[0002] A gas engine is a heat engine that uses fuel combustion to heat a circulating working fluid and converts thermal energy into mechanical energy. After the Industrial Revolution, with the development and use of mechanical equipment, gas engines have become popular all over the world as a source of energy for mechanical equipment. Gas engines require fuel combustion and heating to convert thermal energy, and unavoidable heat will follow. As for this, in the process of waste heat treatment, the thermal insulation structure of the delivery pipe is crucial. The current thermal insulation structure of the waste heat delivery pipe generally uses thickened pipe walls to reduce the impact of waste heat on the outside of the delivery pipe.

[0006] A number of screens evenly distributed in the delivery pipe can absorb the waste heat generated by the engine and discharged into the delivery pipe, and then the heat energy is converted into electrical energy through a heat conduction generator connected to the screen. The material of the screen here is a heat-conducting material, which can do a good job of heat conduction, thus facilitating the conversion work of the heat conduction generator. The water pump electrically connected to the heat conduction generator can start the pumping work, and the pumped water resources can be discharged into the drainage pipe to play a heat insulation role, thus achieving the purpose of using waste heat to carry out heat insulation work.

[0010] Preferably, the delivery pipe is provided with a second through-tube, one end of which is connected to the exhaust fan, and the other end of which is connected to the exhaust pipe.

[0025] An exhaust pipe 4 and an exhaust fan 10 are installed on the delivery pipe 2. One end of the exhaust pipe 4 is connected to the exhaust fan 10, and the other end of the exhaust pipe 4 is connected to the drain pipe 3. The drain pipe 3 is placed between the delivery pipe 2 and the exhaust pipe 4. A switch 2 11 is installed on the exhaust fan 10. The exhaust fan 10 is electrically connected to the heat conduction generator 8 through the switch 2 11. The exhaust pipe 4 is connected to the delivery pipe 2 through the screen 1 9. A through pipe 2 12 is provided on the delivery pipe 2. One end of the through pipe 2 12 is connected to the exhaust fan 10, and the other end of the through pipe 2 12 is connected to the exhaust pipe 4. The exhaust pipe 4 is provided with a screen 14 made of heat-insulating material. The screen 14 is placed between the drain pipe 3 and the exhaust pipe 4. One end of the exhaust pipe 4 is connected to the exhaust fan 10 through the through pipe 12. The other end of the exhaust pipe 4 is connected to the drain pipe 3 through the screen 14. The through pipe 12 is provided with an opening 15. The opening 15 is placed on the through pipe 12 between the drain pipe 3 and the exhaust pipe 4. Figure 3 , Figure 4 As shown, the exhaust pipe 4 is provided with a plurality of openings 16, which are evenly distributed on the exhaust pipe 4, and the screen 9 is provided with a hard block 18, one end of the hard block 18 is placed in the exhaust pipe 4, and the other end of the hard block 18 is connected to the screen 9, and the hard block 18 is provided with a nut 17, and the cross-sectional diameter of the nut 17 is larger than the cross-sectional diameter of the opening 16, and the screen 9 is detachably connected to the nut 17 through the hard block 18.

[0026] like Figure 5 As shown, the heat conduction generator 8 is provided with a plurality of connection blocks 19, which are evenly distributed on the outer surface of the heat conduction generator 8. The heat conduction generator 8 is connected to the exhaust pipe 4 through the connection blocks 19, and there is a gap between the heat conduction generator 8 and the exhaust pipe 4. It also includes a power supply 20, which is electrically connected to the heat conduction generator 8, the water pump 5 is electrically connected to the power supply 20 through the switch 1 7, and the exhaust fan 10 is electrically connected to the power supply 20 through the switch 2 11. The outer surface of the combustion engine 1 is provided with a plurality of heat insulation blocks 21, which are evenly distributed, and the water pump 5 and the power supply 20 are both connected to the combustion engine 1 through the heat insulation blocks 21.

[0027] First, connect the water pump 13 installed on the water pump 5 electrically connected to the heat conduction generator 8 with the drain pipe 3, and ensure that the water pump 5 is connected to the drain pipe 3 through the through pipe 6 on the delivery pipe 2, so that the water resources in the drain pipe 3 can circulate among the water pump 5, the water pump 13 and the drain pipe 3 during operation. Then, start the engine 1, the engine 1 will generate heat and the waste heat will be transported to the delivery pipe 2. At this time, manually click the switch 7 on the water pump 5 connected to the engine 1 through the insulation block 21 on the engine 1, so that the water pump 5 starts the work of circulating the water resources in the drain pipe 3. This allows the water resources in the drain pipe 3 to have a heat insulation effect. The heat insulation block 21 here can be made of wood blocks, which can better prevent the heat from the engine 1 from affecting the water pump 5. The power supply for the water pump 5 is the heat conduction generator 8 connected to the inner wall of the exhaust pipe 4, which is affected by the waste heat discharged from the delivery pipe 2 and converted into electricity. A number of connecting blocks 19 are evenly installed on the inner wall of the exhaust pipe 4, and there is a gap between the heat conduction generator 8 and the exhaust pipe 4. This not only ensures a close connection between the exhaust pipe 4 and the heat conduction generator 8, but also allows the items in the delivery pipe 2 to flow smoothly, which is safe and practical.

[0028] Then manually click the switch 11 on the exhaust fan 10 on the conveying pipe 2, so that the exhaust fan 10 uses the electric resources generated by the heat conduction generator 8 electrically connected thereto to generate wind and blow it into the exhaust pipe 4 through the through pipe 12 connected to the exhaust fan 10 on the conveying pipe 2. Under the action of the wind, part of the residual heat in the conveying pipe 2 will be dissipated through the exhaust pipe 4. The drain pipe 3 is placed between the conveying pipe 2 and the exhaust pipe 4. In addition, a screen 14 that can be connected to the drain pipe 3 is installed on the exhaust pipe 4. In this way, under the action of the exhaust pipe 4, the water resources in the drain pipe 3 are affected. The probability of being affected by residual heat in the conveying pipe 2 is smaller, and the material of the screen 14 is a heat-insulating material, which further enhances the effect of the drain pipe 3 and the exhaust pipe 4 not affecting each other. The screen 14 can use a wooden board with openings, which not only has a good heat insulation effect, but also ensures the stability of the connection between the exhaust pipe 4 and the drain pipe 3. In order to make the exhaust pipe 4 and the drain pipe 3 not affect each other better, an opening 15 is set on the through pipe 12 between the drain pipe 3 and the exhaust pipe 4, so that the wind generated by the exhaust fan 10 is blown into the gap between the exhaust pipe 4 and the drain pipe 3 through the opening 15.

[0029] In the operation of the heat transfer generator 8 generating electricity by waste heat, the heat in the delivery pipe 2 is directly directed to the heat transfer generator 8 from the combustion engine 1, and a plurality of screens 9 are evenly installed in the delivery pipe 2. The waste heat of the delivery pipe 2 will also affect the screen 9. In this way, the heat transfer generator 8 and the screen 9 can be closely connected so that the heat on the screen 9 can enhance the effect of the heat transfer generator 8. The material of the screen 9 is a heat conductive material, which has a good heat conduction effect. At the same time, the screen 9 can make the exhaust pipe 4 and the delivery pipe 2 more firmly connected. The material of the screen 9 A copper plate with openings can be selected, which is stable and reliable. Several openings 16 are evenly distributed on the exhaust pipe 4, and a corresponding hard block 18 is also connected to the screen 9. One end of the hard block 18 is placed in the exhaust pipe 4, and the other end is connected to the screen 9. Then a nut 17 with a cross-sectional diameter larger than the cross-sectional diameter of the opening 16 is connected to the hard block 18 in the exhaust pipe 4. In this way, the screen 9 can be more stable and will not move around at will. The hard block 18 and the nut 17 can be provided with corresponding threads, which are not only tight and safe when connected, but also convenient and easy to disassemble.

[0030] However, when the combustion engine 1 just starts to work, the heat conduction generator 8 does not generate electricity by heat, so the water pump 5 and the exhaust fan 10 have no source of electricity when working. In this way, a power supply 20 electrically connected to the heat conduction generator 8 is required. The power supply 20 can store the electricity generated by the heat conduction generator 8 in it at ordinary times, and the water pump 5 can be electrically connected to the power supply 20 through switch 1 7, and the exhaust fan 10 can be electrically connected to the power supply 20 through switch 2 11. In this way, when the water pump 5 needs to work, click switch 1 7 to use the electricity stored in the power supply 20. When the exhaust fan 10 needs to work, click switch 2 11 to use the electricity stored in the power supply 20. It is convenient and practical.
