Description

Technical Field

[0001] The present invention relates to the technical field of generator exhaust, and in particular to an exhaust structure for a containerized diesel generator set. Background Art

[0002] The exhaust device of the containerized diesel generator set is one of its important components, which is mainly composed of exhaust manifold, bellows, muffler, exhaust gas treatment system, silencer, etc. The muffler is mainly used to reduce exhaust noise. It reduces the noise level by changing the direction of airflow, increasing airflow resistance, etc.

[0003] Since diesel produces byproducts such as carbon dioxide and water vapor when it burns in the engine, when the exhaust gas enters the muffler through the exhaust system, as the exhaust gas temperature drops, the water vapor will condense into liquid water and accumulate inside the muffler. Long-term water accumulation will cause metal parts to rust and corrode, shorten the service life of the muffler, and may cause structural damage. The accumulated water occupies part of the space of the muffler, increasing the resistance to exhaust flow, which will have a negative impact on engine performance. Therefore, it is necessary to take measures to reduce the accumulation of water inside the muffler.

[0004] In existing technology, accumulated water is often drained by opening a drain hole at the bottom of the muffler. However, this requires periodic shutdown of the generator set, impacting power generation efficiency. Furthermore, if the drain hole is too small, it is prone to clogging, while if it is too large, it may damage the internal acoustic structure of the muffler, resulting in reduced noise reduction performance. To address the above technical issues, the present invention proposes an exhaust structure for containerized diesel generator sets. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an exhaust structure for a containerized diesel generator set to solve the shortcomings of the above-mentioned prior art, including a bellows and a muffler, and a water absorption unit is installed between the bellows and the muffler through a connecting unit.

Both the storage ring 1 and the storage ring 2 are provided with a semi-annular storage groove for storing water absorption material.

[0007] The inner sides of the storage ring 1 and the storage ring 2 are both provided with two symmetrically distributed feeding grooves, which are connected to the corresponding storage grooves. The inner side of the storage ring 1 is also provided with a connecting groove for connecting the storage ring 2 and the fixed cylinder.

[0008] Two concentrically distributed annular grooves are provided inside the fixed cylinder, and the parts corresponding to the annular grooves at the left and right ends of the fixed cylinder are hollow structures, and the parts of the fixed cylinder without the annular grooves are solid structures.

[0015] Preferably, the storage ring 1 and the storage ring 2 are symmetrically provided with arc grooves connected to the storage trough, a connecting spring is installed in the arc groove, and a pushing block is installed at the end of the connecting spring away from the arc groove. The pushing block is located in the storage trough and is tightly attached to the inner wall of the storage trough.

[0016] Preferably, when the connecting spring is extended to the limit position, the positions of the two pushing blocks corresponding to the same storage trough correspond one-to-one to the positions of the two corresponding feeding troughs, and the two feeding troughs are located between the two pushing blocks.

[0017] Preferably, the positioning ring is further provided with two positioning holes three, the positioning holes three are communicated with the guide grooves corresponding to the positioning holes one, and the diameter of the positioning holes three is greater than the width of the guide grooves.

[0018] There are two communicating grooves symmetrically arranged. When the communicating groove is connected to the second storage ring through the corresponding feeding groove, the communicating groove is not connected to the discharge groove.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] See Figure 1 An exhaust structure for a containerized diesel generator set includes a bellows 1 and a muffler 2. A water absorption unit 4 for reducing moisture entering the muffler 2 is installed between the bellows 1 and the muffler 2 through a connecting unit 3.

[0040] For details, see Figure 1 and Figure 3The connecting unit 3 includes two hoops 31 arranged opposite each other in front and back. The two hoops 31 are fixedly connected by bolts. The hoops 31 have a U-shaped cross-section, and a rubber sealing ring 32 is provided between the inner wall of the hoops 31 and the flange of the connecting end to enhance the sealing after the connection. Of course, flange connection or other existing connection methods can also be used for connection.

[0041] See Figure 1 、 Figure 2 and Figure 3 The water absorption unit 4 includes a fixed cylinder 41, a storage ring 1 42 rotatably mounted on the outer wall of the fixed cylinder 41, and a storage ring 2 43 rotatably mounted on the outer wall of the storage ring 1 42. The storage ring 1 42 and the storage ring 2 43 are both provided with a semi-annular storage groove 44 inside, and the storage groove 44 is used to store water absorption material; the water absorption material can be selected from high-temperature resistant water absorption particles such as activated alumina particles or ceramic-based particles.

[0042] To facilitate the connection, Figure 1 and Figure 2 As shown, connecting ends are provided at both left and right ends of the fixed cylinder 41, the bellows 1 and the muffler 2. The length of the connecting end can be selected according to actual needs. The connecting end is integrally formed with a flange at one end away from the corresponding fixed cylinder 41, the muffler 2 or the bellows 1. In addition, the solid part of the fixed cylinder 41 is provided with a plurality of through holes distributed in a honeycomb shape to reduce the exhaust back pressure.

[0043] See Figure 3 and Figure 4 Two symmetrically distributed feeding grooves 45 are provided on the inner sides of the storage ring 1 42 and the storage ring 2 43. The feeding grooves 45 are connected with the corresponding storage grooves 44 to transport the water-absorbing material. A connecting groove 46 for connecting the storage ring 2 43 and the fixed cylinder 41 is also provided on the inner side of the storage ring 1 42, so that the water-absorbing material can be transported between the storage ring 2 43 and the fixed cylinder 41.

[0044] See Figure 4 Two concentrically distributed annular grooves 411 are provided inside the fixed cylinder 41, and the left and right ends of the fixed cylinder 41 corresponding to the annular grooves 411 are hollow structures (not shown in the figure) so that the exhaust gas can enter the annular grooves 411 for water absorption treatment. The part of the fixed cylinder 41 without the annular grooves 411 is a solid structure.

[0045] See Figure 3 and Figure 4The upper end of the fixed cylinder 41 is provided with a feeding groove 412 connected to the outer annular groove 411. The water-absorbing material can enter the corresponding annular groove 411 through the feeding groove 412, so that the water-absorbing material can absorb water from the exhaust gas entering the annular groove 411. The lower end of the fixed cylinder 41 is provided with a discharging groove 413 connected to the outer annular groove 411. The water-absorbing material in the fixed cylinder 41 can be discharged into the corresponding storage groove 44 through the discharging groove 413 to realize the renewal or replacement of the water-absorbing material. The solid part of the fixed cylinder 41 is provided with a conveying groove 414 for connecting the two annular grooves 411. The water-absorbing material can enter the inner annular groove 411 from the outer annular groove 411 through the conveying groove 414, so that a sufficient amount of water-absorbing material is filled in the fixed cylinder 41.

[0046] When the feed trough 412 corresponds to the position of the feed trough 45 on the storage ring 42, the storage ring 42 is located directly above the fixed cylinder 41, and the water-absorbing material in the storage trough 44 of the storage ring 42 enters the outer annular groove 411 through the feed trough 45 and the feed trough 412, and enters the inner annular groove 411 through the transfer groove 414. At this time, the water vapor in the passing exhaust gas can be absorbed by the water-absorbing material in the fixed cylinder 41, thereby reducing the moisture entering the muffler 2, and thereby reducing the water accumulation in the muffler 2.

[0047] In order to avoid the situation that the water-absorbing material cannot be completely discharged from the fixed cylinder 41, the present invention makes the following design on the structure of the discharge trough 413: Figure 4 As shown, the discharge trough 413 is composed of two trumpet mouths symmetrically distributed front and back and a strip groove connected at the lower end of the trumpet mouth. The side of the two trumpet mouths close to each other is a slope structure to guide the water-absorbing material into the strip groove, and then enter the corresponding feed trough 45 or connecting groove 46 from the strip groove.

[0048] See Figure 3 and Figure 4 The storage ring 1 42 and the storage ring 2 43 are symmetrically provided with arc grooves connected to the storage groove 44, and a connecting spring is installed in the arc groove ( Figure 4 The connecting spring in the material storage trough is in a compressed state), a pushing block 47 is installed at the end of the connecting spring away from the arc groove. The pushing block 47 is located in the material storage trough 44 and is in close contact with the inner wall of the material storage trough 44. When there is water-absorbing material in the material storage trough 44, the pushing block 47 is driven by the connecting spring to push the water-absorbing material, so that the water-absorbing material moves toward the feeding trough 45.

[0049] In the process of feeding the water-absorbing material in the corresponding storage trough 44 into the fixed cylinder 41, the pushing block 47 is driven by the connecting spring to push the water-absorbing material toward the feeding trough 45, ensuring that all the water-absorbing material in the storage trough 44 can eventually enter the interior of the fixed cylinder 41, thereby ensuring the water absorption effect.

[0050] When all the absorbent materials in the storage trough 44 are fed into the fixed cylinder 41, when the connecting spring is extended to the limit position, the positions of the two pushing blocks 47 corresponding to the same storage trough 44 correspond to the positions of the two corresponding feeding troughs 45, and the two feeding troughs 45 are located between the two pushing blocks 47, so as to prevent the pushing blocks 47 from obstructing the absorbent materials falling from the feeding trough 45 when the absorbent materials return from the fixed cylinder 41 to the storage trough 44 (such as Figure 6 shown).

[0051] See Figure 1 and Figure 2 The present invention further includes a switching unit 5 for switching the positions of the material storage ring 1 42 and the material storage ring 2 43 to replace the water-absorbing material in the fixed cylinder 41.

[0052] After the water-absorbing material in the fixed cylinder 41 has been used for a certain period of time, its water-absorbing effect is reduced. At this time, the storage ring 42 can be rotated 180 degrees through the switching unit 5, so that the storage ring 42 is located below the fixed cylinder 41 and the feeding trough 45 on it is connected to the discharge trough 413. At this time, the water-absorbing material in the fixed cylinder 41 will return to the storage trough 44 of the storage ring 42 through the discharge trough 413 and the feeding trough 45.

[0053] Next, the storage ring 2 43 is adjusted in the opposite direction by a certain angle through the switching unit 5, so that the connecting groove 46 is connected to the feeding groove 412, and the storage ring 2 43 originally located directly below the fixed cylinder 41 is rotated 180 degrees through the switching unit 5, so that it is rotated to directly above the fixed cylinder 41 and its feeding groove 45 is connected to the connecting groove 46. At this time, the water-absorbing material in the storage ring 2 43 can enter the interior of the fixed cylinder 41 through the feeding groove 45, the connecting groove 46 and the feeding groove 412 to continue to absorb water from the exhaust gas.

[0054] It should be noted that the portion of the side wall of the storage ring 1 42 and the storage ring 2 43 corresponding to the storage groove 44 can be set as a hollow structure to ventilate and dry the water-absorbing material inside, so that the water-absorbing material can be reused.

[0055] Since the service life of the water-absorbing material is limited, in order to ensure the water-absorbing effect, it needs to be replaced regularly. Figure 3 As shown, the side walls of the material storage ring 1 42 and the material storage ring 2 43 are both provided with a discharge port 48, which is connected to the corresponding material storage trough 44. The side of the material storage trough 44 away from the axis of the fixed cylinder 41 is provided with an inclined surface inclined toward the discharge port 48 to guide the water-absorbing material in the material storage trough 44 to the discharge port 48, so that the water-absorbing material can be replaced regularly. When the water-absorbing material does not need to be replaced, the drainage port is blocked by a sealing plug.

[0056] See Figure 2 and Figure 5 The switching unit 5 includes a positioning ring 51 fixedly mounted on one of the connection ends of the fixed cylinder 41, and the positioning ring 51 is provided with two centrally symmetrically distributed positioning holes 52 and two centrally symmetrically distributed positioning holes 53 located between the two positioning holes 52.

[0057] A positioning rod 1 54 is installed on the side wall of the storage ring 1 42 and is inserted into the corresponding positioning hole 1 53. The position of the storage ring 1 42 is limited by the cooperation between the positioning hole 1 53 and the positioning rod 1 54; a positioning rod 2 55 is installed on the side wall of the storage ring 2 43 and is inserted into the corresponding positioning hole 2 52 for sliding left and right. The position of the storage ring 2 43 is limited by the cooperation between the positioning hole 2 52 and the positioning rod 2 55.

[0058] When the positioning rod 1 54 is inserted into the upper positioning hole 1 53, the storage ring 1 42 is located directly above the fixed cylinder 41; when the positioning rod 1 54 is inserted into the lower positioning hole 1 53, the storage ring 1 42 is located directly below the fixed cylinder 41. Similarly, when the positioning rod 2 55 is inserted into the upper positioning hole 2 52, the storage ring 2 43 is located directly above the fixed cylinder 41; when the positioning rod 2 55 is inserted into the lower positioning hole 2 52, the storage ring 2 43 is located directly below the fixed cylinder 41.

[0059] See Figure 2 and Figure 5 Both positioning rod 1 54 and positioning rod 2 55 consist of a fixed rod 5a and a telescopic rod 5b slidably connected to fixed rod 5a via a spring (not shown). Telescopic rod 5b is composed of two coaxial cylindrical segments of different diameters. An arc-shaped guide groove 56 is defined between the two positioning holes 1 53 and between the two positioning holes 2 52. The diameter of the smaller cylindrical segment is smaller than the width of the guide groove 56, which is in turn smaller than the diameter of both positioning holes 1 53 and 2 52.

[0060] When it is necessary to switch the position of the material storage ring 1 42 and the material storage ring 2 43, first pull the telescopic rod 5b of the positioning rod 1 54 or the positioning rod 2 55, so that the cylindrical section with the larger diameter of the telescopic rod 5b moves out of the positioning hole 1 53 or the positioning hole 2 52, and the cylindrical section with the smaller diameter enters the positioning hole 1 53 or the positioning hole 2 52. At this time, the cylindrical section can be pulled to slide in the guide groove 56. After moving to the designated position, the telescopic rod 5b is pushed in the opposite direction so that the cylindrical section with the larger diameter is re-engaged in the corresponding positioning hole 1 53 or the positioning hole 2 52. The switching action of the material storage ring 1 42 and the material storage ring 2 43 can be completed quickly to ensure the water absorption effect.

[0061] See Figure 5The positioning ring 51 further has two positioning holes 57 3 , which are connected to the guide groove 56 corresponding to the positioning hole 1 53 , and the diameter of the positioning hole 57 is greater than the width of the guide groove 56 .

[0062] See Figure 4 The two communicating grooves 46 are symmetrically provided. When the communicating groove 46 is connected with the storage ring 2 43 through the feeding groove 45 on the storage ring 2 43 (as shown in FIG. Figure 8 As shown in FIG), the feeding groove 45 on the storage ring 42 is not connected to the discharge groove 413. At this time, the position of the positioning rod 54 corresponds to the positioning hole 3 57; when the connecting groove 46 is connected to the discharge groove 413, the feeding groove 45 on the storage ring 42 is not connected to the feeding groove 412 (as shown in FIG). Figure 10 As shown), at this time, the position of the positioning rod 1 54 corresponds to another positioning hole 3 57 to ensure that when the water-absorbing material inside the fixed cylinder 41 is replaced, the water-absorbing materials in the storage ring 2 43 and the storage ring 1 42 will not be mixed together.

[0063] During specific use, the first storage ring 42 and the second storage ring 43 are rotated successively to the top of the fixed cylinder 41 , and the water-absorbing material is fed into the corresponding storage trough 44 through the corresponding discharge port 48 .

[0064] When the water-absorbing material in the storage ring 42 needs to be fed into the fixed cylinder 41, the storage ring 42 is positioned just above the fixed cylinder 41 (such as Figure 7 As shown), at this time, the feeding groove 45 on the storage ring 42 corresponds to the position of the feeding groove 412, and the water-absorbing material in the storage ring 42 enters the inner and outer annular grooves 411 through the feeding groove 45 and the feeding groove 412.

[0065] When it is necessary to discharge the water-absorbing material in the fixed cylinder 41 into the storage ring 1 42, the storage ring 1 42 is positioned just below the fixed cylinder 41 (such as Figure 9 As shown), at this time, the feeding groove 45 on the storage ring 42 corresponds to the position of the discharge groove 413, and the water-absorbing material in the annular groove 411 enters the storage groove 44 of the storage ring 42 through the discharge groove 413 and the feeding groove 45.

[0066] When the absorbent material in the second storage ring 43 needs to be fed into the fixed cylinder 41, the second storage ring 43 is first positioned to the top of the fixed cylinder 41 by the cooperation of the second positioning hole 52 and the second positioning rod 55, and then the first storage ring 42 is positioned to the position where the connecting groove 46 is connected to the feeding groove 45 on the second storage ring 43 by the cooperation of the third positioning hole 57 and the first positioning rod 54. Figure 8As shown), at this time, the connecting groove 46 is also connected to the feeding groove 412, and the water-absorbing material in the storage ring 43 enters the inner and outer annular grooves 411 through the feeding groove 45, the connecting groove 46, and the feeding groove 412.

[0067] When it is necessary to discharge the water-absorbing material in the fixed cylinder 41 into the second storage ring 43, the second storage ring 43 is first positioned above the lower portion of the fixed cylinder 41 by means of the cooperation between the second positioning hole 52 and the second positioning rod 55, and then the first storage ring 42 is positioned to a position where the connecting groove 46 is connected to the feeding groove 45 and the discharge groove 413 on the second storage ring 43 by means of the cooperation between the third positioning hole 57 and the first positioning rod 54. Figure 10 As shown), the water-absorbing material in the annular groove 411 enters the storage groove 44 of the storage ring 1 42 through the discharge groove 413, the connecting groove 46, and the feeding groove 45.

[0068] When the water-absorbing materials in the storage ring 1 42 and the storage ring 2 43 need to be replaced, the storage ring 1 42 and the storage ring 2 43 are rotated to the bottom of the fixed cylinder 41 in sequence, and the water-absorbing materials are discharged from the corresponding storage trough 44 through the corresponding discharge port 48 .

[0069] The above is a detailed introduction to the exhaust structure for a containerized diesel generator set provided by the present invention.

In summary, the contents of this specification should not be understood as limiting the present invention.
