[0002] A diesel generator set is a power source that uses a diesel engine as the prime mover to drive a synchronous generator to generate electricity. It is a power generation device that has quick start-up, easy operation and maintenance, low investment, and strong adaptability to the environment.

[0003] A search of CN115788663A discloses a diesel generator set capable of recovering waste heat, comprising a diesel generator mechanism, the diesel generator mechanism comprising a support base, a generator set fixedly mounted on the top of the support base, an exhaust gas exhaust pipe fixedly mounted on one end of the generator set, a heat dissipation mechanism provided on the outer wall of the generator set for heat exchange with the heat generated during operation, an exhaust gas treatment mechanism connected to one end of the exhaust gas exhaust pipe, and a water storage mechanism connected to the bottom of the exhaust gas treatment mechanism. The present invention provides a heat dissipation mechanism on the outer wall of the generator set for heat exchange and heat dissipation, stores the heated water in the heat dissipation pipe in the inner cavity of a hot water tank, and simultaneously treats the high-calorie exhaust gas with the exhaust gas treatment mechanism, reheating the water for subsequent heating use. This improves water utilization, conserves resources, and is more energy-efficient and environmentally friendly.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0046] The exhaust heat recovery unit 200 includes an exhaust gas delivery pipe 201, one end of the exhaust gas delivery pipe 201 is connected to the outlet of the diesel generator 500, and the other end of the exhaust gas delivery pipe 201 is plugged into the temporary storage box 103. A bend pipe 202 is installed at the bottom of the exhaust gas delivery pipe 201, and a turntable cover 2021 is installed at the end of the bend pipe 202. A dispersion cover 204 is movably installed on the turntable cover 2021, and a plurality of pairs of dispersion pipes 2041 are rotatably installed on the dispersion cover 204, and a collection cover 2042 is installed on the plurality of dispersion pipes 2041. The end of the collection cover 2042 is connected to an exhaust gas discharge pipe 2043, and the end of the exhaust gas discharge pipe 2043 is located outside the temporary storage box 103. A stirring plate 205 is installed on each dispersion pipe 2041, and a rotating shaft 203 is installed on the dispersion cover 204. A transmission shaft 2033 is installed at the end of the rotating shaft 203, and a turbine 2032 is installed at the end of the transmission shaft 2033, and the turbine 2032 is placed in the connecting pipe 104; the exhaust gas of the diesel generator can be transported to the exhaust gas delivery pipe, and transported to the turntable cover through the bend at the bottom of the exhaust gas delivery pipe, and the gas is dispersed into several pairs of dispersion pipes through the dispersion cover, and the dispersion pipes can come into contact with the liquid, and thus the contact area of ​​the exhaust gas heat exchange can be increased through multiple pipes, and the connecting pipe is always in the drainage, and thus can drive the turbine to rotate, and the turbine drives the transmission shaft and the rotating shaft to rotate, driving the dispersion pipe to rotate synchronously, and the stirring plate rotates synchronously, which can stir the water body inside the temporary storage box to ensure that the temperature around the water body is uniform, facilitate the heat exchange operation of the exhaust gas, and improve the heat exchange efficiency.

[0047] The oscillation cleaning unit 300 includes a disc 301, on which a protrusion 3011 is installed, and a push rod 302 is slidably provided on the disc 301. The push rod 302 is movable through the inner wall of the exhaust gas delivery pipe 201, and the end of the push rod 302 vertically corresponds to the V-shaped filter plate 3032 installed in the exhaust gas delivery pipe 201, and a collection box 304 is installed on the side wall of the exhaust gas delivery pipe 201 corresponding to the V-shaped filter plate 3032; the rotating shaft can drive the disc to rotate, and when the protrusion contacts the push rod, the push rod is lifted and moved upward, and the push rod knocks and vibrates the V-shaped filter plate, and the small particles on the V-shaped filter plate automatically slide down through the vibration operation, and then fall into the collection box, ensuring that the exhaust gas can flow smoothly.

[0048] The sealing unit 400 includes a mounting cover 401, which is provided with a circular guide rail 402. The circular guide rail 402 is symmetrically provided with an inner groove 4021. A pair of sealing plates 403 are slidably provided at the end of the exhaust pipe 2043. A slide plate 4031 is installed on the pair of sealing plates 403. A side rod 4032 is installed on the slide plate 4031. The side rod 4032 is slidably connected to the circular guide rail 402. An extrusion spring 4043 is clamped on the slide plate 4031. During the rotation of the exhaust pipe, the side rod slides around the circular guide rail. When the side rod moves to the inner groove, the sealing plates are driven to open to both sides by the extrusion spring to facilitate the exhaust gas discharge. When the sealing plates are not opened, the gas in the dispersion pipe will not flow, ensuring that the gas can be stored in the dispersion pipe for a longer period of time, thereby increasing the heat exchange time and allowing the heat in the exhaust gas to be better collected.

[0049] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in a specific embodiment, a water pipe 1012 is installed at the water inlet of the water pump 1013, and the end of the water pipe 1012 is connected to the inner cavity of the water tank 1011. A water inlet pipe 1014 is installed at the water outlet of the water pump 1013, and the end of the water inlet pipe 1014 is connected to the inner cavity of the cover 102. Under the operation of the water pump 1013, the water in the water tank 1011 can be transported along the water pipe 1012 to the water inlet pipe 1014, and then transported to the cover 102 through the water inlet pipe 1014. At this time, the cover 102 is filled with water, and the water at this time can contact the casing of the diesel generator 500, taking away the heat generated during the operation of the diesel generator 500.

[0050] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, further, a water outlet pipe 1022 is installed on the covering cover 102, the end of the water outlet pipe 1022 and the connecting pipe 104 are connected to each other, and a fixing seat 1041 is fixedly installed on the outer wall of the connecting pipe 104, and the fixing seat 1041 is welded to the side wall of the temporary storage box 103, the water inlet height of the water outlet pipe 1022 is higher than the water outlet height of the water inlet pipe 1014, and a cover plate 1021 is installed on the covering cover 102, and the exhaust gas delivery pipe 201 movably passes through the cover plate 1021. The water in the covering cover 102 can eventually flow to the connecting pipe 104 through the outlet pipe 1022, and be transported to the temporary storage box 103 through the connecting pipe 104. Due to the height difference between the outlet pipe 1022 and the inlet pipe 1014, the water injected by the inlet pipe 1014 can enter the interior of the covering cover 102, and the liquid level can slowly rise, and finally the liquid level is higher than the outlet pipe 1022. At this time, the interior of the covering cover 102 is completely filled with water, and then the water can fully contact the diesel generator 500, which can achieve the purpose of recovering the heat from the outer shell.

[0051] Example 2: Based on the above example, the difference between this example and the above example is that: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an observation window 1031 is installed on the top of the temporary storage box 103, and the observation window 1031 can be used to observe the internal heat exchange situation. A heat insulation film is installed on the observation window 1031, and the heat insulation film can reduce heat loss. An inspection door 1032 is installed on one side of the temporary storage box 103, and the inspection door 1032 is interconnected with the inner cavity of the temporary storage box 103. The inspection door 1032 is convenient for later maintenance. A drain outlet 1033 is installed at the bottom of the other side of the temporary storage box 103, and a valve is installed on the drain outlet 1033. The drain outlet 1033 is convenient for the use of heat exchange water.

[0052] like Figure 2 、 Figure 3 and Figure 5 As shown, in a specific embodiment, a feed gate 2011 is bolted to the exhaust gas delivery pipe 201. The feed gate 2011 communicates with the internal chamber of the exhaust gas delivery pipe 201. Two leaking plates 2012 are fixedly mounted inside the exhaust gas delivery pipe 201. The cavity formed by the two leaking plates 2012 and the sidewalls of the exhaust gas delivery pipe 201 is vertically aligned with the feed gate 2011, and activated carbon is placed between the two leaking plates 2012. The feed gate 2011 is opened, and the chamber between the pair of leaking plates 2012 is filled with activated carbon, which is then resealed by the feed gate 2011. During operation, the diesel generator 500 generates a large amount of exhaust gas, which contains a large amount of heat. This heat can be transported along the exhaust gas delivery pipe 201, transferred through the leaking plates 2012, and transferred to the activated carbon. The activated carbon can then adsorb toxic substances, and the treated gas can ultimately be transported through the exhaust gas delivery pipe 201.

[0053] like Figure 5 、 Figure 6 and Figure 9 As shown, further, a plurality of pairs of notches 2051 are provided on the stirring plate 205, a guide seat 2044 is rotatably installed on the exhaust pipe 2043, and the guide seat 2044 is welded to the temporary storage box 103, and a bearing seat 2031 is installed on the temporary storage box 103, and a bearing is clamped inside the bearing seat 2031, and the inner wall of the bearing and the side wall of the rotating shaft 203 are clamped with each other, and the rotating shaft 203 movably passes through the turntable cover 2021. During the normal drainage process of the connecting pipe 104, the high-speed water flow will flush the turbine 2032. At this time, the turbine 2032 will rotate, driving the transmission shaft 2033 and the rotating shaft 203 to rotate inside the bearing seat 2031, and the rotating shaft 203 drives the dispersion cover 204 to rotate as a whole, and finally drives the dispersion pipe 2041, the collecting cover 2042 and the exhaust pipe 2043 to rotate on the guide seat 2044, while the turntable cover as a whole is stationary, and the dispersion cover 204 rotates on the turntable cover, and dynamic sealing technology is used between the dispersion cover and the turntable cover. Dynamic sealing is an existing technology and will not be repeated here. The main purpose is to maintain sealing during movement.

[0054] Example 3: Based on the above embodiment, the difference between this embodiment and the above embodiment is that: Figure 6 、 Figure 7 and Figure 8As shown, a ball is mounted on the bottom of the mandrel 302, and the ball is slidably connected to the sidewall of the disc 301. A synchronizing plate 303 is mounted on the top of the mandrel 302. The synchronizing plate 303 is in a straight line shape, and a knocking plate 3031 is mounted on the synchronizing plate 303. The knocking plate 3031 is vertically aligned with the inclined surface of the V-shaped filter plate 3032, and the bottom of the V-shaped filter plate 3032 and the feed port of the collection box 304 are located on the same plane. A pull plate 3021 is sleeved on the mandrel 302 located in the inner cavity of the exhaust gas conveying pipe 201. A return spring 3022 is sleeved on the mandrel 302. One end of the return spring 3022 is clamped to the pull plate 3021, and the other end of the return spring 3022 is clamped in the inner cavity of the exhaust gas conveying pipe 201. During the rotation of the rotating shaft 203, the disc 301 on the rotating shaft 203 drives the protrusion 3011 to rotate. At this time, the protrusion 3011 will intermittently lift the top rod 302 during the rotation. At this time, the top rod 302 moves upward, driving the synchronous plate 303 and the knocking plate 3031 to push upward. The knocking plate 3031 knocks the bottom of the V-shaped filter plate 3032, thereby vibrating the V-shaped filter plate 3032, and the activated carbon particles on the V-shaped filter plate 3032 will be pushed by the exhaust gas. At this time, the particles have The downward force can push the activated carbon as a whole to slide downward along the inclined surface until it slides to the bottom of the V-shaped filter plate 3032, and the bottom of the V-shaped filter plate 3032 is directly connected to the inlet of the collection box 304, and it is also ensured by vibration combination that the small activated carbon particles filtered by various parts of the V-shaped filter plate 3032 can smoothly slide down the inclined surface and finally fall into the collection box 304, ensuring that the V-shaped filter plate 3032 will not be blocked and the gas in the exhaust gas delivery pipe 201 can be smoothly transported.

[0055] like Figure 5 、 Figure 6 、 Figure 9 and Figure 10As shown, in a specific embodiment, a side bracket 4041 is mounted on the side wall of the exhaust pipe 2043, and a limit rod 404 is mounted on the side bracket 4041. The limit rod 404 movably passes through the slide 4031, and a positioning plate 4042 is mounted on the limit rod 404. A compression spring 4043 is sleeved on the limit rod 404, one end of the compression spring 4043 is clamped on the slide 4031, and the other end of the compression spring 4043 is clamped on the positioning plate 4042. The side wall of the installation cover 401 and the side wall of the temporary storage box 103 are connected to each other. The side wall of the installation cover 401 is mounted on the side wall of the installation cover 401, and the guide cover 4011 is mounted on the guide cover 4011. The external tube 4012 is mounted on the guide cover 4011, and the external tube 4012 and the exhaust pipe 2043 are located on the same centerline. A guide wheel 4033 is rotatably mounted on the side rod 4032, and the guide wheel 4033 is slidably connected to the circular guide rail 402. During the rotation of the exhaust pipe 2043, the exhaust pipe 2043 drives the sealing plate 403 to rotate as a whole. At this time, the side rod 4032 can rotate synchronously, and the side rod 4032 and the guide wheel 4033 slide along the circular guide rail 402. When the side rod 4032 moves to the inner groove 4021, the extrusion spring 4043 pushes the slides 4031 on both sides to start moving to both sides, driving the slides 4031 and the sealing plate 403 to slide along the limit rod 404, and the sealing plate 403 opens the exhaust pipe 2043. When the side rod 4032 and the inner groove 4021 are separated, the sealing plate 403 re-seals the exhaust pipe 2043. By intermittently sealing and exhausting the exhaust pipe 2043, the exhaust gas can be kept in the dispersion pipe 2041 for a longer time, the heat exchange time can be increased, and the waste heat recovery operation can be better completed.

[0056] The implementation principle of a diesel generator set capable of recovering waste heat in this embodiment is as follows:

[0057] The operator first opens the feed door 2011, fills the chamber between a pair of leak plates 2012 with activated carbon, reseals it through the feed door 2011, and fills a certain amount of water into the water tank 1011 and the temporary storage box 103.

[0058] Then the operator turns on the diesel generator 500 and starts the water pump 1013. At this time, under the operation of the water pump 1013, the water in the water tank 1011 can be transported along the water pipe 1012 to the water inlet pipe 1014, and then transported to the cover 102 through the water inlet pipe 1014. At this time, the cover 102 is full of water, and the water at this time can contact the outer casing of the diesel generator 500, taking away the heat generated during the operation of the diesel generator 500.

[0059] During the operation of the diesel generator 500, a large amount of exhaust gas is generated. At this time, the exhaust gas contains a large amount of heat. At this time, the heat can be transported along the exhaust gas delivery pipe 201 and moved to the activated carbon through the leak plate 2012. The activated carbon can adsorb toxic substances, and the treated gas can finally be transported through the exhaust gas delivery pipe 201.

[0060] Since the activated carbon needs to fill the entire cavity between the leak plates, the activated carbon needs to be tightly packed so that the internal cavity can be filled during installation. During this process, the activated carbon may be squeezed, causing the activated carbon to break and be damaged, and small particles of activated carbon can be carried by the exhaust gas. When it moves to the V-shaped filter plate 3032, the filtration operation can be completed, and the treated exhaust gas can eventually move to the turntable cover 2021 through the bend pipe 202, and be transported to the dispersion cover 204 through the turntable cover 2021, and dispersed into multiple dispersion pipes 2041. The multiple dispersion pipes 2041 can increase the heat exchange area, thereby improving the heat exchange quality, and the exhaust inside the dispersion pipe 2041 can be collected through the collecting cover 2042, and finally the discharge operation is completed through the exhaust gas discharge pipe 2043.

[0061] During the normal drainage process of the connecting pipe 104, the high-speed water flow will flush the turbine 2032. At this time, the turbine 2032 will rotate, driving the transmission shaft 2033 and the rotating shaft 203 to rotate inside the bearing seat 2031, and the rotating shaft 203 drives the dispersion cover 204 to rotate as a whole, and finally drives the dispersion pipe 2041, the collecting cover 2042 and the exhaust pipe 2043 to rotate on the guide seat 2044. The stirring operation can be completed by the stirring plate 205 on the dispersion pipe 2041 to ensure that the water inside the temporary storage box 103 can be evenly mixed, and better heat exchange operation with the dispersion pipe 2041 can be performed.

[0062] During the rotation of the rotating shaft 203, the disc 301 on the rotating shaft 203 drives the protrusion 3011 to rotate. At this time, the protrusion 3011 will intermittently lift the push rod 302 during the rotation. At this time, the push rod 302 moves upward, driving the synchronization plate 303 and the knocking plate 3031 to push upward. The knocking plate 3031 knocks on the bottom of the V-shaped filter plate 3032, and then vibrates the V-shaped filter plate 3032. The small activated carbon particles filtered on the surface of the V-shaped filter plate 3032 can slide down through the inclined surface and eventually fall into the collection box 304. At a later stage, the inspection door can be removed and the collection box 304 can be replaced as a whole. When the particles fall into the collection box, it can ensure that the V-shaped filter plate 3032 will not be blocked, and the gas in the exhaust gas delivery pipe 201 can be smoothly transported.

[0063] During the rotation of the exhaust pipe 2043, the exhaust pipe 2043 drives the sealing plate 403 to rotate as a whole. At this time, the side rod 4032 can rotate synchronously, and the side rod 4032 and the guide wheel 4033 slide along the circular guide rail 402. When the side rod 4032 moves to the inner groove 4021, the extrusion spring 4043 pushes the slides 4031 on both sides to start moving to both sides, driving the slides 4031 and the sealing plate 403 to slide along the limit rod 404, and the sealing plate 403 opens the exhaust pipe 2043. When the side rod 4032 and the inner groove 4021 are separated, the sealing plate 403 re-seals the exhaust pipe 2043. By intermittently sealing and exhausting the exhaust pipe 2043, the exhaust gas can be kept in the dispersion pipe 2041 for a longer time, the heat exchange time can be increased, and the waste heat recovery operation can be better completed.

[0064] When the water pump 1013 stops moving, the sealing plate 403 is in two states: sealed and open. When the sealing plate 403 is in the open state, the exhaust gas can flow smoothly. When the sealing plate 403 is in the sealed state, the side rod 4032 is located on the arcuate side of the inner groove 4021 (the arcuate side is Figure 10 The inclined surface at position a in the middle) is pushed by the extrusion spring 4043 to push the side rod 4032 to move outward, so that the side rod 4032 can slide along the inclined position to the bottom of the inner groove 4021, and finally the sealing plate 403 can be opened (the sealing plate 403 can also be manually reset without affecting the normal emission of exhaust gas). Therefore, when the water pump 1013 stops working, the sealing plate 403 is open and will not affect the normal operation of the diesel generator.
