[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The utility model provides a dangerous gas cooling device, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a power generation device 1, a detection device 2 and a cooling device 3.

[0026] The power generation device 1 includes a gas turbine box 11 and a gas turbine 12 installed in the gas turbine box 11 . An exhaust pipe 13 is fixedly connected to the gas turbine box 11 , and the gas turbine box 11 is communicated with an inlet of the exhaust pipe 13 .

[0027] The detection device 2 includes a detection box 21 and a negative pressure pump 22 and a detection head 23 installed in the detection box 21 . The inlet of the negative pressure pump 22 is connected to the outlet of the exhaust pipe 13 , and the outlet of the negative pressure pump 22 is connected to the detection head 23 .

[0028] The cooling device 3 is disposed on the exhaust pipe 13 , and is used to cool the air exhausted from the gas turbine box 11 .

[0029] When in use, under the action of the negative pressure pump 22, the air in the gas turbine box 11 enters the exhaust pipe 13, and the cooling device 3 cools the air in the exhaust pipe 13. Under the action of the negative pressure pump 22, the cooled air enters the detection box 21, and the detection head 23 detects the air composition, which not only reduces the possibility of damage to the gas turbine box 11, but also improves the power generation efficiency.

[0030] In the utility model, the air in the gas turbine box 11 passes through the exhaust pipe 13 and enters the detection box 21, and the cooling device 3 cools the air passing through the exhaust pipe 13, which not only reduces the possibility of damage to the gas turbine box 11, but also improves the power generation efficiency.

[0031] To cool the air in the exhaust pipe 13, please refer to Figure 1 In a preferred embodiment, the cooling device 3 includes a cooling box 31 sleeved on the exhaust pipe 13, and a coolant is arranged in the cooling box 31. A pump body 32, a radiator 33, an inlet pipe 34 and a discharge pipe 35 are arranged on one side of the cooling box 31. The inlet of the cooling box 31 is connected to the outlet of the inlet pipe 34, the outlet of the cooling box 31 is connected to the inlet of the discharge pipe 35, the outlet of the discharge pipe 35 is connected to the inlet of the radiator 33, the outlet of the radiator 33 is connected to the inlet of the pump body 32, and the outlet of the pump body 32 is connected to the inlet of the inlet pipe 34.

[0032] When in use, under the heat conduction of the exhaust pipe 13, the heat of the air in the exhaust pipe 13 enters the cooling box 31, and the pump body 32 is started. Under the action of the pump body 32, the coolant passes through the liquid inlet pipe 34, the cooling box 31, the liquid discharge pipe 35 and the radiator 33 in sequence, and finally returns to the pump body 32. When the coolant passes through the cooling box 31, it takes away the heat on the exhaust pipe 13, thereby cooling the air in the exhaust pipe 13. The coolant absorbs heat and heats up. When the coolant passes through the radiator 33, the coolant cools down under the heat dissipation of the radiator 33, and so on.

[0033] To increase the contact area between the coolant and the hot air, please refer to Figure 1 In a preferred embodiment, the liquid inlet pipe 34 is located on a side of the cooling box 31 close to the detection box 21, and the liquid discharge pipe 35 is located on a side of the cooling box 31 close to the gas turbine box 11.

[0034] When in use, the coolant passes through the liquid inlet pipe 34, the cooling box 31 and the drain pipe 35 in sequence. The flow direction of the coolant is from the detection box 21 to the gas turbine box 11, and the flow direction of the hot air is from the gas turbine box 11 to the detection box 21. The flow direction of the coolant is opposite to that of the hot air. In the same time, the contact area between the coolant and the hot air is increased, thereby improving the cooling effect.

[0035] In order to make the coolant contact with the exhaust pipe 13 more fully, please refer to Figure 1 In a preferred embodiment, an atomizer 36 is installed on the liquid inlet pipe 34.

[0036] When in use, under the action of the atomizer 36, the liquid coolant is converted into gaseous coolant and flows into the cooling box 31, which not only saves coolant and reduces costs, but also makes the coolant more evenly distributed in the cooling box 31 and more fully contacted with the outer wall of the exhaust pipe 13, further improving the cooling effect.

[0037] To increase the flow rate of gaseous coolant, refer to Figure 1 In a preferred embodiment, a pressure pipe 37 is fixedly connected to one side of the cooling box 31 located on the liquid inlet pipe 34 , the cooling box 31 is connected to the outlet of the pressure pipe 37 , and a high-pressure airflow is provided in the pressure pipe 37 .

[0038] When in use, under the action of the high-pressure airflow, the flow rate of the gaseous coolant in the cooling box 31 is accelerated, further improving the cooling effect.

[0039] In order to increase the contact area between the coolant and the exhaust pipe 13, please refer to Figure 2 In a preferred embodiment, a portion of the exhaust pipe 13 located inside the cooling box 31 is fixedly connected with a plurality of heat dissipating fins 14 .

[0040] When in use, the heat of the hot air is transferred to the heat dissipation fins 14 through the exhaust pipe 13, and the gaseous coolant takes away the heat from the heat dissipation fins 14. Through the arrangement of the heat dissipation fins 14, the contact area between the coolant and the exhaust pipe 13 is increased within a limited space, further improving the cooling effect.

[0041] In order to improve the heat absorption effect of the heat dissipation fins 14, please refer to Figure 2 In a preferred embodiment, the plurality of heat dissipation fins 14 are arranged in sequence and spaced apart along the length direction of the exhaust pipe 13 .

[0042] When in use, a plurality of heat dissipation fins 14 are evenly arranged on the exhaust pipe 13 , so that the heat on the exhaust pipe 13 is evenly distributed on each heat dissipation fin 14 , further improving the cooling effect.

[0043] To reduce the impact on the gas coolant flow rate, refer to Figure 2 In a preferred embodiment, a tip is provided on the side of the heat dissipation fin 14 close to the liquid inlet pipe 34 .

[0044] When in use, it complies with the principle of aerodynamics and will not affect the flow rate of the gaseous coolant in the cooling box 31, thereby further improving the cooling effect.

[0045] To facilitate the installation and removal of the cooling box 31, please refer to Figure 3 In a preferred embodiment, both ends of the cooling box 31 are fixedly connected with sealing rings 4, and the exhaust pipe 13 is fixedly connected with two sealing blocks 41, and the outer walls of the two sealing blocks 41 are respectively abutted against the inner walls of the two sealing rings 4, and the sealing ring 4 is provided with a plug hole 42, and a plug rod 43 is slidably inserted into the plug hole 42, and the sealing block 41 is provided with a slot 44 corresponding to the plug hole 42.

[0046] When in use, the cooling box 31 is sleeved on the exhaust pipe 13, the inner walls of the two sealing rings 4 are respectively in contact with the outer walls of the two sealing blocks 41, thereby improving the air tightness of the cooling box 31, the insertion hole 42 is aligned with the slot 44, the insertion rod 43 is inserted into the insertion hole 42 and the slot 44, and the cooling box 31 is fixed on the exhaust pipe 13. When disassembling the cooling box 31, the insertion rod 43 can be pulled out from the insertion hole 42 and the slot 44, which is convenient for disassembly and assembly, and convenient for replacing the cooling box 31.

[0047] In order to improve the stability of the cooling box 31, please refer to Figure 3 In a preferred embodiment, a spring is sleeved on the insertion rod 43, one end of the spring is connected to the insertion rod 43, and the other end of the spring is connected to the sealing ring 4. The spring is in a stretched state, and the spring causes the insertion rod 43 to have a tendency to slide toward the sealing block 41.

[0048] When in use, on the one hand, when the jack 42 is aligned with the slot 44, under the action of the spring restoring force, the rod 43 automatically slides into the jack 42 and the slot 44, making the operation more convenient. On the other hand, under the action of the spring restoring force, the rod 43 is not easy to fall out of the jack 42, and the fixation is more stable.

[0049] In order to better understand the present invention, the following Figure 1 - Figure 3 The working principle of the technical solution of a dangerous gas cooling device of the utility model is described in detail: under the action of the negative pressure pump 22, the air in the gas turbine box 11 enters the exhaust pipe 13, and the cooling device 3 cools the air in the exhaust pipe 13. Under the action of the negative pressure pump 22, the cooled air enters the detection box 21, and the detection head 23 detects the air composition, which not only reduces the possibility of damage to the gas turbine box 11, but also improves the power generation efficiency.
