivalent to the ship-used adjustable fixed air intake filter device discussed in the present invention, and the fixed air intake filter device 20 is equipped with a mesh filter device compared to the open air intake filter device (emergency bypass device) 30, which greatly improves the gas-water separation capacity. The adjustable shutter 10 can be opened and closed to block large-size droplets from entering the intake channel, and the intake air flows through the fixed air intake filter device 20 and the open air intake filter device (emergency bypass device) 30 and enters the combustion chamber.

[0055] Under normal sailing conditions, the open air intake filter device (emergency bypass device) 30 is in a closed state and is opened in an emergency. At this time, part of the gas directly enters the gas turbine without being fully filtered to ensure the power supply of the ship.

[0056] The open air intake filter device (emergency bypass device) 30 mostly adopts an integral switch structure and is added near the device 20, which increases the size and weight of the air intake duct and the air-water separator. The independent emergency bypass device 30 complicates the arrangement of the air-water separator on the hull, affecting the aesthetics and stealth performance of the ship. In addition, the device 30 has a small air intake volume and poor air quality, which cannot meet the requirements of long-term and 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 comprises a door frame shell 1, a front inertia stage 2, a mesh pad 3, a rear inertia stage 4, and a heating anti-icing frame 5;

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

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

[0062] In this embodiment, a specific structure of a marine adjustable fixed air intake filter device is provided. The front inertia stage 2, the mesh pad 3, and the rear inertia stage 4 are all mesh filter structures. Different from the prior art, their arrangement order and the mesh pad 3 adopt a structural design that can be opened on both sides, and the first side mesh pad 31 and the second side mesh pad 32 are used to open outward. The front inertia stage 2, the first side mesh pad 31 and the second side mesh pad 32 with a rotation function, and the rear inertia stage 4 are sequentially installed in the door frame shell 1, and the heating anti-icing frame 5 is installed between the first side mesh pad 31 and the second side mesh pad 32 and the door frame shell 1. The first side mesh pad 31 and the second side mesh pad 32 cannot rotate due to the freezing of condensed water. On the other hand, the soft connection structure is used to enhance the sealing performance of the device, which helps to solve the technical problem that the prior art lacks a filtering device to overcome the poor air filtration quality.

[0063] In one embodiment, hexagonal columns 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 can be rotatably connected to the door frame housing 1 .

[0064] In this embodiment, a specific implementation method for installing and fixing the mesh pad 3 is provided. The first side mesh pad 31 and the second side mesh pad 32 have completely identical structures and the same functions, and are opened in the same direction. Two hexagonal prism structures 11 of the same size are provided at the left edges of the upper and lower sides of the mesh pad 3 for installing, fixing and rotating the mesh pad.

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

[0066] In this embodiment, an arc structure is provided on the outer side of a first side mesh pad 31 to facilitate the rotation of the first side mesh pad 31, and the other layer is a serrated structure. When the second side mesh pad 32 is set to a corresponding serrated structure, the serrated teeth are engaged after being matched and offset, and the first side mesh pad 31 and the second side mesh pad 32 are connected and fixed to achieve a better filtering effect.

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

[0068] In this embodiment, a specific implementation method of connecting the front inertia stage 2 and the rear inertia stage 4 by means of the buckle 6 is provided. The front inertia stage 2 and the rear inertia stage 4 are fixed to the rear side and the front side of the door frame shell 1 by means of the buckle 6, respectively, and sufficient space is left 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 device further includes a rotator 6 and a pneumatic adjustment device 7, and a control device 8;

[0070] The rotator 6 , the pneumatic adjustment device 7 , and the 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] In this embodiment, a specific implementation method is provided for controlling the opening angle and direction of the first side mesh pad 31 and the second side mesh pad 32 by means of a rotator 6, a pneumatic adjustment device 7, and a control device 8. The heating and anti-icing device 5 is connected to the door frame shell 1 by bolts. To achieve a better deicing effect, the width of the heating and anti-icing device 5 is consistent with the rotation width of the mesh pad 3. Holes are left on the upper and lower left sides of the rear inertia stage 4 to facilitate the connection of the hexagonal prism 33 with the door frame shell 1. A rotator 6 is left at the corresponding position of the door frame shell 1. The interior of the rotator 6 is an inner hexagonal rotation 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 can also be included for emergency adjustment when the electric control device fails, thereby 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] The 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, the 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 device reaches the upper threshold, the heating ends.

[0074] In this embodiment, a specific structure of a heating anti-icing frame 15 is provided.

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

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

[0077] In this embodiment, a specific implementation method is provided for real-time monitoring of the air pressure difference at both ends of the fixed air intake filter device by using a pressure difference sensor 9.

[0078] In one embodiment, when the pressure drop reaches an alarm state, the control device can be used to select the rotation number and angle of the first side mesh pad 31 and the second side mesh pad 32. When the pressure drop returns to normal, the mesh pad state is selected again according to actual navigation conditions.

[0079] In this embodiment, a specific implementation method is provided under an alarm state. The opening of the first side mesh pad 31 and the second side mesh pad 32 can be adjusted automatically or manually. The pressure difference sensor 19 always monitors the air pressure difference at both ends of the fixed air intake filter device. When the pressure drop reaches the alarm state, the control device 8 can be used to select the rotation number and angle of the first side mesh pad 31 and the second side mesh pad 32. 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 using the above-mentioned adjustable fixed air intake filter device for ships, and the air-water separator of the ship uses the above-mentioned adjustable fixed air intake filter device for ships to filter and clean the air.

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

[0082] Beneficial effects:

[0083] The advantage of the present invention is that a set of air intake mesh pad devices with a rotating function is designed in the fixed filter, which realizes the dynamic control of the wind pressure drop in the air intake duct and achieves the purpose of continuous and stable air intake of the ship under complex conditions. The marine adjustable fixed air intake filter device takes into account the filtering and bypass functions, reduces the number of ship equipment, optimizes the layout of the air intake device, reduces the design of the cabin holes, increases the overall structural strength of the hull, and improves the reliability of the operation of the air intake device under severe cold conditions. The device is equipped with a pressure difference sensor, a pneumatic adjustment device and a control device, which realizes automatic or manual adjustment of the air intake, satisfies the dynamic balance of the air intake flow and pressure drop, and enhances the environmental adaptability of the air intake device.

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

[0085] Door frame shell 1, front inertia stage 2, left first side mesh pad 31 with rotation function, right second side mesh pad 32 with rotation function, rear inertia stage 4, heating and 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 shell 1 through the hexagonal prism 33. The opening and closing execution structure 101 is linked with the pressure difference sensor 9, the pneumatic adjustment device 10 and the control device 8. The rotation direction and amplitude of the execution structure 101 are controlled manually or automatically to achieve the adjustment of the air flow. When the pressure drop of the intake air flow is greater than the preset value, the control device 8 alarms. When the pressure drop is greater than the threshold, the execution structure 101 rotates automatically, and the first side mesh pad 31 and the second side mesh pad 32 are automatically opened. When the pressure drop is lower than the preset value, the second side mesh pad 32 is closed. At this time, the pressure drop value is still lower than the preset value for 5 minutes, and the first side mesh pad 31 is automatically closed. In this process, the opening and rotation angles of the first side mesh pad 31 and the second side mesh pad 32 can be manually controlled.

[0087] The heated anti-icing frame 5 is composed of a temperature sensor 51 and an electric heating wire 52, and is installed between the first side mesh pad 31, the second side mesh pad 32 and the door frame shell 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 be opened and closed freely under severe cold conditions, thereby improving the overall reliability of the equipment.

The protection scope of the present invention is defined by the claims.
