Description

Technical Field

[0001] The present invention relates to the technical field of temperature control of a marine methanol supply system, in particular to an energy-saving temperature control device for a cold and hot source system of a marine methanol supply system. Background Art

[0002] The marine methanol supply system is a key component in providing a continuous and stable fuel supply for methanol dual-fuel engines. This system includes a heat and cooling system. Because methanol engines have specific fuel inlet temperature requirements, these systems are required to regulate the temperature of the methanol fuel to ensure proper engine operation. These systems primarily utilize heat exchange equipment to heat or cool the methanol fuel.

[0003] In existing technology, the temperature control device in the cold and hot source system of a marine methanol supply system typically uses a heat exchanger to transfer the methanol fuel to the required temperature of the main engine. During the heat exchange process, the pipes inside the heat exchanger are usually fixed. As the methanol fuel flows through the pipes, the fluid near the pipe wall has a low flow rate, which easily forms a "stagnation layer." With extended operation time, the thickness of the stagnation layer gradually increases, resulting in a decrease in the heat transfer coefficient and the temperature control effect. To achieve the target temperature, more heat exchange medium is consumed, indirectly increasing energy consumption.

[0004] Therefore, we propose an energy-saving temperature regulating device for the cold and heat source system of a marine methanol supply system in order to solve the problems raised in the above background technology. Summary of the Invention

The bottoms of the two second forward and reverse motors are respectively installed on the outer surface of one side of the two sealing doors through auxiliary plates.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, the first forward and reverse motor drives the driving gear and chain to rotate, driving the four driven gears and four rotating rods to rotate together, and further the multiple blocking blocks rotate, so that the two adjacent impact tubes always switch back and forth in a state of one closed and one open, and one open and one closed, that is, a thrust is generated back and forth on both sides of the swinging fins, causing them to swing back and forth, thereby driving the two heat exchange tubes to swing. The periodic centrifugal force and shear force generated by the back and forth swinging of the heat exchange tubes can cause the stagnant layer on the inner wall of the tube to be washed and mixed by the fluid in the mainstream area, thereby enhancing the turbulence intensity, reducing thermal resistance, and improving the heat exchange efficiency between methanol fuel and hot air; at the same time, it disrupts the flow direction of the hot gas, which is conducive to the hot gas wrapping the heat exchange tube more evenly, eliminating the need for additional energy consumption to reach the target temperature, reducing compressed air consumption, and achieving energy-saving optimization.

[0017] 2. When the present invention is used, the heat exchange box is divided into three heat exchange chambers, and each heat exchange chamber corresponds to a vortex tube, which can realize gradient thermal regulation of heat output and independently control the hot air and cold air output ratio of the corresponding vortex tube to avoid energy waste in full-load operation. The three heat exchange chambers and three vortex tubes bear "basic load", "fluctuating load" and "emergency load" respectively. When the marine methanol supply system is in low demand, only one vortex tube can be started to maintain the basic temperature; when it is in medium demand, two vortex tubes are started, and the two heat exchange units are coordinated for adjustment; when it is in high demand, the three heat exchange units are operated at full power. This "step-by-step response" is more in line with the actual heat demand than the "all or nothing" adjustment of a single unit, reduces energy redundancy, realizes energy distribution on demand, and saves energy.

[0018] 3. When the present invention is in use, hot air generates swinging thrust on the oscillating fins while transferring excess heat to the oscillating fins. This heat is then transferred to the fixed tubes and the liquid inlet of the heat exchange tubes, thereby preheating (or precooling) the formaldehyde fuel at the liquid inlet of the heat exchange tubes, reducing energy waste. Excess heat or cold air can be recovered through the energy recovery tubes and used by other equipment on the ship, thereby improving the overall energy utilization rate.

[0019] 4. When the present invention is in use, the second forward and reverse motor drives the rotating shaft to rotate, simultaneously driving the conical limit clamp to rotate. The clamp is clamped on the outside of the heat exchange tube to prevent it from rotating when not needed. The limit assembly can fix the heat exchange tube and use the heat exchange tube in a fixed state. The second forward and reverse motor drives the conical limit clamp to rotate away from the outer surface of the heat exchange tube, allowing the heat exchange tube to be used in a movable state, which is flexible and versatile and improves applicability.

The multiple connecting cavities 219 are connected to the interior of the heat exchange box 202 through the exhaust holes 215. The bottoms of the three vortex tubes 207 are mounted on top of the insulation plate 201 via auxiliary plates.

[0024] In this embodiment, when in use, the air flow control valve 206, the discharge control valve 228, the temperature sensor 229, the feed control valve 230, the first forward and reverse motor 305, the second forward and reverse motor 401 and the PLC controller 1 are electrically connected. Figure 7 As shown, four rows of exhaust holes 215 are provided on the bottom surface of the heat exchange box 202. Under the action of two partitions 214, the interior of the heat exchange box 202 is divided into three heat exchange chambers. The bottom of each heat exchange chamber corresponds to two connecting cavities 219. Each heat exchange chamber corresponds to four rows of exhaust holes 215. Every two adjacent rows of exhaust holes 215 are connected to the connecting cavities 219 at the bottom. Figure 8 As shown, the four connecting chambers 219 on both sides are connected to the exhaust chamber 218 through the eight impact tubes 220 on both sides, and the two connecting chambers 219 in the middle are connected to the two partitions 214 through the eight impact tubes 220 in the middle. The interiors of the two partitions 214 are connected to the exhaust chamber 218, and the exhaust chamber 218 is connected to the exhaust pipe 211. With the insulation plate 201 as the symmetry axis, the two heat exchange boxes 202 are symmetrically arranged, as shown in FIG. Figure 7As shown, they correspond to heating and cooling respectively. A rotary hole is provided at the bottom of the surface of the partition 214, and the heat exchange tube 301 is embedded in the rotary hole. Start the energy-saving heat exchange component 2 to adjust the temperature of the formaldehyde fuel. Taking the heating of the formaldehyde fuel as an example, the hot gas enters the heating heat exchange box 202 to heat the formaldehyde fuel in the heat exchange tube 301, and then the hot gas enters the multiple impact tubes 220 through the connecting cavity 219. There are two impact tubes 220 corresponding to the bottom of each swing fin 303, and the bottom of one of the impact tubes 220 is blocked by the blocking block 310, and the gas cannot enter the impact tube 220. The other impact tube 220 is in a connected state, as shown in FIG. Figure 9As shown, the gas in the connecting chamber 219 is ejected upward through the connected impact tube 220, generating an upward thrust on one side of the swinging fin 303, pushing it upward. This forces the heat exchange tube 301 to rotate about the fixed tube 227, and also causes the center of gravity ball 302 to rotate with it. When the other side of the swinging fin 303 contacts the curved plate 304, the swinging fin 303 and the heat exchange tube 301 cannot continue to rotate. Under the influence of the center of gravity ball 302, the heat exchange tube 301 rotates in the opposite direction and resets. The first forward / reverse motor 305 is pre-activated, driving the driving gear 306 and chain 307. This in turn drives the four driven gears 308 and four rotating rods 309, which in turn rotate the multiple blocking blocks 310. The previously upward-pointing blocking block 310 is rotated to one side. The previously blocked impact tube 220 is now unblocked, and the previously connected impact tube 220 is now blocked. Gas is then ejected upward from the other (unblocked) impact tube 220, generating a thrust force on the other side of the swinging fin 303, causing the heat exchange tube 301 to rotate in the opposite direction (the two heat exchange tubes 301 always swing in the same direction). The limiting action of the curved plate 304 limits the swinging range of the heat exchange tube 301 to within the tapered extension range of the tapered limit clamp 403. The forward and reverse rotation of the first forward and reverse motor 305 causes the rotating rod 309 to rotate back and forth with the blocking block 310, thereby switching the two impact tubes 220 back and forth between a closed and open state, and an open and closed state. This generates a back-and-forth thrust on both sides of the swinging fins 303, causing them to swing back and forth, thereby driving the two heat exchange tubes 301 to swing in the same direction. The periodic centrifugal and shear forces generated by the back-and-forth swinging of the heat exchange tubes 301 disrupt the stable state of the boundary layer, causing the stagnant layer on the inner wall of the tube to be flushed and mixed by the mainstream fluid, thereby increasing the turbulence intensity, reducing thermal resistance, and improving the heat exchange efficiency between the methanol fuel and the hot air. At the same time, the swinging heat exchange tubes 301 disrupt the flow direction of the hot gas, preventing it from forming gas stagnation in dead corners of the heat exchange box 202. This helps the hot gas more evenly wrap around the heat exchange tubes 301, reducing local energy waste, and enabling the energy-saving heat exchange assembly 2 to operate efficiently over a wider range of operating conditions, eliminating the need for additional energy consumption to achieve the target temperature and reducing compressed air consumption. With the cooperation of the energy-saving heat exchange component 2 and the swing component 3, the heat exchange efficiency is improved, energy-saving optimization is realized, and the problem that the pipes inside the temperature control device in the cold and hot source system of the marine methanol supply system are usually fixed, and the fluid close to the pipe wall is prone to form a "stagnant layer" when the methanol fuel flows, and the thickness of the stagnant layer gradually increases with the extension of the operating time, resulting in a decrease in the heat transfer coefficient, a decrease in the temperature control effect, and an indirect increase in energy consumption is solved.

When the formaldehyde fuel needs to be heated, the feed control valves 230 and discharge control valves 228 corresponding to the cooling heat exchanger box 202 are closed. One end of the gas injection main 204 is connected to an external compressed gas injection device. Compressed air flows through the gas injection main 204 into the three gas injection branches 205, which then flow into the three vortex tubes 207, generating high-temperature hot gas and low-temperature cold gas. These gas flows into the hot gas pipe 208 and the cold gas pipe 209, respectively, and then into the outlet pipe 212 through the medium pipe 210. Finally, the hot gas and cold gas are delivered to the three heat exchange chambers within the heating and cooling heat exchanger boxes 202 and 202, respectively, through the outlet nozzles 213. The formaldehyde fuel is transported to the three-way pipe 225 corresponding to the temperature increase through the feed pipe 223, and then enters the heat exchange pipe 301 through the corresponding two fixed pipes 227. The heat exchange pipe 301 is driven to swing back and forth by the swing component 3 and the limit component 4, so that the formaldehyde fuel flows in the heat exchange pipe 301 in a swinging motion state, passes through the three heat exchange chambers in sequence, exchanges heat with the hot air, and increases the temperature of the formaldehyde fuel. Finally, it enters the discharge pipe 224 through the fixed pipe 227 and the three-way pipe 225, and is finally discharged after the temperature increase, thereby regulating 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 a vortex tube 207, which can realize gradient thermal regulation of heat output and independently control the hot air and cold air output ratio of the corresponding vortex tube 207 to avoid energy waste in full-load operation. The three heat exchange chambers and the three vortex tubes 207 bear "basic load", "fluctuating load" and "emergency load" respectively. When the marine methanol supply system is in low demand, only one vortex tube 207 can be started to maintain the basic temperature; when it is in medium demand, two vortex tubes 207 are started, and the two heat exchange units are coordinated and adjusted; when it is in high demand, the three heat exchange units run at full power. This "step response" is more in line with the actual heat demand than the "all or nothing" adjustment of a single unit, reduces energy redundancy, realizes energy distribution on demand, and saves energy. The temperature of the formaldehyde fuel is monitored by the temperature sensor 229, and the detected temperature data is transmitted to the PLC controller 1 in the form of an electrical signal for identification and comparison. According to the temperature conditions, the compressed gas injection amount is controlled by controlling the air flow control valve 206 to avoid energy waste caused by excessive operation of the compressed gas injection equipment.

[0027] Furthermore, the hot air in the heat exchange box 202 enters the corresponding connecting cavity 219 through the exhaust holes 215 at the bottom. It then flows through the impact pipe 220 into the exhaust cavity 218, generating a swinging thrust on the swinging fins 303 while transferring excess heat to them. This heat is then transferred to the fixed tube 207 and the liquid inlet end of 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.

[0028] Furthermore, when the formaldehyde fuel is subjected to temperature regulation, the cooling and heat exchange box 202 is in an idle state, and the energy recovery pipe 216 in the cooling and heat exchange chamber 202 is connected to an external water supply device, so that water flows in the energy recovery pipe 216 and exchanges heat with the cold air in the cooling and heat exchange box 202 to reduce the water temperature, thereby obtaining cold water, which is convenient for cooling other equipment on the ship; similarly, when the formaldehyde fuel is subjected to temperature regulation, the corresponding energy recovery pipe 216 is used to absorb heat to obtain hot water, which is beneficial to improving the comprehensive utilization rate of energy.

[0029] Example 3: Figure 2 and Figure 4-Figure 6 As shown, the limiting assembly 4 includes two second forward and reverse motors 401, and the output ends of the two second forward and reverse motors 401 are fixedly installed with a rotating shaft 402. The outer surfaces of the two rotating shafts 402 are fixedly installed with two conical limiting clamps 403. The outer surfaces of the four heat exchange tubes 301 are respectively movably embedded in the inside of the four conical limiting clamps 403. The outer surfaces of one side of the two heat exchange boxes 202 are respectively installed with sealing doors 203 by bolts. 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 a second sealing ring 226. One end of the two rotating shafts 402 is respectively movably embedded in the outer surfaces of both sides of the insulation plate 201, and 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 installed on the outer surfaces of one side of the two sealing doors 203 through auxiliary plates.

[0030] In this embodiment, when in use, the arc plate 304 and the center of gravity ball 302 cooperate to limit the swing amplitude of the heat exchange tube 301, so that it rotates within the extension range of the conical limiting clamp 403. Start the second forward and reverse motor 401 to drive the rotating shaft 402 to rotate, and at the same time drive the conical limiting clamp 403 to rotate from vertical to horizontal, as shown in FIG. Figure 6As shown. Because the swing range of the heat exchange tube 301 is within the expansion range of the conical limiting clamp 403, even if the heat exchange tube 301 is in a slightly tilted state, when the conical limiting clamp 403 rotates, its expanded inclined surface will contact the heat exchange tube 301, and during the rotation process, its inclined surface will generate a thrust toward the center of the heat exchange tube 301, thereby causing the heat exchange tube 301 to rotate toward the center of gravity of the conical limiting clamp 403, thereby causing the conical limiting clamp 403 to be clamped on the outside of the heat exchange tube 301, thereby limiting the heat exchange tube 301 and preventing it from rotating when not needed. Under the action of the limiting assembly 4, the heat exchange tube 301 can be fixed, and the heat exchange tube 301 in a fixed state can be used; the conical limiting clamp 403 is driven by the second forward and reverse motor 401 to rotate away from the outer surface of the heat exchange tube 301, and the heat exchange tube 301 in an active state can be used, which is flexible and diverse and improves applicability.

[0031] The overall mechanism achieves the following effects and operates 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 exchanger box 202 are closed. Compressed air flows through the main air injection pipe 204 into the three air injection branches 205, then into the three vortex pipes 207, generating high-temperature hot air and low-temperature cold air. These air then enter the hot air pipe 208 and the cold air pipe 209, respectively. The hot air then flows through the medium pipe 210 into the outlet pipe 212, and finally, through the outlet nozzle 213, the hot air and cold air are delivered to the three heat exchange chambers within the heating and cooling heat exchanger boxes 202, respectively. The formaldehyde fuel is delivered through the feed pipe 223 to the corresponding T-tube 225 for heating, then through the corresponding two fixed pipes 227 into the heat exchange tube 301, where it passes through the three heat exchange chambers for gradient temperature adjustment. During discharge, the temperature is monitored by temperature sensor 229 and transmitted to PLC controller 1 for identification and comparison. Based on the temperature, PLC controller 1 controls the amount of compressed gas injected by controlling air flow control valve 206. The hot gas then flows through connecting cavity 219 into multiple impingement tubes 220. Because one impingement tube 220 is blocked while the other is connected, the gas is ejected upward through the connected impingement tube 220, generating an upward thrust on one side of the swinging fin 303. This causes the heat exchange tube 301 to rotate the center of gravity ball 302 about the fixed tube 227. When the other side of the swinging fin 303 contacts the curved plate 304, the swinging fin 303 and heat exchange tube 301 are unable to rotate further. The center of gravity of the center of gravity ball 302 causes the heat exchange tube 301 to rotate in the opposite direction and reset. The first forward and reverse motor 305 is started in advance, driving the driving gear 306 and chain 307 to rotate, which then drives the four driven gears 308 and four rotating rods 309 to rotate together, further driving the multiple blocking blocks 310 to rotate, causing the previously blocked impact tube 220 to lose its blockage and the previously connected impact tube 220 to become blocked. At this time, gas is ejected upward from the other impact tube 220, generating thrust on the other side of the swinging fin 303, causing the heat exchange tube 301 to rotate in the opposite direction. The forward and reverse rotation of the first forward and reverse motor 305 causes the rotating rod 309 to drive the blocking block 310 to rotate back and forth, causing the two impact tubes 220 to switch back and forth between a closed and open state, and an open and closed state. This generates thrust on both sides of the swinging fin 303, causing it to swing back and forth, thereby driving the two heat exchange tubes 301 to swing in the same direction. The hot gas generates a swinging thrust on the swinging fins 303 while transferring waste heat to the swinging fins 303. This heat is then transferred to the fixed tube 207 and the liquid inlet end of the heat exchange tube 301, thereby preheating the formaldehyde fuel at the liquid inlet end of the heat exchange tube 301 before it is discharged through the exhaust pipe 211. The second forward and reverse motor 401 is activated, driving the rotating shaft 402 to rotate, which in turn drives the conical limit clamp 403 from a vertical to a horizontal position, clamping onto the outside of the heat exchange tube 301 to limit the position.

[0032] 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 forward and reverse motor 305, the second forward and reverse motor 401 and the PLC controller 1 are all existing technologies, and their components and usage principles are all public technologies, so no further explanation will be given here.
