Description

Technical Field

[0001] The invention relates to the technical field of fuel generators, in particular to a container-type methanol fuel generator. Background Art

[0002] With the rapid development of electric vehicles, the charging problem of electric vehicles has become more and more serious. A large number of commercial customers are facing a variety of charging problems such as no charging piles, the inability of the power grid to distribute electricity or insufficient power distribution quota. For passenger cars, as the amount of on-board batteries becomes larger and larger, problems such as difficult charging, slow charging, and insufficient charging piles are also becoming more serious. In addition, the mobility of vehicles is very large, and the charging demand is showing tidal and mobile characteristics.

[0003] For example, a silent container-type methanol self-generating charging device provided by announcement number CN219927481U includes a box-type container, a methanol generator set, a smoke exhaust silencer, an energy storage battery pack, and a methanol fuel tank. The box-type container is provided with a cabin room, a charging equipment room, and an exhaust room. The methanol generator set is arranged in the cabin room. The exhaust port of the methanol generator set is connected to the inlet of the smoke exhaust silencer. The air outlet of the heat dissipation component of the methanol generator set is connected to the exhaust room. The box-type container is provided with a labyrinth air inlet duct, and the exhaust room is provided with an exhaust silencer window. The exhaust room, the cabin room, and the charging equipment room are arranged in sequence from front to back in the box-type container. An integrated charging system is also provided in the charging equipment room. The utility model adopts a methanol generator assembly to ensure high fuel safety, simple fuel supply, simple power generation mechanism, low cost, high reliability, and high efficiency. The labyrinth air inlet duct, smoke exhaust silencer, and exhaust silencer window are used to effectively reduce equipment noise.

[0004] However, when the above technology is actually used, pure methanol is directly used as fuel, which makes cold start difficult. A few existing technologies use gasoline for cold start and then switch to methanol fuel.

The first connecting pipe 514 and the second connecting pipe 516 are connected to the inner part of the circulation channel 513 respectively. The first connecting pipe 514 is fixedly penetrated and extended to the inner part of the inner pipe 505, and the end of the first connecting pipe 514 away from the heat exchange pipe 509 is fixedly installed with an engine cooling liquid inlet pipe 515, the interior of the engine cooling liquid inlet pipe 515 is connected to the interior of the first connecting pipe 514, the engine cooling liquid inlet pipe 515 is fixedly penetrated and extended to one end of the second end ring 508, the end of the second connecting pipe 516 away from the heat exchange pipe 509 is fixedly installed with an engine cooling liquid outlet pipe 517, and the engine cooling liquid outlet pipe 517 is fixedly installed at the second end ring 508 away from the first filter. At one end of the core 507, the engine cooling liquid inlet pipe 515 is fixedly penetrated and extended to the outside of the engine cooling liquid outlet pipe 517, the surface of the engine cooling liquid outlet pipe 517 is fixedly installed with an end cover 518, and the end cover 518 is threadedly connected to the inner wall of the filter tank 502, and the first end ring 506 is fixedly installed with a retaining ring 519 at one end away from the first filter element 507, and the retaining ring 519 is tightly fitted to the inner wall of one end of the filter tank 502, the connecting cover 504 and the first end ring 506 are circular structures, a threaded hole is provided in the middle of the connecting cover 504, and a through hole is provided in the middle of the first end ring 506, and a plurality of through grooves are provided on the side wall of the retaining ring 519, so that the fuel entering the inside of the filter tank 502 through the second pipeline 6 and the first through hole 503,Enter the position between the first filter element 507 and the filter tank 502 through the through groove of the retaining ring 519;

[0045] When the above structure is in use, the methanol inside the second pipe 6 enters the position between the filter tank 502 and the first filter element 507 through the first through hole 503, and the methanol penetrates the first filter element 507 to filter large particles of impurities, and at the same time, the methanol is dispersed and evenly penetrates the first filter element 507. After the methanol penetrates the first filter element 507, it enters the inner wall of the heat exchange tube 509 through the second through hole 510 in the middle of the heat exchange tube 509, and penetrates the second filter element 512 again. At this time, the second filter element 512 finely filters the methanol, and the filtered methanol passes through the second through hole 510 in the middle of the inner tube 505. It enters the inner tube 505, and finally flows to the first pipeline 4 and flows out to the methanol oil rail 3. Since the coolant that absorbs heat circulates in the circulation channel 513, the first connecting pipe 514, the engine cooling liquid inlet pipe 515, the second connecting pipe 516 and the engine cooling liquid outlet pipe 517, the methanol is heated during the process of passing through the second filter element 512 of the heat exchange tube 509 and the inner tube 505, so that the methanol can quickly reach the working temperature. After that, the heated methanol is directly sprayed into the cylinder of the methanol fuel generator 2 to complete the switching between gasoline and methanol.

[0046] Working principle: When in use, the invention sets two sets of methanol fuel generators 2 with parallel output. Compared with large generators, the invention improves the power generation efficiency while reducing the volume, so that the device can be conveniently moved with the action mechanism. When cold starting, the second drive pump 18 first pumps the gasoline in the gasoline tank 24 into the sixth pipeline 17 through the first gasoline inlet pipe 19, and filters the gasoline through the gasoline fine filter 16, and then enters the gasoline rail 13 through the fifth pipeline 15, and finally sprays it into the cylinder of the methanol fuel generator 2 through the gasoline injector 14, so that the methanol fuel generator 2 can work normally. When the second drive pump 18 is working, the second three-way valve 10 cuts off the gasoline. The fourth pipeline 11 is connected to the methanol oil inlet pipe 12, and the fourth pipeline 11 is connected to the third pipeline 9. At the same time, the first driving pump 8 pumps the methanol in the third pipeline 9 into the second pipeline 6 through the fourth pipeline 11, and finally enters the methanol fuel rail 3 through the first pipeline 4 after filtering and heating by the fuel processing assembly, so that the methanol is finally circulated in the methanol fuel rail 3, the third pipeline 9, the fourth pipeline 11, the first driving pump 8, the second pipeline 6, the fuel processing assembly and the first pipeline 4. Under the action of the fuel processing assembly heating the methanol, the heated methanol can be evenly filled in the methanol fuel rail 3, the first pipeline 4 and the second pipeline 6, so as to prevent the following three situations from occurring:

[0047] 1. It can avoid waiting for a long time. In the prior art, it is necessary to wait until the engine temperature heats the methanol in the methanol rail 3, the first pipeline 4 and the second pipeline 6 to the target temperature before switching between gasoline and methanol;

[0048] 2. It can avoid the use of additional heating equipment. Some existing technologies use electric heating and other methods to heat the working temperature of methanol first;

[0049] 3. Avoid unstable operation of the engine during switching. Since the methanol temperatures in the methanol rail 3, the first pipe 4 and the second pipe 6 are inconsistent, the colder methanol will cause differences in ignition performance, which may lead to unstable combustion during injection into the cylinder, resulting in detonation, partial combustion or misfire.

[0050] When the temperature of methanol in the methanol rail 3, the first pipeline 4 and the second pipeline 6 rises to the working temperature, that is, when switching between gasoline and methanol, the second drive pump 18 stops working, and the second three-way valve 10 cuts off the communication relationship between the fourth pipeline 11 and the third pipeline 9, and makes the fourth pipeline 11 connected with the methanol oil inlet pipe 12. At this time, the first drive pump 8 passes the methanol in the methanol tank 23 through the fourth pipeline 11 and the methanol oil inlet pipe 12 through the second pipeline 6, and after filtering and heating by the fuel processing assembly, it is finally sent to the interior of the methanol rail 3 through the first pipeline 4, and sprayed from the methanol injector 7 into the cylinder of the methanol fuel generator 2, so that the methanol fuel generator 2 works normally;

[0051] And when the fuel processing assembly is working, when the methanol fuel generator 2 is cold started by gasoline, the radiator 25 works synchronously, and the radiator 25 pumps the coolant that absorbs the heat of the methanol fuel generator 2 into the engine cooling inlet pipe 515 and the engine cooling outlet pipe 517 for internal circulation. At the same time, the methanol inside the second pipeline 6 will enter the interior of the filter tank 502 through the first through hole 503. Since the methanol is blocked by the connecting cover 504, the methanol will penetrate the through groove in the middle of the retaining ring 519 and enter the position between the filter tank 502 and the first filter element 507. At this time, the methanol penetrates the first filter element 507. The main function of the first filter element 507 here is to filter large particles of impurities, and at the same time, the methanol is dispersed and evenly penetrates the first filter element 507. After the methanol penetrates the first filter element 507, it will wrap the heat exchange tube 509, and enter the inner wall of the heat exchange tube 509 through the second through hole 510 in the middle of the heat exchange tube 509, and penetrate the second filter element again. 512, at this time, the second filter element 512 finely filters the methanol, and the filtered methanol enters the inner tube 505 through the second through hole 510 in the middle of the inner tube 505, and finally flows to the first pipeline 4 and flows out to the methanol oil rail 3. When the methanol wraps the heat exchange tube 509, the coolant that absorbs heat circulates in the circulation channel 513, the first connecting tube 514, the engine cooling liquid inlet pipe 515, the second connecting tube 516 and the engine cooling liquid outlet pipe 517, which makes the coolant evenly exchange heat with the methanol on the surface of the heat exchange tube 509, so that the methanol is heated. At the same time, the engine cooling liquid inlet pipe 515 will also contact with the methanol on the inner wall of the inner tube 505, thereby increasing the heat exchange time of the methanol, so that the methanol can quickly heat up, and the methanol can quickly reach the working temperature, thereby shortening the time for switching between gasoline and methanol. After that, the heated methanol is directly sprayed into the cylinder of the methanol fuel generator 2 to complete the switching between gasoline and methanol.

[0052] Embodiment 2

[0053] See also Figure 9-11 Different from the first embodiment, a seventh pipe 20 connected to the inside of the filter tank 502 is fixedly installed on the surface of the filter tank 502, a third drive pump 21 is fixedly installed at one end of the seventh pipe 20 away from the filter tank 502, and a second gasoline inlet pipe 22 is fixedly installed at the input end of the third drive pump 21, the second gasoline inlet pipe 22 is connected to the gasoline tank 24, and the first filter element 507 is a gasoline fine filter element.

[0054] A first three-way valve 520 is fixedly installed in the middle of the second pipeline 6, and a cache tank 521 connected to the inside of the first three-way valve 520 is fixedly installed at the right end of the first three-way valve 520, and a cache bellows 522 is fixedly installed on the inner wall of the cache tank 521 corresponding to the position of the first three-way valve 520, and a push plate 523 is fixedly installed on the end of the cache bellows 522 away from the position of the first three-way valve 520, and a return spring 524 is fixedly installed on the inner wall of the cache tank 521.

[0055] The retaining ring 519 is a solid annular structure to prevent the fuel that enters the filter tank 502 through the second pipe 6 and the first through hole 503 from entering the position between the first filter element 507 and the filter tank 502. The connecting cover 504 and the first end ring 506 are hollow structures to prevent the fuel that enters the filter tank 502 through the second pipe 6 and the first through hole 503 from entering the position between the first filter element 507 and the second filter element 512 through the hollow connecting cover 504 and the first end ring 506.

[0056] Working principle: before cold start during use, the third drive pump 21 and the first drive pump 8 work synchronously, and the first three-way valve 520 cuts off the connection between the middle part of the second pipeline 6, and at the same time, the second three-way valve 10 cuts off the connection between the fourth pipeline 11 and the methanol oil inlet pipe 12, and connects the fourth pipeline 11 with the third pipeline 9, so that the first drive pump 8 is connected to the buffer tank 521 through the second pipeline 6. At this time, the third drive pump 21 pumps the gasoline in the gasoline tank 24 into the seventh pipeline 20 through the second gasoline inlet pipe 22, and allows the gasoline to enter the filter tank 502 and pass through the first filter element 507. The first filter element 507 in this embodiment is a gasoline fine filter element. The gasoline can be finely filtered, and then the gasoline enters the heat exchange tube 509 and the inner tube 505. Since the methanol fuel generator 2 used methanol as fuel when it worked last time, that is, there is still methanol in the filter tank 502, which will affect the cold start of the methanol fuel generator 2. Therefore, the interior of the filter tank 502 is flushed with gasoline, and the methanol in the filter tank 502, the first pipeline 4, the methanol oil rail 3 and the third pipeline 9 is pumped into the cache tank 521 through the second pipeline 6 by the first driving pump 8 along with the gasoline, and the push plate 523 is continuously driven in the cache bellows 522 to squeeze the reset spring 524, so that the methanol and gasoline mixture is temporarily stored in the cache bellows 522. When the gasoline is flushed, the first three-way valve 520 cuts off the connection between the cache tank 521 and the second pipeline 6, and also cuts off the connection in the middle of the second pipeline 6, that is, the third driving pump 21 pumps the gasoline in the gasoline tank 24 into the methanol fuel rail 3 through the seventh pipeline 20, the fuel processing assembly and the first pipeline 4 through the second gasoline inlet pipe 22, and sprays it into the cylinder of the methanol fuel generator 2 through the methanol injector 7, so that the methanol fuel generator 2 can work stably. When the methanol fuel generator 2 is started, the first three-way valve 520 controls the fuel processing assembly to be connected with the cache tank 521 through the second pipeline 6, and under the action of the reset stretching of the reset spring 524, the The mixture of gasoline and methanol in the buffer bellows 522 is continuously injected into the filter tank 502 and slowly mixed with the gasoline in the filter tank 502, so that the proportion of methanol in the fuel continues to increase. After the mixture in the buffer tank 521 is emptied, the first three-way valve 520 cuts off the connection between the fuel processing component and the buffer tank 521, and makes the middle part of the second pipeline 6 in a connected state, and adjusts the pumping ratio between the first drive pump 8 and the third drive pump 21, so that the proportion of methanol gradually increases, until methanol completely replaces gasoline, that is, the third drive pump 21 does not work at all, so that the fuel switching is relatively gentle, avoiding the occurrence of unstable operation of the methanol fuel generator 2;

[0057] When gasoline and methanol are mixed in the fuel processing assembly, the gasoline will evenly fill the surface of the heat exchange tube 509 after passing through the first filter element 507, and will evenly mix with the methanol on the surface of the heat exchange tube 509. Due to the presence of the third drive pump 21, when the third drive pump 21 is not working, the fuel inside the seventh pipeline 20 will not flow back to the second gasoline inlet pipe 22, so methanol will not pass through the first filter element 507. When methanol and gasoline are mixed on the surface of the heat exchange tube 509, the coolant circulating in the circulating flow channel 513, the first connecting pipe 514, the engine cooling inlet pipe 515, the second connecting pipe 516 and the engine cooling outlet pipe 517 will transfer heat to the mixed liquid of methanol and gasoline, further promoting the uniform mixing of methanol and gasoline, avoiding the stratification of methanol and gasoline in winter, and further causing the unstable operation of the methanol fuel generator 2.
