DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0021] As Figures 1-5As shown in the figure, a multiphase flow measurement hybrid rectification assembly includes a fluid pipeline 1 provided with a fluid inlet and a fluid outlet, and a flowmeter 2 arranged on the fluid pipeline 1. One end of the fluid pipeline 1 near the inlet is provided with a mixer 3. Rectifiers 4 are arranged at positions on both ends of the flowmeter 2 on the fluid pipeline 1. The mixer 3 includes a mixing mounting plate 301, and a mixing fluid channel 302 is formed on the mixing mounting plate 301. A first rectification assembly 303 and a mixing flow assembly 304 are sequentially connected to the mixing fluid channel 302 from the end close to the fluid inlet to the end far from the fluid inlet. The rectifier 4 includes a rectification mounting plate 401, and a rectification fluid channel 402 is formed on the rectification mounting plate 401. A second rectification assembly 403 is arranged at the end of the rectification fluid channel 402 close to the fluid inlet.

[0022] In this embodiment, the axis of the mixing fluid channel 302 coincides with the axis of the mixing mounting plate 301.

[0023] In this embodiment, the first rectification assembly 303 includes two first rectification plates 3031, and the two first rectification plates 3031 cross each other to form a cross shape.

[0024] In this embodiment, the mixing flow assembly 304 includes a connecting rod 3041 and several groups of mixing flow plates 3042 arranged along the length direction of the connecting rod 3041.

[0025] In this embodiment, each group of the mixing flow plates 3042 is arranged in a crossed manner.

[0026] In this embodiment, a mixing connecting piece 305 is arranged on the mixing mounting plate 301.

[0027] In this embodiment, the axis of the rectification fluid channel 402 coincides with the axis of the rectification mounting plate 401.

[0028] In this embodiment, the second rectification assembly 403 includes two second rectification plates 4031, and the two second rectification plates 4031 cross each other to form a cross shape.

[0029] In this embodiment, a rectification connecting piece 404 is arranged on the rectification mounting plate 401.

[0030] When this component works, the fluid enters the fluid pipeline 1 from the fluid inlet. The fluid passes through the mixer 3. The mixer 3 generates a strong shearing effect through an array of cross-set mixing vanes 3042. Under the synergistic action of the first rectification component 303, the multiphase fluid with different properties is forced to mix fully. The mixed fluid enters the flowmeter 2 through the rectifier 4 arranged at the inlet end of the flowmeter 2 for measurement. The rectifier 4 ensures that the fluid has a stable flow pattern when entering the flowmeter 2, reducing the influence of turbulent flow on the measurement accuracy. The fluid measured by the flowmeter 2 passes through the rectifier 4 arranged at the outlet end of the flowmeter 2, and after further rectification, it evenly enters the mixing pipeline to maintain the fluid stability of the whole component. In this component, the first rectification component 303 and the second rectification component 403 both cross each other to form a cross shape, which is used to smooth the fluid flow and reduce vortex and pulsation phenomena.

[0031] The mixing connecting piece 305 and the rectifying connecting piece 404 of this component are used for connecting the mixer 3 and the rectifier 4 to the fluid pipeline 1. Both of them can be set as a handle or an outer tube, respectively forming an insertion type or a pipeline short-circuit type to adapt to the installation and maintenance under different working conditions.

[0032] The above-described embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
