At the same time, this system needs to be equipped with a small-power diesel generator to supply power for lighting, heating, etc. of the system, and this part also needs to be cooled. In the existing skid-mounted nitrogen compression system during system operation, the cooled high-temperature gas will directly escape into the outer cover and be discharged through the upper exhaust port of the outer cover. In this working mode, after a long time, it will cause problems such as the increase of the internal environment temperature of the entire container, the reduction of the cooler effect, and the increase of pollutants generated by the combustion of the diesel engine.

[0030] Embodiment 1

[0031] A cooling air centralized discharge device for a nitrogen compression system, used to discharge the high - temperature gas inside the nitrogen compression system outside the container when the nitrogen compression system is working. The following describes its specific structure and technical effects in detail.

[0032] As Figures 1 to 3 shown, the device includes a container 1 and a centralized discharge box 5. The base of the container 1 is equipped with a compressor head 2, a diesel engine 3, and a generator 8. The diesel engine 3 drives the compressor head 2 to work and is cooled by a blow - type diesel engine cooler 4, and the generator 8 is cooled by a blow - type generator cooler 7. The centralized discharge box 5 is fixedly installed on the base of the container 1, and its upper side extends out of the top cover 9 of the box body and is provided with an air outlet. The exhaust holes of the blow - type diesel engine cooler 4 and the blow - type generator cooler 7 are connected to the centralized discharge box 5 through pipelines. A valve with a control switch is installed on the pipeline connecting the exhaust holes of the blow - type diesel engine cooler 4 and the blow - type generator cooler 7 to the centralized discharge box 5.

[0033] By installing the centralized discharge box 5 on the base of the container 1, the high - temperature gas of multiple cooling units in the container 1 can be centrally discharged to the outside through the discharge box, thus avoiding the problem of the increase in the internal environment of the container caused by the flow of high - temperature gas in the container due to direct heat dissipation through the ventilation openings on the side wall of the conventional container, and ensuring the normal operation of the system.

[0034] Specifically, the centralized discharge box 5 includes an air collecting box, a flexible connection 6, and a top cover discharge box 10 arranged from bottom to top. The air discharge port is arranged on the side of the top cover discharge box 10. Among them, the flexible connection 6 is made of rubber, and its upper and lower sides are connected to the top cover discharge box 10 and the air collecting box through flanges. The inner side wall of the air collecting box is covered with a heat insulation layer. In this embodiment, the bottom of the top cover discharge box 10 extends outward with a mounting plate, and mounting holes are provided at corresponding positions on the mounting plate, the box body top cover 9, and the upper end of the flange. The mounting plate, the box body top cover 9, and the flexible connection 6 are fixedly connected at one time by bolts passing through the mounting holes, which simplifies the mounting structure while ensuring strength.

[0035] Using the flexible connection 6 as the intermediate connection section of the centralized discharge box 5 can effectively reduce the vibration of the centralized discharge box, ensure the operation stability of the system, and the upper and lower sides of the flexible connection 6 are connected by flanges, which is also convenient for disassembling and replacing the flexible connection 6. The flexible connection 6 is made of rubber, and at the same time, the inner side wall of the air collecting box is covered with a heat insulation layer, so that the entire centralized discharge box 5 has good heat insulation performance and can prevent the internal temperature from rising due to the heat dissipation of high-temperature gas into the container 1.

[0036] In addition, the part of the box body top cover 9 extending into the inner side of the top cover discharge box 10 has a flanging that fits upward against the inner side wall of the top cover discharge box 10, which can ensure that no water accumulates and seeps into the system interior through the connection surface of the top cover discharge box 10 under rainy conditions. A filter screen is installed at the air discharge port, and the filter screen is detachably installed at the air discharge port through bolts, which can prevent external sundries from entering the discharge box through the air discharge port and ensure the stable operation of the discharge box.

[0037] In summary, the cooling air centralized discharge device of a nitrogen compression system in this embodiment can avoid the dissipation of heat in the container by centrally discharging the high-temperature gas of multiple cooling units in the container, ensure that the internal environment temperature of the container does not rise with the operating temperature of the system, and thus achieve an ideal cooling effect.
