Description

Technical Field

[0001] The present invention relates to the technical field of marine piston engines, and specifically relates to a device for bidirectional adaptive regulation of the temperature of marine methanol fuel. Background Art

[0002] In order to achieve the goal of ship emissions reduction, low-carbon fuels are used to replace traditional fuels, such as methanol fuel. In order to ensure that the methanol fuel supply of a methanol fuel engine or a methanol dual-fuel engine meets the requirements of high-quality combustion and energy conversion of the engine, it is necessary to modulate the state parameters of the methanol fuel entering the engine through a methanol fuel supply system, including flow rate, pressure, temperature, etc. However, the current temperature regulation system usually sets a fixed outlet water temperature. When using a dual-fuel engine, different temperatures are required for the working modes of the two fuels, and the regulation speed of the traditional temperature regulation system cannot meet the temperature regulation requirements of the dual-fuel engine.

[0003] For this reason, the Chinese patent with the authorization announcement number CN114856794B discloses a water temperature control method for a marine diesel-methanol dual-fuel engine. When it operates in the diesel mode and the dual-fuel mode, the water temperature is controlled in different modes accordingly. Thus, it avoids the situation of too high exhaust gas temperature of the engine due to insufficient cooling in the diesel mode, and the engine working instability caused by easy flameout in the dual-fuel mode, as well as the safety hazard caused by unburned fuel escaping into the exhaust pipe, improves the engine efficiency and economy, and enhances the reliability of the engine water temperature control.

[0004] However, the traditional temperature regulation system usually judges the outlet temperature through a temperature sensor, and then controls the cooling efficiency by adjusting the flow rate of the coolant. When the temperature of the methanol fuel is lower than the set working temperature, it needs to be heated to stabilize the combustion efficiency of the methanol fuel, but the problem of quickly regulating the methanol fuel cannot be solved only by reducing the cooling efficiency.

Detailed implementation manners

[0034] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation manners.

[0035] Refer to Figures 1-6: A two-way adaptive temperature control device for marine methanol fuel, comprising an exchange box 1, and a heat exchange mechanism 2 is arranged inside the exchange box 1; the heat exchange mechanism 2 includes a heat exchange tube 21 and a three-way pipe 22, liquid inlet pipes 211 and liquid outlet pipes 212 are respectively arranged at two ends of the heat exchange tube 21, the three-way pipe 22 includes a main rod, a first branch pipe 222 and a second branch pipe 223, and the main pipe 221 of the three-way pipe 22 is communicated with the liquid inlet pipe 211; a switching mechanism 3 for controlling the communication between the first branch pipe 222 and the second branch pipe 223 and the liquid inlet pipe 211 is arranged on the three-way pipe 22, and the switching mechanism 3 includes a movable pipe 31 and a linear driving assembly 32; the movable pipe 31 is movably arranged inside the three-way pipe 22, and the outer wall of the movable pipe 31 is in close fit with the inner wall of the three-way pipe 22. A partition 311 is arranged inside the movable pipe 31, and two notches for communicating with the main pipe 221 of the three-way pipe 22 are formed on the movable pipe 31, and the two notches are respectively located on both sides of the partition 311; a connecting seat 312 is arranged on the movable pipe 31, a guiding frame 224 is arranged on the three-way pipe 22, and the connecting seat 312 is in sliding fit with the guiding frame 224, and the linear driving assembly 32 is used for driving the connecting seat 312 to slide along the guiding frame 224.

[0036] In the present invention, the heat medium or the refrigerant is controlled to enter the heat exchange tube 21 through the exchange box 1, the heat exchange mechanism 2 and the switching mechanism 3 to ensure that the outlet temperature of the methanol fuel remains stable and has a low volatility, and the heat of the ship cooling water is used to heat the methanol fuel, and the seawater is used to cool the methanol fuel. Thus, the two-way temperature control function of the methanol fuel in the methanol fuel supply system skid is realized stably and efficiently, and it has the advantages of simple structure, low manufacturing and maintenance costs, etc. The problem that the traditional temperature regulation system cannot meet the temperature control efficiency of the methanol fuel is solved. The first branch pipe 222 and the second branch pipe 223 of the three-way pipe 22 are respectively used for transmitting the heat medium and the refrigerant. The heat medium is preferably the ship cooling water after heat exchange, so as to make full use of the low-quality heat energy of the ship cooling water without preparing an additional heating device. The refrigerant is preferably seawater, and the methanol fuel is cooled by the seawater in the original seawater pipeline system of the ship. A controller for man-machine interaction is arranged on the exchange box 1, and the linear driving assembly 32 is electrically connected with the controller. The part of the heat exchange tube 21 located in the inner cavity of the exchange box 1 is in a spiral shape, so as to increase the contact area between the methanol fuel and the heat exchange tube 21 and improve the heat exchange efficiency.

[0037] When adjusting the temperature of the methanol fuel, the operator drives the movable pipe 31 to move through the linear driving assembly 32, the movable pipe 31 drives the connecting seat 312 to move, and the movement of the connecting seat 312 is guided by the guiding frame 224. Then, the first branch pipe 222 or the second branch pipe 223 is blocked by the partition 311 on the movable pipe 31, so as to switch the input of the refrigerant or the heat medium. And the temperature of the methanol fuel is regulated through the heat exchange tube 21.

[0038] Refer to Figure 2 、Figure 3 and Figure 6 : The linear drive assembly 32 includes a second support 321, a movable block 322, a connecting rod 323, a first elastic member 324, and a first linear drive 325; the second support 321 is disposed on the guiding frame 224 of the three-way pipe 22; the movable block 322 is slidably mounted on the second support 321; two ends of the connecting rod 323 are respectively hinged to the movable block 322 and the connecting seat 312; two ends of the first elastic member 324 are respectively connected to the movable block 322 and the second support 321; the first linear drive 325 is disposed on the guiding frame 224, and the first linear drive 325 is configured to push the connecting seat 312 to move.

[0039] The present invention realizes the function of driving the connecting seat 312 to move through the second support 321, the movable block 322, the connecting rod 323, the first elastic member 324, and the first linear drive 325, and through the cooperation of the connecting rod 323, the movable block 322, and the first elastic member 324, after the first linear drive 325 drives the connecting seat 312 to move, the connecting seat 312 is supported to improve the position stability of the movable pipe 31, and further, the communication condition of the three-way pipe 22 is controlled by the position of the movable pipe 31. A first support 313 is provided on the connecting seat 312, and a riser 3131 is provided on both sides of the first support 313 close to the two first linear drives 325. The first linear drive 325 is preferably a linear cylinder, and the first linear drive 325 is electrically connected to the controller. When the first linear drive 325 is started, it pushes the riser 3131 on the first support 313, and the first support 313 moves under the thrust, and then drives the connecting seat 312 to move through the first support 313. The connecting seat 312 drives the movable pipe 31 to move. And during the movement of the connecting seat 312, the connecting rod 323 is used to push the movable block 322 to move. When the movable block 322 moves in a direction away from the connecting seat 312, the first elastic member 324 contracts. When the connecting seat 312 passes through the second support 321, the movable seat moves in a direction close to the connecting seat 312 under the elastic force of the first elastic member 324, and the movable block 322 pushes the connecting seat 312 to continue to move through the connecting rod 323, thereby completing the control of the position of the connecting seat 312.

[0040] Refer to Figure 2 、 Figure 3 and Figure 7:A flow regulating mechanism 4 is provided on the tee pipe 22. The flow regulating mechanism 4 includes a valve plate 41, a first connecting plate 42, a coarse adjustment assembly 43, and a fine adjustment assembly 44. There are two valve plates 41, and the two valve plates 41 are respectively slidably arranged on the first branch pipe 222 and the second branch pipe 223. A connecting mechanism 5 is provided on the tee pipe 22. The first connecting plate 42 is connected to the valve plate 41 through the connecting mechanism 5, and the connecting mechanism 5 is in transmission connection with the linear drive assembly 32. The coarse adjustment assembly 43 is used to control the lifting of the valve plate 41. The fine adjustment assembly 44 is used to control the lifting of the first connecting plate 42.

[0041] The present invention realizes the function of regulating the flow rates of the refrigerant and the heat medium through the flow regulating mechanism 4 and the connecting mechanism 5. And through the transmission cooperation of the connecting mechanism 5 and the linear drive assembly 32, during the process of the linear drive assembly 32 driving the connecting seat 312 to move, the linear drive assembly 32 controls the connecting mechanism 5 to disconnect the connection, and then quickly controls the valve plate 41 to reset through the coarse adjustment assembly 43, reducing the liquid inlet flow rate, and avoiding the situation that the temperature of the methanol fuel fluctuates violently after the refrigerant and the heat medium are switched. After the coarse adjustment is completed, the position of the first connecting plate 42 and the valve plate 41 is precisely adjusted through the fine adjustment assembly 44. In the working state, when the first linear driver 325 pushes the connecting seat 312 to move, the connecting seat 312 drives the movable block 322 to move through the connecting rod 323 when moving. When the movable block 322 moves in the direction away from the connecting seat 312, the first elastic member 324 contracts. During this process, the movable block 322 controls the connecting mechanism 5 to disconnect the connection between the valve plate 41 and the first connecting plate 42. Then the coarse adjustment assembly 43 drives the valve plate 41 to reset, controlling the liquid inlet flow rate, and avoiding the situation that the large-flow liquid inlet impact causes too large a temperature fluctuation of the methanol fuel when switching the heat exchange type. After the switching is completed, the fine adjustment assembly 44 drives the first connecting plate 42 to move towards the position close to the valve plate 41. When the first connecting plate 42 is docked with the valve plate 41 again, the connecting mechanism 5 connects the first connecting plate 42 and the valve plate 41 again, and then precisely controls the movement of the valve plate 41 through the fine adjustment assembly 44, thereby precisely controlling the liquid inlet flow rate.

[0042] Refer to Figure 3 、 Figure 7 and Figure 8 : The connecting mechanism 5 includes a clamping component 51, a control component 52, and a transmission component 53. The clamping component 51 is arranged on the first connecting plate 42, and the first connecting plate 42 is connected to the valve plate 41 through the clamping component 51. The control component 52 is used to control the connection between the clamping component 51 and the valve plate 41, and the control component 52 is in transmission connection with the linear drive assembly 32 through the transmission component 53.

[0043] The present invention realizes the functions of connecting and disconnecting the control valve plate 41 and the first connecting plate 42 through the clamping component 51, the control component 52 and the transmission component 53. In the initial state, the clamping component 51 on the first connecting plate 42 is connected to the valve plate 41. At this time, the first connecting plate 42 and the two valve plates 41 are controlled to move synchronously through the fine adjustment component 44. When switching the control mode, the connecting seat 312 is driven to move by the linear driving component 32. During this process, the linear driving component 32 drives the control component 52 through the transmission component 53, and the control component 52 disconnects the connection of the clamping component 51, and the first connecting plate 42 is separated from the valve plate 41. Then, the valve plate 41 is quickly controlled to move through the coarse adjustment component 43. Then, the first connecting plate 42 is controlled to move towards the valve plate 41 through the fine adjustment component 44 until the valve plate 41 and the first connecting plate 42 are connected again. At this time, the coarse adjustment component 43 is reset, and then the position of the valve plate 41 is precisely adjusted through the fine adjustment component 44.

[0044] Refer to Figure 3 , Figure 8 and Figure 9 : The coarse adjustment component 43 includes an extension frame 431, a second elastic member 432, a second linear driver 433 and a push plate 434; the extension frame 431 is connected to the valve plate 41; a fixed seat 225 is provided on the three-way pipe 22, and both ends of the second elastic member 432 are respectively connected to the extension frame 431 and the fixed seat 225; the second linear driver 433 is arranged on the fixed seat 225, the push plate 434 is in transmission connection with the driving end of the second linear driver 433, and the extension frame 431 is located between the push plate 434 and the second linear driver 433.

[0045] The present invention realizes the function of quickly controlling the movement of the valve plate 41 through the extension frame 431, the second elastic member 432, the second linear driver 433 and the push plate 434. The second linear driver 433 is preferably a linear cylinder, and the second linear driver 433 is electrically connected to the controller. When the operator drives the connecting seat 312 to move through the linear driving component 32 and switches the temperature control mode, the movable block 322 moves upward. And when the connecting rod 323 is in the vertical state, the movable block 322 moves to the upper end of the stroke, and the movable block 322 provides a squeezing force, and this squeezing force is transmitted to the control component 52 through the transmission component 53, and the control component 52 disconnects the connection of the clamping component 51. Then the controller sends a signal to the second linear driver 433, and the second linear driver 433 drives the push plate 434 to move downward. After the push plate 434 contacts the extension frame 431, it pushes the extension frame 431, and the extension frame 431 drives the valve plate 41 to move downward, thereby controlling the valve plate 41 to reset.

[0046] Refer to Figure 3 , Figure 7 and Figure 8:The fine-tuning component 44 includes a bracket 441, a rotary driver 442, a screw 443, and a guide rod 444; the bracket 441 is disposed on the tee pipe 22, and the rotary driver 442 is mounted on the bracket 441; the screw 443 is rotatably disposed on the bracket 441, the screw 443 is threadedly connected to the first connecting plate 42, and the rotary driver 442 is used to drive the screw 443 to rotate; the guide rod 444 is disposed on the bracket 441, and the guide rod 444 is slidably engaged with the first connecting plate 42.

[0047] The present invention realizes the function of controlling the movement of the first connecting plate 42 through the bracket 441, the rotary driver 442, the screw 443, and the guide rod 444. The rotary driver 442 is preferably a servo motor, and the rotary driver 442 is electrically connected to the controller. The driving end of the rotary driver 442 and the screw 443 are both sleeved with bevel gears 445, and the two bevel gears 445 are meshed and connected. In the working state, when the movable seat does not move and the valve plate 41 and the first connecting plate 42 are connected by the clamping component 51. The controller sends a signal to the rotary driver 442, and the rotary driver 442 drives the screw 443 to rotate through the transmission of the two bevel gears 445. The screw 443 drives the first connecting plate 42 threadedly connected thereto to move, and the first connecting plate 42 drives the valve plate 41 to move. And through the deceleration transmission mechanism of the screw 443, the accuracy of the movement of the first connecting plate 42 is improved, and thus the liquid inlet flow rate is accurately adjusted.

[0048] Refer to Figure 8 、 Figures 10-12 :The clamping component 51 includes a second connecting plate 511 and a first clamping block 512; both ends of the second connecting plate 511 are respectively connected to the two valve plates 41; a third support 421 is provided on the first connecting plate 42, the first clamping block 512 is slidably mounted on the third support 421, a third elastic member 5121 is provided on the first clamping block 512, and both ends of the third elastic member 5121 are respectively connected to the first clamping block 512 and the third support 421; a clamping groove 5111 matching with the first clamping block 512 is formed on the second connecting plate 511.

[0049] The present invention realizes the function of connecting the valve plate 41 and the first connecting plate 42 through the third support 421, the second connecting plate 511, and the first clamping block 512. The first clamping block 512 is provided with an inclined surface; when the first clamping block 512 is plugged into the clamping groove 5111, the first connecting plate 42 and the second connecting plate 511 are connected, and the extension frame 431 is provided with a second elastic member 432, and the elastic force provided by the second elastic member 432 can apply thrust to the extension frame 431 and the valve plate 41. When the rotary driver 442 drives the screw 443 to rotate, thereby controlling the first connecting plate 42 to move upward, the valve plate 41 and the extension frame 431 will also move synchronously under the elastic force of the second elastic member 432. When the fine adjustment component 44 drives the first connecting plate 42 to move downward, the first connecting plate 42 pushes the extension frame 431 to move downward. When switching the temperature control mode, the linear drive assembly 32 drives the control assembly 52 through the transmission assembly 53, and the control assembly 52 controls the first clamping block 512 to move, so that the first clamping block 512 is separated from the card slot 5111. Then the valve plate 41 is quickly controlled to move through the coarse adjustment assembly 43. After the switching and adjustment are completed, the first connecting plate 42 is controlled to move downward through the fine adjustment assembly 44. When the first connecting plate 42 abuts against the extension frame 431, the first clamping block 512 on the third support 421 contacts the second connecting plate 511, and the inclined surface on the first clamping block 512 is squeezed, thereby pushing the first clamping block 512 to contract through the squeezing force until the first clamping block 512 is aligned with the card slot 5111, and the first clamping block 512 is clamped with the card slot 5111 under the elastic force of the third elastic member 5121.

[0050] Reference Figure 8 , Figure 10 and Figure 11 : The control component 52 includes a mounting bar 521, a movable bar 522, a fourth support 523 and a fourth elastic member 524; the mounting bar 521 is connected to the three-way pipe 22, and the second connecting plate 511 is slidably matched with the mounting bar 521; the movable bar 522 is movably arranged on the mounting bar 521, the first clamping block 512 is slidably matched with the movable bar 522, and the movable bar 522 is transmission-connected with the transmission component 53; the fourth support 523 is arranged on the mounting bar 521; the two ends of the fourth elastic member 524 are respectively connected to the movable bar 522 and the fourth support 523.

[0051] The present invention realizes the function of controlling the movement of the first clamping block 512 through the installation bar 521, the movable bar 522, the fourth support 523 and the fourth elastic member 524. In the working state, when the linear drive assembly 32 drives the connecting seat 312 to move, the linear drive assembly 32 drives the movable bar 522 to move through the transmission assembly 53, and the movable bar 522 pushes the first clamping block 512, thereby separating the first clamping block 512 from the clamping slot 5111.

[0052] Reference Figure 8 andFigure 13 : The transmission component 53 includes a second clamping block 531 and a fifth elastic member 532; the second clamping block 531 is slidably mounted on the second support 321, and a convex block 5311 that abuts against the movable bar 522 is provided on the second clamping block 531; two ends of the fifth elastic member 532 are respectively connected to the second clamping block 531 and the second support 321.

[0053] The present invention realizes the function of pushing the movable bar 522 to move through the movement of the movable block 322 by means of the second clamping block 531 and the fifth elastic member 532, and further controls the movement of the first clamping block 512. When the movable block 322 moves upward to the uppermost end under the push of the connecting rod 323, the movable block 322 presses the second clamping block 531, the second clamping block 531 is pushed under the action of the pressing force, the convex block 5311 on the second clamping block 531 pushes the movable bar 522, the movable bar 522 moves under the action of the thrust force, and the fourth elastic member 524 elongates under the action of the torque.

[0054] Refer to Figure 1 and Figure 2 : Feed pipes 11 and discharge pipes 12 are respectively arranged at two ends of the exchange box 1; a temperature sensor 121 for sensing the temperature of the discharged liquid is arranged on the discharge pipe 12.

[0055] The present invention realizes the function of sensing the temperature of the discharged liquid through the feed pipe 11 and the discharge pipe 12, and further realizes the function of automatically switching the temperature control mode according to the temperature of the discharged liquid. The temperature sensor 121 is electrically connected to the controller. In order to ensure that the temperature of the methanol fuel is within the specified range, a temperature sensor 121 for sensing the temperature of the discharged liquid is arranged on the discharge pipe 12 of the exchange box 1, the temperature sensor 121 feeds back a signal to the controller, and the controller switches the temperature control mode according to the temperature value to stabilize the temperature of the methanol fuel.
