Description

Technical Field

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

[0002] The exhaust device of a containerized diesel generator set is one of its important components, mainly composed of an exhaust manifold, a bellows, a muffler, a tail gas treatment system, a muffler, etc. Among them, the muffler is mainly used to reduce exhaust noise, and it reduces the noise level by changing the air flow direction, increasing the air flow resistance, etc.

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

[0004] In the prior art, the accumulated water is often discharged by opening a drain hole at the bottom of the muffler. In order to drain the accumulated water, it is necessary to stop the generator set regularly, which affects the power generation efficiency. In addition, if the aperture of the drain hole is too small, it is easy to be blocked, and if the aperture is too large, it may damage the internal acoustic structure of the muffler, resulting in a decrease in the noise reduction performance. To solve the above technical problems, the present invention proposes an exhaust structure for a containerized diesel generator set. 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 deficiencies in the above prior art. It includes a bellows and a muffler, and a water absorption unit is installed between the bellows and the muffler through a connection unit.

[0006] The water absorption unit includes a fixed cylinder body, a first storage ring rotatably installed on the outer wall of the fixed cylinder body, and a second storage ring rotatably installed on the outer wall of the first storage ring. Semi-circular storage grooves are formed inside both the first storage ring and the second storage ring for storing water absorption materials.

[0007] Two symmetrically distributed feeding grooves are formed on the inner sides of both the first storage ring and the second storage ring. The feeding grooves are communicated with the corresponding storage grooves, and a communication groove for communicating the second storage ring with the fixed cylinder body is also formed on the inner side of the first storage ring.

[0008] Two concentrically distributed annular grooves are arranged inside the fixed cylinder body, and the parts of the left and right ends of the fixed cylinder body corresponding to the annular grooves are of a hollow structure, while the parts of the fixed cylinder body without the annular grooves are of a solid structure.

[0009] An inlet groove communicating with the outer annular groove is provided at the upper end of the fixed cylinder body, a discharge groove communicating with the outer annular groove is provided at the lower end of the fixed cylinder body, and a transfer groove for communicating the two annular grooves is provided in the solid part of the fixed cylinder body.

[0010] It further includes a switching unit for switching the positions of the first storage ring and the second storage ring to replace the water-absorbing material in the fixed cylinder body.

[0011] Preferably, the switching unit includes a positioning ring fixedly installed on the fixed cylinder body. Two symmetrically distributed positioning holes II and two symmetrically distributed positioning holes I located between the two positioning holes II are provided on the positioning ring.

The diameter of the smaller-diameter cylindrical segment is smaller than the width of the guiding groove, and the width of the guiding groove is smaller than the diameters of the positioning holes I and the positioning holes II.

[0015] Preferably, arc-shaped grooves communicating with the storage grooves are symmetrically provided inside the first storage ring and the second storage ring. A connecting spring is installed in the arc-shaped groove, and a pushing block is installed at the end of the connecting spring away from the arc-shaped groove. The pushing block is located in the storage groove and is in close contact with the inner wall of the storage groove.

[0016] Preferably, when the connecting spring extends to the limit position, the positions of the two pushing blocks corresponding to the same storage groove correspond to the positions of the corresponding two feeding grooves one by one, and the two feeding grooves are located between the two pushing blocks.

[0017] Preferably, two positioning holes III are further provided on the positioning ring. The positioning holes III communicate with the guiding grooves of the corresponding positioning holes I, and the diameter of the positioning holes III is larger than the width of the guiding grooves.

[0018] Two communicating grooves are symmetrically arranged. When the communicating groove communicates with the second storage ring through the corresponding feeding groove, the communicating groove is not communicated with the discharge groove. At this time, the position of the first positioning rod corresponds to the positioning hole III; when the communicating groove is communicated with the discharge groove, the feeding groove on the first storage ring is not communicated with the inlet groove. At this time, the position of the first positioning rod corresponds to the other positioning hole III.

[0023] 2. The present invention squeezes the water-absorbing material through the pushing block, so that the water-absorbing material always has a tendency to move towards the feeding chute, ensuring that all the water-absorbing materials can enter the fixed cylinder through the feeding chute, and further ensuring that there is always a sufficient amount of water-absorbing material in the fixed cylinder for water-absorbing treatment.

[0024] 3. The present invention drives the first storage ring and the second storage ring to rotate a set angle regularly through the switching mechanism, so as to quickly complete the conversion of their positions, and further quickly realize the update of the water-absorbing material in the solid cylinder, effectively ensuring the stability of the water-absorbing effect, and the switching mechanism is arranged on the outside, and the switching action can be realized without shutdown, and the operation is convenient.

Detailed implementation manners

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Refer to Figure 1 , an exhaust structure for a containerized diesel generator set, including a bellows 1 and a silencer 2. A water absorption unit 4 for reducing the moisture entering the interior of the silencer 2 is installed between the bellows 1 and the silencer 2 through a connection unit 3.

[0039] Specifically, refer to Figure 1 And Figure 3, the connecting unit 3 includes two hoop members 31 distributed oppositely before and after, and the two hoop members 31 before and after are fixedly connected by bolts. The cross-section of the hoop member 31 is U-shaped, and a rubber sealing ring 32 is arranged between the inner wall of the hoop member 31 and the flange of the connecting end to enhance the sealing performance after connection. Of course, flange connection or other existing connection methods can also be used for connection.

[0040] Refer to Figure 1 、 Figure 2 and Figure 3 , the water absorption unit 4 includes a fixed cylinder 41, a first storage ring 42 rotatably installed on the outer wall of the fixed cylinder 41, and a second storage ring 43 rotatably installed on the outer wall of the first storage ring 42. Semi-circular storage grooves 44 are formed inside both the first storage ring 42 and the second storage ring 43 for storing water absorption materials; the water absorption materials can be selected from high-temperature resistant water absorption particles such as activated alumina particles or ceramic-based particles.

[0041] For the convenience of connection, as Figure 1 and Figure 2 shown, connection ends are provided at both the left and right ends of the fixed cylinder 41, the corrugated pipe 1, and the muffler 2. The length of the connection end can be selected according to actual needs. A flange is integrally formed at one end of the connection end away from the corresponding fixed cylinder 41, muffler 2, or corrugated pipe 1. In addition, a plurality of through holes distributed in a honeycomb shape are formed in the solid part of the fixed cylinder 41 to reduce the exhaust back pressure.

[0042] Refer to Figure 3 and Figure 4 , two symmetrically distributed feeding grooves 45 are formed on the inner sides of both the first storage ring 42 and the second storage ring 43. The feeding grooves 45 are communicated with the corresponding storage grooves 44 to convey the water absorption materials. A communication groove 46 for communicating the second storage ring 43 with the fixed cylinder 41 is also formed on the inner side of the first storage ring 42 to facilitate the transfer of the water absorption materials between the second storage ring 43 and the fixed cylinder 41.

[0043] Refer to Figure 4 , two concentrically distributed annular grooves 411 are arranged inside the fixed cylinder 41, and the parts of the left and right ends of the fixed cylinder 41 corresponding to the annular grooves 411 are in a hollow structure (not shown in the figure) to facilitate the exhaust gas to 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.

[0044] Refer to Figure 3 and Figure 4, a feed slot 412 communicating with the outer annular groove 411 is formed at the upper end of the fixed cylinder body 41. The water-absorbing material can enter the corresponding annular groove 411 through the feed slot 412, so that the water-absorbing material can absorb water from the waste gas entering the annular groove 411. A discharge slot 413 communicating with the outer annular groove 411 is formed at the lower end of the fixed cylinder body 41. The water-absorbing material in the fixed cylinder body 41 can be discharged into the corresponding storage tank 44 through the discharge slot 413 to realize the update or replacement of the water-absorbing material. A transfer slot 414 for communicating the two annular grooves 411 is formed in the solid part of the fixed cylinder body 41. Through the transfer slot 414, the water-absorbing material can enter the inner annular groove 411 from the outer annular groove 411, so as to fill the fixed cylinder body 41 with a sufficient amount of water-absorbing material.

[0045] When the feed slot 412 corresponds to the feeding slot 45 on the first storage ring 42, the first storage ring 42 is located directly above the fixed cylinder body 41. The water-absorbing material in the storage tank 44 of the first storage ring 42 enters the outer annular groove 411 through the feeding slot 45 and the feed slot 412, and enters the inner annular groove 411 through the transfer slot 414. At this time, the water-absorbing material in the fixed cylinder body 41 can absorb the water vapor in the passing waste gas, reduce the moisture entering the muffler 2, and further reduce the accumulated water in the muffler 2.

[0046] In order to avoid the situation that the water-absorbing material cannot be completely discharged from the fixed cylinder body 41, the present invention designs the structure of the discharge slot 413 as follows: As Figure 4 shown, the discharge slot 413 is composed of two symmetrically distributed bell mouths in the front and rear and a strip-shaped slot communicated with the lower end of the bell mouth. The inclined surface structures are arranged on the sides of the two bell mouths close to each other to guide the water-absorbing material into the strip-shaped slot, and then enter the corresponding feeding slot 45 or the connecting slot 46 through the strip-shaped slot.

[0047] Refer to Figure 3 And Figure 4 , arc-shaped grooves communicating with the storage tank 44 are symmetrically formed inside the first storage ring 42 and the second storage ring 43. A connecting spring ( Figure 4 the connecting spring in is in a compressed state) is installed in the arc-shaped groove. The end of the connecting spring far from the arc-shaped groove is provided with a pushing block 47. The pushing block 47 is located in the storage tank 44 and is in close contact with the inner wall of the storage tank 44. When the storage tank 44 stores the water-absorbing material, the connecting spring drives the pushing block 47 to push the water-absorbing material, so that the water-absorbing material moves towards the feeding slot 45.

[0048] During the process of feeding the water-absorbing material in the corresponding storage tank 44 into the fixed cylinder body 41, the connecting spring drives the pushing block 47 to push the water-absorbing material towards the feeding slot 45, ensuring that all the water-absorbing material in the storage tank 44 can finally enter the fixed cylinder body 41, and further ensuring the water absorption effect.

[0049] When all the water-absorbing material in the storage tank 44 is sent into the fixed cylinder 41, when the connecting spring extends to the limit position, the positions of the two pushing blocks 47 corresponding to the same storage tank 44 correspond one by one to the positions of the corresponding two feeding grooves 45, and the two feeding grooves 45 are located between the two pushing blocks 47, so as to prevent the pushing blocks 47 from obstructing the water-absorbing material falling from the feeding grooves 45 during the process of the water-absorbing material returning from the fixed cylinder 41 to the storage tank 44 again (as Figure 6 shown).

[0050] Refer to Figure 1 and Figure 2 , the present invention further includes a switching unit 5 for switching the positions of the first storage ring 42 and the second storage ring 43 to replace the water-absorbing material in the fixed cylinder 41.

[0051] After the water-absorbing material in the fixed cylinder 41 is used for a certain period of time, its water absorption effect decreases. At this time, the switching unit 5 can be used to rotate the first storage ring 42 by 180 degrees, so that the first storage ring 42 is located below the fixed cylinder 41 and the feeding groove 45 thereon is communicated with the discharging groove 413. At this time, the water-absorbing material in the fixed cylinder 41 will return to the storage tank 44 of the first storage ring 42 again through the discharging groove 413 and the feeding groove 45.

[0052] Then, the second storage ring 43 is reversely adjusted by a certain angle through the switching unit 5 so that the communication groove 46 is correspondingly communicated with the feeding groove 412, and the second storage ring 43 originally located directly below the fixed cylinder 41 is rotated by 180 degrees through the switching unit 5 so that it rotates to directly above the fixed cylinder 41 and its feeding groove 45 is correspondingly communicated with the communication groove 46. At this time, the water-absorbing material in the second storage ring 43 can enter the interior of the fixed cylinder 41 through the feeding groove 45, the communication groove 46 and the feeding groove 412 to continue to absorb water from the waste gas.

[0053] It should be noted that the parts of the side walls of the first storage ring 42 and the second storage ring 43 corresponding to the storage tank 44 can be provided with a hollow structure to ventilate and dry the water-absorbing material inside, so that the water-absorbing material can be reused.

[0054] Since the service life of the water-absorbing material is limited, in order to ensure the water absorption effect, it needs to be replaced regularly. For this reason, as Figure 3 shown, discharge ports 48 are provided on the side walls of both the first storage ring 42 and the second storage ring 43, and the discharge ports 48 are communicated with the corresponding storage tanks 44. An inclined surface inclined towards the discharge ports 48 is provided on the side of the storage tank 44 away from the axis of the fixed cylinder 41 to guide the water-absorbing material in the storage tank 44 to the discharge ports 48, so as to replace the water-absorbing material regularly. When the water-absorbing material does not need to be replaced, the drain port is blocked by a sealing plug.

[0055] Refer toFigure 2 With Figure 5 , the switching unit 5 includes a positioning ring 51 fixedly installed on one of the connecting ends of the fixed cylinder 41. Two centrally symmetrically distributed second positioning holes 52 and two centrally symmetrically distributed first positioning holes 53 located between the two second positioning holes 52 are provided on the positioning ring 51.

[0056] A first positioning rod 54 inserted into the corresponding first positioning hole 53 is installed on the side wall of the first storage ring 42. The position of the first storage ring 42 is limited by the cooperation of the first positioning hole 53 and the first positioning rod 54; a second positioning rod 55 slidably inserted into the corresponding second positioning hole 52 from left to right is installed on the side wall of the second storage ring 43. The position of the second storage ring 43 is limited by the cooperation of the second positioning hole 52 and the second positioning rod 55.

[0057] When the first positioning rod 54 is inserted into the upper first positioning hole 53, the first storage ring 42 is located directly above the fixed cylinder 41. When the first positioning rod 54 is inserted into the lower first positioning hole 53, the first storage ring 42 is located directly below the fixed cylinder 41. Similarly, when the second positioning rod 55 is inserted into the upper second positioning hole 52, the second storage ring 43 is located directly above the fixed cylinder 41. When the second positioning rod 55 is inserted into the lower second positioning hole 52, the second storage ring 43 is located directly below the fixed cylinder 41.

[0058] Refer to Figure 2 With Figure 5 , both the first positioning rod 54 and the second positioning rod 55 are composed of a fixed rod 5a and a telescopic rod 5b slidably connected to the fixed rod 5a through a mounting spring (not shown in the figure), and the telescopic rod 5b is composed of two coaxial cylindrical segments with different diameters. Arc-shaped guiding grooves 56 are provided between the two first positioning holes 53 and between the two second positioning holes 52. The diameter of the smaller cylindrical segment is smaller than the width of the guiding groove 56, and the width of the guiding groove 56 is smaller than the diameters of the first positioning hole 53 and the second positioning hole 52.

[0059] When it is necessary to switch the positions of the first storage ring 42 and the second storage ring 43, first pull the telescopic rod 5b of the first positioning rod 54 or the second positioning rod 55, so that the larger-diameter cylindrical segment of the telescopic rod 5b is removed from the first positioning hole 53 or the second positioning hole 52, and the smaller-diameter cylindrical segment enters the first positioning hole 53 or the second positioning hole 52. At this time, the cylindrical segment can be pulled to slide in the guiding groove 56. After moving to the specified position, push the telescopic rod 5b in the reverse direction so that the larger-diameter cylindrical segment is reinserted into the corresponding first positioning hole 53 or second positioning hole 52, which can quickly complete the switching action of the first storage ring 42 and the second storage ring 43 and ensure the water absorption effect.

[0060] Refer to Figure 5, two third positioning holes 57 are further formed in the positioning ring 51, the third positioning holes 57 communicate with the guiding grooves 56 of the corresponding first positioning holes 53, and the diameter of the third positioning holes 57 is larger than the width of the guiding grooves 56.

[0061] Refer to Figure 4 , there are two symmetrically arranged communicating grooves 46. When the communicating grooves 46 communicate with the storage ring two 43 through the feeding grooves 45 on the storage ring two 43 (as shown in Figure 8 ), the feeding groove 45 on the storage ring one 42 is not communicated with the discharging groove 413. At this time, the position of the first positioning rod 54 corresponds to the third positioning hole 57. When the communicating groove 46 communicates with the discharging groove 413, the feeding groove 45 on the storage ring one 42 is not communicated with the feeding groove 412 (as shown in Figure 10 ), at this time, the position of the first positioning rod 54 corresponds to the other third positioning hole 57, so as to ensure that when replacing the water-absorbing material inside the fixed cylinder body 41, the water-absorbing materials in the storage ring two 43 and the storage ring one 42 will not be mixed together.

[0062] In specific use, the storage ring one 42 and the storage ring two 43 are successively rotated above the fixed cylinder body 41, and the water-absorbing material is sent into the corresponding storage groove 44 through the corresponding discharge port 48.

[0063] When it is necessary to send the water-absorbing material in the storage ring one 42 into the fixed cylinder body 41, through the cooperation of the first positioning hole 53 and the first positioning rod 54, the storage ring one 42 is positioned above the fixed cylinder body 41 (as shown in Figure 7 ), at this time, the feeding groove 45 on the storage ring one 42 corresponds to the feeding groove 412 in position, and the water-absorbing material in the storage ring one 42 enters the inner and outer two annular grooves 411 through the feeding groove 45 and the feeding groove 412.

[0064] When it is necessary to discharge the water-absorbing material in the fixed cylinder body 41 into the storage ring one 42, through the cooperation of the first positioning hole 53 and the first positioning rod 54, the storage ring one 42 is positioned below the fixed cylinder body 41 (as shown in Figure 9 ), at this time, the feeding groove 45 on the storage ring one 42 corresponds to the discharging groove 413 in position, and the water-absorbing material in the annular groove 411 enters the storage groove 44 of the storage ring one 42 through the discharging groove 413 and the feeding groove 45.

[0065] When it is necessary to send the water-absorbing material in the storage ring two 43 into the fixed cylinder body 41, first, through the cooperation of the second positioning hole 52 and the second positioning rod 55, the storage ring two 43 is positioned above the fixed cylinder body 41, and then through the cooperation of the third positioning hole 57 and the first positioning rod 54, the storage ring one 42 is positioned at the position where the communicating groove 46 communicates with the feeding groove 45 on the storage ring two 43 (as shown in Figure 8As shown in the figure, at this time, the communication groove 46 is also communicated with the feeding groove 412, and the water-absorbing material in the second storage ring 43 enters the two inner and outer annular grooves 411 through the feeding groove 45, the communication groove 46, and the feeding groove 412.

[0066] When it is necessary to discharge the water-absorbing material in the fixed cylinder 41 into the second storage ring 43, first, through the cooperation of the second positioning hole 52 and the second positioning rod 55, the second storage ring 43 is positioned above and below the fixed cylinder 41. Then, through the cooperation of the third positioning hole 57 and the first positioning rod 54, the first storage ring 42 is positioned at a position where the communication groove 46 is communicated with the feeding groove 45 and the discharging groove 413 on the second storage ring 43 (as Figure 10 shown in the figure). The water-absorbing material in the annular groove 411 enters the storage groove 44 of the first storage ring 42 through the discharging groove 413, the communication groove 46, and the feeding groove 45.

[0067] When it is necessary to replace the water-absorbing material in the first storage ring 42 and the second storage ring 43, the first storage ring 42 and the second storage ring 43 are successively rotated to the lower part directly below the fixed cylinder 41, and the water-absorbing material is discharged from the corresponding storage groove 44 through the corresponding discharge port 48.

For those of ordinary skill in the art, according to the idea of the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
