Embodiment 1

[0095] Such as figure 1 and figure 2 As shown, in the first specific embodiment, the exhaust fan 4 and the noise absorbing device 8 can be arranged at the rear of the nacelle 10 of the wind power generator system, and the above-mentioned multiphase flow separation device 3 can be located between the exhaust fan 4 and the exhaust device 9 Upwind direction: the exhaust fan 4 , the noise absorbing device 8 and the exhaust device 9 can be connected in sequence along the upwind direction. At the same time, the air outlet of the air exhaust device 9 can be set as flared, so as to improve the air exhaust efficiency and reduce the air exhaust noise. The air exhaust device 9 can also make the exhaust wind roughly parallel to the upwind direction and be discharged from the tail of the nacelle 10. It can be seen from fluid mechanics that the area at the tail of the nacelle 10 extending a certain distance along the upwind direction is basically a sound-absorbing zone. When the air exhau...

Embodiment 2

[0100] Please refer to Figure 12 and Figure 13 , in the second specific embodiment, the exhaust fan 4 and the noise absorbing device 8 can be arranged on the side of the nacelle 10 of the wind power generator system. At this time, the multiphase flow separation device 3 is located between the exhaust fan 4 and the exhaust device 9 The downwind direction; the side of the nacelle 10 is relative to the upwind direction, that is, the side that is in the upwind direction, or not in the fore-and-aft direction, and specifically can be a direction perpendicular to the upwind direction. At this time, in order to avoid mutual interference between the upwind incoming flow and the exhaust of the exhaust device 9, the air inlet of the multiphase flow separation device 3 can be approximately perpendicular to the air outlet of the exhaust device 9, or at a predetermined angle, usually the predetermined angle Greater than 80 degrees.

[0101] It should be noted that, in this article, when...

Abstract

The invention provides a multiphase flow separating device and a fluid transport device with the multiphase flow separating device, so that clean and dry gas phase media are formed in a separated manner and used for the fluid transport device. The multiphase flow separating device comprises a first separator and a second separator. An air inlet of the first separator is used for introducing upwind incoming flow, and an air outlet of the first separator communicates with an air outlet of the second separator. The first separator and the second separator are used for carrying out multiphase flow separating on the upwind incoming flow, and the separation precision of the first separator is smaller than that of the second separator. The air outlet of the second separator is used for outputting the gas phase media formed after separating. Thus, by means of the multiphase flow separating device, impurities in other phase states can be removed, so that the clean gas phase media are formed, and the use need of the fluid transport device can be met better.

Description

technical field [0001] The invention relates to the technical field of multiphase flow separation, in particular to a fluid transport device and a multiphase flow separation device. Background technique [0002] Wind turbines, internal combustion engines in railway locomotives, and traction motors all need to be cooled. They operate in the natural environment. When cooling with the cooling air of the natural environment, there is a multi-phase separation of the upwind flow. [0003] Take a wind generator as an example. In the prior art, a permanent magnet synchronous motor is usually used in the wind generator. Since the wind generator is used outdoors and the natural environment is harsh, the permanent magnet of the generator is not resistant to high temperature, and the cooling problem is particularly prominent. In order to achieve cooling of the generator while saving costs, air cooling is generally used in the prior art, that is, air in the natural environment is introdu...
