Description

Technical Field

[0001] This invention relates to the field of marine diesel generator sets, and in particular to a marine ultra-quiet diesel generator set. Background Technology

[0002] Marine diesel generator sets are the core equipment of a ship's power system. Their reliable operation is directly related to the ship's navigation safety, operational capabilities, and crew life. A typical marine diesel generator set mainly consists of a diesel internal combustion engine, a generator, and a heat exchanger.

[0003] When ships are sailing at sea, the humidity concentration in and around the ship's cabin is higher than that on land. This moisture-rich environment can affect the air intake of diesel internal combustion engines, as detailed below: When humid air enters the cylinder and participates in combustion, water vapor absorbs some of the heat of compression and combustion, thereby reducing the peak temperature of the combustion chamber in the diesel internal combustion engine. This leads to a series of problems such as prolonged combustion delay period, incomplete combustion process, and increased fuel consumption rate, affecting the unit's economy and power output stability.

The first oil-filled shell contains hydraulic oil, and the first sealing element is provided with a first fan-shaped hole, which is used to guide the flow of hydraulic oil in the adjacent first oil-filled shells.

[0008] More preferably, the sliding frame is fixedly connected to a guide that contacts the inner side of the adjacent fixed tube.

[0009] More preferably, the sliding frame is fixedly connected to a sliding plate, which is used to block the movement trajectory of the sliding frame on the adjacent fixed tube.

[0010] More preferably, a sliding seat is slidably connected to the side of the first oil-containing shell away from the rotating drum, and a spring is fixedly connected between the sliding seat and the adjacent first sealing member. A rotating member is slidably connected to the side of the first oil-containing shell away from the rotating drum and rotatably connected to the adjacent sliding seat. The sliding seat is provided with a second sector-shaped hole, and the rotating member is used to block the second sector-shaped hole on the adjacent sliding seat. The rotating member is provided with a third sector-shaped hole, which is used to communicate with the second sector-shaped hole on the adjacent sliding seat.

[0011] More preferably, the first oil-containing shell is fixedly connected to a fixing frame, the fixing frame is fixedly connected to a pull rope, the pull rope passes through an adjacent fixing frame and is fixedly connected to a sliding block, the sliding block is slidably connected to the adjacent fixing frame, and a spring is provided between the sliding block and the adjacent fixing frame, the sliding block being used to compress the adjacent sliding frame.

[0012] More preferably, the lower first air guide shell is fixedly connected to an elastic rod, and a guide roller is rotatably connected to the side of the elastic rod away from the adjacent first air guide shell. The guide roller is used to contact the adjacent pull rope.

[0015] The present invention has the following advantages: By setting a rotating fixed pipe in the intake path of the diesel internal combustion engine, the fixed pipe alternately goes through two stages: intake air moisture absorption and flue gas drying, so as to supply dry air to the diesel internal combustion engine for combustion, thereby improving the combustion delay period, improving the degree of combustion completeness, and reducing fuel consumption. At the same time, the high-temperature flue gas emitted by the diesel internal combustion engine itself is used as a regenerative heat source to heat and desorb the parts that absorb moisture, thus realizing the utilization of flue gas preheating. As high-temperature gas passes through the filter plate, the airflow vibration caused by sound waves is consumed and attenuated by the friction of the pore wall. This reduces the exhaust noise of the diesel internal combustion engine while achieving dehumidification and regeneration. By changing the distance between adjacent filter plates, it can cope with environments with different humidity levels. In the process of using high-temperature flue gas to heat and dry the filter plates, the distance between each filter plate is actively increased to make the distance between the filter plates greater than the distance under the original filtration conditions. This increases the flow space between adjacent filter plates, promotes the diffusion and discharge of water vapor, and enhances the desorption efficiency. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] This invention addresses the problem of high intake air humidity affecting combustion efficiency in marine diesel generator sets by employing the following methods.

[0020] Example 1

[0021] A marine ultra-quiet diesel generator set, please refer to Figures 1-9 As shown, the device includes a base 1, on which a generator 2 and a diesel internal combustion engine 3 are sequentially fixed and mutually driven. The diesel internal combustion engine 3 is equipped with a heat exchanger 4, an intake pipe 5, and an exhaust pipe 6. A fixed shell 7 is fixed to the base 1, and two first air guide shells 8 are fixed to the fixed shell 7. The intake pipe 5 is fixed to and communicates with the upper first air guide shell 8. A rotating cylinder 9 is rotatably connected to the fixed shell 7. Two second air guide shells 10, both fixed to the fixed shell 7, are rotatably connected inside the rotating cylinder 9. The exhaust pipe 6 is fixed to and communicates with the lower second air guide shell 10. The upper second air guide shell 10 is fixed to and communicates with an air inlet pipe, and the lower first air guide shell 8 is fixed to and communicates with an air outlet pipe. A ring-shaped packing block 11 and a ring-shaped fixed pipe 12 are fixed to the rotating cylinder 9. The ring-shaped packing block 11 and the ring-shaped fixed pipe 12 are staggered. A filter component is provided inside the fixed pipe 12 near the rotating cylinder 9.

[0022] In the above scheme, the heat exchanger 4 is an existing seawater-freshwater heat exchange device. The operating principle of the heat exchanger 4 is as follows: the diesel internal combustion engine 3 is cooled by freshwater, and then the freshwater is cooled by seawater. A single-shaft motor is fixedly connected to the base 1. The motor and the rotating drum 9 are equipped with a pulley belt to transmit power from the single-shaft motor to the rotating drum 9, so that the rotating drum 9 rotates. During the rotation, the connection position between the fixed pipe 12 and the second air guide shell 10 is continuously switched. The air outlet pipe fixedly connected to the first air guide shell 8 on the lower side can be directly connected to the outside. The filling block 11 and the adjacent fixed pipe 12 are fixedly connected. From front to back, all the filling blocks 11 and all the fixed pipes 12 are spliced ​​together to form a complete circle.

[0023] Please refer to Figures 8-11 As shown, the filter component includes several folded support frames 121, all of which are housed within a fixed tube 12. A filter plate 122 is detachably mounted on each support frame 121. Adjacent support frames 121 are hinged together by a connector 123. A limiting plate 124 is fixedly connected within the fixed tube 12. One support frame 121 near the rotating drum 9 is rotatably connected to the limiting plate 124. The limiting plate 124 has a limiting groove for guiding the remaining support frames 121 to slide. A sliding frame 13 is slidably connected within the fixed tube 12, penetrating adjacent fixed tubes 12. The sliding frame 13 is connected to the same fixed tube 12. 2. Any one of the bearing frames 121 except the bearing frame 121 that is rotatably connected to the limiting plate 124 is rotatably connected. The fixed pipe 12 is fixedly connected to the first oil holding shell 14. The first oil holding shell 14 is slidably connected to the first sealing element 15 that is fixedly connected to the adjacent sliding frame 13. The first oil holding shell 14 contains hydraulic oil. The first sealing element 15 is provided with a first fan-shaped hole. The first fan-shaped hole is used to guide the flow of hydraulic oil in the adjacent first oil holding shell 14. The sliding frame 13 is fixedly connected to the guide element 16 that contacts the inner side of the adjacent fixed pipe 12. The sliding frame 13 is fixedly connected to the sliding plate 17. The sliding plate 17 is used to block the movement trajectory of the sliding frame 13 to the adjacent fixed pipe 12.

[0024] In the above scheme, the fixed tube 12 has two symmetrically distributed limiting plates 124, which are used to keep the support frame 121 stable during movement. The filter plate 122 can be an activated alumina ceramic plate (for illustrative purposes only), which has moisture absorption capacity. When high-temperature flue gas passes through the filter plate 122, the airflow vibration caused by sound waves is consumed and attenuated by the friction of the hole wall, thereby achieving the effect of noise reduction. Loose filter cloth can be installed between the two sides of the support frame 121 near the rotating cylinder 9 and the adjacent fixed tube 12 to cover the gap between the support frame 121 near the rotating cylinder 9 and the adjacent fixed tube 12 after rotation. The guide 16 is composed of a support shell and several rollers. The rollers rotate on the support shell and contact the inner side of the adjacent fixed tube 12. During the movement of the sliding frame 13 along the adjacent fixed tube 12, the contact between the rollers in the guide 16 and the inner side of the fixed tube 12 ensures the stability of the sliding frame 13 during movement.

[0025] Please refer to Figure 11 As shown, a sliding seat 18 is slidably connected to the side of the first oil-containing shell 14 away from the rotating cylinder 9. A spring is fixed between the sliding seat 18 and the adjacent first sealing member 15. A rotating member 19 is slidably connected to the side of the first oil-containing shell 14 away from the rotating cylinder 9 and is rotatably connected to the adjacent sliding seat 18. The sliding seat 18 is provided with a second sector-shaped hole. The rotating member 19 is used to block the second sector-shaped hole on the adjacent sliding seat 18. The rotating member 19 is provided with a third sector-shaped hole, which is used to communicate with the second sector-shaped hole on the adjacent sliding seat 18.

[0026] In the above scheme, the rotating member 19 and the sliding seat 18 each have two third sector holes, which are used to ensure the stability of the sliding seat 18 and the rotating member 19 during the movement process. When the rotating member 19 blocks the second sector hole on the sliding seat 18, it restricts the current position of the sliding seat 18.

[0027] Working principle: When using this device to generate electricity, the user starts the single-axis motor on the base 1. The single-axis motor drives the rotating drum 9 to rotate clockwise via a pulley and belt (according to...). Figure 1 (Viewed from front to back) The rotating drum 9 drives all the fixed pipes 12 and their parts to rotate synchronously. Then the user starts the diesel internal combustion engine 3. The outside gas enters the upper second air guide shell 10 through the air inlet pipe connected to it. The gas entering the upper second air guide shell 10 then enters the fixed pipe 12 that rotates to the upper side. When the gas passes through the fixed pipe 12, it passes through all the filter plates 122 in sequence. The filter plates 122 adsorb the moisture in the gas, so that the gas enters the upper first air guide shell 8 in a dry state through the adjacent fixed pipe 12. Then it is guided by the upper first air guide shell 8 to the air inlet pipe 5. Finally, the air inlet pipe 5 sends the dry gas into the diesel internal combustion engine 3 to realize the gas supply in the diesel internal combustion engine 3.

[0028] After the gas enters the diesel internal combustion engine 3, it mixes with the fuel and burns to do work, thereby driving the generator 2 to operate and producing high-temperature flue gas. The high-temperature flue gas after combustion is discharged into the lower second air guide shell 10 through the exhaust pipe 6. The lower second air guide shell 10 sends the high-temperature flue gas into the fixed pipe 12 that rotates to the lower side. The high-temperature flue gas then passes through all the filter plates 122 inside. During this process, the high-temperature flue gas heats and dries the filter plates 122, causing the water adsorbed by the filter plates 122 in the previous working cycle to evaporate and desorb. The water vapor is carried out with the flue gas flow. The flue gas is guided into the lower first air guide shell 8 through the fixed pipe 12 and finally discharged through the exhaust pipe.

[0029] When the ship travels to areas with air humidity exceeding the aforementioned levels, the user can enhance the filtration efficiency of this invention in the following manner, as detailed below: Taking the adjustment of the filtration level of the upper filter plate 122 as an example, the user rotates the rotating part 19 by 90° so that the lower side of the rotating part 19 no longer blocks the second sector-shaped hole on the adjacent sliding seat 18. At this time, the third sector-shaped hole on the lower side of the rotating part 19 is connected with the corresponding second sector-shaped hole on the adjacent sliding seat 18. Then, the user presses the rotating part 19 down. During the downward movement of the rotating part 19, it drives the sliding seat 18 to move synchronously (during this process, the hydraulic oil in the first oil tank 14 passes through the third sector-shaped hole of the rotating part 19 and the second sector-shaped hole of the adjacent sliding seat 18). The sliding seat 18 squeezes the first sealing member 15 through the spring spring, so that the first sealing member 15 moves downward and drives the adjacent sliding frame 13 to move synchronously (the hydraulic oil in the first oil tank 14...). Hydraulic oil passes through the first sector-shaped hole of the first seal 15. During the movement of the sliding frame 13, the sliding plate 17 moves synchronously, thereby blocking the movement trajectory of the sliding frame 13 and preventing air leakage. During the movement of the sliding frame 13, it squeezes the adjacent bearing frame 121 (the upper bearing frame 121 slides down along the limiting groove of the adjacent limiting plate 124). The bearing frame 121 squeezes the lower bearing frame 121 through the adjacent connecting piece 123, and so on, thereby shortening the distance between all the bearing frames 121 in the fixed pipe 12. The distance between the filter plates 122 installed on each bearing frame 121 also decreases synchronously, thereby increasing the number of filter plates 122 that the gas passes through in the unit flow length and increasing the contact time between the moisture and the filter plates 122.

[0030] After the distance between two adjacent filter plates 122 is adjusted, the user stops pressing the rotating part 19 and then twists the rotating part 19 in the opposite direction by 90°. After the rotating part 19 rotates in the opposite direction by 90°, it blocks the second sector hole on the adjacent sliding seat 18, thereby fixing the current position of the first sealing part 15. When further adjustment is needed, the above can be repeated. When power generation is no longer needed, the aforementioned power components can be turned off.

[0031] To ensure the drying efficiency of all filter plates 122 within the same fixed tube 12, the present invention increases the distance between all filter plates 122 within the same fixed tube 12 when heating and drying the filter plates 122, as detailed below.

[0032] Example 2

[0033] Based on Example 1, please refer to Figure 9 and Figures 11-14 As shown, the first oil-containing shell 14 is fixedly connected to a fixed frame 20, and the fixed frame 20 is fixedly connected to a pull rope 21. The pull rope 21 passes through the adjacent fixed frame 20 and is fixedly connected to a sliding block 22. The sliding block 22 is slidably connected to the adjacent fixed frame 20. A spring is provided between the sliding block 22 and the adjacent fixed frame 20. The sliding block 22 is used to squeeze the adjacent sliding frame 13. The lower first air guide shell 8 is fixedly connected to an elastic rod 23. The side of the elastic rod 23 away from the adjacent first air guide shell 8 is rotatably connected to a guide roller 24. The guide roller 24 is used to contact the adjacent pull rope 21.

[0034] In the above scheme, after the pull rope 21 is blocked by the guide roller 24, the pull rope 21 pulls the sliding block 22. When the sliding block 22 moves to contact the adjacent sliding frame 13, the sliding frame 13 moves along with the sliding block 22, so that the sliding frame 13 pulls the adjacent bearing frame 121, providing power for the expansion of all bearing frames 121 in the same fixed tube 12. The elastic coefficient of the elastic rod 23 itself is greater than the elastic coefficient of the spring in the fixed frame 20. The moving stroke of the sliding block 22 on the adjacent fixed frame 20 is greater than the moving stroke of the sliding frame 13 on the adjacent fixed tube 12.

[0035] Please refer to Figure 9 and Figure 12 As shown, a second oil tank 25 is fixedly connected to the side of the fixed pipe 12 away from the adjacent first oil tank 14. The second oil tank 25 is slidably connected to a second sealing element 26 fixedly connected to the adjacent sliding frame 13. The second oil tank 25 contains hydraulic oil. The second sealing element 26 is provided with a first through hole 27 and a second through hole 28. The first through hole 27 and the second through hole 28 are used to guide the flow of hydraulic oil in the adjacent second oil tank 25. A one-way valve is fixedly connected to both the first through hole 27 and the second through hole 28. The one-way valve in the first through hole 27 and the one-way valve in the second through hole 28 have opposite functions. The diameter of the first through hole 27 is larger than the diameter of the second through hole 28.

[0036] In the above scheme, in this invention, there are two first through holes 27 and two second through holes 28, which are arranged in a cross shape to ensure the stability of the second seal 26 during movement. When the second seal 26 moves away from the rotating cylinder 9, the one-way valve in the first through hole 27 is open and the one-way valve in the second through hole 28 is closed. Conversely, when the second seal 26 moves closer to the rotating cylinder 9, the one-way valve in the first through hole 27 is closed and the one-way valve in the second through hole 28 is open. Through the diameter difference between the first through hole 27 and the second through hole 28, the speed at which the second seal 26 moves closer to the rotating cylinder 9 is slower than the speed at which the second seal 26 moves away from the rotating cylinder 9.

[0037] Working principle: Before the filter plate 122 is heated and dried by high-temperature flue gas, the rotating drum 9 drives all the fixed tubes 12 and their parts to rotate clockwise synchronously. When one of the fixed tubes 12 rotates with the rotating drum 9 until the pull rope 21 on it is blocked by the guide roller 24, since the elastic coefficient of the elastic rod 23 is greater than the elastic coefficient of the adjacent spring of the sliding block 22, the guide roller 24 pulls the adjacent pull rope 21 as the fixed tube 12 continues to rotate with the rotating drum 9. At that time, the pull rope 21 drives the sliding block 22 to move away from the rotating drum 9. During the movement of the sliding block 22, the adjacent spring is squeezed.

[0038] When the sliding block 22 moves to contact the adjacent sliding frame 13, the sliding frame 13 drives the adjacent first seal 15 and the adjacent second seal 26 to move synchronously away from the rotating cylinder 9. During the movement of the sliding frame 13, it pulls the adjacent bearing frame 121. The bearing frame 121 is pulled by the adjacent connecting piece 123, and so on, so that all the bearing frames 121 in the same fixed tube 12 expand and increase the distance between two adjacent bearing frames 121. Thus, during the process of using high-temperature flue gas to heat and dry the filter plate 122, the distance between the filter plates 122 is greater than the distance under the original filtration conditions. In this way, by increasing the distance between each filter plate 122, water vapor is less likely to accumulate in a local high-humidity environment, stabilizing the water evaporation pressure and thus accelerating the desorption efficiency.

[0039] As the first seal 15 moves along with the sliding frame 13, it compresses the adjacent spring. At the same time, the hydraulic oil in the first oil tank 14 passes through the first sector hole on the adjacent first seal 15. As the second seal 26 moves along with the sliding frame 13, it causes the one-way valve in the first through hole 27 to open under pressure. The hydraulic oil in the second seal 26 then passes through the first through hole 27. When the sliding frame 13 moves to the limit position in the adjacent fixed tube 12 away from the rotating drum 9, the sliding frame 13 stops moving. At this time, the pull rope 21 is pulled to the limit state by the guide roller 24. As the rotating drum 9 continues to move, the pull rope 21 pulls the guide roller 24. At this time, the force on the elastic rod 23 is less than the above-mentioned tension. The elastic rod 23 then drives the guide roller 24 to swing.

[0040] When the elastic rod 23 deforms to the point that the guide roller 24 disengages from the pull rope 21, the pull rope 21 crosses the guide roller 24, the elastic rod 23 deforms in the opposite direction to reset, and the sliding block 22 is pressed and reset by the adjacent spring. During the process of the sliding block 22 sliding and resetting along the adjacent fixed frame 20, it pulls the pull rope 21 to reset and no longer presses the adjacent sliding frame 13. The sliding frame 13 moves and resets with the help of the adjacent elastic spring of the first seal 15. During the process of the sliding frame 13 moving and resetting, it drives the second seal 26 to move in the opposite direction. During the process of the second seal 26 moving in the opposite direction, the one-way valve in the first through hole 27 is closed and the one-way valve in the second through hole 28 is opened, allowing the hydraulic oil in the second oil tank 25 to pass through the second through hole 28. Under the action of the first through hole 27 having a larger diameter than the second through hole 28, the sliding frame 13 moves and resets slowly, reserving time for the heating and drying process of the filter plate 122 to ensure the heating and drying efficiency of the filter plate 122.

[0041] When the spring adjacent to the first seal 15 is reset, the sliding frame 13, the second seal 26 and the first seal 15 stop moving, and the one-way valve in the second through hole 28 closes.

[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
