Description

Technical Field

[0001] The invention belongs to the technical field of generator exhaust components, and in particular relates to a smoke-eliminating and silent exhaust component for a diesel generator set. Background Art

[0002] A diesel generator set is a small-scale power generation equipment. It uses a diesel engine as the prime mover to drive a synchronous generator to generate electricity. It can be used for daily power generation and emergency power generation in various households, offices, large, medium and small enterprises. When a diesel generator set is running, it needs to burn diesel and discharge smoke through the exhaust pipe. The smoke discharged by the diesel generator set is generally discharged directly without treatment, which is harmful to the environment. The temperature of the smoke is relatively high. Directly discharged into the air will increase the room temperature, and the high-temperature smoke will transfer heat to the exhaust pipe. If the staff accidentally touches the exhaust pipe, they will be burned. The smoke flows in the exhaust pipe, resonates, and forms a shock wave in the exhaust pipe. Finally, an explosion sound is emitted at the moment of discharge from the exhaust pipe. The noise is relatively large during operation. At the same time, the smoke dust in the smoke will be adsorbed on the inside of the exhaust pipe. After long-term use, the wall thickness of the exhaust pipe will be thickened, making the exhaust pipe smoke unsmooth.

[0003] The existing Chinese patent document with publication number CN117469021B proposes to solve the above-mentioned problem by connecting a soot cleaning component through a flange at the exhaust end of the smoke exhaust pipe. However, the above-mentioned soot cleaning component mainly relies on the fact that when the smoke enters the auxiliary smoke exhaust pipe, the impeller can be driven to rotate under the action of the gas flow rate, so that the rotating rod connected to the impeller can drive the scraper rod and the cleaning brush installed at one end of the T-shaped fixed rod to rotate inside the auxiliary smoke exhaust pipe, and the smoke attached to the inner wall of the auxiliary smoke exhaust pipe is scraped off to clean the smoke. However, there will be a problem that a part of the smoke discharged along with the gas contains carbon particles that cannot be treated. The carbon particles will enter the air with the smoke and cause air pollution.

[0004] Therefore, the present invention proposes a smoke-eliminating and silent exhaust component for a diesel generator set to solve the problem in the prior art that a soot cleaning component is connected to the exhaust end of the smoke exhaust pipe through a flange, which causes a part of the smoke discharged along with the gas to contain carbon particles that cannot be treated and will enter the air with the smoke, causing air pollution. The carbon particle filter component and the exhaust gas circulation pipeline are designed to be combined to reintroduce the concentrated exhaust gas into the intake system for secondary combustion, which not only reduces the exhaust smoke but also improves the utilization rate of fuel.

[0037] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0038] Example 1, please refer to Figures 1 to 18The present invention provides a technical solution: comprising a diesel generator housing 1, a diesel generator body 11 is arranged inside the diesel generator housing 1, an auxiliary exhaust device 12 is arranged outside the diesel generator body 11, an air inlet of the diesel generator body 11 is fixedly installed with an air inlet pipe 13 through a flange, a filter T-type pipe 4 is fixedly installed at the exhaust port of the diesel generator body 11 through a flange, an exhaust pipe 3 is fixedly installed at one end of the filter T-type pipe 4 through a flange, the lower end of the exhaust pipe 3 is fixedly connected to the input pipe end of the auxiliary exhaust device 12, an exhaust cooling pipe 5 is arranged outside the exhaust pipe 3, and a soundproof cover is arranged outside the filter T-type pipe 4 2. An exhaust branch pipe 41 is fixedly installed on the upper end of the filter T-tube 4 through a flange, one end of the exhaust branch pipe 41 is fixedly connected to the middle of the intake pipe 13, a valve seat 1 42 is arranged on the side of the filter T-tube 4 close to the exhaust pipe 3, a valve seat 2 43 is arranged above the filter T-tube 4, a spherical valve core 1 421 is rotatably installed inside the valve seat 1 42, a spherical valve core 2 431 is rotatably installed inside the valve seat 2 43, a bevel gear 1 422 is fixedly installed on the upper end of the rotating shaft of the spherical valve core 1 421, a bevel gear 2 432 is fixedly installed on one end of the rotating shaft of the spherical valve core 2 431, and the bevel gear 2 432 and the outer surface of the bevel gear 1 422 are meshed with each other;

[0039] In this embodiment, the diesel generator housing 1 is installed to protect the diesel generator body 11, and the auxiliary exhaust equipment 12 plays a role in assisting the diesel generator body 11 to exhaust. The intake pipe 13 cooperates with the diesel generator body 11 to take in air inside the combustion chamber. The filter T-tube 4 is installed at the exhaust pipe of the diesel generator body 11. The gas discharged from the diesel generator body 11 contains unburned carbon particles to form smoke and enter the filter T-tube 4. First, the ball valve core 1 421 is in an open state, and the ball valve core 2 431 is in a closed state, so that the gas is filtered by the carbon smoke filter cover 47 and then discharged through the exhaust pipe 3. The carbon smoke filter cover 47 inside the filter T-tube 4 filters and aggregates the carbon particles, captures most of the solid particles during the filtering process, and plays a role in reducing the smoke. After filtering for a period of time, the concentration of carbon particles increases because the bevel gear 1 42 2 is meshed with the spherical valve core 2 431, and when the motor 45 drives the spherical valve core 1 421 to rotate inside the valve seat 1 42, the spherical valve core 2 431 will be driven to rotate inside the spherical valve core 2 431. At this time, the spherical valve core 1 421 is closed and the spherical valve core 2 431 is opened, and the front end of the filtering T-tube 4 is closed, so that the accumulated carbon particles are accompanied by the unfiltered flue gas upward through the spherical valve core 2 431 into the exhaust branch pipe 41, and are transported into the intake pipe 13 and enter the combustion chamber to participate in the combustion, thereby reducing the oxygen concentration and combustion temperature in the combustion chamber, reducing the generation of nitrogen oxides, and helping to reduce black smoke emissions, not only reducing exhaust smoke but also improving fuel utilization, solving the problem in the prior art that a part of the flue gas discharged with the gas contains carbon particles that cannot be processed and will enter the air with the flue gas, causing air pollution.

[0040] Example 2, please refer to Figures 1 to 18 On the basis of the first embodiment, in order to increase the sealing performance of the spherical valve core 1 421 and the spherical valve core 2 431 to the gas seal, the present embodiment further proposes that the valve seat 1 42 and the valve seat 2 43 are respectively provided with a valve core sealing cover 48 adapted to the spherical valve core 1 421 and the spherical valve core 2 431, and the inner side wall of the valve core sealing cover 48 is fixedly installed with an elastic sealing convex piece 481;

[0041] In this embodiment, the valve core sealing cover 48 is wrapped around the outside of the spherical valve core 1 421 and the spherical valve core 2 431, and the sealing between the spherical valve core 1 421 and the valve seat 1 42, and between the spherical valve core 2 431 and the valve seat 1 42 is distributed. When the spherical valve core 1 421 or the spherical valve core 2 431 is rotated to open, the elastic sealing protrusion 481 is squeezed. When the spherical valve core 1 421 or the spherical valve core 2 431 is rotated to close, the elastic sealing protrusion 481 will pop up to block the valve core through hole of the spherical valve core 2 431 or the spherical valve core 1 421, thereby further improving the sealing of the valve seat 2 43 and the valve seat 1 42.

[0042] Example 3, please refer to Figures 1 to 18 On the basis of the second embodiment, in order to make it easier to shake off the carbon particles after filtering and gathering by the soot filter cover 47, the present embodiment further proposes that an auxiliary guide core 46 is rotatably installed below the inner wall of the middle part of the filter T-tube 4, and an auxiliary sealing plate 461 is symmetrically hingedly installed on the outer side of the auxiliary guide core 46. The outer side of the auxiliary sealing plate 461 contacts the inner surface of the filter T-tube 4, and a motor fixing box 44 is arranged below the filter T-tube 4. The side surface of the motor fixing box 44 is fixedly connected to the lower end of the soundproof cover 2, and a gear 423 is fixedly installed on the outer surface below the rotating shaft of the spherical valve core 1 421, and a gear 2 462 is fixedly installed on the outer surface below the rotating shaft of the auxiliary guide core 46. The outer surface of the gear 1 423 is in contact with the gear The outer surfaces of the gear 1 423 mesh with each other, the gear 1 423 and the gear 2 462 are arranged inside the motor fixing box 44, a motor 45 is fixedly installed on one side of the lower surface of the motor fixing box 44, the output shaft of the motor 45 is fixedly connected to the bottom end of the rotating shaft of the spherical valve core 1 421, a carbon smoke filter cover 47 is arranged between the spherical valve core 1 421 and the auxiliary guide core 46, a support frame 471 is arranged on the side of the carbon smoke filter cover 47 close to the spherical valve core 1 421, the outer surfaces of the frame of the carbon smoke filter cover 47 and the support frame 471 are fixedly connected to the inner surface of the filter T-tube 4, a support ball 472 is fixedly installed in the middle of the support frame 471, and the outer surface of the support ball 472 is in contact with the side surface of the carbon smoke filter cover 47;

[0043] In this embodiment, the auxiliary guide core 46 is spindle-shaped. When the spray head 521 is in a closed state, the two ends of the auxiliary guide core 46 are distributed in a direction perpendicular to the air flow, and the auxiliary sealing plate 461 is naturally closed. During the closing process of the auxiliary sealing plate 461, the arc-shaped protrusions at both ends will hit the carbon smoke filter cover 47. The support frame 471 and the support ball 472 support the carbon smoke filter cover 47 so that the carbon smoke filter cover 47 is arc-shaped and protrudes toward the air inlet end of the filter T-tube 4, thereby increasing the filtering area. When the carbon smoke filter cover 47 is hit by the auxiliary sealing plate 461, a vibration is first generated to shake off the filtered and accumulated carbon particles, and then After the support ball 472 is squeezed, the carbon smoke filter cover 47 is reset to generate secondary vibration, and the carbon particles are shaken off by the secondary vibration. Because the gear 2 462 is meshed with the spray branch pipe 523, when the motor 45 drives the spherical valve core 1 421 to rotate and open, the auxiliary guide core 46 rotates accordingly. At this time, the two ends of the auxiliary guide core 46 are distributed parallel to the airflow direction, and the auxiliary sealing plate 461 is squeezed by the inner wall of the filtering T-tube 4 and flipped and unfolded. At this time, the auxiliary sealing plate 461 cooperates with the auxiliary guide core 46 to also have a certain guiding effect on the airflow, and the carbon particles carried by the gas collide and disperse, making it easier for the carbon smoke filter cover 47 to filter out the carbon particles.

[0044] Example 4, please refer to Figures 1 to 18On the basis of the third embodiment, in order to reduce the noise of the air flow inside the filtering T-tube 4, the present embodiment further proposes that the top of the soundproof cover 2 is fixedly connected to the top of the inner surface of the diesel generator housing 1 by bolts, the top of the soundproof cover 2 is provided with a through groove adapted to the exhaust branch pipe 41, the outer wall of the soundproof cover 2 is provided with a heat dissipation groove 21, and heat dissipation fins 22 are arranged on both sides of the heat dissipation groove 21. The heat dissipation fins 22 are fixedly installed obliquely on the outer surface of the soundproof cover 2, and the inner surface of the heat dissipation fins 22 is fixedly installed with a porous sound absorbing panel 221.

[0045] In this embodiment, the soundproof cover 2 uses sound insulation and noise reduction materials, the heat dissipation groove 21 is convenient for filtering the T-tube 4 for heat dissipation, the heat dissipation fins 22 accelerate the transfer of heat to the air, improve the heat dissipation efficiency of the heat dissipation groove 21, and the sound absorption holes of the porous sound-absorbing plate 221 absorb part of the noise, thereby increasing the sound insulation effect of the soundproof cover 2.

[0046] Example 5, please refer to Figures 1 to 18 On the basis of the fourth embodiment, in order to make the filter T-tube 4 contact with the inner wall of the soundproof cover 2 to avoid vibration and noise, the present embodiment further proposes that the inner surface of the soundproof cover 2 is provided with a heat dissipation fin 22 adapted to the filter T-tube 4, and a porous sound-absorbing plate 221 is fixedly installed between the outer surface of the heat dissipation fin 22 and the inner surface of the soundproof cover 2. The heat dissipation fin 22 is symmetrically sleeved on the outer surface of the filter T-tube 4. The inner surface of the soundproof cover 2 is also fixedly installed with a tube fixed heat dissipation half circle 23. Two groups of tube fixed heat dissipation half circles 23 are provided. One side of the two groups of tube fixed heat dissipation half circles 23 is respectively in contact with the outer surface of the valve seat 1 42 and the valve seat 2 43. A shock-absorbing spring 1 231 is provided in the middle of the tube fixed heat dissipation half circle 23;

[0047] In this embodiment, the valve seat shock-absorbing support frame 24 supports the outer walls of the valve seat 1 42 and the valve seat 2 43, and the shock-absorbing spring 241 can buffer the vibration of the valve seat 1 42 and the valve seat 2 43 caused by the airflow. The tube fixed heat dissipation half circle 23 supports the outer side of the filter T-tube 4, and the shock-absorbing spring 1 231 buffers the vibration caused by the airflow inside the filter T-tube 4, thereby preventing the filter T-tube 4 from vibrating and generating noise due to contact with the inner wall of the sound insulation cover 2.

[0048] Example 6: Please refer to Figures 1 to 18On the basis of the fourth embodiment, in order to cool the outside of the exhaust pipe 3, the present embodiment further proposes that the exhaust cooling pipe 5 is sleeved on the outer surface of the exhaust pipe 3, a cover 51 is provided on the top of the exhaust cooling pipe 5, a spray ring pipe 52 is clamped and installed on the upper part of the inner part of the cover 51, a spray head 521 is provided in the middle of one side of the spray ring pipe 52, a transparent water storage bottle 522 is provided at one end of the spray ring pipe 52, arc-shaped elastic buckles 531 are evenly distributed on the inner wall of the exhaust cooling pipe 5, a filter cotton core 53 is clamped and installed on the outer side of the arc-shaped elastic buckle 531, a slot matching the filter cotton core 53 is provided on the side wall of the exhaust pipe 3, an inner sealing ring gasket 31 matching the filter cotton core 53 is fixedly installed on the inner surface of the exhaust pipe 3, a spray branch pipe 523 is fixedly installed on the lower surface of the spray ring pipe 52, and the discharge hole of the spray branch pipe 523 is in contact with the side surface of the filter cotton core 53;

[0049] In this embodiment, the exhaust cooling pipe 5 is surrounded by the outside of the exhaust pipe 3, and the cooling water stored in the transparent water storage bottle 522 is sprayed through the spray head 521. The spray is circulated through the spray ring pipe 52 and the spray branch pipe 523 to soak the filter cotton core 53. The filter cotton core 53 is stuck in the inner wall of the exhaust pipe 3. After the air flow is filtered, it carries a small amount of smoke and dust to adsorb and reduce dust. At the same time, the water evaporates and absorbs heat, which can cool the exhaust pipe 3. The arc-shaped elastic buckle 531 fixes the filter cotton core 53. At the same time, the spray branch pipe 523 will squeeze the filter cotton core 53 when inserted, so that the filter cotton core 53 and the inner wall of the exhaust pipe 3 are more tightly filled. The inner sealing ring gasket 31 seals the area around the slot of the exhaust pipe 3. The inner sealing ring gasket 31 has a triangular guide strip, which can play a role in guiding and rectifying the flow to avoid the generation of eddy currents and generating greater noise. The filter cotton core 53 also has the effect of sound absorption and noise reduction.

[0050] Example 7, please refer to Figures 1 to 18 Based on the fifth embodiment, this embodiment further proposes a method for using a smoke and noise elimination exhaust assembly of a diesel generator set, comprising the following steps:

[0051] Step 1, smoke filtering, the air intake pipe 13 cooperates with the diesel generator set body 11 to take in air inside the combustion chamber, the auxiliary exhaust equipment 12 assists the diesel generator set body 11 to exhaust, the gas discharged from the diesel generator set body 11 contains unburned carbon particles to form smoke and enter the filter T-tube 4, firstly, the ball valve core 1 421 is in an open state, and the ball valve core 2 431 is in a closed state, so that the gas is filtered by the carbon smoke filter cover 47 and then discharged through the exhaust pipe 3, the carbon smoke filter cover 47 inside the filter T-tube 4 filters and aggregates the carbon particles, and captures most of the solid particles during the filtering process to reduce smoke;

[0052] Step two, the filtered gas is discharged, and the cooling water stored in the transparent water storage bottle 522 generates spray through the spray head 521. The spray circulates through the spray ring tube 52 and the spray branch pipe 523 to soak the filter cotton core 53. The filter cotton core 53 is stuck in the inner wall of the exhaust pipe 3. After the air flow is filtered, a small amount of smoke and dust is carried to absorb and reduce dust. At the same time, the evaporation of water absorbs heat, which can cool the exhaust pipe 3, thereby reducing the temperature of the exhaust gas from the exhaust pipe 3 and avoiding affecting the auxiliary exhaust equipment 12.

[0053] Step three, exhaust gas circulation, after filtering for a period of time, the motor 45 drives the ball valve core 1 421 to rotate and close, the ball valve core 2 431 to rotate and open, and the front end of the filtering T-tube 4 is closed, so that the accumulated carbon particles are accompanied by the unfiltered smoke upward through the ball valve core 2 431 into the exhaust branch pipe 41, and are transported into the intake pipe 13, and enter the combustion chamber to participate in secondary combustion. Then, the motor 45 drives the ball valve core 1 421 to rotate in the opposite direction to open, and the ball valve core 2 431 to rotate and close, and repeat the smoke filtering steps. It is worth noting that the length of the filtering time depends on the specific situation.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
