DETAILED DESCRIPTION

[0020] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution: a high-temperature flue gas cooling device for a gas engine, comprising a fixed body 1, the inner wall of the fixed body 1 is threadedly connected to a moving body 4, a cooling chamber 5 is opened at the bottom of the moving body 4, a rotating ring 10 is provided at the lower end of the moving body 4, a connecting sleeve 13 is provided at the lower end of the rotating ring 10, the surface of the connecting sleeve 13 is slidably connected to the inner wall of the fixed body 1, and the inner wall of the connecting sleeve 13 is rotatably connected to a rotating sleeve 11. Through the arrangement of the moving body 4, the cooling chamber 5, the rotating ring 10, the connecting sleeve 13 and the rotating sleeve 11, a storage space is provided for cooling water, so that the device can cool the high-temperature flue gas.

[0022] A liquid injection port 3 is provided on the surface of the fixed body 1, and a liquid discharge port 2 is provided on one side of the fixed body 1 to provide an inlet and outlet channel for cooling water. A water inlet 7 connected to the interior of the cooling chamber 5 is provided on the surface of the movable body 4, and a drain port 6 connected to the cooling chamber 5 is provided on the surface of the movable body 4, so that cooling water can enter the cooling chamber 5 and be discharged.

[0023] The surface of the rotating ring 10 is fixedly connected with connecting rods 16 arranged at equal distances around the circumference, and the end of the connecting rod 16 away from the rotating ring 10 is fixedly connected with a bowl-shaped force-bearing plate 15. The force-bearing plate 15 and the liquid injection port 3 are located at the same height, so that the cooling water entering the fixed body 1 from the liquid injection port 3 can smoothly impact the force-bearing plate 15, ensuring the smooth operation of the device. At the same time, the bowl-shaped force-bearing plate 15 increases the contact area between the force-bearing plate 15 and the cooling water, and can amplify the impact force of the cooling water on the force-bearing plate 15, ensuring that the connecting sleeve 13 can rotate smoothly in the fixed body 1, ensuring the smooth operation of the device.

[0024] The inner wall of the rotating ring 10 is fixedly connected with L-shaped rods 17 arranged at equal intervals around the circumference, and the lower ends of the L-shaped rods 17 are fixedly connected to the surface of the rotating sleeve 11, so that when the rotating ring 10 rotates, it can drive the rotating sleeve 11 to rotate synchronously through the connection of the L-shaped rods 17. The bottom of the connecting sleeve 13 is fixedly connected with a scraper 12 that fits the shape of the rotating sleeve 11, and the surface of the scraper 12 is in contact with the surface of the rotating sleeve 11.

[0025] The upper and lower ends of the rotating ring 10 are fixedly connected with connecting rings 14. The surfaces of the two connecting rings 14 are respectively slidably connected to the interior of the lower end of the moving body 4 and the interior of the upper end of the connecting sleeve 13, so as to connect the rotating ring 10 between the moving body 4 and the connecting sleeve 13.

[0026] A sealing ring 18 is fixedly connected to the surface of the rotating sleeve 11. The surface of the sealing ring 18 slides with the inside of the connecting sleeve 13 to seal the gap between the rotating sleeve 11 and the connecting sleeve 13, thereby preventing cooling water from leaking into the fixed body 1 and affecting the use of the equipment. A sealing ring 18 is also provided between the connecting sleeve 13 and the fixed body 1 and between the movable body 4 and the fixed body 1, thereby preventing leakage of cooling water.

[0027] The inner wall of the cooling chamber 5 is fixedly connected with a fixed shaft 8, and the surface of the fixed shaft 8 is fixedly connected with stirring plates 9 arranged at equal distances. Therefore, through the setting of the stirring plates 9, the cooling water in the rotating sleeve 11 can be stirred when the rotating sleeve 11 rotates, so that the heated cooling water in the rotating sleeve 11 can be quickly stirred and mixed with the newly injected cooling water, thereby improving the cooling rate of the heated cooling water under the rotating sleeve 11, thereby improving the cooling effect of the device on the flue gas, improving the use effect of the equipment, and worthy of promotion.

[0028] Working principle: When cooling water is injected into the fixed body 1 through the liquid injection port 3, the cooling water impacts the force-bearing plate 15, thereby driving the rotating ring 10 to rotate between the movable body 4 and the connecting sleeve 13, and driving the rotating sleeve 11 to rotate at the lower end of the connecting sleeve 13 through the L-shaped rod 17. Since the connecting sleeve 13 does not rotate, the rotating sleeve 11 and the scraper 12 slide against each other, so that the scraper 12 scrapes off the dirt on the surface of the rotating sleeve 11 and blows it out from the fixed body 1 with the flow of flue gas, avoiding the adhesion of a large amount of dirt such as flue gas particles on the surface of the rotating sleeve 11, reducing the heat exchange efficiency between the cooling water and the flue gas in the rotating sleeve 11, thereby improving the cooling effect of the device on the flue gas.

[0029] At the same time, due to the rotation of the rotating sleeve 11 and the fixed shaft 8 being in a fixed state, relative movement occurs between the rotating sleeve 11 and the stirring plate 9, so that the stirring plate 9 can stir the heated cooling water in the rotating sleeve 11, thereby accelerating the mixing efficiency between the heated cooling water and the newly injected cooling water, and improving the cooling efficiency of the cooling water in the rotating sleeve 11 on the flue gas.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
