[0028] Sealing plate 41 is arranged between cooling tank 4 and shunt tank 2, a plurality of shunt holes 42 are uniformly arranged on sealing plate 41, and shunt holes 42 penetrate sealing plate 41.

[0029] Specifically, shunt tank 2 and cooling tank 4 are sealed and separated by sealing plate 41, and high-temperature exhaust gas is shunted into the inside of cooling tank 4 through sealing plate 41.

[0030] A first rotating shaft 22 is arranged at the center of the top surface of shunt tank 2, the top of first rotating shaft 22 penetrates the top surface of shunt tank 2, a first bearing 24 is arranged at the connection between first rotating shaft 22 and the top surface of shunt tank 2, a limiting plate 23 is arranged outside shunt tank 2 at the top surface of first rotating shaft 22, a first rotating table 21 is arranged below first rotating shaft 22, the first rotating table 21 is a circular table, a connecting shaft 3 is coaxially arranged at the bottom surface of first rotating table 21, the connecting shaft 3 penetrates sealing plate 41, a second bearing 31 is arranged at the connection between connecting shaft 3 and sealing plate 41, and the lengths of the two ends of connecting shaft 3 beyond sealing plate 41 are the same.

[0031] Specifically, after the high-temperature and high-pressure exhaust gas enters the diversion tank 2, it drives the rotation of the first turntable 21 and the first rotating shaft 22. The first rotating shaft 22 rotates independently of the diversion tank 2 through the first bearing 24, and the first turntable 21 and the first rotating shaft 22 are limited by the limiting plate 23. The rotation of the first turntable 21 drives the connecting shaft 3 to rotate synchronously, so that the connecting shaft 3 rotates simultaneously inside the diversion tank 2 and the cooling tank 4. The second bearing 31 allows the connecting shaft 3 to rotate independently of the sealing plate 41, and the connecting shaft 3 is symmetrical to each other in the diversion tank 2 and the cooling tank 4.

[0032] The center of the air duct 12 is located at the connection between the first turntable 21 and the first rotating shaft 22, and the diversion hole 42 is located on the outer side of the bottom surface of the first turntable 21.

[0033] Specifically, the high-temperature and high-pressure exhaust gas directly drives the rotation of the first turntable 21 and the first rotating shaft 22, and enters the diversion hole 42 from the outside of the first turntable 21.

[0034] The connecting shaft 3 is connected to a second turntable 5 inside the cooling tank 4. The shape of the second turntable 5 is the same as that of the cooling tank 4.

A flow guide platform 52 is provided at the other end of the second rotating shaft 51. A flow guide seat 53 is provided at the other end of the flow guide platform 52. The second turntable 5, the second rotating shaft 51 and the flow guide platform 52 are internally connected. The flow guide seat 53 is connected to the flow guide platform 52.

Through the rotation of the second turntable 5, the second turntable 5, the second rotating shaft 51, the diversion platform 52 and the diversion seat 53 are driven to rotate synchronously. When the diversion seat 53 rotates, a low-pressure zone is formed above the interior of the cooling water tank 7, which facilitates the intake of circulating water from the cooling water tank 7 into the interior of the second turntable 5, the second rotating shaft 51 and the diversion platform 52, thereby cooling the high-temperature exhaust gas entering the cooling tank 4.

[0036] The second turntable 5, the second rotating shaft 51, the flow-guiding platform 52, and the flow-guiding seat 53 are all made of materials with good thermal conductivity.

[0037] Specifically, it facilitates heat exchange between the second turntable 5, the second rotating shaft 51, the diversion platform 52, and the diversion seat 53 and the high-temperature exhaust gas.

[0038] A circulation pipe 71 is provided at the center of both sides of the cooling water tank 7. The circulation pipe 71 penetrates the side wall of the cooling water tank 7, and the pair of circulation pipes 71 are symmetrical to each other.

[0039] Specifically, the water inside the cooling water tank 7 is circulated through the circulation pipe 71, and the inside of the cooling water tank 7 is connected to the outside.

[0040] During use, the high-temperature exhaust gas enters the diversion tank 2 through the intake pipe 1, and is pressurized by the booster pipe 11, which drives the rotation of the first turntable 21 and the first rotating shaft 22. The high-temperature exhaust gas enters the interior of the cooling tank 4 through the diversion hole 42. The rotation of the first turntable 21 and the first rotating shaft 22 drives the second turntable 5 to rotate synchronously, and draws the cooling circulating water inside the cooling water tank 7 into the interior of the second turntable 5, the second rotating shaft 51 and the diversion platform 52. The diversion hole 42 diverts the high-temperature exhaust gas. When the second turntable 5 rotates, it drives the high-temperature exhaust gas to rotate around the second turntable 5, which facilitates heat exchange between the second turntable 5, the second rotating shaft 51 and the diversion platform 52 and the high-temperature exhaust gas. After being cooled down, the exhaust gas is discharged from the exhaust pipe 6, and the exhaust pipe 62 reduces the speed of the exhaust gas.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
