Embodiment Construction
[0042] see figure 1 , In the present invention, in order to facilitate manufacture and installation, the three-section API tubing tube is used to install the components respectively, and then connect them to form a complete product. The first section of the tube is equipped with a first-stage vortex rectifier 1 and an impinging flow mixer 2; the second section of the tube is equipped with a second-stage vortex rectifier 3 and a sonic oscillator 4; the third section is equipped with a three-stage vortex rectifier 5. The three sections of pipe are connected by oilfield standard 27 / 8 inch pipe thread.
[0043] For the vortex rectifiers 1, 3, and 5 (ie, the first, second, and third stages) in the present invention, please refer to the structure Figure 5 , made of 2Cr18Ni9Ti steel; it is a circular bottom plate 18 with 6 rectangular channels 20. Above each channel, a baffle plate 19 at an angle of 30° to the central axis of the bottom plate is set, and the baffle plate is welded...
