Description

Technical Field

[0001] The invention relates to the technical field of heat recovery, in particular to a device for recovering heat from exhaust gas of an internal combustion engine. Background Art

[0002] The internal combustion engine exhaust heat recovery technology is an innovative method to efficiently utilize the exhaust heat energy generated during the operation of the internal combustion engine. This technology captures the large amount of heat energy contained in the exhaust gas of the internal combustion engine and uses advanced conversion mechanisms such as thermoelectric effect and organic Rankine cycle (ORC) to convert this part of heat energy into reusable energy forms such as electricity and heat. This not only significantly improves the overall energy utilization efficiency of the internal combustion engine and reduces dependence on fossil fuels, but also effectively reduces the negative impact of exhaust emissions on the environment and promotes green and sustainable development.

[0003] In many fields such as transportation, industrial production and energy utilization, the internal combustion engine exhaust heat recovery technology has shown great application potential and value. In the existing internal combustion engine exhaust recovery technology, heat recovery power generation devices play a vital role. They achieve effective energy reuse by cleverly converting exhaust heat energy into electrical energy.

[0004] However, there is a problem in this process, that is, the existing temperature difference power generation device itself does not have the ability to directly process the carbon particles in the exhaust gas. Therefore, in order to ensure power generation efficiency and equipment safety, a pre-filter device must be additionally configured to intercept and remove these harmful particles. This pre-filtering link adds an additional operational burden, and it requires staff to perform regular maintenance inspections and filter material replacements. This process is not only time-consuming and labor-intensive, but also significantly increases the cost of using the overall heat recovery power generation system, including labor costs, material costs, and potential downtime costs. For this reason, we propose an internal combustion engine exhaust heat energy recovery and utilization device. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1-Figure 10 The present invention provides a technical solution: an internal combustion engine exhaust heat energy recovery and utilization device, comprising an exhaust pipe 1, a heat exchange chamber 2 and a temperature difference power generation device 3, and also comprising a filter plate 4, wherein the filter plate 4 is located in the heat exchange chamber 2, and the filter plate 4 is used to filter the carbon particles in the exhaust gas entering the temperature difference power generation device 3; a collecting rod 5, wherein the collecting rod 5 is located in the heat exchange chamber 2, and the collecting rod 5 is in contact with the filter plate 4, and the carbon particles filtered by the filter plate 4 are collected by the collecting rod 5.

[0035] The carbon powder collecting assembly 6 is arranged on the heat exchange chamber 2, and the collecting rod 5 is arranged on the carbon powder collecting assembly 6. The carbon powder collecting assembly 6 is used to control the collecting rod 5 to rotate on the filter plate 4 to collect the carbon particles filtered out from the filter plate 4.

[0036] The advantage of setting up the carbon powder collection component 6 is that when the heat energy in the exhaust gas is recovered for thermoelectric power generation, the carbon particles in the exhaust gas are automatically collected and cleaned, and there is no need for staff to manually clean them regularly. By automatically collecting the carbon particles in the exhaust gas, the deposition of these particles in the heat exchange bin 2 can be reduced, thereby keeping the inside of the heat exchange bin 2 clean and unobstructed, which helps the exhaust gas to flow through the heat exchange bin 2 more smoothly, improves the heat energy transfer efficiency, and then improves the power generation efficiency of the thermoelectric power generation device 3. Moreover, the long-term deposition of carbon particles in the heat exchange bin 2 will not only reduce the heat recovery efficiency, but may also cause wear and corrosion to the equipment, shortening its service life. Automatically collecting and removing these particles can effectively protect the heat exchange bin 2 and its related components, and extend the service life of the entire system.

[0037] The spraying mechanism 10 is disposed on the heat exchange chamber 2 , and the collected carbon particles are sprayed on the outer surface of the heat exchange chamber 2 by the spraying mechanism 10 to protect the outer surface of the heat exchange chamber 2 .

[0038] The advantage of setting up the spraying mechanism 10 is that the collected carbon particles can be sprayed onto the outer surface of the heat exchange bin 2 using high-speed gas, thereby serving as a protective layer for the heat exchange bin 2. The carbon particles have a certain hardness and chemical stability. When they are sprayed at high speed and adhere to the outer surface of the heat exchange bin 2, a protective coating can be formed. This coating can resist wear factors and corrosive substances that may exist in the external environment, thereby extending the service life of the heat exchange bin 2. At the same time, during the driving of the vehicle, the heat exchange bin 2 may be subjected to external physical shocks, such as particle impact, etc. The carbon particle coating serves as an additional protective layer that can absorb and disperse the impact energy and reduce damage to the heat exchange bin 2 body.

[0039] The carbon powder collection assembly 6 includes a recovery component 7 arranged in the heat exchange bin 2, and the carbon particles in the exhaust gas entering the heat exchange bin 2 are recovered by the recovery component 7. The recovery component 7 is provided with a driving component 8, and the driving component 8 is used to provide power for the movement of the collection rod 5. The driving component 8 is provided with a vibration component 9, and the vibration component 9 is used to knock the filter plate 4 when the collection rod 5 collects carbon particles.

[0040] The recovery component 7 includes a circulation chamber 71 arranged in the heat exchange chamber 2, a power generation chamber 72 is arranged in the heat exchange chamber 2, a mounting plate 73 is arranged in the power generation chamber 72, the mounting plate 73 is connected to the filter plate 4, and a collection chamber 74 is arranged on the mounting plate 73.

[0041] The benefit of setting up the recovery part 7 is that the traditional exhaust gas heat recovery system requires regular manual cleaning of the carbon particles in the heat exchange chamber 2, which not only increases the labor cost, but may also cause the equipment performance to decline due to untimely cleaning. This design greatly reduces the need for manual maintenance and reduces maintenance costs through an automated collection and utilization mechanism.

[0042] The driving member 8 includes a second mounting plate 81 arranged in the power generation chamber 72, a positioning plate 82 is arranged on the second mounting plate 81, a rotating shaft 83 is rotatably arranged on the positioning plate 82, a driving blade 84 is arranged at one end of the rotating shaft 83, and the rotating shaft 83 is connected to the collecting rod 5 at one end away from the driving blade 84.

[0043] The vibrating member 9 includes a circular groove 91 provided on the filter plate 4, a plurality of multi-stage telescopic rods 92 are arranged in the circular groove 91, a conical knocking block 93 is arranged on the multi-stage telescopic rod 92, the conical knocking block 93 is made of rubber, a return spring 94 is sleeved on the multi-stage telescopic rod 92, and a push rod 95 is rotatably arranged at both ends of the collecting rod 5, and the push rod 95 is slidably connected to the circular groove 91.

[0044] The advantage of the vibrating member 9 is that when the collecting rod 5 collects the carbon particles on the filter plate 4 , the filter plate 4 can be knocked to make the filter plate 4 vibrate, thereby improving the collection effect of the carbon particles.

[0045] During use, when the internal combustion engine is working and produces exhaust gas, the exhaust gas enters the heat exchange chamber 2 through the exhaust pipe 1. After the exhaust gas enters the heat exchange chamber 2, part of the exhaust gas enters the power generation chamber 72. When the exhaust gas reaches the power generation chamber 72, it contacts the filter plate 4. Under the action of the filter plate 4, the carbon particles in the exhaust gas are separated and attached to the filter plate 4. The separated gas flows to the temperature difference power generation device 3. When the exhaust gas enters the power generation chamber 72, it drives the driving blades 84 to rotate, and synchronously drives the rotating shaft 83 to rotate synchronously. When the rotating shaft 83 rotates, it drives the collecting rod 5 connected to it to rotate on the surface of the filter plate 4, so as to clean the carbon particles on the filter plate 4, and the cleaned carbon particles fall into the collecting chamber 74.

[0046] As the collecting rod 5 rotates, the pushing rods 95 at both ends of the collecting rod 5 are driven to slide in the circular groove 91. During the sliding process of the pushing rod 95 in the circular groove 91, the conical knocking block 93 is pushed to overcome the pressure of the return spring 94 and shrink, and rebounds and knocks the filter plate 4 after losing contact with the pushing rod 95, thereby causing the filter plate 4 to vibrate.

[0047] The spraying mechanism 10 includes a booster 11 arranged on the heat exchange chamber 2, and the booster 11 is used to increase the gas flow rate. The heat exchange chamber 2 is provided with a spraying part 12, and the carbon particles are sprayed onto the outer surface of the heat exchange chamber 2 by the spraying part 12. The spraying part 12 is provided with a storage part 13, and the storage part 13 is used to recover the non-working spraying part 12.

[0048] The supercharger 11 includes an air duct 111 disposed on the power generation chamber 72 , an airflow chamber 112 is disposed on the heat exchange chamber 2 , a Tesla valve 113 is disposed in the airflow chamber 112 , and the Tesla valve 113 is connected to the air duct 111 .

[0049] The benefit of setting the booster 11 is that it can increase the speed of gas ejection, thereby improving the effect of carbon particles adhering to the outer surface of the heat exchange chamber 2.

[0050] The spraying part 12 includes a mixing chamber 121 opened on the airflow chamber 112, and the mixing chamber 121 is connected to the Tesla valve 113. A connecting groove 122 is opened in the heat exchange chamber 2, and the connecting groove 122 is respectively connected to the collecting chamber 74 and the mixing chamber 121. A piston plate 123 is slidably arranged in the mixing chamber 121, and an extrusion spring 124 is arranged at one end of the piston plate 123, and one end of the extrusion spring 124 is connected to the mixing chamber 121. A storage chamber 125 is arranged on the airflow chamber 112, and a plurality of deflection shafts 126 are rotatably arranged in the storage chamber 125. A spraying pipe 127 is arranged on the deflection shaft 126, and an airflow pipe 128 is arranged on the storage chamber 125. One end of the airflow pipe 128 is connected to the mixing chamber 121, and a plurality of shunt pipes 129 are arranged on the airflow pipe 128, and the shunt pipe 129 is rotatably connected to the spraying pipe 127.

[0051] The spraying part 12 can use high-speed gas to spray the collected carbon particles onto the outer surface of the heat exchange bin 2 as a protective layer of the heat exchange bin 2. The carbon particles have a certain hardness and chemical stability. When they are sprayed at high speed and adhere to the outer surface of the heat exchange bin 2, a protective coating can be formed. This coating can resist wear factors and corrosive substances that may exist in the external environment, thereby extending the service life of the heat exchange bin 2.

[0052] The storage component 13 includes a power rack 131 arranged on the piston plate 123, and the power rack 131 is slidably connected to the mixing chamber 121. A fixed plate 132 is arranged on the outer side of the mixing chamber 121, and a rotating shaft 133 is rotatably arranged on the fixed plate 132. A rotating gear 134 engaged with the power rack 131 is arranged on the rotating shaft 133, and a transmission gear 1 135 is arranged on the rotating shaft 133. A worm 136 is rotatably arranged in the storage chamber 125, one end of the worm 136 passes through the storage chamber 125, and a transmission gear 2 137 engaged with the transmission gear 1 135 is arranged on one end of the worm 136. A worm wheel 138 engaged with the worm 136 is arranged on the deflection shaft 126.

[0053] The benefit of the storage member 13 is that it can control the recovery of the spray tube 127 when the internal combustion engine is not working, thereby avoiding damage to the spray tube 127 and further extending the service life of the spray tube 127.

[0054] After the exhaust gas passes through the temperature difference generator, it will enter the air duct 111, and then flow into the Tesla valve 113 from the air duct 111, and finally reach the mixing chamber 121. At this time, the air pressure in the mixing chamber 121 increases, pressing the piston plate 123, causing the piston plate 123 to move. During the displacement of the piston plate 123, the air flow pipe 128 is connected with the connecting groove 122 and the mixing chamber 121, so that the carbon particles in the collecting chamber 74 are mixed with the gas, and then enter the spray pipe 127 through the air flow pipe 128 and the diversion pipe 129, and then are sprayed to the outer surface of the heat exchange chamber 2 through the spray pipe 127. At the same time, because there is a continuous supply of exhaust gas injected into the power generation chamber 72 in the exhaust pipe 1, the air flow in the mixing chamber 121 will not flow back into the power generation chamber 72 through the connecting groove 122, and the carbon particles in the collecting chamber 74 will enter the mixing chamber 121 through the connecting groove 122 under the action of air pressure.

[0055] When the piston plate 123 moves, it drives the power rack 131 to move, and the power rack 131 moves and pushes the rotating gear 134 engaged with it to rotate. The rotation of the rotating gear 134 drives the rotating shaft 133 to rotate synchronously. The rotation of the rotating shaft 133 drives the transmission gear 1 135 to rotate. The rotation of the transmission gear 1 135 drives the transmission gear 2 137 engaged with it to rotate. The rotation of the transmission gear 2 137 drives the worm 136 to rotate. The rotation of the worm 136 drives the worm wheel 138 engaged with it to rotate. The rotation of the worm wheel 138 drives the deflection shaft 126 to rotate. The rotation of the deflection shaft 126 drives the spray pipe 127 to deflect and extend from the storage bin 125, so that the gas ejected from the spray pipe 127 is sprayed toward the outer surface of the heat exchange bin 2.

[0056] During use, when the internal combustion engine is working and produces exhaust gas, the exhaust gas enters the heat exchange chamber 2 through the exhaust pipe 1. After the exhaust gas enters the heat exchange chamber 2, part of the exhaust gas enters the power generation chamber 72. When the exhaust gas reaches the power generation chamber 72, it contacts the filter plate 4. Under the action of the filter plate 4, the carbon particles in the exhaust gas are separated and attached to the filter plate 4. The separated gas flows to the temperature difference power generation device 3. When the exhaust gas enters the power generation chamber 72, it drives the driving blades 84 to rotate, and synchronously drives the rotating shaft 83 to rotate synchronously. When the rotating shaft 83 rotates, it drives the collecting rod 5 connected to it to rotate on the surface of the filter plate 4, so as to clean the carbon particles on the filter plate 4, and the cleaned carbon particles fall into the collecting chamber 74.

[0057] As the collecting rod 5 rotates, the pushing rods 95 at both ends of the collecting rod 5 are driven to slide in the circular groove 91. During the sliding process of the pushing rod 95 in the circular groove 91, the conical knocking block 93 is pushed to overcome the pressure of the return spring 94 and shrink, and rebounds and knocks the filter plate 4 after losing contact with the pushing rod 95, thereby causing the filter plate 4 to vibrate.

[0058] After the exhaust gas passes through the temperature difference generator, it will enter the air duct 111, and then flow into the Tesla valve 113 from the air duct 111, and finally reach the mixing chamber 121. At this time, the air pressure in the mixing chamber 121 increases, pressing the piston plate 123, causing the piston plate 123 to move. During the displacement of the piston plate 123, the air flow pipe 128 is connected with the connecting groove 122 and the mixing chamber 121, so that the carbon particles in the collecting chamber 74 are mixed with the gas, and then enter the spray pipe 127 through the air flow pipe 128 and the diversion pipe 129, and then are sprayed to the outer surface of the heat exchange chamber 2 through the spray pipe 127. At the same time, because there is a continuous supply of exhaust gas injected into the power generation chamber 72 in the exhaust pipe 1, the air flow in the mixing chamber 121 will not flow back into the power generation chamber 72 through the connecting groove 122, and the carbon particles in the collecting chamber 74 will enter the mixing chamber 121 through the connecting groove 122 under the action of air pressure.

[0059] When the piston plate 123 moves, it drives the power rack 131 to move, and the power rack 131 moves and pushes the rotating gear 134 engaged with it to rotate. The rotation of the rotating gear 134 drives the rotating shaft 133 to rotate synchronously. The rotation of the rotating shaft 133 drives the transmission gear 1 135 to rotate. The rotation of the transmission gear 1 135 drives the transmission gear 2 137 engaged with it to rotate. The rotation of the transmission gear 2 137 drives the worm 136 to rotate. The rotation of the worm 136 drives the worm wheel 138 engaged with it to rotate. The rotation of the worm wheel 138 drives the deflection shaft 126 to rotate. The rotation of the deflection shaft 126 drives the spray pipe 127 to deflect and extend from the storage bin 125, so that the gas ejected from the spray pipe 127 is sprayed toward the outer surface of the heat exchange bin 2.
