Description

Technical Field

[0001] This application relates to the field of generator set technology, and in particular to an anti-scalding heat dissipation device for a methanol generator set. Background Art

[0002] A methanol generator set is a device that uses methanol as fuel for power generation. Its working principle is that methanol combustion generates heat energy, which is converted into mechanical energy, and then the mechanical energy drives the generator to generate electricity. When methanol burns, it will produce pollutants such as carbon dioxide, carbon monoxide, formaldehyde, and nitrogen oxides. However, compared with traditional petroleum fuels, its pollutants are usually less, so it is more suitable for places such as camping, factories, hospitals, schools, offices, etc., especially for occasions that require portable power sources.

[0003] In related technologies, the Chinese utility model patent with the authorization publication number CN212690179U discloses a small portable generator set powered by methanol, which includes a methanol fuel tank, a methanol engine, a permanent magnet generator, and a battery pack. The methanol fuel tank is connected to the methanol engine through a pipeline. A crankshaft is provided on the methanol engine, and the crankshaft of the methanol engine is connected to the rotating shaft of the permanent magnet generator through a belt drive. The battery pack is electrically connected to the permanent magnet generator. Methanol in the methanol fuel tank enters the cylinder of the methanol engine after high-pressure atomization, and is fully mixed with air. Due to the upward extrusion of the cylinder piston, methanol is ignited, and the mixed gas burns violently, and the volume expands rapidly, pushing the piston downward to do work, driving the crankshaft to rotate. The crankshaft drives the rotating shaft of the permanent magnet generator to rotate through a belt. According to the principle of electromagnetic induction, the permanent magnet generator generates current and stores the electric energy in the battery pack. An exhaust silencer pipe is also connected to the methanol engine, and the gas generated after combustion in the methanol engine flows to the exhaust port through the exhaust silencer pipe. This small portable generator set can be used in the wild or places without effective power supply, and can provide effective power for small and medium-power electrical appliances, and can be used for household emergency lighting, outdoor lighting, mobile phone charging, mobile phone power bank charging, small-capacity battery charging, experimental teaching, etc.

[0004] In view of the above related technologies, the inventor found that high-temperature flue gas will be discharged after methanol combustion in the methanol engine, and in this solution, the exhaust silencer pipe and the engine exhaust port are directly exposed outside without any heat insulation measures. If the user accidentally touches this place during use, it is very easy to be scalded, which will cause damage to the user's physical health. Summary of the Invention

[0005] In order to prevent users from being scalded by the discharged high-temperature flue gas when using a methanol generator set and improve the use safety of the methanol generator set, this application provides an anti-scalding heat dissipation device for a methanol generator set.

[0006] The anti-scalding heat dissipation device for a methanol generator set provided by this application adopts the following technical solution: An anti-scalding heat dissipation device for a methanol generator set, including a methanol generator set containing a methanol fuel tank, an engine, a generator, a storage battery and an air filter. The methanol fuel tank and the engine cylinder are connected through a pipeline, and the air filter and the engine cylinder are also connected through a pipeline. An exhaust pipe is arranged at the exhaust port of the engine cylinder, and a muffler is installed on the exhaust pipe. The engine crankshaft and the generator rotating shaft are connected by a belt, and the generator is electrically connected to the storage battery; it further includes a heat dissipation box. The methanol generator set is arranged in the heat dissipation box. Heat dissipation openings are provided on all four sides of the heat dissipation box, and electric louvers are installed in all four heat dissipation openings. The top of the heat dissipation box is open and a water collecting tank is installed. The water in the water collecting tank is used to cool the exhaust pipe.

[0007] By adopting the above technical solution, when the generator set works, the air filter absorbs air and dust-removes and purifies it. Methanol in the methanol fuel tank and the purified air enter the engine cylinder through the pipeline for combustion. The cylinder drives the cylinder piston to do work through combustion, thereby driving the engine crankshaft to rotate. The engine crankshaft and the rotating shaft of the generator are connected by belt drive. According to the principle of electromagnetic induction, the generator generates current. The generator is electrically connected to the storage battery, so that electric energy can be stored in the storage battery for use; When the methanol generator set works, adjust the electric louvers to make the blades of the electric louvers rotate to a suitable angle, so as to facilitate the heat dissipation of the generator set and at the same time avoid the user being scalded by contacting the engine exhaust pipe; at the same time, the water in the water collecting tank can cool the exhaust pipe, further improving the heat dissipation effect of the exhaust pipe, effectively avoiding the user being scalded by the high-temperature flue gas discharged when using the methanol generator set, and improving the use safety of the methanol generator set.

[0008] Optionally, a rainproof plate is rotatably connected to the top opening of the heat dissipation box. A control panel is arranged on the bottom surface of the rainproof plate. An electric louver adjustment panel is installed on the control panel. The electric louver adjustment panel is electrically connected to four groups of electric louvers. A support rod is arranged in the heat dissipation box. When the rainproof plate abuts against the support rod, the control panel is located inside the heat dissipation box.

[0009] By adopting the above technical solution, the electric louver adjustment panel is electrically connected to four groups of electric louvers, which can be used to adjust the rotation angle of the electric louver blades and the lifting of the curtains. When the methanol generator set works, the electric louvers can be adjusted to open their blades to facilitate the heat dissipation of the unit. When it rains outdoors during use, the electric louvers can be adjusted to close their blades to seal the heat dissipation openings to prevent rainwater from entering the unit and damaging parts; When the control panel needs to be operated, flip the rain shield so that the control panel faces upward for easy operation of the control panel; when the control panel does not need to be operated, the rain shield can be flipped so that the control panel faces downward. At this time, the control panel is located inside the heat dissipation box, thereby protecting the control panel and preventing accidental touch.

[0010] Optionally, a heat conduction pipe is provided below the water collection tank. The heat conduction pipe is connected to the water collection tank through a pipeline. The material of the heat conduction pipe is set to copper, and the exhaust pipe is wound around the heat conduction pipe.

[0011] By adopting the above technical solution, the water collection tank can be used to collect rainwater or store water as a cooling medium. The water source in the water collection tank enters the heat conduction pipe through a pipeline. Since the exhaust pipe is wound around the heat conduction pipe, the cooling water in the heat conduction pipe can absorb the heat of the exhaust pipe, causing the temperature of the flue gas in the exhaust pipe to drop, thereby achieving the cooling and heat dissipation of the flue gas; at the same time, since the material of the heat conduction pipe is set to copper, the heat conduction effect can be accelerated, and the heat dissipation effect on the exhaust pipe can be improved.

[0012] Optionally, a methanol gasification tank is further provided between the methanol fuel tank and the engine. The liquid inlet of the methanol gasification tank is connected to the methanol fuel tank through a pipeline, and the gas outlet of the methanol gasification tank is connected to the engine cylinder through a pipeline. One end of the heat conduction pipe is connected to a heating hose, and the heating hose is wound around the methanol gasification tank.

[0013] By adopting the above technical solution, the water in the heat conduction pipe absorbs heat and then flows into the heating hose. The heating hose heats the formaldehyde gasification tank, causing the methanol to change from a liquid to a gas, thereby improving the combustion degree of methanol and air in the engine cylinder and increasing the utilization rate of methanol.

[0014] Optionally, a first filter tank and a second filter tank are further provided in the heat dissipation box. The exhaust pipe is connected to the first filter tank, and the first filter tank and the second filter tank are connected through a pipeline. A solid adsorbent is provided in the first filter tank, and a liquid adsorbent is provided in the second filter tank. The solid adsorbent is used to absorb harmful gases with a molecular diameter larger than that of methanol molecules, and the liquid adsorbent is used to absorb harmful gases with a molecular diameter smaller than that of methanol molecules.

[0015] By adopting the above technical solution, the harmful gases in the flue gas with a molecular diameter larger than that of methanol molecules are adsorbed by the solid adsorbent in the first filter tank, and then the harmful gases in the flue gas with a molecular diameter smaller than that of methanol molecules are adsorbed by the liquid adsorbent in the second filter tank, thereby completing the adsorption of harmful gases other than methanol in the flue gas. Using a combination of physical adsorption and chemical adsorption methods can improve the absorption effect of pollutants in the flue gas and prevent the flue gas from being discharged into the atmosphere to pollute the environment.

[0016] Optionally, the other end of the heat conduction pipe is also connected to a heating hose, which is wound around the second filtration tank, and the top of the second filtration tank is connected to the engine cylinder through a pipeline.

[0017] By adopting the above technical solution, in the second filtration tank, methanol dissolves in the solution. The second filtration tank is heated by the heating hose to vaporize methanol, thus facilitating the recovery of methanol. After methanol is vaporized, it enters the engine cylinder through the pipeline for combustion. This not only avoids the emission of flue gas and reduces air pollution, but also recovers the methanol gas in the flue gas, avoids the waste caused by incomplete combustion of methanol, and saves methanol fuel.

[0018] Optionally, temperature control valves are provided between the heat conduction pipe and the two heating hoses.

[0019] By adopting the above technical solution, temperature control valves are provided between the heat conduction pipe and the two heating hoses to monitor the water temperature in the heat conduction pipe. When the cooling water temperature in the heat conduction pipe is heated to the boiling point of methanol, the temperature control valve opens to allow the hot water to flow into the heating hose, so as to facilitate the heating of methanol in the methanol vaporization tank and the second filtration tank.

[0020] Optionally, a drainage tank is further provided in the heat dissipation box. The two heating hoses are both connected to the inside of the drainage tank. A water pump is provided on the water collection tank. The water inlet of the water pump is connected to the drainage tank through a pipeline, and the water outlet of the water pump is connected to the inside of the water collection tank.

[0021] By adopting the above technical solution, the water in the two heating hoses cools down after heating methanol and is then discharged into the drainage tank. The water in the drainage tank is pumped into the water collection tank by the water pump and then re-enters the heat conduction pipe for heating, thus completing the circulation of the cooling water source.

[0022] Optionally, an electric heating wire is wound around the methanol vaporization tank, and the electric heating wire is electrically connected to the storage battery.

[0023] By adopting the above technical solution, when the engine is just started, the methanol liquid in the methanol vaporization tank can be heated by the electric heating wire at this time, so as to vaporize methanol in time and facilitate the full combustion of methanol. When the engine has been working for a period of time, the electric heating wire stops heating. At this time, the high-temperature heat of the flue gas can be absorbed by the cooling water source for heating, thus making good use of the waste heat of the flue gas and effectively saving energy.

[0024] Optionally, the blades of the electric louver include a support frame and a heat-insulating cloth, and the heat-insulating cloth and the support frame are bonded by magic tape. The heat-insulating cloth is made of aluminized pearl cotton material.

[0025] By adopting the above technical solution, when the temperature is relatively low in winter, the electric louver can be closed. At this time, the heat preservation cloth plays a heat preservation role for the engine set, so as to reduce the situation of cold start of the engine and improve the full combustion degree of methanol fuel. When the temperature is relatively high in summer, the heat preservation cloth can be torn off to improve the ventilation and heat dissipation effect inside the unit.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the methanol generator set is working, adjust the electric louver so that the blades of the electric louver rotate to an appropriate angle, which is convenient for dissipating heat from the generator set. At the same time, it can prevent users from being scalded by contacting the engine exhaust pipe. At the same time, the water in the water collecting tank can cool the exhaust pipe, further improving the heat dissipation effect of the exhaust pipe, effectively preventing users from being scalded by the high-temperature flue gas discharged when using the methanol generator set, and improving the use safety of the methanol generator set. 2. The electric louver adjustment panel is electrically connected to the four groups of electric louvers and can be used to adjust the rotation angle of the electric louver blades and the lifting of the curtain. When the methanol generator set is working, the electric louver can be adjusted to open its blades for the unit to dissipate heat. When it rains outdoors, the electric louver can be adjusted to close its blades to seal the heat dissipation port to prevent rainwater from entering the unit and damaging parts. 3. When the engine is just started, the methanol liquid in the methanol gasification tank can be heated by the heating wire at this time, so that the methanol can be gasified in time for full combustion of methanol. When the engine has worked for a period of time, the heating wire stops heating. At this time, the high-temperature heat of the flue gas can be absorbed by the cooling water source for heating, so that the waste heat of the flue gas is better utilized and energy is effectively saved.

[0029] The following further describes the present application in detail Figure 1-7 in conjunction with the attached drawings.

[0030] An anti-scalding heat dissipation device for a methanol generator set is disclosed in an embodiment of the present application.

[0031] Referring to Figure 1 and Figure 2 , an anti-scalding heat dissipation device for a methanol generator set includes a methanol generator set 1, a radiator box 2, a heat absorption component 4 and a flue gas filtration component 3. The methanol generator set 1, the heat absorption component 4 and the flue gas filtration component 3 are all located in the radiator box 2. When the engine 12 operates, the radiator box 2 dissipates heat from the flue gas discharged by the engine 12. At the same time, the heat absorption component 4 absorbs the heat of the flue gas to reduce the temperature of the flue gas and prevent the user from being scalded by the flue gas discharged by the engine 12. The flue gas filtration component 3 filters and removes impurities from the flue gas and recovers the unburned methanol therein, thereby improving the utilization rate of methanol fuel and saving resources.

[0032] Referring to Figure 2 and Figure 3, the methanol generator set 1 includes a methanol fuel tank 11, an engine 12, a generator 13, a storage battery 14, an air filter 15 and a methanol gasification tank 16. A support frame 21 is fixedly connected to the inner bottom surface of the heat dissipation box 2. The methanol fuel tank 11, the methanol gasification tank 16 and the storage battery 14 are all fixedly connected above the support frame 21. The engine 12, the generator 13 and the air filter 15 are all located below the support frame 21. The air filter 15 is communicated with the cylinder of the engine 12 through a pipeline, and a four-way valve 17 is connected thereto. The air filter 15 is used to filter impurities such as dust in the air and convey the filtered air into the cylinder of the engine 12. The liquid inlet of the methanol gasification tank 16 is connected to the methanol fuel tank 11 through a pipeline, and the methanol fuel tank 11 is located above the methanol gasification tank 16. The gas outlet of the methanol gasification tank 16 is connected to the four-way valve 17 through a pipeline. After the heat absorption component 4 absorbs the heat of the flue gas, it uses this heat to heat the methanol liquid in the methanol gasification tank 16 to vaporize the methanol. The vaporized methanol enters the cylinder of the engine 12 together with the air and burns.

[0033] Refer to Figure 3 , an electric heating wire 18 is also installed outside the methanol gasification tank 16. The storage battery 14 is electrically connected to the electric heating wire 18. When the engine 12 is just started, the methanol gasification tank 16 can be heated by the electric heating wire 18 at this time to vaporize the methanol liquid therein. After the engine 12 has worked for a period of time, the electric heating wire 18 stops heating at this time, and the methanol gasification tank 16 is heated by the heat absorption component 4.

[0034] Refer to Figure 3 , the cylinder of the engine 12 drives the cylinder piston to do work through combustion, thereby driving the crankshaft of the engine 12 to rotate. The crankshaft of the engine 12 is connected to the rotating shaft of the generator 13 through a belt drive. According to the principle of electromagnetic induction, the generator 13 generates current. The generator 13 is electrically connected to the storage battery 14, so that electric energy can be stored in the storage battery 14 for use. A exhaust pipe 191 is fixedly connected to the exhaust port of the engine 12. The flue gas discharged from the exhaust pipe 191 is introduced into the flue gas filtering component 3, and a muffler 192 is installed on the exhaust pipe 191 to reduce the noise during exhaust.

[0035] Refer to Figure 1 and Figure 4, the four sides of the heat dissipation box 2 are each provided with a heat dissipation opening 22 for heat dissipation. An electric louver 23 is installed at each heat dissipation opening 22. The electric louver 23 is a conventional technology and will not be elaborated here. When the methanol generator set 1 is working, the blades of the electric louver 23 are in the open state to facilitate the heat dissipation of the unit. When it rains outdoors, the electric louver 23 is in the closed state to seal the heat dissipation opening 22 to prevent rainwater from entering the unit and damaging the parts. The blades of the electric louver 23 include a support frame 231 and a heat preservation cloth 232. The heat preservation cloth 232 and the support frame 231 are bonded by magic tape. The heat preservation cloth 232 is made of aluminized pearl cotton material. When the temperature is relatively low in winter, the electric louver 23 can be closed to play a heat preservation role for the methanol engine set 1, so as to reduce the cold start situation of the engine 12 and improve the full combustion degree of the methanol fuel. When the temperature is relatively high in summer, the heat preservation cloth 232 can be torn off to improve the ventilation and heat dissipation effect inside the unit.

[0036] Refer to Figure 1 and Figure 5 , the top of the heat dissipation box 2 is open and is rotatably connected with two rain-proof plates 24 for shielding rain inside the heat dissipation box 2 to prevent the methanol generator set 1 from being damaged. The two rain-proof plates 24 are symmetrically arranged and the symmetry plane is coplanar with the symmetry plane of the heat dissipation box 2. The adjacent sides of the two rain-proof plates 24 are rotatably connected inside the top opening of the heat dissipation box 2, and the sides away from each other are in contact with the inner wall of the heat dissipation box 2. A support rod 25 is arranged below each rain-proof plate 24. The support rod 25 is fixedly connected to the inside of the heat dissipation box 2. When the rain-proof plate 24 is in the horizontal state, the support rod 25 supports the rain-proof plate 24. A control panel 26 is fixedly connected to the bottom surface of one of the rain-proof plates 24. Control buttons such as an engine 12 on-off switch, a charging socket, and an electric louver adjustment panel 261 are installed on the control panel 26. The electric louver adjustment panel 261 is electrically connected to the four groups of electric louvers 23 for controlling the rotation angle of the blades of the electric louvers 23 and the lifting of the curtains. Handles 27 are fixedly connected to the top surfaces of the two rain-proof plates 24. When it is necessary to operate the control panel 26, hold the handle 27 and rotate the rain-proof plate 24 to turn the rain-proof plate 24 so that the control panel 26 faces upward, thereby operating the control panel 26. When it is not necessary to operate the control panel 26, the rain-proof plate 24 can be turned so that the control panel 26 faces downward. At this time, the control panel 26 is located inside the heat dissipation box 2, thereby protecting the control panel 26 and preventing accidental touch. The methanol fuel tank 11 is located below the rain-proof plate 24 away from the control panel 26. When the rain-proof plate 24 is turned over and opened, methanol fuel can be added to the methanol fuel tank 11.

[0037] Refer to Figure 1 , to facilitate the movement of the heat dissipation box 2, four moving wheels 28 are installed at the bottom of the heat dissipation box 2 to facilitate the movement of the methanol generator set 1. At the same time, the moving wheels 28 can be locked to facilitate the fixation of the heat dissipation box 2.

[0038] Reference Figure 3 and Figure 6 Figure 6 , the flue gas filtration assembly 3 includes a first filter tank 31 and a second filter tank 32. The outlet end of the exhaust pipe 191 communicates with the first filter tank 31. The first filter tank 31 and the second filter tank 32 are communicated through a pipeline. The top of the second filter tank 32 and the four-way valve 17 are communicated through a pipeline. The flue gas in the exhaust pipe 191 enters the first filter tank 31 after being cooled by the heat absorption assembly 4. Both the first filter tank 31 and the second filter tank 32 are fixedly connected above the support frame 21. The first filter tank 31 stores a solid adsorbent, which is molecular sieve in this embodiment and can be used to absorb harmful gases with a molecular diameter larger than that of methanol molecules. The flue gas purified by the first filter tank 31 then enters the second filter tank 32. The second filter tank 32 stores a liquid adsorbent, which can react with harmful gases with a molecular diameter smaller than that of methanol molecules to absorb them. At the same time, methanol dissolves in the liquid adsorbent. At this time, the heat absorbed by the heat absorption assembly 4 is used to heat the second filter tank 32. After reaching the boiling point of methanol, methanol gasifies. The methanol gas is transported to the cylinder of the engine 12 through a pipeline, completing the recovery and utilization of methanol in the flue gas. This not only avoids the emission of flue gas, reduces air pollution, but also recovers the methanol gas in the flue gas, avoids the waste caused by incomplete combustion of methanol, and saves methanol fuel.

[0039] Reference Figure 2 、 Figure 3 and Figure 5 Figure 5 , the heat absorption assembly 4 includes a water collecting tank 42, a heat conduction pipe 43 and two heating hoses 45. A flow guide cylinder 41 is arranged between two rainproof plates 24. The flow guide cylinder 41 is arranged in the shape of an inverted quadrangular pyramid and is fixedly connected to the inner wall of the heat dissipation box 2. The water collecting tank 42 is located below the flow guide cylinder 41. The opening area of the water collecting tank 42 is larger than the bottom opening area of the flow guide cylinder 41. The flow guide cylinder 41 is used to guide the water source entering the water collecting tank 42. Four hooks 411 are connected to the bottom of the flow guide cylinder 41 by ropes. Four hanging rings 421 are fixedly connected to the inner bottom wall of the water collecting tank 42 corresponding to the four hooks 411. When installing the water collecting tank 42, the hanging rings 421 are hung on the corresponding hooks 411, so as to install the water collecting tank 42 below the flow guide cylinder 41. The water collecting tank 42 can be used to collect rainwater or store water source as the cooling medium for the flue gas.

[0040] Reference Figure 3 and Figure 7, a water outlet 422 is provided at the bottom of the water collection tank 42. The heat conduction pipe 43 is located below the water collection tank 42 and is connected to the water outlet 422 through a pipeline. The length direction of the heat conduction pipe 43 is horizontally arranged, and the material of the heat conduction pipe 43 is set as copper for easy heat conduction. The exhaust pipe 191 is evenly wound around the heat conduction pipe 43. After the water source in the water collection tank 42 enters the heat conduction pipe 43, the flue gas heats the cooling water in the heat conduction pipe 43. After the cooling water absorbs heat, the temperature of the flue gas drops, thereby realizing the cooling of the flue gas. Both ends of the heat conduction pipe 43 are respectively connected to two heating hoses 45. One of the heating hoses 45 is evenly wound around the tank body of the second filter tank 32 for heating the solution containing methanol to vaporize the methanol. The other heating hose 45 is evenly wound around the methanol vaporization tank 16 for heating the methanol liquid in the methanol vaporization tank 16 to vaporize the methanol liquid, thereby improving the degree of full combustion of methanol in the cylinder of the engine 12. The materials of the methanol vaporization tank 16 and the second filter tank 32 are both set as copper to improve the heat conduction effect and accelerate the vaporization of methanol. In addition, temperature control valves 44 are installed at both ends of the heat conduction pipe 43. When the cooling water in the heat conduction pipe 43 is heated to a temperature higher than the boiling point of methanol, the temperature control valve 44 opens, allowing the water to flow into the two heating hoses 45.

[0041] Referring to Figure 7 , the heat absorption assembly 4 further includes a drainage tank 46. The drainage tank 46 is located below the support frame 21. Both heating hoses 45 are connected to the inside of the drainage tank 46. After the water with a higher temperature in the heating hoses 45 heats the methanol vaporization tank 16 and the second filter tank 32, the temperature drops and then drains into the drainage tank 46 at this time. A water pump 47 is installed at the bottom of the water collection tank 42. The water inlet of the water pump 47 is connected to the bottom of the drainage tank 46 through a pipeline, and the water outlet 422 of the water pump 47 is connected to the inside of the water collection tank 42. The water in the drainage tank 46 is pumped into the water collection tank 42 by the water pump 47 and then enters the heat conduction pipe 43 again for heating to complete the circulation of the cooling water source.

[0042] The implementation principle of the anti-scalding and heat dissipation device of a methanol generator set in an embodiment of the present application is as follows: Flip the rainproof board 24 to make the control panel 26 face upward, start the engine 12 on-off switch, and the engine 12 starts to work. At the same time, the heating wire 18 heats the methanol vaporization tank 16 to vaporize the methanol liquid in the methanol vaporization tank 16. Adjust the electric louver adjustment panel 261 to rotate the blades of the electric louver 23 to an appropriate angle for facilitating the heat dissipation of the engine 12, and at the same time, it can prevent the user from being scalded by contacting the exhaust pipe 191 of the engine 12.

[0043] When the engine 12 is operating, the methanol liquid in the methanol fuel tank 11 flows into the methanol gasification tank 16 through a pipeline. The heating wire 18 heats the methanol gasification tank 16 to gasify the methanol. At the same time, the air filter 15 absorbs air and purifies it by removing dust. The methanol gas and the purified air enter the cylinder of the engine 12 through a pipeline and burn. The cylinder of the engine 12 drives the cylinder piston to do work through combustion, thereby driving the crankshaft of the engine 12 to rotate. The crankshaft of the engine 12 is connected to the rotating shaft of the generator 13 through a belt drive. According to the principle of electromagnetic induction, the generator 13 generates electric current. The generator 13 is electrically connected to the storage battery 14, so that the electric energy can be stored in the storage battery 14 for use.

[0044] After the engine 12 has been operating for a period of time, the heating wire 18 stops heating, and the water in the water collection tank 42 flows into the heat conduction pipe 43. At this time, the flue gas discharged from the engine 12 enters the exhaust pipe 191. The cooling water in the heat conduction pipe 43 absorbs the heat of the flue gas, causing the temperature of the flue gas to drop and the temperature of the cooling water to rise. When the temperature of the cooling water rises above the boiling point of methanol, the temperature control valve 44 opens. At this time, the water in the heat conduction pipe 43 enters the two heating hoses 45. The hot water in one heating hose 45 heats the methanol liquid in the methanol gasification tank 16 to gasify the methanol.

[0045] The cooled flue gas enters the first filtration tank 31. The solid adsorbent in the first filtration tank 31 absorbs the harmful gases in the flue gas with a molecular diameter larger than that of methanol molecules. The flue gas after the first step of impurity removal then enters the second filtration tank 32. The liquid adsorbent in the second filtration tank 32 reacts with the harmful gases in the flue gas with a molecular diameter smaller than that of methanol molecules and absorbs them. At the same time, the methanol in the flue gas dissolves in the liquid adsorbent. At this time, the hot water in the other heating hose 45 heats the second filtration tank 32. When heated to reach the boiling point of methanol, the methanol gasifies and is then transported to the cylinder of the engine 12 through a pipeline, completing the recovery and utilization of methanol in the flue gas. This not only avoids the emission of flue gas, reduces air pollution, but also recovers the methanol gas in the flue gas, avoids the waste caused by incomplete combustion of methanol, and saves methanol fuel.

[0046] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
