Description

TECHNICAL FIELD

[0002] The marine methanol supply system is a key equipment for providing continuous and stable fuel supply for a methanol dual-fuel engine. The cold and heat source system is included in the marine methanol supply system. Because the methanol engine has specific requirements for the inlet temperature of the fuel, the cold and heat source system is needed to adjust the temperature of the methanol fuel to ensure the normal operation of the engine. The cold and heat source system of the marine methanol supply system mainly realizes heating or cooling of the methanol fuel through a heat exchange device.

[0003] In the prior art, the temperature adjustment device in the cold and heat source system of the marine methanol supply system usually adopts a heat exchanger to heat the methanol fuel to the required temperature of the main engine. In the heat exchange process, the pipeline inside the heat exchanger is usually fixed. When the methanol fuel flows inside the pipeline, the fluid close to the pipe wall is prone to form a "stagnant layer" due to low flow rate. With the extension of the running time, the thickness of the stagnant layer gradually increases, resulting in a decrease in the heat exchange coefficient and a decrease in the temperature adjustment effect. More heat exchange medium needs to be consumed to reach the target temperature, indirectly increasing the energy consumption.

[0018] Compared with the prior art, the application has the following beneficial effects:

[0019] 1、When the application is used, the first reversible motor drives the driving gear and the chain to rotate, drives the four driven gears and the four rotating rods to rotate, further drives the plurality of blocking blocks to rotate, so that the adjacent two impact pipes are always switched between one blocking and one opening and one opening and one blocking, that is, the two sides of the swing fin are pushed back and forth to swing back and forth, so as to drive the two heat exchange pipes to swing.

Figure 7As shown, respectively corresponding to temperature rise and temperature drop. The surface of the partition 214 is provided with a hole, the movable heat exchange tube 301 is embedded in the hole. Start energy-saving heat exchange assembly 2 for formaldehyde fuel temperature control, for example, formaldehyde fuel temperature rise, hot gas into the heating heat exchange tank 202, the formaldehyde fuel in the heat exchange tube 301 is heated, then the hot gas through the connecting cavity 219 into a plurality of impact pipe 220. Each swing fin 303 below the corresponding two impact pipe 220, and one of the impact pipe 220 is blocked by the bottom of the block 310, the gas can not enter the impact pipe 220, another impact pipe 220 is in communication, such as Figure 9The gas in the connecting cavity 219 is sprayed upward through the communicating impact tube 220, which generates an upward thrust on one side of the swing fin 303, pushes the one side of the swing fin 303 upward, drives the heat exchange pipe 301 to rotate to one side with the fixed pipe 227 as the axis, and drives the gravity center ball 302 to rotate together. When the other side of the swing fin 303 touches the arc-shaped plate 304, the swing fin 303 and the heat exchange pipe 301 cannot continue to rotate, and under the action of the gravity center of the gravity center ball 302, the heat exchange pipe 301 is driven to reverse and reset. The first forward-reverse motor 305 is started in advance, which drives the driving gear 306 and the chain 307 to rotate, and then drives the four driven gears 308 and the four rotating rods 309 to rotate together, and further drives a plurality of blocking blocks 310 to rotate, which rotates the originally upward blocking block 310 to one side, and the originally one-side blocking block 310 is rotated to be upward, so that the originally blocked impact tube 220 is unblocked, and the originally communicating impact tube 220 is blocked.

The periodic centrifugal force and shear force generated by the back-and-forth swinging of the heat exchange pipe 301 can break the stable state of the boundary layer, so that the stagnation layer on the inner wall of the pipe is washed and mixed by the fluid in the main flow area, the turbulent flow intensity is enhanced, the thermal resistance is reduced, and the heat exchange efficiency of the methanol fuel and the hot air is improved; at the same time, the swinging heat exchange pipe 301 can disrupt the flow direction of the hot air, avoid the formation of gas stagnation in the dead angle position in the heat exchange box 202, and be beneficial to the hot air to more evenly wrap the heat exchange pipe 301, reduce local energy waste, so that the energy-saving heat exchange assembly 2 can operate efficiently in a wider working condition range, without additional energy consumption to reach the target temperature, and reduce the consumption of compressed air. Under the cooperation of the energy-saving heat exchange assembly 2 and the swing assembly 3, the heat exchange efficiency is improved, the energy is saved, the problem of the pipe in the temperature regulating device in the cold and heat source system of the methanol supply system of the ship is usually fixed, the fluid close to the pipe wall when the methanol fuel flows is easy to form a "stagnation layer", and with the extension of the running time, the thickness of the stagnation layer gradually increases, thereby causing the heat exchange coefficient to decrease, the temperature regulating effect to decrease, and the energy consumption to increase indirectly.

[0043] In this embodiment, in use, two feed control valves 230 correspond to two three-way pipes 225 respectively, control the formaldehyde fuel into the heating heat exchange box 202 or the cooling heat exchange box 202, and two discharge control valves 228 correspond to the formaldehyde fuel after heating or cooling. When the formaldehyde fuel needs to be heated, the feed control valve 230 and the discharge control valve 228 corresponding to the cooling heat exchange box 202 are closed. One end of the air injection main pipe 204 is connected with an external compressed gas injection device, and the compressed air enters the three air injection branch pipes 205 through the air injection main pipe 204, and then enters the three vortex pipe fittings 207, generating high-temperature hot air and low-temperature cold air, which respectively enter the hot air pipe 208 and the cold air pipe 209, and then enter the air outlet pipe 212 through the medium pipe 210, and finally the hot air and the cold air are respectively transported to the three heat exchange chambers in the heating heat exchange box 202 and the cooling heat exchange box 202 through the air outlet nozzle 213. The formaldehyde fuel is transported to the corresponding three-way pipe 225 through the feed pipe 223, and then enters the heat exchange pipe 301 through the corresponding two fixed pipes 227, and the heat exchange pipe 301 is driven to swing back and forth by the swing assembly 3 and the limiting assembly 4, so that the formaldehyde fuel flows in the heat exchange pipe 301 in a swinging motion state, and sequentially passes through the three heat exchange chambers to exchange heat with the hot air, thereby increasing the temperature of the formaldehyde fuel, and finally the formaldehyde fuel after heating is discharged from the fixed pipe 227 and the three-way pipe 225, so as to adjust the temperature of the formaldehyde fuel. The heat exchange box 202 is divided into three heat exchange chambers, and each heat exchange chamber corresponds to one vortex pipe fitting 207, so as to realize gradient heat regulation and heat output, independently control the output proportion of hot air and cold air of the corresponding vortex pipe fitting 207, avoid energy waste in full-load operation, and realize energy on-demand distribution and energy saving. The three heat exchange chambers and the three vortex pipe fittings 207 bear the “basic load”, “fluctuating load” and “emergency load”, when the marine methanol supply system is in low demand, only one vortex pipe fitting 207 can be started to maintain the basic temperature; when it is in medium demand, two vortex pipe fittings 207 are started, and two heat exchange units are cooperatively adjusted; when it is in high demand, three heat exchange units are operated at full power, so that the “step-by-step response” is more suitable for actual heat demand than the “all or none” adjustment of a single unit, reduces energy redundancy, realizes energy on-demand distribution, and saves energy. The temperature sensor 229 monitors the temperature of the formaldehyde fuel, and transmits the detected temperature data to the PLC controller 1 in the form of electrical signal for identification and comparison, and controls the injection amount of compressed gas by controlling the air flow control valve 206 according to the temperature condition, so as to avoid energy waste caused by excessive operation of the compressed gas injection device.

[0044] Furthermore, the hot gas in the heat exchange box 202 enters the corresponding connecting cavity 219 through the exhaust port 215 at the bottom, and then flows into the exhaust cavity 218 through the impact pipe 220. While generating an oscillating thrust on the oscillating fins 303, it also transfers residual heat to the oscillating fins 303. The heat is then transferred to the liquid inlet end of the fixed pipe 207 and the heat exchange tube 301, thereby preheating (or precooling) the formaldehyde fuel at the liquid inlet end of the heat exchange tube 301 and reducing energy waste. Finally, the gas in the exhaust cavity 218 is discharged through the exhaust pipe 211.

[0045] Furthermore, when the formaldehyde fuel is being heated, the cooling heat exchange box 202 is idle. The energy recovery pipe 216 in the cooling heat exchange box 202 is connected to an external water supply device, allowing water to flow in the energy recovery pipe 216 and exchange heat with the cold air in the cooling heat exchange box 202, thus lowering the water temperature and obtaining cold water, which is convenient for cooling other equipment on the ship. Similarly, when the formaldehyde fuel is being cooled, the corresponding energy recovery pipe 216 is used to absorb heat and obtain hot water, which helps to improve the overall energy utilization rate.

[0046] Example 3: Figure 2 and Figures 4-6 As shown, the limiting assembly 4 includes two second forward and reverse motors 401. The output ends of the two second forward and reverse motors 401 are fixedly mounted with rotating shafts 402. The outer surfaces of the two rotating shafts 402 are fixedly mounted with two conical limiting clamps 403. The outer surfaces of the four heat exchange tubes 301 are respectively movably embedded inside the four conical limiting clamps 403. The outer surfaces of one side of the two heat exchange boxes 202 are each bolted with a sealing door 203. The outer surfaces of one side of the two sealing doors 203 are each provided with a second sealing hole 231. The inner walls of the two second sealing holes 231 are fixedly connected with second sealing rings 226. One end of the two rotating shafts 402 is respectively movably embedded on the outer surfaces of both sides of the insulation plate 201. The outer surfaces of the other ends of the two rotating shafts 402 are respectively in contact with the inner walls of the two second sealing rings 226. The bottoms of the two second forward and reverse motors 401 are respectively mounted on the outer surfaces of one side of the two sealing doors 203 through auxiliary plates.

[0047] In this embodiment, during use, the arc-shaped plate 304 and the center-of-gravity ball 302 restrict the swing amplitude of the heat exchange tube 301, allowing it to rotate within the extended range of the conical limiting clamp 403. Starting the second forward / reverse motor 401 drives the rotating shaft 402 to rotate, simultaneously driving the conical limiting clamp 403 to rotate, from vertical to horizontal, as shown... Figure 6As shown. Because the swing range of the heat exchange pipe 301 is within the expansion range of the conical limiting clamp 403, even if the heat exchange pipe 301 is in a slight inclination state, when the conical limiting clamp 403 rotates, its expanded inclined surface will contact the heat exchange pipe 301, and during the rotation process, the inclined surface will generate a pushing force to the middle of the heat exchange pipe 301, so that the heat exchange pipe 301 rotates to the center of gravity position of the conical limiting clamp 403, and then the conical limiting clamp 403 is clamped on the outside of the heat exchange pipe 301, thereby limiting the heat exchange pipe 301, avoiding its rotation at the time when it is not needed. Under the action of the limiting assembly 4, the fixation of the heat exchange pipe 301 can be realized, and the heat exchange pipe 301 in the fixed state is used; by driving the conical limiting clamp 403 to rotate away from the outer surface of the heat exchange pipe 301 through the second forward and reverse motor 401, the heat exchange pipe 301 in the active state can be used, which is flexible and diverse, and the applicability is improved.

[0048] The effect and working principle of the whole mechanism are as follows: when the formaldehyde fuel needs to be heated, the corresponding feed control valve 230 and discharge control valve 228 of the cooling heat exchange box 202 are closed. The compressed air enters the three air injection branch pipes 205 through the air injection main pipe 204, and then enters the three vortex pipe fittings 207 to generate high-temperature hot gas and low-temperature cold gas, which enter the hot gas pipe 208 and the cold gas pipe 209 respectively, and then enter the gas outlet pipe 212 through the medium pipe 210, and finally the hot gas and the cold gas are respectively delivered to the three heat exchange chambers in the heating heat exchange box 202 and the cooling heat exchange box 202. The formaldehyde fuel is delivered to the corresponding three-way pipe 225 of the heating through the feed pipe 223, and then enters the heat exchange pipe 301 through the corresponding two fixed pipes 227, and then is gradiently tempered in the three heat exchange chambers in turn. When discharging, the temperature is monitored by the temperature sensor 229, and the temperature data is delivered to the PLC controller 1 for identification and comparison, and the PLC controller 1 controls the air flow control valve 206 to control the injection amount of compressed gas according to the temperature. Then the hot gas enters the multiple impact pipes 220 through the connecting cavity 219. Since one of the impact pipes 220 is blocked and the other is connected, the gas is sprayed upward through the connected impact pipe 220, generating an upward thrust on one side of the swing fin 303, so that the heat exchange pipe 301 drives the center of gravity ball 302 to rotate to one side with the fixed pipe 227 as the axis. When the other side of the swing fin 303 touches the arc plate 304, the swing fin 303 and the heat exchange pipe 301 cannot continue to rotate, and under the action of the center of gravity of the center of gravity ball 302, the heat exchange pipe 301 is driven to rotate reversely and reset. The first forward and reverse motor 305 is started in advance, driving the driving gear 306 and the chain 307 to rotate, and then driving the four driven gears 308 and the four rotating rods 309 to rotate together, further driving the multiple blocking blocks 310 to rotate, so that the originally blocked impact pipe 220 loses the blockage, and the originally connected impact pipe 220 is blocked. At this time, the gas is sprayed upward from the other impact pipe 220, and generates a thrust on the other side of the swing fin 303, so that the heat exchange pipe 301 reversely rotates. Through the forward and reverse rotation of the first forward and reverse motor 305, the rotating rod 309 drives the blocking block 310 to rotate back and forth, so that the two impact pipes 220 are switched back and forth in a state of one block and one connection, that is, the two sides of the swing fin 303 are pushed back and forth, so that the swing fin 303 swings back and forth, thereby driving the two heat exchange pipes 301 to swing in the same direction. While the hot gas generates a swing thrust on the swing fin 303, the swing fin 303 will transfer the residual heat to the swing fin 303, and then transfer the heat to the fixed pipe 207 and the liquid inlet end of the heat exchange pipe 301, so as to preheat the formaldehyde fuel at the liquid inlet end of the heat exchange pipe 301, and finally discharge through the exhaust pipe 211. The second forward and reverse motor 401 is started, driving the rotating shaft 402 to rotate, and at the same time driving the conical limiting clamp 403 to rotate from vertical to horizontal, clamping on the outside of the heat exchange pipe 301 to limit.

[0049] Among them, the air flow control valve 206, the vortex tube 207, the discharge control valve 228, the temperature sensor 229, the feed control valve 230, the first positive and negative motor 305, the second positive and negative motor 401 and the PLC controller 1 are all prior art, and their components and use principles are disclosed technologies, which will not be explained in detail here.
